Description
Technical field
The present invention relates to vehicle road gate field.More particularly it relates to a kind of intelligence prevents pounding banister and target detection
Method.
Background technology
Recently as flourishing for parking management industry, the application of road brake system also increasingly universalness, not only business
Industry building, office space can install automatic road brake system, even the closed residential area of some middle and high ends, comprehensive market etc. are daily
The entrance of life area has also gradually popularized automatic banister control system.
Banister is also known as railing, gate etc., be one kind by motor, limiter, mechanical arm, control panel, signal trigger device etc.
The vehicle of composition blocks equipment；It is most general in urban parking area access management, freeway toll station access management system
Time a kind of vehicle stop equipment.According to the difference of control mode, mechanical (manual), semi-automatic, self-action can be divided into.
Banister used at present usually first identifies testing vehicle register using modes such as video capture, brush IC card and completes to pay
Take, then by video camera identify control or money machine Keyboard Control pedestrian guardrail lift clearance vehicle, when vehicle by after banister
Railing put down automatically to block next payment vehicle.It is typically to use ground induction coil vehicle that the car excessively of banister falls bar control automatically
The realizations such as detector, echelette detector, also there is the technical solution using electromagnetic wave, ultrasonic wave etc. in recent years, but by
In the factors such as price height, stability difference constraint without popularize.It following is a brief introduction of these technologies of the prior art
Scheme and its it is respective the shortcomings that.
Fig. 1 and Fig. 2 respectively illustrates the signal of the automatic banister control program based on ground induction coil detection of the prior art
The schematic diagram of figure and its application scenarios.
As depicted in figs. 1 and 2, this scheme make use of electromagnetic induction principle, be felt with burying by falling bar region in gate
Coil, coil dimension are usually 2m*0.8m, and by coil access it is dedicated feel detector (electromagnetic relay), when vehicle (gold
Belong to body) it can cause the change of electromagnetism sensibility reciprocal when passing through ground induction coil, sense detector in ground is by analyzing the change indicator of electromagnetism sensibility reciprocal
To judge vehicle presence or leave；Detector is felt in the presence of vehicle and exports control panel dimension of the high level signal to automatic gate
The current lifting status of railing is held, ground feels detector and is switched to low level signal and controls gate to fall bar after vehicle leaves；Fall
When rear car follow-up or front truck reversing enter Coil Detector region during bar, coil checker is switched to high level and controls railing
Rising again prevents from pounding vehicle by mistake.
For this scheme based on this physical characteristic of electromagnetic induction, in normal work, the performance of detection vehicle is highly stable can
Lean on, be at present in automatic banister control field using a kind of most common detection control means.
However, this scheme is completely dependent on this sensing of ground induction coil and control device, brought just in the management to vehicle
Also problems with is brought while sharp：Ground induction coil is based on electromagnetic induction principle, and the only sensing to metal object is worked, no
The nonmetallic substances such as pedestrian, animal can be detected, it is also insensitive to the sensing of small-sized non-motor vehicle, mix the inlet and outlet occasion of row in people's car
In there are great insecurity.Almost most of parking lot all occurred pedestrian and passed through with car the accident injured by a crashing object.Ground sense
Coil checker is very sensitive to metallics, and the region of embedded coil cannot cause this with the presence of the metal object outside vehicle
Technology cannot adapt to the parking management scene that underground parking, sky parking etc. use steel construction originally.Ground induction coil is laid
Road is needed brokenly to construct, it is inconvenient not only to install and safeguard, also bigger to original pavement damage, especially in some vehicle flowrates
In big expressway tol lcollection track, because the problem of burying coil damage pavement structure, is also more prominent.Ground induction coil is embedded in
Underground, is easy to be subject to surface temperature to expand with heat and contract with cold and destroy caused by changing, and is once damaged and can not be sent out in time
Existing, the working status after it is damaged will become unstable, be easy to cause to fall bar or fall bar without reason and pound the serious problems such as car.Ground
It is also cumbersome that sense coil once damages its reparation, it is still desirable to first digs road surface and takes out old coil, then laying is new again
Coil can just resume work.
Fig. 3 and Fig. 4 is respectively illustrated the automatic banister control program detected based on echelette of the prior art and its answered
With the schematic diagram of scene.
Infrared detection is divided into the subdivision technology such as single-point type infrared induction and infrared emission detection again.Its technology is applied also
Through highly developed, the automatically-controlled door of such as present mansion, elevator anti-pinch, building automatic sensing illumination field are all widely used.
Vehicle detection based on echelette is exactly a kind of infrared emission detection technique；Mainly it is used in expressway tol lcollection system at present
In system, for providing front and rear car separated data for charging software.Echelette detection has more preferable adaptability, can not only
Detection car can also detect non power driven vehicle and pedestrian.Echelette is also known as electrical grating, infrared palisade；By infrared transmitter,
Receiver and control unit composition, are a kind of detection techniques realized based on active infrared line to penetrating technology；Generally use multi beam
For infrared light to penetrating, transmitter sends infrared light to receiver in a manner of " low frequencies and time-division are detected ".
As shown in Figure 3 and Figure 4, once have vehicle, pedestrian, non-motor vehicle through echelette appoint Ray Of Light when detect
Device sends presence signal, and exporting high level and controlling makes gate maintain state of arguing for the sake of arguing to automatic banister control panel；When car, people, non-
After motor vehicle leaves infrared beam, detector is switched to low level, and banister will fall bar automatically；If fall rear car during bar continue with
Into or front truck move backward when, system block again echelette then again export high level control gate argue for the sake of arguing, car was played with this
Fall bar and prevent pounding effect automatically.
Common infrared detection technology is not suitable for the vehicle detection and motive wave in parking lot since angle of coverage is larger
Lock controls.It is and as follows based on the automatic road brake system major defect of echelette vehicle detection：The horizontal covering surface of echelette is minimum,
Typically less than 1 centimetre, and banister back is can be only installed in order to avoid blocking, therefore, motor vehicle, non-motor vehicle, pedestrian are often
It is first to cross restrictor bar then can just be detected；If motor vehicle, non-motor vehicle, pedestrian follow front truck to be very easy to generation when robbing row and pound
Car, the accident hurted sb.'s feelings.Echelette detecting system price is of a relatively high, and complicated construction technique is, it is necessary in vehicles while passing track
Infrared transmitter and receiver are installed in vertical direction both sides respectively, usually also need to brokenly road threading and carry out transmitter and receiver
Wired connection could work normally.Echelette is the light curtain formed using multi-beam, early, the late interference for being vulnerable to sunlight, one
It is abnormal that denier has multi beam infrared light to occur, and system will operation irregularity.It is unobstructed in echelette detector requirement detection zone, can only
Installed in the inner side of lane guardrail, due to lacking protective device, equipment is easy to be broken by vehicle, the expense and work of later maintenance
Measure all very big.
Fig. 5 and Fig. 6 respectively illustrates automatic banister control program based on Electromagnetic Wave Detection and its application of the prior art
The schematic diagram of scene.
Electromagnetic Wave Detection generally includes several common technologies such as microwave detection, detections of radar, for stricti jurise, uses at present
Microwave technology is belonged in the electromagnetic wave of Vehicle Detection.It is to send energy wave from electromagnetic wave generator to detection zone, works as energy
Amount ripple when running into vehicle and reflects energy wave, electromagnetic wave vehicle checker by calculate energy wave transmitted value and reflected value,
Whether the indexs such as time determine the detection zone with the presence of parameters such as car, speed, vehicle numbers.
As shown in Figure 5 and Figure 6, detector exports high level in the presence of there is vehicle in banister Luo Gan areas, and gate maintains to argue for the sake of arguing
State；Vehicle leave rear detector be converted to low level signal control gate fall bar automatically；Fall during bar front truck follow-up or after
When car is moved backward, it is again converted to high level signal control gate and argues for the sake of arguing and prevent from pounding vehicle by mistake.
No matter traditional radar vehicle detector or microwave vehicle detector, be all based on electromagnetic impulse testing principle
Realize, its main problem is as follows：Vehicle can be accurately detected, but since radar wave, microwave possess certain penetrability, it is right
People, the detection of animal are insensitive, and therefore, when being controlled for automatic banister, there are height thing when generation people, animal are walked with car
Therefore hidden danger.Equipment debugging inconvenience, electromagnetic wave have invisibility, and radar, microwave detector usually have larger coverage,
Reach that can prevent pounding car and stop rear car well will not be frequently with car fee evasion, it usually needs professional carries out continuous
Debugging.Radar wave and microwave are a kind of electromagnetic waves, prevent pounding car test and surveying needing radar, microwave horizontal aligument payment track, people's row to lead to
Road detects, and therefore, has certain hazards of electromagnetic radiation to passer-by.Radar, microwave detector price are high, current general
It is generally relatively low to lead to the price level of automatic gate, being averaged for gate system will be greatly improved according to radar, microwave detector
Price, is unfavorable for the promotion and popularization of system.
Fig. 7 and Fig. 8 respectively illustrates automatic banister control program based on ultrasound examination and its application of the prior art
The schematic diagram of scene.
Ultrasonic wave is the sound wave that a kind of frequency exceedes 20000HZ, is a kind of mechanical wave；Its measuring principle and electromagnetic wave class car
Detection technique is similar, and typically using the reflectivity of sound wave and the penetrability of ultrasonic wave, ultrasound is sent to ultrasound examination area
Ripple, can be produced when ultrasonic wave runs into car, people, non power driven vehicle it is different degrees of penetrate and reflect, detector passes through to ultrasound
Ripple returns to energy value, the index such as time analyzes the car, people, the non power driven vehicle etc. that are detected.
As shown in Figure 7 and Figure 8, when detection zone maintains state of arguing for the sake of arguing, car there are high level signal gate during vehicle, is sent
, people, non-motor vehicle when sailing out of detector be converted to low level control gate and fall bar；Fall rear car, people, non-motor vehicle during bar
When being follow-up to detection zone, detector is switched to high level again, and gate stops falling bar and lifting automatically preventing pounding effect to play.
Sonic detection technology is the most universal in medicine detection and engineering construction field application, is introduced in parking management field
Ultrasound examination is then thing in recent years, is mainly used in the parking stall measure of large parking lot, is just had in motive wave in the recent period
The problem of case applied in lock control, it is primarily present, is as follows：Ultrasonic wave is the mechanical wave sent with certain frequency, and being adapted to should
For in spacious, quiet working environment, ability to be more preferable by the way of a high position covers downwards when being used as wagon detector
Play a role, and be used for needs during gate control and using being horizontally mounted mode, launched due to can not accurately modulate its signal
Scope, therefore, is easy to receive the interference of non-track one skilled in the art, non-motor vehicle etc..The easy wind-engaging of ultra sonic vehicle detector,
The influence of the unfavorable weather environment such as rain, snow, its detection range is small, and accuracy of detection is not high.
Therefore, subproblem present in the above-mentioned technical proposal least for the solution prior art is, it is necessary to propose new
