Design of Mechanical Fault Diagnosis System for Multistage Conveying Device of Potato Harvester
A mechanical fault diagnosis system based on multi-source information fusion was designed to improve the efficiency and reliability of potato harvester.The system used sensors to collect vibration,temperature and other signals,and carried out noise reduc-tion and feature extraction through data processing module,combining SVM and DBN models for fault diagnosis.The test results showed that the system could accurately diagnose various faults such as conveyor belt breakage and bearing wear,and the diagnosis accuracy rate was as high as 96.7%.Compared with the traditional method,the accuracy of fault classification,false positive rate and diagnosis time are significantly improved,which proved the effectiveness and reliability of the method in practical application.
