Description
Technical Field
[0001] This utility model belongs to the technical field of level crossing reminder equipment, specifically relating to a two-way reminder display device for highway service area level crossings. Background Technology
[0002] In traffic safety management at highway service area intersections, traditional two-way warning display devices typically use displays, flashing lights, and audio blasts to warn vehicles and pedestrians. For example, some existing devices use a pole fixed to one side of the zebra crossing to install an audio-visual warning device, which displays text, flashes lights, or plays a voice prompt when a pedestrian is detected.
[0003] However, such devices have significant drawbacks in practical applications: traffic is heavy in highway service areas, and large trucks usually travel in the outer lanes according to traffic regulations. When a large truck travels near a zebra crossing, the view of a small car in the inner lane is blocked by the truck's body, making it impossible to effectively observe the display content or light prompts of the traditional warning device. Consequently, it is difficult to determine whether there are pedestrians on the zebra crossing, posing a serious safety hazard. Utility Model Content
[0004] The purpose of this invention is to provide a two-way warning display device for highway service area intersections, which can reduce the occurrence of situations where drivers of small cars in the inner lane cannot effectively receive warnings from the two-way warning display device due to obstructed vision.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] A two-way reminder display device for highway service area intersections includes a main pole, on which a control host, a display screen, a sign, a pedestrian sensing device, a strobe light, an audio device, and a warning light output device are fixedly connected. The display screen, pedestrian sensing device, strobe light, audio device, and warning light output device are all electrically connected to the control host.
[0007] The warning light output device emits a warning light onto the road when it is activated.
[0008] Furthermore, the indicator light output device includes a lampshade fixedly connected to one side of the main pole, a laser lamp fixedly connected to the lower end of the lampshade, and multiple light-emitting guide tubes fixedly connected to one side of the lampshade.
[0009] Furthermore, the lampshade is internally fixedly connected to multiple semi-reflective lenses that are one-to-one opposite to the light-emitting guide tube.
[0010] Furthermore, it also includes a secondary riser fixedly connected to the road near the central guardrail, with a secondary warning light cover fixedly connected to the secondary riser, and multiple warning light output mechanisms provided at the front end of the secondary warning light cover.
[0011] Furthermore, the warning light output mechanism is a light-emitting hole, and the secondary warning lamp cover has a light-inlet slot on the side facing the light-emitting guide tube, and a light-guiding channel is formed between the light-inlet slot and the light-emitting hole.
[0012] The technical effects achieved by this utility model are as follows:
[0013] This utility model provides a two-way warning display device for highway service area intersections. Based on existing sound and light warning technology, it adds a warning light output device to release warning light onto the road, allowing drivers of small cars in the inner lane to effectively see the warning light and reducing the occurrence of situations where drivers of small cars in the inner lane cannot effectively receive the warning from the two-way warning display device due to obstructed vision.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0021] like Figure 4As shown, to more clearly explain the two-way reminder display device, we will first introduce a type of highway service area entrance. Specifically, the highway service area entrance includes a roadbed, on which zebra crossings 18 and median guardrails 19 are set. The roadbed is divided into oncoming lanes and opposite lanes by the median guardrails 19. Solid side lines 20 are fixedly connected to the side of both the oncoming and opposite lanes away from the median guardrails 19. A dashed center line 21 is set in the middle of both the oncoming and opposite lanes. The road between the median guardrails 19 and the dashed center line 21 is the inner lane, and the road between the solid side lines 20 and the dashed center line 21 is the outer lane.
[0022] Traditional two-way warning display devices are usually fixedly connected to one side of the zebra crossing 18 away from the central guardrail 19. When a vehicle passes through the zebra crossing 18, it can determine whether there are pedestrians on the zebra crossing 18 by observing the two-way warning display device.
[0023] However, since there are both small cars 17 and zebra crossings 18 in the highway service area, and there are a lot of them, and since large trucks 16 are required to drive in the outer lane according to traffic regulations, when large trucks 16 drive close to zebra crossings 18, the driver of small cars 17 in the inner lane will have their view blocked by large trucks 16, and will not be able to effectively observe the two-way warning display device, thus making it impossible to effectively determine whether there are pedestrians on zebra crossings 18.
[0024] like Figures 1-4 As shown, in order to solve the problem that the driver of a small car 17 located in the inner lane has an obstructed view and cannot effectively receive the two-way reminder display device, this technical solution discloses a two-way reminder display device for highway service area intersections, including a main pole 1. The main pole 1 is fixedly connected to a control host, a display screen 2, a signboard 3, a pedestrian sensing device 4, a flashing light 5, a supplementary light 6, an audio device 7, and a reminder light output device. The display screen 2, the pedestrian sensing device 4, the flashing light 5, the supplementary light 6, the audio device 7, and the reminder light output device are all electrically connected to the control host.
[0025] The main pole 1 is fixedly connected to one side of the road, providing a mounting base for the control host, display screen 2, signboard 3, pedestrian sensing device 4, strobe light 5, supplementary light 6, sound system 7, and warning light output device.
[0026] Among them, the pedestrian sensing device 4 can be a radar, a human body sensor or an AI camera. Its function is to identify whether there are pedestrians on the zebra crossing 18. Any device that can achieve the above functions can be a pedestrian sensing device 4.
[0027] Among them, the control host can be a microcontroller. When the pedestrian sensing device 4 detects a person on the zebra crossing 18, the control host can activate the display screen 2, strobe light 5, fill light 6, sound 7 and prompt light output device.
[0028] As an automatic shut-off method, when the pedestrian sensing device 4 detects that there is no one on the zebra crossing 18, the control host can automatically turn off the display screen 2, the flashing light 5, the supplementary light 6, the sound 7, and the warning light output device;
[0029] As another automatic shut-off method, after the pedestrian sensing device 4 activates the display screen 2, strobe light 5, supplementary light 6, sound 7 and warning light output device for a set duration of 30 seconds, the control host can automatically shut down the display screen 2, strobe light 5, supplementary light 6, sound 7 and warning light output device.
[0030] When the display screen 2 is activated, it can display a prompt message such as "Someone is crossing".
[0031] Among them, the strobe light 5 will emit flashing warning lights when activated to attract the driver's attention.
[0032] When the supplementary light 6 is activated, it will release illumination light to provide supplementary lighting.
[0033] When the speaker 7 is activated, it will play a warning voice message such as "Someone is crossing the road, please be careful".
[0034] The core of this technical solution lies in the warning light output device. When the warning light output device is activated, it releases warning light onto the road. The preferred color of the warning light is red. At this time, the warning light on the road acts as a non-physical "roadblock," allowing the driver of the small car 17 in the inner lane to effectively see the warning light, reducing the occurrence of situations where the driver of the small car 17 in the inner lane cannot effectively receive the warning from the two-way reminder display device due to obstructed vision.
[0035] The structure of one type of warning light output device is disclosed herein. The warning light output device includes multiple vertically arranged laser lights, which are horizontally set and can output multiple horizontal warning lights on the road.
[0036] Among them, such as Figure 2 As shown, another structure of a warning light output device is disclosed here. The warning light output device includes a lampshade 9 fixedly connected to one side of the main pole 1. A laser lamp 8 is fixedly connected to the lower end of the lampshade 9. Multiple light-emitting conduits 10 are fixedly connected to one side of the lampshade 9. At this time, the warning light is input into the lampshade 9 through the laser lamp 8 and then output through the multiple light-emitting conduits 10. Multiple warning lights are output to the road through one laser lamp 8.
[0037] Meanwhile, the interior of the lampshade 9 can also be fixedly connected with multiple semi-reflective lenses 11 that are one-to-one with the light-emitting guide tube 10. The semi-reflective lenses 11 can convert the vertical light output by the laser lamp 8 into horizontal light, thereby guiding the warning light output by the laser lamp 8 to the road, so that the warning light is projected laterally along the road.
[0038] The transmittance of multiple semi-reflective mirrors 11 can be different, that is, the transmittance of multiple semi-reflective mirrors 11 decreases in order from bottom to top.
[0039] like Figure 1 and Figures 3-4 As shown, the two-way warning display device also includes a secondary riser 12 fixedly connected to the road near the median guardrail 19. A secondary warning light cover 13 is fixedly connected to the secondary riser 12. The front end of the secondary warning light cover 13 is provided with multiple warning light output mechanisms. When the warning light output device is activated, the warning light output mechanism outputs warning light, thereby enabling the driver in the inner lane to be reminded through the warning light output mechanism located in front of the inner lane.
[0040] The indicator light output mechanism can be a laser light, or something similar. Figure 3 As shown, the warning light output mechanism is a light outlet 15. The auxiliary warning light cover 13 has a light inlet slot 14 on the side facing the light outlet guide tube 10. A light guide channel is formed between the light inlet slot 14 and the light outlet 15. At this time, the warning light output from the light outlet guide tube 10 shines into the light inlet slot 14. After being recovered by the light inlet slot 14, it is transmitted to the light outlet 15 through the light guide channel, and the warning light can be released through the light outlet 15. At this time, the warning light can be recovered by the light inlet slot 14, which can reduce the phenomenon of the warning light shining on the other lane.
[0041] Meanwhile, a light-transmitting protective sheet can be fixedly connected inside both the light-emitting hole 15 and the light-entry slot 14. The light-transmitting protective sheet is made of colorless glass, crystal or plastic, which can reduce the phenomenon of dust entering the light-entry slot 14 and the light-emitting hole 15.
[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
