Description

Technical Field

[0001] The utility model relates to the technical field of road traffic safety, in particular to a highway sight line induction device. Background Art

[0002] Currently, my country's expressways and some national and provincial highways lack full lighting coverage. At high speeds, drivers rely on their naked eyes to capture information about the road ahead, either from headlights or natural light reflected from surrounding objects. When visibility is reduced due to sudden changes in weather conditions, such as at night, during foggy conditions, or during heavy rain, drivers' safe vision distance is shortened, and the braking time available to handle emergencies is also reduced. Furthermore, contaminated road markings can easily cause vehicles to brake untimely, causing them to run off the road or rear-end collisions. Therefore, advance knowledge of the road ahead and understanding of speed limits are crucial for the safety of vehicles on the road. In recent years, traffic safety products have emerged that actively illuminate or passively reflect road surfaces, such as road shoulders, to indicate road alignment to drivers. These include road-attached luminous delineators and fog zone guidance devices.

[0003] Highway-attached luminous delineators rely on short-range wireless communication modules for signal transmission, with several to dozens of yellow LED lamp beads flashing at a fixed frequency. As recorded in the existing Chinese utility model patent CN209907240U "A temporary attached active luminous delineator device for highways", the device is turned on and off by a short-range communication module, and the entire device is adsorbed into the groove of the corrugated guardrail by magnetic attraction. In actual engineering applications, this type of product is small in size and the groove that carries the corrugated guardrail is close to the road surface, so the luminous surface is easily contaminated. It also has a high damage rate due to damage caused by car accidents, scratches by guardrail cleaning vehicles, etc. Damage to one or more nodes will cause the short-range communication module transmission link to be interrupted, thereby affecting the road safety guidance effect. So far, it has been difficult to install and promote it on a large scale on highways.

[0004] Fog guidance equipment is a roadside active lighting guidance device that has been widely developed in the road traffic industry in recent years. The device uses dozens of LED beads to illuminate simultaneously. They have a large luminous area, high light intensity, and good penetrating power. They are often used in foggy and rainy days, where visibility is extremely limited and driving speeds are slow, by reflecting halos from thick fog or exhaust particles to create a visible light band for drivers. Existing Chinese utility model patent CN203807974U, "A fog-area guidance light installed on the side of a highway," describes a high-brightness illuminator using yellow and red-and-white dual-color LED lights. However, highways mostly require lighting at night when seeing conditions are high. The high brightness of these devices when turned on can easily cause discomfort to the driver's optic nerves. Deployed over a large area, they seriously impair the driver's ability to judge road conditions, making traffic accidents easily caused by obstructed vision. The dominant yellow light source is not distinct, and some use red lights for high-level warnings, which can easily give drivers a psychological "no go, stop" warning. Emergency braking at highway speeds can easily cause traffic accidents. These devices only have a flashing light function and cannot provide targeted, intuitive interaction with the driver regarding speed control and driving direction.

[0005] In summary, the above two patent cases represent the current technological trend. Due to the widespread use of yellow lamp beads, the yellow color has low brightness and is not obvious, and the luminous effect is a point-like light source, which cannot effectively and continuously mark the linear direction of the road.

Therefore, they should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components.

[0022] In this embodiment, if Figures 1 to 5As shown, a highway sightline guidance device includes a bracket 11 positioned on one side of a guardrail 12. A mounting plate 10 is mounted on the upper end of bracket 11, onto which a housing 9 is mounted. Batteries 8 are located on either side of housing 9. A retroreflector 5 is located at the front end of housing 9, and a light-transmitting cover 3 is located on the side of retroreflector 5. A diode 4 is located within light-transmitting cover 3. Diode 4 is located on an annular prism 1. A reflector 2 is located in the center of annular prism 1. Battery 8 is used to power diode 4. When ambient light is sufficient, reflector 2 directly absorbs ambient light or headlight light and reflects it directly toward oncoming vehicles. When ambient light is insufficient, diode 4 emits light that is softened and focused by annular prism 1. In other words, annular prism 1 circularizes the light emitted by diode 4, trapping it within itself to create a light-guiding effect. This converges and softens the light, resulting in a green or other colored ring-shaped light source, creating a uniform and soft planar light source. After being focused by the retroreflector 5, the light is emitted toward the oncoming vehicle. Meanwhile, the reflector 2 continues to directly absorb ambient light or headlight light and reflects it directly toward the oncoming vehicle. This results in a narrow scattering angle, a small illumination area, and high brightness, enhancing the guidance effect. Furthermore, because the light is softened and reflected and focused, the processed light does not directly affect the driver's eyes. In this embodiment, the devices are installed longitudinally and continuously at intervals of 8 to 12 meters on the shoulder of a highway. The light source of the diodes 4 is an LED lamp bead, which is green, yellow, blue, or white.

[0023] Furthermore, a control circuit board 6 is disposed at the upper end of the housing 9. A solar panel 7 is also disposed at the upper end of the control circuit board 6. Both the solar panel 7 and the battery 8 are electrically connected to the control circuit board 6. Specifically, the control circuit board 6 comprises a charging and discharging section, a control section, a power supply section, and a wireless communication section. The wireless communication section is a medium- and long-range broadcast multipoint transceiver module that receives control commands from the outside in real time and transmits these commands to other similar devices. The control section controls the energy consumption of its own power supply system. Specifically, the control circuit board 6 controls the power supply from the battery 8 to the diode 4, thereby adjusting the flashing frequency, flashing brightness, and light combination operating mode of the device. Different operating modes are achieved through light combinations, achieving functions such as strengthening road markings, providing driving direction guidance, and indicating speed limits on sections. The solar panel 7 is used to convert solar energy into electrical energy, which is stored in the battery 8 under the control of the control circuit board 6. In this embodiment, the control circuit board 6 is controlled using existing methods, which have not been improved upon and will not be further described.

[0024] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
