The invention discloses a brake control method and device for a long marshalling train, and relates to the technical field of railway train traction control, and the main technical scheme of the invention is as follows: in the process that the train is driven to a calibration position of a parking marker, activating a model correction function of a brake model on the train; a vehicle-mounted ATP is used for obtaining a target emergency braking intervention speed at the current moment, a target preset intervention speed grade corresponding to the target emergency braking intervention speed is determined, and the target preset intervention speed grade represents the numerical value for shortening the speed interval among the emergency braking intervention speed, the service braking intervention speed and the allowable speed of a train. Therefore, along with shortening of the distance between the running of the train and the calibration position, the target emergency braking intervention speed is reduced, the target preset intervention speed grade is correspondingly reduced, the speed interval among the three is shortened, the target allowable speed is indirectly increased, the limit distance close to the calibration position is shortened to the maximum extent for the long marshalling train, and the accuracy of the long marshalling train is improved. And parking marking operation is completed.
本申请公开了一种长编组列车的制动控制方法及装置,涉及铁路列车牵引控制技术领域,本申请的主要技术方案为:在列车驶向停车靠标的标定位置的过程中,激活列车上制动模型的模型校正功能,利用车载ATP获取当前时刻的目标紧急制动干预速度,确定其对应的目标预置干预速度等级,目标预置干预速度等级表征了在紧急制动干预速度、常用制动干预速度和列车的允许速度中三者之间缩短速度间隔的数值高低,由此随着列车行驶与标定位置之间距离缩短,目标紧急制动干预速度降低则相应地目标预置干预速度等级也降低了,上述三者之间速度间隔会缩短,间接实现抬高了目标允许速度,让长编组列车尽最大化地缩短接近标定位置的极限距离,完成停车靠标操作。
