摘 要:常导高速磁浮是当前国内最成熟的磁浮技术,适用于中长距离、大运量快速客运,列车追踪间隔是编制和调整运营计划的基础,在保证列车运行安全前提下缩短列车追踪间隔是提高运营效率的关键。为缩短列车追踪间隔,文章研究了高速磁浮列车运行安全防护原理,分析了现行准移动闭塞追踪运行方式的局限性,建立了基于列车安全距离和间隔分区运行要求的追踪运行间隔模型,结合磁浮列车停车点步进控制的特点提出了一种用于列车追踪运行间距求解的离散表达式,并综合考虑正常和异常情况下的追踪运行场景建立了满足列车追踪运行间距的计算模型,得到了高速磁浮列车追踪间隔计算方法。在一定的追踪运行场景下的仿真计算结果表明,该方法对高速磁浮列车追踪间隔时间的优化效果十分明显,相较于现行的列车追踪间隔控制方法,在相同的工况下更有利于开展运营组织。Normal-conducting high-speed maglev technology represents the most mature maglev system currently available in China,suitable for medium-to long-distance,large-capacity and rapid passenger transportation.Since train tracking interval serves as a basis for preparing and adjusting operation plans,reducing train tracking interval is considered crucial to improving operational efficiency on the premise of ensuring the safety of train operation.Focusing on this topic,this study began with a research of the safety protection principles for the operation of high-speed maglev trains,and analyzed the limitations of train tracking operation in the current quasi-moving block mode.A tracking interval model was then established,taking into account safety distances for trains and the requirements for interval operation in blocking sections.Subsequently,a discrete expression for solving train tracking operation interval distance was proposed,which incorporates the stepping control characteristics of maglev trains at stopping points.Furthermore,a model for calculating train tracking operation distance was established,which considers train tracking scenarios in both normal and abnormal scenarios,thereby developing a calculation method for train tracking interval.The results of simulations conducted under specific train tracking scenarios show that the proposed method is highly effective in optimizing tracking interval for high-speed maglev trains.Compared to the current train tracking interval control methods,it offers more favorable conditions for organizing train operation under identical conditions.
