Description
Technical field
What the present invention relates to is a kind of road monitoring equipment---embedded high clarity, numeral, network high speed pickup superspeed snapping (containing bayonet socket) system belong to intelligent transportation (ITS) technical field.
Background technology
In road monitoring, prior art adopts common camera technique (25 frame/second), system is made up of industrial computer 11, several video cameras 12, light filling equipment 13, radar 14 or coils (or Video Detection) and a cover corresponding software, see shown in the accompanying drawing 1, its operation principle is: radar 14 (or coil or video) detects vehicle and comes detection zone, and measures its speed, if hypervelocity, then capture, general unidirectional two-way traffic is with four video cameras 12.Wherein three record license plate images (guaranteeing the size and the picture number of license plate image) and color, record vehicle and color are recorded in data such as time of capturing, place, the speed of a motor vehicle the suitable place of image again.Usually, system also has image processing, compression, deposit, communication function.See the block diagram shown in the accompanying drawing 2 for details.
The overspeed snapping system of prior art remain problem and shortcoming: the one, can't obtain driver's picture rich in detail, night speed of a motor vehicle Gao Shigeng very; The 2nd, for hot-short, the hot-short on the highway particularly difficultly obtains accurately to trigger, difficulty get a distinct image (car plate and vehicle); The 3rd, front end is controlled with industrial computer, Windows operating system.Its shortcoming is that the hardware resource utilization of industrial computer is low, and the inherent shortcoming of Windows system manifests after 1 year in continuous operation, and promptly the speed of service is slack-off, and control precision reduces, and this stability to system, reliability are fatal; The 4th, the communication of image, data simple, reliable, in real time, undesirable aspect at a low price.
Along with the sustainable growth of World Economics, road constantly extends.Wherein China's highway total kilometrage has reached 40,000 kilometers, occupies the second place of the world; The vehicle total amount constantly increases, and the thing followed is the increase of traffic accident, and congestion in road is serious, and crime violating the regulations increases day by day.This has almost become the common fault of countries in the world.In order to contain this impetus, assure the safety for life and property of the people, in recent ten years, intelligent transportation has been developed in countries in the world, utilize multi-disciplinary high-new scientific and technical results such as light, mechanical, electrical, computer, communication, research and develop into the equipment and the system of aspects such as various monitoring, traffic data dynamic acquisition, management, wherein just comprise the overspeed snapping system.Because the development of ITS (intelligent transportation system, Intelligent Transportation Systems), road traffic condition has had very big improvement, and the rate that improved that the road is clear has reduced rate of failure, has effectively contained criminal offence violating the regulations.
Along with the raising of China's international status, the 2008 Beijing Olympic Games, Shanghai World's Fair in 2010, the Guangzhou Asian Games in 2012 all will be held in China.Traffic safety, anti-terrorism prevent that task probably is heavy especially, and it is clear that relevant department and user proposed since 2006 driver's face to be clapped, and this is a kind of technical challenge for overspeed snapping system and Gate System.Because for hot-short (speed of a motor vehicle is higher than 110Km/h) particularly night hot-short, existing system is clapped vehicle, car plate clear difficult, it is clear to clap people's face still more? for this reason, must be from new technical conceive, adopt new technology to solve, Here it is purpose of the present invention and task.
Summary of the invention
The objective of the invention is to overcome the shortcoming and defect that existing overspeed snapping system exists, and a kind of can satisfy user's the new demand and the direction of technical development are provided, can improve stability, the embedded high clarity of reliability, numeral, the network high speed pickup superspeed snapping system of system works.
The objective of the invention is to finish by following technical solution, this system includes a controller that designs, makes without industrial computer control, and linking to each other with this controller is connected to radar, narrow-pulse generator and high-speed camera head; Described controller is for adopting the high-speed controller HCR of the embedded software and hardware structure Linux operation system of software, that become by large scale integrated circuit design.
The continuous HD digital high-speed camera head that is connected to the CCD color image sensor of at least one employing mega pixel of described high-speed controller, this high-speed camera head is connected with video memory or Surveillance center with network or optical fiber.
The core of described CCD color image sensor has marked 300,000 pixels, as shooting with video-corder continuously, and 25 frame/seconds of frequency, and link to each other with the multichannel DVR, or match with software among the SDRAM and to use as Video Detection.
Described high-speed controller links to each other and is connected to without transformer, directly promote one times of voltage and will exchange 220 volts, to the main capacitance quick charge, hypervelocity discharges behind high voltage stabilizer, and impulse discharge current reaches thousands of amperes, and the telegram in reply time is less than the high light intensity narrow-pulse generator of high pressure of 1.5s.
Also link to each other on the described high-speed controller be connected to triggerings, the equipment narrow beam radar that tests the speed, or alternative with coil checker or video detector, to adapt to the requirement of many occasions.
The present invention compared with prior art, it can obtain the picture rich in detail of high definition, digitized hot-short, comprise vehicle, car plate, driver's appearance, and the color of image, comprised the full detail of vehicle, wherein driver's image is unavailable in the past or obtains once in a while also inadequately clearly, the definition of vehicle, license plate image has significantly raising, its meaning is that the automatic discrimination of car plate has significantly raising, can reach more than 96%, is higher than national sector standard; The level and the success rate of illegal vehicle comparison have also been improved; Improved the capture rate of vehicle image, can reach more than 98%; The present invention without industrial computer, has reduced power consumption at front end, can utilize Fei Nier lens solar cell for supplying power, and is significant to inter-provincial road monitoring bayonet socket remote, no civil power.Front end has reduced a lot of idle computer hardware resources without industrial computer, substitutes with embedded hardware HCR, has improved stability, the reliability of hardware; Software control system is without Windows operating system, and substitutes with linux system, improved system's long term operation stability and precision; The present invention has also reduced system's manufacturing cost, has improved cost performance.
