利用电力线载波实现远距离控制的研究

Research on Long-Distance Control by Using Power Wire Carrier Wave

电力线载波技术可广泛应用于同一变压器供电范围内各种自动控制系统，如每个建筑物内统一的防火系统、自动打铃系统、广播通讯系统、远距离电器控制等。从总体角度对一般电力线载波电路工作原理进行分析。

Power wire carrier wave technology was used varied auto-control system which was same power transformer Such as fireproofing and give an alarm power supply.system within many buildings.Auto bell system、Broadcast and communication system、long-distance control and so on.In this paper paper the theory of circuit about ordinary electric power wire carrier wave had been analyzed.there were a few practical circuits.
