在四显示自动闭塞区段由于线路坡度、机车牵引动力等条件的限制,经过牵引计算,需要在启动困难的地段设置容许信号,这就要求信号专业考虑增加容许信号点灯电路。容许信号增加后会出现通过信号机点灯与地面编码不一致的情况。针对这种情况,依据有关设计规范,提出具体的解决办法。 Due to the limitation of the line slope and locomotive traction power and other conditions, it is necessary to set the allowable signal in the difficult start-up area after traction calculation, which requires the signal professional to consider increasing the allowable signal lighting circuit. After the signal is allowed to increase will appear through the signal lights and ground coding inconsistencies. In response to this situation, according to the design specifications, put forward specific solutions.
