[0057]The present invention also provides a second embodiment. In the second embodiment, a distribution valve is used as the mechanical distribution valve 35. For the specific structure of the distribution valve, please refer to CN2017104076361. There are two working air cylinders 36, and the two working air cylinders 36 are connected with distribution valves.
[0058] All the other parts are the same as the first embodiment.
[0059] An embodiment of the present invention also provides a locomotive braking control method, using the above-mentioned locomotive braking control system, including the following steps:
[0060] Step 1: Detect whether the first pressure control valve 11 works normally; if it works normally, go to step 2; if not, go to step 4;
[0061] Step 2: Disconnect the channel connection between the redundant brake control module of the train pipe and the equalizing air cylinder 12, and connect the first pressure control valve 11 with the equalizing air cylinde...
