网络控制系统的连锁失效影响分析

Chain failure impact analysis for network control system

文章针对网络化控制系统中一个小的软件失效,通过网络交互引起整个系统崩溃的连锁失效现象进行研究;通过借鉴拓扑网络的研究方法,建立了网络化控制系统的多层网络拓扑图构建方法;利用网络拓扑结构建立了网络化控制系统的相互依赖原则,并对其相互依赖性的特点进行了分析;最后利用网络拓扑结构分析了连锁失效的特点及其相互依赖表现。

This paper studies the phenomenon of chain failure of network control system caused by a small software failure resulting in the crash of whole system due to network interaction.Based on the research methods of topology networks,a method to construct the multi-layer network topology for the network control system is proposed.The interdependence principle of the network control system is established based on the network topology structure,and the characteristics of the system＇s interdependence are analyzed.Finally,the features of chain failure and its interdependence are described by using the network topology structure.
