Abstract : The basic concept , main advantage , architecture , method and application of multi2sen2 sor data fusion are described. Data fusion is the process of combining , correlating , and associating data f rom multi2sensor or other information sources to identity estimation and assessment of situations. Some general problems on fault diagnosis are int roduced. The process of data fusion of fault diagnosis are also int roduced. Their specialty and the layered fusion architecture fitting with fault diagnosis of cont rol system are analyzed , and an architecture of fault diagnosis which is based on the information fusion are deeply investigated.
Key words : 　　Information fusion ; 　Cont rol system ; 　Fault diagnosis
