Description

Technical Field

[0001] This utility model relates to the field of highway technology, and in particular to an integrated warning light for highways. Background Technology

[0002] Highway warning lights are lights installed on highways to warn drivers and ensure driving safety. Integrated highway warning lights are devices that integrate multiple warning functions into one unit. They are needed because of their significant advantages in terms of functional integration, improved warning effect, and ease of maintenance and management.

[0003] Following a traffic accident on the highway, relevant equipment was quickly activated. LED displays immediately switched to show accident information, and strobe lights were rapidly placed around the accident scene and at key locations ahead. Their intense flashing lights were particularly conspicuous in the night, alerting vehicles in the distance to slow down and avoid the area. Subsequently, horns were used to sound sirens, thereby alerting vehicles on the highway.

[0004] In existing technologies, some highway warning devices are separate units, such as flashing lights, directional broadcasts, and LED variable message signs, each operating independently. This results in a lack of real-time synchronization of information transmission. For example, if the flashing lights activate before the LED variable message signs, drivers may not immediately obtain specific accident information from the LED signs after seeing the flashing lights. This creates a gap in information acquisition, affecting accurate judgment of road conditions and increasing safety risks. Therefore, to address these shortcomings, an integrated highway warning light is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an integrated highway warning light, which aims to improve the problem that some existing highway warning devices are independent units, unable to obtain all information in a timely manner, reducing the judgment efficiency of vehicle personnel and thus reducing safety.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] An amplifier is fixedly connected to the top front side of the warning frame, a voice prompt board is fixedly connected to the middle front side of the warning frame, and an optical transceiver is fixedly connected to the bottom front side of the warning frame.

[0012] As a further description of the above technical solution:

[0013] Both sliding components include a sliding plate, and the two sliding plates are slidably connected to the top left and right ends of the warning frame, respectively. A fixing plate is fixedly connected to the adjacent side of each of the two sliding plates.

[0014] As a further description of the above technical solution:

[0015] The two fixed plates are slidably connected to the left and right sides of the two force-bearing plates respectively on their adjacent sides, and the exterior of the two limiting blocks are slidably connected to the interior of the front and rear ends of the connecting plate respectively.

[0021] The near ends of the multiple springs are respectively fixedly connected to the far sides of the multiple connecting blocks, and the outer sides of the two force plates are respectively slidably connected to the front and rear ends of the top of the warning frame.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of an integrated highway warning light, comprising a warning frame 1 and a horn 4. The warning frame 1 is rectangular. An LED display 2 is fixedly connected to the front end of the warning frame 1. This LED switchable text display uses double rows of LEDs for each Chinese character stroke. In the red light state, the LED displays "Stop Ahead"; in the green light state, the LED displays "Proceed Slowly." It complies with the relevant technical requirements in the "National Standard of the People's Republic of China GB / T23828—2023 Highway LED Variable Message Signs." The LED switchable text display has three working states: silent black screen, red text, and green text.

[0035] A power amplifier 6 is fixedly connected to the top front of the warning frame 1. The power amplifier 6 has a power output of at least 300W for the alarm sound, and its dimensions are controlled within 500mm x 180mm. An 8Ω impedance speaker, matching the 300W power amplifier 6, is installed on the top of the enclosure. This power amplifier 6 is connected to a 485 control box via a voice prompt board, providing three sound states: a. Normal state: silent; b. During an incident: siren / fire alarm + "Accident ahead, do not proceed"; c. After the incident is resolved: "Accident resolved, proceed slowly." These states are switched remotely via a 485 control by a PLC, which also provides feedback on the equipment's operating status. In operating state b, the voice prompt board has multiple built-in sounds available for selection by the mini-program, such as siren + "Accident ahead, do not proceed," "Accident ahead, slow down," and "Accident ahead, do not proceed." This amplifier 6 features high power output and low distortion, which can amplify audio signals to a sufficient volume to ensure that the sound emitted by speaker 4 is clearly audible in noisy highway environments, and meets the sound pressure level technical requirements of the draft national standard "Technical Specifications for Road Traffic Directional Broadcast Warning System" (project number 20230345-T-312).

[0036] A voice prompt board 7 is fixedly connected to the front center of the warning frame 1. The voice prompt board 7 can store a variety of pre-recorded voice messages, such as "Construction ahead, please slow down" and "Icy road, please be careful," which are played through the speaker 4. A PLC control box 8 is fixedly connected to the front center of the warning frame 1. The PLC control box 8 is the control core of the entire warning light and can realize intelligent control of components such as LED display 2, strobe light 3, and speaker 4. It can automatically switch the display content and warning mode according to different road conditions and time conditions. An optical transceiver 9 is fixedly connected to the front bottom of the warning frame 1. The optical transceiver 9 is used to realize long-distance data transmission. It can transmit information such as the working status of the warning light to the monitoring center, and can also receive control commands from the monitoring center to realize remote monitoring and management.

[0037] The bottom side of the warning frame 1 is fixedly connected to a connecting assembly for use with road bollards. A support plate 22 is slidably connected to the rear end of the warning frame 1, providing additional support and stability. Multiple connecting plates 5 are fixedly connected to the rear side of the support plate 22, joined by welding to form a single unit. The front sides of the multiple connecting plates 5 are respectively fixed to the four rear corners of the warning frame 1 with screws, allowing the warning frame 1 to form a single unit with the support plate 22. The connecting assembly includes a base plate 10, the top side of which is fixedly connected to the bottom side of the warning frame 1. The base plate 10 is made of thick metal sheet and is tightly connected to the warning frame 1 by welding to ensure a strong connection. An obtuse angle plate 11 is fixedly connected to the bottom side of the base plate 10 by multiple screws. The obtuse angle plate 11 can fit tightly against the surface of the road bollard, and the screw fixing method facilitates installation and adjustment.

[0038] Reference Figures 4 to 6 A trapezoidal plate 12 is fixedly connected to the bottom side of the horn 4, providing stable support for the horn 4. A connecting plate 13 is fixedly connected to the bottom side of the trapezoidal plate 12, and the trapezoidal plate 12 and the connecting plate 13 are connected by welding to form a whole. The outer side of the connecting plate 13 is slidably connected to the inside of the top of the warning frame 1. The limiting effect of the warning frame 1 allows the connecting plate 13 to slide stably. Sliding components for transmitting power are slidably connected to the top left and right ends of the warning frame 1. The sliding components can fix the connecting plate 13, thereby fixing the horn 4. Each of the two sliding components includes a sliding plate 14. The outer sides of the two sliding plates 14 are slidably connected to the top left and right ends of the warning frame 1, respectively. The limiting effect of the warning frame 1 allows the sliding plates 14 to slide stably. A fixing plate 15 is fixedly connected to the adjacent side of the two sliding plates 14. Pressing the sliding plate 14 causes the fixing plate 15 to slide synchronously. Two square openings 16 are provided at the top front and rear ends of the warning box 1. Two force plates 17 are slidably connected to the adjacent side of the two sliding components to withstand the thrust of the fixed plate 15.

[0039] Two fixed plates 15 are slidably connected to the left and right sides of two force-bearing plates 17 on their adjacent sides, allowing the fixed plates 15 to transfer the left and right sliding force to the force-bearing plates 17 and convert it into a forward and backward sliding force. The outer sides of the two force-bearing plates 17 are slidably connected to the front and rear ends of the top of the warning frame 1, allowing the force-bearing plates 17 to slide stably due to the constraint of the warning frame 1. Connecting blocks 18 are fixedly connected to the upper and lower sides of each force-bearing plate 17, causing the connecting blocks 18 to slide synchronously. A support rod 19 is slidably connected inside each connecting block 18, providing guidance for the sliding of the connecting block 18. A spring 20 is sleeved on the outside of the support rod 19, allowing the spring 20 to be evenly stressed by the constraint. The adjacent ends of multiple springs 20 are fixedly connected to the distant sides of multiple connecting blocks 18. The sliding of the connecting blocks 18 compresses the springs 20, allowing the springs 20 to store elastic potential energy, which then applies a force in the opposite direction to the connecting blocks 18 for resetting. Limiting blocks 21 are fixedly connected to adjacent sides of the two load-bearing plates 17. The limiting blocks 21 can limit and fix the connecting plate 13. The exterior of the two limiting blocks 21 is slidably connected to the interior of the front and rear ends of the connecting plate 13, respectively. The limiting blocks 21 can fit tightly with the connecting plate 13, thereby improving the fixing effect.

[0040] Working principle: First, align the obtuse angle plate 11 at the bottom of the base plate 10 with the road stone block, and use screws to fix the obtuse angle plate 11 to the stone block. Then connect the communication line of the optical transceiver 9 to establish a data connection with the monitoring center;

[0041] Subsequently, control commands are sent to the warning lights via a remote PLC. When the road is open to traffic, the PLC controls LED display 2 to remain in a silent black screen state, power amplifier 6 remains silent, and strobe light 3 is turned off.

[0042] In the event of an accident, the PLC controls the LED display 2 to show the corresponding warning text (such as "Stop ahead" when the light is red), and at the same time controls the power amplifier 6 to switch to the audio state at the time of the accident, playing the siren and the voice message "Accident ahead, no passage", and the flashing lights 3 are turned on to warn passing vehicles with a strong sound and light signal.

[0043] At this time, if the speaker 4 needs to be inspected or maintained, by pressing the sliding plate 14, the fixing plate 15 is pushed to slide, thereby squeezing the two force plates 17 to slide to the opposite side. At the same time, the connecting block 18 will also slide and squeeze the spring 20, so that the spring 20 can store elastic potential energy, and then give the connecting block 18 a force in the opposite direction to the force plate 17 to reset. When the two force plates 17 slide to the opposite side, the limiting block 21 will also slide and slide away from the inside of the connecting plate 13. At this time, the speaker 4 can be quickly removed. Conversely, after the operation is completed, the sliding plate 14 is released, the spring 20 pushes the connecting block 18 and the force plate 17 to reset, so that the limiting block 21 re-fixes the connecting plate 13, and then the installation of the speaker 4 is quickly completed, thereby improving the efficiency of disassembly and assembly.

[0044] After the incident was resolved, the monitoring center controlled the warning lights again via PLC, switching LED display 2 to the green light state to display "Slow Passage", the power amplifier 6 played the voice message "Accident resolved, slow passage", the strobe light 3 was turned off, and the normal traffic indication state was restored.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
