好奇也别乱按!南京地铁重要提醒

每天坐地铁的你

是否留意过站台立柱上

带保护罩的红色按钮

它可不是什么装饰品

而是关键时刻能救命的

地铁紧急停车按钮（简称EMP） 

今天，我们就来

一次性讲清楚它的作用

看完这篇文章

你就会明白

它，可不能随便动

它长什么样？

地铁紧急停车按钮的结构主要分为三个部分。

最外层

红色保护罩（通常为镂空亚克力材质，需要用力按压才会破裂，防止意外触碰）

1

2

中间层

按钮本体（按下有明显卡顿感，松开后自动回弹）

底部

接线接口（连接着站台的信号行车控制系统）

3

它是如何工作的？一按就停车？

它的工作原理并不复杂，就像家里的电灯开关一样。按下按钮，就相当于接通了“紧急停车”的信号。

当你用力按下EMP按钮，它会立即向信号联锁系统发送“紧急停车”指令。信号系统会同步将这个指令传给正在进站、出站或站内行驶的列车，瞬间触发列车的紧急刹车系统，让列车能在安全距离内稳稳停下。整个信号传输过程几乎零延迟，只为最大限度保障人员与列车安全。

如果真的遇到紧急情况，该怎么做？

如果真的遇到万分危急的时刻，请记住这三步，才能真正发挥作用：

1

迅速找到离事发点最近的紧急停车按钮。

2

用力按压，确认按钮被按到底。

3

按下后，立即告知附近的工作人员，并原地等候专业人员处理。

特别警示：非急勿动！

非紧急情况下，绝对不能碰！ 一旦误触，后果不堪设想：

⚠️造成客伤：列车紧急刹车，车内乘客极易因惯性摔倒，甚至引发踩踏事故造成客伤；

⚠️运营延误：列车意外停车也会影响正常运营秩序，造成列车晚点；

⚠️承担法律责任：违规触碰者，或将面临行政处罚，情节严重的要承担相应法律责任。

希望大家看完这篇科普

能正确认识EMP

敬畏每一个应急设备

一起守护地铁出行安全

✨✨✨
