[0030] Embodiment 2

[0031] Please refer to Figures 1-5 , a multi-lane road surface disease area array scanning device, including a moving vehicle body 100. The moving vehicle body 100 has a motion assembly that can travel along the lane, including a moving wheel set, a driving motor, a battery unit, etc. A box body 200 is arranged on the moving vehicle body 100. An openable isolation door 210 is arranged on one side of the box body 200. Staff can enter the inside of the box body 200 by opening the isolation door 210 for maintenance and repair operations. An illuminating lamp body that can provide lighting is installed inside the box body 200. A frame groove is arranged at the tail end of the box body 200. An adjusting frame 220 is movably arranged on the frame groove. The adjusting frame 220 is rotationally connected to the frame groove through a rotating shaft. A detection mechanism 300 is arranged inside the adjusting frame 220. The adjusting frame 220 can form a fixed angle with the frame groove through a limiting mechanism 500;

[0032] The detection mechanism 300 includes a plurality of area array cameras. At least one set of sleeve rods 230 is fixedly connected to the adjusting frame 220. Preferably, two sets of sleeve rods 230 are provided. The sleeve rods 230 are rotationally connected to a ring plate 240. The ring plate 240 is eccentrically arranged with the sleeve rods 230. An extension mechanism 400 is arranged on the ring plate 240. The plurality of area array cameras are respectively installed on the extension mechanism 400 and the adjusting frame 220 for taking photos and scanning the multi-lane road surface;

[0033] A power source 250 is installed on the adjusting frame 220. A transmission assembly 251 is arranged at the movable end of the power source 250. The transmission assembly 251 is connected to the ring plate 240 for driving the ring plate 240 to pivot.

[0034] When detecting the diseases and damages of the carriageway pavement, the adjusting frame 220 is rotated out from the closed state in the frame groove. According to the brightness of the weather, the included angle between the adjusting frame 220 and the frame groove is continuously adjusted. After each rotation, the pavement photos taken by the area array camera are debugged until the diseases of the central carriageway pavement can be clearly seen in the photos taken by the area array camera. Then, the adjusting frame 220 and the frame groove are fixed at a certain angle through the limiting mechanism 500, so that scanning detection can be normally carried out under different weather lighting conditions without the need for auxiliary lighting during work. The power source 250 drives the ring plate 240 to pivot along the sleeve rod 230 to the side of the adjusting frame 220 through the transmission component 251. The stretching mechanism 400 stretches on the ring plate 240 to drive the area array camera to extend laterally. The moving vehicle body 100 travels along the road, so that the area array camera vehicle can take pictures and scan the three-lane pavement. By using the area array camera scanning technology, the multi-lane image fusion technology in the moving state and the imaging angle transformation technology, the software analyzes the collected data, automatically and quickly identifies, classifies and records the damage information of the pavement, effectively improving the efficiency of the scanning detection of the diseases and damages of the multi-lane pavement and realizing intelligent and efficient inspection.

[0035] In this embodiment, a control unit is arranged inside the box body 200. The control unit controls the moving vehicle body 100 to travel along the road through a wireless network, so that the area array camera continuously takes seamless pictures of the driving pavement to collect pavement images.

[0036] In this embodiment, an elastic layer is arranged outside the adjusting frame 220, which can be abutted against the frame groove when closed. When the multi-lane pavement disease area array scanning device is in a non-working state, the adjusting frame 220 is closed to prevent dust from entering the inside of the box body 200.

[0037] In this embodiment, the power source 250 is a telescopic structure, and the number of the telescopic ends of the power source 250 matches that of the sleeve rod 230, with two telescopic ends. Preferably, it is a double-directional electric control push rod. The transmission component 251 includes an arm rod. One end of the arm rod is hinged to the telescopic moving end of the power source 250, and the other end is hinged to the ring plate 240. The telescopic moving end of the power source 250 drives the ring plate 240 to pivot along the sleeve rod 230 to the side of the adjusting frame 220 through the arm rod, and the area array camera on the stretching mechanism 400 is debugged. Select a situation where the diseases of the lateral pavement can be clearly seen in the photos taken by the area array camera, so as to adjust the lateral extending position of the ring plate 240 relative to the adjusting frame 220. That is, under the drive of the power source 250 and the transmission component 251, the ring plate 240 can extend the same distance while having different lateral extending positions relative to the adjusting frame 220, so as to realize the precise scanning detection of the lateral road by the area array camera. When the ring plate 240 is in a non-working state, it is retracted to the inside of the adjusting frame 220 and is inside the box body 200 when the adjusting frame 220 is closed in the frame groove, which not only reduces the occupied space but also plays a good role in isolation and protection.

Specifically, by pressing the push block 550, when the push block 550 is stressed, it can compress the elastic member 560 to drive the chuck 541 to disengage from the card slot through the movable column. Rotate the adjusting frame 220 to the corresponding angle. By rotating the swing rod 530, align the chuck 541 with a set of card slots. Then release the push block 550. Under the elastic thrust of the elastic member 560, the movable column body 540 extends along the cavity 531 to drive the chuck 541 to be clamped in the card slot to fix the adjusting frame 220. The rotation source 440 drives the moving block 430 at the end to move along the ring groove 410 through the connecting rod 441. Under the action of the "V"-shaped rod 420 connecting the moving block 430, the "V"-shaped rod 420 extends along its midpoint, so that multiple moving blocks 430 move along the ring groove 410, driving the area array camera to extend.
