Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] Such as figure 1As shown, the device of the present invention mainly includes: a speed measuring device 1 , a data processing device 2 and a display device 3 , and is provided with a data output device 5 and a working parameter selection keyboard 6 . Wherein, the speed measuring device 1 is a non-contact speed measuring device, which can provide a measuring device for the instantaneous speed of the vehicle. Generally, an air sucker or a magnetic sucker or other fixing devices are installed on the outside of the inspection vehicle 4, such as a non-contact vehicle speed sensor, a radar speedometer, a laser sensor, etc.; or inside the vehicle, such as a radar speedometer, a laser sensor, a GPS speedometer, etc.; or The rear of the car, such as Wulunyi, etc. The data processing device 2 uses a single-chip microcomputer or a compatible computer to complete the calc...

Abstract

The invention relates to the field of inspection equipment for the accuracy of the speed measurement system of the highway overspeed automatic monitoring system. In order to solve the problem that the traditional inspection method has a large number of equipment and cannot realize online inspection, the invention designs a new type of inspection method for the road speed measurement system and its device. The structure of the device mainly includes three parts: speed measuring device, data processing device and display device. The above three parts are connected by data line communication. The working principle of the present invention is to obtain the real-time speed of the inspection vehicle during driving through the speed measuring device, and display it on the externally visible parts of the vehicle body by the display device after being processed by the data processing device.

Description

technical field [0001] The invention relates to the field of testing equipment for the accuracy of a speed measuring system of a highway overspeed automatic monitoring system, and more specifically relates to a testing method and a device applicable to any existing highway speed measuring system. Background technique [0002] Any measuring instrument must be verified or calibrated to ensure the accuracy and reliability of its value. The overspeed automatic monitoring system of inspection vehicles for highways is also a kind of measuring instrument, and its main components include speed measurement, photo evidence collection and data management devices. However, due to the many speed measurement methods used in this type of system, the structure is very different. For example, the commonly used speed measurement principle is the radar speedometer based on the Doppler frequency shift principle; Time measurement speed; or video speed measurement, etc. The sensors used include...
