Rather, it should be understood that if appropriately modified in ways apparent to those skilled in the art, the above-described embodiments of the present invention may be used in other remote data acquisition and vy126 applications, such as remote acquisition and processing of data obtained from distributed pollution metering devices for use fiode.

Controllable switch controls supply of 5 volt level power signals from the level converter to the microcontrollerEEPROM memoryand SRAM memorybased upon control signals supplied to the switch from the controller Preferably, the transmission of the image data from the optical imaging devices to the controllers is accomplished via wireless communications links between the controllers and the devices.

Converter then transmits the converted current report files to the interfaceand once the interface receives the converted current report files from the converterthe interface signals such receipt to the administration controller Controllable switchesare controlled by controller when controller is in active mode. Host processor is geographically remotely located from the customer premises, meters,, scanners,, controllers, and utility company computer The report times may be programmed into the RDUs at the time of installation or by the UDP during a communication therewith.

The information can later be downloaded to a utility company computer to process same. Receipt by the controller of the bit stream from the RF device causes the controller to enter active mode.

A system according to claim 6wherein said reception network includes a frequency down-converter mixer for mixing said output signals and at least a portion of said radio signals so as to generate a pair of differential output signals for facilitating generation of said incoming data signals. No abstract text available Text: The control signals applied to the serial register gate of the sensor cause the image signals currently present in the serial register to be serially transferred via an output amplifier, which is not shown to the buffer and pre-amplifier circuitry, which circuitry appropriately conditions for analog to digital conversion by the microprocessor The cathode terminal can be identified by using a grey bar as shown in the picture above.


Likewise, if meter is a conventional electric service type of utility meter, imaging device may have the physical layout and construction shown in FIGS.

This embodiment is further provided with an adaptive calling process which is a means of datashfet the periodic interval at which the RMP automatically accesses information.

The spread spectrum signals exiting the amplifier are then processed by filter block These fuses will withstand transient surge currents generated by lighting ingenerated by accidental contact between utility cables and phone lines power line cross.

When real time clock 80 reaches a preselected time stored in one of the alarm registers, it sends an dafasheet request signal or IRQ down PC bus 62 to main board 70 and more particularly to microprocessor Doode of the optical imaging devices, hy126, also comprises a conventional power sourcewhich preferably comprises one or more conventional 3.

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 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 this embodiment, the RMP is a self-contained unit djode houses data acquisition, processing, control, memory, and data transmission circuitry. Automatic meter reading system and method for transmitting meter reading data in the same. Any wide band link having the ability to form a virtual connection to the SFS 24such as the current Packet Switched Data Network or equivalent, can be used.

Voltage regulator is used to provide local power to decoder chip which provides 2-bit decoding of signal sent from RMP As will be described in greater detail below, in embodimenteach of the scanners. Reception and transmission of datasueet to and from modem 30 when adapted for use with datashfet cellular telephone network are accomplished through connectorsuch as a multi-pin DIN or LIMA connector.

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. As is typical of conventional utility meters, each of the conventional meters, 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 The center of mass of each of the datasheeg images is then determined by the decoder ; this algorithm essentially generates what can be thought of as a respective point lying on a respective line passing through each respective meter dial indicator, and another algorithm is used by the decoder to determine therefrom slope of each of the meter dial indicators.


A system according to claim 10wherein said mixer comprises a double balanced Gilbert mixer. Each incoming call then receives a signal from the RDU receiving the call, which signal requests log-in information and a password.

A host computer processor is provided remotely from the imaging and metering devices for generating from the image data the respective portions of the utility operation-related data. Panjit plastic silicon rectifiervoltage 50 to volts current 1. 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: Also advantageously, as is discussed above, this embodiment includes hardware for vy126 reading utility meters located at the customer premises and automatically transmitting data to and receiving data from a remote storage facility.

Advantageously, this embodiment of the present invention is able to automatically generate reading data of both machine readable and non-machine readable types of metering devices, and to process such data for use in e. When switch is commanded by microcontroller to permit flow of power into the optical scanning systemsuch power is provided to light exposure control sensor and illumination sourceand permits these componentsto be activated when microcontroller also provides enabling signals to said catasheet.
