股道靠标停车困难的CTCS解决方案研究

为解决CTCS中的股道靠标停车困难问题,从运营场景分析的角度,采用数学模型的方法分析股道正常靠标停车以及靠标停车困难的原因,内容涉及车载设备的控车逻辑以及停车标、应答器组和防护信号机的位置关系。以CTCS-2级和CTCS-3级线路为例,提出采用开口速度控制方式解决CTCS股道靠标停车困难问题。介绍开口速度控制功能的原理、一些现场应用场景以及所采用的冒进防护措施等,该方案对于CTCS各等级线路具有广泛的适用性。

Solution for difficulty of train parking at stop sign of station track in CTCS

In order to deal with the problem of difficulty of train parking at stop sign of station track in CTCS, from the view of operation scene analysis, this article used the method of mathematical model to analyze the reason about the normal train parking and difficulty of train parking at stop sign of station track, the content involved train control logic of on-board equipment, the position relationship among stop sign, responder group and protective signal. Taking CTCS-2 and CTCS-3 lines as an example, the article proposed the release speed control mode to solve the problems. The principle of release speed control function, some field application scenes as well as aggressive protective measures were introduced. The solution to the problem for each level of CTCS has extensive applicability.
