Abstract

In order to diagnose the faults in trubomachinery,a new type of diagnosis system based on Expert System(ES)and Neural Network(NN) is proposed.The NN diagnosis system is used to remember directly and associate faults happened before.The NN diagnosis system gives a set of candidate faults.The back reasoning mechanism of the expert system is applied to verifying these candidate faults.This diagnosis method is proved to be reliable and superior to the traditional ones.
