Study on Intelligent Fault Diagnosis of a New Landing System

A study on the intelligent fault diagnosis of a new landing system is conducted in the light of such characteristics of a new generation of electronic information system as being computerized,digitized and integrated and in combination with the updating of maintenance means and the improvement of maintenance properties of this landing system.Based on the analysis of the system’s testing and maintaining properties,the fault tree of this landing system is built and the expression of knowledge is presented for building an expert system of intelligent fault diagnosis. Meanwhile,a dynamic reconfigurable knowledge base is constructed and a way of conversing from fault tree to knowledge is discussed.Furthermore,the expert system of landing system intelligent fault diagnosis is realized by means of VC and prolog.
