For the safe linking of head car 26-1 that keep straight under realizing bridge trailer 27-1 and bridge turn left, this example adopts and is closely connected pattern: even the stop-for-waiting on bridge in advance such as left-hand bend vehicle 26-1, head car 26-1 by forbidden at assigned address; After the trailer 27-1 that keeps straight under bridge is by lower bridge car management and control door 28-1, this opens and the left-hand bend fleet immediately clearance bridge waited at once.
Figure 13 is exactly the situation that above-mentioned two train flows are about to realize closely being connected a moment; Trailer 27-2 now keep straight under bridge just by lower bridge car management and control door 28-2, and this door is opened immediately, and the left turning vehicle 26-2 etc. that bridge is waited for starts to walk at once, after the trailer 27-2 that keeps straight under bridge.
Reaching above-mentioned effect also needs craspedodrome trailer to judge trap setting to assist, and craspedodrome trailer judgment means can apply the prior aries such as the information capture analytical equipment of infrared transmitting device.
Embodiment 7: the loose wagon flow be connected is connected control system
The scheme that a upper embodiment provides is applicable to use when traffic pressure is larger, such as morning and evening peak period, and this pattern has by the high advantage of efficiency, but needs the parking on bridge of left-hand bend vehicle to wait for; Being easy to like this knocks into the back because the control of artificial spacing is improper scratches accident.
For overcoming above defect, Figure 14 provides a kind of control program of loose linking; Namely the moment of bridge on left-hand rotation elbow car 26-3 is postponed; These needs are commanded accurately left-hand rotation elbow car and control.
After above-mentioned adjustment, when keeping straight on trailer 27-3 under bridge when lower bridge car management and control door 28-3, door leaf are opened, left-hand rotation elbow car 26-3 does not also arrive bridge handle lower end; So just there is not the possibility that left-hand bend vehicle is waited on bridge, better can control spacing to ensure safety.
Loose linking pattern is kept straight between trailer 27-3 under making left-hand rotation elbow car 26-3 and bridge larger personal distance, and this interval is unsuitable excessive, otherwise can cause unnecessary path resource waste; On wagon control, when following bridge car management and control door 28-3 opens, left-hand rotation elbow car 26-3 just reaches bridge top and is advisable.
Overpass bridge especially interchange viaduct is very large for alleviation traffic congestion effect, but most of overpass bridge especially interchange viaduct all build megalopolis in, a lot of crossings of center, city or old town do not possess the condition of building big-and-middle-sized overpass bridge yet; And in small and medium-sized cities even metropolis, grade crossing still exists in a large number, and the bicycle road twocouese overpass bridge of therefore lightweight, miniaturization has very large application prospect.
