自动进路原理中提前开放距离的最优化分析

Analysis on Clear-ahead Distance Optimization of Automatic Approach Principle

分析了提前开放距离对自动进路以及运营效率的影响,以CBTC制式为基础,本着运营效率最大化的原则,综合考虑传输延时、道岔转动时间、制动延时影响因素,详细阐述了提前开放距离的最优测算原则,最后对提前开放距离在轨道电路制式下的最优化应用进行了介绍。

This paper first analyzed the impacts on automatic route and revenue service efficiency by clear-ahead distance.Then based on CBTC system,with the principle of making the revenue service most efficient,and taking the affecting factors of transmission delay,time of switch moving,braking delay into account,analyzed how to measure and calculate the best clear-ahead distance in details.Finally,introduced how to apply the best clear-ahead distance on the track circuit system.
