Abstract

The application discloses a control method and device for preventing unrelieving braking, and a complete train. The method includes: detecting the pressure in the brake air storage cylinder of the train after the brake does not relieve the fault; if it is detected that the pressure in the brake air storage cylinder of the train is less than the first preset pressure value, then detecting The pressure in the brake cylinder; if it is detected that the pressure in the brake cylinder of the train is less than the second preset pressure value, the fault signal that the brake of the train is not relieved is cleared to control the operation of the train. Through the present application, the problems of cumbersome processing and low efficiency in the related art for unrelieving train brakes are solved.

Description

technical field [0001] The present application relates to the technical field of trains, in particular, to a control method and device for preventing unrelaxed braking, and a complete train. Background technique [0002] At present, rail transit vehicles will be blocked for traction when the brakes are not relieved. At this time, the driver will isolate the cock by cutting off the bogie and discharge the brake cylinder pressure corresponding to the bogie. When the cylinder pressure is below 40kpa, the failure of brake non-relief will be eliminated. Therefore, the driver only isolates the bogie and removes the cock, which cannot eliminate the brake non-relief fault, so that the train cannot be started. The fault can only be shielded by the brake non-relief fault bypass switch, so that the vehicle can start normally. Therefore, the operation is cumbersome and the efficiency is low, which may cause the risk of the train being delayed. [0003] Aiming at the problems of cumbe...
