[0030] Embodiment 1

[0031] Referring to Figure 1 The utility model embodiment provides a kind of road surface icing detection device, its main function is to monitor whether the road surface appears icing phenomenon and the degree of icing in real time, to provide important driving safety reference information for driver, ensure that vehicle can safely travel under adverse weather conditions.

[0032] Referring to Figure 1 In the embodiment, a road surface icing detection device includes a mounting rod 200, the mounting rod 200 is arranged on one side of the detected road surface 100. A icing detector 300 is provided on the mounting rod 200, and the icing detector 300 is fixedly installed on the mounting rod 200. The icing detector 300 is arranged at a higher position through the mounting rod 200, and such arrangement enables the icing detector 300 to effectively cover or cover the detected road surface 100 area within the expected range, so that the icing detector 300 can detect the icing degree within the expected range.

[0033] Referring to Figure 1 And Figure 5 In the embodiment, a certain interval distance is maintained between the icing detector 300 and the road surface 100; such arrangement can avoid the detector directly contacting the road surface 100, thereby reducing the damage to the detector itself caused by the change of the road surface 100 condition. The icing detection device includes a mounting cylinder 310, and a control circuit 311 and a detection component 320 arranged in the mounting cylinder 310. The detection component 320 is a component for real-time monitoring of the road surface 100 condition by using remote sensing technology. It adopts a non-contact detection mode, transmits detection light 400 and receives the spectral information reflected by the road surface 100, to realize accurate measurement of the road surface 100 state (such as icing, snow, water and its thickness). This detection method not only improves the detection accuracy, but also effectively avoids additional damage to the road surface 100 since it is non-contact, and at the same time ensures the safety and stable operation of the detection equipment itself.

[0034] Referring to Figure 5In this embodiment, the working principle of the detection component 320 is mainly based on spectral analysis technology. The detection component 320 is built-in with an emission light source (emission unit 321) that can emit monochromatic light rays (detection light rays 400) of a single wavelength, which are accurately irradiated onto the road surface 100 after focusing by a lens. Due to the differences in the material and state of different road surfaces 100, the reflected light rays will also show corresponding differences in intensity and spectral characteristics. The spectral receiving device in the sensor of the detection component 320 has accurate measurement capability and can accurately measure the intensity and wavelength of the reflected light. Subsequently, these spectral data will be analyzed and calculated by the internal processing unit. Finally, the analysis results about the condition of the road surface 100 can be output, including but not limited to the dry, wet, icy, etc. state of the road surface 100. The application range of the detection component 320 is very wide, which is suitable for various traffic scenes such as highways, urban roads, airport runways, bridges and tunnels, etc., and provides effective road surface 100 condition monitoring and early warning for these scenes.

[0035] Please refer to Figure 4 and Figure 5 , the detection component 320 is set as two main parts, namely the emission unit 321 and the receiving unit 322. Both units are connected with the control circuit 311 in circuit to ensure their cooperative work. In addition, the above-mentioned sensor is also configured on the control circuit 311 to facilitate the control of the detection process and data processing. The main function of the emission unit 321 is to emit specific monochromatic light rays, which play a crucial role in the detection process. The receiving unit 322 is responsible for capturing the monochromatic light rays reflected from the detected surface, and by analyzing the characteristics of these reflected light rays, the condition of the detected surface can be evaluated and judged.

[0036] Please refer to Figure 4Inside the installation cylinder 310, in addition to other components, a shooting unit 312 is installed; while the transmitting unit 321 and the receiving unit 322 are scattered on the left and right sides of the shooting unit 312. This unique layout arrangement makes the transmitting unit 321 and the receiving unit 322 can be effectively scattered, so that when the road surface 100 is detected, the detection light 400 emitted by the transmitting unit 321 can cover the measured road surface 100, without causing any obstruction to the line of sight of the shooting unit 312. Such a setting ensures that optical detection and image acquisition can work together without interfering with each other. On the one hand, through the close cooperation of the transmitting unit 321 and the receiving unit 322, the reflection characteristics of the detection light 400 can be used to accurately identify whether the road surface 100 is icy; on the other hand, the shooting unit 312 can capture and record the image information of the road surface 100 in real time, providing intuitive visual feedback to the operator. This comprehensive judgment and multi-dimensional analysis method not only enables accurate assessment of the icing condition of the road surface 100, but also greatly improves the accuracy and reliability of the detection.

[0037] Please refer to Figure 2 and Figure 4 , the installation cylinder 310 is provided with a protective lens for protecting the detection component 320 and the shooting unit 312 at one end where the shooting unit 312 is arranged, and the protective lens is limited inside the installation cylinder 310. The inner wall of the installation cylinder 310 is also provided with uniformly distributed heating wires 313 for protecting the operation of the internal components of the installation cylinder 310 from the influence of temperature. Through such a setting, the protective lens is added at one end of the shooting unit 312 of the installation cylinder 310, effectively preventing dust, rain and snow and other external environments from damaging the detection component 320 and the shooting unit 312, ensuring the cleanliness and stability of the equipment, prolonging the service life of the components and enhancing the environmental adaptability of the components; at the same time, the uniformly distributed heating wires 313 in the inner wall of the installation cylinder 310 can avoid the influence of low temperature environment on the internal components, and also prevent the problem of detection light 400 obstruction or lens blur caused by frosting or icing, so as to ensure that the device can still work normally under extreme weather conditions, and improve the environmental adaptability and service life of the equipment.

[0038] Further, laser detection technology is a quite common and widely used icing detection technology. In this embodiment, the icing detection principle adopted by the icing detector 300 can also refer to the detection principle adopted by the OP RW-15005 type laser scanning road surface icing detector produced by the Japanese takuwa company. This detector can accurately detect whether the road surface is icy by emitting a laser beam and receiving the reflected signal, thereby providing effective monitoring for road safety.

[0039] Please refer toFigure 2 And Figure 3 The icing detector 300 is connected with the mounting rod 200 through an adjustable connecting frame; the mounting rod 200 comprises a first connecting part 330, a second connecting part 340 and a third connecting part 350, which together realize the adjustment of the detection angle of the icing detector 300, so as to cover the detection range of different angles. The first connecting part 330 and the third connecting part 350 are respectively arranged at both ends of the second connecting part 340 as intermediate parts to connect both ends.

[0040] Further, please refer to Figure 2 And Figure 3 The mounting cylinder 310 is fixedly connected with one end of the first connecting part 330, and the top of the mounting cylinder 310 is further provided with a baffle 370. The baffle 370 moves on the top of the mounting cylinder 310 through the tightness of a bolt 371. The baffle 370 is provided with a sliding groove 372, and the bolt 371 passes through the sliding groove 372 and enters a mounting hole 314 arranged on the mounting cylinder 310 to limit the position of the baffle 370. The icing detector 300 is connected with the mounting rod 200 through the adjustable connecting frame, so that the installation angle and height of the detector can be flexibly adjusted to adapt to different road surface 100 environments and different angle detection requirements; the sectional arrangement of the first connecting part 330, the second connecting part 340 and the third connecting part 350 of the mounting rod 200 enhances the installation flexibility of the structure. The baffle 370 is arranged on the top of the mounting cylinder 310, and the cooperation of the bolt 371 and the sliding groove 372 enables the baffle 370 to be adjusted and fixed in position on the top, effectively preventing rain, snow, dust and the like from entering the mounting cylinder 310 from the top, further protecting the internal elements, while facilitating the adjustment of the position of the baffle 370 according to environmental requirements, improving the adaptability and protection performance of the equipment.

[0041] Please refer to Figure 2 And Figure 3The second connecting part 340 is provided with a rotating space 341 at one end connected with the first connecting part 330. The first connecting part 330 can be installed in the rotating space 341 and provided with a rotating space for angle adjustment. The second connecting part 340 is provided with a hinge hole 342 at both sides of the rotating space 341. One end of the first connecting part 330 is arranged in the second connecting part 340 through the rotating space 341 and hinged with the second connecting part 340 through a rotating shaft 343 arranged in the hinge hole 342 at both sides of the rotating space 341. When the angle adjustment is completed, the rotating shaft 343 is fastened to limit the rotation of the rotating shaft 343, so that the angle of the ice detection is fixed. By arranging the rotating space 341 at one end of the second connecting part 340 connected with the first connecting part 330 and arranging the hinge hole 342 at both sides of the rotating space 341, the first connecting part 330 can be hinged with the second connecting part 340 through the rotating shaft 343. This arrangement allows the first connecting part 330 to rotate freely within a certain range, thereby realizing flexible adjustment of the installation angle of the ice detector 300 to adapt to different detection directions and position requirements. At the same time, this hinge structure has high stability and can be firmly fixed after adjustment to ensure the reliability and accuracy of the device during use.

[0042] In actual application, the icing conditions of different road sections are significantly different. It is quite difficult to cover a wide area by relying on manual detection means, because it requires a large amount of manpower and time. However, if the icing conditions are not detected, the safety of driving cannot be ensured. Taking a long downhill road section as an example, if the driver does not know the icing conditions of this road section, he or she may encounter the problem of delayed braking or excessive braking distance when descending, which will increase the risk of traffic accidents such as rear-end collision or vehicle skidding. In addition, even for the same slope, the icing conditions of different areas may be quite different. Therefore, in order to ensure the safety of driving, it is essential to use the ice detector 300 to monitor the icing conditions of these road sections in real time.

[0043] Please refer to Figure 2 and Figure 3The end of the third connecting part 350 connected with the second connecting part 340 is provided with a plurality of evenly distributed clamping grooves 351, which are angularly spaced. The different angles of installation are achieved by clamping the clamping grooves 351 with different clamping blocks. By setting a plurality of evenly distributed clamping grooves 351 at the end of the third connecting part 350 connected with the second connecting part 340, and clamping and fixing with clamping blocks, the quick adjustment and stable connection of the third connecting part 350 and the second connecting part 340 can be achieved. This structure allows the mounting rod 200 to be fixed at different angles, thereby meeting the installation requirements of various angles and improving the adaptability of the device in complex road surface 100 environment. At the same time, the clamping method is simple and flexible to operate, which can significantly improve the installation and maintenance efficiency.

[0044] Please refer to Figure 2 and Figure 3 The third connecting part 350 is provided with a mounting seat 352 at the end away from the second connecting part 340; the icing detector 300 is stably arranged on the mounting rod 200 through the mounting seat 352. The first connecting part 330, the second connecting part 340 and the third connecting part 350 are all provided with through cavities 360 for wiring. In this way, the wires and signal lines can be hidden inside the connecting parts and wired through the through cavities 360. This internal wiring method not only effectively protects the wires from external environmental factors such as rain, snow, wind and sand, but also greatly improves the appearance and safety of the wiring of the entire device. At the same time, since the wires are hidden inside, it provides great convenience for the maintenance and replacement of the wires, thereby reducing the risk of equipment downtime caused by wire problems and ensuring the stable operation of the equipment.

[0045] Please refer to Figure 2 and Figure 3At one end of the mounting cylinder 310, a structure for mounting the shooting unit 312 is provided, and at this end, a cylinder cover 315 is also mounted; the cylinder cover 315 and the mounting cylinder 310 are connected through a detachable connection mode, which ensures that the cylinder cover 315 can be simply mounted or detached. In this way, the cylinder cover 315 can completely encapsulate the detection component 320 and the shooting unit 312 inside the mounting cylinder 310, thereby providing a closed protective environment. By arranging the shooting unit 312 at one end of the mounting cylinder 310, the cylinder cover 315 realizes the overall encapsulation of the detection component 320 and the shooting unit 312, which can effectively prevent external dust, rain, snow and other adverse factors from invading the inside of the equipment, thereby protecting the internal precision components from damage, and also can provide a more stable and safe working environment for the equipment. In addition, due to the detachable nature of the cylinder cover 315, when the user needs to maintain, clean or replace the internal components, the cylinder cover 315 can be easily detached, which greatly facilitates the user's operation and improves the operability of the equipment. At the same time, this design also ensures the reliability of the equipment during long-term use, so that the equipment can run more stably, thereby prolonging the service life of the equipment.

[0046] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
