Description

This application is based on a partial continuation application of US Patent Application No. 14 / 521,330 (invention title "Measured value transmission system for small measuring instruments") filed on October 22, 2014. Incorporates the disclosure of this application as a part of this specification.

The present invention relates to a measurement system, and more particularly to a battery-free data transmission module accessory for wirelessly transmitting measurement data from a battery-powered portable measuring device to a remote data node. The present invention particularly relates to a data transmission module, a wireless transmission method using the data transmission module, and a wireless transmission system.

Currently, various battery-powered portable (eg, small) measuring devices are available. As an example of a battery-powered portable measuring device, there is a displacement amount measuring device such as a small electronic caliper. It can be used to accurately measure each dimension of an object (eg, measure a machined area to see if it is within tolerance reference values). Patent Documents 1 to 3 by the same applicant disclose typical electronic calipers.

In general, reducing the power consumption of such calipers and other battery-powered mobile measuring devices also reduces the number of batteries required, and the calipers and other battery-powered mobiles until these batteries need to be replaced or recharged. The operating period of the measuring equipment is extended. However, it is difficult to reduce the amount of power required for such equipment in units of "microwatts" or more. Such equipment is required to make extremely accurate measurements. Due to the complexity of the signal processing techniques developed for use in such equipment, it is also complicated to design circuits that operate at low voltage and low power while achieving the desired accuracy. There are many. Moreover, the power resources required for a particular function (such as wireless transmission of measurement data) may be much higher than the power required for basic operation and measurement. In addition to the problem of high power requirements for this particular function, various factors (eg, accidentally moving a caliper jaw while performing a measurement function) can be reliable or predictable for the measurements. There is also the problem that it may affect sexuality.

In this "Means for Solving the Problems", a simplified version of the concept selected from each of the concepts described in detail in the following "Mode for Implementing the Invention" will be introduced.

Based on the needs outlined above, and based on the further needs and challenges outlined as the introduction of FIGS. 7-10, and, of course, the wireless data transmission module operates without the need for battery power or manual operation. It is desirable to continue to supply measurement data almost continuously. It is desirable that the wireless data transmission module be capable of responding to remote requests for measurement data received from remote data nodes. Along with / instead of this, when the remote data node is in the vicinity of the radio data transmission module, the radio data transmission module simply (regardless of the remote request) transmits the measurement data automatically or semi-automatically. Is desirable. It is desirable that the wireless data transmission module be compact, lightweight, ergonomically easy to use, and easy to use after being attached to various small battery-powered portable measuring devices. At the same time, it is desirable that the wireless data transmission module be installed in an inconvenient location and be able to operate with a battery-powered measuring device mounted on the machine itself (such as a drilling machine or lathe). The wireless data transmission module should operate over a convenient distance from the remote data node. Based on the above and other considerations, the following disclosures have been conceived.

The data transmission module inputs measurement data from a battery-powered portable measuring device and wirelessly transmits the corresponding measurement data signal to a remote data node. The remote data node is configured to generate at least one energy supply field (eg, to power the data transmission module) and to wirelessly receive the measured data signal from the data transmission module. In each implementation, the data transmission module has a main body unit, a field reception unit, a wireless data generation unit, and a data transmission / energy management circuit. The main body is configured to be physically connected to the battery-powered portable measuring device. The field receiver is configured to receive the energy supply field from the remote data node. The wireless data generation unit wirelessly transmits the measurement data signal to the remote data node. The data transmission / energy management circuit has a data connector configured to connect to the data connector of the battery-powered portable measuring device.

In each implementation, the data transmission / energy management circuit is configured to perform various operations, such as the following operations.

FIG. 1 is a block diagram showing an example of a measurement system 10 including a measurement value transmission system 150 according to the first exemplary embodiment. In the figure, the measured value transmission system 150 is connected to the small measuring device 101 and wirelessly transmits measurement data from the small measuring device 101 to the remote system 180. The transmitted measurement data TMD1 may be related to one or more measured values (for example, measurement dimension MD1) of the workpiece (measurement object) WP acquired by the small measuring device 101. The remote system 180 has a computer system 182 operably connected to a keyboard 184, a monitor 186, and / or other input / output devices. The measurement data of the small measuring device 101 may be displayed on the display 109 of the small measuring device 101 and / or the monitor 186 of the remote system 180.

The measured value transmission system 150 has an antenna 161 for wirelessly transmitting the measured data. On the other hand, the remote system 180 has an antenna 181 for receiving the transmitted measurement data TMD1. In each implementation, when the remote system 180 succeeds in receiving the transmitted measurement data TMD1, the transmission success signal STS1 is wirelessly transmitted using the antenna 181. The measured value transmission system 150 receives the transmission success signal STS1 using the antenna 161. As will be described in more detail later, in each implementation, when the measured value transmission system 150 receives the transmission success signal STS1 or confirms the transmission success by another method, various operations (for example, wireless transmission is stopped). The transmission cycle end operation, the data retention release operation to end the data retention state, the display display of the notification indicating that the transmission was successful, etc.) are executed.

As will be described in more detail later, in each implementation, the measured value transmission system 150 has a power generation unit. The power generation unit converts the work assigned by the user (for example, an operation on a power generation actuator such as a button, a slide, or a lever) into electric power for wirelessly transmitting measurement data to the remote system 180. Alternatively, the main battery resource in the small precision measuring instrument may be used for wireless transmission of data, or the main power source consumes a large amount of power by supplying power for wireless transmission from an external power generator. Please understand that you may avoid this. In each implementation, the measured value transmission system 180 may additionally or optionally have a data retention actuator. The data retention actuator, when manually operated by the user, initiates a data retention state that anchors a set of measurement data that will later be wirelessly transmitted to the remote system 180. It should be understood that this data retention state can have various advantages. For example, as one of the advantages, the user temporarily stores the measurement data (eg, when the user operates the power generation actuator and / or the transmission actuator and other parts, the user mistakes the caliper jaw. The original measurement value can be confirmed on the display (and / or display 109) (for example, in the measurement value transmission system).

2A and 2B are measurement value transmission systems 250 according to a second exemplary embodiment for wirelessly transmitting measurement data to a remote system (eg, the remote system 180 of FIG. 1), the small measuring device. It is a figure which shows the measured value transmission system 250 in the state connected to 201. It is understood that some feature parts of the measured value transmitting system 250 are the same as the feature part of the measured value transmitting system 150 of FIG. 1 and are interpreted to operate in the same manner unless otherwise described below. sea bream. In the embodiment of FIG. 2A, the small measuring device 201 is a caliper capable of outputting measurement data obtained by measuring the workpiece WP (for example, corresponding to the measurement dimension MD2 of the workpiece WP). The measured value transmission system 250 has a first actuator 255 (eg, a button). In each implementation, the first actuator 255 functions as a power generation actuator, a transmission actuator and / or a data retention actuator. This will be explained in more detail later.

In each implementation, the first actuator 255 forms part of the transmit activation unit TAP2 and / or the power generation unit EGP2. For example, as shown in FIG. 2B, the transmission activation unit TAP2 includes a first actuator 255 (shown as, for example, a transmission actuator) and each part of the circuit elements (circuits) 253A and 253B of the circuit board assembly 251. In the figure, the output side wireless transmission unit WTP on the circuit board assembly 251 includes each unit of the circuit element 253B and the antenna 261. An example of circuit elements 253A and 253B will be described in more detail later with reference to FIG. When the user operates the first actuator 255, each operation including the transmission operation cycle is started, whereby the switching function of the circuit element 253A is activated. When the switching function of the circuit element 253A is activated, the transmission activation unit TAP2 operates. The transmission operation cycle includes wirelessly transmitting measurement data to a remote system using the circuit element 253B connected to the antenna 261.

As further shown in FIGS. 2A and 2B, the power generation unit EGP2 has a first actuator 255 (for example, shown as a power generation actuator), a work amount conversion element WCE, and each part of the circuit element 253A. In order to operate the power generation unit EGP2, the first actuator 255 can be manually operated by the user, and is used as a work amount conversion element WCE (for example, a piezoelectric element such as a piezoelectric film sensor or an igniter, an electromagnetic generator, etc.). It is configured to give work to it. In FIG. 2A, the first actuator 255 is shown as a button. On the other hand, in another mounting embodiment, the first actuator 255 is another element (for example, a slide, a lever, etc.), and the work amount may be given to the work amount conversion element corresponding thereto. I want to be understood. The work amount conversion element WCE converts this work amount into electric power. The power obtained by this conversion is supplied to at least an output side wireless transmission unit WTP (including, for example, each unit of the circuit element 253B and the antenna 261) that wirelessly transmits the measurement data to the remote system.

In one implementation, the transmission activation unit TAP2 consumes a first amount of power when performing one transmission operation cycle, and the power generation unit EGP2 performs one actuation cycle of the power generation actuator 255. , Are configured to generate a second amount of power that is greater than the first amount of power. In other words, in the embodiment of FIG. 2, according to the overall operation of the measured value transmission system 250, when the user presses the actuator button 255 once, the wireless transmission of the measured data is started and the measured data is transmitted wirelessly. A sufficient amount of power is generated.

In each implementation, the first actuator 255 may additionally or optionally have a function as a data holding actuator. In such an implementation, when the user manually operates the first actuator 255, the operation of starting the data holding state is executed. Here, the data retention state means a state in which a set of measurement data to be wirelessly transmitted to a remote system later is fixed. In one implementation, the small measuring device 201 may include a measured value display 209. The small measuring device 201 may execute a holding mode of operation including fixing the measured value being displayed on the measured value display 209. In such an implementation, these operations of initiating a data holding state for fixing a set of measurement data are carried out by holding the above operation in the small measuring device 201 through the device side data connection unit DCP2 (including, for example, the female connector 219). Includes initiating a mode. This will be explained in more detail later. In another implementation, these actions of initiating a data retention state that anchor the set of measurement data are the circuit elements 253A of the measurement value transmission system 250 for later wireless transmission of the set of measurement data to the remote system. It may include temporarily storing in the memory MEM of.

In one implementation, the transmit operation cycle further includes a data retention release operation. This data retention release operation is executed after the measurement data has been successfully transmitted. By executing the data retention release operation, the data retention state ends. For example, as described above with reference to FIG. 1, when the remote system 180 receives the wirelessly transmitted measurement data, it returns the “transmission success” signal STS1 to the measured value transmission system 250. In such an example, when the measured value transmission system 250 receives the transmission success signal STS1, the data retention release operation is executed and the data retention state is terminated. It should be understood that such a function allows the user to know that the measurement data has been successfully transmitted and to perform the next measurement process. The measured value displayed on the measured value display 209 may be kept fixed until the next measurement process is completed.

In one implementation, the transmit operation cycle further includes a transmit cycle end operation. This transmission cycle end operation is executed after the measurement data has been successfully transmitted. As a result, at least a part of the operation of the measured value transmission system 250 is terminated. This end-of-operation state continues until the user manually operates the actuator of the measured value transmission system 250 (eg, actuator 255) again. During this end operation, the power consumption can be reduced and the amount of arithmetic processing can be kept constant. The measured value transmitting system 250 also includes a radio receiving unit WRP (including, for example, an antenna 261 and each unit of the circuit element 253B) in addition to the radio transmitting unit WTP. In this case, the transmission cycle end operation is executed after receiving the transmission success signal STS1 from the remote system 180, as described above. Additionally or additionally, the measured value transmission system receives a transmission success signal from the remote system within a certain period of time after starting the wireless transmission of the measurement data when the transmission of the measurement data fails (for example, the transmission of the measurement data is started. If not), an error message may be presented to the user.

In one implementation in which the first actuator 255 performs a plurality of functions as a transmit actuator, a power generation actuator and / or a data retention actuator, a state-dependent operation is used. For example, in one implementation, the state-dependent operation is such that the user operates the actuator 255 (for example, presses the button 255) to execute the operation of starting the data holding state, and then operates the actuator 255 again. Means that a series of operations including a transmission operation cycle is started and / or the power required for data transmission is generated. In such an implementation, the first time the button 255 is pressed, the measurement data is fixed (eg, this allows the user to see if the measured value is accurate on the display, and also for the small measuring device 201. Even if you accidentally move some part, the measured value does not change). Then, when the button 255 is pressed for the second time, the fixed / confirmed measurement data is wirelessly transmitted to the remote system 180. As described above, in one embodiment, when the transmission success signal STS1 from the remote system 180 is received, the fixed release of the data holding state and / or the display indicating that the transmission is successful is started. After that, the next measured value is acquired and transmitted by the same procedure. That is, when the button 255 is pressed for the first time, the new measurement data is fixed, and then when the button 255 is pressed for the second time, the wireless transmission of the new measurement data is started.

Alternatively, each implementation may be provided with a second actuator 257 that functions as a transmit actuator and / or a data retention actuator. For example, while the work is converted to electric power by using the first actuator 255 having the work conversion element WCE, the second actuator 257 connected to the circuit element 253A provides a switching function in one implementation. It is used to perform and may function as a transmit actuator and / or a data retention actuator. In one implementation in which the second actuator 257 functions as a transmit actuator, in one configuration, first, when the user operates the first actuator 255, the power used for wireless transmission is generated, and then the user second. By operating the actuator 257, wireless transmission of measurement data may be started. In one implementation in which the second actuator 257 functions as a data holding actuator, in one configuration, first, when the user operates the second actuator 257, the measurement data is fixed, and then the user presses the first actuator 255. When operated, it may initiate a transmission operation cycle and / or generate power used for wireless data transmission.

As will be described in more detail later, in each implementation, the measured value transmission system 250 may have a transmission activation unit TAP2 and a data retention function that does not use the power generation unit EGP2. For example, the measured value transmission system 250 is assumed to have an external battery and / or is connected to the power source of the small measuring device 201 and utilizes the power from the power source. In the one mounting embodiment, one actuator executes the function of the data holding actuator and the function of the transmitting actuator. For example, in one configuration, the measurement data may be fixed when the user performs the first operation of the actuator, and then the transmission operation cycle may be started when the user performs the second operation of the actuator. At this time, the electric power required for these operations is supplied from the power source (for example, a battery) of the small measuring device 201 or the measured value transmitting system 250. Alternatively, in one configuration, once the user operates the actuator, the measurement data may be fixed and the transmission operation cycle may be started (for example, this allows the user to accurately display the measurement data displayed on the display. It can be confirmed whether or not, and as explained in the previous example, the fixed state of the measurement data can indicate that the transmission process has not been successful yet).

The measured value transmitting system 250 shown in the examples of FIGS. 2A and 2B is stored in the main body BP2 and constitutes the measured value transmitting module MTM2. In the measured value transmission module MTM2, at least the actuator 255 (eg, transmission actuator, power generation actuator, and / or data retention actuator) is visible to the user. As will be described in more detail later, the measured value transmission module MTM2 is configured to mechanically and / or electronically connect to at least one connection feature unit (for example, data connection unit DCP2) of the small measuring device 201. You may. In some cases, the measured value transmission module MTM2 does not include a battery and does not consume power from the small measuring device 201 (for example, instead receives the required power supply from the power generator EGP2). It may be configured to work. By connecting the measured value transmission module MTM2 to an existing caliper (for example, via an existing data port such as the data port of the data connection unit DCP2), a wireless transmission function of measurement data accompanied by a data holding operation and a wireless transmission function / Or it is possible to add a function of generating power required for wireless transmission of measurement data. In another embodiment, the measured value transmission system is housed in a small measuring instrument to provide such functionality. This will be described in more detail later with reference to FIG.

In the example of FIG. 2, the connection feature portion CF2A of the measured value transmission system 250 has a device-side male connector 263 at the bottom. The connection feature portion CF2B provided as an option has a meshing portion. A special meshing release tool is required to remove the meshing portion. The device-side male connector 263 of the measured value transmission system 250 is housed in the data connection unit DCP2. The data connection unit DCP2 has a female connector 219 of the small measuring device 201. The female connector 219 is a part of the primary output port of the small measuring device 201 for supplying measurement data to an external device (for example, the remote system 180 in FIG. 1). In one mounting embodiment, the female connector 219 includes a sealed elastic interconnector in which a plurality of conductive portions and non-conducting portions are alternately laminated. This is described in more detail in Patent Document 4 by the same applicant. The device-side male connector 263 can be a complementary connector. However, more generally, any suitable connection method can be used. Further, the female connector 219 supplies an interface such as an RS232 port, a serial port, a digital interface compatible with a connector (for example, a flat connector, a circular 6-pin connector, a flat 10-pin connector, etc.), or measurement data to an external device. Can be part of any other output port for. Several types of output ports and connectors are described in more detail in Patent Document 5 by the same applicant. Such connectors are often used to connect small measuring devices to external devices (eg, the remote system 180 in FIG. 1) by wire, but instead, as described herein, a measured value transmission system. It should be understood that measurement data can be wirelessly transmitted to a remote system by using such a connector to attach the device to a small measuring device.

As shown in FIG. 2A, the small measuring device 201 has a main scale 202 having a main scale and a slider 206 arranged on the main scale 202. The slider 206 is slidably arranged on the main scale 202 along the vertical axis of the main scale 202. The main scale 202 includes an inner measuring jaw 203 and an outer measuring jaw 204. The inner measuring jaw 203 and the outer measuring jaw 204 are attached to the upper and lower edges of the base end of the scale, respectively. The small measuring device 201 further includes a scale 205. The scale 205 is attached to the inner portion of the scale along the longitudinal axis direction. The inner measurement jaw 203 and the outer measurement jaw 204 are each integrated with the main scale 202.

An inner measurement jaw 207 and an outer measurement jaw 208 are arranged on the outer surface of the slider 206. The inner measuring jaw 207 and the outer measuring jaw 208 are attached to the upper and lower edges of the proximal end, respectively. Further, a measured value display 209 is arranged in front of the slider 206. A set screw 210 is screwed into the slider 206. The position of the slider 206 is fixed by the set screw 210. A feed roller 211 is attached to the outer surface of the slider 206. When the feed roller 211 comes into contact with the main scale of the main scale 202 and rotates, the slider 206 moves.

During the measurement operation, the slider 206 is moved by the feed roller 211 so that the inside of the measurement jaw 207 or the outside of the measurement jaw 208 comes into contact with the target portion of the workpiece WP together with the inside of the measurement jaw 203 or the outside of the measurement jaw 204. .. At this time, the displacement of the slider 206 is detected by the scale 205 provided on the main scale of the main scale 202 and the detection head of the slider 206. The signal of the detected measured value (shown as the measured dimension MD2 of the workpiece WP) is processed as measurement data by the circuit board (not shown). This measurement data is displayed as a display measurement value DM2 on the measurement value display 209 provided on the front side of the slider 206, and / or, as described above, is displayed by the measurement value transmission system 250 as a remote system (for example, the remote in FIG. 1). It is transmitted wirelessly to the system 180).

FIG. 3 is a perspective view showing a measured value transmission system 350 according to a third exemplary embodiment, which is connected to the small measuring device 301. It is understood that the measured value transmitting system 350 has the same characteristics as the measured value transmitting systems 150 and 250, and is interpreted to operate in the same manner as the measured value transmitting systems 150 and 250 unless otherwise specified below. I want you to understand. As shown in FIG. 3, the measured value transmitting system 350 has an actuator 355, a device-side male connector 363, a plurality of meshing fasteners 365, and a main body portion BP3 as a part of the measured value transmitting module MTM3. .. The device-side male connector 363 is inserted into the female connector 219 provided in the data connection portion DCP3 of the small measuring device 301, similarly to the device-side male connector 263 of FIG. A plurality of holes 217 are formed in the small measuring device 301. Each meshing fastener 365 of the measured value transmission system 350 is inserted into each of these holes 217. In each mounting embodiment, each mesh fastener 365 can be a fixed fastener, a semi-fixed fastener, or a removable fastener.

In each implementation, the actuator 355 functions as a power generation actuator, a transmission actuator, and / or a data retention actuator, similar to the operation described above for the actuator 255 of FIG. In the example of FIG. 3, there is only one actuator 355 provided as part of the measured value transmission system 350. Therefore, in one implementation in which the power generation unit is provided in the measured value transmission system 350, when the user operates the actuator 355 once (for example, pressing the button 355), the transmission operation cycle is started and the wireless data is transmitted. Generates the power required for transmission. Additional or alternative, state-dependent actions may be utilized. For example, in one implementation in which the data retention operation is performed by the measured value transmission system 350, the data retention state is started when the user operates the actuator 355 by the state-dependent operation, and then the data is transmitted when the user operates the actuator 355 again. A series of operations including an operation cycle can be started and / or the power required for data transmission can be generated. In such an implementation, the first time the button 355 is pressed, the measurement data is fixed (for example, by this, the user confirms whether the measured value fixed on the measured value display 209 of the small measuring device 201 is accurate. Can be done). Then, when the button 355 is pressed for the second time, the fixed / confirmed measurement data is wirelessly transmitted to the remote system 180. In each embodiment, when the transmission success signal from the remote system 180 is received or when it is determined that the transmission is successful by another method, the measured value display 209 is used to notify the user to that effect. For example, as described above, in one implementation, the notification may be obtained by releasing the fixation of the measured value on the measured value display 209. Alternatively, other display may be performed on the measured value display 209 (for example, displaying the character "OK").

FIG. 4 is a measured value transmitting system 450 according to a fourth exemplary embodiment in which a recess for accommodating the measured value transmitting system 450 is formed, and is a measured value transmitting system connected to a small measuring device 401. It is a perspective view which shows 450. The measured value transmitting system 450 has the same characteristics as the measured value transmitting systems 150, 250 and 350, and operates in the same manner as the measured value transmitting systems 150, 250 and 350 unless otherwise specified below. Please understand that it is interpreted as. The measured value transmitting system 450 and the small measuring device 401 are substantially the same as the measured value transmitting system 350 and the small measuring device 301 in FIG. 3, but mainly the recess 410 of the small measuring device 401 and the measured value. It is different from the display 459 of the transmission system 450.

As shown in FIG. 4, the recess 410 as a whole has a shape that matches the external dimensions of the main body portion BP4 of the measured value transmission module MTM4. The measured value transmitting module MTM4 includes a measured value transmitting system 450. The recess 410 is provided with a female connector 219 of the data connection portion DCP4 at the bottom thereof. The device-side male connector 463 of the measured value transmission system 450 is inserted into the female connector 219. The recess 410 further has a plurality of holes 217. Each meshing fastener 465 of the measured value transmission system 450 is inserted into each of these holes 217.

In one mounting embodiment, when the measured value transmitting system 450 is fixed in the recess 410 by the meshing fastener 465, the main body BP4 of the measured value transmitting system 450 is substantially equal to the surface of the small measuring device 401. The dimensions are such that they are flush with each other and do not excessively protrude from the surface. Forming such a recess 410 in the small measuring device 401 in the present embodiment integrally fits the measured value transmission system 450 into the recess 410 while maintaining the ideal ergonomic design of the small measuring device 401. It is convenient in that it can be done. Alternatively, the measured value transmitting system 450 may be omitted for cost reduction, and the measured value transmitting system 450 may be purchased and installed after the fact as needed. Further, the same measured value transmission system 450 can also be used for the small measuring device of the above-described embodiment (for example, the small measuring device 301 of FIG. 3) in which the recess 410 is not formed. As a result, the number of models (models) of the measured value transmission system 450 and / or the small measuring devices 301 and 401 can be reduced, and the required inventory quantity can be reduced, which is advantageous in terms of cost.

In each implementation, the display 459 presents the user with various information about the operation of the measured value transmission system 450. For example, when the display 459 receives the transmission success signal from the remote system 180 instead of the measurement value display 209 of the small measuring device 201, or when it is determined by another method that the transmission is successful, the user is notified accordingly. Notify. For example, when it is determined that the transmission is successful, the character "OK" is displayed on the display 459 as shown in FIG. In other implementations, a larger display may be used (eg, displaying a fixed value of the measured data value, etc.). It should be understood that in any of the measured value transmission systems 150, 250 and 350, a plurality of displays of the same type may be provided.

FIG. 5 is a measurement value transmission system 550 according to a fifth exemplary embodiment for wirelessly transmitting measurement data to a remote system, and is a measurement value transmission system 550 in a state of being stored in a small measuring device 501. It is a front view which shows. The measured value transmitting system 550 has the same characteristics as the measured value transmitting systems 150, 250, 350 and 450, and is the same as the measured value transmitting systems 150, 250, 350 and 450 unless otherwise specified below. Please understand that it is interpreted as working with. The main body BP included in the measured value transmitting systems 250, 350 and 450 is a part of the removable and portable measured value transmitting module MTM. In contrast, the measured value transmission system 550 is integrated as a part of the small measuring device 501 and stored in the small measuring device 501 (for example, it is removable from the small measuring device 501 and is removable from the other). It is not supposed to be a normal operation) that it can be attached to the measuring equipment of.

In the example of FIG. 5, the measured value transmission system 550 has one actuator 555 (eg, represented as a “hold / transmit” button 555). Therefore, as described above with reference to FIG. 3, in each implementation, the state-dependent operation is used for one actuator 555, as in FIG. For example, in one implementation, according to the state-dependent operation function, when the user operates the actuator 555, the data holding state is started, and then when the user operates the actuator 555 again, a series of operations including a transmission operation cycle are performed. And / or generate the power required for data transmission. At the time of operation, the measurement dimension MD2 of the workpiece WP is processed as measurement data, and the processed data is displayed as the display measurement value DM5 on the measurement value display 209, and / or the measurement value, as in the mounting embodiment of FIG. 2 described above. Wireless transmission is performed by the transmission system 550 to a remote system (for example, the remote system 180 in FIG. 1).

Since the measured value transmission system 550 is integrated with the small measuring device 501, in one mounting embodiment, the power supply (for example, a battery) of the small measuring device 501 supplies a part or all of the power required for transmitting the measured data. can do. Alternatively, in one implementation, a power generator is provided in the measured value transmission system 550 to supply the power required for wireless transmission so that the power of the main power supply of the small measuring device 501 is not consumed when the wireless transmission is started. You may. In each implementation, since the measurement value transmission system is integrated with the small measurement device 501, generally, any data holding operation (for example, measurement data) is performed by using the measurement value display 209 and the memory of the small measurement device 501. It is possible to store and display a fixed value of the above, and to notify the user when the measurement data is successfully transmitted). In another implementation, a separate indicator may be provided on the outer surface of a separate display or measurement transmission system 550.

FIG. 6 is a block diagram showing a measurement system 600 according to an exemplary embodiment, including circuit portions of a measurement value transmission system 650, a small measurement device 601 and a remote system 680. It should be appreciated that in each implementation, any or all of the circuit parts of FIG. 6 may represent each circuit part of each component of FIGS. 1-5. As shown in FIG. 6, the remote system 680 has a computer system 682, a signal processing unit 688, a transmission / reception circuit 690, and an antenna 681. The computer system 682 includes a measurement data application program execution unit 692, a status and / or control operation unit 694, and a data confirmation operation status / release operation unit 696. In each implementation, the computer system 682 can be a type of personal computing device such as a PC, tablet, or smartphone. As described above with reference to FIGS. 1-5, the remote system 680 can transmit and receive signals to and from the measured value transmission system 650 using the antenna 681. For example, the remote system 680 can receive the transmitted measurement data, and if the reception of the measured data is successful, the remote system 680 can return the “transmission successful” signal to the measured value transmission system 650. In order to realize transmission / reception operation, the transmission / reception circuit 690 includes various existing technologies (for example, a wireless USB transmitter using a wireless protocol such as Bluetooth®, another type of wireless protocol transmitter / receiver, etc.). Can be used.

In each mounting form, the signal processing unit 688 can be optionally provided. By converting the signal processing unit 688 into various formats or performing other functions, the signal received by the transmission / reception circuit 690 is converted from the raw state to a format suitable for processing by the measurement data application program execution unit 692. Can be converted. As an example, by using a protocol, the received raw measurement data can be converted into a measurement value that can be processed by the measurement data application program execution unit 692 (for example, for input to spreadsheet software). In one implementation, the signal processing unit 688 provides irrelevant information (for example, header information) (for example, information that is not input to the table calculation software, or measurement data application program execution unit) from the signal received by the transmission / reception circuit 690. Unnecessary irrelevant information to 692) is removed or processed in another way. Instead of providing the independent signal processing unit 688, the measurement data application program execution unit 692 may be configured to directly process the raw measurement data, ID, signal, etc. received by the transmission / reception circuit 690.

In each implementation, the manufacturer, the seller, and the like may design the measurement data application program execution unit 692 so that it can be used in one or more types of small measuring devices 601. In one implementation, the measurement data application program execution unit 692 includes a statistical processing control program for receiving measurement data from the small measurement device 601 and table calculation software or other program in which the measurement value indicated by the measurement data is input. And may have.

The status and / or control operation unit 694 determines and / or receives a signal from the measurement data application program execution unit 692 indicating the status of processing of the most recently received measurement data by another method. The data confirmation operation status / release operation unit 696 uses the determined status to transmit a confirmation signal and / or a release signal from the status and / or control operation unit 694 to the signal processing unit 688 at any time to transmit the measured value. Indicates whether it should be returned to 650. For example, as described above, in one implementation, if the transmitted measurement data is successfully received, the remote system 680 may return the transmission success signal to the measured value transmission system 650.

As also shown in FIG. 6, the measured value transmission system 650 includes a power generation / transmission activation unit 652, a power management circuit 654, a low power microcontroller / memory 656, small measurement device data and / or status / control. It has an operating unit 657, a controller routine execution unit 658, a low power transmission / reception circuit 660, and an antenna 661. In each implementation, each circuit component of the measured value transmission system 650 corresponds to each particular component of the measured value transmission system 150, 250, 350, 450 and / or 550. For example, in one implementation, the power generation / transmission activation unit 652 corresponds to the transmission activation unit TAP2 and the power generation unit EGP2 in FIGS. 2A and 2B. Further, the circuit units 654 to 658 correspond to the circuit element 253A, and the low power transmission / reception circuit 660 corresponds to the circuit element 253B of FIGS. 2A and 2B.

In each implementation, the power generation / transmission activation unit 652 may have one actuator (eg, actuator 255). Alternatively, the power generation / transmission activation unit 652 may have an actuator including a circuit unit dedicated to the power generation unit and an actuator including a circuit unit dedicated to the transmission activation unit. The power management circuit 654 adjusts the operation of the circuit unit of the measured value transmission system 650 according to the amount of power available. In each implementation, the power management circuit 654 realizes its function by utilizing various voltage regulation circuit elements and / or voltage detection circuit elements for monitoring the remaining amount of power. For example, in an embodiment as a specific example, the power management circuit 654 monitors the amount of available power when the power generation / transmission activation unit 652 starts operating, and the available power value sets a predetermined threshold value. If it falls below that, the low power microcontroller / memory 656 may be instructed to stop operation. If the low power microcontroller 656 continues to operate in a state where the power value is extremely low, an error may occur, but such a situation can be avoided by the above-mentioned function. Generally, the measured value transmission system 650 waits for a transmission success signal returned from the remote system 680 based on the limit of the amount of power generated by one operation cycle of the power generation / transmission activation unit 652. This limits the amount of time it can be active (eg, about 10 seconds or less in one specific and exemplary implementation).

In each implementation, the low power microcontroller / memory 656 operates as the central control unit of the measured value transmission system 650. In each embodiment, the low power microcontroller / memory 656 processes the measurement data from the small measuring device 601 (connected via a data port, connecting wiring, etc.), for example, in a format for transmitting the measurement data. It has functions such as conversion, adding an arbitrary command or identifier to the measurement data as appropriate, outputting the measurement data to the low power transmission / reception circuit 660, and transmitting the measurement data to the remote system 680. The small measuring device data and / or the status / control operation unit 657 is used to facilitate communication between the small measuring device 601 and the low power microcontroller / memory 656. For example, when a data retention function is required, the small measuring device data and / or status / control operation unit 657 determines an appropriate control signal and transmits this signal to the small measuring device processing / control unit 612. It can be used to initiate the data retention function.

The low power microcontroller / memory 656 also collaborates with the controller routine execution unit 658 to perform various operations. The controller routine execution unit 658 includes an actuator operation unit 671, a hold / queue operation unit 672, a transmission operation unit 674, a signal reception operation unit 676, and an ID link operation unit 678. In each implementation, the actuator operating unit 671 determines when the user has operated the actuator and / or determines various state-dependent operations, as described above with reference to FIGS. 1-5. Used. For example, in one exemplary implementation, when the actuator is operated the first time, it starts the holding operation, and then when it is operated the second time, it starts the transmitting operation, which is the actuator operating unit 671. Realized by.

The retention / queue operation unit 672 is used to realize various data retention functions. For example, the retention / cue operation unit 672 stores measurement data in the low power microcontroller / memory 656 when the user operates the data retention actuator, and / or transmits a command to the small measurement equipment processing / control unit 612. Therefore, the measurement data can be stored as a part of the holding operation in the small measuring device 601. As another example of operation of the retention / queue operation unit 672, when performing a data retention release operation (for example, as a result of receiving a transmission success signal from the remote system 680), the low power microcontroller / memory 656 is a small measuring device. A signal may be transmitted to the processing / control unit 612 to terminate the data holding state.

Further, the transmission operation unit 674 adds a serial number (serial number) to the measurement data, adds additional information (for example, device ID, etc.) to the measurement data, and / or converts the measurement data into various formats. It is used to convert or add a command to assist the operation of the measurement data application program execution unit 692 of the remote system 680 to the measurement data. As a specific example, when the measurement data application program execution unit 692 inputs the measurement data to the spreadsheet software, the transmission operation unit 674 may add an "enter" command to the end of the measurement data being transmitted. As a result, when the input of the measurement data being transmitted is completed in the spreadsheet application software, the user moves to the next cell according to the "enter" command. The measurement data to be received next time will be input to this destination cell.

Further, the signal receiving operation unit 676 is used in each implementation form to process a signal received from the remote system 680 or another system. For example, as described above, in one implementation, the remote system 680 returns the transmission success signal to the measured value transmission system 650 when the measurement data is successfully received. The signal receiving operation unit 676 can decode or otherwise process the format of such a signal received from the remote system 680. Further, according to one implementation embodiment, when the measured value transmission system 650 needs to switch between the transmission mode and the reception mode, the signal reception operation unit 676 determines the timing for activating the transmission mode and the reception mode. Assist the adjustment process.

Further, the ID link operation unit 678 determines the model of the device that is the source of the measurement data by the remote system 680, and / or determines the device that is the source of the measurement data when a plurality of devices exist. It is used to add the necessary information to the measurement data to be transmitted. For example, a plurality of small measuring devices may transmit measurement data to one remote system 680 within a predetermined period. In this case, it is desirable that the remote system 680 can determine, among the plurality of small measuring devices, the small measuring device that is the source of the currently received set of measurement data. Further, various models of small measuring devices (for example, different models of calipers, measuring devices (gauge), etc.) may be able to transmit measurement data. In this case, since the remote system 680 interprets or processes the measurement data in different ways depending on the model, it is necessary to appropriately identify these small measuring devices.

As will be appreciated by those skilled in the art, the various exemplary circuitry of the measurement system 600 will typically consist of or be implemented in any type of computing system or device. Can be done. Such computing systems or devices may have one or more processors running software that implements the functions described herein. These processors may include programmable general purpose or dedicated microprocessors, programmable controllers, application specific integrated circuits (ASICs), programmable logic devices (PLDs) and the like, or combinations thereof. The software can be stored in a memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, or a combination thereof. The software can also be stored in one or more storage devices such as magnetic disks or optical discs, flash memory devices, or any other type of non-volatile storage medium for storing data. The software has one or more program modules, the routines, programs, objects, components, data structures in which the one or more program modules perform specific tasks or realize specific abstract data types. Etc. may be included. In a distributed computing environment, the functionality of program modules may be combined or distributed across multiple computing systems or devices to be accessed via service calls in either wired or wireless configurations. ..

The problem-solving and related principles described below with reference to FIGS. 7-10 differ from the problem-solving and related principles described above with reference to FIGS. 1-6. The various combinations of elements, principles and operations described above with reference to FIGS. 1-6 can be used in different implementations of the measured value transmission module. The measured value transmission module can be connected to a battery-powered portable measuring device. The measured value transmission module uses the power generated by the user (mostly the power generated by the user or only the power generated by the user), and obtains the measured data from the portable measuring device. It can be transmitted wirelessly to a remote data node. In particular, the user may activate a small mechanical energy generator provided in the module (eg, also as a user pressing a button as a trigger to transmit measurement data). This eliminates the need to use battery power from a battery-powered portable measuring device to wirelessly transmit data.

However, according to the technique described above, although it is possible to wirelessly transmit data without consuming the battery resources of the battery-powered portable measuring device, it is necessary for the user to manually operate the data. Therefore, there is a problem that the practicality of the measured value transmission module is limited.

Ideally, the wireless transmission module should be compatible with as many types of battery-powered portable measuring devices as possible in order to achieve high practicality and value. Some battery-powered portable measuring devices are not small. The power generation actuator disclosed above is not practical for non-compact battery-powered portable measuring devices. For example, battery-powered position measuring scales used as follows are also known. That is, the battery-powered caliper reading head and the scale member are mounted on a drilling machine or a lathe, and the displacement of the machine itself (a drilling machine or a lathe or the like) is measured and displayed. In some cases, it is desirable to attach such a measuring scale member to the bottom or back of the machine itself (such as a drilling machine or lathe) and constantly send the measurements to a "remote" display that can be placed anywhere. Sometimes. In this case, the wireless transmission module that requires pressing the button is not practical. Conversely, existing battery-powered (or wired-powered) wireless transmission attachments that provide an interface to connect to such scales and are installed in inconvenient locations are large, bulky, and cumbersome to replace batteries. Or, it is necessary to permanently install power wiring in an inconvenient installation location. Moreover, such existing data transmission devices are ergonomically difficult to handle and are not easy for anyone to use when attached to a small battery-powered portable measuring device.

Of course, there are a certain number of users who are reluctant to replace the battery in the battery-powered portable measuring device. Today, many such devices can operate for several years with a small button cell or coin cell type battery less than 12 millimeters in diameter. It is desirable to extend battery life. Devices that run out of battery are often not used (like watches, etc.). Similarly, there may be users who are reluctant to replace the battery in the desired wireless data transmission module.

In view of the above circumstances, it is, of course, desirable that the wireless data transmission module operate and continuously supply measurement data without the need for battery power or manual operation. The wireless data transmission module should be capable of responding to remote requests for measurement data from remote data nodes. Along with / instead of this, when the remote data node is in the vicinity of the radio data transmission module, the radio data transmission module simply (regardless of the remote request) transmits the measurement data automatically or semi-automatically. Is desirable. It is desirable that the wireless data transmission module be compact, lightweight, ergonomically easy to use, and easy to use after being attached to various small battery-powered portable measuring devices. At the same time, it is desirable that the wireless data transmission module be installed in an inconvenient location and be able to operate with a battery-powered measuring device mounted on the machine itself (such as a drilling machine or lathe). The wireless data transmission module should operate over a convenient distance from the remote data node. Since the user may accidentally disturb the measurement position of the measuring device, it is desirable to activate or transmit the measured value without inadvertently changing the position of the hand or pressing a button.

All of the desirable features outlined above are realized by the combination of features of the systems and related principles according to the various implementations described below with reference to FIGS. 7-10. The data transmission module uses power generated by power generation (power harvesting / energy harvesting; hereinafter simply referred to as power generation) (mostly by power generation or by power generation only) and / or by using power wirelessly supplied from a remote data node. , Inputs measurement data from a battery-powered portable measuring device and wirelessly transmits the corresponding measurement data signal to a remote data node. The data transmission module does not use the power from the battery of the battery-powered portable measuring device when inputting measurement data and wirelessly transmitting the measurement data signal to the remote data node. In general, existing general purpose wireless power generation and data communication solutions are large and / or power intensive. For this reason, existing solutions are undesirable or unacceptable for use as an option or "embedding" in existing small battery-powered portable measuring devices. Some existing wireless power generation and data communication solutions used in medical treatment are small enough, but the power generation range is insufficient and inconvenient. The wireless data transmission module according to each implementation form disclosed below solves such a problem.

FIG. 7 is a diagram showing a data transmission module 750 according to the seventh exemplary implementation. In the figure, the data transmission module 750 is connected to the battery-powered portable measuring device 701 and works in a work area WA (for example, a measurement station work surface or desk, or an area of the size of an industrial work “work cell” or the like). The measurement data TMD1 is wirelessly transmitted from the battery-powered portable measuring device 701 to the remote data node 780 over the distance WD. In each implementation form, it can be said that the wireless device in the work area WA is included in the "personal measurement network". The measurement data TMD1 to be transmitted may be related to one or more measured values (for example, the measurement dimension MD1) of the workpiece WP acquired by the battery-powered portable measuring device 701. The remote data node 780 may have a field generation / reception unit 781 and a remote device interface / circuit unit 770. The field generation / reception unit 781 is connected to the generation / reception circuit 790. The remote device interface / circuit unit 770 may have various operating circuits and routines 782 and a user interface 795.

In one implementation, the user interface 795 may include a measured value display 795A, a touch screen 795B, and the like. The touch screen 795B displays text and / or control elements. The operating circuit and routine 782 may be realized by a processor and a memory. As a result, various operations outlined with reference to the measurement data application program execution unit 692 realized by the computer system 682 of FIG. 6, the status and / or control operation unit 694, and the data confirmation operation status / release operation unit 696. The same operation as is realized. Along with / in place of this, other actions described herein or other desired actions are realized.

The field generation / reception unit 781 and the generation / reception circuit 790 will be described in detail later with reference to FIGS. 8A to 8C. Generally, the field generation / reception unit 781 and the generation / reception circuit 790 generate at least one energy supply field STS1 (for example, to power the data transmission module) and wirelessly receive the measurement data signal from the data transmission module 750. It is configured to do.

The measurement data from the battery-powered portable measuring device 701 may be displayed as the display measured value DM1 on the user interface (for example, the display) 795 of the built-in display 709 of the battery-powered portable measuring device 701 and / or the remote data node 780.

In each implementation, the data transmission module 750 is a battery-free accessory and may be an attachment attached to the battery-powered portable measuring device 701. In each implementation, the data transmission module 750 has a main body (details will be described later), a field reception / radio data generation unit 761, and a data transmission / energy management circuit 760. The field reception / radio data generation unit 761 and the data transmission / energy management circuit 760 will be described in detail later with reference to FIGS. 8A to 8C. The main body is configured to be physically connected to the battery-powered portable measuring device 701. The field reception / radio data generation unit 761 is configured to receive the energy supply field STS1 from the remote data node 780. Generally, the field reception / radio data generation unit 761 may be connected to the transmission circuit included in the data transmission / energy management circuit 760. As a result, the measurement data signal can be wirelessly transmitted to the remote data node 780 (details will be described later). The data transmission / energy management circuit 760 has a data connector. The data connector of the data transmission / energy management circuit 760 is configured to be connected to the data connector of the battery-powered portable measuring device 701. The measurement data from the battery-powered portable measuring device 701 may be input to the data transmission / energy management circuit 760 via the data connector. The data transmission / energy management circuit 760 may wirelessly transmit the measurement data signal TMD1 corresponding to the input measurement data to the remote data node 780 using the field reception / radio data generation unit 761.

In each mounting embodiment, the battery-powered portable measuring device 701 may be supplied with electric power from the battery. However, this battery is not part of the data transmission module 750 and is not connected to the data transmission module 750 for power supply. That is, the battery-powered portable measuring device 701 is driven by a battery independent of the data transmission module 750. This "independent battery" is configured to display and operate measurement data on the built-in display 709 regardless of whether the battery-powered portable measuring device 701 is connected to the data transmission module 750. In each embodiment, when the field reception / wireless data generation unit 761 wirelessly transmits the measurement data signal to the remote data node 780, the following a), b) or c), that is, a) the generated energy.
b) Modulated reflection of the energy supply field STS1 received from the remote data node 780, or coupling with the energy supply field STS1 received from the remote data node 780, or c) configured to use only the combination of a) and b). Will be done. These details will be described later.

In each implementation, various protocols and commands related to holding, transmitting and receiving measurement data may be realized as outlined in this paper, or may be realized according to a known method in some cases. ..

In each implementation, the system outlined above may be configured to use a relatively small and ergonomically practical field receive / radio data generator 761. If the battery-powered portable measuring device 701 and the data transmission module 750 are relatively close to the remote data node 780 (eg, within a typically used work area WA, a working distance of about 1 to 2 meters), the data Sufficient power (eg, about 10 microwatts, etc.) can be provided to the transmit module 750. This system may operate according to the various principles disclosed in this paper. Hereinafter, effective components and techniques for energy power generation and data transmission will be described.

8A-8C are block diagrams showing various forms of energy supply field coupling and data transmission between the data transmission modules 850A-850C and the remote data nodes 880A-880C according to an exemplary implementation. ..

FIG. 8A shows a remote data node 880A and a data transmission module 850A. Of course, the component with the specific reference code in FIG. 8A is the component with the same reference code in FIG. 7 (eg, components suffixed with the same number "XX", such as 7XX and 8XX). Corresponding and / or operating in the same manner may be used, and unless otherwise specified, it may be generally understood by analogy.

The remote data node 880A has a field generation / reception unit 881A. The field generation / reception unit 881A is connected to the generation / reception circuit 890A. The generation / reception circuit 890A is connected to the processor 888A. The processor 888A is connected to the remote device interface / circuit unit 870A. The data transmission module 850A has a field reception / radio data generation unit 861A. The field reception / radio data generation unit 861A is connected to the data transmission / energy management circuit 860A.

In the embodiment shown in FIG. 8A, the field generation / reception unit 881A and the field reception / radio data generation unit 861A may be electric loop antennas. The energy supply field (indicated by the power transmission P1) generated by the field generation / reception unit 881A may be a oscillating magnetic field. The vibrating magnetic field is dielectrically coupled to the field reception / radio data generation unit 861A (the field reception / radio data generation unit 861A receives the vibration magnetic field). Such inductive coupling may be realized according to a known method. For example, known RFID system technology (see, eg, http://rfid-handbook.de/about-rfid.html.).

In each implementation, the field generation / reception unit 881A connected to the matching circuit 891A and the field reception / radio data generation unit 861A connected to the matching circuit 863A are resonantly formed as part of the resonant inductive coupling configuration. It may have a circuit. The resonant inductively coupled configuration may be realized according to a known principle. For example, various electric loop antennas and impedance matching and / or resonant circuits useful for matching circuits 863A and 891A may be implemented according to the principles disclosed in Patent Documents 6 to 10. Such resonant inductive coupling can significantly increase coupling and power transfer (eg, about 10 to 1000 times in each implementation) as compared to configurations without resonant inductive coupling. In the illustrated implementation, the generation / reception circuit 890A of the remote data node 880A has a matching circuit 891A, a supply / transmission circuit 894A, and a reception circuit 893A. These circuits may be realized according to a known principle. For example, since it is described in the patent document, it is simply explained briefly in this paper.

In short, the matching circuit 891A may be configured to provide the desired impedance and / or to tune the resonant frequency of the field generation / receiver 881A. The supply / transmission circuit 894A and the reception circuit 893A may be connected to the field generation / reception unit 881A via the matching circuit 891A. The supply / transmission circuit 894A is configured to drive a vibrating magnetic field (eg, at a resonant frequency to transmit power P1). The vibrating magnetic field may be dielectrically coupled to the field reception / radio data generation unit 861A (the field reception / radio data generation unit 861A receives the vibrating magnetic field). Although the details will be described later, in the data transmission / energy management circuit 860A, since the data transmission module 850A transmits data (see MLOAD2 in FIG. 8A), the impedance (or load) of the field reception / radio data generation unit 861A should be modulated. Just do it. The receiving circuit 893A may detect the modulation impedance MLOAD2 of the field generation / receiving unit 881A. Briefly, the field reception / radio data generation unit 861A dielectrically applies a load to the oscillating magnetic field (extracts energy from the oscillating magnetic field). The receiving circuit 893A may monitor the modulation load impedance. For example, as schematically shown in FIG. 8A, the modulation load impedance is monitored by monitoring the voltage drop in the internal resistance of the circuit driving the field generation / receiver 881A. In one known implementation, the receiving circuit 893A may demodulate the AC voltage at the monitored internal resistance and detect fluctuations in the demodulated signal constituting the transmitted data.

In the implementation schematically shown in FIG. 8A, the supply / transmission circuit 894A may be controlled by the processor 888A and configured to modulate the drive amplitude of the oscillating magnetic field in order to transmit data. The reception circuit 867A of the data transmission / energy management circuit 860A may detect the modulation amplitude of the vibration magnetic field received by the field reception / radio data generation unit 861A (details will be described later).

As inferred from the remote device interface / circuit section 770 described above, the remote device interface / circuit section 870A may have similar components that may be realized in cooperation with the processor 888A.

In the illustrated embodiment, the data transmission / energy management circuit 860A of the data transmission module 850A includes a matching circuit 863A, a power generation circuit 864A, a reception circuit 867A, an energy storage device 862A, a processor / memory 866A, and a data connector 868A. And a transmission circuit 865A. These circuits may be realized according to a known principle. For example, since it is described in the patent document, it is simply explained briefly in this paper.

In short, the matching circuit 863A may be configured to provide the desired impedance and / or tune the resonant frequency of the field reception / radio data generator 861A according to the principles outlined above. The power generation circuit 864A and the reception circuit 867A may be connected to the field reception / radio data generation unit 861A via the matching circuit 891A. The power generation circuit 864A is configured to rectify and boost the voltage obtained from the current of the field reception / radio data generation unit 861A by the vibration magnetic field (see, for example, Patent Document). The energy storage device 862A (eg, a supercapacitor or the like) is connected to the power generation circuit 864A, charged with the output voltage of the power generation circuit 864A, and supplies power to various components of the data transmission module 850A.

In the embodiment shown schematically in FIG. 8A, the transmission circuit 865A modulates the impedance (or load) of the field reception / radio data generation unit 861A because the data transmission module 850A transmits data (see MLOAD2 in FIG. 8A). do it. In one implementation, the processor / memory may receive measurement data from the battery-powered portable measuring device 701 via the data connector 868A. The processor / memory may act on the transmit circuit 865A to modulate the impedance of the field receive / radio data generator 861A in order to transmit the measurement data (see, for example, the receive circuit 893A of the remote data node 880A). According to the principle outlined in). In one embodiment, as schematically shown in FIG. 8A, the transmit circuit 865A uses a processor controlled transistor to change (eg, short) the internal impedance of the field receive / radio data generator 861A. Modulates the impedance of.

When the remote data node 880A operates to modulate the drive amplitude of the oscillating magnetic field to transmit data, the receiving circuit 867A derives the modulation amplitude derived, for example, by monitoring the voltage drop at the test resistance of the receiving circuit 867A. May be monitored. In one known implementation, the receiving circuit 867A may demodulate the AC voltage monitored by the test resistor and detect fluctuations in the demodulated signal constituting the transmission data.

As illustrated or suggested in this paper, the processor / memory 866A may transmit and receive various signals and be connected so as to operate as outlined in this paper. The processor / memory 866A may include the module circuit / operation unit 858A or may be connected to the module circuit / operation unit 858A in order to realize the related operation. As outlined with reference to FIG. 6, the module circuit / operation unit 858A includes an actuator operation unit 671 realized by the controller routine execution unit 658, a hold / queue operation unit 672, a transmission operation unit 674, and a signal reception operation. It suffices to have a circuit or routine useful for realizing various operations similar to the various operations outlined with reference to the unit 676 and the ID link operation unit 678.

FIG. 8B shows a remote data node 880B and a data transmission module 850B. Of course, the components with the specific reference numerals in FIG. 8B may correspond to and / or operate in the same manner as the components with the same reference numerals in FIG. 8A, and in general, unless otherwise specified. It should be understood by analogy. Therefore, in the following discussion, only the important differences will be emphasized. The remote data node 880B has a field generation / reception unit 891B'. The field generation / reception unit 891B'is connected to the generation / reception circuit 890B. The data transmission module 850B has a field reception / radio data generation unit 861B. The field reception / radio data generation unit 861B is connected to the data transmission / energy management circuit 860B.

In the embodiment shown in FIG. 8B, the field generation / reception unit 891B'and the field reception / radio data generation unit 861B may be RF antennas (eg, metal “tag” antennas, dipole antennas, strip antennas used in RFID components). etc). Generally, the size of the field generator / receiver 891B'is not limited. In general, the antenna of the field receiving / receiving unit 891B'may be of any design for the purpose of transmitting a desired level of power to the field receiving / radio data generating unit 861B. On the other hand, it is desirable that the field reception / wireless data generation unit 861B is relatively compact and compatible with the ergonomic design of the data transmission module 850B. In each implementation, the energy supply field (indicated by power transmission P1) generated by the field generation / receiver 891B'may include the desired RF and / or UHF frequency of electromagnetic radiation. The field reception / radio data generation unit 861B receives electromagnetic radiation. Such a bond may be realized according to a known method. For example, known RFID system technology (see, eg, http://rfid-handbook.de/about-rfid.html.). Various suitable antennas and related circuits described later may be carried out according to the principles disclosed in the above-mentioned Patent Documents, Patent Documents 11 to 13 and, for example, Non-Patent Documents 1 to 2.

As outlined, the generation / reception circuit 890B of the remote data node 880B differs from the generation / reception circuit 890A in that it uses an RF antenna. The generation / reception circuit 890B has a circuit similar to the circuit of the generation / reception circuit 890A and a directional coupler 892B. The directional coupler 892B connects the receiving circuit 893B and the supply / transmitting circuit 894B and the field generation / receiving unit 891B'via the matching circuit 891B (this is an option depending on the mounting form). These circuits may be realized according to a known principle. For example, since it is described in the patent document, it is simply explained briefly in this paper.

The supply / transmission circuit 894B drives a field generation / receiver 891B'via a directional coupler 892B to generate a radial field (eg, to transmit power P1). The field reception / radio data generation unit 861B may receive a radial field. Although the details will be described later, in the data transmission / energy management circuit 860B, since the data transmission module 850B transmits data (see MP2 in FIG. 8B), the impedance of the field reception / radio data generation unit 861B may be modulated. The receiving circuit 893B may detect the impedance modulation. Briefly, according to the known principle of backscatter coupling, the impedance modulation affects (modulates) the reflected power MP2 received by the field generation / receiver 891B'. Depending on the implementation, the field reception / radio data generation unit 861B and the matching circuit 863B may be configured to resonate with the radial wavefront from the field generation / reception unit 891B'. This gives a relatively large reflective cross section. The receiving circuit 893A may monitor the reflected power MP2 via the directional coupler 892B according to a known method. For example, the "radar equation" and known circuit techniques can be used to estimate the ratio of the power P1 transmitted by the field generator / receiver 891B'to the reflected power MP2. This change in ratio constitutes the transmitted data.

Generally, the other components of FIG. 8B are understood to behave similarly to the corresponding components of FIG. 8A and may be understood based on the above description. It will be recognized by those skilled in the art and / or based on patent literature etc. that modifications are required for conformance.

FIG. 8C shows a remote data node 880C and a data transmission module 850C. Of course, the components with the specific reference numerals in FIG. 8C may correspond to and / or behave similarly to the components with the same reference numerals in FIGS. 8A and / or 8B, with particular disclaimer. Unless otherwise, it should generally be understood by analogy. Therefore, in the following discussion, only the important differences will be emphasized. The remote data node 880C has a field generation unit 881C and a field reception unit 881C'. The field generation unit 881C and the field reception unit 881C'are connected to the generation / reception circuit 890C. The data transmission module 850C has a field reception unit 861C and a radio data generation unit 861C'. The field receiving unit 861C and the radio data generation unit 861C'are connected to the data transmission / energy management circuit 860C.

In the embodiment shown in FIG. 8C, the field generation unit 881C and the field reception unit 861C may be electric loops. The accompanying components and actions may be inferred from FIG. 8A. However, in the data transmission module 850C of this embodiment, the field generation unit 881C and the field reception unit 861C are used only for the purpose of energy transmission and power generation. Therefore, the receiving circuit is not included in this. The field receiving unit 881C'and the radio data generation unit 861C' may be RF or UHF antennas. Data may be transmitted between the field receiving unit 881C'and the wireless data generating unit 861C' using only the generated power and / or the stored energy from the energy storage device 852C by a known method. The system implementation of FIG. 8C can be useful, for example, to constantly display the measured values from the data transmission module 850C and the mounted measuring device.

Of course, in the system configuration of FIG. 8C, the components 880Ct and 880Cr may be physically separated (for example, by the dotted line DL of the remote data node 780 of FIG. 7). Depending on the mounting mode, the components 880Ct and 880Cr may be separate power supplies. Alternatively, depending on another implementation, the components 880Ct and 880Cr may be connected by power and signal connections. In either case, for convenience and / or for better wireless connection when there are obstacles around, the components 880Ct and 880Cr are the work area (eg, the work area WA in FIG. 7). ) May be placed individually.

FIG. 9A is a perspective view partially schematically and partially schematically showing the data transmission module 950 according to the seventh exemplary implementation. The data transmission module 950 is connected to a battery-powered portable measuring device 901 that wirelessly transmits measurement data to a remote data node (for example, the remote data node 780 in FIG. 7). Of course, the components with the specific reference numerals in FIG. 9A may correspond to and / or operate in the same manner as the components with the same reference numerals in FIGS. 7, 8A-8C and 4. Unless otherwise specified, it should generally be understood by analogy. Therefore, in the following discussion, only the important differences will be emphasized. The data transmission module 950 has a main body BP9, a circuit board assembly 951 provided inside the main body BP9 (indicated by a dotted line), and a cover BP9'. As shown, the main body BP9 has a typical coupling mechanism CF9 (any known mechanical coupling mechanism (not shown)). The coupling mechanism CF9 may be mechanically connected to the meshing mechanism of the slider 206 according to the principle outlined above. As a result, the data transmission module 950 is fixed to the battery-powered portable measuring device 901. The area BP9cp of the main body portion BP9 may be a connector area. The dimensions and connection mechanism of the area BP9cp (connector area) of the main body BP9 may be the same as or the same as the corresponding mechanism of the main body BP4 of the module MTM4 of FIG. The following outline is applicable to both. The size and shape of the main body BP9 differ to some extent from the size and shape of the main body BP4 of FIG. This is because the main body unit BP9 has a main purpose of having a large capacity in order to accommodate a relatively large field reception / radio data generation unit 961. However, the functions are similar. The purpose of the relatively large field receive / radio data generator 961 is to transmit a larger amount of power from a remote data node (eg, the remote data node 780 in FIG. 7) to generate a larger amount of energy. In general, the larger the field reception / radio data generation unit 961, the larger the amount of electric power can be transmitted and the larger amount of energy can be generated. However, in implementations configured to generate electricity very efficiently and / or designed to operate for short working distance WDs (see WD in FIG. 7), relatively large fields. The reception / wireless data generation unit 961 and the circuit board assembly 951 may be suitable for use in a main body unit having the same size as the main body unit BP4, if necessary.

In each mounting form shown in FIG. 9A and the like, ergonomically, the shape of the main body portion is the main body of the portion (for example, the slider (reading head) 206) to which the main body portion is connected, as in the main body portion BP9 of FIG. 9A. It is desirable that the shape is similar to that of. In each embodiment, when the main body BP9 of the data transmission module 950 is physically connected to the battery-powered portable measuring device 901, most of the volume of the data transmission module 950 is located at the rear of the battery-powered portable measuring device 901. (For example, the rear part of the battery-powered portable measuring device 901 is opposite to the built-in display 909 or the like provided in the front part of the battery-powered portable measuring device 901). In addition, the relatively large field receive / wireless data generator 961 is located within the capacity of the rear of the battery-powered portable measuring device 901 when the data transmission module 950 is physically connected to the battery-powered portable measuring device 901. do it. In each mounting embodiment, when the circuit board assembly 951 having the relatively large field reception / wireless data generation unit 961 is mounted on the main body unit BP9, the circuit board assembly 951 and the rear portion of the battery-powered portable measuring device 901 are A desired interval Dsep may intervene. This allows for more efficient reception of energy supply fields from remote data nodes in general, especially when the rear of the battery-powered portable measuring device 901 is made of metal. Similar considerations are mentioned in some patent literature. Depending on the mounting configuration, the spacing Dsep may be at least 2 mm or 4 mm or more due to constraints for ergonomically designing the body BP9.

As shown in FIG. 9A, depending on the implementation, the data transmission module 950 may optionally have a low power actuator 955'and / or a power generation indicator 959'. In contrast to the actuator 455, the low power actuator 955'does not generate energy and consumes significantly less energy. However, in other respects, the operation and protocol of the low power actuator 955'is similar to the operation and protocol for the actuator disclosed above in this paper. Similarly, the power generation indicator 959'consumes significantly less energy. The power generation indicator 959'may indicate to the user whether power generation and / or energy storage is the operating level of the data transmission module 950 (eg, whether the device is within or out of the working distance WD with respect to the remote data node). Is there).

The illustrated circuit board assembly 951 includes a relatively large field receive / radio data generator 961. The relatively large field reception / radio data generation unit 961 is connected to the data transmission / energy management circuit 960. The data transmission / energy management circuit 960 incorporates a module circuit / operation unit 958 to realize related operations (all operations are outlined above with reference to the corresponding components of FIGS. 8A-8C). You may. The illustrated data transmission / energy management circuit 960 further comprises a data connector element 968'. At the time of attachment, the data connector element 968'is connected and / or coupled with the data connector 968 in the connector region BP9cp of the main body BP9 by a known method. Generally, the configuration of the data transmission modules 850A to 850C realized by the data transmission module 950 may be any of various configurations. Of course, the data transmission module 950 according to the above-described implementation embodiment shown is merely an example, and is not limited thereto. More generally, the data transmission module may realize any combination of various mechanisms or configurations of the data transmission modules 850A to 850C, and may be any combination that can be operated as desired. Various known manufacturing methods and assembly methods may be used according to the principles disclosed in this paper.

FIG. 9B is a perspective view partially schematically and partially schematically showing the data transmission module 950B according to the seventh exemplary implementation. Of course, the components with the specific reference numerals in FIG. 9B may correspond to and / or operate in the same manner as the components with the same reference numerals in FIG. 9A, and in general, unless otherwise specified. It should be understood by analogy. Therefore, in the following discussion, only the important differences will be emphasized.

The data transmission module 950B has a main body portion BP9'. The main body portion BP9'may accommodate the circuit board assembly 951B by a known method (unlike the main body portion BP9). Unlike the circuit board assembly 951 of FIG. 9A, the circuit board assembly 951B may be any known type of "rigid flexible" assembly and has one or more tabs 951a-951d. Each tab unit may accommodate one or more corresponding additional field reception / radio data generation units 961a to 961d. The tab portion may be bent about 90 degrees with respect to the main body portion BP9'before being assembled to the main body portion BP9'. The additional field reception / radio data generation units 961a to 961d may each have an appropriate matching circuit (for example, any of the matching circuits 863A to 863C described above). The matching circuit may be incorporated in the data transmission / energy management circuit 960B by a known method (for example, the method disclosed in the patent document).

In the configuration of FIG. 9B, more power is transmitted from the remote data node (for example, the remote data node 780 in FIG. 7) by having the field reception area added by the additional field reception / radio data generation units 961a to 961d. It can be advantageous in that energy power generation can be realized. By arranging various field reception / radio data generation units 961 and 961a to 961d three-dimensionally, there is a possibility of increasing power generation in an unexpected operation direction.

As shown above with reference to FIG. 9A, it is configured to generate electricity very efficiently and / or designed to operate for short working distances WD (see WD of FIG. 7). In the above-mentioned mounting form, the relatively large field reception / wireless data generation unit 961 and the circuit board assembly 951 are made suitable for use in the main body unit having the same size as the main body unit BP4, if necessary. May be good. By adopting the configuration of the additional field reception area and the three-dimensional arrangement shown in FIG. 9B, it is advantageous to adapt the configuration to the main body portion having the same size as the main body portion BP4.

At block 1020, a communication connection is established between the data transmission module and the remote data node. In each implementation, the remote data node may start establishing a communication connection by receiving a predetermined amount of energy generated by the data transmission module. For example, the data transmission module may initially be inactive if it is not within a certain distance (eg, 1 meter, etc.) from the remote data node. When the data transmission module enters the above-mentioned specific distance, it may execute the function for "wake-up" and become active. The data transmission module receives the reception from the remote data node and starts generating energy. In this process, the data transmission module may establish a communication connection when it detects that it has entered within a specific distance. In addition to / instead of this, the data transmission module may establish a communication connection when it detects that it has received energy from a remote data node. In each implementation, a communication connection may be established by transmitting a specific type of communication connection code and / or measurement data and the like.

At block 1030, measurement data is input to the data transmission module from the battery-powered portable measuring device via the data connector. At block 1040, the data transmission module wirelessly transmits the measurement data signal corresponding to the input measurement data to the remote data node by using the radio data generation unit.

In each implementation, the wireless data generator may be configured to use only or mainly use (a), (b) or (c) when wirelessly transmitting the measurement data signal to the remote data node. ..
