Description

Technical Field

[0001] This utility model relates to the field of road icing detection technology, and in particular to a mobile roadside icing detector. Background Technology

[0002] With the rapid development of modern transportation, winter road safety has become a focus of attention for traffic management departments worldwide. Especially in cold regions, frequent road icing is a major contributing factor to traffic accidents. Icing not only poses a direct threat to vehicle safety but also negatively impacts the efficiency of the entire transportation system. Therefore, effectively detecting and addressing road icing has become an urgent problem. Currently, various road icing detection technologies have been developed, including temperature and humidity detection, infrared temperature measurement, electrical resistance methods, and optical detection methods. These technologies have demonstrated their effectiveness in different application scenarios, but some shortcomings remain. For example, fixed detection equipment is typically installed at specific monitoring points, such as bridge or tunnel entrances. However, the coverage of such equipment is relatively limited, making it difficult to meet the needs of large-scale, multi-segment icing monitoring. Furthermore, once fixed equipment is installed, the flexibility to adjust its location or expand its coverage is low, which limits the improvement of detection efficiency. Some existing technologies rely primarily on changes in ambient temperature and humidity to indirectly infer whether the road surface is icy, but this method cannot directly detect the thickness of the ice layer. Because this indirect method is easily affected by external environmental factors, such as wind speed, road surface material, and solar radiation, the test results obtained are often not accurate enough.

[0003] The patent "An Icing Detection Device Based on Parallel Light Detection of Ice Thickness" (Publication No. CN210426445U, hereinafter referred to as Prior Art 1) discloses an icing detection device. In Prior Art 1, the transmitter and receiver are mounted on a specific bracket and maintained at a certain distance. The transmitter is responsible for emitting parallel light beams, while the receiver is responsible for receiving these parallel light beams and processing the received data. For testing, a test rod is placed in the middle of the distance between the transmitter and receiver and is also fixed to the bracket. The function of this test rod is to block a portion of the parallel light beam emitted by the transmitter, thereby forming a specific blocking area in the beam path. The transmitter itself consists of several key components, including an emitting housing, a light source, a scattering device, and a standard mirror. These components are all installed inside the emitting housing, where the light source is responsible for emitting the initial light beam, which is then processed sequentially by the scattering device and the standard mirror to finally form a precise parallel light beam. On the other hand, the receiver consists of a receiving housing, a telecentric optical device, and a linear photosensitive device. The telecentric optics and linear photosensitive sensor are both housed inside the receiver housing. The telecentric optics are specifically designed to receive the corresponding parallel beam of light and transmit it to the linear photosensitive sensor. The linear photosensitive sensor can detect the specific locations of unobstructed areas and areas blocked by the test probe within the beam, thereby calculating the size of the object being measured. The receiver also features an external output interface, which can be connected to other external devices to transmit information related to ice thickness. Furthermore, mounting holes are located on the top of the bracket, allowing for easy installation of the entire device at the desired measurement location.

[0004] However, existing technology 1 has certain limitations. It can only detect the road surface at a preset location and cannot cover multiple different detection locations. This makes it difficult to flexibly meet the needs of monitoring different areas of the road and cannot provide comprehensive road condition information. This limitation of existing technology 1 is particularly prominent when continuous monitoring of multiple areas is required. Utility Model Content

[0032] Example 1

[0033] Please see Figure 1 This utility model provides a mobile roadside icing detector, whose main function is to detect the degree of icing on the road surface, thereby assessing driving safety.

[0034] In this embodiment, the mobile roadside icing detector includes a movable mounting frame and an icing detector mounted on the frame. The movable mounting frame comprises at least two parts, respectively located on both sides of the road, while the icing detector is mounted on the frame. This allows the icing detector to perform mobile detection of the road surface based on the movable mounting frame, thus enabling wider coverage of the icing detection area. In this way, the degree of road icing in different areas can be assessed, and the driving safety level of each area can be determined accordingly.

[0035] In practical applications, icing detectors are typically deployed in areas with harsh environmental conditions. These areas have complex and variable road conditions, with many potentially icy sections. Due to the complexity of these road sections, manual inspection is both time-consuming and labor-intensive, and inefficient. Especially in winter, when holidays arrive, workers often take time off, while many drivers choose to go home or travel. To ensure the safety of these drivers, especially under adverse weather conditions, it is crucial to use icing detectors for real-time monitoring of road sections that are difficult to cover manually. This method provides drivers with timely updates on real-time road conditions, effectively reminding them to pay attention to driving safety and preventing traffic accidents caused by icy roads.

[0036] Further, please see Figure 1 The movable mounting frame includes a first mounting frame 100 and a second mounting frame 200 spaced apart and respectively located on both sides of the road; the icing detector includes a transmitter 310 and a receiver 320 respectively located on the first mounting frame 100 and the second mounting frame 200; the first mounting frame 100 and the second mounting frame 200 are symmetrically arranged; the first movable seat 110 and the second movable seat 210 move synchronously.

[0037] Please see Figure 1The icing detector operates by using a parallel detection beam 330 to assess the severity of road icing. This icing detector employs a unique method for detecting ice thickness based on the parallel detection beam 330. The core of this method lies in the parallel detection beam 330 emitted by the transmitter 310. When this beam passes through the road surface being inspected, the presence of ice partially blocks it, resulting in unblocked and blocked areas on the linear photosensitive sensor of the receiver 320. Telecentric optics inside the receiver 320 receive these parallel beams and transmit them to the linear photosensitive sensor. The linear photosensitive sensor uses a photodiode array to convert the received light signals into electrical signals and records the position and signal strength information of each photodiode. In areas unblocked by ice, a strong electrical signal is generated due to sufficient light; while in areas blocked by ice, the corresponding electrical signal is weak or nonexistent due to weak or absent light. The microprocessor integrates these electrical signals and position information to calculate the size of the area blocked by ice on the road surface, thereby estimating the change in ice thickness. Finally, the detection results are transmitted through the output interface of receiver 320 to achieve accurate measurement of the degree of road icing.

[0038] In practical operation, the transmitter 310 and receiver 320 of the icing detector can effectively cover specific areas of the road. This coverage method ensures comprehensive coverage of the entire detection area during ice surface detection, thereby guaranteeing the accuracy and reliability of the detection results. In this way, both drivers and traffic management departments can obtain accurate information about road conditions and take appropriate measures to ensure driving safety.

[0039] To ensure the accuracy of the detection, the transmitter 310 and receiver 320 are designed to be installed at the same height. This installation method allows the receiver 320 to receive the parallel beam from the transmitter 310 with minimal error, thereby guaranteeing the accuracy and reliability of the detection data.

[0040] Please see Figure 1In this embodiment, the first mounting bracket 100 and the second mounting bracket 200 are designed to support specific components. Specifically, each of the two mounting brackets is equipped with a first movable seat 110 and a second movable seat 210 that can move along their respective mounting brackets. The arrangement of these movable seats allows for precise positioning and movement on the mounting brackets. Furthermore, to achieve the function of detecting the degree of road icing, the transmitter 310 and the receiver 320, two key components, are respectively mounted on the first movable seat 110 on the first mounting bracket 100 and the second movable seat 210 on the second mounting bracket 200. These two components work together; the transmitter 310 is responsible for emitting parallel light beams, while the receiver 320 is used to receive these light beams. When these parallel light beams pass through the road surface, they are affected by the ice layer, causing changes in the intensity of the light beam received by the receiver 320. By analyzing these changes, the thickness of the ice surface can be accurately measured, thereby assessing the degree of road icing.

[0041] Please see Figure 1 and Figure 4 In this embodiment, the first mounting frame 100 is composed of a first support frame 120 and a second support frame 130 respectively provided at both ends. At the same time, a first guide rail 141 and a second guide rail 142 are provided between the first support frame 120 and the second support frame 130. These guide rails are connected to the support frame by a fixed assembly, so that the first movable seat 110 and the second movable seat 210 can move on the first guide rail 141 and the second guide rail 142.

[0042] Please see Figure 1 , Figure 2 and Figure 4 To ensure structural stability and load-bearing capacity, the first support frame 120 and the second support frame 130 are respectively equipped with a first bearing 121 and a second bearing 131 with the same axis. A rotating lead screw 143 can be installed between the first support frame 120 and the second support frame 130 via these two bearings to achieve specific mechanical movements. Furthermore, to protect the bearings from external environmental influences, both the first bearing 121 and the second bearing 131 are provided with protective covers 144, which effectively extends the service life of the bearings and ensures their normal operation.

[0043] Further, please see Figure 2 A third support frame 150 is specially provided outside the second support frame 130; a drive motor 151 is provided outside the third support frame 150 to provide power and drive the movement of the entire device.

[0044] The output shaft of the drive motor 151 is connected to one end of the rotating lead screw 143 through the coupling 152 to form a transmission connection. This allows the power of the motor to be effectively transmitted to the rotating lead screw 143, thereby driving the movement of the entire device and realizing the synchronous movement of the receiver 320 and the transmitter 310.

[0045] Please see Figure 1 and Figure 3 The first movable seat 110 includes a mounting plate 111 and a slider disposed at the bottom of the mounting plate 111; these sliders enable the first movable seat 110 to be connected to the first guide rail 141 and the second guide rail 142 respectively through at least a pair of sliders disposed at the bottom, thereby achieving smooth movement.

[0046] Please see Figure 2 To achieve connection with the rotating lead screw 143, a threaded sleeve 113 is also fixedly provided at the bottom of the mounting plate 111 of the first movable seat 110. Through the hinge between the threaded sleeve 113 and the rotating lead screw 143, the rotational motion of the rotating lead screw 143 can be converted into the linear motion of the first movable seat 110, thereby achieving precise control of the moving position. The icing detector is securely fixedly mounted on the mounting plate 111. In terms of structural design, the transmitter 310 and the receiver 320 are positioned relative to each other.

[0047] Please see Figure 1 During installation, the first mounting bracket 100 and the second mounting bracket 200 are respectively placed on both sides of the road surface to be inspected, precisely mounting the transmitter 310 and receiver 320 of the icing detector. This arrangement ensures that the receiver 320 can effectively receive the parallel beam of light from the transmitter 310 used to detect the ice thickness; at the same time, the first mounting bracket 100 can be flexibly mounted on the road guardrail via the first support bracket 120 and the second support bracket 130 mounted on it, thereby saving installation space.

[0048] Please see Figure 1 The movement of the first and second mounting seats relies on a lead screw drive system. The drive motor 151 transmits power to the rotating lead screw 143 via a coupling 152. The rotation of the lead screw 143 engages with the threaded sleeve 113 on the mounting seat, converting rotational motion into linear motion through a helical transmission principle, thereby driving the movable seat to move along the guide rail. By synchronously driving two different rotating lead screws 143, the first and second mounting seats can maintain synchronous movement, ensuring that the transmitter 310 and receiver 320 always maintain their relative positions.

[0049] Please see Figure 1During use, the transmitter 310 emits a parallel beam of light to detect the thickness of the ice surface, while the receiver 320 receives these beams. By analyzing the blocked and unblocked areas within the parallel beams, the degree of icing can be accurately determined.

[0050] Please see Figure 1 When a different location needs to be detected, both drive motors 151 will start simultaneously and operate in the same mode. They drive the rotating lead screw 143, causing the first moving seat 110 and the second moving seat 210 to move synchronously. The first moving seat 110 and the second moving seat 210 move precisely based on the first guide rail 141 and the second guide rail 142, thereby driving the transmitter 310 and the receiver 320 to cover different detection positions and detect the ice surface. In this way, the function of detecting the ice surface at different locations can be realized.

[0051] In other embodiments, the icing detector is further equipped with a controller, which can receive control signals from a remote location and also send signals to control the icing detector to operate. In practical applications, icing detectors are typically deployed in areas with harsh environmental conditions, where road conditions are complex and varied, and many potentially icy road sections need to be detected. When detection is required, the icing detector can be moved along a guide rail by remote control from personnel to achieve detection within the expected range.

[0052] Furthermore, during the inspection, there may be other situations besides icing, such as rocks and debris accumulating on the road. When the icing detector determines that there is an obstruction, it can use point-based detection to determine the nature of the obstruction and provide the driver with appropriate driving reminders.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
