Problems solved by technology

[0004] For the detection and evaluation of road surface smoothness and structural depth indicators, although advanced laser detection technology has been used so far, most of them are limited to these two indicators In addition, it only detects the flatness index on a wheel track belt, and it has not yet been able to conduct high-efficiency detection at the same time as other road surface quality indexes.
[0005] For the detection and evaluation of road rutting indicators, the main problem of the current laser detection device is that the number of laser probes installed in the cross-sectional direction is small, The detection width is smaller than the width of a driving lane, and the detection accuracy is low; in addition, the beams on which the laser probes are installed are often arranged outside the detection vehicle, and the width of the beams also exceeds the width of the detection vehicle, which is not conducive to driving safety
Generally speaking, the detection of road rutting indicators is still a separate detection, and it has not been able to perform high-efficiency detection at the same time as other road surface quality indicators
[0006] For the detection and evaluation of road surface cracks and other damage, at present, manual walking and visual record detection are mainly used, which has low detection efficiency, affects normal traffic and detection personnel However, the digital image detection methods that have been applied in recent years have not yet achieved high-efficiency detection at the same time as other road quality indicators.
In addition, the detection of road environment information is currently mainly carried out manually, which is inefficient and cannot achieve long-distance and large-scale detection.
[0007]Even if there are multi-road index detection devices that have been adopted at present, they are generally only a combination of several individual indicators, and the comprehensive detection of all indicators has not yet been realized. Therefore, its function and performance are also unsatisfactory.

Abstract

The invention relates to a highway road condition detection vehicle which can be used for detecting and evaluating a plurality of road quality indexes, comprising a vehicle body with an operation chamber. The front end of the vehicle body is provided with a laser probe which can detect the evenness and the structural depth and can emit collimation laser beams downwards; the upper part of the rear end of the vehicle body is provided with a road surface wheel track detecting and photographing camera and a road surface damage linear array camera; the rear lower part of the vehicle body is provided with a high power linear laser with a linear laser source direction adjusting rotating shaft; the lower part of the rear end of the vehicle body is provided with a linear array camera LED light-focusing illumination device; and the top part of the vehicle body is respectively provided with a road environment camera, a safety monitoring camera and a GPS positioning antenna. The operation chamber of the vehicle body is internally provided with a workbench, a generator, an industrial computer cabinet and a control circuit device. Compared with the prior art, the highway road condition detection vehicle has the advantages of novel structure, full function, convenient operation and high detection precision, and can achieve the comprehensive detection of a plurality of road quality indexes, and the like.

Description

technical field [0001] The invention belongs to the technical field of road quality detection equipment, and relates to a high-speed road condition detection vehicle that can be used to detect and evaluate multiple road quality indicators. Background technique [0002] In the construction, operation, and maintenance of high-grade highways, multiple quality indicators of the road, such as road surface roughness, structural depth, road rutting, road surface cracks, and various environmental information on both sides of the road (such as guardrails, slopes, Central isolation zone) and other indicators are very important for the construction department and traffic management department. How to quickly and objectively detect and evaluate the above indicators has long been a matter of great concern to relevant departments. [0003] At present, the current status of detection and evaluation of related road quality indicators in this field is as follows. [0004] For the detection...
