摘　　要：以专家系统基本理论为基础 ,针对连续性生产流水线设备故障的特点 ,结合设计实例 ,详细论述了故障诊断专家系统的设计思路与方法。该专家系统具有交互式推理和自动推理的功能 ,并采用了基于故障树的搜索来处理精确推理问题 ,用模糊推理来处理不精确推理问题。该专家系统还引入了解释机制 。Aimed at features of equipment fault in continuous production line and combined with design example,based on basic theory of expert system,design thought and method of fault diagnosis expert system are described in detail.The expert system includes interactive inference function and auto-deductive inference function.Search method based on fault tree is adopted to deal with precise inference problem,and fuzzy theory is used to solve uncertainty inference problem.In addition,the expert system introduces explanatory mechanism,so inference has certain transparency.
