Study on Equipment False Diagnosis Expert System Based on Rough Set Theory

摘要

Base on the study on expert system design method and rough set theory, an expert system of equipment fault diagnosis has been established. The paper focuses on the description of designs on knowledge database, inference engine and explanation facility of the expert system and taking the air compressor vibration fault diagnosis as an example to analyse and validate. It shows that expert system can improve the system's performance, improve system's capacity and efficiency of diagnosis when rough set theory is applied to fault diagnosis.
