Study on Intelligent Fault Diagnosis Expert System for Radio Compass

In order to diagnose and obviate faults of the radio compass, an intelligent fault diagnosis expert system based on the PC/104 computer is presented in this paper. By using the technology of the blurring nerve network, the fault converse illation, knowledge database and so on, the system reliability and flexibility is greatly enhanced. The testing results illustrate the readings relative errors of the system data acquisition and parameter simulation are lower than 0.5%, the veracity of fault isolation is 96%, the direct current power <; 300 W, the alternating current power <;250W, the cost of this system is cheaper 80% than ever.
