摘　　要：电力线是目前分布最广的有线网络,利用电力线网络进行通信实现自动抄表是电力企业迫切需求,但目前电力线载波通信的现状不能令人满意,针对电力线载波通信的现状,本文提出了一种基于三态脉冲位移相位调制的电力线载波通信的调制解调方式,利用RS编解码技术,通过信号检测算法的研究,实现了在相对恶劣环境下的电力线载波通信,并将软硬件开发设计完成的DEMO(实验样品)板进行了实验室模拟环境下的测试,由测试结果可知,此方案基本能满足电力载波抄表的要求,对目前电力线载波通信的研究有一定的参考价值。Power line is the most widely distributed cable network. The use of power line meter reading is the urgent need of electric power enterprises, but the power line cartier communication status quo is not satisfactory. For power line carrier communications in the status quo, this paper proposes an approach based on displacement of three-state pulse-phase modulation of the power line cartier communication modem means the use of RS codec technology, through the signal detection algorithm, realized in a relatively harsh environment of power line carrier communications, and development of hardware and software design is completed the DEMO （experimental sample） board to carry out laboratory tests under simulated environmen. This program can meet the requirements of power line carrier meter reading, and have a certain reference value for the power line carrier communication research at present.
