This technical scheme need not through additional processing software, and only the hardware by the system of arranging constitutes the setting, can directly realize the volume of traffic detection accuracy when it goes to improve vehicle standdle carrier way, and its component is very simple, and it is accurate, high -efficient to detect.
Description
Technical field
This utility model application relates to road online dynamic operation data pick-up harvester, particularly relates to be fixedly installed on the arrangement of the contact pick-up harvester of carriageway surfacing.
Background technology
Today that highway communication system is fast-developing, its planning, build, system perfecting and coordinated management, must be based on the classification to actual measurement traffic data, process, analysis result, these measured datas include that vehicle dynamic runs real-time traffic amount data, great majority are the contact-type detection ground induction coils utilizing and being embedded in road surface central authorities, vehicle changes by i.e. causing ground induction coil inductance value, and make oscillating circuit output frequency correspondence change, analyzed by control of intelligent terminal, process, comprehensive according to obtaining speed again, lane occupancy ratio and vehicle and the accounting etc. of all kinds of vehicle.
Current ground induction coil is motor vehicles lane center arrangement, parallel each track ground induction coil is arranged in the same traversing section in road surface, it is 2:3～3.75 that the ground induction coil width in each motor vehicles track accounts for the accounting of lane width, as a example by the two-shipper motor-car track of Fig. 1, motor vehicles lane width standard is 3～3.75m, conventional absolute distance between the ground induction coil in two adjacent motor vehicles tracks is 1m, in motor vehicles current international practice standard, minicar overall width is 1.6m, the overall width of other class vehicle is more than 1.6m, 1.8～2.5m.When vehicle line ball is across lanes, two track ground induction coils of inter-bank can produce sensing change simultaneously, all produces a vehicle flow value at two lane detection harvesters, causes collection value higher than actual value.Existing Technical Solving is to use software analysis removal method, the time compared by model, arrive, left is to reject for condition etc. to have more quantity of information simultaneously, but vehicle huge number, vehicle driving mode are various, it is difficult to be rejected by one or one group of mathematical model or conditional judgment, and with reference to, judge that data volume is huge, cause detecting poor efficiency, also result in accuracy of detection and decline.
Summary of the invention
The goal of the invention of this utility model application is to overcome vehicle across lanes, can two adjacent motor vehicles track ground induction coils of inter-bank produce simultaneously sensing pick-up signal, cause detecting value increase, impact detection this technical problem of value accuracy, it is provided that a kind of vehicle the most only produces pick-up signal across lanes, the quasi-value of volume of traffic height of raising collection capacity accuracy dynamically detects multilane ground induction coil arrangement.The quasi-value of volume of traffic height that this utility model patent application provides dynamically detects multilane ground induction coil arrangement technical scheme, its main technical content is: a kind of quasi-value of volume of traffic height dynamically detects multilane ground induction coil arrangement, including the ground induction coil portion being individually fixed in parallel same horizontal road surface, each motor vehicles track section, corresponding electric pick-up signal is produced when vehicle runs through for sensing, wherein a motor vehicles track is that standard disposes track, its ground induction coil portion fixed in position is in these standard lane central authorities, the ground induction coil portion in the motor vehicles track being adjacent, its road occupying width is less than the ground induction coil portion road occupying width disposing track with described standard, and described two ground induction coil absolute distances are 1.2～1.6m.Described absolute distance is the distance intersegmental closest to coil of the ground induction coil in described two motor vehicles track.
The quasi-value of volume of traffic height disclosed in this utility model application dynamically detects multilane ground induction coil arrangement technical scheme, without by additional treatments software, only constituted setting by the hardware of the system of layout, raising vehicle Traffic volume detecting accuracy when lanes can be directly realized by, its composition is extremely simple, and detection is accurately, efficiently.

Detailed description of the invention
The quasi-value of volume of traffic height that this utility model application provides dynamically detects multilane ground induction coil arrangement, the ground induction coil portion being fixedly installed including same horizontal road surface, each parallel machine motor-car track section, runs through for sensing the vehicle in each motor vehicles track.When vehicle is often by ground induction coil portion, i.e. can produce corresponding inductance value, then cause the rate-adaptive pacemaker of its oscillating circuit to change, including amplitude and frequency values, Intelligent treatment terminal gathers the pick-up signal in each motor vehicles track, measures the traffic data in each motor vehicles track.
Embodiment explanation with Fig. 2, one motor vehicles track D2 is that standard disposes track, its ground induction coil portion L2 mounting structure routinely, it is fixedly installed on the central authorities of motor vehicles track D2, the normal width in motor vehicles track is 3.00～3.75m, ground induction coil portion L2 is positioned at this motor vehicles track D2 central authorities, and its both sides coil segment l21, l22 ratio away from lane boundary d21, the distance S2 sum of d22 and lane width is preferably 1:3～3.75；Dispose the motor vehicles track D1 adjacent for motor vehicles track D2 in track with standard, its ground induction coil portion L1 road occupying width disposes the road occupying width of the ground induction coil portion L2 in track less than standard, and it is 1.2～1.6m with the absolute distance of described ground induction coil portion L2.Under the conditions of above-mentioned, dispose the motor vehicles track D1 ground induction coil L1 road occupying width that track is adjacent with standard, be designed as 1m and be more suitable for.Described absolute distance be ground induction coil portion L1, the L2 in two motor vehicles track closest to the lateral separation between coil segment l12 and l21, be also lane boundary d21 in two motor vehicles track distance S1 away from ground induction coil portion L1 coil segment l12 and away from ground induction coil portion L2 coil segment l21 distance S2 sum.
Sensing operation principle during vehicle travels is: vehicle is when its motor vehicles lanes, and its sensing detection is as good as with existing ground induction coil detection device detection mode；When the motor vehicles fraction on the D2 of motor vehicles track is to adjacent motor vehicles track D1 inter-bank, still sensed it by the ground induction coil portion L2 in this track and pass through state, if this motorcar body overwhelming majority inter-bank is to adjacent motor vehicles track D1, the most only sensed it by the ground induction coil portion L1 of adjacent motor vehicles track D1 and pass through state, other ground induction coil portion, motor vehicles track will not be caused to sense work；In like manner, motor vehicles inter-bank for travelling on the D1 of motor vehicles track is detected by sensing, thus when overcoming the arrangement of existing track induction installation to meet vehicle inter-bank, two inter-bank tracks all can produce sensing pick-up signal, add detection value, the technical problem of impact detection value accuracy, use simple ground induction coil arrangement, achieve the technical purpose of the accuracy improving sensing detection, and without complicated software processes, there is the efficient technological merit of detection.
