Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of municipal construction, and in particular to a smart luminous road barrier. Background Technology
[0002] When driving at night, drivers' attention is usually focused on the road surface. When encountering unfamiliar roads, they may easily overlook the location of intersections due to limited visibility and insufficient attention allocation. This makes it difficult to detect the movement of pedestrians at intersections and the road conditions ahead in time, which may lead to traffic accidents due to untimely judgment and delayed reaction.
[0003] In existing technologies, commonly used warning facilities at intersections, such as traditional road barriers and fixed indicator lights, are mostly static warning methods. They can only provide fixed intersection boundaries or directional markings and cannot reflect the presence status of pedestrians, their walking trajectory, and the specific distance information of the intersection ahead in real time and dynamically. Especially in poor environments such as dim lighting, rain, and fog, their warning effect is further weakened, making it difficult to effectively assist drivers in quickly identifying intersection risks. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in the related art.
[0005] Therefore, the purpose of this utility model is to propose a smart luminous road barrier that can detect the presence, location and dynamics of pedestrians from multiple dimensions, thereby improving the accuracy of pedestrian detection at intersections; provide multi-form lighting coordination prompts to enhance drivers' perception of the status and distance of pedestrians at intersections; and intelligently control the start and stop of lights to balance safety and energy saving.
[0006] To achieve the above objectives, this utility model proposes a smart illuminated road barrier, which is equipped with indicator lights and marker lights. Each indicator light and marker light includes a spotlight bulb, a circuit board, and a housing. The barrier includes: a road post, with mounting frames on both sides; the mounting frames are multi-layered boards, each layer equipped with an arrow light, the illumination angle of adjacent arrow lights increasing sequentially along the road's extension direction; sensor mounting bases, with microwave and laser sensors mounted on both sides of the road post; and a control circuit, with the indicator lights, marker lights, arrow lights, microwave sensors, and laser sensors all electrically connected to the control circuit.
[0007] This utility model's intelligent luminous road barrier can detect the presence, location, and movement of pedestrians from multiple dimensions, improving the accuracy of pedestrian detection at intersections; it provides multi-form lighting coordination prompts, enhancing drivers' perception of pedestrian status and distance at intersections; and it intelligently controls the start and stop of lights, balancing safety and energy efficiency.
[0008] In addition, the smart illuminated road barrier proposed in this application may also have the following additional technical features:
[0009] Furthermore, it also includes a 360-degree panoramic camera, which is mounted on the roadside railing via a camera bracket.
[0010] Furthermore, the light-emitting surface of the indicator light forms an angle of 45°-60° with the road surface.
[0011] Furthermore, the LED beads of the sign light are arranged in an array, and a driver chip is integrated on the circuit board. The driver chip is connected to the LED beads via an SPI bus.
[0012] Furthermore, the arrow light has an arrow-shaped light guide plate inside; the projection distance between adjacent arrow lights is 0.5-1 meter, and the arrow light is connected to a strobe control circuit.
[0013] Furthermore, it also includes a low-light lamp, which is a ring-shaped LED light strip, and the low-light lamp is located between adjacent road posts.

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0022] The following description, in conjunction with the accompanying drawings, describes an embodiment of the intelligent illuminated road barrier of this utility model.
[0023] like Figures 1-4 As shown in the figure, the intelligent illuminated road barrier of this utility model 1 is provided with indicator lights 2 and marker lights 3; both indicator lights 2 and marker lights 3 include spotlight bulbs, circuit boards and housings; including:
[0024] Road bollard 4, with mounting frames 5 on both sides of the road bollard 4. The mounting frames 5 are multi-layered boards, with arrow lights 6 on each layer. The illumination angle of adjacent arrow lights 6 increases sequentially along the road extension direction, forming a continuous forward illumination trajectory.
[0025] Sensor mounting base 10, sensor mounting base 10 is provided on both sides of the road bollard 4, and microwave sensor 7 and laser sensor 8 are provided on the sensor mounting base 10;
[0026] The control circuit includes the indicator light 2, the marker light 3, the arrow light 6, the microwave sensor 7, and the laser sensor 8, all of which are electrically connected to the control circuit.
[0027] Specifically, in this embodiment, microwave sensor 7 detects microwave Doppler signals generated by human movement to determine "whether there is a pedestrian" and "direction of movement".
[0028] In this embodiment, laser sensor 8 accurately locates the distance between a pedestrian and road post 4 (e.g., within a range of 1 to 5 meters) through laser ranging. Both sensors simultaneously transmit electrical signals to the control circuit, achieving dual detection of "presence + position".
[0029] After receiving the sensor signal, the control circuit drives the lighting components according to the preset logic.
[0030] Indicator 2 is activated: The spotlight bulbs of Indicator 2 are activated to emit light and project light spots onto the road surface (the position of the light spot corresponds to the visual indicator of "distance to the intersection ahead", such as the distance between the light spots representing meters).
[0031] 3. Strobe light: The frequency of the spotlight bulbs is controlled by the circuit board to display the pedestrian status with a strobe effect (e.g., fast flashing indicates that the pedestrian is approaching quickly, and slow flashing indicates that the pedestrian is walking slowly).
[0032] Arrow light 6 dynamic triggering: As the illumination angle of adjacent arrow lights 6 increases, the control circuit triggers the arrow lights 6 to flash sequentially in the order of "bottom layer-middle layer-top layer", so that the arrow light spot on the road surface "moves" forward along the road, simulating the dynamic trajectory of a pedestrian walking forward.
[0033] If the dual sensors continuously detect a pedestrian, the control circuit will keep the light indicator running.
[0034] If a pedestrian leaves the detection area, the control circuit will turn off all lights after a delay of 3 to 5 seconds and return to standby mode.
[0035] In one embodiment of this utility model, a 360° panoramic camera 9 is also included, which is mounted on the roadside barrier 1 via a camera bracket.
[0036] The camera captures real-time images of the intersection and integrates them with the detection data from the microwave sensor 7 and the laser sensor 8. This data assists the control circuit in determining the number, location, and movement trajectory of pedestrians, and optimizes the triggering timing and intensity of light prompts (such as increasing the flashing frequency of arrow lights when many people gather).
[0037] In one embodiment of this utility model, the light-emitting surface of the indicator light 2 forms an angle of 45°-60° with the road surface, and is used to project distance markings on the road surface.
[0038] Specifically, at this angle, the light from the spotlight bulbs is projected onto the road surface through the light-transmitting window of the housing, forming evenly spaced light spots (such as circular signs). The spacing of the light spots corresponds to the "distance to the intersection ahead," helping drivers to intuitively judge the distance to the intersection.
[0039] In one embodiment of this utility model, the LED beads of the sign light 3 are arranged in an array, and a driver chip is integrated on the circuit board. The driver chip is connected to the LED beads through an SPI bus.
[0040] Specifically, the driver chip receives signals from the control circuit, lights up LED beads at specific locations according to a preset program, combines them into text or patterns (such as "Caution pedestrians"), and controls the lighting and off sequence of the LED beads through the SPI bus to achieve the flashing display of the pattern.
[0041] In one embodiment of this utility model, the arrow light 6 has an arrow-shaped light guide plate inside, and the light guide plate is bonded to the LED light source with optical adhesive to form an arrow projection.
[0042] The projection distance between adjacent arrow lights 6 is 0.5-1 meter. The arrow lights 6 are connected to a strobe control circuit to simulate the dynamic effect of a pedestrian walking forward.
[0043] Specifically, the arrow light 6 has an arrow-shaped light guide plate (such as PMMA material) embedded inside, and its bottom surface is tightly bonded to the LED light source (spot LED) with optical adhesive (such as silicone optical adhesive), and the light source is incident along the side of the light guide plate.
[0044] In one embodiment of this utility model, a low-light lamp 11 is also included. The low-light lamp 11 is a ring-shaped LED light strip, and the low-light lamp 11 is located between adjacent road posts 4.
[0045] Specifically, when the microwave sensor 7 or the laser sensor 8 detects a pedestrian, the control circuit drives the low-light lamp 11 to emit light continuously (such as a warm yellow constant light or low-frequency flashing), clearly marking the position of the road post through the ring halo, assisting the driver to quickly identify the intersection boundary and the area where the pedestrian exists.
[0046] In actual use, pedestrian detection is achieved by using a microwave sensor 7 to detect the presence and direction of movement of pedestrians, a laser sensor 8 to accurately locate the distance, and a 360-degree panoramic camera 9 to assist in image acquisition. The signals from all three are transmitted synchronously to the control circuit.
[0047] Signal processing and driving: Based on the detection data, the control circuit drives indicator light 2 to project a light spot on the road surface, sign light 3 to flash to show the pedestrian status, arrow light 6 to flash in angular sequence to simulate walking trajectory, and low light light 11 to illuminate the location of road posts.
[0048] Status feedback: The system provides a notification while pedestrians are present; after a pedestrian leaves, the control circuit delays for 3-5 seconds before turning off all lights and returning to standby mode.
[0049] In summary, the intelligent luminous road barrier of this utility model can detect the presence, location, and dynamics of pedestrians from multiple dimensions, thereby improving the accuracy of pedestrian detection at intersections; it provides multi-form lighting coordination prompts, enhancing drivers' perception of the status and distance of pedestrians at intersections; and it intelligently controls the start and stop of lights, taking into account both safety and energy efficiency.
