摘要
研究目的:复杂枢纽接轨车站之间的CTCS-3至CTCS-2列控等级转换方案一直是信号设计中的难点,有必要通过列控等级转换原理分析和实际工程案例的总结,提炼出通俗易懂的设计方法,为今后类似场景的工程设计提供参考和借鉴。研究结论:(1)CTCS-3至CTCS-2列控等级转换的基本条件为:YG-3/2应答器组距离出站口应答器组要大于450m,YG-3/2距ZX-3/2之间的距离应大于5s按线路最高允许速度的走行距离,RBC数据配置的范围必须从执行点向远方延伸至少一个常用制动距离;(2)两个CTCS-3级横列式车场在股道位置接轨,且两个车场分别属于两套RBC管辖时,可以在跨场进路上进行CTCS-3至CTCS-2等级转换,在跨场运行之后线路的正线上再进行CTCS-2至CTCS-3等级转换,实现两套RBC之间的切换;(3)当CTCS-3级与CTCS-2级两个横列式车场在股道位置接轨,且具有两条以上的跨场进路时,可以在两条跨场进路上分别进行CTCS-3至CTCS-2等级转换;(4)当CTCS-3级线路与CTCS-2级线路间的联络线长度不满足等级转换基本条件时,可以将CTCS-3至CTCS-2列控等级转换点设于CTCS-2级线路;(5)本研究结论可为跨线信号列控系统的设计提供参考。
Research purposes： There have been difficulties in signal design of CTCS -3 to CTC$ -2 level transition between the stations in complex hub, it is necessary to analyze the principles, summarize the practical engineering cases, and extract the user -friendly design methods for future similar scenarios to provide reference for engineering design. Research conclusions： （ 1 ） The fundamental conditions of CTCS - 3 to CTCS - 2 level transition is ： the distance from YG - 3/2 balise group to the CZ balise group should be greater than 450 m, the distance from the YG - 3/2 balise group to ZX -3/2 balise group should be greater than 5s traveled distance at maximum allowable line speed, the scope of the RBC data configuration should extend at least one braking distance from the execution point. （2） When two CTCS -3 yards in a row integrate and belong to two different RBC, the CTCS - 3 to CTCS - 2 level transition can be carried out on the cross- field line between the two yard, the CTCS -3 to CTCS -2 level transition can be carried out after running across the cross -field lines, then it achieves the RBC handover. （3） When two CTCS -3 and CTCS -2 yards in a row integrate and have more than two cross -field lines, CTCS -3 to CTCS -2 level transition can be carried on two cross - field lines. （4） When the length of the cross - field line between CTCS - 3 yard to CTCS - 2 yard does not meet the basic conditions of level transition, the CTCS -3 to CTCS -2 level transition point can be set on the CTCS -2 line. （5） The research conclusions can provide a reference for the signal design of train control system when there exists cross - filed hne.
