The invention discloses a maglev train brake control system and a control method thereof. The control method comprises the following steps: the speed VO of a train when a brake instruction is receivedis obtained; electric braking is performed on the train according to a preset deceleration a, wherein the duration of the electric braking is T1; and friction braking is executed on the train until the train stops, wherein T1 is the duration required for reducing the train speed from V0 to a first preset value V1, and V1 is smaller than V0. Compared with the prior art, the method of the inventionhas the following advantages: only the initial speed V0 (the subsequent speed is a calculated value) when the train starts to brake is measured, accurate control over train braking can be achieved, so the problem that the reliability and stability of train braking are not high due to the fact that the speed measurement accuracy of the train is not high at a low speed is reduced to the maximum extent, the reliability of train stopping is improved, and the running safety and efficiency of the train are improved; and reverse operation of the train due to too long reverse traction braking time can be avoided.

    本发明公开了一种磁浮列车制动控制系统及其控制方法,包括如下步骤:获取接收到制动指令时列车的速度VO;按照预设减速度a对列车执行电制动,电制动持续时长为T1;对列车执行摩擦制动,直至列车停止;其中,T1为列车速度从V0降到第一预设值V1所需时长,V1<V0。由于采用了上述技术方案,与现有技术相比,本发明仅测量列车开始制动时的初始速度V0(后续的速度为计算值),即可实现对列车制动的精确控制,最大限度减少列车在低速下由于测速精度不高而导致的列车制动的可靠性和稳定性不高的问题,提高了列车停车的可靠性,从而提高车辆运行安全性及效率;另一方面本发明还可以避免因反牵引制动时间过长而导致的列车反向运行。
