After being translated into the data format appropriate for storage in the databasethe image data and associated scanner identifying information are then transmitted to the database which stores the image data and associated scanner identifying information.
System and method for efficient configuration in a fixed network automated meter reading system. Preferably, in this embodiment, each of the functional components of host processor illustrated block form in FIG. Preferably, switch is only commanded by the microprocessor to permit flow of power to the optical scanning system when it is desired to generate such image data. Mixer preferably is comprised within the same Motorola MCD chip comprising the low noise amplifierand receives as its down converter reference signal the datashee signal from the voltage controlled oscillator VCO comprised within PLL The report files thus generated are then stored in the database Remote monitoring system, remote monitoring terminal and remote monitoring terminal control program.
This causes controller return to active mode if it was previously in sleep mode, and controller controls the switchesto power-up the RF devicemicroprocessorand memories Otherwise, the controller maintains these components in a deactivated state.
The meter is read by inserting a data collection device, also known as a gun, into the receptacle. Additional modifications are also possible. Depending upon the state of the switcheither the output of the transmission network or the input of the reception network is connected to the antenna via impedance matching network e. Dioe for limiting demand from an electricity meter with an installed relay. All calls that come to the RDUs during the answer window, whether from the UDP or a third djode, are detected through ring detection circuitry, which then prevents the telephone from ringing inside the customer premises.
From the telephone datasjeet central office 16CIM 14 is used to access a particular RMP 12 at a particular customer premises 5. Power circuitry provides the RMP with remote disconnect capability and unlimited access to power even after the disconnection of electricity to the customer premises.
Thus, the frequency of the pulses generated by the first counter is equal to the frequency of the clock signals divided by the number of bits of the first counter. The controller then commands the processor again to switch the device into reception mode for another predetermined time period, whereby to determine daasheet an external device is broadcasting on the transmission frequency of the device Likewise, if meter is a conventional electric service type of utility meter, imaging device may have the physical layout and construction shown in FIGS.
System and method for controlling communication between a host computer and communication devices associated with remote devices in an automated monitoring system. Reception and dtasheet of signals to and bg126 modem 30 when adapted for use with a cellular telephone network are accomplished through connectorsuch as a multi-pin DIN or LIMA connector.
Trimming is realized by connecting an external.

For meters which indicate readings through a pointer and dial, a system which determines the meter reading from the location by26 the pointers on the dials is used, such as those designed to scan monochrome bitmaps for black and white levels. In this embodiment, RMP 12 is equipped with a modem 30 configured for use with a conventional telephone network which is adapted to transmit data to and receive data from the telephone company central office 16 through the utilization of telephone line Once the controller receives these signals and identifying information, the controller contacts the remote host computer processor via the wide area network eiode informs the processor of removal of the optical imaging device from the face portion of the meter The initial autonomous update mode time is programmed into real time clock 80 at the time of installation by1226 RMP 12 and can later be updated by means of placing such information at SFS 24 for download by RMP 12 during its next autonomous update mode session.
Preferably, this network takes the form of a wide area computer network, such as an Internet computer network, through which the controllers and the host processor exchange data via appropriate hardware and software e. Controller determines from the signals generated by the sensor if sufficient lighting conditions exists adjacent the meter face to enable generation by the sensor of such useful image data, and if such conditions exist, appropriate control signals are generated by the microprocessor and applied to the anti-bluming, image area, and serial register gates not shown of the sensorvia level shifters,respectively, for causing the sensor to generate transmit said useful image data to the micro-controller via buffer and pre-amplifier circuitry Preferably, networksare constructed such that together they attenuate signals more than 3 MHz outside of the band of 4.
A virtual connection is then made through wide bank link 20 to SFS Thereafter, the controllers and imaging devices are either commanded by the host processor to return to sleep mode, or automatically return thereto. The synthesizer includes means not shown for comparing the frequency of the pulses generated by the first counter with the frequency of the pulses generated by the second counter, and for generating a feedback error signal whose voltage level varies between 0 and 5 volts, and is proportional to the degree of difference that exists between said frequencies.
The Verma system comprises RDUs located at each customer’s premises for accumulating and reporting utility usage data from machine-readable utility meters at the premises, and a utility data processor or UDP located at the utility site for collecting the usage data sent from the RDUs over a conventional telephone network.
The cathode terminal can be identified by using a grey bar as shown in the picture above. Turning now to FIGS.
Multichannel intelligent electronic device with advanced communication capabilities. Once this has been carried out, the controller places itself into sleep mode, wherein it periodically powers-up the RF device to ascertain whether messages are being sent from any of the optical imaging devices over which the remote management controller comprising the controller has control.
Controller generates these control signals based upon control signals supplied to the controller from microcontroller via datasheet and subconnector Processor then retrieves the data in association with the respective identifying information, and transmits the data in association with the respective identifying information to the host processor via the system and network In a conventional outbound system, the utility company periodically calls each customer RDU to retrieve customer consumption data stored by the RDU.
The controller then commands the processor to spread spectrum baseband encode and transmit a data packet indicating that the optical imaging device of which the device is a part is going to begin broadcast. In this embodiment, RMP 12 is equipped with modem 30 configured to control an RF transceiver which transmits the data using radio frequency waves to either RF remote location 53 A, a fixed RF site, or vehicle 54a mobile RF site.

Controller is connected to synthesizer and to controller via subconnectorand may also be connected to processor The host processor preferably is also adapted to generate and store data files in which the respective portions of utility operation-related data are associated with respective utility customers.
The frequency of the pulses generated by the second counter is equal to the frequency of dztasheet output signal from the VCO divided by the number of bits of the second counter.
After receiving the signals processed by the reception networkthe processor spread spectrum baseband decodes the processed signals based upon the reference signals supplied to the processor from the clock and using conventional techniques well known to those skilled in the art, to convert the processed signals into a digital data bit stream representative of the information content of the spread spectrum signals received by the antenna and usable by the controlleroptionally performs conventional checksums on didoe bit stream to ensure that the bit stream consists of valid data, and transmits the bit stream to the controller via the connector 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.
