摘　　要：研究目的:英标信号显示,除了机构外形尺寸与我国不同外,显示制式、显示灯光、表示器以及灯光和表示器组合、分歧道岔前显示序列等也与我国不同,在CTCS-2列控系统走出国门、要求与英标显示结合时,需要在充分发挥CTCS-2列控系统能力的基础上,合理确定其与英标显示中有关显示制式、显示灯光、路口显示序列等的结合设计方法。研究结论:(1)CTCS-2级列控与英标显示的结合方法包括:应选择英标四显示色灯信号机;根据地面码序一致性、获得前方经道岔侧向进路的时机不晚于CTCS-2或尽量不让CTCS-2级列控系统出现不必要制动为原则选择路口显示序列;应适配性调整CTCS-2级列控系统地面码序设置,采用在特定条件下译出特定低频码、对特定低频码进行区段占用锁频的处理方式进行接近控制;可根据道岔侧向进路限速分别采用MAY-FA4和MAR显示序列;(2)本研究结论可为CTCS-2走出国门、与英标信号显示结合当地化运用提供借鉴和参考。Research purposes: Signaling aspect following British standard is different from those following Chinese standard, not only in the ways of the shape and the size of the signal head, but also in the ways of the signal aspect, signal light color, signal indicator, the combination of the light color and the indicator, the signal aspect sequence approaching diverging junction. When CTCS-2 signaling system goes aboard and is needed to integrate with British signaling aspect, it is needed to define the design method to integrate it with British signal aspect, signal light color and the junction signal aspect sequence.Research conclusions:(1) The design method integrating CTCS-2 and the signaling aspect sequence following British standard includes: British-standard 4-aspects light signaling system should be chosen;The junction signaling aspect sequence should be chosen according to the principle of consistency of the ground code sequence, the moment getting the information indicating the diverging route no later than that of CTCS-2, or moment getting the information indicating the diverging route leading almost no unneeded braking;The ground code sequence should be adjusted accordingly, and the approaching controlling should be applied through decoding the certain ground code in certain condition and occupying-locking it;The MAY-FA4 or MAR can be adopted according to the speed limit of the diverging route.(2) The research results can provide reference for CTCS-2 outputting, its integration and localization with the British standard signaling aspect.
