Description

Technical Field

[0001] This invention belongs to the field of traffic equipment technology and relates to a road traffic accident warning device deployment system and method based on air-ground coordination. Background Technology

[0002] During vehicle operation, traffic accidents are easily caused by factors such as driver violations, cognitive and judgment errors, distracted driving, vehicle brake failure, sharp turns, insufficient visibility, or bad weather. When vehicles behind fail to slow down in time or do not see the obvious warning signals of the accident vehicle, chain collisions are likely to occur, seriously endangering road safety.

[0003] When a road traffic accident occurs, the vehicle's hazard lights are usually turned on and a warning triangle is placed at a certain distance behind the vehicle. However, in busy traffic sections, at night, or in adverse weather conditions such as heavy rain or fog, the existing measures are generally ineffective in warning and fail to guide traffic, which is detrimental to the personal safety of car owners and the smooth flow of traffic. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a road traffic accident warning device deployment system and method based on air-ground coordination. This system and method can promptly deploy warning devices around the accident vehicle after a traffic accident to alert vehicles behind and ensure safe passage on the road.

[0005] To achieve the above objectives, the present invention discloses a road traffic accident warning device deployment system based on air-ground collaboration, including a warning device deployment vehicle, an unmanned transport container, and an interactive decision-making system. The interactive decision-making system is connected to the warning device deployment vehicle and the unmanned transport container. The unmanned transport container includes a drone and a transport container suspended below the drone and located between the drone's landing gear. The warning device deployment vehicle is located inside the transport container.

[0006] Furthermore, the warning device deployment vehicle includes an equipment box for storing cones and a power box located at the bottom of the equipment box for providing power. Multiple sets of wheels are connected to the bottom of the power box. Several latches for fixing the cones are evenly distributed inside the bottom of the equipment box. A first rotating shaft is connected to the top of the equipment box, and a first warning light is installed on the top of the first rotating shaft. The rear of the equipment box is connected to the gantry via a first telescopic rod and a second telescopic rod to drive the gantry to move back and forth. A slider is suspended below the second telescopic rod, and a gripper is connected to the bottom of the slider to grasp or release the cones.

[0007] Furthermore, outline lights are installed at the front of the equipment box and on both sides of the top of the mast to alert vehicles approaching from behind.

[0008] Furthermore, a camera is installed in both the equipment box and the gantry.

[0009] Furthermore, the top of the cone is equipped with a flashing No. 4 warning light.

[0010] Furthermore, each side of the transport container is equipped with a No. 3 rotating shaft, which is connected to an extension rod. The extension rod is equipped with a No. 3 warning light and a No. 3 camera. The extension rod, the No. 3 warning light, and the No. 3 camera can move in a circle around the No. 3 rotating shaft. When the drone is in the air, the No. 3 camera and the No. 3 rotating shaft are controlled to rotate, enabling all-round observation of the surrounding environment. When the drone lands, the No. 3 rotating shaft retracts the No. 3 camera to the inside of the landing gear in time through rotation. At the rear of the transport container, a pair of doors are connected to the No. 2 rotating shaft. The No. 2 rotating shaft controls the opening and closing of the doors through rotation.

[0011] Furthermore, a pair of positioning grooves for fixing wheels are provided on the inner side of the bottom of the transport container.

[0012] Furthermore, the drone is equipped with a second warning light and a second camera on its top.

[0013] Furthermore, the drone is equipped with a second warning light and a second camera on its top.

[0014] This invention discloses a method for deploying road traffic accident warning devices based on air-ground cooperation, and a system for deploying road traffic accident warning devices based on air-ground cooperation, comprising the following steps: 1) The drone flies to the accident site based on the coordinates, observes the surrounding environment through the camera, analyzes and accurately locates the accident vehicle, and plans the operation path of the warning device deployment vehicle and the placement position of the cones. 2) The drone dynamically observes and analyzes the surrounding traffic and pedestrians, and selects a safe area to land when the opportunity arises; 3) After the drone lands, the second pivot controls the upper part of the cabin door to fully open upwards and the lower part to open downwards until it touches the ground. 4) Turn on camera number one and warning light number one. After the positioning slot opens, release the wheels. The warning device deployment vehicle slowly drives out of the transport container under the drive of the wheels and moves along the lower part of the door to the road surface. 5) The warning device deployment vehicle advances along the preset work path. After reaching the first cone placement position, the No. 1 telescopic rod and the No. 2 telescopic rod extend to move the gantry out of the equipment box until it is fully opened. 6) The warning device deployment vehicle deploys cones in a forward sequence. The slider moves along the second telescopic rod to the first cone outside the equipment box. The grab handle opens and closes to grab the cone, and the lock releases its fixation on the cone. The slider lifts the cone by retracting and moves along the second telescopic rod to above the placement position of the first cone. The slider places the cone on the road by extending. The grab handle opens and releases the cone. The slider then retracts again to move away from the cone. 7) The deployment vehicle moves to the location of the second cone and repeats step 6) until all cones are in place. The warning device deployment vehicle then stops in a safe area. 8) After the accident vehicle handling or rescue work is completed, the warning device deployment vehicle will retrieve the cones in reverse order; 9) The warning device deployment vehicle first moves to the last cone placement position. The grabber grasps the cone by opening and closing, the slider retracts and lifts the cone, and moves along the second telescopic rod to the innermost lock of the equipment box. The slider extends and places the cone into the lock, the lock fixes the cone, the grabber opens and releases the cone, and the slider retracts and moves to the next cone. Repeat step 9) until all cones are retrieved. 10) The No. 1 and No. 2 telescopic poles retract to move the gantry into the equipment box until it is closed. The warning device deployment vehicle drives towards the transport box, climbs up the slope of the lower part of the door and moves into the transport box. The positioning slot tightens and fixes the wheels. The No. 2 rotating shaft controls the upper and lower parts of the door to close respectively through its rotation. The drone observes the surrounding environment through the camera and flies back safely when the opportunity arises. The operation is completed.

[0015] The present invention has the following beneficial effects: In practical operation, the air-ground collaborative road traffic accident warning device deployment system and method described in this invention connects the interactive decision-making system with the warning device deployment vehicle and the unmanned transport container.
