边界转换站临时限速优化方案研究

Study on Optimum Proposal for Temporary Speed Restriction in Boundary Interchange Station

文章结合客运专线临时限速服务器工程实施实践,对特定条件下CTCS-2级列控边界转换站中既有线提速方式、客运专线CTCS-2级未配置TSRS方式、客运专线CTCS-2级配置TSRS方式时的3种临时限速运用场景分别进行了分析,提出了通过修改相应应答器组数据包或在特定范围强制固定限速的2种优化方案,有效防止了动车组在跨越不同临时限速设置方式的区域时发生超速和制动的风险,可作为存在上述特定场景工程的解决方案。

Based on engineering practice of temporary speed restriction server,an analysis has been made on three temporary speed restriction application conditions of speed raising mode of the existing railway,CTCS-level 2 mode without TSRS for Passenger Dedicated Line and CTCS-level 2 mode with TSRS for Passenger Dedicated Line in boundary interchange station with CTCS-level 2 train control under certain conditions.According to analysis result,two optimum solutions have been put forward.One is to modify data package of the corresponding responder group,the other is to enforce the fixed speed restriction in certain range so as to avoid the overspeed and braking risks of train in speed restriction section,which can be a solution of such special case mentioned above.
