As an example, the operation of the distributed locomotive electric brake control system is described in detail as follows:
under the automatic braking mode, when needing to apply service brake, the driver pushes the brake controller to the service brake area, and the brake controller converts the current signal information of 4-20 mA and the switching value information according to the current handle position information and sends the current signal information and the switching value information to the two CAN buses.

Once the pressure of the train pipe reaches the target pressure value, the pressure control module 1 of the train pipe automatically changes to pressure maintaining, and the train pipe maintains the current pressure unchanged. In the case where the trainline pressure control module 1 is in the normal state, the trainline pressure control module 1 does not operate. Once the train pipe pressure control module 1 finds a fault through self-checking, the train pipe pressure control module 2 automatically starts working by sending fault information to the CAN bus, and the working process is the same as that of the train pipe pressure control module 1.
It should be noted that the train pipe pressure control module, the brake cylinder pressure control module, and the individual brake pressure control module are independent from each other. The working process of the brake cylinder pressure control module and the single brake pressure control module is basically the same as that of the train pipe pressure control module, except that the brake cylinder pressure control module controls the brake cylinder inflation electromagnetic valve or the brake cylinder exhaust electromagnetic valve to act according to the pressure data information of the brake cylinder; and the independent brake pressure control module controls the independent brake charging solenoid valve or the independent brake exhaust solenoid valve to act according to the independent pressure data information.
