摘要
针对PLC控制系统在无线领域中的应用需求,研究了构建无线PLC控制网络的方案;基于对PLC-DCS控制网络三层结构的分析,总结出三大类PLC无线通讯模式,并根据对当今测控系统实现无线网络连接主要方式的分析,提出适合不同模式的无线解决方法;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,以帮助工程中针对不同PLC的无线通讯模式,进行具体方案的设计。
This article gives research on how to build a wireless PLC network in view of the growing requirement of wireless communication in PLC Network. By introducing the three layers of PLC--DCS network, a conclusion is drawn that accessing PLC by wireless should have three types. 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 and disadvantages of these techniques were expatiated. These analyses could help designer to devise a feasible wireless PLC network.
