(1) ground induction coil detection
The installation process of ground induction coil need to cut road surface, and road pavement is destroyed serious, affects Road Service Life；Each coil
Being both needed to threading, speed of application is slow, takies the road surface time long；Additionally special road section such as bridge, tunnel etc. is difficult to install.
Heavy vehicle causes surface deformation or not by, pavement maintenance, high latitude situations such as phase and low latitudes summer that thaw
The smooth Detection results that can affect, increases maintenance workload；Feeder line breakdown impact uses；Road surface canalization again needs again to cut road
Face is installed.
It is long that maintenance process takies the road surface time；As single coil damages, it is impossible to cutting lead groove in situ, cause road surface
Damage, affects the attractive in appearance and life-span；Average maintenance times is many.
Ground induction coil detection is poor with the compatibility of traffic information acquisition system based on other technology.
(2) Video Detection
Video Detection generally needs independent vertical rod, threading；It is long that construction takies the road surface time.
Illuminance is required higher by Video Detection, wind, rain, snow, mist, etc. weather and backlight can affect accuracy of detection.
It is long that maintenance process takies the road surface time, needs work high above the ground.
In addition to Ethernet interface, Video Detection can meet the demand of remaining system, is used for existing section.
(3) microwave detection
Microwave detection needs vertical rod, threading, if Detection results to be improved, needs set up gantry on section or be installed on
On overpass.
Microwave detection is when speed is less than 20 kilometers/hour, and accuracy of detection is the highest.
I&M is made to become the most complicated since it is desired that forward is installed on portal frame or L-type crossbeam.
In addition to Ethernet interface, microwave detection can meet the demand of remaining system, is used for existing section.
Existing section vehicle detection mode, installing, use, safeguard and have in terms of compatibility various deficiency, and,
Existing detecting system is in addition to providing data on flows, it is impossible to provide the parameters such as Vehicle Speed, occupation rate, time headway.
Utility model content
The utility model proposes a kind of wireless vehicle detecting system, use the existence of the detector detection vehicle on embedment road surface
With pass through, by wireless network, detection data are sent to upper receiver in real time.
The technical solution of the utility model is achieved in that
A kind of wireless vehicle detecting system, including: detector, timer and wireless base station apparatus, specific bit in track
Putting one hole of brill, inserted by detector in hole so that it is consistent with traffic direction, seal hole with fluid sealant, detection vehicle exists
With the time of passing through；
The built-in magnetoresistive transducer of described detector, senses owing to vehicle disturbs the GEOMAGNETIC CHANGE caused, and GEOMAGNETIC CHANGE amount is big
Exporting high level when predetermined threshold value, GEOMAGNETIC CHANGE amount is less than output low level during predetermined threshold value；
The outfan of described magnetoresistive transducer is connected to timer, and high level lasting time carries out timing, described high electricity
The flat persistent period is that vehicle passes through the time；
Described wireless base station apparatus is connected to described timer, is sent to upper by vehicle by wireless network by the time
Receiver.
Alternatively, described timer includes constant-current source and capacitor, and when timer receives high level, constant-current source is to electric capacity
Device charges, and the magnitude of voltage correspondence vehicle at capacitor two ends passes through the time.
Alternatively, described timer includes enumerator, and when timer receives high level, enumerator starts counting up, counting
Value is multiplied by the counting cycle and passes through the time equal to vehicle.
The beneficial effects of the utility model are:
(1) need not lay pipeline, installation is quickly and easily, little on road surface impact, does not affect roadbed, road pavement
Holding time is short, safeguards simple and convenient；
(2) accuracy of detection is high, reliable and stable, is not affected by natural environment and weather (rain, snow, mist, night etc.).

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
The utility model proposes a kind of wireless vehicle detecting system, including: detector, timer and wireless transmission dress
Put.
As shown in Figures 1 to 4, specify position to bore a hole in track, detector 10 is inserted in hole so that it is with traffic
Direction is consistent, seals hole with fluid sealant 15, and detection vehicle exists and passes through the time；The built-in magnetoresistive transducer of described detector
11, sense owing to vehicle disturbs the GEOMAGNETIC CHANGE caused, GEOMAGNETIC CHANGE amount is more than output high level, GEOMAGNETIC CHANGE during predetermined threshold value
Amount is less than output low level during predetermined threshold value；The outfan of described magnetoresistive transducer 11 is connected to timer, continues high level
Time carries out timing, and described high level lasting time is that vehicle passes through the time；Described wireless base station apparatus is connected to described timing
Device, is sent to upper receiver by the time by wireless network 20 by vehicle.
One specific embodiment of this utility model timer, in this embodiment, described timer includes constant-current source and electricity
Container, when timer receives high level, constant-current source charges to capacitor, when the magnitude of voltage correspondence vehicle at capacitor two ends passes through
Between.
Another specific embodiment of this utility model timer, in this embodiment, described timer includes enumerator, meter
Time device when receiving high level, enumerator starts counting up, and count value is multiplied by the counting cycle and passes through the time equal to vehicle.
Detector 10 of the present utility model is powered by battery, such as Li-SOCI2 3.6V battery, 57Ah.
Each detector can installation within 7-10 minute, installation process only needs specify position bore one straight
Footpath about 102mm, the hole of deep about 150mm, insert detector in hole so that it is consistent with traffic direction, finally close with earth magnetism
Sealing seals hole.
As it is shown on figure 3, the built-in wireless magnetoresistive transducer 11 of detector, the region that vehicle is put through wireless detector,
Owing to the existence of vehicle interior ferromagnetic material result in this magnetic field of the earth, region skewness, detector can detect due to car
Interference and cause magnetic field of the earth change.
Wireless vehicle detecting system of the present utility model, detector only need to drill through diameter 102mm-108mm, the degree of depth when installing
For the installing hole of 150mm, road pavement is destroyed little；Without threading, vertical rod, construct simple and convenient；Work progress takies the road surface time
Short；Surface deformation or out-of-flatness do not interfere with measurement effect, reduce maintenance workload；Such as pavement maintenance, can repeat after taking out
Use；Road surface canalization again also can be continuing with；It is short that maintenance process takies the road surface time；As single detector damages, only need to take
Go out maintenance, it is not necessary to again cut road surface, former installing hole can be continuing with.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
