宁启铁路电码化设计方案研究及应用

Research on Nanjing-Qidong Railway Coding Design Scheme

宁启铁路复线电气化改造项目采用基于继电编码的CTCS-2级列车运行控制系统,其电码化设计方案需同时满足动车组列车和普速列车的机车信号需求,设计方案较为复杂和特殊。针对股道侧向接车掉码、正线反向发车进路咽喉区无码、侧向接发车发码区段长度不足等具体情况,采用分析车载设备特性、电路特性、机车信号需求等研究方法,提出合理的设计方案。应用情况表明,提出的设计方案可有效解决地面电码化设备与动车组列车和普速列车车载设备不匹配的问题。

The double track electrification transformation project of Nanjing-Qidong railway adopts the CTCS-2 train operation control system based on relay coding. The coded design scheme needs to meet the locomotive signal requirements of EMU and the conventional speed trains at the same time, so the design scheme is relatively complex and special. In view of the specific situations of dropping codes on the flank receiving line, no codes in the throat area in the reverse departure route on the mainline and insufficient length of the coding section on the flank receiving and departing lines, the paper proposes a reasonable design scheme. The application shows that the proposed design scheme effectively solves the problem that the ground coded equipment does not match the on-board equipment of EMU and the conventional speed trains.
