Research on fault diagnosis method of scraper conveyor

In order to improve the accuracy of the scraper conveyor diagnosis and reduce the accident rate，this paper analyzed the common faults of the scraper conveyor，studied the fault classification of the scraper conveyor based on the support vector machine，and introduces the fault data processing of the scraper conveyor.The method and the fault diagnosis process based on SVM were selected.The parameters of support vector machine were selected.The optimal parameter model of the model was obtained by grid search cross method.The model was used to predict the fault data of the scraper conveyor.The combination of support vector machine and grid search cross method could effectively diagnose the failure of the scraper conveyor.
