本文采用了一种符合人类维修专家故障诊断思路的方法,即层次模块化故障诊断法,来建造通用电子系统故障诊断专家系统。在系统建造中采用了框架和产生式复合知识表达形式表示系统诊断知识,采用了正反向混合推理、不精确推理及层次模块化诊断推理机制,并予具体实现。
In this paper, a method that is in line with the human diagnosis expert fault diagnosis method, that is, hierarchical modular fault diagnosis method, to build a general electronic system fault diagnosis expert system. In the system construction, the knowledge of system diagnosis is expressed by the framework and the production of complex knowledge representation, and the positive and negative hybrid reasoning, inaccurate reasoning and hierarchical modular reasoning mechanism are used to implement the system diagnosis.
