摘　　要：根据供电单位的要求,设计专门用于供电监测与报警和防止盗电行为的系统。系统基于电力线载波通信技术,采用串行数据的异步半双工通信方式,以AT89C51单片机最小系统为控制核心,LM1893为数据收发核心,采集监测各电能表的用电量信息,并对盗电和其他异常情况(电力线损坏等)进行报警。This paper introduces a monitoring system used to monitor the power consumption and to prevent the stealing of power. The system is based on the power line carrier technique, and is operated in the asynchronous half-duplex communication mode. A AT89C51 single chip＇s minimum system is used as the core of the system, and LM1893 is used to receive and dispatch the data of the power meter and the alarm signal.
