What is the function of the screen door system?

65438+1At about 4: 30 pm on October 22nd, the staff rushed forward to try to help out. After being sent to hospital for rescue, the passenger still died unfortunately. After this incident, it attracted the attention of the majority of passengers in Nanjing. Everyone wants to know whether the screen door of Nanjing subway has anti-pinch function. How to avoid similar accidents when traveling in peacetime? 654381On the afternoon of October 25th, the reporter interviewed Nanjing Metro Operation Company on these issues. According to the company, all the lines of Nanjing Metro are equipped with screen doors, which have anti-pinch function and will automatically bounce off when encountering obstacles when closing the door.

The reporter visited Metro Line 2, Line 10 and Line 1 and found that the platform of Nanjing Metro was equipped with screen doors, the underground platform was fully enclosed, and some elevated platforms adopted semi-closed screen doors. After the subway train enters the station, the train door and the screen door will open at the same time. After all passengers enter the carriage, a warning light will flash above the screen door, accompanied by the alarm sound of "Didi", and then the train door and screen door will slowly close. It was not until all the train doors and screen doors were closed that the train started and headed for the next station. Warning slogans such as "Watch the gap", "Watch your hands", "The door light flashes, please don't get on or off" and "The indicator light flashes, please don't get on or off" are posted in conspicuous positions on the doors or screen doors to remind passengers to get on and off.

The screen door is covered with warning signs.

Train doors also have anti-pinch tips.

According to the relevant person in charge of Nanjing Metro Operation Company, except for the screen door of Line 1, all other screen doors of Nanjing Metro were installed at the same time during construction. Screen doors are installed to ensure the safety of passengers, which can not only prevent passengers from accidentally falling into the track area, but also prevent passengers from forcibly entering the track area. At the same time, the underground platform can be fully enclosed, which has the effect of energy saving.

"All screen doors of Nanjing Metro have anti-pinch function. If the passenger is about to be caught by the sliding door on the screen door, please don't panic, the sliding door will automatically pop open. " The person in charge said that the subway train stops for a short time, which sometimes happens. The sliding door on the screen door has begun to close, but there are still passengers rushing to the train desperately. Even if passengers rush into the middle of the closing screen door, they will not be caught, because the screen door has anti-pinch function. In this case, the screen door will automatically bounce off both sides and close again after a few seconds.

At present, Nanjing Metro technology can open and close train doors and screen doors at the same time, both of which have anti-pinch function, that is to say, screen doors will automatically bounce off when encountering obstacles, and will be closed synchronously in a few seconds. On the other hand, train doors encounter obstacles, which will also affect the closing of screen doors. Under normal circumstances, the train will only start running after all train doors and screen doors are safely closed. However, it does not rule out that the screen door cannot be completely closed when it fails. In this case, the train will not run for the time being. Relevant personnel will investigate the cause at the first time to ensure the safety of trains and passengers, arrange trains in an orderly manner, and then urgently arrange professionals to repair the screen doors. If the train doors and screen doors can't be closed, which will affect the safety of the train or passengers, Nanjing Metro generally adopts elevator mode and will resume operation after the fault is eliminated.

"Although both train doors and screen doors have anti-pinch functions, don't rush in and out in the morning and evening rush hours because you are in a hurry." The person in charge said that there are more passengers in the morning and evening rush hours, and accordingly, the frequency of trains is also high, so there is no need to squeeze the bus. If passengers rush in and out, train doors and screen doors will feel obstacles bounce off repeatedly. As long as one door is not completely closed, the train will not start and stop on the platform, which will increase everyone's travel time. If a train is delayed, subsequent trains will also be affected, which may also endanger the safety of subway operation. Therefore, passengers should not get on or off after the subway gate light or screen door indicator light flashes. Passengers who have got on the bus should also take care of their belongings and children at all times to ensure that they are far away from the door, so as not to delay the train because the door cannot be closed normally.
