Description
Technical field
The utility model is related to track shield door (safety door) safe detection technology field, more particularly to a kind of track shielding
Door scan-type beam detection device and system.
Background technology
Track (subway or railway) door apparatus can prevent from passenger from falling track causing danger, and reduction artificially causes
Stop delay and driving accident.To ensure safe train operation, also need to retain certain door between train and shield door
Vehicle insulating space.When have passenger do not take into account safety signal prompt, get on the bus not at again without the route of retreat when, human body may be sandwiched in subway
At door vehicle gap location or door vehicle channel isolation in high ferro subway, it thus may lead to the generation of casualty accident, jeopardize simultaneously
Traffic safety.
In order to ensure passenger's personal safety and train normal operation, in recent years metro operation department make great efforts to explore effectively and
Reliable shield door and train gap anti-pinch people's safety measure, including：(1) the light bar security display of platform tail end.It is by hanging
A string of luminous tubes composition for hanging over the tailstock, is installed on the outside of the column of shield door vehicle tail end.Driver needs before launch train
It passes through interstitial area to be looked to Che Wei from headstock position, if complete light bar can be clearly seen, is considered as between shield door and train
There is no shelter.But the object for distal end and at ground or children's delay, inevitably carelessness and judgement are lost for artificial observation
Accidentally.Platform may can't see tail-light band again when being curved section.(2) short distance correlation infrared ray light curtain detector.It is red
The side of outer line detector is the equidistant infrared light emission pipe for erectting arrangement, and the other side is that identical quantity corresponds to the infrared of arrangement
Photoelectric receiving tube, transmitting column and reception column are established among shield door and train door crack.When being blocked if any barrier, because
Column is received not receive infrared signal and send out alarm.Due to infrared light emission pipe send out light beam the angle of divergence and hot spot compared with
Greatly, thus in transmission process decay larger and cause transmission range close, and be susceptible to disorderly instead in narrow gap interface is transmitted
It penetrates phenomenon and fails to report police.(3) long range correlation laser detector.It is at the beginning of entire elongated isolation strip zone of protection
Laser transmitter is set, the laser beam launched is emitted directly toward at terminal receiver.The pulse received is swashed by receiver
Optical signal is converted into corresponding electric signal, when laser beam is blocked by barrier, then sends out alarm signal to control host.This swashs
Optical detector is primarily adapted for the straightway of long range, and whole installation and wiring are simple and direct, reliable operation and easy maintenance.In curve
Section then may increase cost because increasing zone devices.
But the sliding door outer edge of subway shield door has been in specified devices safety (towards the edge of track) at present
In limit, if the area of isolation between the sliding door outer edge and train of shield door detects, above-mentioned subway correlation master
The detecting head of dynamic pyroscan and subway correlation laser detector must be reached to train directions outside sliding door again
Position other than edge.Therefore, forced carry out of subway department allows beyond specified devices safety clearance and without departing from vehicle at present
Safety clearance installs detection device.Equipment safety limit as defined in this long-term intrusion is installed, and due to long-term vibration
Detection device may further cross the way of vehicle safety limit in operation, increase the danger of train and detection device scraping collision
Property, long-term hidden danger is constituted to traffic safety.Meanwhile detection device is to prevent intrusion vehicle gauge, warning light beam is too inclined when installation
In close to sliding door outer edge, it will increase when isolated area is wider and fail to report alert possibility.CN201310409622.5 is disclosed
Beam emissions device and beam reception device are respectively provided with by a kind of telescopic beam detection system in high ferro and subway system
Beam emissions device and beam reception device is set to enter isolation during train is stopped in safety zone, and by driving mechanism
Area, realization probe beam can be displaced outwardly and enter in isolated area and be detected, and safety zone is retracted into after detection,
To be protected while having taken into account train and passenger's personal safety.And in order to adapt to the human body of different regions and age, it can
It eliminates detection blind area and improves the reliability of detection, generally require above to lay several beams at various height, cause device knot
Structure complicates, and operation and maintenance cost improves, and also is difficult in wider area of isolation to avoid the spy to children's human body completely
Survey blind area, however it remains some potential safety problems.
