基于无线通信实现方式的PLC网络研究

Study of PLC Network based on Wireless Communication

针对PLC控制系统在工业领域中的应用需求,分析了PLC-DCS控制网络结构,对比总结了三类PLC网络的无线通讯实现方式;通过对不同类型实现PLC无线网络的硬件拓扑结构和组网要点的分析,总结了各种方式的应用特点,并比对了它们的适用场合及局限性,以便针对不同PLC的无线通讯模式,进行具体方案的设计。

This article analyzes the requirement of PLC-DCS and summarizes the three methods to accessing PLC by wireless contrastively in the view of the growing requirement of conlmunication in the PLC Network. Based on that, this paper gives discussion about the main techniques of maintaining the wireless access to PLC. By analyzing topological structure and implementation characteristics, the advantages of these techniques were expatiated. These analyses could help designer to devise a feasible wireless PLC network.
