Design and implementation of a certain type of naval gun fault diagnosis system based on fault tree

Expert systems;  Fault diagnosis;  fault tree;  Inference machine

Aiming at the abnormal state of a certain type of naval gun follow-up system, a fault diagnosis expert system based on fault tree is designed and implemented. Firstly, the composition of the expert system for naval gun fault diagnosis is given, and the design methods of knowledge base, reasoning machine and human-machine interface module are mainly introduced. According to the characteristics of the fault of this type of naval gun, the fault tree is constructed, and the knowledge base is built and updated. The inference machine adopts an inference strategy combining forward inference and inverse reasoning. Practice shows that the fault diagnosis expert system has beautiful human-computer interaction interface, convenient user operation, basic reliability of fault diagnosis results, and easy expansion of knowledge base.
