Troubleshooting and diagnosis of MVB line faults in HXD2 locomotive
In response to the MVB line fault problem in the HXD2 locomotive,we formulated a whole vehicle MVB network test plan by analyzing the MVB principle and combining with manufacturing to identify the cause of the line faults.Through on-site testing,the measurement of the near end crosstalk value of the MVB line was proposed,providing a new method for MVB fault diagnosis,which facilitates locomotive maintenance.
