This paper describes the basic principles of artificial neural network(ANN) and fuzzy reasoning system,analyzes the design ideas of the fault diagnosis expert system based on artificial neural network and fuzzy reasoning system, and works out combined fault diagnosis method of ANN and fuzzy reasoning technology: fuzzy neural network method,in which ANN produces the reliability of fault emergence by processing part of the measured data so as to realize fault diagnosis of the system,while the fuzzy reasoning part presents the degree of faults by fuzzily expressing input and output and combining fuzzy neural reasoning to realize fault diagnosis.
