Abstract

The utility model discloses a detecting device used for detecting gaps of platform screen doors, which is characterized in that the detecting device is a luminous body, which is arranged between platform screen doors and a train and is positioned on the end which is corresponding to the end-piece of a train which is stopped in a station. The detecting device has simple structure, is convenient for drivers positioned in head segment to observe the gap between the platform screen doors and the train, after the system judges that the platform screen doors and the train doors are all complete the closed process and before the train prepares to depart, if the system observe that the light of the detecting device is partly blocked by objects, the driver can know that objects or people stays in the gap, danger exists, and the driver dose not start the vehicle temporarily, after checking that the object which blocks the light is eliminated, then the driver starts the vehicle, thereby, if only the operation of the driver meets the specification, and the absolutely safety of driving can be guaranteed.

Description

Shield door gap sniffer

Technical field

The utility model relates to the safety feature in urban rail traffic platform shield door field, particularly shield door, can prevent and prevent because the generation of the folder people peril that the gap produces between train and the shield door.

Background technology

For improving security, the shield door widespread use following technology: 1, detection system for obstacle: when sliding gate closes hindered lift-cabin door (door closing force is controlled at 150N), door operation mechanism can detect the barrier existence and discharge door closing force, run into the barrier door closing force in the process of closing the door discharges at once, close the door once more after the door pause (adjustable in dead time 0-10 scope second), n the door (number of times scalable) that repeat to close the door still can not be closed, and sliding gate is in free state or opens and report to the police.2, sliding door of screen door switch door state serial-connection system safety return circuit, all sliding gates of shield door are closed and lock-out state is to join by rigid line and signal, guarantee operation security.

Detection system for obstacle makes shield door have pinch resistant functionality, and minimum anti-pinch thickness is 5 millimeters.When shield door clipped to passenger or article in the closed procedure of pass, sliding gate is phase down immediately, lays down clamping force simultaneously, frees the people or the thing that are pressed from both sides, and the back door body weight was newly closed in 1～2 second.Behind the said process triplicate, Men Tiruo still can not close locking, shield door phase down then, and a door body is in free state or full-gear, and the pilot lamp flicker on the shielding header case is reported to the police.This moment, the shield door safety return circuit was obstructed, and train can not normally be dispatched a car under the shield door automatic control mode.

In order to ensure traffic safety, subway design specifications (GB50157-2003) requires each device design and installs to exceed the gauge requirement, and platform screen door has the gauge requirement equally.Vehicle gauge adds that shield door is subjected to may be out of shape behind the blast, shield door after closing and close after car door between must have gap about 180mm, this gap can hold modest person or child, if existing has the people to enter this gap behind shield door and closing of the door, train and signal great casualty accident must occur in the time of can not discovering and continue to start driving, as on July 15th, 07, Shanghai Underground occurred because the fatal accident of gap folder people between shield door and the train.

There is the infra-red detection of employing mode to prevent to press from both sides people's accident abroad, following defective is arranged: 1, need by rail side infra-red detection sensor be installed at sliding gate, must need installing space, strengthen the gap, otherwise survey not thorough or the boundary of transfiniting, if and want whole space is scanned, adopt light curtain cost height; 2, after the installation, the infra-red detection hole is subject to dust or foreign material influence and directly influence driving operation, and reliability is lower.

Summary of the invention

For addressing the above problem, the purpose of this utility model provides a kind of shield door gap sniffer, and it is simple in structure, and reliability is higher.

The purpose of this utility model is achieved in that a kind of shield door gap sniffer, it is characterized in that: described sniffer is a luminophor, and this luminophor is located between shield door and the train and is positioned at an end corresponding with the train rear that stops.

Described sniffer is located at shield door by on the side of track.

Described luminophor is the rectangular luminophor of vertical configuration.

Described rectangular luminophor comprises transparent hose and is series at the interior a plurality of miniature bulbs of transparent hose.

Comprise that also the light with luminophor reflexes to train operator's light reflection unit, be located between shield door and the train and be positioned at an end corresponding with the train head end that stops.

The utility model is simple in structure, convenient driver in train head section observes the space between shield door and the train, before system judges that also preparation was dispatched a car after shield door and train door were all finished bolt down procedure, if observing the light of sniffer is partly blocked by object, the driver has known that promptly object or person rest in the gap, dangerous, wouldn't start vehicle, examine is restarted vehicle after eliminating the object of blocking light, therefore as long as driver's working specification compliant just can guarantee that driving is perfectly safe.

Embodiment

As shown in Figure 1, the utility model is a kind of shield door gap sniffer, described sniffer is a luminophor 4, this luminophor 4 is located between shield door 1 and the train 2 and is positioned at an end corresponding with the train rear 21 of stopping, preferably, luminophor 4 is located on the shield door end door 11 with the train rear 21 corresponding ends that stop.For making things convenient for the driver to observe, be provided with a light reflection unit 3 (as reversing face) or the driver observation of directly getting off in the train head end side the place ahead of stopping, so that observe the light of luminophor 4.If shield door with vehicle interlock, need the driver operation shield door PSL (console panel on the spot) that gets off, adopt this moment driver's Direct observation gap whether to have object to have the mode the best of driving again; If shield door and vehicle interlock, moving normal driver does not need to control shield door PSL, can observe by light reflection unit 3 (as reversing face) is set.

As shown in Figure 2, described sniffer is fixed in shield door end door 11 by on the side of track 5, and goes into power supply and switch at shield door end door 11 edge joints.In the present embodiment, sniffer is the rectangular luminophor 4 of vertical configuration, comprises transparent hose 42 and is series at a plurality of miniature bulbs 41 in the transparent hose 42.
