摘　　要：研究目的:到发线有效长是高速铁路的一个重要技术标准,它与土地资源利用、工程投资等密切相关。我国高速铁路到发线有效长度为650 m,主要依据16辆编组列车长度和安全防护距离设计。近年来,随着运力要求的不断提高,高速铁路需要开行更长编组的动车组,优化到发线有效长成为一个必须解决的问题。本文从车载设备的角度出发,通过分析车载设备控制逻辑,研究国内外其他列控系统的处理方式,提出一种高速铁路到发线有效长的车载优化方案。研究结论:(1)方案优化CTCS-2级控车目标点,可解决CTCS-2级对标困难的问题;(2)方案采用开口速度控制,地面设计不需变动,可充分利用到发线有效长;(3)方案优化CTCS-3级的冒进防护功能,可进一步提高开口速度控制的安全性;(4)本研究成果可为我国高速铁路到发线有效长的优化提供一定借鉴。Research purposes:The effective length of receiving-departure track is an important technical standard of high-speed railway,which is closely related to land resource utilization and project investment.At present,the effective length of receiving-departure track in high-speed railway is 650 m,which is mainly designed according to the length of 16 car marshaling train and safety protection distance.In recent years,with the continuous improvement of transportation capacity requirements,longer EMUs need to be put into operation,optimizing the effective length of receiving-departure track has become one problem that must be solved.In this paper,from the perspective of on-board equipment,by analyzing the control logic of on-board equipment and studying the processing methods of other train control systems at home and abroad,an optimization scheme for the effective length of receiving-departure track is proposed.Research conclusions:(1)The scheme optimizes the target point of CTCS-2 on-board equipment to solve the problem of accurately at stop signal in station.(2)The scheme adopts release speed monitoring,which can keep track design unchanged and make full use of the effective length of receiving-departure track on the premise of ensuring safety.(3)The scheme optimizes train trip protection of CTCS-3 system to further improve the safety of release speed monitoring.(4)The research results can provide some references for optimizing the effective length of receiving-departure track of high-speed railway in China.
