Abstract
A metering system provides a measuring level with multiple meters and a collection level with multiple collectors. Each meter periodically measures a parameter, such as electricity consumption, and stores measurement information. Each meter periodically transmits its stored measurement information to a collector by a wireless signal. When a collector receives a transmission, it determines which meter sent the transmission, and then extracts unprocessed measurement information. The collector then processes the measurement information to generate a metered function, such as a load profile, a time-of-use profile, or a demand profile. The collector can compensate for missed transmissions and power failures. The metered functions for each meter are transmitted from the collectors to a monitoring station.
