[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0022] In this embodiment, a rotatable intelligent traffic warning device is provided, including a flashing warning light 1, a loudspeaker 2, a guidance display screen 3, a rotatable main body, a static road traffic sign 7, and a controller. The guidance display screen 3 and the static road traffic sign 7 are respectively arranged on the front and rear opposite sides of the rotatable main body. The flashing warning light 1 and the loudspeaker 2 are arranged on the surface of the rotatable main body above the guidance display screen 3. The controller is located inside the rotatable main body, and the strobe warning light 1, the loudspeaker 2, the guidance display screen 3, and the rotation motor driver of the rotatable main body are all connected to the controller. The guidance display screen 3 can display different dynamic guidance signs.
[0023] like Figure 1As shown, specifically, the rotatable body includes a box body 4, a column 5, and a rotating mechanism 6. The lower end of the box body 4 is connected to the upper end of the column 5, and the lower end of the column 5 is connected to the output end of the rotating mechanism 6. The rotating mechanism 6 drives the column 5 to rotate, thereby driving the box body 4 to rotate. The guidance display screen 3 and the static road traffic sign 7 are respectively arranged on the front and rear opposite sides of the box body 4. The surface of the box body 4 on the upper side of the guidance display screen 3 is provided with a flashing warning light 1 and a broadcast speaker 2. The controller is located inside the box body 4, and the rotary motor driver of the rotating mechanism 6 is electrically connected to the controller.
[0024] like Figure 2 As shown, specifically, the controller includes a microcontroller and connected to it a power module, a 433 wireless communication module, a GPS / BeiDou module, a 4G communication device, a network communication module, an LED driver module, an I / O output module, an audio driver module, and a serial communication module. The 433 wireless communication module, GPS / BeiDou module, and 4G communication device are all connected to an antenna. The LED driver module is connected to the guidance display screen 3. The I / O output module is connected to the strobe warning light 1. The audio driver module is connected to the loudspeaker 2. The serial communication module is connected to the rotary motor driver of the rotating mechanism 6. The relevant communication modules seamlessly connect to third-party monitoring equipment such as natural disaster monitoring facilities and traffic radar through the antenna to obtain relevant information and automatically rotate and switch between different guidance modes to provide early warnings for vehicles.
[0025] The power module supplies power to the microcontroller, which controls relevant components through corresponding function modules to achieve their respective functions. The LED driver module controls the guidance display screen 3 to display different dynamic guidance signs. When displaying dynamic guidance signs, the microcontroller also controls the flashing warning light 1 and the broadcast speaker 2 to emit a voice announcement through the IO output module and / or audio driver module, thus providing a warning to the vehicle. The microcontroller obtains local latitude, longitude, and time information in real time through the GPS / BeiDou module to provide warnings in appropriate scenarios. The microcontroller supports wireless self-organizing networks through a 433M wireless communication module, enabling local wireless communication between devices and ensuring timely transmission of warning information. The controller supports both wired and wireless 4G communication methods to ensure stable communication.
[0026] like Figure 3 and Figure 4 As shown, the static road traffic sign 7 includes two different styles; the first type of static road traffic sign 7 includes a warning sign 8 and a prompt sign 9, used to warn vehicles and pedestrians to pay attention to road traffic. The second type of static road traffic sign 7 includes a prohibitory sign 10 and a prompt sign 9, used to prohibit or restrict the traffic behavior of vehicles and pedestrians. The two types of static road traffic signs 7 can be selected and adjusted according to their placement.
[0027] In this embodiment, two strobe warning lights 1 are horizontally spaced on the surface of the main body 4 on the upper side of the guidance display screen 3, and the loudspeaker 2 is positioned between the two strobe warning lights 1. The two strobe warning lights 1 can flash different colors when in operation, thereby alerting the driver. The number of loudspeakers 2 can be adjusted according to actual needs to better meet practical requirements. The combination of the strobe warning lights 1 and the loudspeakers 2 attracts the driver's attention through both visual and auditory means, effectively avoiding warning failure due to fatigue of a single sensory organ or distraction.
[0028] In this embodiment, the rotatable intelligent traffic warning device supports multiple dynamic warning methods, such as... Figure 5 As shown, natural disaster monitoring facilities monitor disaster-prone road sections in real time, and early warning devices formulate corresponding guidance plans based on different disaster events, controlling the guidance facilities to issue warnings to passing vehicles; such as Figure 6 As shown, traffic radar monitors vehicle events in real time, and the early warning device configures corresponding guidance schemes based on different traffic events, controlling the guidance facilities to issue early warnings to passing vehicles; for example... Figure 6 As shown, the early warning device has a built-in GPS / BeiDou module, which obtains local latitude, longitude, and time information in real time, automatically calculates the sunset / sunrise time of the day, and automatically controls the guidance facilities to issue early warnings to passing vehicles based on the sunset / sunrise time and a set offset, thereby improving nighttime traffic capacity; for example, Figure 7 As shown, based on local road conditions, such as the time period when traffic is prone to congestion or the different traffic flow at different times according to big data statistics, corresponding guidance schemes are set, and the warning device automatically guides traffic according to the time nodes.
[0029] In this embodiment, the device integrates static and dynamic guidance functions, automatically switching between normal and interrupted road traffic to warn and guide vehicles. By incorporating a guidance display screen 3, a flashing warning light 1, and a loudspeaker 2, the device offers multiple guidance methods, including information dissemination, flashing warnings, and voice reminders, and can customize corresponding guidance strategies based on different events. Through a sophisticated mechanical structure and controller, the device achieves a 180-degree rotation of the traffic sign, thus enabling dynamic sign transformation. This design cleverly combines the stability of static signs with the flexibility of dynamic signs, retaining the advantages of low cost and simple maintenance of static signs while possessing the ability to update dynamic sign information in real time.
[0030] The device adopts a double-sided design, including a static traffic sign surface and a dynamic guidance sign surface. Under normal circumstances, the static traffic sign surface (static traffic sign 7) faces the direction of travel, displaying warning sign 8 / prohibition sign 10 and prompt sign 9; when the road is interrupted, the dynamic guidance sign surface (guidance display screen 3) turns to the direction of travel, providing dynamic information display, flashing warning and voice prompt.
[0031] By adopting the above-disclosed technical solution of this utility model, the following beneficial effects are obtained:
[0032] This invention provides a rotatable intelligent traffic warning device, improving the real-time performance and accuracy of traffic guidance systems. It ensures rapid and precise adjustment of warning information when road conditions change, effectively guiding vehicles to pass safely. Simultaneously, it enhances the intelligence level of traffic management, achieving automated switching and remote monitoring of guidance signs based on wireless self-organizing networks and remote control technology, significantly reducing reliance on manual intervention.
