Description
Technical field
The utility model relates to a kind of road video tracking device that tests the speed.
Background technology
Along with the fast development of urban highway traffic cause, the urban transportation speed of a motor vehicle is increasing, if dredge ineffectively, will cause and block up.Implementing the monitoring urban highway traffic speed of a motor vehicle, is very important to guiding, relieving traffic congestion, and therefore, basically all is provided with the vehicle-speed monitoring device in major trunk roads and the main traffic location in city.Adopt in the underground mode of imbedding speed of a motor vehicle magnetic test coil at present, but it is the Shortcomings part also, such as destroying road surface etc. in the process of installation, coil can be because of environmental impact generation deformation when underground, and can be subject to heavy vehicle damage to different modes such as its extruding, road surface repairings when road traveling, within the time of 2-3, just need so in time changing of coils to be processed, seriously increased correlative charges; And the image of capturing is flashy overspeed situation often, has the situation of certain erroneous judgement, then can avoid this misjudgment phenomenon if can carry out video capture; So how to provide a kind of degree of accuracy high, the swift video tracking device that tests the speed, it is the technical barrier of this area.
The utility model content
The technical problems to be solved in the utility model provides high, the swift road of a kind of degree of accuracy video tracking device that tests the speed.
In order to solve the problems of the technologies described above, the utility model provides a kind of road video tracking device that tests the speed, and comprising: the drive over the speed limit camera head of vehicle of speed measuring device, track up; Described speed measuring device comprises: tachogenerator, link to each other with tachogenerator in order to calculate the speed of a motor vehicle and to lock the MCU module of over-speed vehicles; Described camera head comprises: the driving circuit that links to each other with described MCU module, and the stepper motor that links to each other with described driving circuit, with the turntable that this stepper motor is in transmission connection, described turntable is provided with video camera.
Further, for accurate measurement, described tachogenerator is laser sensor or magnetoresistive transducer.
Technique scheme of the present utility model has the following advantages compared to existing technology: (1) this device is small and exquisite, is easy to carry, and conveniently puts in the roadside, road, has improved the disguise that tests the speed; (2) adopt turntable control video camera to rotate, can effectively follow the trail of tested vehicle; (3) carry out video capture, the misjudgment phenomenon that can effectively avoid photo violating the regulations to occur, and the driver when disputable when transferring violation phenomenon, more directly perceived.
Description of drawings
For content of the present utility model is more likely to be clearly understood, below the specific embodiment and by reference to the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the test the speed electrical block diagram of video tracking device of road of the present utility model;
Fig. 2 is the electrical block diagram of speed measuring device of the present utility model;
Fig. 3 is the electrical block diagram of camera head of the present utility model.
Embodiment
The present invention is described in detail below in conjunction with drawings and Examples:
Embodiment 1
See Fig. 1 to 3, a kind of road video tracking device that tests the speed comprises: the drive over the speed limit camera head 1-2 of vehicle of speed measuring device 1-1, track up; Described speed measuring device comprises: tachogenerator 101, link to each other with described tachogenerator 101 in order to calculate the speed of a motor vehicle and to lock the MCU module 102 of over-speed vehicles; Described camera head comprises: the driving circuit 201 that links to each other with described MCU module 102, and the stepper motor 202 that links to each other with described driving circuit 201, with the turntable that this stepper motor is in transmission connection, described turntable is provided with video camera.
Tachogenerator can adopt laser sensor, magnetoresistive transducer or infrared ray sensor; Perhaps adopt radar velocity measurement.
In order to improve image processing speed, improve the precision of locking vehicle, described MCU module adopts the DSP module, also can adopt the ARM module.
Video camera is taken the road surface vehicle condition in real time, when if described tachogenerator 101 detects a certain overspeed of vehicle, this vehicle that is then locked in the camera views by described MCU module 102, and control described stepper motor 202 these vehicles of drive video camera track up of described driving circuit 201 drivings.
Obviously, above-described embodiment only is for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
Claims (2)
1. road video tracking device that tests the speed is characterized in that comprising: the drive over the speed limit camera head of vehicle of speed measuring device, track up;
