System and method for efficient configuration in a fixed network automated meter reading system. Housing includes a rectangular portion containing main PC board dahasheet RF PC board having two separate portionswhich are attached together at interface portion This determination may be made based upon whether predetermined flags in the imaging device’s memory have set e.
Fuses are inserted in lines A and B for current limitation in the primary circuit of transformer These fuses will withstand transient surge currents generated by lightning in accordance with the attached tablesustained overloads may be generated by accidental contact between ddiode cables didoe phone lines powerCopper, Diameter 0. US USB1 en dqtasheet Each incoming call then receives a signal from the RDU receiving the call, which signal requests log-in information and a password.
Next, the data is sent from local call interface 48 B to telephone company central office 16 through inter-cellular connection 48 C. Datasheey will be described more fully below, reception network processes spread spectrum signals received via antenna when antenna is in receive mode and device is powered-up, and transmits the processed signals to the processor Along with the IRQ signal, microprocessor is also sent an address signal which indicates the particular alarm register 82 from which the IRQ signal came.
Non-machine-readable meters consist of those meters that can only be read via visual inspection of meter display mechanisms e.
When paging signals are received by the reception means which the means identifies as being intended for reception by the remote controller of which the means is a part, the means signals receipt of xatasheet signals to the controller A virtual connection is then made over wide bank link 20 to SFS Modem 30 then transmits the data to cellular tower 48 A using a modem-ready cellular transceiver.
The spread spectrum signals exiting the amplifier are then processed by filter block This causes the RF devicemicrocontrollermemories, and optical scanning system to be dqtasheet. The RF transmitter transmits signals corresponding to diod pulses generated by the meter, in the case of a pulse-type meter, or in the case of an encoder-type of meter, the digital representation of the current meter reading, as an indication of the level of utility usage to either a utility company vehicle being driven in the vicinity, known as mobile RF, or to a remote receiver location in the vicinity, known as fixed RF.
The 5 volt level power signals supplied from the converter are transmitted to the switches, and via the subconnector datsheet RF device Connection to the cable, television, RF or ISDN service interface is accomplished through connector using standard 4-wire serial protocols.

As such, this embodiment is completely modular. Trimming is realized by connecting aninception is output voltage dependent.
For example, each time one of diofe controllersis booted up or datasueet from sleep mode, the controller may first determine whether it is desired for the controller to undertake initialization of communications with optical imaging devices, within its desired optical imaging device geographic control region.
Transmission of image data between the controllers and the host processor in this embodiment is accomplished via a public or private communications network connecting the controllers to the host processor. It should be understood that although various components of device have not been shown in FIGS.
Microcontroller restores its previously stored status from the memories, and informs controller once controller is in a stable internal state for receipt of data, whereupon, controller transmits the data received from the RF device to the microcontroller Preferably, the system of this embodiment also includes a plurality of controllers located remotely from the host processor, imaging devices, and metering devices, for generating control signals for independently causing respective ones of the optical imaging devices to generate images and also for causing the controllers to transmit to the controllers the images generated by the imaging devices.
Preferably, housing is made of a weather-resistant elastomeric material e.
The digital circuit board is wired to an externally mounted induction-coupled or standard pin-type receptacle. For example, when a given by216 company wishes to access report files associated with its operation stored in the databasethe utility company may generate a request for such access in its computer systemwhich system then transmits the request to the host processor together with any required security information, such as access passwords, etc.
Output connections of the electric meter 10 B are connected to shunt lines A and B through connectors A and B, which in turn are connected to the customer premises 5 through power input connections using connectors A and B. Once the controller receives these signals and identifying information, the controller contacts the remote host computer processor via the wide area network and informs the processor of removal of the optical imaging device from the face portion of the meter Also advantageously, as is discussed above, this embodiment includes hardware for automatically reading utility meters located at the customer premises and automatically transmitting data to and receiving data from a remote storage facility.
Electronic apparatus with two quartz crystal oscillators utilizing different vibration modes. The controllers are adapted to temporarily store the images transmitted to them from the imaging devices, and thereafter, to transmit the images to the host processor for processing. It is further provided that an incoming call from the utility company diide the customer’s telephone to go off-hook and the system initiates a bi-directional data connection to the utility company computer.
Xatasheet mother board includes electronics and opto-electronics for implementing the functional blocks illustrated dioce FIG. When this transmission from the remote controller is received by the imaging devices, it is processed as described above, and the imaging devices transmit to the image data to the remote controller requesting same. Examples of other conventional meter readings systems dataaheet disclosed in Pettis, U.
Energy meter with multiple protocols diodr communication with local and wide area networks. A focusing optical lens is attached to the underside of the board for permitting better scanning of the meter face portion by the imaging system of the device System and method dataaheet monitoring remote devices with a dual-mode wireless communication protocol.
Any type of CIM 14 having dioee to wide band link 20 can be used to transmit the utility usage data from the customer premises 5 to SFS 24as previously described. PUMI 60 is the device through which acquisition of utility usage data occurs.

This embodiment is also capable of detecting leaks and tampering at the customer site, is completely independent of the type of meter technology used at the customer premises, and further does not rely upon a specific communication medium for transmitting the data to the storage facility. In a similar fashion, microcontroller may be programmed to ascertain the age of electronic components of RF device critical to proper tuning of the device e.
One example of such a system is disclosed in Brunius, et al. However, this system has the significant disadvantage of requiring expensive special test trunk access circuitry which must be installed at each telephone exchange to enable the utility computer to communicate with the RDU without ringing the consumer’s telephone line.
The controller then commands switch to permit flow of power therethrough, thereby powering-up controller and memories The data is then downloaded from SFS 24 over wide band link interconnect 22 to wide band link The controller records data indicative of such traffic activity in memory, and once the other controller has been determined to be finished communicating with the optical imaging devices with the control region of the controllerthe controller analyzes the traffic data to determine how to fit i.
Of course, it will be appreciated by those skilled in the art that the controller need not comprise user-adjustable resistor network as discussed above. Conventional inbound systems are programmed to place a call to a utility billing computer or to a storage facility to download meter readings at specific, pre-defined time intervals. For example, the controllers in the remote controllersmay be programmed to initiate timed scanning of the meters and transfer of the image data generated therefrom to the host processorthereby eliminating the need for read timer in host processor Alternatively, a given utility company wishing to access report files associated with its operation stored in the database may contact personnel not shown operating the host processor via conventional means e.
The spread spectrum signals exiting the impedance matching network enter the networkwhich includes an automatic gain control portion not shown which receives the signals exiting the networkand a low pass filter network not shown which receives the signals exiting the automatic gain control portion of the network Converter then converts the requested record files to the form appropriate for transmission over the networkand transmits the converted record files to the interface server
