适用于单线铁路的CTCS⁃2级列控系统研究

Research on CTCS⁃2 Train Control System Applicable for Single Track Railway

本文提出一种适用于区间无码情况下的CTCS⁃2级列控系统,该系统对标准CTCS⁃2级列控系统车载设备进行适当修改、增加站间闭塞模式,并配套必要的列控系统地面设备,可实现动车组在区间不设置轨道电路的单线铁路或其他无低频码序的线路上采用ATP控车的运输需求。本文阐述站间闭塞CTCS⁃2级列控系统运营需求,并提出系统总体设计方案,研究各种运行场景下控车模式曲线,分析站间闭塞模式与其他模式的转入、转出方式,并给出系统建设方案,为单线铁路开行动车组提供全新研究思路。

This paper proposes a CTCS⁃2 Train Control System applicable to the condition that there is no low⁃frequency code in the section.The system modifies the on⁃board equipment of the standard CTCS⁃2 Train Control System appropriately,adds the Station Block mode,and matches the necessary ground equipment of the train control system,which can realize the transportation demand of the ATP controls EMU on the single track railway or other lines without low⁃frequency code sequence in the section.This paper describes the operation requirements of the Station Block CTCS⁃2 Train Control System,proposes the overall design scheme of the system,studies the curve of train control mode under various operation scenarios,analyzes the transfer in and out modes of the Station Block mode and other modes,and gives the construction plan of the system,which provides a new research idea for the EMU running on single track railway.
