Abstract: Electric energy expresses the product being that output is maximal in our country eletrotechnical instrument industry , the intelligence electricity meter becomes the main current that the electric energy meter develops already step by step with the fact that the high and new technology especially the electronic information technology fleetness develops. Design that the chip measures core by ADE7755 for electric energy originally, the monolithic machine is to control a chip mainly with AT89S52, electricity meter having designed that IC card-based one may pays wasteful single-phase intelligence in advance. The IC card adopt the Siemens SLE4442 logic to encrypt a card , safety is pragmatic. 12864 liquid crystal modules have provided limpid real time quantity of electric charge and usage information to the consumer. Adopt AT24C08 to be the data memory chip, timeliness having accomplished electric energy information stores and exchanges.
Keywords: Intelligence electricity meter, IC card, ADE7755 ,voltaic mutual inductance implement , C highway.
