Study to the Malfunction Diagnosis Expert System Based on the Malfunction Tree

The paper briefly introduces the basic structure of the malfunction diagnosis expert system in the braking system of mine hoist, gives emphatic narration to the foundation of knowledge base and the real- ization of reasoning machine. The malfunction tree analysis method is introduced while the knowledge base is founded, and the paper briefly narrates the process and method for founding the knowledge base by applying the malfunction tree. Rete matching algorithm is applied to design the program of reasoning machine, thus the reasoning effi- ciency increases greatly.
