LOCOMOTIVE BRAKE CONTROL SYSTEM AND CONTROL METHOD

The present application discloses a locomotive brake control system and a control method, wherein the locomotive brake control system comprises a brake cylinder control system, a brake cylinder equalizing pipe control system and a changeover cock; when the changeover cock is in the cut-in position, if the locomotive brake control system is powered off or fails or is in a dead mode, the brake cylinder equalizing pipe control system outputs the brake cylinder equalizing pipe pressure according to the mechanical distribution valve pressure, and the brake cylinder control system outputs the brake cylinder pressure according to the mechanical distribution valve pressure and the brake cylinder equalizing pipe pressure; when the changeover cock is in a cut-off position, if the locomotive brake control system is powered off or fails, the brake cylinder control system outputs the brake cylinder pressure according to the mechanical distribution valve pressure and the brake cylinder equalizing pipe pressure from the lead unit.
