摘　　要：传统重载列车都是采用同一制动缸压力值对机车和各车辆进行制动控制,但当车辆分布在不同位置时,这种控制方式可能会导致车辆前后的车钩力不一致,大大增加了整列车的纵向力,对列车的运行安全造成不利影响。对此,文章提出了一种基于铁路地理信息的重载列车制动力差异化控制方法,该方法结合制动控制指令、列车的地理信息及各类传感器信息,可实现对不同位置车辆的制动缸压力的差异化控制。Traditional heavy-haul trains use the same brake cylinder pressure value to control the braking of locomotives and vehicles.However,when the vehicles are distributed in different positions,this control method may result in inconsistent coupling forces between the front and rear of the vehicle,greatly increasing the longitudinal force of the entire train and causing adverse effects on the safety of train operation.In this regard,this paper proposes a differential control method for the braking force of heavy-haul trains based on railway geographic information.This method combines braking control instructions,geographic information of the train,and various sensor information to achieve differential control of brake cylinder pressure for vehicles at different positions.
