IEC 61850新型网络冗余报文捕获解析工具开发

Development of a New Network Redundancy Packet Capture and Analysis Tool for IEC 61850

以设计解析新型报文工具为目的,分析了网络冗余下的新型并行冗余双网原理,在解读新型报文格式的基础上,采用Wireshark网络开发包,基于Windows平台,结合GTK界面设计工具,开发出含有并行冗余双网的采样值报文捕捉、解析工具。并采用WinPcap库接口函数模拟装置发送报文,验证协议解析工具的可行性。结果表明,该解析工具能正确地分析数据包的负载内容,对IEC 61850第2版的推广具有重要意义。

To design a new packet capture and analysis tool, first of all, this paper analyzed the principle of PRP around with network redundancy. Then, based on parsing new packet structure, this paper developed the packet capture and analysis tool containing the sampling values of PRP in Windows platform, by using the network development kit Wireshark and combining with the interface design tool GTK. At last, the feasibility of protocol analysis tool was verified with using the interface function of WinPcap to simulate device to send packets. The results show that this tool can correctly analyze the load content of data packet, which has great significance to the promotion of the second edition of IEC 61850.
