Cao Song-jie · Jisuanji fangzhen · 2008
For the fault diagnosis problem of complex system which has multiform architecture,time-varying character and coupling components,a causality mapping net methods based on multi-sensor fusion was proposed.By means of timing data mining,a fast mapping net with cause layer and effect layer was realized firstly.Then the node connection intension was defined by causality-degree.Afterwards,the fault position was located by rely-degree and the fault influence was predicted by effect-degree.An application example demonstrates the method has advantages such as simple mechanism,fast arithmetic and visual result.
