多征兆模糊诊断知识表示及专家系统的研究

Study on the Expression of Multiple Symptom Fuzzy Diagnosis Knowledge and Its Expert System

介绍了一种旋转机械多征兆模糊故障诊断专家系统 ,研究了多征兆模糊产生式规则的诊断知识表示和以关系数据库为基础的知识库的建立与维护机制 ;利用ODBC技术实现了对知识库的访问和诊断推理。系统在满足对知识表示和推理模型的有效性和实用性要求下 ,具有构造简单 ,推理效率高等优点。

A kind of fuzzy fault diagnosis expert system of multiple symptoms based on database for rotating machinery was introduced. The expression of multiple symptom fuzzy diagnosis knowledge and the establishment of safeguarding mechanism of rule base has been studied. With the ODBC,the access to rule base and diagnosis reasoning can be actualized. The system is satisfactory to the knowledge representation and the effectiveness of reasoning model and practical requirement,its merits are simple to construct and of high reasoning efficiency.
