基于环网冗余网络的智能化变电站通信网络研究

摘要

介绍了 HSR 网络中双连接节点的基本结构以及对数据帧操作原理，对于HSR 数据帧格式和通信规则作出详细阐述。为了保证整个通信网络的传输性能，提出了一种对于复制帧及循环帧的接受和拒绝算法，并通过程序实现。最后，与其他方法进行对比，验证了该方法可提高查找数据帧的效率。HSR 网络的结构简单性，良好的经济性以及较高的可靠性，HSR 将成为智能化变电站中通信网络的主要研究方向。%This paper introduced the basic structure of DANH and operation of the data frame in HSR,and detailes the data frame format and communication rules.To ensure the transmission performance of the whole communication network.,we put forward an algorithm of accepting or rejecting the duplicate frames and the cycle frames,and work out the program implementation.Finally,compare it with other methods,the results show that this method is to improve the efficiency of search data frames.HSR network has structure simplicity,good efficiency and high reliability,it will become the main research direction of intelligent substation in the communication network.
