一种复杂系统的快速故障诊断方法

A Fast Fault Diagnosis Method for Complex System

摘要:

针对复杂系统故障诊断效率低,通用性、扩展性差等问题,提出并实现了一种基于灵巧故障树的快速故障诊断方法,首先通过诊断节点生成算法建立故障诊断树的关系,然后运用数据库技术对知识库进行处理,最后采用图形界面实现人机交互；该方法将故障树、数据库和虚拟界面进行融合设计,实现了故障的快速诊断和推理的动态更新,并在多型火炮控制系统的故障诊断中得到应用,取得了重大效益。

Abstract:

For the efficiency of fault diagnosis in complex systems is low, and poor universality and expansibility,a fast fault diagnosis method is proposed and realized based on the smart fault diagnosis tree. The framework and relationship is built through the generation algotithm of diagnostic nodes,then the knowledge base is processed on data base,Human-Computer Interaction is realized by the graphical interface. To achieve the fast fault diagnosis and the dynamic data update,they are fused with the fault diagnosis tree、the data base and the Virtual Interface,the method is used for the fault diagnosis of several gun control systems,and it has great benefits.
