摘　　要：介绍了低压电力线载波通信系统的基本概念,同时针对利用低压电力线传输数字信号的构想,选用国产的PL3200芯片,采用直接序列扩频,QPSK调制,CRC编码等技术自制了一个低压电力线载波通信系统,并进行了电力载波通信实验,结果证明利用220 V低压电力线进行数字信号的传输是切实可行的.This paper has introduced the basic idea of low-voltage power line carrier communication system. Simultaneously a Low-voltage power line carrier communication system has been made with the PL3200 of “Xiaocheng” company, which used QPSK modulating technology and CRC error-correcting codes. The experiment of power line carrier communication has been done by trying to transfer signal over the indoor 220V low-voltage power network. To sum up, the communication over the low-voltage power network is proved to be workable.
