摘　　要：利用低压电力线载波技术来实现家庭自动化控制网络,其难点在于设计合理的调制解调和耦合方案。本文没有使用专用载波通信芯片,而以通用集成芯片设计出廉价实用的电力线载波调制解调模块及系统实现方案。本文主要简要地介绍了该通用电力线载波模块的工作原理与实现。The difficulties of using low voltage power line carrier communication technology to fulfill home automation control network are that how to design rea sonable solution of modulation demodulation and signal coupling. This paper use universal integrated circuit to design the cheap practical power line carrier co mmunication modulation demodulation module and the solution of home network syst em, instead of using special carrier chip. This paper mainly introduces the prin ciple of work and solution of the universal power line carrier communication mod ulation demodulation module.
