内容摘要：电能表是我国电工仪表行业中产量最大的产品，随着高新技术尤其是电子信息技术的快速发展，智能电表已经逐步成为电能表发展的主流。本设计以ADE7755芯片为电能计量核心,以AT89S52单片机为主要控制芯片，设计了一款基于IC卡的可预付费的单相智能电表。其中电流采样模块采用了电流互感器将大电流转变成为可以用来处理测量的小电流。IC卡采用西门子公司的SLE4442逻辑加密卡，安全实用。12864液晶模块为用户提供了清晰实时的电量和使用信息。采用AT24C08作为数据存储芯片,完成了电能信息的及时存储和交换。

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.
