| Abstract: | In view of the particularity of leakage fault diagnosis of an aerospace product launching system,this paper establishes the case knowledge base by the use of expert knowledge,sets up the graph theory model of its leakage fault diagnosis by means of the application of graph theory knowledge,on this basis,creates the tree and advances the "dichotomy" ideology in accordance with the information entropy theory to locate the position of fault components,and finally adds examples of successful diagnosis to the ca... |
