In operation, the utility company computer 28 places a call over telephone line 26 to telephone company central office Verma also discloses an encoder meter in which the need for a sensor interface is eliminated by providing the satasheet with built-in circuitry which encodes the utility usage information into an electrical signal which is read directly by the microcomputer.
Preferably, the utility computer includes means not shown for permitting the image data to be displayed in the form of one or more computer-generated images of the respective meter face or faces from which the image data was obtained.
Its blocking voltage varies from 50 volts 1n to volts 1n The up converted spread spectrum signals are then amplified preferably by 18 dB by a conventional pre-amplifierwhich amplified signals are then supplied to transmit amplifier Preferably, this is accomplished by providing host processor with a programmable meter read timing mechanism which generates controls signals for initiating scanning of the meters by the scanners at periodic time intervals, which time intervals may be selected by a user via the user interface or by appropriate control signals supplied to the host processor from the utility company computer sas will be described in greater detail below.
In operation, the utility company computer 28 places a call over telephone line 26 to the telephone company central office 16 which in turn uses telephone company wide band link access 18 to gain access to wide band link Pulse type meters, e. When the utility company wishes to make a demand read, as has been previously described, the utility company computer 28 initiates a call which addresses RMP 12 and the particular meter 10 A, 10 B or 10 C to be read. 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 components.
Also, relay is placed in the secondary circuit that supplies power to RMP Upon receipt of such signals from the microcontrollermicrocontroller determines whether the aforesaid conditions are present under which microcontroller is programmed to enter low-power mode. In this embodiment, administration controller may be programmed e. Without such enabling signals from these controllercomponentscannot become activated.
Such a function is not required when the other types of CIM 14 are utilized because the other types of CIM 14 each have a channel or line dedicated solely to the utility company. The controller then verifies any required security information, and if the requested access is authorized based upon such verification, controller commands database to transmit to the converter the record files requested by the utility In a conventional telephone network embodiment, the adaptive calling process is necessary to address the situation in which RMP 12 is attempting to datqsheet data in the autonomous update mode and telephone line 26 is unavailable because of use by the customer.

Preferably, this network takes the form of a wide area computer network, such as an Internet computer network, by16 which the controllers and the host processor exchange data via appropriate hardware and software e.
General purpose plastic rectifier 1n thru 1n vishay general semiconductor features. The information can later be downloaded to the utility company computer.
Preferably, networksare constructed such that together they attenuate signals more than diodde MHz outside of the band of 4. Thus, when the control signals supplied to the switch by the controller causes the switch not to permit flow of power from the source through the switchthe RF device is powered-down i.

Management of metal halide or nickel cadmium cell is accomplished by controlling circuit with datasheeet from power management system Referring now to FIG. That is the current should always flow from the anode to cathode.
Data are continually accumulated by the SFS from a number of RMP’s corresponding to a number of customers and is stored by the SFS until accessed and downloaded by the particular utility company for billing purposes.
Controllable switchesare controlled by controller when controller is in active mode. Power circuitry provides the RMP with remote disconnect capability and unlimited access to power even after the disconnection of electricity to the customer premises.
Housing includes a rectangular portion containing main PC board and RF PC board having two separate portionswhich are attached together at interface portion Systems and methods for recovering an out-of-service node in a hierarchical network.

If the type of meter to be read is an encoder meter or a non-machine readable type meter, FPGA initiates a read of the meter by accessing the current meter value using either the encoder connections or the optical scanner connections, whichever is appropriate, and such value is stored in a register 87 in FPGA DAA interface circuit provides a direct access arrangement or DAA interface for isolation and signal conditioning.
When activated, illumination source e.
Connection of modem 30 to PC- bus 62 is provided by PC- connectors System preferably comprises a conventional multi-element monochrome charge-coupled device CCD array sensor e.
Encoder type meters have a digital circuit board built into the meter’s register head which is used dataasheet electronically measure the level of customer utility consumption. It should be understood that although various components of device have not been shown in FIGS.
Filter circuit permits the higher frequency, lower voltage portion of the telephone signal, which contains the caller ID information, to pass on to the remainder of modem 30 circuitry while blocking the V ring portion of the telephone signal.
When the switch is set in this manner, a spring biasing force is applied datsaheet the end portion by the spring-loading mechanism not shown of the switchwhich biasing force is adapted to cause the end portion to drop down if the collar portion and thus, also the end portion is disengaged or otherwise moved from the meter face portion The mother board includes electronics and opto-electronics for implementing the functional blocks illustrated in FIG.
It should be understood that the foregoing discussion of the physical layout and construction of the optical imaging device was made with reference to use with a specific type of metering device i. The microprocessor can be programmed to cause the RMP to acquire and transmit data to the SFS at any specified predetermined interval.
