Abstract
A system for preventing the follow-chase-behind collision on expressway features that digital scale units with a unique address code and radio transmitting-receiving function are arranged along the expressway at intervals; microwave or infrared ranging sensors for judging the corresponding lane, digital communication and processing signals are arranged transverse to the expressway at intervals, and radio transceivers and electronic ID are installed on each car. When two cars on the same lane approach each other to a limited distance, a warning signal is transmitted to them.
Description
Technical field
The present invention relates to highway or similar applications to avoid automobile in hot pursuit, and technological facilities is simple, cheap, a kind of collision avoidance system of easy enforcement.
Background technology
Be accompanied by Freeway Development, traffic hazard also grows with each passing day, and has become life-threatening major issue.For this reason, the highway automobile anti-collision technique has been carried out big quantity research both at home and abroad.As:
1, ultrasonic ranging collision avoidance system:
Ultrasonic transmitter constantly sends signal, runs into barrier-automobile back reflection and returns, and ultrasonic receiver receives signal, and the mistiming of measuring and transmitting is because hyperacoustic speed is known, so distance just is easy to obtain.Ultrasonic velocity is subjected to wind speed and temperature effect bigger, therefore with the run at high speed spacing of automobile of ultrasonic measurement certain difficulty is arranged.Japan has succeeded in developing model machine, but does not drop into practical.
2, laser automobile collision avoidance radar:
Utilize the laser radar ranging technology, make the device that prevents to knock into the back and collide, distance accuracy and track resolution are all very high.Because light beam is very narrow, sweep velocity is slow, must take the special technique measure, is subjected to the influence of various light sources, weather bigger in addition, and such as the influence of sunshine, cost is also higher in addition.
3, microwave automobile collision avoidance radar:
Utilize electromagnetic signals, return when running into the place ahead barrier-automobile back reflection, receiving trap is received echoed signal, record the mistiming between transponder pulse and the received pulse, microprocessor can calculate distance between two cars, output alarm signal or by control circuit, the servo-drive system control speed of a motor vehicle or brake.The microwave automobile collision avoidance radar, existing mature technology, having developed model machine as Braunschweig, Germany polytechnical university tests successfully, get up to exist some problems but promote, as the wave beam broad, be subject to disturb, cost is also higher, if the material of target carriage be not metal, reflected signal can be very weak, brings difficulty to range finding.
4, utilize GPS and other sensor technologies location.The GPS technology mainly is the range finding overlong time, does not satisfy crashproof requirement.
Various in sum schemes all must be loaded onto collision avoidance system at each automobile, and this is to existing vehicle, the especially situation of China's automobile, unrealistic, the dress that has, and what have does not adorn, and is difficult to play prevent the effect that knocks into the back.
Summary of the invention
The objective of the invention is to avoid weak point of the prior art, and provide a kind of automobile of avoiding in hot pursuit, technological facilities is simple, cheap, the intelligent digital scale system for preventing collision of cars on expressway of easy enforcement.
Can take following technical scheme to realize purpose.
Intelligent digital scale system for preventing collision of cars on expressway comprises receiver and transmitter; Be decided to be the x direction along highway, vertical highway direction is decided to be the y direction, establish wireless receiving and dispatching digital scale device at a certain distance in the x direction, each digital scale is established unique address code, dress wireless transmitter electronic ID card on the automobile, the position of automobile can digital scale address code represent; The y direction is spaced a distance and adorns infrared or the tellurometer survey sensor, judges corresponding track, carries out digital communication and signal Processing.When judging in same track or different track, and within limiting distance the time, send alarm signal or brake by data center and automobile communication.
The relative prior art of the technical program has following advantage and effect:
The digital scale scheme needn't increase each automobile fixed equipment, and total investment is lower, promotes easily, can realize the management of intelligent high speed highway, can realize crashproof function simultaneously, and not be subjected to climatic influences basically; Above-mentioned the scheme of narrating a direction, driving in the wrong direction also is suitable for, and just slightly has any different on the address, can not form the phase mutual interference; Communication between the digital scale device can be adopted wired or wireless mode, and therefore adopting Bluetooth technology is very easily, communicates by letter to control center at a distance and can adopt optical fiber or communication.Present technique extends on other roads, as ordinary road especially hill path, has very big social benefit and economic benefit.
Description of drawings
Accompanying drawing is the intelligent digital scale system for preventing collision of cars on expressway synoptic diagram.
Embodiment
In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.
1, intelligent digital scale system for preventing collision of cars on expressway comprises receiver and transmitter; Be decided to be the x direction along highway, vertical highway direction is decided to be the y direction, establishes wireless receiving and dispatching digital scale device at a certain distance in the x direction, and every digital scale is established unique address code, dress wireless transmitter electronic ID card on the automobile, the position of automobile can digital scale address code represent; The y direction is spaced a distance and adorns infrared or the tellurometer survey sensor, judges corresponding track, carries out digital communication and signal Processing.
2, intelligent digital scale system for preventing collision of cars on expressway, on 1 scheme basis, alarm signal is flashing light or blows a whistle or control center's communication alarm.
Transmitting-receiving and signal processing apparatus digital scale equally spaced are set on highway, and each digital scale is provided with unique address code, and the address code of the position of automobile on can digital scale represented.When vehicle passes through the highway crossing, provide a R-T unit for each car, regain again when going out highway, this R-T unit has unique electronics " I.D. " number, distinguishing mark as automobile, vehicle constantly sends signal-identification card number and communicates by letter with the R-T unit of digital scale when running on expressway, digital scale (address code) and the electronic ID card number synthetic accurate position of just having determined any vehicle like this, between the digital scale by wireless or wire communication, handle through data-signal, so just be easy to measure the spacing and the speed of adjacent vehicle, the positional information of the result that digital scale will record-front and back vehicle sends.If spacing is just dodged green light greater than 150m, confirm normal; If spacing is just dodged amber light less than 150m greater than 100m, the affirmation spacing is crossed closely and should be taken measures; If spacing during greater than 50m, is just being dodged red light less than 100m, should take urgent the deceleration or brake; If will take special measure less than 50m, otherwise can be dangerous.
Car accident just might take place in same lanes in vehicle, if not in a track, even hour also belong to cruising in spacing.On digital scale, also to increase the range finding of y direction for this reason.On the direction of vertical track, be spaced a distance, infrared or the tellurometer survey sensing device of one cover is installed, precision prescribed is not high, as long as can determine on which road, recording data, the electronic ID card number, address digit carries out data-signal together to be handled, and passing to data center, data center just can grasp the whole circumstances like this, and can communicate with each car.
