Application of Multi-sensor Information Fusion in the Intelligent Fault Diagnosis of Hydraulic System

For limitation of fault diagnosis methods in the engineering machine's hydraulic system,a fault diagnosis method based on multi-sensor information fusion was presented.The method utilizes fuzzy neural network as executive institution of fault diagnosis,and utilizes BP algorithm as training algorithm of network.By contrast the diagnosis result of an example,it indicates that using multi-sensor information fusion as fault diagnosis method is more accurate and reliable than using single information as fault diagnosis method in the hydraulic system fault diagnosis.
