Description

Technical Field

[0001] This invention relates to the field of drone countermeasures and capture technology, and in particular to a net-capture drone system. Background Technology

[0002] With the rapid development of drone technology, the phenomenon of "unauthorized drone flights" has become increasingly prominent, posing a serious threat to public safety, aviation safety, and national security. Related technologies typically employ non-physical interception techniques and physical interception techniques to intercept target drones.

[0003] Non-physical interception technologies mainly counter "black flight" drones through electromagnetic interference, laser damage, or firepower, but they have obvious drawbacks: the range of electromagnetic interference is difficult to control precisely, which can easily affect legitimate electronic devices in the vicinity, and its effectiveness decreases as drone anti-interference technology develops; laser damage is significantly affected by the environment, poses safety hazards, and is costly; firepower has limited applicability, is difficult to use in densely populated areas, and may cause collateral damage.

[0004] Physical interception technologies include impact interception, biological interception, and net capture interception. While net capture technology has the advantage of low damage, the accuracy of drones using net capture projectiles is greatly affected by airflow, with an effective range of only within 50 meters, a small coverage area, and the projectiles being disposable. For drones using net capture, the net takes 3-5 seconds to deploy, with an optimal capture window of only 1-2 seconds. During this time, the drone may fly out of range, resulting in a success rate of less than 30%. Furthermore, the net capture method has limited repeatability; once used, it requires returning to replenish the net, leading to high net replacement costs, time-consuming operation by specialized personnel, and an inability to achieve continuous operation. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, embodiments of the present invention propose a net-capturing drone system to achieve efficient capture and continuous operation of target drones.

[0007] The net-catching drone system of this invention includes: The drone body has an interception hole at its center and a fixing part around the interception hole; A net storage device is installed on the UAV body, and the net storage device stores multiple nets. The outer edge of the nets is provided with an assembly part. A net-laying drive device is located on the UAV body. The net-laying drive device is used to deliver the net to unfold at the interception hole. The assembly part and the fixing part cooperate to lock. After the net contacts the target UAV, the assembly part and the fixing part unlock, and the net retracts to capture the target UAV.

[0008] In some embodiments, the storage net device adopts a roll-type structure, with multiple fishing nets sequentially wound around the storage net device, and adjacent fishing nets being detachably connected.

[0009] In some embodiments, a connector is provided between two adjacent nets, the connector having a slit band so that the two adjacent nets can be disconnected.

[0010] In some embodiments, the fixing part includes a plurality of electromagnets arranged at intervals around the intercepting hole, and the mounting part includes magnetic blocks corresponding one-to-one with the plurality of electromagnets.

[0011] In some embodiments, a pressure sensor is provided between the electromagnet and the magnetic block. The pressure sensor is used to monitor the pressure between the electromagnet and the magnetic block, and to control the electromagnet to be energized or de-energized according to the pressure between the electromagnet and the magnetic block.

[0012] In some embodiments, the net-setting drive device includes a slide rail, a drive member, and a clamping member. The drive member is disposed on the slide rail and connected to the clamping member. The drive member is used to drive the clamping member to clamp or release the net.

[0013] In some embodiments, the net-catching drone system has a first mode and a second mode. In the first mode, the net is deployed at the interception hole, and the clamping member clamps another net adjacent to the net at the interception hole. In the second mode, the clamping member clamps the outermost net on the net storage device, and the net is delivered deployed at the interception hole.

[0014] In some embodiments, the UAV body integrates an optoelectronic payload, which is used to detect the position and motion parameters of the target UAV in real time.

[0015] In some embodiments, the photoelectric payload is electrically connected to the control module of the UAV body, so that the control module plans the pursuit path according to the target motion parameters and adjusts the attitude of the UAV body so that the net at the interception hole is aligned with the target flight trajectory.

[0016] The net-catching drone system of this invention adopts a normally unfolded mesh-like hollow structure net, which has a "swallowing" design similar to the mouth of a fish, enabling it to maintain high-speed pursuit capability and extend its flight time.

[0017] The net's automatically deployable design eliminates the need for temporary deployment, significantly extending the effective capture window. When the target drone's rotor contacts the net, the high-strength, lightweight fiber material woven into the mesh structure quickly wraps around the propeller, forcing it to stop working and improving the capture success rate. Furthermore, the locking mechanism between the assembly and fixing parts ensures the net's stability during flight.

[0018] The system is equipped with a net storage device to store multiple spare nets. After a capture is completed, the net setting and reloading operation is automatically performed by the net setting drive device to restore the system to the capture state. This allows the UAV to perform multiple capture missions continuously without returning to base, greatly improving operational efficiency.

[0019] When the target drone collides with the net, its kinetic energy triggers the unlocking of the assembly and fixing parts. The net then automatically retracts to capture the target drone due to its inertia and is discharged from the back of the drone. This automated capture-release mechanism eliminates the need for complex manual intervention or return-to-base procedures, simplifying the operation. Through the automated net replacement mechanism and continuous operation capability, the system reduces the need for manual maintenance and the number of return trips, lowering both the cost per capture and long-term operating costs.

Detailed Implementation

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The net-catching drone system of the present invention is described below with reference to the accompanying drawings.

[0027] like Figures 1 to 4 As shown, the net-catching drone system of this embodiment includes a drone body 1, a net storage device 2, and a net-setting drive device 3.

[0028] An interception hole is provided at the center of the drone body 1, and a fixing part 11 is provided around the interception hole. A net storage device 2 is provided on the drone body 1, and the net storage device 2 stores multiple nets 21. An assembly part 22 is provided on the outer edge of the net 21. A net-setting drive device 3 is provided on the drone body 1. The net-setting drive device 3 is used to transport the nets 21 to unfold at the interception hole. The assembly part 22 and the fixing part 11 cooperate to lock. After the nets 21 come into contact with the target drone 10, the assembly part 22 and the fixing part 11 unlock, and the nets 21 retract and capture the target drone 10.

[0029] Understandably, a normally deployed net 21 is located at the very center of the front of the drone body 1. Its structural layout is similar to the shape of a fish's mouth, enabling it to "swallow" the target drone 10 during pursuit. The edge of the net 21 is connected to the drone body 1 through the cooperation of the mounting part 22 and the fixing part 11. This structure has two stable states: in the normal state, it remains locked, with the net 21 deployed and in a position to be captured; when subjected to specific kinetic energy (when the target drone 10 collides with the net 21), a state switch can be triggered, unlocking the mounting part 22 and the fixing part 11, and the net 21 retracts to capture the target drone 10 and is discharged from the back of the drone body 1.

[0030] The storage device 2 can store spare nets 21, and after a capture operation is completed, the net-setting drive device 3 automatically performs the reset and reloading operation of nets 21, so that the system returns to the ready-to-capture state and waits to perform the next capture operation.

[0031] The capture net 21 is woven from high-strength, lightweight fiber materials. Its mesh-like hollow structure design minimizes flight drag, ensuring the drone has high-speed pursuit capabilities. When the rotor of the target drone 10 comes into contact with the capture net 21, it quickly wraps around the propeller of the target drone 10, forcing its rotor to stop working immediately.

[0032] The net-catching drone system of this invention adopts a normally unfolded mesh-like hollow structure net 21, which has a "swallowing" design similar to the mouth of a fish, enabling it to maintain high-speed pursuit capability and extend its flight time.

[0033] The capture net 21 features a normally deployable design that eliminates the need for temporary deployment, significantly extending the effective capture window. When the rotor of the target UAV 10 contacts the capture net 21, the mesh structure woven from high-strength, lightweight fiber material quickly wraps around the propeller, forcing it to stop working and improving the capture success rate. Furthermore, the locking mechanism between the assembly part 22 and the fixing part 11 ensures the stability of the capture net 21 during flight.

[0034] The system is equipped with a net storage device 2 to store multiple spare nets 21. After a capture is completed, the net setting drive device 3 automatically performs the net reset and reloading operation to restore the system to the capture state. This allows the UAV body 1 to perform multiple capture tasks continuously without returning to base, greatly improving operational efficiency.

[0035] When the target drone 10 collides with the capture net 21, its kinetic energy triggers the assembly part 22 to unlock from the fixing part 11. The capture net 21 automatically retracts to capture the target drone 10 due to its inertia and is discharged from the back of the drone body 1. This automated capture-release mechanism eliminates the need for complex manual intervention or return-to-base procedures, simplifying the operation process. Through the automated net 21 replacement mechanism and continuous operation capability, the system reduces the need for manual maintenance and the number of return trips, lowering both the cost of a single capture and the long-term operating cost.

[0036] In some embodiments, such as Figure 2 As shown, the storage net device 2 adopts a roller structure, with multiple nets 21 wound sequentially around the storage net device 2.

[0037] The roll-type net storage device 2 forms a compact roll by spirally winding multiple nets 21 onto a central axis, storing the flexible nets 21 in a minimal volume, maximizing the use of limited space, accommodating more spare nets 21 within a limited space, and significantly improving the continuous operation capability of the UAV.

[0038] The release speed and direction of the net 21 are controlled by rotating the axis, preventing tangling or jamming. The reel structure keeps the net 21 flat, preventing damage from wrinkles during storage. The reel structure is relatively simple, has a low failure rate, and low maintenance costs.

[0039] Furthermore, adjacent nets 21 are detachably connected. Understandably, after a net 21 captures the target drone 10, it needs to be released and retracted from the drone body 1. If adjacent nets 21 are firmly connected, all nets 21 on the reel might be pulled out together, affecting subsequent capture operations. The detachable connection ensures that only the currently used net 21 is released after capture, while other spare nets 21 remain intact for subsequent use.

[0040] Optionally, two adjacent nets 21 can be connected by Velcro or by a snap fastener with protrusions and grooves.

[0041] Preferably, such as Figure 4 As shown, a connector 23 is provided between two adjacent nets 21. The connector 23 is a strip of material with a certain width, made of a material with high strength but moderate toughness. The connector 23 has a slit band 231, which can be straight, wavy, or serrated, etc., so that the connection between the two adjacent nets 21 can be broken. That is, a series of tiny weak points are preset on the connector 23 to guide the tearing along a predetermined path.

[0042] When the net 21 is impacted by the target drone 10 and begins to retract, the connector 23 is subjected to tensile force. The material at the crack zone 231 first reaches its fracture strength, causing the connector 23 to tear along the crack zone 231, thus separating adjacent nets 21. The design of the crack zone 231 ensures that the tearing occurs along a predetermined path, avoiding uncontrollable tearing direction that could damage the net 21.

[0043] In some embodiments, such as Figures 1 to 3 As shown, the fixing part 11 includes a plurality of electromagnets 111 arranged at intervals around the interception hole, and the assembly part 22 includes magnetic blocks 221 corresponding to the plurality of electromagnets 111 one by one, forming a multi-point magnetic connection system. The electromagnets 111 generate a magnetic field by being energized, attracting the corresponding magnetic blocks 221, thereby achieving a firm fixation between the net 21 and the UAV body 1.

[0044] Electromagnet 111 controls the magnetic field strength by means of current. When energized, it generates a magnetic force to attract magnetic block 221. When the power is turned off, the magnetic field disappears and the magnetic force disappears as well. This allows the system to precisely control the fixing and release of net 21 without the need for a complex mechanical structure.

[0045] Multiple electromagnets 111 are arranged at intervals to form a ring magnetic field region. With the corresponding magnetic blocks 221, a uniform force distribution is achieved at multiple points, avoiding connection instability caused by excessive force at a single point. At the same time, redundancy is provided so that even if some magnetic points fail, other magnetic points can still keep the net 21 fixed.

[0046] Furthermore, a pressure sensor (not shown in the figure) is provided between the electromagnet 111 and the magnetic block 221. The pressure sensor is used to monitor the pressure between the electromagnet 111 and the magnetic block 221, and to control the electromagnet 111 to be energized or de-energized according to the pressure between the electromagnet 111 and the magnetic block 221.

[0047] A pressure sensor monitors the contact pressure between electromagnet 111 and magnetic block 221 in real time, establishing a correspondence between the pressure state and the state of net 21. During normal flight, electromagnet 111 is energized, generating a magnetic force that attracts magnetic block 221. The pressure sensor detects a stable pressure value, indicating that net 21 is in a fixed state. When the target drone 10 collides with net 21, its kinetic energy is transferred through net 21 to magnetic block 221, causing a slight displacement of magnetic block 221 away from electromagnet 111, resulting in a sudden change in contact pressure. This pressure change is precisely captured by the sensor and serves as a trigger signal for target capture.

[0048] The pressure sensor accurately detects pressure changes caused by the impact of the target drone 10, ensuring immediate release after capture to prevent the drone 10 from escaping. The system only triggers release upon detecting a sudden pressure change, avoiding misoperation due to non-target factors such as airflow vibration. The entire capture and release process is fully automated, requiring no real-time monitoring or judgment by operators. It is triggered directly by physical signals, reducing signal transmission and processing delays and improving response speed.

[0049] In some embodiments, such as Figure 2 As shown, the net-holding drive device 3 includes a slide rail 31, a drive member 32, and a clamping member 33. The drive member 32 is mounted on the slide rail 31 and is connected to the clamping member 33. The drive member 32 is used to drive the clamping member 33 to clamp or release the net 21.

[0050] The slide rail 31 serves as a motion guide, providing a precise linear motion path to ensure that the drive component 32 moves along a predetermined trajectory. The drive component 32 can be a linear motor or a servo motor, converting rotational motion into linear motion and providing precise and controllable driving force. The clamping component 33 is an openable and closable mechanical structure (such as a gripper, latch, or vacuum suction cup) to grasp and release the net 21.

[0051] The net-catching drone system of this invention has a first mode and a second mode.

[0052] In the first mode, the system has an extended net 21 at the interception hole, and the clamping member 33 clamps another net 21 adjacent to the net 21 at the interception hole.

[0053] That is, in this mode, the system is in the pursuit and capture phase, and the UAV body 1 carries the deployed capture net 21 to pursue the target UAV 10. The deployed capture net 21 (the currently used capture net 21) is kept at the interception hole, and the clamping member 33 pre-clamps another capture net 21 adjacent to the current capture net 21 (the spare capture net 21). The system is in pursuit state, and the UAV body 1 carrying the deployed capture net 21 approaches the target UAV 10 at high speed.

[0054] When the target drone 10 collides with the current net 21, the pressure sensor detects a sudden pressure change. The control module immediately outputs a power-off signal, de-energizing the electromagnet 111, and the current net 21 detaches from the drone body 1. Since the clamping member 33 has pre-clamped the adjacent net 21, the current net 21 can easily disconnect from the backup net 21 when the target drone 10 collides with it. Furthermore, it facilitates the timely reset and reinstallation of the backup net 21.

[0055] In the second mode, the clamping element grips the outermost net 21 of the reel, and the net 21 is conveyed and unfolded at the interception hole. In this mode, the system has completed one capture operation and is in the net 21 reset and reloading stage.

[0056] The drive unit 32 is activated, causing the clamping member 33 to move along the slide rail 31. The clamping member 33 pulls the net 21 off the reel and conveys it to the interception hole. The net 21 unfolds at the interception hole, and the assembly part 22 and the fixing part 11 cooperate to lock it, completing the reset and reinstallation of the net 21. The clamping member 33 releases and returns to its initial position, clamping the spare net 21 as in the first mode, ready for the next operation.

[0057] The net-catching drone system of this invention forms a closed-loop workflow in two modes, with state transitions automatically triggered by the control system to ensure process continuity.

[0058] In some embodiments, such as Figure 1 As shown, the UAV body 1 integrates an optoelectronic payload 4. The optoelectronic payload 4 adopts multi-sensor fusion technology and is used to detect and identify the position, flight trajectory and motion parameters of the target UAV 10 in real time.

[0059] The optoelectronic payload 4 includes a high-definition camera, an infrared detector, a laser rangefinder, and a target tracking module. The high-definition camera captures visible light images, providing visual characteristics, position, and attitude information of the target UAV 10. The infrared detector detects the difference in thermal radiation between the target UAV 10 and the background, enabling all-weather target identification. The laser rangefinder emits a laser beam and receives reflected signals, accurately measuring the distance to the target. The target tracking module integrates image processing algorithms to achieve real-time target tracking and identification.

[0060] Furthermore, the photoelectric payload 4 is electrically connected to the control module of the UAV body 1, so that the control module plans the pursuit path according to the target motion parameters and adjusts the attitude of the UAV body 1 so that the net 21 at the interception hole is aligned with the target flight trajectory.

[0061] The control module adopts a hierarchical control architecture. The perception layer receives the target parameters of the photoelectric payload 4, the decision layer calculates the optimal path based on the target parameters and UAV constraints, and the execution layer transforms the path planning into specific control commands.

[0062] By integrating advanced optoelectronic payloads and an intelligent path planning system, efficient and precise interception of net-capture drones was achieved. Multi-sensor fusion ensured high-precision target detection in all weather conditions, while the intelligent path planning algorithm enabled predictive interception and optimal attitude adjustment, significantly improving the capture success rate and system adaptability.

[0063] In summary, the working process of the net-catching drone system according to the embodiments of the present invention is described below.

[0064] Detection and pursuit phase: After the system is started, the photoelectric payload 4 continuously scans the airspace. When the target UAV 10 is identified, the control module plans the pursuit path according to the target motion parameters and drives the UAV body 1 to approach the target at high speed. At this time, the capture net 21 remains in a normal deployed state.

[0065] Acquisition Phase: When the UAV reaches the target's acquisition range, the UAV adjusts its attitude using real-time positioning via the optoelectronic payload 4, aligning the capture net 21 with the target's flight path. The UAV 10 is then captured by the net 21 through a swallowing motion. Once the target's rotor contacts the net 21, its power system ceases operation.

[0066] Release phase: Due to inertia, the target drone 10 continues to move, and its kinetic energy acts on the assembly part 22 of the capture net 21, causing it to unlock from the fixing part 11. The capture net 21 retracts to capture the target drone 10 and discharges the target drone 10 from the back of the drone body 1, thus completing the capture and release.

[0067] Reset phase: After the release action is completed, the spare net 21 of the storage net device 2 is pushed to the unfolded position by the net-setting drive device 3, locking the fixing part 11 and the assembly part 22, so that the system is restored to the ready-to-capture state and can perform the next capture operation.

[0068] Therefore, the innovative structural design and working mechanism of the net-capturing drone system in this embodiment of the invention effectively solve the core technical bottlenecks faced by traditional net-capturing drones, and achieves efficient, reliable and economical target drone capture capability.
