Research on Fault Diagnostic Method Based the Fault Graph Model
In order to solve the problems that the fault tree model is too much simple and decomposing the fault graph is difficult in fault diagnosis of the complex systems,this paper presents the fault graph model which includes fan-in nodes,level nodes,directions,and no circles.The fault diagnosis and failure forecast principle is explained.Based on the model,fault diagnosis algorithm,failure effect forecast algorithm,building sub-tree database algorithm,building detected nodes path database algorithm are derived.
