When a train enters or departs from the platform, the door is opened and closed by interlocking with the door of the train. When the train stops after entering the platform, the door is automatically opened at the same time as the entrance door and the passenger gets off the train And the moving door is automatically closed at the same time as the entrance door, before the passenger is aboard the railway car and the departure is completed.

Therefore, in addition to preventing the risk of a safety accident such as falling of a passenger from a platform to a track, and securing safety, strong winds generated during operation of the electric railway block the entry of train wind and dust into the platform, But also increases the cooling and heating effect.

On the other hand, in the screen door system, a plurality of emergency doors for moving a passenger on an electric train from a train to a platform or from a track to a platform in an emergency such as accident or sudden shutdown of a train, As shown in Fig.

Since the emergency door is provided so as to be openable and closable in the fixed frame so as to serve as a passageway for passengers moving from the railway to the platform, the emergency door is provided with a panic bar for manually opening and closing the emergency door, As the passengers moving from the track to the platform move the panic bar by pushing or pivoting, the emergency door is opened so that the passengers move from the rail side to the platform through the opened emergency door, and when the passengers are moved or the emergency door is normally closed have.

Here, the opening and closing state of the emergency door in the related art is determined by using the proximity sensor or the limit switch to open and close the emergency door.

That is, a sensor detection plate is mounted on the upper side of the emergency door of the screen door system, and a proximity sensor is installed on the upper side fixing frame so that the proximity sensor senses the sensor detection plate to determine opening and closing of the emergency door, , A limit switch is installed on the upper side fixed frame of the screen door system to detect whether the emergency door touches the limit switch to determine whether the emergency door is open or closed.

However, the method of judging opening and closing of the emergency door of the screen door system is a problem in that the opening and closing states of the emergency door can not be accurately confirmed due to the position detecting method using the proximity sensor and the touch detecting method using the limit switch.

Therefore, even when the emergency door is not locked or is not completely locked, the emergency door is recognized as a locked state when the emergency door is in the locking position, so that the emergency door is opened due to the heat wind generated when the electric vehicle enters. There has been a problem that a passenger of the platform is injured by the emergency door or a passenger is dropped from the platform to the railway when the emergency door is opened.
