Recently, the door of the Chengdu subway car suddenly failed, and the staff "professional version of the extreme operation" in 50 seconds, and quickly restored the normal operation of the train.

3月22日，记者从成都轨道集团获悉，3月20日早高峰，成都地铁7号线车门防夹功能启动出现故障，“00后”电客车司机邹浥源立刻按流程处置。此时，7号线电客车队长安羽帆得知消息，也赶往现场进行故障处置指导，协助邹浥源成功将故障车门关闭、隔离。整个过程步骤紧凑、操作快速，全程仅用了50秒。

In the process of disposal, Zou Huyuan "finger and mouth" according to the specification, confirm that the door number is correct, and check that the door slot and door frame are free of foreign objects. After the disposal was completed, he immediately ran back to the driver's cab, and after confirming the safety, he closed the train with the station "okay" signal, and An Yufan and the station attendant Han Baicun returned to their posts after completing the follow-up work.

Zou Huyuan said: "Unexpectedly, this process was filmed by netizens and continued to become popular on the Internet. The staff's quick response and professional homework made netizens feel full of security. ”

Zou Huyuan "fingers and mouths" at work.

Whether it is Zou Huyuan's "gesticulating" in the video, or the subway platform being "pointed" by the driver, in daily life, everyone may be curious, what is the staff doing "pointing"?

According to the relevant person in charge of Chengdu Rail Group, this is one of the standardized processes of subway staff's operation, "finger and mouth call", that is, with fingers, mouth, ears, and heart.

Finger mouth call is a visual and auditory double confirmation mechanism, through the unified operation process and requirements, so that the staff can maintain a high degree of concentration in the operation process, avoid the possible misjudgment of a single sense, and reduce the potential safety hazards caused by negligence.

Take the driver's finger call as an example, when the door is opened, the driver gets off the station and is in the end door, points to the first door with two fingers, confirms and shouts, "screen door, door open"; When it is time to close the door, shout "Close" and press the close button; After the door screen door is closed, carefully check the gap, and finger the mouth and shout "the door is closed, the screen door is closed, the gap is safe".

In addition, in addition to the train driver, other professional staff will also use their fingers to ensure that the operation process is standardized:

The station attendant calls with his finger and mouth to confirm the corresponding door number of the passenger who is being connected.

The dispatcher of the depot calls with his fingers and mouths to confirm the arrangement and approach of the trains; The attendant calls out with his fingers and mouths to confirm that the approach of the field section is arranged correctly; The station attendant calls with his finger and mouth to confirm the corresponding door number of the passenger who is being connected.
