Description
Technical field
The utility model relates to the inspection machine field of the velocity-measuring system accuracy of highway hypervelocity automatic monitoring system, a kind of verifying attachment that can be suitable for existing any speed-measuring system of highway of saying so more specifically.
Background technology
Any gauging instrument all must guarantee its value accurately and reliably by the mode of calibrating or calibration.The automatic monitoring system for automobile overspeed that highway is used also is a kind of of gauging instrument, and main composition comprises test the speed, take pictures evidence obtaining and data management module.But because the speed-measuring method of such system applies is many, textural difference is very big, as the measuring principle that generally uses at present radar meter based on the Doppler shift principle is arranged; Or measuring vehicle consumed time during through the stretch journey, with distance/time measurement speed; Or video frequency speed-measuring etc.Used sensor has comprised radar wave detecting device, toroid winding detecting device, video detector, ultrasonic detector, infrared detector, pressure transducer, laser sensor etc.When this type systematic of calibrating tests the speed accuracy at present, need design the special testing instruments and the method for inspection at different speed-measuring methods.
According to the measuring principle design Special Survey equipment and the method for inspection, with gauged distance and standard time check or with the method for standard speed device check, device itself manufactures and designs, checkout procedure is all very complicated, and efficient is very low.As examine and determine radar wave detecting device velocity-measuring system, just need carry special radar velocity measurement standard set-up.Simultaneously, automatic monitoring system for automobile overspeed all is installed on the traffic main artery, by above calibration method, often needs road closure, perhaps system-down check.The human and material resources that relate to are very huge, even may not realize sometimes.
The utility model content
Numerous for solving traditional method of inspection equipment, and can not be implemented in the deficiency of X-ray inspection X, the utility model has designed a kind of verifying attachment of novel speed-measuring system of highway.Its target is to make its detectability not limited by the measuring principle of object, can the system that adopt existing any measuring principle be tested; Can realize " online " check, promptly not influence the current user mode of system in the checkout procedure; And improve calibrating efficient.
The utility model is achieved through the following technical solutions its purpose.
The utility model has designed a kind of verifying attachment of speed-measuring system of highway, mainly comprise speed measuring module, data processing module and display module three parts on the structure, the mutual data communication of above-mentioned three parts connects, speed measuring module and data processing module are located on the motor vehicle, and display module is located at outside visible position on the motor vehicle.Principle of work of the present utility model is by the real-time speed in the speed measuring module acquisition motor-driven vehicle going, handles the back by data processing module and is presented at outside visible position on the car body by display module.Because the present speed-measuring system of highway that no matter adopts the sort of principle mechanisms in the process that writes down automobile overspeed, all is that the mode that employing is made a video recording or taken a picture is collected evidence to the motor vehicle that exceeds the speed limit, and write down the motor vehicle speed value when collecting evidence.When being equipped with in the process that inspection vehicle of the present utility model travelling, speed-measuring system of highway can write down the speed of inspection vehicle and make a video recording or take a picture.Because above-mentioned display module is located at outside visible position on the car body, so shooting or photograph can be write down the real-time speed of the motor vehicle on the display module simultaneously.The contrast inspection vehicle speed that measures of speed-measuring system of highway and the real-time speed of inspection vehicle just can be checked the accuracy of speed-measuring system of highway.Because the course of work of the utility model device need not to depend on the principle mechanisms of speed-measuring system of highway, therefore can be applicable to the speed-measuring system of highway of any principle mechanisms.In the utility model course of work, inspection vehicle travel with the general vehicle that on highway, travels without any difference, therefore can realize " online " check, need not to handle especially to being verified the track, as isolate, road closure or the like, the human resources of calling also only are automobile drivers, thus existing relatively checking system brief greatly checkout procedure, saved big quantity of material and human resources, and can the highway system in the running not impacted.Use checkout procedure of the present utility model very simple, only need that form gets final product on the highway section being verified by inspection vehicle, efficient is very high.Can be verified on the highway section in same by an inspection vehicle repeated travel, or by the multi-section inspection vehicle same highway section that is verified of travelling simultaneously, obtain multi-group data, lot of data can guarantee the accurate evaluation to speed-measuring system of highway, and help system's adjustment in troubleshooting of faults and inaccurate monitoring highway section, increase work efficiency greatly.
