Abstract: After an analysis of the subway train’s running under moving block system, the dynamics mathematical model of subway train is constructed; The control between multi trains is discussed, the method of decreasing the headway and increasing the carrying capacity is discussed by using the event-based technology and formation theory to ensure the safety and to avoid the stop out of station, this method can take it easy to reconstruct the system and to increase the cooperation between subsystems. Take account of three trains, the control strategy of the following train is given, the velocity, accleration of the train can be adjusted according the safe distance between the successive trains and the distance which the train have run.

Key words: moving block system, event-based, formation, headway

摘要： 首先分析了移动闭塞条件下地铁列车的运行规律，建立了地铁列车的动力学模型，研究移动闭塞条件下地铁列车车组间的控制，采用基于事件的控制理论和编队技术降低列车间的最小追踪允许间隔，在保证不撞车以及尽量减少站外停车的前提下，提高地铁线路的通过能力，并且能够方便地实现系统的重新配置以及各子系统间的协调协作。以相邻的三列列车运行为例，研究在移动闭塞条件下后续列车的控制策略，根据列车的走行距离以及前后列车间所要求保留的安全距离，动态调整列车的运行速度、加速度。
