应答器是CTCS-2及CTCS-3级列控系统重要设备之一,为列车运行安全提供至关重要的地面线路数据,结合目前已经实施的几条客运专线的应答器布置经验,从工程设计的角度,在区间反向应答器的设置、应答器最小组间距、股道中间DW应答器的设置、应答器距离BA最小距离、联络线多个里程系等几个方面对石武客运专线地面应答器的设置进行了研究,对相关部文标准中容易引起误解或没有明确规定的部分进行了阐述和细化,为石武客运专线地面应答器的设置提供了参考。 The transponder is one of the important equipment of CTCS-2 and CTCS-3 train control system. It provides vital ground line data for train operation safety. Combined with the transponder arrangement experience of several passenger dedicated lines that have been implemented so far, From the perspective of the setting of the transponder in the interval, the minimum group spacing of the transponders, the setting of DW transponder in the middle of the ballast, the minimum distance of the transponder from BA and the multiple mileage systems of the tie line, The setting of transponders has been studied. The parts of the relevant text standards which are easily misunderstood or not clearly defined are elaborated and refined, which provides a reference for setting up the transponder of Shiwu passenger line.
