地铁列车站台精确停车辅助系统研究

随着轨道交通管理技术与手段提升与加强,更加提倡运营管理与行车组织精细化管理。列车停靠的精确度直接影响列车运行组织的质量和安全性,也影响乘客乘车的舒适性。文章分析了列车停站误差原因,创新性地提出了一种地铁列车站台精确停车的辅助系统,分别针对ATO模式和手动模式下的列车停靠问题给出了相应的解决方案。当列车处于ATO模式,系统在列车制动模块中充分考虑因乘客上下车而动态变化的车厢质量;当列车处于手动驾驶模式,在站台上设置辅助进站引导系统,根据列车运行位置与速度,及时向司机显示最佳进站速度(定速点)。通过以上两个解决方案,实现辅助地铁列车站台精确停车,从而减少列车延误风险。

Research on Accurate Parking Auxiliary System of Metro

With the improvement and strengthening of rail transit management technology and means, operation management and fine management of traffic organization are more advocated. The accuracy of train parking directly affects the quality and safety of the train operation organization, as well as the comfort of passengers. This paper analyzes the causes of train stop error, creatively puts forward an auxiliary system for accurate parking of subway train platform, and gives the corresponding solutions to the problem of train parking in ATO mode and manual mode respectively. When the train is in ATO mode, the system fully considers the dynamic change of carriage quality due to passengers getting on and off passengers in the train braking module;when the train is in manual driving mode, an auxiliary station entry guidance system is set on the platform, and the best entering speed( fixed speed point) is displayed to the driver in time according to the running position and speed of the train. Through the above two solutions, the accurate parking of the auxiliary subway train platform can be realized, thus the risk of train delay can be reduced.
