[0003] In the existing technology, the compaction effect of the roadbed and pavement is usually evaluated by measuring and collecting the rolling temperature and rolling compaction data, but the accuracy is about 5m, and it is impossible to truly and effectively measure the paving speed, rolling temperature, rolling compaction speed and other information. In addition, it is impossible to monitor the actual road conditions of the uneven road surface, and it is inconvenient to control the paving amount when paving asphalt. Summary of the Invention

[0004] Based on the technical problem that the existing monitoring system cannot monitor the unevenness of the road surface, the present invention proposes a roadbed and road surface compaction intelligent paving monitoring system and a monitoring method thereof.

[0006] The construction site of the paver is provided with a monitoring device, the paver is provided with a high-precision positioning device, and the construction site of the paver is provided with a positioning base station, and the speed and number of passes of the on-site paver are measured through the differential signal of the positioning base station.

[0007] Preferably, the camera is fixedly mounted on the front end of the paver, the infrared thermal imager is arranged inside the camera, a fixed bearing is fixedly mounted on the outer surface of the suspension frame, the two fixed bearings are symmetrically distributed with the axis of the paver as the symmetry center, and a rotating rod is fixedly mounted on the inner shaft of each of the two fixed bearings;

[0008] Through the above technical solution, the camera monitors the road surface. When an obstacle appears on the road surface, the infrared thermal imager can detect the temperature of the obstacle and determine whether the obstacle is a living thing so as to make different adjustments to the paver. The infrared thermal imager uses an infrared detector and an optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector, thereby obtaining an infrared thermal image. This thermal image corresponds to the heat distribution field on the surface of the object.

[0009] Preferably, a rotating disk is fixedly mounted on the front end of the rotating rod, the outer surface of the rotating disk is fixedly connected to the rotating rod, the swing rod is fixedly connected to the outer surface of the rotating rod, the swing rod performs a circular motion with the rotating rod as the center, and a collar is fixedly mounted on the front end of the swing rod;

[0010] Through the above technical solution, when the swing arm makes a circular motion with the rotating rod as the center, the swing arm will drive the rotating rod to rotate, thereby rotating the rotating disk. The rotating rod can rotate stably in the fixed bearing, ensuring that the rotating disk can maintain stable rotation.

[0011] Preferably, the interior of the collar is rotatably connected to a connecting column, the inner ring of the roller is fixedly connected to one end of the connecting column, a hydraulic cylinder is fixedly installed on the other end of the connecting column, a connecting round rod is fixedly connected between the two hydraulic cylinders, the outer surface of the connecting round rod is rotatably connected to a rotating ring, and the outer surface of the rotating ring is fixedly connected to a measuring rod;

[0012] Through the above technical solution, the roller rolls along the ground, and when encountering an uneven road surface, the connecting column will change its position. The ring can rotate freely outside the connecting column, thereby allowing the swing of the swing arm to be unimpeded. When the hydraulic cylinder is started, it can drive the connecting column to move, thereby adjusting the distance between the two rollers.

[0013] Preferably, one end of the measuring rod is fixedly connected to an angle sensor, a connecting rod is fixedly installed on the outer surface of the angle sensor, a fixed round rod is fixedly installed on the outer surface of the suspension bracket, and a connecting ring is fixedly connected to the front end of the connecting rod, and the connecting ring is rotatably connected to the outer surface of the fixed round rod.

[0014] Through the above technical solution, when the road surface is tilted in the width direction, there will be a height difference between the two rollers, causing the connecting round rod in the middle to tilt. At this time, the rotating ring will drive the measuring rod to rotate, and the angle sensor can then measure the deflection angle of the measuring rod to know the degree of inclination of the road surface.

[0015] Preferably, the other two angle sensors are fixedly connected to the outer surfaces of the two rotating rods respectively, the outer surfaces of the two rotating disks are fixedly connected to torsion springs respectively, and the torsion springs are fixedly installed on the outer surface of the suspension bracket.

[0016] Through the above technical solution, the angle sensor on the rotating rod can measure the rotation angle of the rotating rod, and then measure the swing angle of the swing arm, while the torsion of the torsion spring can ensure that the roller can always keep close to the ground.

[0017] Preferably, a U-shaped rod is fixedly installed on the outer surface of the hydraulic cylinder, a connecting ring is rotatably connected to the outer surface of the U-shaped rod, a pull rope is fixedly connected to the outer surface of the connecting ring, a driving motor is fixedly installed on the outer surface of the suspension frame, a winding rod is fixedly connected to the rotating shaft of the driving motor, one end of the pull rope is fixedly connected to the outer surface of the winding rod, and the pull rope is wrapped around the outer surface of the winding rod.

[0018] Through the above technical solution, when the drive motor is started, the rotating shaft drives the winding rod to rotate and wind the pull rope, and then the pull rope pulls the U-shaped rod to make the roller leave the ground, making it convenient to use the hydraulic cylinder to adjust the distance between the two rollers.

[0019] Preferably, the monitoring device includes a satellite, a GPS base station, a monitoring center, a database, a server, and a wireless communication antenna; the high-precision positioning device on the paver transmits an electrical signal to the wireless communication antenna via wireless transmission; the server is electrically connected to the wireless communication antenna and the monitoring center via wires; the wireless communication antenna transmits the electrical signal to the server; the server transmits the electrical signal to the monitoring center via wired transmission; and the server transmits the electrical signal to the database via wireless transmission;

[0020] Through the above technical solution, in order to achieve barrier-free connection between "people, machines, and scenes" throughout the entire operation process, satellites, GPS base stations, monitoring centers, databases, servers, and wireless communication antennas are used to remotely monitor and control the paver.

[0021] Preferably, the high-precision positioning device on the paver, the satellite and the GPS reference station all transmit electrical signals to each other through wireless transmission. The satellite locates the position of the paver through the electrical signals transmitted by the high-precision positioning device, and the GPS reference station can perform auxiliary positioning.

[0022] Through the above technical solution, in order to facilitate the remote positioning of the paver, wireless transmission is used to transmit electrical signals between high-precision positioning equipment, satellites and GPS base stations. The high-precision positioning equipment uses GNSS high-precision positioning equipment provided by Shanghai Huace Navigation, using Beidou second-generation + GNSS dual-Samsung eight-frequency GNSS board.

[0023] Preferably, a monitoring method for a roadbed and pavement compaction intelligent paving monitoring system is provided, and the specific monitoring method is as follows:

[0024] Step 1: When the paver spreads asphalt on the road surface, it is necessary to monitor the specific conditions of the road surface. During monitoring, the paver travels on the road surface, driving the roller to travel on the road surface. When the roller encounters an uneven section on the road surface, the roller will roll over the raised surface on the road surface or sink into the groove on the road surface. At this time, the roller will drive the connecting column to move, and the collar will rotate outside the connecting column, thereby driving the front end of the swing arm, so that the tail end of the swing arm drives the rotating rod to rotate. When the rotating rod rotates, the angle sensor can detect the angle of rotation, and then determine the shape of the raised or sunken road section. When the road surface tilts in the width direction, the connecting round rod drives the rotating ring, and the rotating ring drives the measuring rod to rotate. The angle sensor connected to the measuring rod can measure the angle of rotation, and then measure the inclination.

[0025] Step 2: Since the width of the paved road surface may sometimes be different, the distance between the two rollers needs to be adjusted. At this time, the motor is started, the shaft drives the winding rod to rotate, the pull rope is wound so that the pull rope pulls the U-shaped rod, driving the hydraulic cylinder to move, allowing the roller to leave the ground, and then starting the hydraulic cylinder to drive the roller to move horizontally, thereby adjusting the roller distance.

[0026] Step three: Determine the obstacles on the road. The camera will take pictures of the obstacles on the road. If an obstacle is photographed, the paver will be controlled to stop. The infrared thermal imager in the camera will detect the temperature of the obstacle to determine whether the obstacle is alive. If it is alive, the remote control will sound the horn to scare it away. If it is dead, the on-site staff will move it away.

[0027] Step 4: Remote positioning. The high-precision positioning device on the paver transmits electrical signals to the satellite, and the GPS base station can perform positioning. The monitoring center receives the electrical signals from the high-precision positioning device through the wireless communication antenna and server, and then remotely monitors the paver. The database saves the data transmitted by the server.

[0028] The beneficial effects of the present invention are:

[0029] 1. By setting up a detection device, the paver drives the roller on the road surface. When the roller encounters an uneven section on the road surface, the roller will roll over the raised surface or sink into the groove of the road surface. At this time, the roller will drive the connecting column to move, and the collar can rotate freely outside the connecting column, thereby driving the front end of the swing arm without hindrance, so that the tail end of the swing arm drives the rotating rod to rotate. When the rotating rod rotates, the angle sensor can measure the rotation angle. The diameter of the swing arm can be measured in advance. Based on the rotation angle, the distance rolled by the roller can be calculated, and then the length of the raised or recessed road section can be determined, which is convenient for controlling the asphalt paving speed. On raised sections, less asphalt is paved, and on recessed sections, more asphalt is paved. When the road surface tilts in the width direction, the connecting rod drives the rotating ring, which drives the measuring rod to rotate. The angle sensor connected to the measuring rod can measure the rotation angle and then measure the inclination angle, achieving the effect of conveniently monitoring the specific unevenness of the road surface.

[0030] 2. By setting up a monitoring device, in order to achieve remote positioning, the high-precision positioning equipment on the paver can transmit electrical signals to the satellite, the GPS base station can perform auxiliary positioning, and the monitoring center can receive the electrical signals of the high-precision positioning equipment through the wireless communication antenna and the server, and then remotely monitor the paver. The database can save the data transmitted by the server, achieving the effect of facilitating remote monitoring of the paver.

[0031] 3. By setting up an infrared thermal imager, when the camera captures an obstacle, the front and back images will deteriorate in a short period of time, which can cause the monitoring center to issue an alarm and temporarily stop the paver. At this time, the infrared thermal imager can detect the temperature of the obstacle. If it is a living thing, the horn can be remotely controlled to sound to scare it away, reducing the trouble for the staff. If it is a dead object, the on-site staff can move it away, achieving the effect of reducing the trouble for the staff and facilitating monitoring. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] Example 1

[0044] Reference Figures 1-9A roadbed and pavement compaction intelligent paving monitoring system includes a paver 1, a detection device is provided at the front end of the paver 1, a suspension frame 101 is provided at the front end of the paver 1, and the suspension frame 101 is slidably connected to the front end mounting plate of the paver 1 through a card plate on the outer surface. The detection device includes a camera 2 for monitoring the road surface, a roller 3 for sensing the unevenness of the road surface, an infrared thermal imager 4 for judging whether the road obstacle is a living object, a swing arm 5 and an angle sensor 6 for detecting the change in the horizontal inclination angle of the swing arm 5. The camera 2 monitors the ground and the infrared thermal imager 4 senses the temperature of the road obstacle. When the roller 3 rolls along the ground and encounters uneven ground, it drives the swing arm 5 to deflect with the tail end of the swing arm 5 as the center. The deflection angle is then detected by the angle sensor 6 and transmitted to the monitoring system.

[0045] A monitoring device is provided at the construction site of the paver 1. A high-precision positioning device 7 is provided on the paver 1. A positioning base station 8 is provided at the construction site of the paver 1. The speed of the paver 1 is measured by the differential signal of the positioning base station 8.

[0046] By setting up the infrared thermal imager 4, after the camera 2 captures an obstacle, the front and back images will deteriorate in a short period of time, which can enable the monitoring center 111 to issue an alarm and temporarily stop the paver 1. At this time, the infrared thermal imager 4 can detect the temperature of the obstacle. If it is a living thing, the horn can be remotely controlled to sound to scare the living thing away, reducing the trouble of the staff. If it is a dead object, the on-site staff can move it away, achieving the effect of reducing the trouble of the staff and facilitating monitoring.

[0047] To facilitate determining whether road obstacles are living things, camera 2 is fixedly mounted on the front end of paver 1, and infrared thermal imager 4 is located on the internal housing of camera 2. The two are electrically connected via wires for use. Infrared thermal imager 4 is used for thermal imaging, while camera 2 acts as an eye, monitoring the front view and facilitating backstage control. Fixed bearings 11 are fixedly mounted on the outer surface of suspension bracket 101. The two fixed bearings 11 are symmetrically distributed around the axis of paver 1. Rotating rods 12 are fixedly mounted on the inner shafts of both fixed bearings 11. Camera 2 monitors the road surface. When an obstacle appears on the road surface, infrared thermal imager 4 can detect the temperature of the obstacle to determine whether it is living, so that different adjustments can be made to paver 1.

[0048] In order to ensure that the rotating disk 13 can maintain stable rotation, the rotating disk 13 is fixedly installed at the front end of the rotating rod 12, and the outer surface of the rotating disk 13 is fixedly connected to the rotating rod 14. The swing rod 5 is fixedly connected to the outer surface of the rotating rod 14. The swing rod 5 performs circular motion with the rotating rod 14 as the center. A ring 51 is fixedly installed at the front end of the swing rod 5. When the swing rod 5 performs circular motion with the rotating rod 14 as the center, the swing rod 5 will drive the rotating rod 14 to rotate, and then the rotating disk 13 rotates. The rotating rod 12 can rotate stably in the fixed bearing 11, ensuring that the rotating disk 13 can maintain stable rotation.

[0049] In order to facilitate the use of the hydraulic cylinder 53 to adjust the distance between the two rollers 3, the internal rotation of the ring 51 is connected to the connecting column 52, the inner ring of the roller 3 is fixedly connected to one end of the connecting column 52, and the other end of the connecting column 52 is fixedly installed with the hydraulic cylinder 53. A connecting round rod 54 is fixedly connected between the two hydraulic cylinders 53, and the outer surface of the connecting round rod 54 is rotatably connected to a rotating ring 55, and the outer surface of the rotating ring 55 is fixedly connected to a measuring rod 56. The roller 3 rolls along the ground, and encountering an uneven road surface will cause the connecting column 52 to change position. The ring 51 can rotate freely outside the connecting column 52, thereby allowing the swing of the swing arm 5 to be unimpeded. When the hydraulic cylinder 53 is started, it can drive the connecting column 52 to move, thereby adjusting the distance between the two rollers 3.

[0050] In order to facilitate the measurement of the inclination of the road surface, one end of the measuring rod 56 is fixedly connected to an angle sensor 6, and a connecting rod 61 is fixedly installed on the outer surface of the angle sensor 6. The outer surface of the suspension frame 101 is fixedly installed with a fixed round rod 15. The front end of the connecting rod 61 is fixedly connected to a connecting ring 62, and the connecting ring 62 is rotatably connected to the outer surface of the fixed round rod 15. When the width direction of the road surface is tilted, there will be a height difference between the two rollers 3, allowing the connecting round rod 54 in the middle to tilt. At this time, the rotating ring 55 will drive the measuring rod 56 to rotate, and the angle sensor 6 can then measure the deflection angle of the measuring rod 56, thereby knowing the inclination of the road surface.

[0051] In order to ensure that the roller 3 can always be in close contact with the ground, the other two angle sensors 6 are respectively fixedly connected to the outer surfaces of the two rotating rods 14, and the outer surfaces of the two rotating disks 13 are respectively fixedly connected with torsion springs 16, which are fixedly installed on the outer surface of the suspension bracket 101. The angle sensor 6 on the rotating rod 14 can measure the rotation angle of the rotating rod 14, and then measure the swing angle of the swing rod 5, and the torsion force of the torsion spring 16 can ensure that the roller 3 can always be in close contact with the ground.

[0052] In order to facilitate the use of the hydraulic cylinder 53 to adjust the distance between the two rollers 3, a U-shaped rod 57 is fixedly installed on the outer surface of the hydraulic cylinder 53, and the outer surface of the U-shaped rod 57 is rotatably connected to a connecting ring 58, and the outer surface of the connecting ring 58 is fixedly connected to a pull rope 59. The outer surface of the suspension frame 101 is fixedly installed with a drive motor 17, and a rolling rod 18 is fixedly connected to the rotating shaft of the drive motor 17. One end of the pull rope 59 is fixedly connected to the outer surface of the rolling rod 18, and the pull rope 59 is wound around the outer surface of the rolling rod 18. When the drive motor 17 is started, the rotating shaft drives the rolling rod 18 to rotate to roll the pull rope 59, and then the pull rope 59 pulls the U-shaped rod 57 to lift the roller 3 off the ground, making it convenient to use the hydraulic cylinder 53 to adjust the distance between the two rollers 3.

[0053] In order to facilitate remote monitoring and control of the paver 1, the monitoring device includes a satellite 19, a GPS base station 110, a monitoring center 111, a database 112, a server 113 and a wireless communication antenna 114. The high-precision positioning device 7 on the paver 1 transmits the electrical signal to the wireless communication antenna 114 through wireless transmission. The server 113 is electrically connected to the wireless communication antenna 114 and the monitoring center 111 through wires. The wireless communication antenna 114 transmits the electrical signal to the server 113, and the server 113 transmits the electrical signal to the monitoring center 111 through wired transmission. The server 113 transmits the electrical signal to the database 112 through wireless transmission. In order to achieve barrier-free connection between "people, machines, and scenes" throughout the operation process, the paver 1 is remotely monitored and controlled using satellite 19, GPS base station 110, monitoring center 111, database 112, server 113 and wireless communication antenna 114.

[0054] In order to facilitate the remote positioning of the paver 1, the high-precision positioning device 7, satellite 19 and GPS base station 110 on the paver 1 transmit electrical signals to each other through wireless transmission. The satellite 19 locates the position of the paver 1 through the electrical signal transmitted by the high-precision positioning device 7, and the GPS base station 110 can perform auxiliary positioning. In order to facilitate the remote positioning of the paver 1, wireless transmission is used to transmit electrical signals between the high-precision positioning device 7, satellite 19 and GPS base station 110.

[0055] By setting up the detection device, the paver 1 drives the roller 3 to drive on the road surface. When the roller 3 encounters an uneven section on the road surface, the roller 3 will roll over the raised surface on the road surface or sink into the groove of the road surface. At this time, the roller 3 will drive the connecting column 52 to move, and the collar 51 can rotate freely outside the connecting column 52, thereby driving the front end of the swing rod 5 without hindrance, so that the tail end of the swing rod 5 drives the rotating rod 14 to rotate. When the rotating rod 14 rotates, the angle sensor 6 can measure the angle of rotation, and the diameter of the swing rod 5 can be measured in advance. The distance rolled by the roller 3 can be measured, and then the length of the raised or sunken section of the road surface can be calculated according to the rotation angle, so as to determine the length of the asphalt paving speed. The raised section controls the asphalt paving to be less, and the sunken section controls the asphalt paving to be more. When the road surface tilts in the width direction, the connecting rod 54 drives the rotating ring 55, and the rotating ring 55 drives the measuring rod 56 to rotate. The angle sensor 6 connected to the measuring rod 56 can measure the rotation angle, and then measure the inclination angle, so as to achieve the effect of conveniently monitoring the specific concave and convex conditions of the road surface.

[0056] By setting up a monitoring device, in order to achieve remote positioning, the high-precision positioning device 7 on the paver can transmit electrical signals to the satellite 19, the GPS base station 110 can perform auxiliary positioning, and the monitoring center 111 can receive the electrical signals of the high-precision positioning device 7 through the wireless communication antenna 114 and the server 113, and then remotely monitor the paver 1, and the database 112 can save the data transmitted by the server 113, thereby achieving the effect of facilitating remote monitoring of the paver 1.

[0057] Example 2

[0058] Reference Figures 1-9 , a monitoring method for a roadbed and pavement compaction intelligent paving monitoring system, the specific monitoring method is:

[0059] Step 1: When the paver 1 spreads asphalt on the road surface, it is necessary to monitor the specific conditions of the road surface, such as Figure 4-Figure 8 As shown, during monitoring, the paver 1 is traveling on the road surface, driving the roller 3 to travel on the road surface. When the roller 3 encounters an uneven section on the road surface, the roller 3 will roll over the raised surface on the road surface or sink into the groove on the road surface. At this time, the roller 3 will drive the connecting column 52 to move, and the collar 51 will rotate outside the connecting column 52, thereby driving the front end of the swing rod 5, so that the tail end of the swing rod 5 drives the rotating rod 14 to rotate. When the rotating rod 14 rotates, the angle sensor 6 can detect the rotation angle, and then determine the shape of the raised or sunken road section. Then, as shown in FIG. Figure 9As shown, when the road surface tilts in the width direction or encounters a small obstacle, there is no need to move the obstacle. At this time, the positions of the two rollers 3 will tilt, and the connecting rod 54 drives the rotating ring 55, which drives the measuring rod 56 to rotate. The angle sensor 6 connected to the measuring rod 56 can measure the rotation angle and thus the inclination angle.

[0060] Step 2: Since the width of the paved road surface may vary, the distance between the two rollers 3 needs to be adjusted. At this time, the motor is started, and the shaft drives the winding rod 18 to rotate. The pull rope 59 is wound so that the pull rope 59 pulls the U-shaped rod 57, driving the hydraulic cylinder 53 to move, allowing the rollers 3 to leave the ground. The hydraulic cylinder 53 is then started to drive the rollers 3 to move horizontally, thereby adjusting the distance between the rollers 3.

[0061] Step 3: Obstacles on the road are identified. Camera 2 captures the obstacle and stops the paver 1 if it is detected. The infrared thermal imager 4 in camera 2 detects the temperature of the obstacle to determine whether it is alive. If it is alive, the horn is sounded remotely to scare it away. If it is dead, the on-site staff is asked to move it away.

[0062] Step four, remote positioning, the high-precision positioning device 7 on the paver transmits the electrical signal to the satellite 19, the GPS base station 110 can perform positioning, and the monitoring center 111 receives the electrical signal of the high-precision positioning device 7 through the wireless communication antenna 114 and the server 113, and then remotely monitors the paver 1, and the database 112 saves the data transmitted by the server 113.

[0063] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.

8. A monitoring method for a roadbed and pavement compaction intelligent paving monitoring system according to any one of claims 1 to 7, wherein the monitoring method comprises: Step 1: When the paver (1) spreads asphalt on the road surface, it is necessary to monitor the specific conditions of the road surface. During the monitoring, the paver (1) travels on the road surface, driving the roller (3) to travel on the road surface. When the roller (3) encounters an uneven section on the road surface, the roller (3) will roll over the raised surface on the road surface or sink into the groove of the road surface. At this time, the roller (3) will drive the connecting column (52) to move, and the ring (51) will rotate outside the connecting column (52), thereby driving the front end of the swing rod (5) to move. , so that the tail end of the swing rod (5) drives the rotating rod (14) to rotate, and when the rotating rod (14) rotates, the angle sensor (6) can detect the angle of rotation, and then determine the shape of the road section of the convex or concave road surface; when the road surface is tilted in the width direction, the connecting rod (54) drives the rotating ring (55), and the rotating ring (55) drives the measuring rod (56) to rotate, and the angle sensor (6) connected to the measuring rod (56) can measure the angle of rotation, and then measure the inclination angle; Step 2: Since the width of the paved road surface may sometimes be different, it is necessary to adjust the distance between the two rollers (3). At this time, the motor is started, the rotating shaft drives the rolling rod (18) to rotate, the pull rope (59) is wound so that the pull rope (59) pulls the U-shaped rod (57), drives the hydraulic cylinder (53) to move, and allows the rollers (3) to leave the ground. Then, the hydraulic cylinder (53) is started to drive the rollers (3) to move horizontally, thereby adjusting the distance between the rollers (3); Step 3: Determine the obstacles on the road surface. The camera (2) takes a photo of the obstacles on the road surface. If an obstacle is photographed, the paver (1) is controlled to stop. The infrared thermal imager (4) in the camera (2) detects the temperature of the obstacle to determine whether the obstacle is alive. If it is alive, the horn is sounded remotely to scare the living thing away. If it is dead, the on-site staff is asked to move it away. Step 4: remote positioning. The high-precision positioning device (7) on the paver transmits an electrical signal to the satellite (19). The GPS base station (110) is able to perform positioning. The monitoring center (111) receives the electrical signal from the high-precision positioning device (7) through the wireless communication antenna (114) and the server (113), and then remotely monitors the paver (1). The database (112) stores the data transmitted by the server (113).
