Description
Technical field
The present application relates to the online dynamic operation data pick-up harvester of road, more particularly to it is fixedly installed on track
The arrangement of the contact pick-up harvester on road surface.
Background technology
Highway communication system fast-developing today, it is planned, built, system perfecting and coordinated management, must be based on pair
The classification, processing, analysis result of traffic data are surveyed, these measured datas include vehicle dynamic operation real-time traffic amount number
According to most of is that vehicle by feeling with triggering using contact-type detection --- the ground induction coil for being embedded in road surface center
Winding inductance quantity changes, and makes the corresponding change of oscillating circuit output frequency, is analyzed, handled by control of intelligent terminal, then comprehensive ratio
According to acquisition speed, lane occupancy ratio and accounting of vehicle and all kinds of vehicles etc..
Current ground induction coil is motor vehicle lane center arrangement, and parallel each track ground induction coil is arranged in road
The same traversing section in face, the accounting that the ground induction coil width in each motor vehicle track accounts for lane width are 2：3~3.75, with the double of Fig. 1
Exemplified by motor vehicle track, motor vehicle lane width standard is 3~3.75m, between the ground induction coil in two adjacent motor vehicle tracks
Conventional absolute distance is 1m, and in motor vehicle current international practice standard, minicar overall width is 1.6m, and the overall width of other class vehicles is more than
1.6m, in 1.8~2.5m.When vehicle line ball is across lanes, two track ground induction coils of inter-bank can produce to sense simultaneously to be changed,
A vehicle flow value is all produced in two lane detection harvesters, causes collection value to be higher than actual value.Existing technology solves
Method is to use software analysis removal method, and the time compared by model, reach, left is to have more letter simultaneously for rejectings such as conditions
Breath amount, but vehicle huge number, vehicle driving mode are various, it is difficult to picked by one or one group of mathematical modeling or condition judgment
Remove, and reference, judge that data volume is huge, cause to detect poorly efficientization, also result in accuracy of detection decline.
The content of the invention
The goal of the invention of the present patent application is to overcome vehicle across lanes, can be in two adjacent motor vehicle tracks of inter-bank
Ground induction coil produces sensing pick-up signal, causes to detect value increase, influences detection value accuracy this technical problem simultaneously,
A kind of vehicle is provided also only to produce a pick-up signal across lanes, improve the high accurate value of the volume of traffic of collection capacity accuracy dynamically
Detect multilane ground induction coil arrangement system.Feel the high quasi- value dynamic detection multilane of the volume of traffic that present patent application provides
Coil arranges system technical scheme, and its main technical content is：A kind of high quasi- value dynamic detection ground induction coil of multilane volume of traffic
Arrangement, including the ground induction coil portion of the same horizontal road surface section in parallel each motor vehicle track is individually fixed in, for sensing
Vehicle operation produces corresponding electric pick-up signal when passing through, wherein a motor vehicle track, which is standard, disposes track, its ground sense line
Circle portion fixed in position is less than in standard lane center, the ground induction coil portion in motor vehicle track adjacent thereto, its road occupying width
The ground induction coil portion road occupying width in track is disposed with the standard, and the two ground induction coils absolute distance is 1.2~1.6m.Institute
The absolute distance stated is the distance intersegmental closest to coil of the ground induction coil in the two motor vehicles track.
The high quasi- value dynamic detection multilane ground induction coil arrangement system technical scheme of the volume of traffic disclosed in the present patent application, nothing
Setting only need to be formed by the hardware of arrangement system by additional treatments software, you can be directly realized by and improve vehicle across lanes
When the Traffic volume detecting degree of accuracy, its composition is extremely simple, and detection is accurate, efficiently.

Embodiment
The high quasi- value dynamic detection multilane ground induction coil arrangement system of the volume of traffic that the present patent application provides, including it is each parallel
The ground induction coil portion of the same horizontal road surface section fixed setting in motor vehicle track, the vehicle for sensing each motor vehicle track are run
Pass through.Vehicle often by ground induction coil portion when, i.e., can produce corresponding inductance value, then trigger the frequency of its oscillating circuit defeated
Go out change, including amplitude and frequency values, Intelligent treatment terminal gathers the pick-up signal in each motor vehicle track, measures each motor vehicle car
The traffic data in road.
Illustrated with Fig. 2 embodiment, one motor vehicle track D2 is that standard disposes track, and its ground induction coil portion L2 is routinely
Mounting structure, is fixedly installed on motor vehicle track D2 center, and the normal width in motor vehicle track is 3.00~3.75m, ground sense
Coil portion L2 be located at this motor vehicle track D2 center, its both sides distance S2 of coil segment l21, l22 away from lane boundary d21, d22 it
It is preferably 1 with the ratio with lane width：3~3.75；The motor vehicle track adjacent with the motor vehicle track D2 in standard placement track
D1, its ground induction coil portion L1 road occupyings width are less than the ground induction coil portion L2 in standard placement track road occupying width, and it is with described
The absolute distance for feeling coil portion L2 is 1.2~1.6m.According under above-mentioned condition, the motor vehicle track adjacent with standard placement track
D1 ground induction coil L1 road occupying width, is designed as 1m and is more suitable for.Described absolute distance is the ground induction coil in two motor vehicles track
Portion L1, L2 closest to the lateral separation between coil segment l12 and l21, and two motor vehicles track lane boundary d21 away from ground sense
Coil portion L1 coil segments l12 distance S1 and away from ground induction coil portion L2 coil segment l21 distance S2 sums.
Vehicle traveling in sensing operation principle be：Vehicle when its motor vehicle lanes, its sense detection with it is existing
Ground induction coil detection means detection mode is no different；When the motor vehicle fraction on the D2 of motor vehicle track is to adjacent motor vehicle track D1
During inter-bank, it is still sensed by state by the ground induction coil portion L2 in this track, if the motorcar body overwhelming majority inter-bank is to phase
During adjacent motor vehicle track D1, then it is only sensed by state by adjacent motor vehicle track D1 ground induction coil portion L1, will not caused
Other motor vehicle track ground induction coil portions sense work；Similarly, pass through for the motor vehicle inter-bank travelled on the D1 of motor vehicle track
Sensing detection, so as to overcome the arrangement of existing track induction installation meet vehicle inter-bank when, can be produced on two inter-bank tracks
Raw sensing pick-up signal, the technical problem for adding detection value, influenceing detection value accuracy, using simple ground induction coil
Arrangement, the technical purpose for the accuracy for improving sensing detection is realized, without the software processing of complexity, have detection high
The technological merit of effect.
