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3种列车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。
关 键 词: 交通信息工程及控制;运行间隔;移动闭塞;算法

Abstract: The algorithm of train interval control under moving block was studied. Interval is the key issue to affect the safe operation of trains, and controlling the train interval effectively can ensure the safe operation of trains under moving block condition and achieve the goal of improving line capacity. Therefore, train interval control algorithm for three interval patterns under moving block were designed to achieve train security tracking operation in “hit a hard wall” and “hit a soft wall” modes and ensure train safety operation. By comparing the simulation of algorithm under “hit a hard wall” and “hit a soft wall” instance, it was found that this algorithm could ensure the tracking train to stop out of the forward train rear protection points safely. At the same time, “hit a soft wall” mode could improve line operations efficiently.
