Corn harvester power train fault diagnosis system and method

The invention provides a corn harvester power train fault diagnosis system and method. The system comprises an acquisition module and a diagnosis module. The acquisition module is used for collectingparameter information of transmission components of a harvester power train to be diagnosed and sending the parameter information to the diagnosis module. The diagnosis module is used for establishinga feature matrix for indicating the working state of each transmission component according to the received parameter information, comparing the feature value in the feature matrix with the corresponding standard feature value in a pre-established standard feature matrix and outputting fault diagnosis results of the transmission components according to the comparison result. According to the system and method, the parameter information of the transmission components of the harvester power train is collected, the feature matrix is established, and the feature value is compared with the standardfeature matrix to obtain t
