MANAGEMENT CONTROL OF HOUSEHOLD APPLIANCES USING CONTINUOUS TONE-CODED DSM SIGNALLING

摘要

A system and method of communicating between a master and a slave device formanaging home energy are provided.A transmitter is operatively associated with one of a meter and a home energymanager for emitting a carrier signal at a selectedfrequency. A tone is superimposed on the selected carrier frequency andrepresents an operational energy cost level outputfrom an associated utility. A receiver receives the emitted carrier signalwith superimposed tone. A microcontroller associatedwith the home appliance then controls the home appliance in response to theemitted carrier signal with superimposed tone. Multipledistinct frequencies correlate to specific rates, and decoding or detectingthe presence of one or more tones can be used to representa binary number that allows the meter/controller to communicate "intelligence"with the home appliance.
