Research and Design of Fault Diagnosis System for Radar Countermeasure Equipment

针对雷达对抗装备的功能结构和故障成因具有层次性的特点,综合利用层次故障树分析法和专家系统的优点,研究设计了雷达对抗装备故障诊断系统。通过对装备的功能结构和故障特性的层次分析,在较小的范围内建立了故障树,并将故障树转换成二叉树来构建知识库,按照最小割集重要度大小的优先顺序进行诊断推理,实现了对雷达对抗装备故障的快速诊断。

According to the characteristics of the hierarchy in function and structure and the cause of fault of radar countermeasure equipment, combined with the advantages of hierarchy fault tree analysis and expert system, fault diagnosis system of radar countermeasure equipment is researched and realized. Based on the hierarchy analysis on function and structure and fault characteristics of equipment a fault tree hierarchy diagnosis model in relative small function range is established and converted to binary tree to establish repository, according to the magnitude of minimal cut sets ,diagnosis ratiocination is carried through and achieved to discover the fault of radar countermeasure equipment quickly.
