远动IEC 104通信通道冗余机制的探讨

Discussion on the Redundancy Mechanism of IEC 104 Telecontrol Channel

分析了远动网络通信冗余配置的需求,对通道冗余的机制进行了探讨,提出了链路冗余应用共享和链路应用均冗余的两种方案;对两种方案的连接切换、数据完整性、通信维护等关键技术和各自的优缺点进行阐述和比较,并结合工程实际分析了应用上的效果。

This paper analyses the redundancy configuration of telecontrol network, and discusses the the mechanism of channel redundancy. It also put forward two methods that they are shared application of link redundancy and every redundancy of link application. The article describes and compares some key features such as switchover, data integrity, and communication maintenance. The results of the application based on engineering practice are also analysed in the paper.
