[0030] Embodiment 1

[0031] Please refer to Figure 1 The embodiments of the present application provide a road surface icing detection and early warning device, which adopts at least two different detection methods and combines with an early warning function, and can issue corresponding warning signals according to different icing conditions. The main purpose of this device is to provide real-time road condition information to drivers, so as to provide important reference for them during driving and ensure driving safety.

[0032] Please refer to Figure 1In the present embodiment, the road icing detection and early warning device comprises a mounting portion 100, an icing detector 200 and a warning unit 300 mounted on the mounting portion 100. The mounting portion 100 is the base of the entire device, which is responsible for bearing the icing detector 200 and the warning unit 300, ensuring that they can be placed in a suitable position. In this way, the icing detector 200 can effectively monitor the road surface within a predetermined range and assess the icing degree of the area. Once icing is detected, the warning unit 300 will alert the driver through visual, audible or pre-warning information, informing them of the current road conditions, so as to help the driver respond in time and ensure driving safety.

[0033] Further, referring to Figure 1 , the mounting portion 100 is installed on one side of the road, and the mounting portion 100 is composed of two main parts, namely the first mounting rod 110 and the second mounting rod 120. A support rod 130 is additionally provided between the two mounting rods. The main function of the first mounting rod 110 is to provide sufficient longitudinal height, while the second mounting rod 120 is responsible for providing the necessary lateral extension length. Such a setup allows the icing detector 200 and the early warning unit to be placed in an ideal detection position, ensuring that their functions are fully realized. In actual application, if the length of the second mounting rod 120 is set too long, combined with the early warning unit, it may be at risk of breaking due to excessive weight. To solve this potential problem, a support rod 130 is provided between the first mounting rod 110 and the second mounting rod 120, with both ends connected to the two mounting rods. Through such a structural design, the first mounting rod 110, the second mounting rod 120 and the support rod 130 together form a stable triangular structure. This structure not only has an aesthetic appearance, but also has high stability, effectively avoiding structural damage due to gravity, thereby ensuring the long-term stable operation of the icing detector 200 and the early warning unit.

[0034] In the present embodiment, referring to Figure 1, the first mounting rod 110 is also equipped with a controller 400 responsible for managing and coordinating the operation of the entire system. In addition, the icing detector 200 is installed at a suitable position of the first mounting rod 110 to accurately monitor the icing conditions that may affect road safety. In order to ensure that the driver can receive important safety warning information in time during driving, the warning unit 300 is arranged on both sides or above the road, so that the driver can easily observe the information displayed on the warning unit 300 during normal driving. The warning unit 300 and the icing detector 200 are connected to the controller 400, so that the controller 400 can control the information content displayed on the warning unit 300 according to the detected data, thereby providing real-time road condition information to the driver. In order to protect the internal lines and ensure their safety, a cavity for wiring is provided inside the connection structure, and the lines enter the inside of the first mounting rod 110 through the cavity and are connected to the controller 400, which not only ensures the neatness and durability of the lines, but also improves the stability and reliability of the entire system.

[0035] In this embodiment, the controller 400 is responsible for triggering warning signals of corresponding levels according to the collected icing information and preset different thresholds. These thresholds are set to different values to distinguish different degrees of icing. When the icing information reaches or exceeds a certain threshold, the controller 400 activates the warning unit 300 to issue a warning to the operator or related system. The design of the warning unit 300 includes an LED display screen that can visually display warning information. Specifically, the LED display screen can display warning words, and different frequencies and modes of flashing can represent warning signals of different emergency levels. In addition, the warning unit 300 can also include a voice prompt function to further enhance the warning effect in the form of sound, ensuring that the information can be noticed in time.

[0036] Further, when driving alone in winter, the driver will only use a small amount of time to obtain information on the information acquisition device (mobile phone), and needs to focus on driving to cope with different road conditions; therefore, an LED screen that can be observed during normal driving of the driver is needed, so that the driver can understand the road condition information in time during normal driving without the assistance of the copilot, ensuring the safe driving of the driver.

[0037] Further, during winter driving, the driver often turns on the heater, but long-term exposure to a warm environment can make the driver drowsy, leading to incorrect and timely judgments based on road condition information. Therefore, a voice prompt function is needed to further enhance the warning effect in the form of sound, which can not only prompt the driver of the road condition information, but also to some extent solve the problem of the driver's drowsiness.

[0038] Further, in order to more accurately reflect the severity of icing conditions, the threshold of the icing information includes at least three different levels: a first threshold, a second threshold, and a third threshold. These thresholds correspond to light, medium, and severe icing conditions, respectively. When the icing information reaches the first threshold, it indicates that the icing condition is relatively light, and the warning unit 300 will issue corresponding warning information to remind relevant personnel. When the icing information reaches the second threshold, it means that the icing condition has escalated to a medium level, and the warning unit 300 will issue a higher level of warning information. When the icing information reaches the third threshold, it indicates that the icing condition is very serious, and the warning unit 300 will issue the highest level of warning information to ensure that sufficient attention is drawn and appropriate emergency measures are taken. Through this hierarchical warning mechanism, different severity of icing conditions can be effectively managed and responded to.

[0039] For example, in the case where the icing information matches the first threshold, it indicates that the road surface has not yet reached the icing state, but there is a certain degree of wetness. In this case, a warning sign is set up to issue a wetness warning to remind passing vehicles and pedestrians of the road surface conditions.

[0040] When the icing information matches the first threshold, it indicates that the road surface has begun to show signs of icing and is no longer simply wet. In this case, the warning system will issue a skid warning through the set warning sign, and the remote communication system in the controller 400 will be activated to send warning information to the information acquisition device of the driver or relevant staff, so that they can timely understand the road surface conditions and take appropriate preventive measures.

[0041] When the icing information matches the third threshold, it indicates that the road surface has formed a relatively serious ice surface, and the skid condition has become quite serious, and even manual deicing measures may be required. In this case, the warning sign will issue a severe skid warning and remind passing vehicles to reduce speed to ensure safe driving. The warning device assists the driver in safe driving, helping them better cope with the poor road conditions and ensure safe driving.

[0042] Referring to Figure 2 , the icing detector 200 includes a hollow shell 210, and a detection unit 220 and a camera unit 230 arranged inside the shell 210; wherein the detection unit 220 is composed of a transmitter 211 and a receiver 222.

[0043] Referring to Figure 2 and Figure 5The transmitter 211 is responsible for emitting detection laser to the road surface, while the receiver 222 is responsible for receiving the detection laser reflected from the road surface. To achieve this function, the transmitter 211 is composed of multiple laser diodes, and the receiver 222 is composed of multiple receiving lenses. These laser diodes and receiving lenses are arranged around the camera unit 230. The ice detector 200 not only includes an ice sensor, but also contains a camera unit 230; wherein the ice sensor is used to detect the icing degree of the road surface and output the corresponding ice information threshold; and the visual sensor is responsible for real-time shooting and transmission of the image of the road surface. Through this design, the ice detector 200 realizes the cooperation of optical detection and visual detection, which makes it can effectively distinguish the icing state from other similar situations (such as water accumulation, dry surface), thereby significantly improving the accuracy and applicability of detection. In addition, the shooting unit can also provide real-time pictures of the icing situation, which not only provides a strong basis for later analysis, but also can be used as a reference for road management, thereby greatly improving the functionality and practicality of the detection device.

[0044] Please refer to Figure 4 and Figure 5 In this embodiment, laser detection technology is adopted; specifically, the laser ice detector 200 is composed of two parts: a laser transmitter 211 and a receiver 222. The laser transmitter 211 uses a light source (laser diode) to emit high-frequency and directional laser beams. When these laser beams irradiate the road surface, part of the laser beams will be reflected by the road surface and returned to the receiver 222. The reflection characteristics of laser are closely related to many factors such as the physical state of the road surface, the surface material, the temperature and the humidity. In particular, when the road surface appears icing phenomenon, the reflectivity and scattering characteristics of the ice layer surface are significantly different from the un-iced road surface. The ice layer surface is usually smoother, which causes the intensity and angle of laser reflection to change accordingly. Therefore, by analyzing these changes in laser reflection signals, the detector can effectively distinguish the icing area and the normal road surface. The ice sensor (laser sensor) usually has the ability to measure the time difference of the laser beam from emission to reception, or uses the principle of triangulation to obtain distance information. When the sensor receives the reflected signal, combined with the known speed of light, the exact distance of the light beam from the sensor to the ice layer can be calculated. By continuously measuring several times, the detector can accurately obtain the thickness of the ice layer, or judge whether the thickness of the ice layer has exceeded the preset safety threshold. The ice sensor (laser sensor) judges the icing condition by analyzing the received reflection signal. If the reflectivity, time difference or thickness of the signal exceeds the set threshold, the detector will trigger the alarm mechanism to remind the driver or traffic management personnel of the icing condition, and can be connected with traffic signal system, warning signs and other devices to provide timely warning information.

[0045] Further, in the present embodiment, the laser icing detector 200 employed utilizes a laser detection technology that is widely recognized and technically mature in the field of icing, water accumulation, or snow accumulation detection. This technology has been proven to be highly efficient and reliable in practical applications. In the present embodiment, the detection principle of the laser icing detector 200 can refer to the detection principle of the RD3000 non-contact road surface condition detector produced by Ashworth Company. The RD3000 detector is an advanced device that uses laser technology to monitor road conditions, including but not limited to icing, water accumulation, and snow accumulation. By emitting a laser beam and analyzing its reflected signal, the RD3000 can accurately detect the condition of the road surface, providing important data support for road safety. The application of this detection technology not only improves the accuracy of detection, but also greatly enhances the efficiency and response speed of road maintenance.

[0046] Inside the shell 210, a detection unit 220 and a camera unit 230 are arranged, and one end of each is equipped with an isolation lens; and the detection unit 220, the camera unit 230, and the isolation lens are packaged inside the shell 210 by the shell cover 212, ensuring their safety and stability.

[0047] Please refer to Figure 2 , in order to further protect the internal detection unit 220, the shell 210 is provided with a shielding plate 211 for shielding the top of the shell 210. It not only effectively prevents the intrusion of dust and moisture from the outside, but also provides additional protection for the internal detection unit 220. The shell cover 212 and the shielding plate 211 are made of waterproof and dustproof materials, ensuring that the entire device can work normally in various environments, and also facilitating the user's maintenance and cleaning.

[0048] Please refer to Figure 1 and Figure 3 , the icing detector 200 is connected to the mounting portion 100 through a connecting mechanism 240, which includes a first connecting portion 241 and a second connecting portion 242, and a connecting piece 247 for connecting the first connecting portion 241 and the second connecting portion 242; through this connecting mechanism 240, the icing detector 200 can realize at least two degrees of freedom of icing detection adjustment angle, so that the icing detector 200 can flexibly adjust its detection angle.

[0049] Please refer to Figure 3 , on the connecting piece 247, a first rotating groove 245 and a hinge groove 246 arranged on both sides of the first rotating groove 245 are arranged; one end of the icing detector 200 is connected to the mounting seat 243, and the other end of the mounting seat 243 is hinged through the first rotating groove 245 and the hinge groove 246, so as to realize flexible adjustment of the icing detector 200.

[0050] The second connecting part 242 is provided with a mounting seat 243 and a second rotating groove 244; a connecting piece 247 is hingedly connected to the second rotating groove 244 at an end away from the first connecting part 241; and the icing detector 200 is fixedly connected to the second mounting rod 120 through the mounting seat 243, further ensuring the stability and reliability of the icing detector 200.

[0051] Please refer to Figure 3 In the embodiment, the icing detector 200 is connected to the mounting part 100 through the connecting mechanism 240, and the angle adjustment of the icing detector 200 is realized by using the adjustment mechanism with multiple degrees of freedom. The connecting mechanism 240 is composed of a first connecting part 241, a second connecting part 242 and a connecting piece 247, wherein the first connecting part 241 is directly connected to the icing detector 200, and the second connecting part 242 is connected to the mounting rod. By providing a rotating groove and a hinged groove 246 on the connecting piece 247, the icing detector 200 can be angle-adjusted on the mounting part 100 to adapt to the monitoring requirements under different road sections and different environmental conditions. This flexible adjustment mechanism can ensure that the detector can always accurately scan the road surface area that needs to be monitored most, thereby significantly improving the accuracy and reliability of the icing detection.

[0052] Please refer to Figure 3 The angle adjustment of the icing detector 200 is realized by the rotating groove and the hinged groove 246 on the connecting piece 247. When adjusting, the rotating groove allows the icing detector 200 to rotate around an axis, and the hinged groove 246 provides stable support to ensure that the detector can be fixed at the target angle during the adjustment process. After the adjustment is completed, the detector is fixed at the set angle through the hinged groove 246, ensuring stable operation of the detector and providing accurate road icing monitoring data, thereby providing strong guarantee for road safety.
