Description
Technical field
The utility model relates to railway security Detection Techniques field, relates in particular to a kind of telescopic laser detection system.
Background technology
Shield door (or safety door) systemic effect that the platform of high-speed railway, inter-city passenger rail is provided with safety door (or shield door) system and subway roughly the same, can prevent from falling when passenger from waiting track, and train at a high speed by time the air negative pressure danger that forms, reducing people is stop delay and the driving accident causing.But, for guaranteeing the safe operation of train, between train and safety door (or shield door), must retain the area of isolation of certain width.In general, this area of isolation comprises safety clearance inner region and safety clearance exterior domain two parts, and safety clearance inner region is that safety clearance region is arrived in safety door sideline, allows to arrange safety device, safety clearance exterior domain is that safety clearance arrives region, train sideline, forbids installing any equipment.
When a few passengers, ignore safety signal prompting, get on the bus while not becoming not return in time again in safety door, human body or the object carrying just may be trapped in area of isolation place, thereby may cause the generation of casualty accident, jeopardize traffic safety simultaneously.For this reason, the safety door of high ferro, subway and subway (or shield door) system all needs area of isolation to take anti-pinch people safeguard measure.
Because subway train travelling speed is low, its area of isolation is very narrow, and safety clearance exterior domain, much smaller than normal human's width, therefore arranges safety device in safety clearance, and the anti-pinch people that can simultaneously realize safety clearance exterior domain detects or protection.Anti-pinch people's safety practice that metro operation department takes in the area of isolation of shield door (or safety door) and train in recent years, mainly comprise: (1) arranges lamp band security display at subway platform tail end, driver is before launch train, need to the tailstock, observe from headstock position through interstitial area, if be clear that whole lamp bands, just think and there is no shelter between shield door and car door.But artificial unavoidable carelessness and the error in judgement of observing, may can't see again tail-light band when platform is segment of curve; (2) at the sliding gate edge of subway shield door (or safety door), install safety screen additional, can reduce gap between train door and shield door, reduced the possibility that passenger enters this gap.But, often can only stop passenger initiatively to enter interstitial area, but can not prevent that passenger is passive by clamp-oning this gap in car, now danger is larger for launch train; (3) subway correlation active infrared line detector.One side of active infrared line detector is the infrared transmitting tube of equidistantly installing, and opposite side is the same infrared electro receiving tube of arranging of equal number, and detector post is established in the safety clearance in the middle of shield door and train door crack.When having barrier to block, infrared receiving tube sends warning because of the infrared signal that can not receive opposite and send.The angle of divergence and the hot spot that due to infrared transmitting tube, send light beam are larger, during transmission power density decay large, when the transmission of narrow gap, easily there is irregular reference phenomenon and fail to report police, thereby be mainly used in short-range single-unit car door protection.(4) subway correlation laser detector.At the whole elongated top with zone of protection, laser transmitter is set, by direct the laser beam fabulous directivity of launching directive terminal receiver place.By receiver, convert the modulated light signal receiving to corresponding electric signal, when light beam is interdicted, to main control system, send alerting signal, thus realize to laser beam the whole process monitoring of process.The straight-line segment that it is mainly suitable for long distance, may strengthen equipment cost at segment of curve.
But, in high-speed railway, inter-city passenger rail, because travelling speed significantly improves, safety clearance is obviously offset to direction in platform, cause the outer area of isolation of safety clearance far to exceed human body width (example 690mm), the easy hazardous location of being detained and pressed from both sides of passenger is obviously strengthened.Because the platform plane top of the outer area of isolation of safety clearance does not allow to install additional any equipment and pick-up unit, therefore high speed traveling, wide region be detained, again without safety detection and safeguard procedures, these several factors are also deposited and are made passenger's personal safety and traffic safety be subject to even more serious threat.But, there is no at present any effective measures and solve the safety clearance security protection problem of area of isolation outward.
Therefore,, for above deficiency, the utility model provides a kind of telescopic laser detection system.
