Description

Sliding emergency door open/close detection system {Sliding emergency door open/close detection system}

The present invention relates to a system for detecting opening and closing of a sliding emergency door, and relates to a system for detecting opening and closing of a sliding emergency door capable of detecting an open and closed state of a sliding emergency door for opening and closing an emergency exit of a screen door.

In general, a screen door refers to a safety device that can be opened and closed in conjunction with the entrance and exit doors of a vehicle (e.g., subway, train, train) by installing a fixed wall and an entrance door on a platform of a train, and a platform screen door (Platform Screen Door: PSD). That is, by installing a fixed wall and a movable door (or PSD door) isolated from the track on the platform of the train, it means a platform safety support device or such system that opens and closes in conjunction with the door of the vehicle.

When the train is completely stopped at the platform platform, these screen doors open together with the train doors to secure passenger safety, reduce noise, dust, and strong winds caused by the train, and prevent passengers from intentionally or accidentally falling onto the tracks. do

In addition, there are three types of screen doors: a fully enclosed type that completely separates tracks and platforms with a fixed wall, a semi-enclosed type that places an opening or gallery on a fixed wall and a movable door, and a handrail type that installs a movable door according to the position of the vehicle door. It can be divided into , and can be applied to subway, light rail, high-speed train, monorail, etc.

Screen doors have the following effects: 1) prevention of passenger fall and contact with trains, 2) reduction of station staff, 3) unmanned operation of trains, 4) improvement of passenger mobility and high-speed operation, 5) prevention of strong wind and soundproofing and dustproofing of vehicles. Maintaining the comfort of the platform, 6) anti-smoking effect in the event of a train fire, and 7) reduction of the station ventilation tower and machine room, etc. It is pointed out as a disadvantage that there is a concern that the speed of getting on and off is delayed.

In addition, the screen door is normally closed and an emergency door (or emergency exit panel) is installed as a safety zone that can be opened in an emergency situation such as a malfunction of a movable door. This emergency door is a device provided so that passengers can escape to the platform by forcibly opening it in an emergency situation, and is also a space into which the movable door enters when the movable door is opened.

It is mandatory to install such an emergency door on a screen door in consideration of the safety of passengers in an emergency situation.

As a prior art of a screen door equipped with an emergency door, Korean Patent Registration No. 10-2226661 (title of invention: emergency door for a platform safety door that opens and closes in a sliding way) is a sliding safety door that is transported from the inside of the upper frame in an emergency situation The emergency exit of the screen door is opened and closed in a sliding manner guided by a rotation guide fixed to the frame, so that the emergency exit can be opened even if there is an obstacle on the outside of the sliding safety door. It has the effect of keeping them safe.

When such a sliding emergency door is applied to a platform, in an emergency situation, the driver of the vehicle or a person in the station needs to check the opening and closing state of the emergency exit according to the sliding of the sliding safety door, and whether the passenger escapes according to the opening and closing state of the emergency exit You can judge and request emergency rescue from outside.

In this way, the sensor for detecting the open/closed state of the emergency exit is usually installed in the screen door. Conventionally, a long frame-shaped steel detection bar (or detection magnet) is embedded in the sliding safety door, and the sensor is installed in the sliding safety door. A system capable of detecting an open/closed state of a sliding safety door through a distance to the steel detection bar according to movement has been developed.

However, since such an opening/closing detection system requires a long frame-shaped steel detection bar to be embedded in the sliding safety door, the sliding safety door has a problem in that the volume of the device inevitably increases according to the long frame-shaped steel detection bar.

Magnetic binding can be made, and unlike the contact of the second sensor unit 150 is in an ON state, the control unit 195 controls the power to be in an off state, and the magnetic force with the first magnet part 110 Bindings can be broken.

In one embodiment, when the second sensor unit 150 is forcibly powered off by the second panic bar 170b, the fourth sensor unit 182 powers through forced startup of a built-in battery. This forcibly turned on state can maintain the open state of the second emergency exit 24 through magnetic coupling with the first magnet part 110 .

The power supply unit 190 is electrically connected to batteries embedded in the first, second, third, and fourth sensor units 140, 150, 181, and 182, and the operation is controlled by the control unit 195 to Power is supplied to the batteries of the first, second, third, and fourth sensor units 140, 150, 181, and 182 so that the batteries are charged.

The control unit 195 controls the operation of the power supply unit 190 so that when the sliding emergency door 100 closes both the first and second emergency exits 23 and 24, the first sensor unit 140 and the second emergency exit Waste of electric energy can be prevented by supplying power to the second sensor unit 150 and at the same time cutting off power supply to the third sensor unit 181 and the fourth sensor unit 182, which do not require operations.

In one embodiment, the control unit 195 controls the operation of the power supply unit 190 to open at least one of the first emergency exit 23 and the second emergency exit 24 opened by the sliding emergency door 100 in an emergency situation. At least one of the first emergency exit 23 and the second emergency exit 24 is maintained in an open state by supplying power to at least one of the third sensor unit 181 and the fourth sensor unit 182 adjacent to one.

In one embodiment, the control unit 195 needs to detect the situation of the platform 1 or the track in order to control the operation of the power supply unit 190, and for this purpose, the sliding emergency door opening and closing detection system has an emergency situation. A detection sensor 197 may be further provided.

The emergency detection sensor 197 is installed on the platform 1 and the track to detect the occurrence of an emergency on the platform 1 or the track, and when an emergency is detected, an emergency detection signal is generated to control the control unit ( 195), the control unit 195 can control the operation of the power supply unit 190 according to normal times and emergency situations.

The emergency situation detection sensor 197 may be implemented as an infrared sensor and a power failure detection sensor for detecting the occurrence of an emergency situation (eg, fire, power outage, etc.). However, the above-described sensor is only an example and is preferably implemented as a sensor capable of detecting an emergency situation that may occur in the platform 1 and the track.
