Research on Engine Fault Identification Method of Municipal Construction Loader Based on Decision Tree
Aiming at the existing identification methods in the municipal construction loader engine fault identification,there are identification results of low accuracy,and the identification process can not be achieved on the fault operation signal effective processing problems,the introduction of decision tree,to carry out the municipal construction loader engine fault identification method research.Using the decision tree,the classification of loader engine faults is realised;through the calculation of basic probability function,the allocation of basic probability of decision-making information fusion is realised,and the accurate identification of fault types is completed according to the allocation results.Through comparison experiments,it is proved that the new identification method can achieve accurate identification of loader engine faults in practical application,and in the process of identification,a clearer fault signal trajectory can be obtained,which provides a favourable basis for the operation and maintenance of loaders.
