摘　　要：针对用电高峰期电力供应不足的问题,设计了一种基于电力线载波的远程抄表智能限电电表。采用PL2000A作为电力线通讯模块,AT89C51作为控制单元,用电数据存储在24LC64E2PROM中。2组数码管显示单元分别用来显示正常用电量和最大限用功率。在用电高峰期,能根据电力部门的设定自动限制用户的用电功率。In order to solve the electricity problem which the electric power supply is insufficient in the peak consumption. We design the intelligent watt - huor meter which can be read long - distance through power line and can limit user＇ power. It takes PL2000A as the power line communication module,AT89C51 as control unit,and the users＇electricity datas store in 24LC64 EZPROM. Two groups of LED show the normal electricity consumption and maximum power which is distributed by the electric power department. During the peak time,it can limit user＇ power automically accord to the electric power department＇s distribution.
