The Method for Diganisosis of System Fault Based on Nerve Net

HE Jian-feng (Nanjing Kangju Intelligent Information Technology Ltd. Company, Nanjing 210008, China)  
The method for checking fault and finding out fault parts using BP net is presented. BP net with four layers is adopted in the fault diganisos net. The first layer is the input layer, it's input and output is equal instant measured value of a system being tested. The amount of unit is the amount of the point being tested. The fourth layer is the output layer of the fault diganisosis net, it is a "and" logical unit. When system work normal, its output f i=1, when system appears fault, then f i =1 approximates "0". The trianing and diganisosis of the system can be accomplished using this method, and purpose of the system fault diganisosis is achieved.
