DSS-Based Software Component Technology for Intelligent Malfunction Diagnosis of Military Navigation Equipment

The malfunction of navigation equipment monitor and diagnose is detected and diagnosed with traditional diagnostic instruments, which limits only on fixed objects because of its software lacks of ability of reuse and transplantation. So, put forward a software component plan for intelligent malfunction diagnosis based on DSS (decision supporting system). In this plan, combine DSS with software component, the software component technology of Expert System (ES) is applied to exploit the software of intelligent malfunction diagnosis system for navigation equipment. A structural intelligent malfunction diagnosis system is designed with DSS and artificial intelligence technology, the two expressional methods of knowledge such as facts and rules integrated. This system consists of ES, human-machine interface, main controlling computer, knowledge obtaining mechanism, system knowledge repository, dynamic database, fuzzy diagnosis module, NN repository and so on.
