Description

Telecommunications interface and related methods for collecting and sending data

field of invention

The present invention generally relates to remote monitoring of usage information, and specifically relates to a device and related method for sending, receiving, storing, processing and forwarding digital information directly to remote receiving equipment by various means. The device includes: using Global Standard for Mobile Communications (GSM), Time Division Multiple Access (TDMA) technology, Code Division Multiple Access (CDMA) technology, Frequency Division Multiple Access (FDMA) technology, Personal Access Communications System (PACS) or other Personal Communications System (PCS) is a digital technology standard communication system for voice and data communications.

Background of the invention

Currently, many utility meters are monitored by an employee visually inspecting each meter and then recording usage data. In order to reduce the manpower required to collect utility usage data, several methods and devices for automatically collecting utility usage data have been proposed.

An apparatus for monitoring utility rate data is disclosed in US Patent No. 4,803,632 to Frew et al. The device is powered separately and is capable of short-range infrared transmission of utility bill data. There is also a hand-held manipulator (wand) capable of receiving transmitted data. A meter reader uses the hand-held operator by bringing it close to the monitoring equipment to receive electrical data to be stored in a removable instrument carried by the employee. The employee then takes the saved electrical data back to the utility company where it is downloaded from the portable instrument and used to calculate the customer's utility bill.

U.S. Patent Nos. 5,010,568 and 5,161,182 to Merrian et al. disclose a utility rate monitor that is connected to a subscriber's telephone line via a modem. The monitor calculates and saves the user's utility rate data. The utility company periodically calls the monitor, and after establishing a modem connection between the utility company and the monitor, the monitor sends utility bill data to the utility company and uses the data to calculate the customer's utility bill one.

A device for monitoring utility rate data is disclosed in US Patent No. 4,940,976 to Gastouniotis et al. The user's utility bill data is collected by instruments located in the user's premises. The monitoring device transmits the utility bill data via radio frequency to an intermediate storage station capable of storing utility bill data for up to 10,000 dwellings. Periodically, the staging station sends the stored data to the utility company via radio frequency link, cable television line, or telephone line. The utility data is then used to calculate the user's bill.

What is needed is a system capable of monitoring utility rate data and other information for changes in meter reading schedules and data queries (retrieval) with varying degrees of frequency and capable of wirelessly transmitting digital data to desired remote devices.

Therefore, it is desirable to provide a data collection device that receives data from utility meters and other devices.

In addition, there is a need to provide a method of transmitting digital information to a remote receiving device, which in one embodiment can be transmitted via GSM, PACS, FDMA, CDMA, or TDMA digital technology operating at a certain frequency.

Data collection equipment is also required to provide an interface to a telecommunications line at a location to provide a connection to a digital personal communication system or equivalent wireless network.

In addition, it would be desirable to provide a device capable of receiving requests for data and capable of sending data using the short message service of the Personal Communications System protocol.

There is also a need to provide an apparatus that creates an interface between a wired telecommunication equipment/system and a wireless digital PCS telecommunication network in which said apparatus operates at a defined frequency bandwidth.

In accordance with the present invention, there is provided an apparatus for automatically collecting collected data and digitally transmitting that data to a remote device, which in one embodiment can be transmitted using GSM, PACS, FDMA, CDMA or TDMA digital techniques. These transport protocols represent mobile telecommunication systems capable of digital voice and data transmission operating within specific radio frequency bandwidths. The apparatus includes means for detecting and collecting data at a first location. If the detected data is analog, the analog data is converted into digital data. The collected data may be sent to the data collection device for storage and/or processing before the data is digitally transmitted to the desired remote device. Within the data collection facility there is a processing and storage unit which is also used to convert and encode the data into the desired format and to store the data in electronic form. The processing and storage means may include a central processing unit (CPU) for processing the collected data, an erasable programmable memory (EPROM) for storing programs for processing the collected data, and a RAM for storing the data before sending the data. access memory (RAM).

Periodically, or when required by the interested party, the apparatus transmits digital data on any radio frequency band to remote receiving equipment via a telecommunications transceiver unit and network utilizing GSM, PACS, FDMA, CDMA or TDMA digital technology. The GSM, PACS, FDMA, CDMA or TDMA network can transmit the stored and/or processed data on a digital GSM, PACS, FDMA, CDMA or TDMA control channel or short message system, delivering the data to a remote receiving device. In one embodiment, the device is capable of transmitting the data over a personal communication system network using a frequency of approximately 1900 MHz.

Although the present invention has been described in relation to a personal communication system network using GSM, PACS, FDMA, TDMA or CDMA technology, it should be understood that a personal communication system may include any other wireless system that uses digital transmission techniques to transmit information to a remote receiving device.

In another embodiment, the means for automatically collecting data may be connected to a telecommunications system or equipment (e.g., an existing hard-wired telephone system) through a connection device to establish communication with a wireless telecommunications network (e.g., GSM, PACS, FDMA, TDMA, or Code Division Multiple Access (CDMA) networks). Such a connection then allows voice or data to be sent over a wireless telecommunications network at a location using existing telecommunications systems or equipment.

Additionally, the collected meter utility data can be stored electronically within the optical meter reading device. The collected data can then be sent to another location via a wired or wireless connection. Wireless transmissions of collected data may be sent on frequency bands not commercially licensed. Transmitted data can be received by the data collection device and then digitally transmitted.

According to another aspect of the invention, the data collection device transmits and receives data using the short message service portion of digital voice and data communication digital technologies such as GSM, PACS, FDMA, TDMA or CDMA. The short message service portion of these digital transmission protocols is the means by which mobile subscribers (MSs) send and receive a protocol-specific number of data characters, ie devices capable of sending over personal communication systems. A method for sending data sequences via a personal communication system short message service transport protocol is disclosed. In the method, at first, the short message service part of the personal communication system transmission protocol is used to send a data request from the remote device to the data collection device; the request is received at the data collection unit and the request is interpreted; according to the interpretation of the request, the data The collection device compiles (compiles) the data requested by the remote device; then, sends the compiled data to the remote device through the control channel of the short message service part of the personal communication system transmission protocol.

The time stamping device provides circuitry capable of providing data versus time that can be stored in the electrical memory of the data collection device for compilation and output upon request by a remote device. Timestamping enables data to have a relationship to a time period when it was collected. This temporal relationship is useful in making a later reported usage fee list or consumption data list that reflects the time period when the items are consumed, the consumption is detected and the consumption data is collected, saved and stored in the data collection facility. Various parameters can be included but are not limited to collection frequency, relative time stamps, and consumption notifications, among others. Each of these specific parameters may be changed or modified upon request in accordance with requests and instructions received from the remote device.

The step of sending the data request includes accessing the short message service portion of the control channel of the personal communication system transport protocol. The remote device sends the data sequence to the data collection device via the short message service portion of the personal communication system transmission protocol. The data collection unit receives short message service data and interprets data requests. After compiling the data according to the request, the data collection unit accesses the short message service part of the transmission protocol of the personal communication system. The compiled data is formatted into a short message containing the data previously requested from the remote device. The data collection device sends the data sequence to the remote device via the short message service portion of the personal communication system transmission protocol.

Detailed Description of the Invention

According to one aspect of the present invention, an automatic meter reading device for collecting and transmitting utility rate data and other information is provided. Such data collection equipment collects data from utility meters and other equipment and can send this data to the data collection equipment through a wired or wireless connection. Within the data collection device is a wireless transmitter/receiver capable of transmitting digital data. Because wireless communication technology allows each individual data collection device and its internal data registers to have a unique address, the remote device is able to query individual data collection devices and specific data registers of individual data collection devices.

According to another aspect of the present invention, a meter reading device with improved depth of focus is provided. The improved meter reader includes an electromagnetic radiation (eg, optical or infrared) transmitter and receiver. Furthermore, a device is provided for reflecting an electromagnetic beam for optical coupling between the transmitter, receiver and a rotatable disc, dial or mechanical type indicator provided in the utility meter. The improved meter reader can be integrated into existing meters without having to replace various existing utility meters.

In the block diagram of FIG. 2 , the data collection device includes a data collection receiver 110 connected to a meter or other device 100 . The data collection receiver 110 includes a direct-wired input receiver 116 for those meters or other devices 100 that are one-wire connected to the receiver 110 and also includes a direct-wired input receiver 116 for those meters or other devices that are connected wirelessly to the receiver 110 100 of super regenerative or spread spectrum receiver (superregenerative or spread spectrum receiver) 114 . Connected to the data collection receiver 110 is a data collection device 120 which is capable of calculating and saving usage consumption or status data of existing meter readers or other devices. Also, connecting the GSM, PACS, FDMA, CDMA or TDMA telecommunication unit 130 to the data collection device 120 enables data received (from the meter 100) to be digitized via the GSM, PACS, FDMA, CDMA or TDMA digital technology network short message service. to a remote device or location 140.

In one embodiment, the data collection device can be miniaturized to be hidden behind an electronic meter. This embodiment includes a transceiver capable of transmitting and receiving information over a digital GSM, PACS, FDMA, CDMA or TDMA network. Additionally, this embodiment includes a receiver for collecting data from a wireless meter reader or other data source associated with the data collection device.

Referring to FIG. 3 , the GSM, PACS, FDMA, CDMA or TDMA telecommunications unit 130 includes a GSM, PACS, FDMA, CDMA or TDMA transmitter/receiver 134 that receives data from the data collection device 120 . The GSM, PACS, FDMA, CDMA or TDMA transmitter/receiver can then digitally transmit data to and from the remote receiving device 140 via the GSM, PACS, FDMA, CDMA or TDMA network control channel or short message service 136 . Most personal communication systems in North America contain spectrum allocations between 1850 and 1990 MHz (here, 1900 MHz bandwidth). In a preferred North American embodiment, the GSM, PACS, FDMA, CDMA or TDMA transmitter operates in the 1850 to 1990 MHz frequency range. It should also be understood that the data collection device of the present invention may be used in conjunction with any wireless network employing digital control channels or short message service information transmission technologies. In addition to existing wireless network technologies such as personal communication systems, namely GSM, TDMA, CDMA, frequency division multiple access (FDMA) and personal access communication systems (PACS), it should be understood that the present invention can be used with digital Used in conjunction with other wireless network technologies to transmit information using Control Channel or Short Message Service type technologies.

Referring to Figure 1, data from all meters 100 is transmitted to a data collection facility 101 via, for example, a wired or radio frequency connection. The data collection facility 101 is also capable of receiving data from meters manufactured by various companies that are stocked/used for various methods of collecting, storing and then releasing data. Data from the data collection facility 101 is transmitted via the network infrastructure to a base transceiver system (BTS) 102 using a digital control channel or short message service. This data is transmitted from BTS 102 to Base Station Controller (BSC) 106. The data is then transmitted from the BSC 106 to the Mobile Switching Center (MSC) 103. The Control Channel Packet Assembler/Disassembler or Short Message Service Center 105 is physically located in the MSC 103. At this location, the data stream is transmitted in a common data format (eg Integrated Services Digital Network (ISDN), Short Message Service Standard Service Foundation (SMS), etc.). Data is transmitted in a technology-dependent control channel structure in the form of consecutive transmission units. Each transmission unit comprises a certain number of transmission packets (for example, in a GSM personal communication system radio network, each transmission unit has five transmission packets). Due to the typical use of control channels such as GSM, many transmission packets do not contain wireless network transmission information and such packets are considered "dummy" packets.

The embodiment of Fig. 1 shows that the GSM control channel packet assembler/disassembler Short Message Service Center (SMSC) 105 continuously monitors the GSM data stream and can separate therefrom the control channel transport packets required for system control, or from other Other system information is separated from other channel transport packets of the specificity. For this reason, it should also be understood that although the control channel assembler/disassembler 105 is physically located in the MSC 103, it could also be logically located at any point between the BTS 102 and the MSC 103. Each data packet has a "header" which includes a specific sequence of numbers identifying a packet as a "dummy" packet, a GSM control packet or a specific data packet. The transmission and reception of specific transport packets by the data collection device 101 is detected by the control channel packet assembler/disassembler 105, "stripped", interrogated, quantized, and simultaneously replaced by a "dummy" packet, which is then transmitted to the MSC 103. The "stripped" packets containing information from data collection device 101 may be transmitted to remote receiving device 140 for processing. Conversely, instructional information for data collection device 101 can be transmitted from remote receiving device 140 to control channel packet assembler/disassembler 105 and processed by stripping dummy packets in the data stream and inserting control data with instructional information packet and introduced into the control channel. The instruction information is transmitted back to the data collection device 101 via the MSC 103, the BSC 106 and the BTS 102. Thus, the control channel packet assembler/disassembler 105 alternately operates on a tandem on incoming and outgoing control channels between the BSC 106 and the MSC 103. In one embodiment, the control channel packet assembler/disassembler 105 may be a computer programmed to perform the functions described above.

More specifically, in structures using GSM technology, the invention removes "dummy" packets that do not contain information and replaces these "dummy" packets with diverted transport packets. The diverted transmission packets may contain data and instructions that the remote device uses to control the various data collection devices. In addition, the diverted transmission packets may also contain data sent by the data collection device to the remote device. Diverted transport packets can be diverted between BTC 102 and MSC 103. The diverted transport packets are replaced by "null" transport packets, which makes the operation of the system transparent to the MSC 103. Operating in this manner, remote receiving device 140 and data collection device 101 create a two-way communication link.

In GSM (eg PACS, FDMA, CDMA or TDMA technologies) there are logical channels and radio frequency channels for communication. Additional channels or parts of logical channels are used as control channels. (GSM) control channels or their equivalents in other digital technologies including PACS, FDMA, CDMA or TDMA networks are normally used to verify caller identity and billing information. In addition, the control channel is typically used to switch between communication towers for the caller when the caller is about to move beyond the coverage of the transmitting tower. Thus, control channels or their technical equivalents are sometimes not used in digital GSM, PACS, FDMA, CDMA or TDMA communication networks. During such non-use times, the data collection device 101 is able to transmit data via the network system without interfering with the transmission of other types of control channels. As mentioned above, in the present invention control channels of the GSM, PACS, FDMA, CDMA and TDMA types are always fully occupied by a stream of transport packets, but most of the transport packets consist of "dummy" transport packets. "Dummy" packets can be "stripped" from the data stream on the way to BTS 102. The "stripped" packets are replaced with dummy transport packets containing addresses and instructions for the data collection device 101 . Address information contains the unique address of each individual data collection device. Thus, the present invention is capable of communicating with individual data collection devices because information can be sent to the unique address of the desired data collection device. Diverted transport packets received via GSM, PACS, FDMA, CDMA or TDMA BTS 102 are stripped and not sent to MSC 103. This packet "stripping" allows the system to be installed without software modifications to the Home Location Register (HLR), Vehicle Visitor Location Register (VLR) or MSC 103. In this way, data collection device 101 is capable of sending or receiving data at any fixed or desired time. Thus, data can be sent and received at a time when other control channel transmissions are minimal. The data transmitted on the control channel or technical equivalent is digital, therefore, the digital data from the data collection device 120 can be transmitted on the GSM, PACS, FDMA, CDMA or TDMA network, thereby eliminating the need for digital to analog conversion. need.

Existing meter query systems are not intelligent and cannot query individual or specific devices. Some interrogation systems send a report command through the network transmission system to all meters on a certain part of the network. The meters in these partitions then send the data in (time) order. The meter receives this command and then reports the data multiple times over the wireless network, regardless of whether other meter readings are occurring at the same time. This principle of operation assumes that the data transmissions from the individual meters do not interfere with each other through an interleaved polling and transmission scheme, and that readings from one (if not more) of the many meter reading operations arrive at the data collection in an uncorrupted manner point.

In the present invention, the data collection device transmits data when requested by a GSM, PACS, FDMA, CDMA or TDMA signal. Thus, specific data registers of a single meter can be read without having to enable all meters in an area for this. The operation of the interrogation meter reduces the traffic of the GSM, PACS, FDMA, CDMA or TDMA communication system and optimizes the efficiency of the system operation.

Referring to FIG. 4 , the meter or other device 100 may be remote from the data collection device 120 (see FIGS. 3 and 5 ) and connected via a wireless data collection unit 148 . Data may be collected from meters or other devices by universal meter reading sensors 156 . The data is conditioned and preferably encrypted using signal conditioning circuitry 154 prior to transmission. Periodically, transmitter controller 152 directs transmitter 150 to transmit data to super-regenerative or spread spectrum receiver 114 as shown in FIG. 2 . Transmitter 150 is capable of operating with frequency modulation (FM) or amplitude modulation (AM) on unlicensed radio frequencies such as 27, 49, 300 or 902-928 MHz. Preferably, the transmitter 150 will operate using amplitude modulation over the frequency range of 902-928 MHz.

Data transmission from transmitter 150 to data collection device 120 (shown in FIG. 2 ) may be accomplished using inductive (L) and capacitive (C) super-regenerative circuits as described in detail below. LC circuits are a relatively inexpensive option for short-distance wireless transmission of data. After the data is transmitted to LC receiver 114 (shown in FIG. 2 ), as described above, the data may be transmitted to a remote device and location using GSM, PACS, FDMA, CDMA, or TDMA telecommunications unit 130, as shown in FIG. Show.

As shown in FIG. 4 , wireless data collection unit 148 can be remotely powered by battery 158 , which can be charged by solar cell 162 . The charging control unit 160 regulates the power from the solar cell 162, causing the battery 158 and supercapacitor 164 to be charged. In the event of a power loss, ultracapacitor 164 can be used as a backup power source. In another embodiment, the wireless data collection unit is powered by a long life battery pack.

Referring to FIG. 5 , the data collection device 120 further includes a data collection unit 210 . In one embodiment, data collection unit 210 includes a central processing unit (CPU) having electronic memory, such as erasable programmable read-only memory (EPROM), and a real-time clock. These devices are used to save, time and process the most recent meter output or other data. The data processing program/algorithm used by the CPU to process utility data is stored in EPROM via program data line 230 and cannot be changed after initial programming of the CPU for security reasons. In cases where data, algorithms, or any physical components of the data collection device 120 itself are altered, the data collection device 120 is capable of detecting erroneous data or algorithmic or physical intrusions, and is capable of sending A security breach signal.

A CPU has multiple data input and input (I/O) lines. Therefore, I/O lines not used by data devices can be used for additional applications. For example, additional wiring can be connected to a home security device with multiple sensors throughout the home. When a sensor detects an intrusion, the data collection device 120 can send a signal of the breach to a remote device located, for example, at a police station. Other home devices include home health monitoring devices that can detect a patient's health status and send that data to a hospital.

In another embodiment, the data collection device may use additional I/O lines to monitor usage status of vending machines and the like. For example, each vending machine located in a building can send its usage data to a common meter reading data collection device, which in turn sends the usage data to the vending company. Therefore, the vending company is able to replenish the vending machines, saving the manpower required to manually check each machine. The invention also covers applications including monitoring and control for irrigation sprinkler systems, oil well monitoring and control, water supply and drainage monitoring and control for industrial sites, flue discharge monitoring, real-time monitoring of urban air quality, remote weather Monitoring and monitoring of power failure locations.

Utility data is obtained from meter 220 and additional data lines 232 are used to monitor other equipment. Meter 220 may be wired or wirelessly connected to data collection device 210 . If the meter 220 is wirelessly connected, the data is preferably transmitted on an unlicensed frequency band, preferably 27, 49, 300 or 902-928 MHz.

The data collection device of the present invention is capable of reading multiple status and usage inputs as compared to other devices that read each device as a single element. Data collection devices condition data through CPUs to more efficiently use technology and spectrum. Additionally, the data collection device is capable of interfacing with many devices using wired or wireless media and inputs.

If wireless collection is used between the data collection equipment and the meters being read at a given location, the receivers and transmitters are very low cost and low specification, and they are similar to keyless entry systems. The safety and reliability of this low-cost system is achieved by CPU error checking in the data collection device. Data from wireless meters is periodically transmitted multiple times on multiple closely spaced unlicensed radio frequencies. A CPU in the data collection device controls a low-cost LC super-regenerative receiver to quickly search these frequencies for a valid signal to lock on to. In another embodiment, the device uses surface acoustic wave filter based transmitters and receivers. When this signal is received and latched, the CPU checks for errors before receiving and saving data (in this case meter reading data) for storage and later sending to the data collection site via a GSM, PACS, FDMA, CDMA or TDMA system data and the serial number of the wireless meter reader.

Also, the data collection equipment/utility meter reader system is low cost because it uses a variant of the existing meter infrastructure and simply adds an optical/infrared reader, which is less expensive than if equipped with a reading circuit It is much cheaper to replace the installed meter with a new one. Also, multiple meters and alarms are read or monitored at one location by one data collection device. As previously stated, by utilizing GSM, PACS, FDMA, CDMA or TDMA to control the packet data or short message service collection system, no software modification is necessary for any GSM, PACS, FDMA, CDMA or TDMA transmitting or receiving equipment.

As mentioned above, data transmission from meter 220 to data collection unit 210 can be accomplished using an LC super regenerative circuit to establish a wireless connection between unit 210 and meter 220 . In addition, if the meter 220 is connected wirelessly, the signal conditioning circuit 234 is used to filter out electromagnetic noise in the transmitted signal. When the meter is wired to the collection unit 210 , the signal conditioning circuit 234 may also be utilized to filter out noise and deliver a clean logic signal to the data collection unit 210 .

As shown in FIG. 5 , an opto-triac switch 250 is used to control the coil of a load shedding relay contactor 260 . Triacs are commercial devices used to isolate sensitive electronics from transient electrophoresis caused by switching high power loads. Controlling one or more of the load shedding relays 260 may allow the utility company to cut off power to low priority areas during times of power shortage or peak usage. For example, a user may enter into an agreement with the utility company to cut off power to his residence during a "brownout" period so that additional power can be supplied to a nearby hospital. The load shedding relay 260 can be activated by the utility company over the network to which the data collection equipment is connected, since the GSM, PACS, FDMA, CDMA or TDMA communication link is capable of two-way communication. Additionally, power wheeling devices may be attached to the data collection device 120 . The power conversion device may allow utility customers to compare utility rates from various utility companies in the area. If the user finds a more competitive utility rate, the user can utilize the power conversion device and data collection device 120 to switch to that utility company.

In one embodiment, the data collection device 120 is located in an extension of an existing electricity meter, but the data collection device 120 may be separately enclosed in a waterproof unit. In either case, the data collection device 120 can be powered by AC voltage obtained from the user's utility power line. The AC voltage is stepped down by power electronics 224, preferably producing a voltage signal of about 8V. A backup battery 226 is provided when AC power cannot power the data collection device 120 . Preferably, backup battery 226 is a gel battery or similar battery with a long life. Also, a safety switch 228 is provided to the data collection device 120 to detect if the power supply is tilted or its top cover is open. As shown in FIG. 3 , when the security switch 228 is activated, the data collection device 120 can report the security breach to the remote device 140 through the communication network.

When the data collection device 120 has finished processing, it sends the data over the network using GSM, PACS, FDMA, CDMA or TDMA communication circuitry 234 connected to the data collection unit 210 and antenna 242 . GSM, PACS, FDMA, CDMA or TDMA communication circuitry 234 allows data transmission to data user equipment via short message service or technical equivalents of the control channels of the GSM, PACS, FDMA, CDMA or TDMA network. As previously mentioned, the communication connections on the network are bi-directional links that allow remote devices or location and data collection devices 120 to send and receive data. Accordingly, interested parties may communicate with data collection device 120 to access data or other characteristics (eg, load shedding and power usage).

Referring to FIG. 5, the data collection device can also be connected to a telecommunications system line (e.g., an existing telephone line in a residence) 248 at the user's location to create a connection to a wireless telecommunications network such as a GSM, PACS, FDMA, CDMA, or TDMA network. connect. Accordingly, as shown in FIG. 5 , a vocoder 244 and a ring/tone generator 246 located within the data collection device 120 are connected to an existing telephone line 248 . The function of the ring/tone generator 246 is to create a dial tone and ring function for existing telephone lines connected to the wireless telephone network. The function of the vocoder 244 is to convert speech into a digital signal that can be sent over the wireless network. A wireless telecommunications network connection replaces the need for wired telecommunications services because it establishes a wireless telecommunications interface through the data collection device 120 at its location. In addition to providing wireless telephone service over existing telephone lines, the data collection device is capable of performing all of the above functions simultaneously.

In order to provide wireless telecommunication services over existing home phone lines, the ring/tone generator is used as an interface to couple the existing home phone line telecommunication equipment/system at its location with the wireless digital PCS telecommunication network. In FIG. 9, one embodiment of telecommunications interface coupling 300 includes, for example, a wired telecommunications network 310 comprised of existing wired telecommunications circuits within a building. Wired telecommunications equipment/system 310 is interconnected with digital PCS wireless network 320 through ringer/tone generator 330 . The data collection device 360 may also be connected to the ring tone generator 330 so that the data collection device 360 can transmit, for example, utility rate data or other data through the digital PCS data collection device 360 . To couple the ring/tone generator 330 to the digital PCS network 320 data collection facility 360, the ring/tone generator 330 is interconnected with a PCS transmitter/receiver 340, which can employ at least one remote PCS transceiver Base station 350 communicates. As noted above, in digital PCS wireless network 320, remote PCS transceiver base stations 350 include base station transmitters, base station controllers, and mobile switching centers.

In another embodiment, the ring/tone generator 330 or system has means to perform several functions while providing the telecommunications interface coupling 300 . These components include: data conversion means, means for determining the number of digits of a telephone number dialed from the wired telecommunication network, means for generating a transmission signal to the PCS sender/receiver, and Before dialing the phone number check and identify the device that dialed the number.

Data transformation means includes any device used to transform data. These devices include, but are limited to, digital-to-analog and analog-to-digital converters and digital protocol converters. In the ring/tone generator, the data collected by the data collection device must be converted into digital format before being sent to the PCS transmitter/receiver and sent over the digital PCS wireless network. Likewise, incoming data or voice tones from a wired telecommunications network must also be converted to digital format before being sent over a digital PCS wireless network. Conversely, data or voice tones that must be input to the wired telecommunications network are converted to an analog format or to another data format, such as a data format compatible with the Short Message Service (SMS) protocol of a particular digital PCS wireless network.

Means for determining the number of digits of a telephone number dialed from a wired telecommunications network includes any device capable of determining the number of digits dialed from a telecommunications network. In an embodiment, these devices may include electronic memory capable of storing a list of reference numbers. Electronic memory may be updated or changed by, for example, adding new read-only memory devices, reprogramming existing erasable-writable memory devices, and the like. Reprogramming of the memory device can be accomplished by sending data to the memory device via the wired telephone network or the PCS wireless network.

The length of the reference number can be 1 to 11 digits, in the preferred embodiment the length of the reference number is 3 digits. Reference numbers held in memory include area codes and local dialing prefixes recognized by the system. Additionally, each stored reference number corresponds to a specific dialed digit. Thus, by analyzing the number of digits dialed in the range 1 to 11, the system can determine how many digits were ultimately dialed, and can instruct the system to take a specific action after the last digit has been dialed.

When dialing a number from a wired telecommunications system, a converter can be used to convert an analog dial or analog touch tone signal into digital data. As individual numbers are dialed, the electronic memory buffer sequentially stores the dialed numbers as digital data in digital form. In addition, as the number is entered, the logic circuit sequentially analyzes the dialed number and the number stored in the reference number table. When the number is analyzed and the dialed number is equal to at least one stored reference number, the relevant length of digit telephone number to dial is sent to the system. Based on the length of telephone number digits sent to be dialed, the circuit determines when a particular length of digits has been dialed by sequentially adding the dialed numbers to those dialed numbers already held in memory.

For example, if the number 280 represents a local exchange prefix recognizable by the system, the number is stored in a memory table as a reference number and is associated with the number 7 because local telephone numbers are 7 digits in length. In operation, when numbers 280 are sequentially dialed as the first three digits of the dial stream, these numbers are stored and compared sequentially with the stored reference table numbers. Once the logic circuit determines that the dialed 280 matches a stored reference table number, the length of the digit telephone number (7) is sent to the system. The logic circuit determines that 3 digits were dialed, which are 2, 8 and 0, while the system waits for the other 4 digits to be dialed. Once the last digit has been dialed, the system will be instructed to take appropriate action, which includes providing a "send" command to the PCS transceiver.

In another embodiment, the number 1443 may represent a long distance request (1) and an area code (443), and if recognized by the system, the number will be stored in memory as a reference number. This reference number 1443 will be associated with a telephone number of length 11, which includes 1+area code (3 digits)+prefix (3 digits)+subscriber number (4 digits). In operation, as the number is dialed, if 1443 is entered sequentially, the logic circuit will send the phone number with a length of 11 to the system. The logic circuit determines that 4 digits have been dialed, which are 1, 4, 4 and 3, and the system will wait for the other 7 digits to be dialed in. Once the last digits have been dialed, the system is instructed to take appropriate action.

Typically, once the last digits have been dialed, the system extracts the dialed numbers saved in digital form and sends these numbers and a transmit signal to the PCS transmitter/receiver. The saved dial and send signals are sent to the PCS sender by a device capable of sending these commands. These devices include, but are not limited to, the data collection devices described. Once the transmit signal and phone number are received by the PCS sender/receiver, this information is sent over the PCS wireless network and the call is completed.

The memory table has a certain storage space and is programmed to identify and send feature commands specific to a particular personal communication system for feature controls. These feature commands are the equivalent of those used on wired telephone communication systems, such as but not limited to ^* (asterisk) 72, ^* (asterisk) 73, and hookflash.

It should be noted that if the number dialed is not equal to or does not match the stored reference number, the system will take no action and no information will be sent over the PCS wireless network. Furthermore, the system only generates a transmit signal when the dialed number matches a reference number held in a memory table and a certain number of digits have been dialed (entered). In another embodiment, the system may have a time-out facility for sending the saved number to the PCS sender/receiver and generating a send when a specified amount of time has passed since the last digit was dialed. Signal. In a preferred embodiment, the system will wait 30 seconds between dialed digits. This timeout feature can be used as an alternative to digit analysis or when the number dialed does not match a stored reference number.

In another embodiment, the ringer/tone generator, or system, includes a ringer signal generator capable of generating a ringer signal to a house wired telephone system in response to an incoming call over the PCS wireless network. The ring signal generator includes equipment capable of generating a ring signal, including but not limited to a power supply capable of supplying a specific voltage to the wired telecommunications system when a call is received from the PCS wireless network. In one embodiment, the ringing signal may be generated by providing a voltage of 80 to 115 volts at a frequency of 20 Hz. Additionally, the ringer/tone generator may include means for determining an off-hook condition. Off-hook situations include, for example, situations when a user lifts the receiver of a wired telecommunications device/system. The wired telecommunications equipment/system produces a dial tone when the receiver is lifted. Thus, an off-hook condition may be a request by the wired telecommunications system to generate a dial tone. Means for determining an off-hook condition includes any device for determining whether a wireline telecommunications device/system has made a dial tone request.

In one embodiment of the present invention, as shown in FIG. 10, and as described above, data can be collected by a data collection device 400 that sends data to a data collection device 400, and the data is collected in the data collection device 400 , output as cleartext. In one embodiment, the plaintext is converted to a digital format and then sent as a short message by the PCS transmitter/receiver 430 over the PCS wireless network. Converted data can be transmitted by PCS transmitter/receiver 430 over the PCS wireless network using Base Transceiver Station (BTS) 400, Base Station Controller (BSC) 440 and Mobile Switching Center (MSC) 460, as described above. Finally, the data is received by a remote receiving device (not shown). The transmission scheme described above uses only the digital PCS wireless network to transmit data. In areas where PCS wireless network access is not available, the data collected by the data collection equipment can be sent using an out-of-band modem using an existing wired telecommunications network, such as the public or private switched telephone network (PSTN).

Additionally, as shown in FIG. 10, it should be understood that the data request 490 can be sent to the data collection device via the PSTN 480 as well as the PCS wireless network. The data request 490 is in clear text format, which allows the data to be sent over the PCS wireless network as a Short Message (SM). Plaintext data is sent to switching center (MSC) 460 via PSTN480, then to short message center 470, it converts plaintext data into short message (SM), and SM is routed to base station controller (BSC) 440, remote base transceiver station (BTS) 450 and PCS transmitter/receiver 430 . The SM is received in a clear text format recognizable by the data collection device 400 . Data collection device 400 is capable of responding to data request 490 .

In another embodiment shown in FIG. 10, a data collection device 400 collects data. Data is sent to the PCS wireless network as Short Messages (SM) in clear text format. Typically, the Short Message Service (SMS) of the PCS wireless network allows 140 to 160 characters per message to be sent. In one embodiment, the data collection device 400 divides the data into packets having a character length of 140 to 160 characters. As noted above, requests for data or other information may be sent to data collection facility 400 using PSTN 480.

Data from data collection device 400 is sent to out-of-band modem 420 , which is connected to PSTN 480 . Out-of-band modem 420 modulates the converted data over a specific frequency bandwidth and transmits the data to Mobile Switching Center (MSC) 460 via PSTN 480 . The converted data is recognized by MSC 460 as a short message (SM), and the converted data is sent to the Short Message Service 470 of the PCS wireless network. A short message (SM), including converted data, from SMS 470 is sent to a remote receiving device (not shown). Data or information request messages sent to data collection device 400 via PSTN 480 may also be sent to out-of-band modem 420 connected to PSTN 480 .

In one embodiment, as shown in FIG. 11 , out-of-band modem 420 uses modulator 510 to modulate data sent from data collection device 400 to PSTN 480 , and uses demodulator 500 to demodulate data sent from PSTN 480 to data collection device 400 . In one embodiment, the data is modulated over a bandwidth of 600 Hertz (Hz). In a preferred embodiment, data is modulated over a bandwidth of approximately 3200 to 3800 Hz. Typically, on the PSTN, the voice bandwidth theoretically ranges from about 30 to 4000 Hz, but in practice, the bandwidth used to transmit voice data is about 300 to 34000 Hz. Thus, the operating bandwidth of an out-of-band modem is approximately 3200 to 3800 Hz, which is considered out-of-band because the PSTN typically does not use this bandwidth when transmitting voice. The utilization of this bandwidth for sending data over the PSTN is then "transparent" to PSTN users.

In order to ensure that the data received and transmitted by the data collection device 400 is within this bandwidth, low pass filters 530 and 540 are employed. In the preferred embodiment, low pass filters 530 and 540 remove transmission data sent at frequencies below 3000 Hz. Additionally, in the embodiment shown in FIG. 11 , lock control 550 is available to users using the PSTN to user interface 560 . Inductor coil 520 couples the DC loop current, allowing normal use of the wired telecommunications equipment/system without interference or influence during data transmission using the out-of-band modem.

Additionally, methods for collecting and transmitting data from the data collection facility 120 are provided. First, analog and digital data are detected at a first location. Subsequently, the analog data is converted into digital data. The digital data is processed into a desired format and stored in a memory device. The processed digital data is sent over a wireless network to a remote device or location. In another embodiment, the sending step is performed on a wireless network control channel or short message service using GSM, PACS, FDMA, CDMA or TDMA digital technology.

In another embodiment, data from the optical meter reader microprocessor 340 may be sent wirelessly to the data collection device on an unlicensed radio frequency band. As previously described, data can be transmitted from the meter reader 300 to the data collection device using an LC or SAW transmitter circuit.

Additionally, a method is provided to monitor utility data for a conventional utility meter having a dial. First, a radiation beam is emitted from a radiation source and is reflected by a reflecting device onto a turntable. The turntable then reflects the beam back to the reflective device, which in turn reflects the beam towards an infrared detector where it is detected. The number of rotations of the turntable is counted from the number of times the infrared beam is detected by the detector. The meter reader includes algorithms to prevent misreading operations caused by sunlight, other forms of optical interference, or reverse rotation of the meter.

In another embodiment, a method of transmitting a sequence of data over a personal communication system transmission protocol is disclosed. As mentioned above, the PCS transport protocol includes several operating standards. These standards include Global System for Mobile Communications (GSM) technology networks, Time Division Multiple Access (TDMA) technology networks or Code Division Multiple Access (CDMA) technology networks, Frequency Division Multiple Access (FDMA) technology networks and Personal Access Communications System (PACS) technology networks and more. These technical networks all employ a type of digital control channel to direct traffic to the correct location. Typically, a control channel is used to transmit a sequence of data for voice or data communication to be directed to the correct destination through the personal communication system.

Short message traffic usually occupies part of the control channel and is used as an additional data path by data collection equipment on the network. A detailed discussion of the GSM and PCS transmission protocols can be found, for example, in An Introduction to GSM by Michel Mouly and Marie-Bernadette Pautet, Northern Telecom, Inc. Richardson, Texas, 1993.

The foregoing embodiments describe the use of digital control channels to send data from one device to another using drop and add packet techniques. The present invention uses the short message portion of the Personal Communications System transmission protocol to send data from one device to another. In general, the short message portion of the PCS transport protocol is the means of sending a protocol specific number of data characters to, from, and between mobile subscribers (MS), ie devices capable of sending via the PCS. Another difference between using the voice control channel and the short message service is that the frequency of data packets in the control channel of the short message service is lower due to the different operating protocols of the short message service adopted by each technology. For example, if a voice control channel is used, data can be sent to the data collection device and the remote device at a rate of 275 to 325 data sets per second, and the data collection device can respond and send data sets at the same (or similar) rate, This rate depends on the traffic of the control channel. In the case of short message services, data is sent at a rate of about 7 data packets per second.

In the present invention, data is requested and the requested data is transmitted using the short message portion of the personal communication system transmission protocol. As mentioned above, the short message portion of the personal communication system transport protocol is the means of sending a protocol specific number of data characters to and from a mobile subscriber (MS). In one embodiment, as shown in FIG. 8 , the data collection device 50 is a mobile user on a communication network, and a remote device 54 is capable of contacting the data collection device using a personal communication system network 52 . The remote device 54 can be accessed through the public switched telephone network 56 . Additionally, the connection of the remote device to the PSTN 56 allows data to be transmitted to and from the remote device 54 via the PSTN 56 . For example, when a utility company wants to receive meter usage data from its customers, the utility company may utilize remote device 54 connected to data collection facility 50 via public switched telephone network 56 . Remote device 54 requests data from data collection device 50 and when remote device 54 receives the data, transmits the data via public switched telephone network 56 to a utility company or data collection center, eg, using a modem.

If there is a data request, the remote device 54 encodes the request into a short message according to the personal communication system transmission protocol. The data can be assembled into a sequence of short messages using various known techniques. A technique for assembling short message service GSM control channel data sequences is shown in FIG. 7 . In FIG. 7 , the control channel shown has a downlink section 10 and an uplink section 12 . In another embodiment, the control channels may include a Standalone Dedicated Control Channel (SDCCH) and/or a Slow Associated Control Channel (SACCH). As mentioned above, a detailed discussion of the GSM and PCS transmission protocols can be found in "An Introduction to GSM" by Michel Mouly and Marie-Bernadette Pautet, published by Northern Telecom, Inc. Richardson, Texas, 1993. The control channel contains a protocol-specific number of characters per group. Each packet has a specific meaning in the protocol. In FIG. 7, data character cells 34 and 36 are used to send the desired short message from the remote device to the mobile user. The present invention is able to interpret requests sent in data character units 34 and 36 as short messages. Furthermore, the present invention is capable of constructing short messages containing requested data. When constructing the short message, the present invention can insert the requested sending data in the data. After adding the data as a short message, the data is sent from the data collection device 50 to the remote device 54 and the mobile user and from the mobile user to the remote device 54 and the data collection device 50 . As mentioned above, techniques for assembling, sending, receiving and interpreting short message type traffic can be adapted to accommodate other techniques.

Data requests are made by the remote device 54 and are converted into Short Message Service format, which are sent over the wireless PCS network 52 . The short message service data sequence is received by a base station controller (BSC) 60 which recognizes the data as a short message. BSC 60 sends short message to short message center (SMS-C) 58 through mobile switching center (G/MSC/VLR) 62. Then, using the wireless personal communication system network 52, a data request is sent from the SMS-C 58 to the data collection device 50 through the G/MSC/VLR and BSC. In response to the data request, the data collection facility 50 will interpret the request and compile the requested data. The compiled data is sent by the data collection device 50 using the short message service of the personal communication system transmission protocol. Similar to the data request, the compiled data is inserted as a short message into the control channel or other data sequence. It should be understood that data may be sent using multiple short messages in several control channels or other data sequences. The control data sequence is then sent as a short message over the wireless personal communication system network 52 via BSC 60 and G/MSC/VLR 62. In transmission, BSC60 recognizes the sequence of control channel data as a short message and sends this sequence to SMS-C58. The compiled data is then sent as a short message to a remote device 54 using the wireless personal communication system network 52 . The remote device 54 receives and interprets the compiled data. As previously mentioned, the assembly and disassembly of transmission packets or other data sequences in the data request and control channels can be performed by data packet assembly and disassembly techniques or standard SMS protocol techniques.

While the following description describes remote device 54 requesting data from data collection device 50, it should be noted that data collection device 50 may send data to remote device 54 without first being asked to send the data. For example, data collection device 50 may be a security device located in a residence. Once the data collection device 50 detects a breach of security, it sets the breach signal to the remote device 54 through the short message service part of the personal communication system transmission protocol using the method described above. Once the remote device 54 receives the security breach signal, it takes further security measures, such as notifying law enforcement personnel.

In another embodiment as shown in FIG. 6 , the data collection device 101 includes a device for performing data marking on collected data. Data/time stamping device 108 is an electronic device that provides a time relationship for collected data. As data is received from the meter or device 100, the data/time stamping device 108 electronically designates for each data reading the date/time the data was collected. Collected data and its associated data tags may be stored on a data collection device, such as electronic storage, for later retrieval. Thus, data saved for later retrieval can be used to make usage lists reflecting the amount and time of usage or compilation and saving of data. This type of usage list is useful when compiling electricity consumption data for a residence or business.

Additionally, the data/time-stamping device 108 is capable of adjusting data collection parameters such as collection frequency, associated time-stamping and consumption notifications, and the like. For example, remote device 140 may instruct data collection device 101 to collect data at hourly intervals and to stamp the time/date of each reading as it is taken. In addition, the remote device 140 may instruct the data collection device to discontinue all power to a location if a predetermined consumption is reached or in the event of a load shedding, on a predetermined basis as agreed upon by the utility company and the utility customer , or simply cut off power to unnecessary energy-consuming devices.

The data collection device 101 may also include a short message controller 109 . The short message controller 109 is capable of interpreting short messages received from the remote device 140 . The short message controller 109 can also instruct the data collection device 101 to perform several data collection functions, such as collecting data and retrieving saved data, etc. Once the data collection device 101 has performed the required functions, the short message controller 109 can construct a short message containing the requested data. The short message constructed by the short message controller 109 can be sent on the short message service part of the transmission protocol of the personal communication system.
