[0036] S1. Start the servo cylinder 14 to drive the connecting plate 15 to move, remove the cleaning brush 12 from the inside of the receiving groove 9, and adjust the height of the cleaning brush 12 to adjust the cleaning brush 12 to a position where the road surface can be cleaned;

[0037] S2. Start the servo motor 18 to drive the shaft 19 to rotate, the shaft 19 drives the turntable 11 to rotate, so that the turntable 11 drives the cleaning brush 12 to rotate;

[0038] S3. When the cleaning brush 12 rotates, the piston plate 24 reciprocates up and down in the cylinder 22, inflates the cylinder 22, discharges through the blowing hole 23, and blows the blowing hole 23;

[0039] S4. Start the carrier vehicle 1, before the rutting detection, the rutting position of the road surface is cleaned by rotating the cleaning brush 12 and blowing the air holes 23 to remove obstacles;

They are not the innovation points of the present application and will not be described in detail. Through the above process, before the rutting detection, the particulate impurities or obstacles in the rutting area can be cleaned up first, and the particulate impurities or obstacles can be cleaned out from the rutting area by rotating cleaning with the cleaning brush 12 and blowing with the blowing hole 23, so as not to affect the subsequent information collection process, thereby increasing the accuracy of signal collection.

[0042] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 8 , a road surface line laser rutting detection system based on image analysis, according to a road surface line laser rutting detection method based on image analysis, comprising a carrier vehicle 1, a distance measuring device 2 is fixed on the outer surface of the carrier vehicle 1, a roof connecting frame 3 is fixed on the top of the carrier vehicle 1, an equipment installation box 4 is fixed on the lower surface of the roof connecting frame 3, a collection camera 5, a data collection box 6 and a line laser 7 are installed in the equipment installation box 4, the collection camera 5 and the line laser 7 are electrically connected to the data collection box 6, and the data collection box 6 is electrically connected to a computer terminal 8 for analyzing images;

[0043] The outer surface of the carrier vehicle 1 is provided with a receiving groove 9, a lifting seat 10 is slidably arranged in the receiving groove 9, a turntable 11 is arranged below the lifting seat 10, a cleaning brush 12 is fixed to the lower surface of the turntable 11, the lifting seat 10 drives the cleaning brush 12 to be stored in the receiving groove 9 and to extend from the receiving groove 9 by lifting, and the turntable 11 drives the cleaning brush 12 to rotate by rotating to clean the road surface;

[0044] A driving groove 13 is provided inside the receiving groove 9, a servo electric cylinder 14 is fixed inside the driving groove 13, a connecting plate 15 is fixed to the output end of the servo electric cylinder 14, and the end of the connecting plate 15 is fixedly connected to the surface of the lifting seat 10;

[0045] Guide rods 16 are fixed on both sides of the lifting seat 10, and guide grooves 17 for the guide rods 16 to slide are opened on the inner wall of the receiving groove 9;

[0046] A servo motor 18 is fixed to the lower surface of the lifting seat 10 . A rotating shaft 19 is fixed to the output end of the servo motor 18 . The other end of the rotating shaft 19 is fixedly connected to the turntable 11 .

[0047] In the present technical solution, before rutting detection is performed, when the carrier vehicle 1 travels along the rutting, the servo electric cylinder 14 is first used to push the connecting plate 15 downward, and the connecting plate 15 drives the lifting seat 10 to move downward, and the lifting seat 10 moves downward to drive the cleaning brush 12 to move downward, and the cleaning brush 12 is moved to the road surface position, and then the servo motor 18 drives the rotating shaft 19 to rotate, and the rotating shaft 19 drives the turntable 11 to rotate, and the turntable 11 drives the cleaning brush 12 to rotate, so that the cleaning brush 12 cleans the road rutting position, and the rotation of the cleaning brush 12 is used to clean foreign particles or obstacles to both sides of the rutting, thereby preventing foreign particles or obstacles remaining on the rutting from affecting subsequent data collection.

[0048] In the third embodiment, when the cleaning brush 12 cleans the foreign particles or obstacles to both sides of the rut, the foreign particles or obstacles are not far away from the edge of the rut. When the carrier vehicle 1 is traveling, the foreign particles or obstacles are easy to re-enter the rut, thereby affecting the subsequent data collection and reducing the accuracy of the detection. To address this problem, this embodiment is an improvement based on the second embodiment. For details, please refer to Figure 1-Figure 8 A positioning disc 20 is sleeved on the outer side of the rotating shaft 19, a support column 21 is fixed between the top of the positioning disc 20 and the positioning seat, a plurality of groups of air cylinders 22 are arranged in a circumferential array on the upper surface of the rotating disc 11, and a blowing hole 23 connected to the air cylinder 22 is opened on the rotating disc 11, a piston plate 24 is slidably arranged inside the air cylinder 22, a movable rod 25 is fixed on the piston plate 24, and an annular slide groove 26 for the movable rod 25 to rotate is opened on the lower surface of the positioning disc 20, and the piston plate 24 performs a blowing process on the blowing hole 23 through up and down reciprocating motion;

[0049] A sliding protrusion 27 is fixed to the end of the movable rod 25, and a track groove 28 is opened on the inner wall of the annular slide groove 26. The sliding protrusion 27 is slidably arranged in the track groove 28, and the track groove 28 includes a horizontal part 2811, an ascending part 282 and a descending part 283 which are sequentially connected and arranged;

[0050] A pressure relief hole 29 is provided at the top of the air cylinder 22 , an air inlet hole 30 is provided at the bottom of the air cylinder 22 , a first one-way valve 31 is installed in the air inlet hole 30 , and a second one-way valve 32 is installed at one end of the air blowing hole 23 close to the air cylinder 22 .

[0051] In the present technical solution, when the cleaning brush 12 rotates, the air cylinder 22 rotates along with the turntable 11, and the rotation of the air cylinder 22 drives the movable rod 25 to rotate along the annular slide groove 26, and the movable rod 25 drives the sliding protrusion 27 to slide along the track groove 28, such as Figure 6 As shown, when the sliding protrusion 27 slides from the horizontal portion 281 to the rising portion 282 and slides inside the rising portion 282, the sliding protrusion 27 moves upward, driving the movable rod 25 to move upward, and the movable rod 25 drives the piston plate 24 to move upward. At this time, the first one-way valve 31 is opened and the second one-way valve 32 is closed, so that the inside of the air cylinder 22 is inflated, and the pressure above the piston plate 24 is relieved through the pressure relief hole 29; when the sliding protrusion 27 slides along the descending portion 283, the sliding protrusion 27 moves downward, driving the movable rod 25 to move downward, and the movable rod 25 drives the piston plate 24 to move downward. At this time, the first one-way valve 31 is closed, and the second one-way valve 32 is opened, so that the inside of the air cylinder 22 is exhausted, and the gas is blown out through the blowing hole 23, and the foreign particles on the ruts are further cleaned by the blown gas, thereby improving the cleaning effect of the foreign particles;

[0052] In this technical solution, two groups of track grooves 28 are provided, such as Figure 8 As shown, during the process of the blow hole rotating from a to b, and during the process of the blow hole rotating from c to d, it is a state of blowing outwards, when the cleaning brush 12 moves along the direction shown in FIG. Figure 8 When the direction is rotated, the impurity particles inside the rut can be swept to the blowing hole 23, and the impurity particles on both sides of the rut can be blown away through the blowing hole 23. In addition, the descending amplitude of the descending part 283 is larger than the rising amplitude of the ascending part 282, so that the air cylinder 22 exhausts air at a faster rate, thereby increasing the blowing rate of the blowing hole 23.

[0053] In the fourth embodiment, when the cleaning brush 12 cleans the impurity particles, the impurity particles will be concentrated on both sides of the rut. When the blowing hole 23 blows air, the impurity particles closer to b and d are more, resulting in poor cleaning effects of the two places under the same blowing conditions. To address this problem, this embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figure 1-Figure 8A longitudinal rod 33 is elastically arranged between the air cylinder 22 and the turntable 11, the top of the longitudinal rod 33 is arranged below the piston plate 24, a first abutment block 34 is fixed to the bottom end of the longitudinal rod 33, a plugging head 35 is arranged in the blowing hole 23, a cross bar 36 is fixed to the outer surface of the plugging head 35, the cross bar 36 is elastically arranged in the turntable 11, a second abutment block 37 matched with the first abutment block 34 is fixed to the end of the cross bar 36, and an inclined air guide block 38 matched with the plugging head 35 is arranged at the port of the blowing hole 23;

[0054] A first protrusion 39 is fixed on the outer surface of the longitudinal rod 33, a groove 40 is opened inside the turntable 11 for the first protrusion 39 to slide, a first spring 41 is arranged between the first protrusion 39 and the inner wall of the groove 40, a second protrusion 42 is fixed on the outer surface of the cross bar 36, and a second spring 43 is arranged between the second protrusion 42 and the inner wall of the blowing hole 23.

[0055] In the present technical solution, when the piston plate 24 moves downward to exhaust, first the piston plate 24 does not contact the longitudinal rod 33, so that the blowing hole 23 blows normally. When the piston plate 24 moves downward to two-thirds of the air cylinder 22, the piston plate 24 contacts the longitudinal rod 33. At this time, the piston plate 24 moves downward to drive the longitudinal rod 33 to move downward. The longitudinal rod 33 moves downward to stretch the No. 1 spring 41, so that the No. 1 spring 41 accumulates force. The longitudinal rod 33 moves downward to drive the first resistance block 34 to move downward, so that the first resistance block 34 conflicts with the second resistance block 37, prompting the second resistance block 37 to move to the right (such as Figure 7 As shown in the figure, the second abutment block 37 moves to the right, driving the cross bar 36 to move to the right. At the same time, the No. 2 spring 43 is stretched and stored. The cross bar 36 moves to the right, driving the plugging head 35 to move to the right, so that the plugging head 35 cooperates with the inclined air guide block 38 to reduce the opening of the blowing hole 23. The opening of the blowing hole 23 becomes smaller, and the flow rate of the blown gas increases, so that the blown wind force is greater, so that it is more convenient to blow away the impurity particles; when the piston plate 24 is reset upward, the No. 1 spring 41 and the No. 2 spring 43 release their forces, so that the plugging head 35 and the longitudinal plate are reset, and the opening of the blowing hole 23 is reset;

[0056] In the technical solution, the process of the opening of the blowing hole 23 becoming smaller is Figure 8 The point a is two-thirds of the way from point b to point c, and the point c is two-thirds of the way from point d to point d.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
