Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a control device (hereinafter referred to as a control device).
The present invention relates to an automatic measurement system in which a plurality of measuring instruments are connected by a communication line and a controller controls each measuring instrument to automatically perform various measurements. In addition, the present invention particularly relates to an automatic measurement system capable of performing automatic measurement by controlling a measuring instrument installed at a distant point from a place where a user is.

[0002]

[Prior art]

[First Prior Art] As the above-described automatic measurement system, the following configuration has conventionally been used. That is, the GPIB between the controller and the measuring instrument
(General Purpose Interface Bus) and RS-232C interface cables.
C (Beginner's All-purpose Symbolic Instruction Co
By using a programming language such as de) or by combining control commands unique to each measuring instrument, a control program for controlling the measuring instrument from the controller is created.
Then, by executing the created control program on the controller side, each measuring device is controlled to perform automatic measurement. However, the maximum cable length of GPIB is limited to 20 m, and the maximum cable length of RS-232C is also limited to 15 m. Therefore, when it became necessary to control the measuring instrument from a remote place, an automatic measuring system employing these standards could not be used.

[Second Prior Art] In order to avoid such a problem, GPIB or RS using an optical fiber or the like is used.
There are also products on the market that extend the cable length of -232C substantially, but the use of such products requires the laying of an optical fiber or the like, which easily meets the demand for controlling the measuring instrument from a distance. It was difficult. When constructing the above-mentioned automatic measurement system,
Since a person who constructs the system (a so-called system engineer) needs at least the ability to create the above-described control program, not everyone can easily construct the system.

[0004] Furthermore, since the part related to the detailed operation of the measuring instrument in the control program is composed of a combination of control commands for the measuring instrument, if the control command is different for each measuring instrument, the handling of each measuring instrument will be considered. It was necessary to read the instruction manual and fully understand the control commands before starting to create the control program, and even a person having the ability to create a program could not easily create a control program. In addition, even if a control program is created, it is difficult to divert the control program to a system using another measuring instrument because the control command is different for each measuring instrument. Therefore, in many cases, the modification of the control program in accordance with the system change requires an effort close to creating a new control program.

[Third Prior Art] In order to avoid such a problem, a large number of programs related to the detailed operation of each measuring instrument are prepared for each measuring instrument in advance as a library of control program modules dedicated to each measuring instrument. Measurement control software which creates a control program by combining these has been developed and is already sold. This measurement control software is used as described below. That is, the system engineer installs a library of control program modules and measurement control software in the controller in advance. When a control program is created, a required control program module is selected from a library, and the selected control program module is combined with a control program body that controls the operation of the entire system. By doing so, it is possible to easily create a control program without having to understand the control commands of each measuring device, as long as there is only a rudimentary program creation ability, and the labor for creating a control program is greatly reduced.

As described above, in a system using measurement control software, the preparation of a control program is simplified by preparing control program modules corresponding to various measuring instruments in the controller in advance. Therefore, for the convenience of the user (system engineer),
It is necessary to prepare a large number of control program modules in the controller as a library that can support more measuring instruments (that is, all measuring instruments that may be connected to the controller). This means that a control program module library corresponding to a measuring instrument that is not connected at this time but has been connected in the past or a measuring instrument that may be connected in the future is installed in the storage device in the controller. Will be invited. In other words, in such a system, the controller requires a large-capacity storage device, and accordingly, there is a disadvantage that the controller is also expensive.

Of course, if only the control program module corresponding to the currently connected measuring instrument is installed in the controller, the storage capacity required on the controller side can be reduced. However, in this case, every time a new measuring instrument is connected, the control program module of the added measuring instrument must be installed in the controller, which is extremely inconvenient. Further, there is a possibility that an accident such as loss of a storage medium such as a CD-ROM (compact disk-read only memory) storing the control program module may occur.

On the other hand, among measuring instruments, there are many new products that have just been released and special products that are used only in very limited fields, and control program modules for all these measuring instruments are provided. Is not prepared for the measurement control software described above. Therefore, when using a measuring instrument for which such a control program module is not prepared in advance, a system engineer must create a control program by himself. Therefore, in such a case, the same problem as before the appearance of the measurement control software occurs.

[0009]

In order to avoid the various problems described above, the present inventor connects the controller and the measuring instrument with a communication line, and installs a control program module to be executed by the controller in advance on the measuring instrument side. Built in
When using an automatic measurement system, an automatic measurement system has been proposed in which a control program module is read from a measuring instrument to a controller side and executed (Japanese Patent Application No. 9-97).
No. 26). The present invention is excellent in that the various problems described above can be solved. However, there is a problem when using a network such as a LAN (local area network) or the Internet as a communication line. In other words, these networks are used by being connected to systems other than the automatic measurement system,
When the network becomes congested, the delay time (response time) increases or the connection is disconnected.

SUMMARY OF THE INVENTION The present invention has been made in view of the above background, and an object of the present invention is to eliminate or greatly reduce the need for creating a control program for controlling a measuring instrument, and to reduce the network. It is also an object of the present invention to provide an automatic measurement system that is less affected by delay time fluctuation due to network congestion and disconnection when a system is constructed using the system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of the automatic measurement system according to the embodiment. As shown in FIG. 1, in this automatic measurement system, two measuring instruments 1 and 2 and one controller 3 are connected by a communication line 101, and one user machine 4 and one controller 3
Are connected by a communication line 102.

The measuring instrument 1 includes a storage device 10, control program modules 11A and 11B stored in the storage device 10, a measurement function unit 12, and a control unit 13.
The storage device 10 uses a storage element such as a ROM, but may be configured by a RAM (random access memory) or the like as described later. The measurement function unit 12 is responsible for an actual measurement operation in the measuring device 1, and the control unit 13 controls each unit in the measuring device 1 based on a command from the controller 3.

Here, the control program module 11A
Is a program library including control program modules for controlling various detailed operations in the measurement function unit 12. These control program modules are formed by a combination of control commands for the measurement function unit 12. On the other hand, the control program module 11B
Is a program including a control program module for controlling various detailed operations of the control program module 11A. More specifically, the control program module 11B is a program that governs the overall operation of the automatic measurement system, such as instructing the start and end of measurement and reporting the status of measurement execution. As described above, the present embodiment has a structure in which the measuring instrument is controlled stepwise by the two control program modules 11A and 11B.

The measuring device 2 has the same configuration as the measuring device 1 and includes a storage device 20, control program modules 21A and 21B stored in the storage device 20, a measurement function unit 22, and a control unit 23. These correspond to the storage device 10, control program modules 11A and 11B, the measurement function unit 12, and the control unit 13 provided in the measuring instrument 1, respectively.

The controller 3 controls the measuring instrument 1 and the measuring instrument 2 to perform automatic measurement, and comprises an interface 31 and a control program main body 32 stored in a storage device (not shown). Interface 31
Performs transmission and reception between the controller 3 and the communication line 101 or 102. The control program main body 32 is a program for executing the control program modules 11A and 21A read from the measuring instruments 1 and 2, respectively, and roughly measures the measuring instrument 1, the measuring instrument 2, the user machine 4, the communication line 101, and the communication line 102. Control (ie, measuring device 1 and measuring device 2)
Control of the overall operation of the system, such as start and end of measurement
I do. That is, the measuring instrument 1 is included in the control program main body 32.
And the detailed control of the operation of the measuring instrument 2 is not described,
The detailed control is performed by the control program modules 11A and 21A incorporated in the control program main body 32.

The user machine 4 is a device for controlling the entire operation of the automatic measuring system, and is configured to control the measuring instruments 1 and 2 via the controller 3. The user machine 4 includes an interface 41 and a control program main body 42 stored in a storage device (not shown).
Consists of The interface 41 performs transmission and reception between the user machine 4 and the communication line 102. The control program main body 42 includes a control program module 11B read from the measuring instruments 1 and 2 via the controller 3,
21B, which is a program for executing a general control of the measuring device 1, the measuring device 2, the controller 3, the communication line 101, and the communication line 102 (that is, a system for starting and ending the measurement of the measuring device 1 and the measuring device 2). Control of the overall operation of. That is, the control program main body 42 also includes the measuring device 1 and the measuring device 2.
The detailed control of the operation is not performed by the control program modules 11B and 21B incorporated in the control program body 42.

As can be understood from the above description, the communication line 101 is mainly used for communication necessary for controlling the measuring instrument 1 and the measuring instrument 2, and the communication line 102 is used to instruct the start and end of the measurement and the measurement. Information and the like for the implementation status report are transmitted and received. That is, the amount of communication data transmitted and received on the communication line 101 is large, and the processing speed of the communication line 101 greatly affects the measurement processing speed. For this reason, it is necessary to use a communication line 101 that does not have a large delay time and has no danger of disconnection.

On the other hand, the amount of communication data transmitted and received on the communication line 102 is small, and the processing speed of the communication line 102 does not significantly affect the measurement processing speed. Therefore, the communication line 102
Can be used in a network where the delay time is large and there is a risk of disconnection.
And the Internet are candidates. And communication line 1
If the Internet or the like can be used as 02, the distance between the controller 3 and the user machine 4 is virtually unlimited.

Next, the operation of the automatic measurement system having the above configuration will be described. First, the operator sets the user machine 4
The user machine 4 instructs the start of measurement by operating a control panel (not shown).
The operation starts according to. That is, the control program main body 42 on the user machine 4 commands the control program main body 32 in the controller 3 to read out the control program module from each measuring instrument via the interface 41 and the communication line 102. Then, the control program main body 32 executes the interface 3 according to the received command.
1 and the communication line 101, the read command of the control program modules 11A and 11B is transmitted to the measuring instrument 1 and the control program module 21A is transmitted to the measuring instrument 2.
, And a read command of 21B.

When receiving the read command from the controller 3, the control unit 13 in the measuring instrument 1 interprets the command and reads the control program module 11 from the storage device 10.
A and 11B are read, and these control program modules are transmitted to the controller 3 via the communication line 101. When receiving the control program modules 11A and 11B from the measuring instrument 1, the controller 3 incorporates the control program module 11A into the control program main body 32 and transmits the control program module 11B to the user machine 4. Similarly, the control unit 23 in the measuring instrument 2
Receives and interprets the read command from the controller 3, and transmits the control program modules 21A and 21B read from the storage device 20 to the controller 3 via the communication line 101. As a result, the controller 3 incorporates the control program module 21A received from the measuring instrument 2 into the control program main body 32 and transmits the control program module 21B also received to the user machine 4.

The user machine 4 receives the control program modules 11B and 21B from the controller 3 via the communication line 102, and incorporates these control program modules into the control program body 42. When the installation process is completed, the user machine 4 starts the measurement operation. That is, the user machine 4 controls the control program modules 11A and 21A on the controller 3 according to the control program modules 11B and 21B incorporated in the control program body 42. Thereby, the control program modules 11A and 21A instruct the control unit 13 in the measuring device 1 and the control unit 23 in the measuring device 2 to perform the actual measuring operation using the measuring function unit 12 and the measuring function unit 22. Let

In this way, the detailed measuring operations of the measuring device 1 and the measuring device 2 are controlled based on the control program modules 11A and 21A taken into the controller 3. Thereafter, when the operator instructs the user machine 4 to report the measurement execution status or terminate the measurement, the control program main body 42 on the user machine 4
This is notified to the control program body 32 above. Thereby, the controller 3 collects information on the measurement execution status from the measuring devices 1 and 2 or the measuring devices 1 and 2
To the end of measurement. When the report of the measurement execution status is instructed, the control program main body 32 on the controller 3 sends the collected information to the control program main body 42 of the user machine 4, and the information sent on the user machine 4 side. Necessary processing such as display and printing of is performed as appropriate.

As described above, according to the present embodiment, only a read command of the control program module is newly standardized as a command sent from the controller 3 to the measuring instruments 1 and 2. As a result, the measuring instrument 1 and the measuring instrument 2 having unique commands necessary for the operation can be controlled by the controller 3 with the optimal commands. This read command can also be used when reading the control program modules 11B and 21B from the measuring instruments 1 and 2 to the user machine 4 via the controller 3. As described above, according to the present embodiment, the commands to be provided for each measuring instrument are different depending on the use or function of the measuring instrument. Control commands can be executed without standardizing commands between measuring instruments.

Further, according to the present embodiment, the control program main body 42 on the user machine 4 has only a read command of the control program modules 11B and 21B and a function of incorporating and executing them in the control program main body 42. Just do it. Therefore, the scale of the control program main body 42 is reduced, and the storage capacity of the storage device for storing the control program is also reduced. Similarly, the control program body 32 on the controller 3 also reads the control program modules 11A, 11B, 21A and 21B, transfers the control program modules 11B and 21B to the user machine 4, and executes the control program modules 11A and 21B.
It is only necessary to have the function of incorporating and executing A.
Therefore, the size of the control program main body 32 can be reduced, and the storage capacity of the storage device required to store the control program main body 32 can also be reduced.

Further, in this embodiment, the controller 3
It is not necessary to install in the controller 3 control program modules corresponding to all measuring instruments that may be connected to the controller 3 in advance. In other words, the measuring instruments connected at the start of measurement (in this case, measuring instrument 1 and measuring instrument 2)
It is sufficient to read out only the control program module corresponding to the above from each measuring instrument and combine it with the control program main body 32, and the storage capacity required for the controller 3 can be suppressed.

[Applications / Modifications] (1) TCP / IP (Transmissi
A communication line operated by a protocol such as on Control Protocol / Internet Protocol) may be used. A typical example of such a communication line is 10BASE-2 / 10BA.
There are standards such as SE-5 / 10 BASE-T. When these communication lines are used, when a large number of users use the communication lines, problems such as an increase in delay time and a risk of disconnection occur. However, in the present embodiment, since the main communication for automatic measurement is performed via the communication line 101, such a problem hardly affects the measurement itself.

(2) HTTP is used for measuring device 1 and measuring device 2.
(HyperText Transfer Protocol) server function and FTP
(File Transfer Protocol) A server function may be provided, and when reading out the control program modules 11A, 11B, 21A, and 21B from these measuring instruments to the controller 3, the server function of the measuring instrument may be used. As a result, the transfer commands of these control program modules are performed inside the HTTP protocol processing or the FTP protocol processing, and can be clearly distinguished from the control commands for instrument control that are processed after these protocol processing.
Therefore, it is possible to avoid the danger that the control command sent to the measuring instrument and the read command of the control program module are duplicated and cause confusion. (3) The controller 3 is provided with an HTTP server function, an FTP server function, or a proxy server (proxy server) function. When the control program modules 11B and 21B are read from the controller 3 to the user machine 4, the server function of the controller 3 is used. You may use it.

(4) The control program module 11A,
11B, 21A, and 21B may be described in a source program or an intermediate code of a predetermined program language (for example, the above-described BASIC language), and the controller 3 and the user machine 4 may have an execution environment for the source program or the intermediate code. . That is, the controller 3 and the user machine 4 are provided with a compiler of a source program and an interpreter of an intermediate code, and the controller 3 and the user machine 4 use a machine used by a CPU (central processing unit) that controls the controller 3 and the user machine 4. Translate it into words and execute it.

By doing so, since each control program module does not depend on the type of CPU, the control program modules can be unified. In addition, the creation of the control program module in a programming language facilitates its creation. If these control program modules are described in the programming language JAVA (registered trademark) and the controller 3 and the user machine 4 are provided with a JAVA language execution environment, affinity with a network environment such as the Internet is enhanced. .

(5) A rewritable IC (integrated circuit) memory such as a RAM or a rewritable storage device such as a hard disk or a magneto-optical disk is used as the storage device 10 and the storage device 20 to rewrite data from outside the system. The measuring device 1 and the measuring device 2 may have a function of rewriting the contents of the storage device 10 and the storage device 20 according to the command. In this case, the control program modules 11A, 11B,
Since the control program modules 21A and 21B are rewritable, these control program modules can be appropriately revised to prevent their obsolescence. In addition, a known security function for the storage device 10 or the storage device 20 may be provided in the control unit 13 or the control unit 23 so that writing to these storage devices may be prohibited. As a result, the control program modules 11A, 11B, 21A, 21B due to malice or accidents
Can be prevented from being rewritten, and security is ensured.

(6) All functions of the controller 3 and the communication line 101 may be incorporated in the measuring instruments 1 and 2. That is, the interface 31 and the control program main body 32 constituting the controller 3 are provided inside the measuring instrument 1 and the measuring instrument 2, respectively, and the interface 31 and the control units 13 and 23 are connected by a bus corresponding to the communication line 101.
The measuring instruments 1 and 2 are connected to the communication line 102 via the interface 31. The process of incorporating the control program modules 11A and 21A into the control program main body 32 is performed inside the measuring instruments 1 and 2.

(7) In the above-described embodiment, the control program modules 11A, 11A read from each measuring instrument
B, 21A, and 21B are incorporated into the control program main body 32 or the control program main body 42 and executed. However, these control program modules may function as a single control program independent of the control program body.

(8) Controller 3 and user machine 4
On the other hand, a distributed inter-object communication mechanism, which is an existing technology, may be applied. By doing so, the measuring instruments 1 and 2 and the control program modules 11A, 11B, 2
The controller 3 and the user machine 4 are physically separated from each other as described above without any change to 1A and 21B, and the controller 3 and the user machine 4 are handled as if they were integrated into one controller. It becomes possible.

[0039]

As described above, according to the first aspect of the present invention, the communication line connecting the user machine to the controller and the communication line connecting the measuring instrument to the controller are made independent, and the detailed operation of the measuring instrument is performed. Is stored in a measuring instrument, and the first and second control programs are read out to a controller and a user machine, respectively. The first control program is controlled according to the second control program, and the detailed operation of the measuring instrument is controlled according to the first control program.

As described above, since the control program itself for controlling the detailed operation of the measuring instrument is built in the measuring instrument, the creation of the control program becomes unnecessary or the work is greatly reduced. The automatic measurement system can be easily used. Further, since it is not necessary to store a control program that is not required at the present time in the controller or the user machine, the capacity of the storage area of the control program in the controller or the user machine can be suppressed, and an inexpensive system can be constructed. Further, since the control program is built in the measuring instrument side, there is no problem that a storage medium such as a CDROM in which the control program is stored is lost.

According to the second aspect of the present invention, the controller is built in the measuring instrument and the second communication line is omitted. The overall configuration becomes simpler, and a cheaper system can be constructed.
According to the third aspect of the present invention, since the user machine and the controller or the measuring instrument are connected by a network, the measuring instrument can be controlled from a remote place using the Internet or the like.

According to the fifth aspect of the present invention, since the measuring instrument reads the first or second control program using its own server function, the transfer of these control protocols is performed by the protocol processing used by the server function. Since it is performed internally, there is no danger that the control command sent to the measuring instrument and the reading of these control programs will be duplicated and cause confusion. According to the seventh aspect of the present invention, the first or second control program is described in the form of a source program or an intermediate code, and the first or second control program is executed on the controller side or the user machine side which executes the first or second control program. Since the program is translated, there is no need to prepare a control program for each type of controller or user machine.

According to the eighth aspect of the present invention, the JA
Since the first or second control program described in the VA language can be executed by the controller or the user machine,
Affinity with network environments such as the Internet increases. According to the ninth aspect of the present invention, since the first or second control program can be rewritten, the control program can be appropriately revised to prevent its obsolescence.

According to the tenth aspect of the present invention, the rewriting of the first or second control program can be prohibited, so that the rewriting of the control program due to malicious or accident is prevented and the security is ensured. be able to.
Further, even when a network such as the Internet is used as the first communication line, damage due to a computer virus or the like can be prevented.
