基于故障树的某型装备故障诊断专家系统

Expert system of fault diagnosis for certain equipment based on logic coding of fault tree

基于故障树逻辑编码的某型设备故障诊断专家系统,用具有逻辑关系的数字编码建立故障树模型,再以故障树表形式表述专家知识,并通过故障树自动生成专家系统推理规则。该系统基于Visual Prolog编程语言,包括知识表示、知识库、推理和解释机制的设计。

For the expert system of fault diagnosis for the certain equipment system based on fault tree, the fault tree model was built up by using digital coding with logical relation. And then, expert knowledge was expressed with the form of fault tree, and the logical reasoning rule of expert system produced by fault tree automatically. The expert system is based on Visual Prolog language, this includes knowledge expressing, knowledge base, reasoning, and explaining mechanism.
