电力线载波通信技术因具有通信距离远、无需外接通信线路等优点而广泛应用。介绍了基于电力线载波通信技术的智能教室节能系统，并重点介绍了电力线载波收发器LM1893和单片机AT89C51在低压电力线上实现异步串行多机通信的硬件和软件设计方法。
- Abstract:
- Power line carrier(PLC) communication technique,possessing the merits such as long distance transmission and no additional communication lines,is widely used in many fields.An intelligent classroom energy-saving system based on PLC is introduced,in which PLC transceiver IC LM1893 and microcontroller AT89C51 are used to realize the asynchronous serial multi-microcontroller communication via low voltage power line, and relevant hardware and software design are given in this paper.
