Construction and realization of an expert system for fault diagnosis of air-conditioners

The paper took air-conditioners as research object, first represented the overall structure of the expert system and the property detection system, set up the knowledge base with production rule and discussed the knowledge base management, set up the inference engine with uncertainty inference method, then developed an expert system for fault diagnosis of air-conditioners on its working condition, which can realizes fault diagnosis and maintenance consultation. Finally introduced the application method of determining the fault causes and gave the maintenance method through human-computer dialogue system.
