[0002] With the continuous development of transportation, road safety issues have received increasing attention. Traditional road guardrails only have simple isolation and protection functions, which can no longer meet the higher requirements of modern transportation for intelligence and safety.

[0003] In the current traffic environment, traffic accidents frequently occur due to driver fatigue, speeding, and lack of timely and effective warnings for unexpected situations such as construction sites or accident areas ahead, causing serious casualties and property losses. At the same time, the complex and changeable road conditions and the uncertainty of vehicle driving status also bring huge challenges to traffic management.

[0004] In addition, some existing road warning facilities have problems such as single function, high energy consumption, and inability to interact effectively with vehicles, and cannot adapt to the development trend of intelligent traffic. In order to effectively solve these problems and improve the level of road traffic safety and traffic efficiency, it is urgent to develop a traffic warning metal road guardrail device with intelligent detection, early warning and interactive functions, energy saving, environmental protection, stability and reliability. The present invention came into being in this context, aiming to provide innovative solutions for road traffic safety and intelligent traffic management. Summary of the invention

[0017] When the driver of the vehicle ahead is detected to be driving fatigued, the controller controls the warning light assembly on the side of the vehicle to display yellow;

[0018] When construction is detected ahead, the controller controls the warning light assembly 200 meters ahead of the construction area to display orange;

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the invention.

[0053] Please refer to the instruction manual Figure 1-Figure 4 , the present invention provides a specific implementation of an intelligent traffic warning metal road guardrail device and a control method thereof:

[0054] Device part:

[0055] The intelligent traffic warning metal road guardrail device comprises a metal guardrail body 1 , and is also provided with a warning light component 2 , a sensor component 3 , a controller 4 , a power supply component 5 , a communication module 7 and a positioning module 8 .

[0056] The warning light assembly 2 includes a plurality of intelligent color-changing warning lights 21 evenly distributed along the length direction of the metal guardrail body 1. These intelligent color-changing warning lights 21 can display light signals of different colors and brightness according to the instructions of the controller 4, such as lamp beads of various colors.

[0057] The sensor assembly 3 includes a road condition detection sensor 31 and a vehicle state detection sensor 32. The road condition detection sensor 31 can detect and receive real-time road condition information, such as road condition, road flatness, whether there are obstacles, traffic flow, vehicle density, weather conditions, rain, snow, fog, clear, etc., including but not limited to road condition sensors, meteorological sensors, traffic flow sensors, etc.; the vehicle state detection sensor 32 can be interconnected with the built-in fatigue monitor of the intelligent new energy vehicle or other sensors for detecting the vehicle state to obtain the vehicle's driving state information, such as vehicle speed, vehicle distance, driver fatigue state, etc., and the sensor is a sensor that can communicate wirelessly with the intelligent new energy vehicle.

[0058] The controller 4 is connected to the warning light assembly 2, the sensor assembly 3, the communication module 7 and the positioning module 8 respectively. It is a controller with intelligent analysis and decision-making capabilities. The algorithm preset in the controller 4 is as follows:

[0059] Fatigue driving judgment algorithm: The vehicle state detection sensor 32 is used to obtain vehicle driving data, such as whether the vehicle's driving trajectory deviates frequently, the driver's blinking frequency, head movements, etc. When these data exceed the preset normal range, it is judged that the driver is driving fatigued.

[0060] Speeding judgment algorithm: Combined with the road condition information such as the road speed limit provided by the road condition detection sensor 31 and the vehicle speed information obtained by the vehicle state detection sensor 32, when the vehicle speed exceeds a certain proportion of the road speed limit, it is judged that the vehicle is speeding.

[0061] Construction or traffic accident area judgment algorithm: The position information of the guardrail device is obtained through the positioning module 8, combined with the preset position information of the construction or traffic accident area. When the distance between the guardrail device and the construction or traffic accident area is within a certain range, it is judged to be close to the construction or traffic accident area.

[0062] According to the above algorithm analysis, it is determined whether there is an abnormality in the driving state of the vehicle, such as driver fatigue driving, vehicle speeding, etc., and whether it is close to the construction or traffic accident area, and the working state and display color of the warning light assembly 2 are controlled accordingly. For example, when it is detected that the driver of the front vehicle is driving fatigued, the controller 4 controls the warning light assembly 2 on the side of the vehicle to display yellow; when it is detected that there is construction ahead, the controller 4 controls the warning light assembly 2 200 meters in front of the construction area to display orange; when it is detected that there is a traffic accident ahead, the controller 4 controls the warning light assembly 2 200 meters in front of the traffic accident area to display red.

[0063] The power supply component 5 includes a solar panel 51, a battery 52 and a power management module 53. The solar panel 51 is used to convert solar energy into electrical energy, the battery 52 is used to store electrical energy, and the power management module 53 is used to manage and optimize the power supply of the entire device to ensure the stable operation of each component. When there is sufficient sunlight during the day, the solar panel 51 converts solar energy into electrical energy and charges the battery 52 through the power management module 53, while providing power to the warning light component 2, the sensor component 3, the controller 4, the communication module 7 and the positioning module 8. When there is insufficient sunlight at night or on cloudy days, the battery 52 supplies power to each component through the power management module 53.

[0064] The surface of the metal guardrail body 1 is provided with an anti-corrosion coating to improve its corrosion resistance. The anti-corrosion coating is made of a material with good corrosion resistance and wear resistance, which can effectively extend the service life of the metal guardrail body 1.

[0065] A fixed base 6 is provided at the bottom of the metal guardrail body 1, and the fixed base 6 is fixedly connected to the ground by anchor bolts to improve the stability of the metal guardrail body 1. The fixed base 6 is made of high-strength steel and has sufficient bearing capacity and impact resistance, which can ensure that the metal guardrail body 1 will not easily fall or be damaged when subjected to external forces such as vehicle collisions.

[0066] Control method part:

[0067] First, the sensor assembly 3 detects the road condition information and the vehicle status information in real time, and sends the detected information to the controller 4. At the same time, the positioning module 8 obtains the position information of the guardrail device in real time and sends it to the controller 4.

[0068] Then, the controller 4 uses a preset algorithm to analyze and process the received information to determine whether the vehicle's driving state is abnormal and whether it is close to a construction or accident area.

[0069] If there is an abnormality in the driving state of the vehicle, such as detecting fatigue driving of the driver of the preceding vehicle through the fatigue driving judgment algorithm, the controller 4 controls the warning light assembly 2 on the side of the vehicle to turn yellow, alerting the driver in the vehicle and reminding the drivers of surrounding vehicles at the same time.

[0070] If construction ahead is detected through the construction or accident area judgment algorithm, the controller 4 controls the warning light assembly 2 200 meters ahead of the construction area to turn orange to issue an early warning prompt.

[0071] If a traffic accident is detected ahead, the controller 4 controls the warning light assembly 2 200 meters ahead of the traffic accident area to turn red to issue an early warning prompt.

[0072] Finally, the controller 4 feeds back the road condition information, vehicle status information, location information and working status of the guardrail device to the intelligent new energy vehicle in real time through the communication module 7, so as to realize vehicle-road cooperative interaction. After receiving this information, the intelligent new energy vehicle can adjust the driving strategy according to the actual situation, such as deceleration, avoidance, etc., so as to improve driving safety and traffic efficiency.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0074] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
