| Abstract: | Because of the limitation of the traditional forward reasoning method for fault diagnosis, a forward reasoning method for fault diagnosis based on BP neural networks is studied in this paper. The BP neural networks model used in fault diagnosis is constructed, and the process of forward reasoning is given.The validity and feasibility of the forward reasoning method for fault diagnosis based on BP neural networks are verified by the example of the faults in the ignition system of automobile engine. |
