Embodiment Construction
[0026] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0027] refer to Figure 1 to Figure 9 , the lighting test system of the vehicle-mounted active visual detection system for cracks based on friction wheels includes a detection board 1, a detection box 2, an I-shaped lamp holder 3, a moving guide groove 4, a friction wheel 5, a motor 6 and an LED light 8.
[0028] The detection box 2 is a box-type part welded by five rectangular steel plates. A round hole is processed on the bottom steel plate, and a slender groove connecting the round hole and the side of the detection box 2 is processed on the lower surface of the bottom steel plate. The detection box 2 is placed on On a level ground, the motor 6 is an AC motor with a set of threaded holes processed on the base, and the friction wheel 5 is a disc-shaped part made of rubber with a keyway in the inner hole and a rough outer surface. The friction wheel 5 is set on the ou...

The invention discloses a light test system of a vehicle-mounted pavement crack active visual inspection system based on a friction wheel, and aims to solve the problem of light test of the vehicle-mounted pavement crack active visual inspection system based on the friction wheel. The light test system of the vehicle-mounted pavement crack active visual inspection system based on the friction wheel is mainly composed of a detecting board (1), a detecting box (2), an I-shaped lamp holder (3), a movable guide slot (4), the friction wheel (5), a motor (6) and LED lamps (8); and a middle cylinderof the I-shaped lamp holder (3) is slidably connected with an elongated straight slot in the upper side of the movable guide slot (4) in a fit manner, and an elongated slot of a rectangular iron pieceat the bottom of the I-shaped lamp holder (3) is in surface contact with the surface of the friction wheel (5). The light test system of the vehicle-mounted pavement crack active visual inspection system based on the friction wheel has the advantages of small occupied space, the simple structure, high detection accuracy, easy operation, easy installation, lower cost and reliable performance.
Description
technical field [0001] The invention relates to an auxiliary device for detection equipment in the field of traffic detection, more specifically, it is an illumination test system for a vehicle-mounted crack active visual detection system based on friction wheels. Background technique [0002] my country's highway construction has made great progress in recent years, but there have also appeared many pavement diseases, such as damage, cracks, settlement, etc. Pavement cracks are one of the most common and main diseases of highway pavement. Cracks not only affect the appearance of the road surface and reduce the smoothness, but also shorten the service life of the entire road surface and cause safety hazards to driving vehicles. Therefore, a vehicle-mounted road surface crack detection system is required to detect road surface cracks. However, the changes in the lightness and darkness of pavement cracks caused by different lighting conditions will affect the accuracy of the c...
