Existing vehicle speed measuring technological means is mainly as follows:
1, coil type tests the speed: be embedded with two groups of inductive coils under the road surface, when vehicle passed through, the distance of two groups of coils of user had just obtained the speed of a motor vehicle divided by the mistiming of detecting.
2, radar velocity measurement (microwave type tests the speed): the speed of measuring moving object by microwave, its work theory is based on Doppler's principle, namely when microwave irradiation to the motion object on the time, can produce a variation that becomes ratio with moving object speed, it changes the speed that size is proportional to object of which movement.
3, based on the vehicle speed measuring system of video: the road surface coordinate system that passes through to set up can compare accurate location to the position of vehicle in each two field picture, just can obtain the speed of a motor vehicle in conjunction with the frame frequency of video image.
But there is following shortcoming in above-mentioned vehicle speed measuring means:
1, equipment and input aspect: need to be equipped with the special equipment such as GPS terminal, transmission network and monitor supervision platform, its service time of battery is short, and the continuous use in not plug-in source generally only has 40 minutes to 1.5 hours; The location is inaccurate, and GPS normal plane positioning error is in 10-30 rice; The impact that is subject to the factors such as weather is larger, causes searching star or search star very slow.And the highway circuit is very long, if realize covering comprehensively, the equipment investment that needs is very huge.
2, accuracy aspect: radar will normally be brought into play speed measuring function, its must with the same path of tested vehicle, if there are certain angle in position and vehicle running path that radar is put, cause and vehicle route keeping parallelism always, the detected speed of radar will be slower than actual speed, and the speed that measures is the projection of actual speed on directions X of vehicle; Radar velocity measurement is vulnerable to the restriction of physical environment aspect, and some larger objects on road as buildings, billboard etc., all can have influence on the accuracy of radar velocity measurement; The metering system of sample-based, owing to being subject to the hits quantitative limitation, accuracy also is difficult to improve; There is shadow effect, when using way of patrol to measure, if cruiser and target carriage distance are very near, the microwave reflection intensity of the target vehicle that travels in the same way can replace the microwave of ground return, and make radar be difficult to the accurately identification patrol speed of a motor vehicle, at this moment, the patrol speed of a motor vehicle might be lost, and causes measuring error.
3, real-time aspect: the result that tests the speed of the existing means that test the speed is to inform the car owner by the mode of penalty note after speeding, cause the car owner just can know afterwards, can not remind at that time the car owner to exceed the speed limit, thereby in time adjust the speed of a motor vehicle, not have good effect for overspeed warning, accident prevention.
4, stable aspect: based on the vehicle speed measuring system of video, although can in most of the cases effectively identify and follow the tracks of vehicle, but vehicle is more or when the traffic congestion phenomenon was arranged, the vehicle target large tracts of land in foreground image was sticked together, for monitoring has increased difficulty on road; Simultaneously, on real road, situation is complicated, causes camera mechanical shaking, lightning to cause the acute variation etc. of light such as strong wind, has situation about much can't estimate to occur, and may cause the system within a certain period of time can't steady operation.
