Abstract
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.
