The invention provides a train asynchronous braking control method and system, and the method comprises the following steps: receiving a braking command, and calculating the initial braking force values of a locomotive and a vehicle; judging the road conditions of the locomotive and each vehicle; measuring the ramp angle of the rail position where the locomotive or the vehicle is located, and calculating the weight of the dead weight of the locomotive and each vehicle in the braking direction according to the ramp angle; calculating the target braking force of the locomotive and each vehicle based on the brake cylinder pressure corresponding to the initial braking force value by combining the self-weight components of the locomotive and the vehicles; and the locomotive and the braking system of each vehicle execute asynchronous braking according to the respective target braking force. According to the asynchronous braking control method and system for the train, differential control can be conducted on braking force of the locomotive and the vehicles according to the road conditions where the locomotive and the vehicles are located, the coupler force of the train is reduced, and the running safety of the train is improved.
本发明提供一种列车异步制动控制方法及控制系统,其中,异步制动控制方法包括以下步骤:收到制动命令后,计算机车和车辆的初始制动力值;判断机车和各车辆所处路况;测量机车或车辆所处轨道位置的坡道角度,并根据坡道角度计算机车和各车辆的自重在制动方向上的分量;结合机车和车辆的自重分量,基于初始制动力值所对应的制动缸压力,分别计算机车和各车辆的目标制动力;机车以及各车辆的制动系统分别根据其各自的目标制动力执行异步制动。本发明所提供的列车异步制动控制方法及控制系统,可结合机车和各车辆所处的路况对机车和各车辆的制动力进行差异化控制,减少列车的车钩力,提高列车运行的安全性。
