指挥控制系统故障诊断专家系统的设计与实现

以专家系统理论为基础,针对某指挥控制系统的组成和下属工作站的结构特点,分析了该系统故障发生和故障传播的机理,应用故障树分析法,建立起系统的故障树。研究了故障的知识获取和表示方法,推理策略和推理机的构建。应用面向对象技术,构建了一种基于层次诊断模型与故障树分析法相结合,融经验诊断和原理诊断为一体的故障诊断专家系统。

Design and Implementation of Fault Diagnosis Expert System of Command and Control System

Based on theory of expert system,this paper analyses fault and its propagation mechanics of a command and control system according to the system composition and its branch workstation structure characteristics.Based on the fault tree analysis method,a fault tree to the system is established.The paper explores knowledge acquistion and representation method,reasoning strategy and construction of reasoning engine of the fault tree.On object-oriented technology,a kind of fault diagnosis expert system,which combines experience diagnosis and function diagnosis into one,is constructed based on combination of hierarchical diagnosis model and the fault tree analysis method.
