In general, safety clearance is provided with further in this area of isolation, area of isolation and the outer area of isolation two parts of safety clearance in safety clearance are divided into again accordingly in area of isolation, in safety clearance, area of isolation is that safety door sideline is to safety clearance region, allow to arrange safety device, the outer area of isolation of safety clearance is that safety clearance is arrived at a station platform edge area, forbids installing any equipment.
When a few passengers ignores safety signal prompting, get on the bus into when not returning in safety door in time again, human body or the object carried will be trapped in this area of isolation place, namely may cause the generation of casualty accident, jeopardize traffic safety simultaneously after launch train.For this reason, safety door (or shield door) device of high ferro, subway all need be taked to detect safeguard procedures reliably at this area of isolation.
There is similar situation equally in subway.Because subway train travelling speed is low, without escape truck effect, thus this region is very narrow again for its area of isolation, the outer area of isolation of safety clearance thus in subway is very narrow, much smaller than normal human's width, therefore in existing safety clearance, area of isolation allows the safety device arranged, and the anti-pinch people that simultaneously can take into account the outer area of isolation of safety clearance detects or protection.Such as area of isolation in the existing safety clearance of subway platform, the sliding gate of shield door (or safety door) installs safety screen additional, and the method such as correlation active infrared line detector and correlation laser detector that crack passage is installed all may take into account the protection of the outer area of isolation (being such as less than 50mm) of very narrow safety clearance.
But, in high-speed railway, inter-city passenger rail, because travelling speed significantly improves, safety clearance obviously offsets to direction in platform, the outer area of isolation of safety clearance is caused obviously to be widened, and far exceed human body width (such as 640mm), add that in the gauge that its passenger's escape truck function causes, area of isolation is widened, make passenger be very easy to be trapped in dangerous area of isolation.Because the platform of the outer area of isolation of safety clearance does not above the ground allow to install any equipment and pick-up unit additional, so cause the outer area of isolation of high speed traveling, wide safety clearance, several the factors such as detection and safeguard procedures cannot be installed and deposit, make passenger's person and traffic safety be subject to even more serious threat.
And, allowing and be convenient in the safety precaution of general search coverage of increase checking device, normally adopt generating laser, infraluminescence pipe and microwave emitter etc. and be equipped with corresponding receiver to form correlation wire harness intrusion detector, and adopting multi-thread bundle and grid type to rearrange plane intrusion detector.In order to ensure wide covering and reduce undetected survey as far as possible, need the quantity increasing considerably wire harness equipment, significantly can strengthen equipment cost thus and obviously increase technical complexity, thus also seriously limit their promotion and application.
