摘要
为探究适用于CTCS-3级列车运行控制系统的高速铁路闭塞分区划分方法,分析影响闭塞分区划分的因素,在确保列车运行安全的前提下,构建多目标策略下的CTCS-3级高速铁路闭塞分区划分模型,采用粒子群算法对模型求解,并优化了算法中的适应度函数.通过在京沪(北京—上海)高速铁路滕州东—枣庄区间的实例验证表明,文章提出的优化方法能够有效缩短行车间隔,对高速铁路闭塞分区的设计具有实际意义.
Abstract
To explore the high-speed railway block section partitioning method applicable to the CTCS-3 level train operation control system,this paper analyzed the factors affecting block section partitioning,constructed a multi-objective strategy based CTCS-3 level high-speed railway block section partitioning model,on the premise of ensuring the safety of train operation,used particle swarm optimization algorithm to solve the model,and optimized the fitness function in the algorithm.The case study on the Tengzhou East-Zaozhuang section of the Beijing Shanghai high-speed railway shows that the optimization method proposed in this paper can effectively shorten the train running interval and has practical significance for the design of high-speed railway block section.
