针对机车信号绿黄掉白灯现象的电码化电路优化

Optimizing the coded circuit for the green-yellow-drop white light phenomenon in railway signaling systems

站场4股道发车增加方向口,受现场因素影响,发车进路距离发生变化,既有4G电码化电路可能引起机车信号绿黄掉白灯现象,本次股道电码化单端发码改双端发码工程,通过电路分析和掉码原因分析,以保证行车安全、最大限度降低施工难度、缩短施工工期为前提,确定可行的解决方案,将前期站场改造工程引起的问题一并解决。

Due to the influence of on-site factors,the distance of departure routes has changed,and the existing 4G coding circuit may cause the phenomenon of green,yellow,and white lights on locomotive signals.In this project,the single end coding of the station track will be changed to double end coding.Through circuit analysis and analysis of the reasons for code dropping,a feasible solution will be determined based on the premise of ensuring train safety,minimizing construction difficulty,and shortening construction period.The problems caused by the previous station yard renovation project will be solved together.
