Diagnosis of Distributed Test and Control Network Based on Minimal Fault Sensor

在分布式测控网络诊断中,为提高网络故障诊断的效率往往需要利用较短的故障搜索路径进行查找,为此,通过研究一类分布式测控网络拓扑结构图,基于网络中某些特定节点到其他节点的最短路径组合惟一性,提出以这些特定节点构建最小故障感知器的概念,研究表明利用最小故障感知器进行故障搜索具有较小的路径开销,由此给出基于最小故障感知器的分布式测控网络诊断新方法,研究了确定一类分布式测控网络最小故障感知器的算法,并利用一个分布式测试网络表明了该方法的可以应用实际的分布式测控网络诊断。

The problem to shorten the fault search path and enhance the search efficiency in diagnosing a distributrd test and control network is discussed.The topology structure of a class of distributed test and control hetworks is analyzed and based on the exclusiveness of shortest path set from some specific vertexes to others,the minimal fault sensors is built by using based on specific vertexes.The minimal fault sensors as a kind of fault searcher lower path cost.A diagnosis of distributed test and control network based on minimal fault sensor is suggested,and the algorithm for minimal fault sensors is given.The application result to in a distributed test and control network show.The feasibility and effectiveness of the diagnosis method.
