Description

Technical Field

[0001] This utility model relates to the field of road quality testing technology, and in particular to a method for monitoring icing on asphalt pavement. Background Technology

[0002] An asphalt pavement icing monitoring system is a technical device that uses devices such as temperature monitors, infrared remote sensing equipment, and vibration components installed in icy sections such as bridges and tunnel entrances to collect real-time data on pavement temperature, humidity, and friction coefficient. After signal processing and analysis, the system provides early warnings of icing risks, offering decision-making support for traffic management and ensuring driving safety.

[0003] An asphalt pavement icing monitoring system uses a temperature monitor to sense the pavement temperature in real time. When the pavement approaches freezing point, it combines data from a humidity sensor to determine whether icing conditions have been met. Alternatively, it utilizes infrared remote sensing technology to detect changes in the pavement temperature field, measures the pavement friction coefficient and ice thickness using contact sensors, and analyzes vibration wave reflection differences using a vibration component to determine the ice layer condition. The monitoring data is then transmitted to a control component via a data processing module, triggering an early warning device and linking it to de-icing equipment. Its application scenarios cover icy road sections such as highway bridges, tunnel entrances and exits, sharp bends in urban roads, and airport runways. It can provide traffic management departments with real-time pavement condition information to assist in decision-making, ensure driving safety, and reduce the risk of traffic accidents caused by pavement icing.

[0004] In existing technologies, under the influence of high-frequency vehicle traffic, environmental vibration, or extreme weather, the sensors of the equipment may shift position or make poor contact due to continuous vibration, resulting in deviations in the acquisition of data such as temperature and humidity. This leads to a decrease in the accuracy of icing warnings. Severe vibration can also cause internal electronic components to loosen or even be damaged, shortening the service life of the equipment and increasing maintenance costs. Therefore, an asphalt pavement icing monitoring method is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1 to 3This utility model provides an embodiment of an asphalt pavement icing monitoring system, comprising a sensor 1. The sensor 1 provides installation space and stability for subsequent components. A fixing ring 2 is fixedly connected to the outer wall of the sensor 1, providing a stable installation base for the fixing ring 2. Simultaneously, the sensor 1 serves as a connecting component, connecting the sensor 1 to components such as springs 3 above. Multiple springs 3 are fixedly connected to the top of each fixing ring 2, with the top of the springs 3 fixed to the fixing ring 2. The springs 3 serve as buffers and force transmission components. The other ends of the three springs 3 are fixedly connected to a force-bearing plate 4. The deformation pressure of the pavement acts on the force-bearing plate 4, causing it to move downwards and compress the springs 3, thus buffering the downward pressure.

[0032] Multiple connecting plates 5 are fixedly connected to the bottom end of the force-bearing plate 4. The connecting plates 5 are fixed to the bottom end of the force-bearing plate 4. The force-bearing plate 4 transmits the force generated by the change of road surface to the connecting plates 5, which drives the supporting rods 6, supporting columns 8 and other components connected to it below to move. The inner walls of the multiple connecting plates 5 are rotatably connected to the supporting rods 6. The supporting rods 6 are rotatably connected to the inner walls of the connecting plates 5. When the connecting plates 5 are moved by force, the supporting rods 6 can rotate around the connection point. The other ends of the multiple supporting rods 6 are rotatably connected to the sliders 7. The sliders 7 are rotatably connected to the other ends of the supporting rods 6. The rotation of the supporting rods 6 drives the sliders 7 to slide on the preset track. Multiple supporting columns 8 are fixedly connected to the bottom end of the force-bearing plate 4. The supporting columns 8 are fixed to the bottom end of the force-bearing plate 4 and play the role of supporting and stabilizing the entire monitoring structure. The outer walls of the multiple supporting columns 8 are fixedly connected to the fixing blocks 9. The fixing blocks 9 are fixed to the outer walls of the supporting columns 8 and are used to fix the position of the supporting columns 8 so that they remain stable during the force process and avoid displacement or shaking.

[0033] Reference Figures 2 to 4 A top cover 10 is slidably connected to the inner wall of sensor 1, providing a movable closed end for easy installation and maintenance of internal components. A first electrode plate 11 is fixedly connected to the inner wall of the top cover 10, and the sliding of the top cover 10 directly drives the first electrode plate 11 to move. A second electrode plate 12 is fixedly connected to the inner wall of sensor 1, serving as a fixed electrode plate for capacitive detection. Together with the movable first electrode plate 11, it forms a capacitive detection structure. Two sealing rings 13 are fixedly connected to the inner wall of sensor 1, preventing external moisture, dust, and other impurities from entering the interior of sensor 1 and protecting precision components such as the first electrode plate 11 and the second electrode plate 12 from contamination. Sealing rings 14 are fixedly connected to both the upper and lower ends of the first electrode plate 11, further enhancing the sealing between the first electrode plate 11 and the inner wall of sensor 1.

[0034] A temperature monitor 15 is fixedly connected to the top of electrode plate 12. The temperature monitor 15 is fixed to the top of electrode plate 12 to monitor the temperature changes inside sensor 1 in real time, compensate for the influence of temperature on capacitance detection, improve the accuracy of icing detection, and reduce misjudgments caused by temperature interference. Multiple threaded rods 16 are fixedly connected to the inner wall of sensor 1. These threaded rods 16 are fixed to the inner wall of sensor 1 for fixing other internal components or connecting to external structures, providing stable mechanical support, and ensuring the stability of the internal structure of sensor 1. An ambient temperature and humidity port 17 is fixedly connected to the outer wall of sensor 1, allowing ambient temperature and humidity to enter the sensor 1. This, in conjunction with the temperature monitor 18, monitors changes in ambient temperature and humidity in real time. The rear end of the ambient temperature and humidity port 17 is fixedly connected to the temperature monitor 18. 8. Temperature monitor 18 is fixed at the rear end of ambient temperature and humidity port 17. It is specifically used to detect the external ambient temperature. Combined with the data from temperature monitor 15, it comprehensively analyzes the temperature difference between the inside and outside. An aviation connector 19 is fixedly connected to the left outer wall of electrode plate 11. The aviation connector 19 is fixed to the left outer wall of electrode plate 11 and serves as a data transmission interface between sensor 1 and external devices. It transmits the detected capacitance changes, temperature and other data to the external control components to realize the output of monitoring data and remote monitoring. A threaded rod 20 is threadedly connected to the bottom end of sensor 1. The threaded rod 20 is threadedly connected to the bottom end of sensor 1 and is used to install the bottom cover 21, providing a detachable connection method. The bottom cover 21 is fixedly connected to the outer wall of threaded rod 20. The bottom cover 21 is fixed to the outer wall of threaded rod 20, sealing the bottom end of sensor 1 and protecting the internal components from external physical impact and contamination.

[0035] The outer wall of the bottom cover 21 is slidably connected to three set screws 22. Tightening the set screws 22 secures the bottom cover 21 to the bottom of the sensor 1. The outer wall of the slider 7 is slidably connected to the inner wall of the fixing ring 2. The fixing ring 2 provides a sliding track and support for the slider 7. The outer wall of the support column 8 is slidably connected to the inner wall of the fixing ring 2. The fixing ring 2 guides and limits the support column 8. The inner wall of the spring 3 is sleeved on the outer wall of the support column 8. The support column 8 provides support and guidance for the spring 3, preventing it from bending or shifting during compression and extension.

[0036] Working principle: When the force plate 4 is pressed down, it moves downward, compressing the multiple springs 3 fixed at the top of the fixing ring 2. The springs 3 undergo elastic deformation during compression, buffering the downward pressure. Simultaneously, the force plate 4 drives the connecting plate 5 fixed at the bottom to move downward. The support rod 6 rotatably connected to the inner wall of the connecting plate 5 rotates accordingly. When the support rod 6 moves about the rotation connection point as an axis, it pushes the slider 7 connected at the other end to slide on the track opened on the outer wall of the fixing ring 2. The support column 8 fixed at the bottom of the force plate 4 provides support and guidance for the force plate 4 during the force application process, ensuring that there is no shaking that would affect the operation of the sensor 1.

[0037] During the stress process, the fixing block 9 provides a limiting effect for the support column 8, maintaining the stability during operation. The support column 8 plays a role in stabilizing the entire structure, preventing tilting or displacement due to stress from affecting the monitoring accuracy. The elastic buffer structure effectively absorbs the impact energy from vehicle crushing, environmental vibration, or strong winds, preventing the sensor 1 from shifting position or making poor contact due to severe vibration. This ensures the stability and accuracy of data collection such as temperature, humidity, and friction coefficient, and improves the reliability of icing warnings. Equipment damaged by vibration requires frequent maintenance or replacement, while the vibration damping device can reduce the failure rate and the number of times maintenance personnel need to go out. Its advantages are even more obvious in scenarios where maintenance is inconvenient, such as low temperatures in winter and icy roads.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
