摘要
低压电力载波通信借助完善的电力线网络作为数据传输媒介,可以极大地降低通信线路布线成本,另外,扩频通信技术的应用使低压电力载波数据传输在抗干扰、抗衰减、可靠性等各项能力上都有了极大的提高。介绍了利用该项通信技术构建的温度采集系统,系统主要由终端温度采集模块、集中器和上位PC机3个部分组成,终端温度采集模块与集中器之间通过电力线传输数据,集中器与PC通过串行通信传输数据,文中主要讨论电力载波数据通信部分。
Depend on the developed power line network, the low voltage power line communication can lower the cost greatly. The application of SSC improve the transmission performances such as anti-interference, anti-attenuation, reliability etc. This paper introduced a temperature acquisition system based on this technology.The system consists of three parts： terminal module,remote unit and PC.The terminal modules communicate with remote unit by power line commtmication, and the remote unit communicate with PC by serial communication. This paper emphasizes on the front.
