摘要 提出了基于实例的故障诊断专家系统方案:用产生式规则描述故障诊断单元知识,采用子空间划分法进行知识规划,基于实例的知识表达、推理机制和学习系统,推理过程中的"黑板法"等.目前基于实例的某型直升机故障诊断专家系统已经投入使用,能够适应当前该型直升机诊断、维修和排故的需求,具有良好的推广应用价值. A case-based fault diagnosis expert system project is presented, in which the knowledge is described by production rule and programmed by a method of sub-space dividing, and the knowledge expressing, the inferring mechanism and the self-recognition system are all case-based. The blackboard approach is used while reasoning. A case-based helicopter fault diagnosis expert system designed and realized as above has been used for helicopters of some type, which adjusts to the current demands of the helicopters maintaining and should be widely used in the helicopter fault diagnosis
