A Mixed Expert System for Fault Diagnosis
Because of the high structure complexity and variety of working condition, it is greatly difficult to fault diagnosis for heavy machines. This paper puts forward a method of fault diagnosis based on mixed expert system, which uses the rules and cases. The architecture and diagnosis flow of the system are both proposed. The knowledge database of fault diagnosis of heavy machine are mainly set up, including the rule database and case database which are respectively based on the Structure Fault Tree and breakdown maintenance record. Finally, the prototype system is designed.
