Description

technical field [0001] The invention belongs to the technical field of road quality inspection equipment, and relates to a laser road comprehensive inspection 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 detectio...

AI Technical Summary

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.

[0008] In addition to the above-mentioned detection devices, there are still some shortcomings in the current road inspection vehicles in this field, which are specifically manifested in: the road surface damage lighting has not realized the adjustable inclined lighting mode; in the flatness detection, the low-speed detection cannot be realized. , can not stop at a slow speed at any time, it is not suitable for road detection in complex traffic situations, and it is also not suitable for detection of urban roads; the damaged lighting system outside the vehicle is often super wide, which is not conducive to the driving safety of the detection vehicle; the safety protection cabin on the vehicle The door opening has not been automatically controlled; the inspection vehicle does not have a large-size LED electronic display for driving safety warnings; the operation space in the inspection vehicle is small, and there are few auxiliary facilities in the vehicle (such as no drinking fountains, sinks, etc. for operators to use). rest position, etc.), which is not conducive to the long-term comfortable work of the staff; the design of the work position in the car often prevents the operator from facing the front of the vehicle, causing the operator to work for a long time and feel unwell; the computer and other equipment in the car are installed scattered, which is not conducive to equipment upkeep and maintenance
