| Abstract: | Taking tractor engine as object of study,it designed a set of tractor engine fault diagnosis system by using virtual instrument and CAN bus,and with necessary sensors.By comparing the parameter information of the sensor with the local parameter information database,the fault of the engine is diagnosed.The experimental results show that the system has good effect on the acquisition and diagnosis of engine fault signal,indicating that the system has high reliability and simple operation,and it can accurately detect the cause of starting fault. |
