Abstract

A method and apparatus of the present invention includes a common node of a power line communications system for individually performing the register functions for a plurality of electrical metering devices operably connected to the node. The power line communications system includes at least one node having a plurality of registers, a respective one of which is associated with a respective electrical metering device. The electrical metering devices connected via the power lines to the node measure the power consumption of the electrical load associated therewith and transmit a signal indicative of the measured power consumption to the node and, in particular, to the respective register of the node associated with the electrical metering device. The node individually determines the power consumed by each electrical load operably connected to the node based upon the received signals. The results of such calculations are stored in the register associated with each respective electrical metering device. The stored results are also periodically transmitted to the system control center of the power line communications system. Thus, the register functions for a plurality of relatively simple electrical metering devices may be centralized at a common node.

Claims (7)

1. An electrical metering device comprising:
metering means configured to be coupled to a power line supplying power to an electrical load and for measuring the power consumption of an electrical load from the power line; and register communicating means for transmitting a signal, indicative of the measured power consumption to an external register located remote from said metering device such that the electrical metering device is free of register means for performing computations with the measured power consumption of the associated electrical load.
2. An electrical metering device according to claim 1 further comprising clocking means, operably connected to said communicating means, for producing, during a predetermined period of time, a periodic timing signal which includes the length of time remaining in the predetermined period of time, such that said communicating means sends the signal, indicative of the power consumption of the associated load and the length of time remaining in the predetermined period of time, periodically in response to the timing signal.
3. An electrical metering device according to claim 1 wherein said communicating means sends signals according to a consumer electronics bus protocol, and wherein said communicating means comprises means for formatting the signals according to the consumer electronics bus protocol.
4. An electrical metering device according to claim 1 further comprising means for displaying the measured power consumption of the associated load.
5. An electrical metering device according to claim 1 further comprising memory means for storing a measure of the power consumption of the associated electrical load measured by said metering means.
6. An electrical metering device according to claim 1 further comprising clocking means, operably connected to said register communicating means, for periodically producing a timing signal such that said communicating means sends the signal, indicative of the measured power consumption, periodically in response to the timing signal, and wherein the signal indicative of the measured power consumption sent by said communicating means is indicative of the kilowatt-hours consumed by the load.
7. An electrical metering device according to claim 1 wherein said memory means stores cumulative power consumption of the associated electrical load, and wherein the signal indicative of the measured power sent by said communicating means is the stored cumulative power consumption.
