Description

Technical Field

[0001] This application relates to the technical field of autonomous obstacle avoidance training grounds for unmanned aerial vehicles (UAVs), and specifically discloses an adjustable autonomous obstacle avoidance training device for UAVs. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices. Before leaving the factory, UAVs need to undergo performance testing. Currently, UAV performance testing generally involves obstacle avoidance tests by building obstacles that simulate real-world environments. However, this testing method requires a large area of ​​space and involves significant investment; the obstacles are poorly adjustable after construction, and the simulated obstacle attributes are limited.

[0003] Chinese Patent Publication No. CN220430522U discloses a training maze for testing the obstacle avoidance function of drones. The maze includes a maze body with an entrance and an exit. Multiple testing devices are installed within the maze body, including a crossbar, a track trolley, a rope, and a foam board. A track for the track trolley to move is set inside the crossbar, and the rope connects the track trolley to the foam board. This invention uses a track trolley that moves back and forth along the track along the length of the crossbar. The track trolley, driven by the rope, moves the foam board back and forth. Compared to balloons, the foam board can be placed for a longer period and is less likely to be damaged by the drone, thus solving the problem of frequently replacing balloons due to reasons such as balloon leakage and drone collisions.

[0004] The above solution still has some problems:

[0005] Obstacle avoidance training grounds have fixed routes. For autonomous drones undergoing long-term training, the algorithms, paths, flight paths, and task procedures are all fixed. Moreover, after deep learning, such fixed obstacle avoidance training grounds are meaningless. They also do not match the actual flight environment, which should take into account the sudden collisions with birds and other animals. Traditional obstacle avoidance training grounds lack the ability for drones to respond to unexpected situations, thus hindering deep learning and preventing algorithm optimization. In view of this, this utility model provides an adjustable autonomous obstacle avoidance training device for drones to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that traditional drone autonomous obstacle avoidance training, which is conducted in fixed locations, does not have the significance of long-term training.

[0007] To achieve the above objectives, this utility model provides the following basic solution:

[0008] An adjustable unmanned aerial vehicle (UAV) autonomous obstacle avoidance training device includes a warehouse, openings at both ends of the warehouse serving as the starting and ending points for UAV obstacle avoidance training, uniformly arranged fixed plates inside the warehouse, movable plates positioned between adjacent fixed plates, and a mobile gantry crane for moving the movable plates. The mobile gantry crane is located on the top of the warehouse and connected to the movable plates via suspension ropes.

[0009] After the movable board moves, it forms a training area with the fixed board, and the training area includes a first straight track, a second straight track, and a curve.

[0010] The first straight section and the second straight section are equipped with a first ejection assembly and a second ejection assembly for UAV on-site capability training, and the curve is equipped with a multi-path training assembly.

[0011] Furthermore, the warehouse has a roller shutter door at its opening. When the warehouse is needed, the roller shutter door is normally open; when the warehouse is not needed, the roller shutter door is normally closed. Near the top of the warehouse, there is an observation room and a climbing frame for people to enter the observation room. The climbing frame is located at the bottom inside the warehouse.

[0012] Furthermore, the fixed plates are arranged vertically and evenly along the starting and ending directions.

[0013] Furthermore, the curve represents the initial layout of the training area, where the moving plates are staggered at the ends of the fixed plates, forming a multi-path training area between adjacent moving plates and fixed plates, and the multi-path training component is installed within the multi-path training area.

[0014] Furthermore, the multi-path training component includes several cylinders pre-embedded in the bottom of the warehouse and stop levers set at the protruding ends of the cylinders. When the multi-path training component is not in use, the stop levers are flush with the end face of the bottom of the warehouse. It also includes a controller for controlling the raising of different stop levers. The raising of different stop levers forms multi-path training. A path endpoint indicator is set on the moving plate in the multi-path training area.

[0015] Furthermore, after the movable plate moves upward and remains flush with the end of the fixed plate, it forms the first straight track; after the movable plate moves downward and remains flush with the end of the fixed plate, it forms the second straight track.

[0016] Furthermore, the first catapult assembly includes a first catapult and a first flying disc used in conjunction with the first catapult.

[0017] Furthermore, the second catapult assembly includes a second catapult and a second flying disc used in conjunction with the second catapult.

[0018] Furthermore, the launching direction of the first flying disc includes from the top of the warehouse to the bottom of the warehouse and from the bottom of the warehouse to the top of the warehouse, while the launching direction of the second flying disc is horizontal launching.

[0019] The principle and effect of this solution are as follows:

[0020] 1. Compared with the prior art, this utility model is based on a large warehouse as the core design, uses a fixed plate as a moving channel, and uses a moving plate and a moving gantry crane arranged on the top of the large warehouse. The moving gantry crane drives the moving plate to move, thereby changing the relative positional relationship between the moving plate and the fixed plate, and thus changing the layout of the obstacle avoidance training site. After human control, it can be ensured that the obstacle avoidance training path of each UAV training is inconsistent, thereby solving the problem that the traditional UAV autonomous obstacle avoidance training is not meaningful for long-term training because it is based in a fixed site.

[0021] 2. Compared with the prior art, this utility model has straight-line training function and curve training function, and on the basis of the straight-line training function, it is provided with a first ejection component and a second ejection component, and the adaptability of the UAV is trained based on the first ejection component and the second ejection component.

[0024] Figure 2 The diagram shows a top view of the first ejection assembly and the second ejection assembly in an adjustable UAV autonomous obstacle avoidance training device according to an embodiment of this application. Detailed Implementation

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The reference numerals in the accompanying drawings include: warehouse 1, fixed plate 2, movable plate 3, path end indicator 4, stop bar 5, roller shutter door 6, second straight track 7, second ejection assembly 8, first straight track 9, first ejection assembly 10, and mobile gantry crane 11.

[0027] Implementation, for example Figure 1 and Figure 2 As shown:

[0028] An adjustable unmanned aerial vehicle (UAV) autonomous obstacle avoidance training device includes a warehouse 1, with openings at both ends serving as the starting and ending points for UAV obstacle avoidance training, uniformly arranged fixed plates 2 inside the warehouse 1, movable plates 3 positioned between adjacent fixed plates 2, and a mobile gantry crane 11 for moving the movable plates 3. The mobile gantry crane 11 is located on the top of the warehouse 1 and connected to the movable plates 3 via suspension ropes.

[0029] About Warehouse 1:

[0030] A roller shutter door 6 is provided at the opening of warehouse 1. When warehouse 1 is needed, the roller shutter door 6 is normally open; when warehouse 1 is not needed, the roller shutter door 6 is normally closed. Near the top of warehouse 1, there is an observation room and a climbing frame for people to enter the observation room. The climbing frame is located at the inner bottom of warehouse 1.

[0031] The observation room is used by technicians to observe the drone's autonomous obstacle avoidance training from above. Warehouse 1, fixed plate 2, and movable plate 3 form an obstacle avoidance training area.

[0032] After the movable plate 3 moves, it forms a training area with the fixed plate 2. The training area includes a first straight track 9, a second straight track 7, and a curve.

[0033] The curve is the initial layout of the training area. At this time, the moving plates 3 are staggered at the ends of the fixed plates 2, and a multi-path training area is formed between adjacent moving plates 3 and fixed plates 2. The multi-path training components are installed in the multi-path training area.

[0034] like Figure 1 As shown:

[0035] The fixed plates 2 are arranged vertically and evenly along the direction of the starting point and the ending point.

[0036] The first straight section 9 and the second straight section 7 are equipped with a first ejection assembly 10 and a second ejection assembly 8 for UAV on-site capability training, and the curves are equipped with multi-path training components.

[0037] Furthermore, a roller shutter door 6 is provided at the opening of the warehouse 1. When the warehouse 1 needs to be used, the roller shutter door 6 is normally open; when the warehouse 1 is not needed, the roller shutter door 6 is normally closed. Near the top of the warehouse 1, there is an observation room and a climbing frame for people to enter the observation room. The climbing frame is located at the bottom inside the warehouse 1.

[0038] The multi-path training component includes several cylinders pre-embedded in the bottom of the warehouse 1 and a stop bar 5 set at the extended end of the cylinder. When the multi-path training component is not in use, the stop bar 5 is flush with the end face of the bottom of the warehouse 1. It also includes a controller for controlling the raising of different stop bars 5. The raising of different stop bars 5 forms multi-path training. A path endpoint indicator 4 is set on the movable plate 3 in the multi-path training area.

[0039] Specifically:

[0040] The controller is used to raise different levers 5 to form a multi-path training, and then the drone is forced to bypass the levers 5 to find the path end indicator 4. This path end indicator 4 is not the end indicator, but the intermediate path end indicator 4. It is equivalent to the drone having the same start and end point, but multiple path end indicators 4 are added on the route between the start and end point. The drone must find each path end indicator 4 to find the end point.

[0041] like Figure 1 As shown, there are multiple path end indicators 4 on the curve, and there are multiple situations where the levers 5 are raised. With different combinations, there are a great many route training routes.

[0042] This enables drones to learn through deep learning for autonomous obstacle avoidance;

[0043] After the movable plate 3 moves upward and remains flush with the end of the fixed plate 2, it forms the first straight track 9. After the movable plate 3 moves downward and remains flush with the end of the fixed plate 2, it forms the second straight track 7.

[0044] Regarding the first ejection assembly 10 and the second ejection assembly 8:

[0045] The first launch assembly 10 includes a first launcher and a first flying disc used in conjunction with the first launcher. The second launch assembly 8 includes a second launcher and a second flying disc used in conjunction with the second launcher. The launch direction of the first flying disc includes from the top of the warehouse 1 to the bottom of the warehouse 1 and from the bottom of the warehouse 1 to the top of the warehouse 1. The launch direction of the second flying disc is horizontal launch.

[0046] Both the first and second catapults are catapults for frisbee shooting. These catapults can launch frisbees. In this case, different launch trajectories were designed to simulate accidental collisions in actual situations, thereby achieving deep learning for on-site emergency response of drones.

[0047] This device solves the problem that traditional UAV autonomous obstacle avoidance training is limited to fixed locations and lacks long-term training significance.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
