Description
Technical field
The utility model discloses a kind of Internet of Things intelligent expressway hypervelocity monitoring system, relate to Internet of Things intelligent transport technology neckTerritory.
Background technology
Highway velocity-measuring system of the prior art mainly comprises following several:
The first, radar velocity measurement: with being that a transmitting set, a receiver add a comparator, by transmitter and fixedTo high-frequency signal of antenna transmission, then the automobile automobile of signal in projecting and travelling is metal, and signal is returned to one by automobileThe received machine of part receives, comparator calculates the time difference transmitting and receiving, and then transmitting returns to reception again and ceaselessly compare,As long as relatively the time difference of twice just can calculate speed. Be aided with again suitable Taking Pictures recording transmission system and just formed various principlesMonitoring system.
The second, laser velocimeter: laser velocimeter principle be also known as laser radar principle (Ladar,LaserDetectionAndRanging), the i.e. meaning of laser interception and range finding. Ladar equipment adopts infrared semiconductor laser twoUtmost point pipe is launched the extremely narrow light beam of the certain frequency target that takes accurate aim, by measure infrared light-wave Ladar equipment and target itBetween delivery time decide speed
The third, ground sensing coil speed measuring generally will be used two coils, and between two coils, region is hypervelocity monitored area. WhenWhen motor vehicle enters first coil, can in circuit, produce electromagnetic induction, triggering timing device starts timing simultaneously; Walk out secondAfter coil, timing finishes, and according to the time difference of the distance between two coils and generation induction, just can divided by the time with distanceSpeed while calculating vehicle by hypervelocity monitored area.
The 4th kind, video frequency speed-measuring, the video principle monitoring system that tests the speed is virtual coil video frequency speed-measuring system, in video imageTrack on, establish two virtual coils at a distance of (30-50) m place, due to the speed of camera acquisition image be certain (x second/Frame), can obtain elapsed time by the frame number that calculates picture, utilize vehicle to pass through the time difference of two virtual coils, just canDraw the speed of service of vehicle.
All also there are some places not fully up to expectations in the mode that tests the speed conventional in prior art.
Radar velocity measurement: using more is a kind of narrow beam advanced capabilities radar, and its field angle is about 4 °-6 °, and the time of testing the speed canTo reach tens milliseconds. Narrow beam advanced capabilities radar is compared and is more suitable for bicycle road overspeed situation to enter with early stage widebeam radarRow monitoring. The radar wave transmitting coning angle of wide velocity of wave radar is generally between 10 °-30 °, and scanning plane is wider, and monitored area is large,In the time that adjacent lane two cars enter side by side hypervelocity Huo Tong track, monitored area two cars and enter continuously hypervelocity monitored area, radar monitoring systemWhich rule-breaking vehicle system cannot clearly assert, is easy to cause mistake to grab erroneous judgement. The time of testing the speed of widebeam radar is generally hundreds ofMillisecond, therefore, the too high vehicle of the speed of a motor vehicle just can be measured its speed after one segment distance of monitored area, at this moment may come notAnd catch its image information, thereby cause the situation of Lou grabbing or grabbing by mistake. Therefore, widebeam radar is not suitable for the one-lane speed of a motor vehicleMonitoring system.
Laser velocimeter: with respect to radar, laser velocimeter product price is higher.
Ground sensing coil speed measuring: can destroy road surface while being installation, affect pavement life, and coil is at the underground environment shadow that is easily subject toRing and alteration of form occurs, being also subject to the damages such as heavy vehicle extruding, road surface repairing, using 2-3 just to need more emat coil, realityMaintenance expense is higher than other speed measuring equipment
Video frequency speed-measuring: the topmost shortcoming of this measuring principle is that range rate error is large, is easily subject to the impact of the factors such as illumination; Secondly,All objects through virtual coil all go on record, and invalid data is many, erroneous judgement vehicle is many; Again, once can only be to a carA car in road tests the speed, and whether two cars or several cars cannot test the speed through out-of-date simultaneously, more cannot differentiate it and exceed the speed limit. Due toErroneous judgement vehicle is more and range rate error is too large.
In prior art, lack one and more improve highway speed measuring and monitoring device easily.
