The invention provides a railway locomotive automatic trailer control system and method. The system comprises a central control unit MPU; a traction control unit TCU; a brake control unit BCU; a microcomputer display screen DDU; a locomotive speed acquisition module; a coupler state detection module. The central control unit MPU is in two-way signal connection with the traction control unit TCU, the brake control unit BCU and the microcomputer display screen DDU, and is in one-way signal connection with the locomotive speed acquisition module and the coupler state detection module. When trailer operation is carried out, a locomotive is automatically controlled to run at a low speed, coupling operation is completed, the problems of low efficiency and low control precision caused by completely depending on manual trailer operation are solved, the working efficiency is improved, and the labor intensity of a driver is reduced.
Description
technical field [0001] The present invention relates to the technical field of rail transit, in particular to a railway locomotive automatic trailer control system and method. Background technique [0002] When a rail transit locomotive undertakes the task of freight or passenger transport, it needs to be connected to the coupler of the freight car or passenger car by its own coupler to form a train. The process of connecting is called trailer operation. When locomotive carries out trailer operation at present, all is to control locomotive speed by driver's operation driver controller and braking controller, realizes trailer. The usual operation process is that the driver operates the driver controller to pull the locomotive forward, and controls the speed not to exceed 10km / h, and usually trailers are carried out at 5km / h. After the two couplers are connected, the driver controls the brake controller to brake the locomotive to stop. Complete the trailer. Since the driver ...
