Description

A kind of intelligence prevents pounding banister

Technical field

The utility model is related to vehicle road gate fields.To prevent pounding banister more specifically, the utility model is related to a kind of intelligence.

Background technology

Recently as flourishing for parking management industry, the application of road brake system also increasingly universalness, not only quotient 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 vehicle identification 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 to block next payment vehicle automatically.The vehicle of crossing of banister falls bar control typically using ground induction coil vehicle 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 universal.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 automatic banister control program detected based on ground induction coil of the prior art The schematic diagram of figure and its application scenarios.

As depicted in figs. 1 and 2, electromagnetic induction principle is utilized in this scheme, is 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) by that can cause the variation of electromagnetism sensibility reciprocal during 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 gate is controlled to fall bar after vehicle leaves；It falls 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 accidentally pounding vehicle.

For this scheme based on this physical characteristic of electromagnetic induction, in normal work, the performance of detection vehicle is highly stable can It leans on, is to apply a kind of most common detection control means in automatic banister control field at present.

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, only works to the sensing of metal object, 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 vehicle In there are great insecurity.Almost most of parking lot all occurred pedestrian and passed through with vehicle the accident injured by a crashing object.Ground sense Coil checker is very sensitive to metallics, and the region of embedded coil cannot lead to this with the presence of the metal object except 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 expand with heat and contract with cold and destroy, and be once damaged and can not be sent out in time caused by by surface temperature being changed Existing, the working condition after damage will become unstable, be easy to cause not fall bar or fall bar without reason and pound the serious problems such as vehicle.Ground It is also cumbersome that sense coil once damages its reparation, it is still desirable to first dig road surface and take 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 as the subdivisions technology such as single-point type infrared induction and infrared emission detection.Its technology is applied also Through highly developed, such as the automatically-controlled door of 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 the data of front and rear vehicle separation for charging software.Echelette detection has better adaptability, can not only Detection vehicle 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 out 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 pass through echelette appoint Ray Of Light when detect Device sends out 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 vehicle, 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 output high level control gate argue for the sake of arguing, vehicle was played with this It falls bar and prevents 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 Vehicle, the accident hurted sb.'s feelings.Echelette detecting system price is relatively high, complicated construction technique, needs 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, it can only Mounted on the inside of lane guardrail, due to lacking protective device, equipment is easy to be broken by vehicle, the expense and work of later maintenance It measures 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 out energy wave from electromagnetic wave generator to detection zone, works as energy Amount wave when encountering vehicle and returns energy wave reflection, 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 vehicle, 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 maintenance is argued 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 vehicle is moved backward, it is again converted to high level signal control gate and argues for the sake of arguing and prevent from accidentally pounding vehicle.

Traditional radar vehicle detector or microwave vehicle detector, are all based on electromagnetic impulse testing principle It realizes, main problem is as follows：Vehicle can be accurately detected, but since radar wave, microwave have certain penetrability, it is right People, the detection of animal are insensitive, and therefore, when being controlled for automatic banister, there are height things when generation people, animal are walked with vehicle Therefore hidden danger.Equipment debugging is inconvenient, and electromagnetic wave has invisibility, and radar, microwave detector usually have larger coverage area, Reach that can prevent pounding vehicle and stop rear car well will not be frequently with vehicle fee evasion, it usually needs professional carries out continuous Debugging.Radar wave and microwave are a kind of electromagnetic waves, prevent that pounding car test survey needs 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 are at high price, current general The price level for leading to automatic gate is generally relatively low, and 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 is more than 20000HZ, is a kind of mechanical wave；Its measuring principle and electromagnetic wave class vehicle Detection technique is similar, and typically using the reflectivity of sound wave and the penetrability of ultrasonic wave, ultrasound is sent out to ultrasound examination area Wave, can be generated when ultrasonic wave encounters vehicle, people, non power driven vehicle it is different degrees of penetrate and reflect, detector passes through to ultrasound Wave returns to energy value, the indexs such as time analyze vehicle, people, non power driven vehicle for being detected etc..

As shown in Figure 7 and Figure 8, when detection zone maintains state of arguing for the sake of arguing, vehicle there are high level signal gate during vehicle, is sent out , 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 stopping falls bar and lifts automatically to be prevented 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 case applied in lock control, the problem of being primarily present, are as follows：Ultrasonic wave is the mechanical wave sent out with certain frequency, and being suitble to should For in spacious, quiet working environment, ability to be more preferable in a manner that a high position covers downwards when being used as wagon detector Play a role, and be used to need using being horizontally mounted mode during gate control, due to can not accurately modulate the transmitting of its signal Therefore range, 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, detection range is small, and accuracy of detection is not high.

Therefore, it least for subproblem present in the above-mentioned technical proposal for solving the prior art, needs to propose newly Intelligence is anti-to pound banister.
