Application of Knowledge Storage and Diagnosis Expert System in Cryogenic System
摘要
Abstract
In order to realize intelligent fault diagnosis of the EAST cryogenic system, knowledge storage and diagnosis expert system of cryogenic system based on fault tree is proposed. According to the structure of fault tree model, knowledge storage based on level in the relational database is designed. Fault Tree Analysis(FTA) method is applied to build fault model and diagnosis inference, combined with reliability factor to assist uncertain inference, and the inference arithmetic is explained in detail through an instance. Simulation diagnosis results indicate that the expert system has a friendly interface, stable performance and reliable diagnosis results.关键词
