Utility Network Communications Using Meter Identifiers

Abstract: An electronic electric meter for use in a networked automatic meter reading environment. The meter includes a meter microcontroller, a measurement microcontroller, a communication microcontroller and spread spectrum processor, and a plurality of other communication interface modules for communicating commodity utilization and power quality data to a utility. The meter measures electricity usage and monitors power quality parameters for transmission to the utility over a spread spectrum local area network (LAN) to a remotely located gateway node. The gateway node transmits this data to the utility over a commercially available fixed wide area network (WAN). The meter also provides direct communication to the utility over a commercially available network interface that plugs into the meter's backplane or bus system, bypassing the local area network communication link and gateway node.

High function, user configurable electricity meter

Abstract: The present invention, in one embodiment, is a method for measuring electricity usage that includes steps of: coupling a sensor (104, 106) to a power source (102); converting a signal from the sensor to a digital measurement signal (112); using a microcomputer (114) to determine quantities indicative of electricity consumption from the digital measurement signal (112); and using a nonvolatile, reprogrammable memory (120) coupled to the microcomputer (114) to control the microcomputer (114) in determining the quantities indicative of electricity consumption.
