摘要:

低压电力线传输特性的复杂性和传输过程中干扰信号的多变性,使其推广受到限制。文中依据高低频电路原理,结合现代通信与数字信号处理技术,设计了电力线载波通信的外围专用电路,包括发送驱动电路、耦合接收和AGC系统等,较好地解决了载波信号的接收与发送问题。

关键词: 电力线载波通信, 耦合, AGC系统

Abstract:

The complexity of transmission characteristic of low voltage power line and variability of interference signal makes its promotion limited.Based on the principle of high and low frequency circuit,contacting with modern communication and digital signal proecssing technique,This article describers The PCB circuits functions of the communication of electric power line,include amplifier,coupling,AGC system,etc.It solves the receiving and sending problem of the signal.

Key words: communication of electric power line;coupling;AGC system
