Research on Embedded Airborne Electronic Equipment Fault Diagnosis Expert System

The traditional airborne electronic equipment fault diagnosis systems have the disadvantage that the dynamic processing ability is low. The weakness of low effectiveness and accuracy is gradually exposed for it highly depends on the sample set and inherent module. The embedded airborne electronic fault diagnosis system built in this paper executes the dynamic processing by the subsystems, then summaries the information and makes the integrated diagnosis by the expert system which is embedded in the Flash in the microprocessor, realizes the real-time ability. The forward extract rule based on RETE algorithm is adopted in the expert system inference engine, which avoids the repeated match, reduces the time-complexity, and improves the efficiency.
