[0002] As asphalt roads are often crushed by vehicles and affected by the natural environment, the road surface structure is often damaged. Remote sensing monitoring technology can be used to detect the status information of asphalt roads. For example, laser remote sensing technology, the laser emitted by the transmitter is reflected by the road surface and received by the receiver. After the processor processes the data, it can analyze whether there are cracks, potholes and other undesirable phenomena on the asphalt road surface.

However, when the vehicle is driving to the target section, the environment along the way is not controlled by humans. Especially for mountain roads, objects often fall onto the surface of the vehicle, such as fallen rocks, branches, etc., which can easily cause the monitoring device to be damaged by objects, resulting in large economic losses.

[0045] like Figure 8 As shown, a method for using an asphalt pavement remote sensing monitoring device, the method adopts the asphalt pavement remote sensing monitoring device, and the method comprises the following steps:

[0046] S1: driving the vehicle to the target road section, controlling the driving shaft 3 to rotate through the power assembly, and rotating the support arm 4 to the outside of the protective cover 2, so that the support arm 4 extends outward;

[0047] S2: Rotate the monitoring head 5 and adjust the angle, emit laser light through the laser transmitter 6, and receive it after being reflected by the road surface by the laser receiver 7, and then analyze the status information of the asphalt road surface;

[0048] S3: After the monitoring work is completed, the support arm 4 and the monitoring head 5 are put back into the protective cover 2 through the power assembly to protect the monitoring head 5.

[0052] Working principle: By setting up a protective cover 2 and putting the support arm 4 and the monitoring head 5 into the protective cover 2, the monitoring head 5 is protected to prevent objects along the way from falling onto the top of the vehicle and damaging the monitoring head 5 during the vehicle's driving. When the vehicle reaches the target section, the drive shaft 3 is controlled to rotate by the power component in the vehicle body 1, and then the support arm 4 is rotated to the outside of the protective cover 2, so that the support arm 4 can extend outward, and the asphalt road surface is remotely sensed by the laser transmitter 6 and the laser receiver 7 on the monitoring head 5. When the monitoring work is completed, the support arm 4 and the monitoring head 5 are put back into the protective cover 2 through the power component; after the support arm 4 is put into the protective cover 2, a pair of sponges are driven by the motor 8 and the connecting rod assembly. The block 9 rotates, and then the end of the sponge block 9 rotates and rubs on the surface of the laser emitter 6 and the laser receiver 7, thereby wiping off the dirt on the surface of the laser emitter 6 and the laser receiver 7, avoiding the problem that too much dirt remains and affects the emission and reception of the laser; when the support arm 4 is retracted into the protective cover 2, the bottom of the support arm 4 will squeeze the elastic pad 17, and squeeze the air inside the elastic pad 17 into the air cavity 14 of the fixing ring 13 through the conduit 19, and then the air enters the sleeve 10 through the annular groove 15 and the through hole 16, pushing the extension rod 11 to slide outward, thereby pressing the sponge block 9 against the surface of the laser emitter 6 and the laser receiver 7, so that when the subsequent motor 8 drives the sponge block 9 to rotate through the sleeve 10 and the extension rod 11, the sponge can be improved. The squeezing force of the sponge block 9 on the laser emitter 6 and the laser receiver 7 is increased, thereby improving the efficiency of removing dirt; by setting the mounting groove 20 and the roller 21, the roller 21 can contact the surface of the vehicle body 1 and roll on the surface of the vehicle body 1 when the support arm 4 is retracted into the protective cover 2, which can provide a certain supporting effect on the support arm 4, and then the roller 21 rolls on the surface of the elastic pad 17, which can avoid the problem of the support arm 4 scratching the elastic pad 17; during the rotation of the sponge block 9, the water pipe 23 is turned on by the switch assembly, and then the water in the water tank 22 is poured onto the surface of the sponge block 9 through the water pipe 23, and then the sponge block 9 can further improve the efficiency of wiping dirt after absorbing water, and reduce the dirt on the surface of the laser emitter 6 and the laser receiver 7 The residue can also be reduced, and the friction and temperature can be avoided, so as to avoid the sponge block 9 from always being in dry friction with the laser transmitter 6 and the laser receiver 7, which may cause the sponge block 9 to be seriously worn. During the rotation of the sponge block 9, when one of the magnetic blocks 27 rotates to the upper position close to the water pipe 23, the magnetic block 27 will generate attraction to the sliding core 24, and pull the sliding core 24 downward by the magnetic attraction, so that the lower end of the Y-shaped hole 26 is exposed to the surface of the water pipe 23. At this time, the Y-shaped hole 26 is in a conducting state, and the water flow can flow downward through the Y-shaped hole 26. This operation enables the water pipe 23 to automatically spray water on the surface of the sponge block 9 when the sponge block 9 rotates, further improving the automation of the device, and the water flow is intermittent, which can effectively save water resources.By setting the elastic sheet 28, when the magnetic block 27 rotates to the upper side, it drives the sliding core 24 to move downward by magnetic attraction, at which time the magnetic block 27 collides with the sliding core 24 and causes the elastic sheet 28 to shake, and then the elastic sheet 28 drives the sponge block 9 to shake, thereby shaking off the impurities adsorbed inside the sponge block 9, avoiding the problem that a large amount of impurities enter the sponge block 9 and cause the cleaning effect of the sponge block 9 to deteriorate; by setting a plurality of arc grooves 29, if there are large particles of impurities on the surface of the laser emitter 6 and the laser receiver 7, the large particles of impurities can enter the arc groove 29 during the rotation and friction between the sponge block 9 and the laser emitter 6 and the laser receiver 7, and under the action of centrifugal force, the impurities are thrown out through the spiral arc groove 29, avoiding the problem that the impurities are always located between the sponge block 9 and the laser emitter 6 or the laser receiver 7, causing the impurities to scratch the surface of the laser emitter 6 and the laser receiver 7. ;
