Technical Field

[0001] The present invention relates to the technical field of traffic safety equipment, and particularly to an automatic warning and isolation robot for sudden accidents on expressways. Background Art

[0002] On expressways, the occurrence of sudden accidents often has a serious impact on traffic. At present, the warning and isolation at the accident scene mainly rely on manually placing warning signs and setting up isolation facilities, and this method has many drawbacks. On the one hand, the manual operation efficiency is low, and it takes a long time from the occurrence of the accident to the completion of the warning and isolation measures, during which secondary accidents are extremely likely to occur; on the other hand, the vehicle speed is fast and the traffic flow is large on expressways, and manual operation on the site faces great safety risks.

[0007] Further, the height-adjusting mechanism includes a cross bar, the top of the cross bar is provided with an electric telescopic rod, and the output end of the electric telescopic rod is fixedly connected with the bottom end of the lifting plate.

[0008] The beneficial effect of adopting the above further scheme is that by fixedly connecting the output end of the electric telescopic rod with the bottom end of the lifting plate, the height of the lifting plate can be adjusted, and the shooting range of the first camera is improved.

[0009] Further, a lithium battery is installed at the bottom end inside the barrel body, a charging interface is installed on one end face of the charging seat, and the charging interface is electrically connected with the lithium battery through a wire.

[0010] The beneficial effect of adopting the above further scheme is that a lithium battery is installed at the bottom end of the barrel to provide power for the operation of the robot, and a charging interface is installed on one end face of the charging base, which facilitates the robot to automatically return to its position to charge the lithium battery, ensuring that the robot can continue to work without frequent battery replacement, thereby improving convenience of use.

[0011] Furthermore, a plurality of reflective stickers are pasted on the outer side of the barrel.

[0012] The beneficial effect of adopting the above further scheme is that by sticking a number of reflective stickers on the outside of the barrel, it can reflect light under light exposure, making it easier for passing vehicles to notice the robot even at night or in bad weather conditions, thereby enhancing the warning effect.

[0013] Furthermore, a second camera, a laser radar and an LED lighting lamp are installed on one end surface of the control box, and a warning light is installed on the top of the control box.

[0014] The beneficial effect of adopting the above further scheme is that, through the setting of the second camera and the laser radar, the collection of surrounding environment information can be further supplemented, and the robot's perception of road conditions and accident scenes can be improved. Through the setting of LED lighting, the surrounding environment can be illuminated when the light is insufficient, which facilitates the normal operation of the equipment. A warning light is installed on the top of the control box to clearly remind passing vehicles to pay attention to the accident ahead.

[0015] Furthermore, a controller and a GPS locator are installed inside the control box.

[0016] The beneficial effect of adopting the above further scheme is that through the setting of the controller, it is used to control the operation of various components of the robot and coordinate the work of each part.

[0019] In another aspect, the present invention provides a method for using a highway accident automatic warning isolation robot, comprising the following steps:

[0020] S1, Accident Response and Automatic Deployment: When an accident occurs on the highway, the management system sends a start command to the robot. After receiving the command, 20 robots automatically set out. The controller in the control box obtains its own position by combining the built-in program and the accident location information received, and uses the GPS locator. It scans and monitors the surrounding environment with the second camera and lidar, plans the optimal moving route to the accident scene, and the motor drives the walking wheels to make the robot quickly drive towards the accident scene along the planned route. During the driving process, the robot continuously senses the surrounding environment through the second camera and lidar, adjusts the moving direction in real time, avoids obstacles, and ensures driving safety. After reaching the designated position at the accident scene, the robots are arranged along a 1-kilometer curved path to form an isolation belt. At this time, the height adjustment mechanism starts to work, the electric telescopic rod extends, and pushes the lifting plate to rise, so that the first camera and the laser rangefinder reach a suitable height to better monitor the accident scene and the surrounding environment;

[0021] S2, On-site Monitoring and Warning Guidance: The first camera takes all-round real-time pictures of the accident scene and transmits the image information to the controller in the control box. The controller analyzes and processes the received images, identifies the situation at the accident scene, such as the damage condition of the vehicle and the casualty situation of the personnel, and sends the relevant information to the management system and the cooperating drones through the wireless signal transceiver. At the same time, the laser rangefinder measures the distance of surrounding objects in real time to assist the first camera to more accurately sense the on-site environment. The LED lighting lamp automatically turns on at night or in low-light conditions to provide lighting for on-site monitoring, and the warning lamp starts to flash. The reflective stickers on the outside of the barrel also enhance the warning effect to guide the following vehicles to pay attention to avoidance. The second camera is used to monitor the situation in the close vicinity around the robot to further ensure its own and surrounding safety;

[0022] S3, Cooperative Operation and Dynamic Adjustment: The drones cooperating with the robot use cameras and GPS to comprehensively monitor the accident scene and the surrounding traffic conditions. The drones transmit data such as the location of the accident vehicle, the situation of the following vehicles, and the traffic flow in real time to the robot. After receiving the data transmitted by the drones, the controller combines the information it monitors itself and dynamically adjusts the warning isolation strategy. If the speed of the following vehicle is too fast or the distance is too close, with the assistance of the drone, the robot replans the moving route through the lidar and the first camera to avoid colliding with the following vehicle. At the same time, according to the traffic flow situation, the robots communicate with each other through the wireless signal transceiver, adjust their positions and distances from each other, and optimize the layout of the isolation belt to ensure that vehicles can detour safely and smoothly;

[0023] S4, Intelligent Detection and Maintenance: During operation, the robot's controller will perform real-time self-checks on its own hardware and software for faults. If a fault is detected, the controller will immediately send a fault alert to the management system via the wireless signal transceiver, reporting the type and location information of the fault so that the staff can carry out repairs in a timely manner. When the robot completes a task or its battery level is low, the controller plans a route back to the starting point based on the information from the GPS locator. The robot automatically returns along the planned route and, upon reaching the starting point, the charging interface on the charging dock docks with the charging facility to start charging the lithium battery, getting ready for the next task.

[0039] See also Figure 6 The present invention provides a technical solution: a method for using a highway emergency automatic warning isolation robot, comprising the following steps:

[0040] S1, Accident Response and Automatic Deployment: When an accident occurs on the highway, the management system sends a startup instruction to the robot. After receiving the instruction, 20 robots automatically set out. The controller in the control box 105 obtains its own position by combining the built-in program and the received accident location information with the GPS locator, and uses the second camera 10501 and the lidar 10502 to scan and monitor the surrounding environment, planning the optimal moving route to the accident scene. The motor 102 drives the walking wheels 103, enabling the robot to quickly drive towards the accident scene along the planned route. During the driving process, the robot continuously senses the surrounding environment through the second camera 10501 and the lidar 10502, adjusts the moving direction in real time, avoids obstacles, and ensures driving safety. After reaching the designated position at the accident scene, the robots are arranged along a 1-kilometer curved path to form an isolation belt. At this time, the height adjustment mechanism 110 starts to work, the electric telescopic rod 11002 extends, pushing the lifting plate 107 upward, so that the first camera 109 and the laser rangefinder 112 reach an appropriate height for better monitoring of the accident scene and the surrounding environment;

[0041] S2, On-site Monitoring and Warning Guidance: The first camera 109 takes all-round real-time pictures of the accident scene and transmits the image information to the controller in the control box 105. The controller analyzes and processes the received images, identifies the situation at the accident scene, such as the damage condition of the vehicle and the casualty situation, and sends the relevant information to the management system and the cooperating drones through the wireless signal transceiver 10506. At the same time, the laser rangefinder 112 measures the distance to surrounding objects in real time to assist the first camera 109 to more accurately sense the on-site environment. The LED lighting lamp 10503 automatically turns on at night or in low-light conditions to provide lighting for on-site monitoring, and the warning lamp 10504 starts to flash. The reflective sticker 10401 on the outer side of the barrel 104 also enhances the warning effect, guiding the following vehicles to pay attention to avoidance. The second camera 10501 is used to monitor the situation in the close vicinity around the robot to further ensure its own and surrounding safety;

[0042] S3, Cooperative Operation and Dynamic Adjustment: The drones cooperating with the robot use cameras and GPS to comprehensively monitor the accident scene and the surrounding traffic conditions. The drones transmit data such as the location of the accident vehicle, the situation of the following vehicles, and the traffic flow located in real time to the robot. After receiving the data transmitted by the drones, the controller combines the information it monitors itself and makes dynamic adjustments to the warning isolation strategy. If the speed of the following vehicle is too fast or the distance is too close, with the assistance of the drones, the robot replans the moving path through the lidar 10502 and the first camera 109 to avoid collision with the following vehicle. At the same time, according to the traffic flow situation, the robots communicate with each other through the wireless signal transceiver 10506, adjust their positions and spacings from each other, and optimize the layout of the isolation belt to ensure that vehicles can detour safely and smoothly;

[0043] S4, Intelligent Detection and Maintenance: During operation, the robot's controller will conduct real-time self-checks on its own hardware and software for faults to determine if there are any malfunctions. If a fault is detected, the controller immediately sends a fault alert to the management system via the wireless signal transceiver 10506, reporting the type and location information of the fault so that the staff can perform repairs in a timely manner. When the robot completes its task or its battery level is low, the controller plans a route back to the starting point based on the information from the GPS locator. The robot automatically returns along the planned route. After arriving at the starting point, the charging interface 10601 on the charging dock 106 docks with the charging facility to start charging the lithium battery 111 in preparation for the next task.

[0044] Specifically, the working principle of the automatic warning and isolation robot for sudden accidents on highways is as follows: when in use, a walking wheel 103 is installed at the output end of the motor 102 to realize the movement of the robot, so that the robot can quickly reach the accident site on the highway and carry out warning and isolation work in time.

A charging interface 10601 is installed at one end of the charging seat 106 to facilitate the robot to automatically return to its position to charge the lithium battery, thereby ensuring that the robot can continue to work without frequent battery replacement, thereby improving the convenience of use. A number of reflective stickers 10401 are attached to the outer side of the barrel 104 to reflect light under light exposure, so that passers-by can see it even at night or in bad weather conditions. The vehicle is more likely to notice the robot, which enhances the warning effect. The second camera 10501 and the laser radar 10502 are set to further supplement the collection of surrounding environment information and improve the robot's perception of road conditions and accident scenes.

The drones transmit data such as the position of the accident vehicle located, the situation of the oncoming vehicles behind, and the traffic flow in real time to the robot. After receiving the data transmitted by the drones, the controller combines the information it monitors itself to dynamically adjust the warning isolation strategy. If the speed of the oncoming vehicle behind is too fast or the distance is too close, with the assistance of the drones, the robot replans the moving path through the lidar (10502) and the first camera (109) to avoid colliding with the oncoming vehicle behind. At the same time, according to the traffic flow situation, the robots communicate with each other through the wireless signal transceiver (10506) to adjust their positions and spacings from each other, optimizing the layout of the isolation belt to ensure that vehicles can detour safely and smoothly; S4, Intelligent Detection and Maintenance: During operation, the robot's controller will perform real-time self-checks on its own hardware and software for faults to determine if there are any malfunctions. If a fault is detected, the controller immediately sends a fault alert to the management system via the wireless signal transceiver (10506), reporting the type and location information of the fault so that the staff can carry out repairs in a timely manner. When the robot completes its task or its battery level is low, the controller plans a route back to the starting point based on the information from the GPS locator. The robot automatically returns along the planned route and, upon arrival at the starting point, the charging interface (10601) on the charging dock (106) docks with the charging facility to start charging the lithium battery (111) in preparation for the next task.
