电力载波通讯是利用已经完善的电力线网络进行通讯,利用该通讯方式可以极大地降低通信线路布线成本,近年来随着通信技术的快速发展,特别是扩频通信技术和OFDM调制技术的出现使得电力载波通信有了很大的发展空间和发展前景。本文利用该项通信技术设计和实现了温度采集系统,系统主要由基于单片机的终端温度采集模块、上位PC机和载波通讯模块3个部分组成,终端温度采集模块与载波通讯模块B相连,上位机与载波通讯模块A相连,两个载波模块之间通过电力线相连。
Power line carrier communication is to use the perfect power line network to communicate, the use of the communication can greatly reduce the cost of wiring the communication lines. In recent years, with the rapid development of communication technologies, especially the spread spectrum communication technology and OFDM modulation technology makes the power Carrier communication has a lot of room for development and development prospects. This article uses this communication technology to design and realize the temperature acquisition system. The system is mainly composed of three parts: the terminal temperature acquisition module based on singlechip, the upper PC and the carrier communication module. The terminal temperature acquisition module is connected with the carrier communication module B, Connected with the carrier communication module A, the two carrier modules are connected by a power line.
