首发时间:2013-02-28
摘要:研究移动闭塞列车运行间隔控制算法。运行间隔是影响列车运行安全的关键问题,对列车的运行间隔进行有效的控制,能保证列车在移动闭塞条件下安全运行,同时可以达到提高线路运力的目的。为此,设计了移动闭塞条件下列车三种运行间隔模式的间隔控制算法,实现列车在"撞硬墙"模式和"撞软墙"模式下的安全追踪运行,保证列车运行安全。通过实例,对"撞硬墙"模式和"撞软墙"模式下的算法进行仿真比较,结果表明,所设计的算法能够保证追踪列车在前行列车尾部防护点外安全停车,同时"撞软墙"模式下线路的运营效率更高。

Research on Train Headway Control under Moving block
Abstract:The algorithm of train interval control under Moving block was studied. Interval is the key issue affecting the safe operation of trains, and controlling the train interval effectively can ensure the safe operation of trains under Moving block condition, at the same time, can achieve the goal of improving line capacity. To this end, train interval control algorithm for three interval patterns under Moving block are designed, to realize train security tracking operation in "hit a hard wall" and "hit a soft wall" mode and ensure train safety operation. By comparing the simulation of algorithm under "hit a hard wall" and "hit a soft wall" instance, algorithms designed can ensure the tracking train stops out of the forward train rear protection points safely, at the same time, "hit a soft wall" mode can improve line operations more efficient.
Keywords: Traffic information engineering and control Train interval Moving block Algorithm
