| 摘 要： | 以故障诊断的理论和方法为基础，综合运用人工智能、数据库理论、模糊理论对复杂电子设备的故障诊断问题进行了研究，提出了一种基于数据库的专家系统故障诊断的方法，设计构造了诊断专家系统的整体框架，在系统实现中，采用隶属函数来反应故障对象特征的模糊性和模糊关系，基于关系数据库进行知识的模糊表达，用模糊性更新传播算法实现基于规则的模糊推理。

| Abstract: | The paper studies complex electric equipment fault diagnosis based on the theory and method of fault diagnosis by applying the theory of artificial intelligent ,database and fuzzy theory,and brings forward a way of developing a fault diagnosis ex-pert system based on database.It also gives out the frame of the system.In the imple-ment of the system,we use membership function to mirror faults' fuzzy and fuzzy con-cern,relational database to describe knowledge and rules,fuzzy renew algorithm to per-form rule-based inference. |
