Description
Technical field
The invention discloses a kind of Internet of Things intelligent expressway hypervelocity monitoring system, relate to Internet of Things technical field of intelligent traffic.
Background technology
Highway velocity-measuring system of the prior art mainly comprises following several:
The first, radar velocity measurement: be a transmitting set, a receiver adds a comparer, a high-frequency signal is launched by transmitter and directional antenna, then signal projects the automobile automobile in traveling is metal, signal is returned the received machine of a part by automobile and receives, comparer calculates the mistiming of transmitting and receiving, and then launches and return reception again and ceaselessly compare, as long as the mistiming of comparing twice just can calculate speed.Be aided with the monitoring system that suitable Taking Pictures recording transmission system just constitutes various principle again.
The second, laser velocimeter: laser velocimeter principle is also referred to as laser radar principle (Ladar, LaserDetectionAndRanging), the i.e. meaning of laser interception and range finding.Ladar equipment adopts infrared semiconductor laser diode to launch the extremely narrow light beam of certain frequency and to take accurate aim target, decides speed by measuring the delivery time of infrared light-wave between Ladar equipment and target
The third, ground sensing coil speed measuring generally will use two coils, and between two coils, region is hypervelocity monitored area.Can produce electromagnetic induction in circuit when motor vehicle enters first coil, triggered timer starts timing simultaneously; After walking out second coil, timing terminates, and produces the mistiming of induction according to the Distance geometry between two coils, just can calculate vehicle by speed during hypervelocity monitored area with distance divided by the time.
4th kind, video frequency speed-measuring, the video principle monitoring system that tests the speed is virtual coil video frequency speed-measuring system, namely on the track in video image, establish two virtual coils at a distance of (30-50) m place, the speed due to camera acquisition image is certain (x second/frame), can obtain elapsed time by the frame number calculating picture, utilize vehicle by the mistiming of two virtual coils, just can draw the travelling speed 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 can reach tens milliseconds.Narrow beam advanced capabilities radar is more suitable for monitoring bicycle road overspeed situation compared with early stage widebeam radar.The emitting radar waves coning angle of wide velocity of wave radar is generally between 10 °-30 °, scanning plane is wider, monitored area is large, when adjacent lane two car enters hypervelocity monitored area side by side or enters hypervelocity monitored area continuously with track two car, which rule-breaking vehicle is radar observation system clearly cannot assert, is easy to cause mistake to grab erroneous judgement.The time of testing the speed of widebeam radar is generally hundreds of millisecond, and therefore, the too high vehicle of the speed of a motor vehicle just can measure its speed after the segment distance of monitored area one, at this moment may have little time to catch its image information, thus cause the situation of Lou grabbing or grabbing by mistake.Therefore, widebeam radar is not suitable for one-lane vehicle-speed monitoring system.
Laser velocimeter: relative to radar, laser velocimeter product price is higher.
Ground sensing coil speed measuring: can road surface be destroyed when being installation, affect pavement life, and coil is easily affected by environment and alteration of form occurs in underground, also by damages such as heavy vehicle extruding, road surface repair, use 2-3 just to need more emat coil, actual maintenance 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 test the speed to of a track car, two cars or several cars cannot test the speed through out-of-date simultaneously, more cannot differentiate whether it exceeds the speed limit.Because erroneous judgement vehicle is more and range rate error is too large.
Lack one in prior art and more improve highway speed measuring and monitoring device easily.
