[0002] As we all know, highways are important infrastructures that connect cities, villages and industrial areas, promoting economic development and people's travel. Along with the use of highways, they also need to be maintained.

In order to facilitate the determination of highway wear locations, we propose a pavement layer detection and calibration system for highway engineering.

[0003] After searching, the invention patent with Chinese patent application number CN202410424563.7 discloses a road surface thickness detection device for highway engineering, which is roughly described as comprising a remote control panel, a wireless control module is installed inside the remote control panel, a reference component, and the reference component includes a placement plate, a balance adjustment mechanism, a fixing cylinder, a penetration rod, a reference water pipe and a reverse mechanism, wherein the placement plate is placed on the ground through the balance mechanism, a circular hole is opened in the middle of the plate surface of the placement plate, and the penetration rod is slidably arranged in the circular hole, and the reference water pipe is connected with the penetration rod through the reverse mechanism. The movements are synchronous and in opposite directions. A fixing mechanism is provided on one side of the penetration rod to fix it.

[0041] The first visual camera 2, the second visual camera 3, the servo motor 6, the electric telescopic rod 8, the electric lifting rod 10, the variable frequency motor 22 and the optical detector 29 in this embodiment are all conventional equipment purchased on the market and known to those skilled in the art. In the present invention, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of their instruction manual and will not be described in detail here.

[0042] In summary, the working principle of the road surface layer detection and calibration system for highway engineering is that before use, the road surface layer detection and calibration system for highway engineering is firstly electrically debugged, and a central controller is equipped for the first visual camera 2, the second visual camera 3, the servo motor 6, the electric telescopic rod 8, the electric lifting rod 10, the frequency conversion motor 22 and the optical detector 29. The central controller can realize the recognition and processing of the collected information detected by the first visual camera 2, the second visual camera 3 and the optical detector 29, and convert the processed signal into the servo motor 6, the electric telescopic rod 8, the electric lifting rod 10 and the frequency conversion motor 22. The corresponding control signals are transmitted to the corresponding servo motor 6, electric telescopic rod 8, electric lifting rod 10 and frequency conversion motor 22. When in use, the first visual camera 2, the second visual camera 3, the servo motor 6, the electric telescopic rod 8, the electric lifting rod 10, the frequency conversion motor 22, the optical detector 29 and the central controller are equipped with a battery. The power device in the steering power wheel 45 is connected to the supply circuit of the central controller and the battery. When the steering power wheel 45 is running, the vehicle body 1 can move relative to the road surface. During the movement of the vehicle body 1, the first visual camera 2 quickly scans the road surface of the area where the vehicle body 1 passes, realizing the road The vehicle 1 moves slowly or pauses after reaching the abnormal area. The electric lifting rod 10 works to adjust the relative height of the lifting storage cylinder 9 relative to the vehicle 1, so that the optical detector 29 is close to the abnormal road area. The optical detector 29 emits a laser to scan the road surface. The basic principle of laser scanning the road surface gap is to calculate the distance between the road surface being tested and the scanning device by emitting a laser beam and measuring the time from the emission to the reflection of the beam. Through rapid and continuous scanning, the laser system can obtain a large amount of spatial data and form a high-precision Three-dimensional point cloud model, these data can be used to identify and analyze the cracks in the road surface, including geometric information such as the center, direction, width, length and depth of the cracks, so as to further identify and judge the abnormal road surface. During the identification and judgment process, the electric telescopic rod 8 is powered on to adjust the inclination angle of the swing frame 7 in the rotating frame 5, so as to facilitate the adjustment of the angle of the optical detector 29 relative to the road surface, and the servo motor 6 can realize the rotation adjustment of the rotating frame 5 relative to the fixed middle cylinder 4, so that the inclination direction of the swing frame 7 in the rotating frame 5 is adjusted, so that the optical detector 29 has a more suitable detection direction relative to the road surface.

[0043] Furthermore, if there are foreign objects on the road surface and it is inconvenient to judge the specific situation of the abnormal road surface, the frequency conversion motor 22 works to realize the rotation drive of the driving pulley 23, and the driving pulley 23 realizes the rotation drive of the driven pulley 25 through the synchronous belt 24. The rotation of the driven pulley 25 drives the rotating tube 21 to rotate, and the rotation of the rotating tube 21 drives the sliding tube 18 to rotate. The rotation of the sliding tube 18 drives the rotating brush cylinder 14 to swing through the elbow tube 17. Under the coordinated operation of the end face driving wheel 26 and the linkage gear 27, the rotating brush cylinder 14 will realize its own rotation relative to the elbow tube 17 during the swinging process, and finally reach the rotating brush cylinder 14. Different annular surfaces form active changes relative to the road surface, thereby improving the cleaning effect of foreign objects on the road surface, and also can improve the efficiency of the rotating brush cylinder 14. The utilization rate is adjusted. If necessary, a liquid supply pump and a liquid storage tank are installed for the external pipe. The liquid in the liquid storage tank is extracted by the liquid supply pump and sent to the external pipe, and is guided into the rotating brush cylinder 14 in sequence by the external pipe, the rotating pipe 21, the sliding pipe 18 and the elbow pipe 17. The liquid entering the rotating brush cylinder 14 is discharged through the liquid outlet 15. When the rotating brush cylinder 14 cleans the road surface, a cleaning liquid such as injection water is pre-added in the liquid storage tank to assist the bristles 16 on the rotating brush cylinder 14 to form auxiliary cleaning relative to the road surface. After the road surface inspection is completed, when corresponding marks are required to facilitate subsequent repairs, the rotating brush cylinder 14 is turned away from the lifting storage cylinder 9 to control the operation of the motor to realize a reciprocating swing of the double-headed driving frame 37, that is, the double-headed driving frame 37. After the top end first moves away from the swing frame 7 to the limit position, the double-head driving frame 37 approaches and resets again relative to the swing frame 7. During the process of the top end of the double-head driving frame 37 moving away from the swing frame 7, the upper limit plug block 39 is pulled out relative to the long strip mouth 41, and its limiting effect on the identification body fails. The lower limit plug block 40 is stacked in the lifting storage tube 9 to form an auxiliary limiting effect on the identification body. After the limiting effect of the upper limit plug block 39 on the identification body fails, the identification body will enter the area between the upper limit plug block 39 and the lower limit plug block 40. The lower limit plug block 40 limits the identification body. After the double-head driving frame 37 approaches and resets again relative to the swing frame 7, the upper limit plug block 39 is inserted into the lifting storage tube 9 again to The marking body above the identification body forms a second limit, and the limiting effect of the marking body that falls on the lower limit plug block 40 and is limited by the lower limit plug block 40 is invalid. The lower limit plug block 40 will not limit the original limiting marking body. The marking body is guided by the lifting storage cylinder 9 and finally falls on the ground. The marking body that falls on the ground is no longer squeezed by external force. Under the action of the elastic spring 33, the relative adsorption effect of the top suction cup 34 and the bottom suction cup 35 will be invalid, causing the overall structure formed by the base 31 and the top shell 32 to form a relative bounce and rise, so as to facilitate the formation of marking relative to the road surface, and finally facilitate identification and search during subsequent road surface maintenance. The second visual camera 3 can perform secondary recognition on the road surface processed by the rotating brush cylinder 14.The second visual camera 3 can also verify and judge the placement of the marker after placement.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
