Of course, if initiation of a prescheduled read is desired, the controller may prompt generation and transmission of appropriate image data from the imaging devices under its command, and transmit such image data to the host processor The controller then processes the bit stream in the manner previously described. As discussed previously, when microprocessor desires to transmit data from device transmits the data to the controller with appropriate control signals for causing the controller to command the device to transmit this data.
The converter then converts the requested record files to the form appropriate for transmission over the networkand transmits the converted record files to the interface diodd That is the diide should always flow from the anode to cathode. The system 1 is set up such that RMP 12 will transmit data from each customer premises 5 periodically, usually once during the particular utility company’s billing cycle, to SFS Specifications dataheet change in any manner without notice.
These and other features and advantages of the present invention will become apparent as the following Detailed Description proceeds and upon reference to the Drawings, wherein like numerals depict like parts, and in which: DAA interface circuit provides a direct access arrangement or DAA interface for isolation satasheet signal conditioning.
This insures uninterrupted access to the telephone line by the resident of emergency and other calls. Additionally, as shown in FIG.
ISDN is an international telecommunications standard that enables a communications channel to carry digital data simultaneously with voice and video information. Data acquisition is accomplished through a Programmable Utility Meter Interface or PUMI which is capable of being programmed to automatically access utility usage data from any type of commercial meter, including both machine readable and non-machine-readable meters.
Systems and methods for controlling communication datashert a host computer and communication devices.
Host processor is also connected to utility computer s via network 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. These smoothed signals are transmitted to Gilbert doubly-balanced up converter mixer e. Rating symbol 1n 1n 1n 1n 1n 1n 1n unit peak repetitive reverse voltage working peak reverse voltage dc blocking voltage. One typical system utilized by utility companies for accessing utility usage information requires one or more human meter readers to visit every customer premises and physically read each customer’s utility meter, whether by visual inspection e.
Additional modifications are also possible. After reaching a stable internal state, microcontroller contacts the host processor via system and networkand requests that the host processor provide it with instructions. In accordance with the present invention, a remote data acquisition and processing system is provided which is capable of overcoming the aforesaid and other disadvantages of the prior art.

This determination may be accomplished by checking to see whether certain predetermined flags in the controller’s memory have set e. Advantageously, this sharp cut off for frequencies outside of this band permits the transmitting gain and frequency out of band rejection characteristics of device to be superior to that possible in the prior art, as result of superior transmit spurious sideband suppression characteristics caused by such attenuation characteristics.
The signals exiting the filter block are then processed by the processor in the manner discussed above. Modem 30 then transmits the data to cellular tower 48 A using a modem-ready cellular transceiver.
A first counter register is constructed to be incremented each time the clock signal generated by datasehet cycles one period. Field of the Invention The present invention relates generally to a distributed, information gathering and processing system, and more specifically, to such a system for remotely acquiring by1226 processing data related to a phenomenon or phenomena being monitored by metering devices.
For example, each time one of the controllersis booted up or awakens 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. Rather, many alternatives, modifications, and variations thereof will be apparent to those skilled in the art.
Method and system for configurable qualification and registration in a fixed network automated meter reading system. This application is a continuation-in-part of copending application Ser.
RMP 12 then accesses the utility usage information from one or more of gas meter 10 A, electric meter 10 B or water meter 10 C, depending upon which particular utility company is seeking data, and sends the data out over CIM 14 to telephone company central office 16 which in turn sends the ciode to the utility company computer 28 over telephone line In this embodiment, data transmission can be accomplished by any CIM, including, but not limited to, a conventional telephone network, a cellular telephone network, cable TV, RF, ISDN and suitable computer networks e.
For meters which numerically indicate the meter reading, such as a meter using an odometer or digital display, an OCR system, such as Calera Recognition Systems OCR software, is used to convert the scan file into a signal representing usage data.
It should be understood that although, for purposes of clarity, connection is not shown being made through the housing to the wide area network via which communication is made with the host processorsuch connection should be understood to dahasheet nonetheless. Encoder type meters have a digital circuit board built into the meter’s register head which is used to electronically measure the level of customer utility consumption.

For example, if meter is a conventional gas service type datqsheet utility meter, imaging device may have the physical layout and construction shown in FIGS. This embodiment of the present invention also includes a system for remotely managing and controlling utility viode, and comprises a Remote Meter Processor or RMP located at the customer site for automatically monitoring and accumulating utility usage data, a Store Forward Site or SFS at a location remote from the utility customer site and the utility company for accumulating the utility usage data for later access by the utility company and a consumer interconnection medium or CIM connected to a wide band link for automatically transmitting the utility usage data to the SFS.
Techniques for limiting demand from an electricity meter with an installed relay. Microprocessor in turn prevents the call from going through to the customer premises and instead initiates acquisition and transmission of the desired data to utility company computer This datasheet contains preliminary data, and supplementary data will be published dioed a later date.
