Description

Technical Field

[0001] This invention relates to the field of airborne object capture technology, specifically to a low-altitude airborne object capture device and method. Background Technology

[0002] In recent years, incidents involving airborne objects (AVs) at airports have been frequent. Balloons accidentally released by people, or ground debris and soft objects blown up by strong winds, can all pose a threat to aviation safety. Traditional AV monitoring relies on manual inspections and radar detection, which suffers from low efficiency, high false negative rates, and limited response methods (physical interception alone). While drones have been explored for airspace security in recent years, their image recognition algorithms lack accuracy in complex weather conditions and lack efficient coordination with response devices. Existing capture and interception methods have certain shortcomings and technical difficulties. For example, high-altitude targets struggle to handle AVs (balloons) exceeding 500 meters in altitude, and traditional interception equipment has insufficient range; radar has weak detection capabilities for non-metallic objects (such as polyethylene balloons), and optical recognition is susceptible to environmental interference. In terms of cost and efficiency, there are issues of low economic viability and slow response times. Laser or drone interception systems are expensive per use and unsuitable for frequent deployment, with long lead times from detection to interception, by which time the target may have already drifted out of the controlled area. In terms of safety risks, there is a risk of secondary harm and accidental injury. Shooting or netting may cause airborne objects to fall and injure people, especially in densely populated areas. Electromagnetic interference may affect nearby legal electronic equipment.

[0003] Therefore, it is necessary to develop and design devices and methods for capturing low-altitude airborne objects. Fast response speed, high capture accuracy, and no need for manual capture are technical problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a low-altitude airborne object capture device and method, which features fast response speed, high capture accuracy, and eliminates the need for manual capture.

[0005] To achieve the above objectives, the present invention provides the following solution: A low-altitude airborne object capture device, characterized in that it includes an unmanned aerial vehicle (UAV) platform, an image recognition module disposed on the UAV platform, a thrower disposed at the bottom of the UAV platform, a power module disposed on the thrower, a capture net disposed on the thrower, and a positioning device for positioning the capture net, wherein the image recognition module is used to locate the airborne object.

[0006] Preferably, the positioning device includes four positioning modules set on the ground and a signal receiver set on the net. The four positioning modules are placed at four different locations to form four base stations. The net is located within the area formed by the four base stations and is connected to the signals of the four base stations through the signal receiver. The distance from the net to the four base stations is calculated to determine the position of the net.

[0007] Preferably, the thrower is provided with a locking mechanism, which is connected to the suspension line of the net.

[0008] Preferably, the locking mechanism includes a locking body, an internal cavity for accommodating the net, a telescopic plate at the bottom of the locking body for the net to fall out of the cavity, and the inner wall of the cavity is connected to the suspension line.

[0009] Preferably, it also includes a control system, which is electrically connected to the positioning device, the image recognition module, and the drive mechanism of the telescopic plate.

[0010] Preferably, the thrower is positioned in the middle of the drone platform via a connecting bandage.

[0011] Preferably, the net is woven from nylon rope.

[0012] This invention also discloses a method for capturing low-altitude airborne objects, using the low-altitude airborne object capturing device described above, with the main steps as follows: The image recognition module analyzes camera data on the drone platform to identify the location of airborne objects. The drone automatically adjusted its flight path to be above the airborne object; Release the fishing net's hanging line; The net unfolds under the influence of gravity, covering the surface of the airborne object and completing the capture.

[0013] Preferably, the drone platform flies directly above the airborne object and maintains a safe hovering height of 5 to 10 meters.

[0014] Preferably, after the net covers the airborne object, the net's position is tracked by a positioning device, and the net is retrieved for reuse.

[0015] The present invention achieves the following technical effects compared to the prior art: The image recognition module can detect the specific location of airborne objects, thereby driving the drone platform to move towards the object. When the drone platform, equipped with a capture net, is directly above the airborne object, it lowers the net to capture it. Finally, the positioning device locates the position of the capture net for retrieval, which can greatly improve capture efficiency, eliminate the need for manual inspection, increase response speed, and ensure the accuracy of both object capture and net retrieval by setting up the image recognition module and positioning device.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The purpose of this invention is to provide a device and method for capturing low-altitude airborne objects, which has a fast response speed, high capture accuracy, and does not require manual capture.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] refer to Figures 1-3The low-altitude airborne object capture device disclosed in this embodiment of the invention includes at least a drone platform 1. The drone platform 1 is equipped with an image recognition module for locating airborne objects 5. A thrower 2 is located at the bottom of the drone platform 1, and a power supply for the thrower 2 is provided on the thrower 2. A net 4 is mounted on the thrower 2, and a positioning device for locating the net 4 is also included. The image recognition module can detect the specific position of the airborne object 5, thereby driving the drone platform 1 to move towards the airborne object 5. When the drone platform 1, carrying the net 4, is directly above the airborne object 5, the net 4 is lowered to capture the airborne object 5. Finally, the positioning device locates the position of the net 4 for recycling. This greatly improves the capture efficiency, eliminates the need for manual inspection for capture, increases the response speed, and ensures the accuracy of capturing the airborne object 5 and the accuracy of retrieving the net 4 by setting up the image recognition module and the positioning device.

[0022] It should be noted that the image recognition module integrates an enhanced deep learning algorithm for real-time analysis of the type, location, and trajectory of airborne objects. The drone platform 1 is equipped with a high-definition camera (D435) and a GPS positioning module, serving as a mobile carrier and data acquisition terminal. The image recognition module is coaxially mounted with the drone camera to ensure that the recognition data and visual information are synchronized.

[0023] refer to Figure 3 In one embodiment, the positioning device includes four positioning modules 6 set on the ground and a signal receiver set on the net 4. The four positioning modules 6 are placed at four different locations to form four base stations. The net 4 is located within the area formed by the four base stations. The net 4 is connected to the four base stations through the receiver of the net 4. The distance from the net 4 to the four base stations is calculated to determine the position of the net 4. The x, y, z axis coordinates and real-time movement trajectory of the net 4 can be read on the host computer software.

[0024] It should be noted that positioning module 6 is a UWB positioning and ranging module.

[0025] refer to Figure 1 As one implementation method, the thrower 2 is equipped with a locking mechanism, which is connected to the suspension line 3 of the net 4. By setting the locking mechanism, the net 4 can be automatically lowered, thus improving the response speed.

[0026] refer to Figure 1As a preferred embodiment, the locking mechanism includes a locking body, the inside of which is provided with a receiving cavity for accommodating the net 4. The bottom of the locking body is provided with a telescopic plate for the net 4 to fall out of the receiving cavity. The locking body is also provided with a drive mechanism for driving the telescopic plate to extend and retract. The inner wall of the receiving cavity is connected to the suspension line 3. When it is necessary to lower the net 4, the telescopic plate is driven by the drive mechanism to make the receiving cavity form an opening for the net 4 to fall. The net 4 falls without the telescopic plate blocking it, and spreads out under the action of gravity, covering the airborne object 5, thereby capturing the airborne object 5.

[0027] refer to Figure 1 As a preferred method, the thrower 2 is set in the middle of the drone platform 1 by connecting bandages. By setting connecting bandages, it is easy to assemble and disassemble the thrower 2 from the drone platform 1, and setting the thrower 2 in the middle of the drone platform 1 can ensure the stability of the drone platform 1 during flight.

[0028] refer to Figure 1 As a method of implementation, the fishing net 4 is woven from high-strength nylon rope.

[0029] It should be noted that the main load-bearing net body in the trap 4 adopts a woven structure of ultra-high molecular weight polyethylene (UHMWPE) fiber, with a specific strength of over 35 cN / dtex, which improves the breaking strength by 300% compared to traditional nylon rope, while achieving a 40% weight reduction (density 0.97 g / cm³ vs nylon 1.14 g / cm³). Through molecular orientation control technology, while maintaining a flexibility of 18% elongation at break, its creep resistance is 5 times better than nylon, making it more suitable for dynamic load conditions. The edge load-bearing system adopts para-aramid (Kevlar® K49) composite rope. Through the sheath core structure design and the surface silane coupling agent treatment, the cut resistance level reaches the ANSI / ISEA 105-2016 Level 5 standard, while maintaining the stability of the working temperature. The dual-material system achieves modulus gradient matching through a 3D woven transition layer, avoiding interface delamination failure caused by stress concentration.

[0030] refer to Figure 1 As one implementation method, it also includes a control system. The control system is electrically connected to the positioning device, the image recognition module, and the drive mechanism of the telescopic plate. By setting the control system, the data collected by the image recognition module can be analyzed and calculated. After determining the specific location of the airborne object 5, the control system controls the drive mechanism to drive the telescopic plate to move, and then lowers the net 4 to complete the capture of the airborne object 5. After the capture is completed, the control system analyzes the data collected by the positioning device to locate the position of the net 4 so as to retrieve the net 4.

[0031] It should be noted that a remote control for controlling the opening and closing of the drive device is also included. The remote control is connected to the control system signal. By setting the remote control, it is convenient for operators to operate and lower the net 4.

[0032] This invention also discloses a method for capturing low-altitude airborne objects 5, which uses the low-altitude airborne object 5 capturing device described above, and the main steps are as follows: The image recognition module analyzes the camera data on the drone platform 1, identifies the airborne object 5 and calculates its three-dimensional coordinates, and sends the coordinate signal of the airborne object 5 to the control system. The drone platform 1 combines GPS positioning and meteorological data to plan the optimal interception path and automatically adjusts its flight path to above the airborne object 5. The drone platform 1 flies directly above the airborne object 5 and maintains a safe hovering height of 5 to 10 meters; The operator sends an unlock signal via remote control, which drives the telescopic plate to release the suspension line 3 of the net 4; The net 4 unfolds under the influence of gravity, covering the surface of the airborne object 5; The location of the net is monitored and tracked in real time by a positioning device, and the net 4 is retrieved for reset and standby.

[0033] It should be noted that, for those skilled in the art, it is obvious that the present 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 characteristics 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. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
