Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an anti-unmanned aerial vehicle power spinning flying rope net capture device and a control method thereof. Background Art

[0002] With the popularization and application of civil drones, the phenomena of "illegal flying" and "abuse of drones" have been repeatedly banned, while the research on technical countermeasures against drones in low-altitude airspace is still relatively blank. The countermeasures against drones are related to social stability and public safety, and are an urgent social need at present.

[0003] Anti-UAV systems developed at home and abroad are mainly divided into two categories: electromagnetic or optical interference and physical capture. Electromagnetic interference refers to the use of electromagnetic or optical interference with UAV signals, which may affect normal communications in the surrounding area; optical interference refers to the use of optical principles and technical means to interfere with key components such as the UAV's visual system, navigation system or sensor, thereby weakening or destroying the normal function of the UAV to achieve its defense or control; physical capture such as high-energy laser or impact methods has the disadvantages of high cost and low reuse rate. The capture net system proposed in this patent is suitable for reconnaissance of enemy UAVs that need to be recovered, and has been widely used in recent years. Foreign anti-UAV capture net systems such as Drone Catcher are mainly in the form of a huge capture net launched from the air that can be quickly deployed and wrap the target UAV, but it has the problems of large size, heavy weight and slow speed.

[0004] After searching, the invention patent application of Chinese patent application number 2019108363222 discloses an aerial anti-UAV net-catching device. By designing a recovery parachute at the rear end of the flying net, and the recovery parachute is pulled out by the flying net, the bow-pulling mechanism of the recovery parachute is omitted, and the net-catching device can be recovered at the same time. The patent includes multiple functional compartments from the head to the tail, which are launched from an aerial platform, with a wide capture range, a long interception distance, and high capture accuracy. However, the device has a complex and compact structure, is difficult to manufacture, has a high cost, and uses pyrotechnics, which reduces the safety and stability of the product.

[0005] After searching, the utility model patent of Chinese patent application No. 2019203219220 is a new intelligent net capture anti-UAV system, including a base, an intelligent variable speed gimbal, a launch unit and a target detection and aiming unit. The system has an innovative and efficient disposal method, a high degree of intelligence, can capture all-weather, is safe and efficient to use, has strong adaptability and is easy to maintain. However, the installation of the device on an aerial platform is difficult and can only be used on a vehicle-mounted mobile platform or a fixed site.

[0006] The above technical solution has the following defects and shortcomings:

[0007] (1) Low speed and maneuverability: Existing drone interceptors are heavy and large in size, which makes the carrier aircraft have no speed advantage and makes it difficult or impossible to complete the task of chasing small flying drones (the speed can reach about 45m / s at a higher speed).

[0008] (2) High equipment cost: A high-performance netting system requires advanced launching devices, net materials, and tracking and aiming technologies, all of which will significantly increase the manufacturing cost of the system.

[0009] (3) Equipment safety and reliability are low: Net-catching devices that rely on high-pressure air guns or pyrotechnics to launch have certain safety hazards during the transportation stage, and the net-catching launch effect is greatly affected by temperature, and its reliability needs to be improved. Summary of the invention

[0010] The purpose of the present invention is to provide an anti-UAV powered spinning rope net capture device and a control method thereof, which solves the problems of low speed and maneuverability, high equipment cost, and low equipment safety and reliability in the prior art.

[0011] To achieve the above-mentioned purpose, the present invention provides an anti-UAV powered spinning rope net capture device, comprising a UAV body body, wherein the UAV body body is fixed on the top of a frame, a fairing is installed on the top of the UAV body body, and arms equipped with motor mechanisms are arranged at the four corner edges of the UAV body body. A ranging module, a main control module and a relay module are integrated in the UAV body body, and each of the motor mechanisms is connected to a capture net arranged inside the fairing through a traction rope.

[0012] Preferably, the fairing is made of engineering plastic or 3D printing material with strong impact resistance, non-magnetic or weak magnetic properties, and includes an upper cover and a lower cover, the upper cover and the lower cover are fastened together by a micro electromagnetic lock structure, and a servo is also installed on the outer surface of the lower cover.

[0013] Preferably, the motor mechanism includes an electromagnetic block and a magnetic isolation plate installed on the top of the electromagnetic block, wherein the magnetic isolation plate is connected to the brushless motor through a ball bearing, and a propeller is arranged on the top of the brushless motor. The brushless motor is a common model of brushless motor on the market, which drives the propeller to rotate when the drone is in normal working state, providing power for the drone to fly. The electromagnet is used to provide magnetic force, which is composed of a common model of power-off type electromagnet on the market. It can provide about 1kg of suction to ferromagnetic materials when the power is off, and loses the suction when the power is on. The electromagnet is a cylinder with a threaded hole at the bottom, which is always bolted to the fuselage. The magnetic isolation plate has the function of attracting the electromagnet when the power is on, isolating the electromagnet from the brushless motor to prevent the magnetic force of the electromagnet from affecting the normal working state of the brushless motor when the power is on. It is made of silicon steel or Permalloy with strong ferromagnetism. There are holes on the magnetic isolation plate, which is always bolted to the brushless motor. At the same time, there are fixing buckles around the magnetic isolation plate. When the magnetic isolation cylinder is attracted to the electromagnet in the vertical direction, the fixing buckles are used to limit the freedom of its horizontal movement.

[0014] Preferably, a parachute is provided on one side of the bottom of the frame, which is composed of the Flyfire parachute recovery product Manti or a similar product having an autonomous opening function when the drone descends.

[0015] Preferably, the fishing net is made of Zailon material, has a quadrilateral net shape and quadrilateral mesh, and the mesh size is 30×30 cm.

[0016] Preferably, a small metal ring is added to the side of the ball bearing, and the four corners of the fishing net are fixedly connected to each of the small metal rings through the traction rope. The geometric center of the fishing net has a traction rope of about 1m that is always connected to the geometric center of the frame, so that the fishing net is still connected to the fuselage after it flies out, making it easy for the opened parachute to drive both of them to land safely at the same time.

[0017] A control method for an anti-UAV powered spinning rope net capture device comprises the following steps:

[0018] S1. When the interceptor is flying normally, the circuits where the four electromagnets are located attract the magnetic isolation plate. At this time, the capture net is not released. Four capture net traction ropes extend from the cabin and are distributed above the four arms of the hunting drone frame. The capture net is folded into a triangle in the same way as a parachute is folded, and then rotated and folded along the horizontal and vertical axes respectively;

[0019] S2. When the distance measurement module of the fuselage detects that the distance between the chasing drone and the chased drone is less than or equal to the set value, the distance measurement module sends a signal to the main control module, and the main control module causes the electromagnetic lock of the lower cover of the fairing to lose its suction through level control, so that the upper cover of the fairing is separated from the lower cover, exposing the net device in the fairing, and at the same time, the circuit where the electromagnet is located is turned on;

[0020] S3, after the electromagnet circuit is turned on, the electromagnet loses its attraction to the magnetic isolation plate. At this time, the four motors are released from the vertical direction and detached from the UAV frame. The drone continues to fly out quickly by relying on the remaining lift of the propeller. Each propeller, brushless motor, net ring and magnetic isolation plate act as a mass block to pull the capture net to unfold, so that the net covers and entangles the target, causing the target to lose power and fall.

[0021] S4. Since the geometric center of the capture net is connected to the interceptor fuselage, the two fall together. After the parachute module detects the falling trend of the fuselage, the parachute quickly pops out from the side and opens, driving the capture net device, the captured drone and the interceptor to land safely.

[0022] Preferably, in step S1, the circuit where the four electromagnets are located is composed of electromagnets, batteries, and relay switches. Since the electromagnets are powered by batteries and the switches controlled by relays are disconnected, the electromagnets have an attractive force to attract the magnetic isolation plate.

[0023] Preferably, in step S2, the step of connecting the circuit where the electromagnet is located is:

[0024] The main control module uses level control to change a pin that originally outputs a high level or a low level to output a low level or a high level, so that the relay switch connected to the output end is closed, and the circuit where the electromagnet is located is turned on.

[0025] Therefore, the present invention adopts an anti-UAV power spinning rope net capture device and a control method thereof of the above structure, which has the following beneficial effects:

[0026] (1) The present invention uses a motor-driven spinning structure to release a capture net to intercept drones. Compared with the traditional anti-drone system that uses a net and a missile to deal with low altitudes, the present invention can capture low, medium and high altitude drones. It is flexible and maneuverable, and the deployment area of ​​the capture net is large, which can adapt to targets of various sizes and has low requirements on hardware and algorithm complexity.

[0027] (2) The present invention can utilize a small-sized flying drone to carry a simple-structured netting mechanism, which is lighter and more compact, thus ensuring that the anti-UAV interceptor can reach and exceed the speed of a small-sized flying drone (about 50 m / s). It is also easy to carry and suitable for deployment in cities.

[0028] (3) The present invention uses a power-off type electromagnetic release device. Compared with using a spring, a high-pressure gas cylinder, an electromagnetic gun or an ignition device, the device is simple, can reduce weight, and improves the safety and stability of the device.

[0029] (4) The invention uses an integrated landing and recovery device, which connects the geometric center of the capture net and the interceptor fuselage so that after the capture net is deployed and the target is successfully captured, the capture net, the target and the interceptor fuselage fall synchronously; at this time, the parachute is deployed to achieve synchronous and smooth landing and recovery of all components.

[0046] Example

[0047] like Figure 1-11 The present invention provides an anti-UAV powered spinning rope net capture device, including a UAV body body 12, which is fixed on the top of a frame 8, a fairing 9 is installed on the top of the UAV body body 12, and arms 13 equipped with motor mechanisms are arranged at the four corner edges of the UAV body body 12. The UAV body body 12 is integrated with a ranging module, a main control module and a relay module, and each motor mechanism is connected to a capture net 10 arranged inside the fairing 9 through a traction rope 11.

[0048] The fairing 9 is made of engineering plastic or other 3D printed materials with strong impact resistance, non-magnetic or weak magnetic properties. The upper and lower covers are buckled together by a micro electromagnetic lock structure. During normal flight, the upper and lower covers are locked together, and the space inside the lower cover contains the folded capture net. The fairing is used to protect the key power mechanism of the anti-UAV power spinning rope net capture system, while making the interceptor less subject to resistance during high-speed flight, providing better aerodynamic effects, and achieving the expected flight performance. A servo 3 is also installed on the outer surface of the lower cover.

[0049] The motor mechanism includes an electromagnetic block 2 and a magnetic isolation plate 5 installed on the top of the electromagnetic block 2. The magnetic isolation plate 5 is connected to the brushless motor 1 through a ball bearing 6. A propeller 4 is arranged on the top of the brushless motor 1. The brushless motor 1 is a common model of brushless motor 1 on the market. When the drone is in normal working state, it is powered on to drive the propeller to rotate and provide power for the drone to fly. The electromagnetic block 2 is used to provide magnetic force. It is composed of a common model of power-off type electromagnet on the market. It can provide about 1kg of suction force to ferromagnetic materials when the power is off, and loses the suction force when the power is on. The electromagnetic block 2 is a cylinder with a threaded hole at the bottom, which is always bolted to the fuselage. The magnetic isolation plate 5 has the function of attracting the electromagnetic block 2 when it is powered on, isolating the electromagnetic block 2 from the brushless motor 1 to prevent the magnetic force of the electromagnetic block 2 from affecting the normal working state of the brushless motor 1 when it is powered on. It is made of silicon steel or Permalloy with strong ferromagnetism. There are holes on the magnetic isolation plate 5, which is always bolted to the brushless motor 1. At the same time, there are fixing buckles around the magnetic isolation plate 5. When the magnetic isolation cylinder is attracted to the electromagnetic block 2 in the vertical direction, the fixing buckles are used to limit the freedom of its horizontal movement.

[0050] A parachute 7 is arranged on one side of the bottom of the frame 8, which is composed of the Flyfire parachute recovery product Manti or a similar product with an autonomous opening function when the drone descends.

[0051] The capture net 10 is made of Zailon material, has a quadrilateral net shape and quadrilateral mesh, and the mesh size is 30×30 cm.

[0052] A small metal ring is installed on the side of the ball bearing 6, and the four corners of the capture net 10 are fixedly connected to each small metal ring through a traction rope 11. The geometric center of the capture net 10 has a traction rope 11 of about 1m that is always connected to the geometric center of the frame 8, so that the capture net 10 is still connected to the main body 12 of the drone after it flies out, so that the opened parachute 7 can drive the two to land safely at the same time.

[0053] A control method for an anti-UAV powered spinning rope net capture device comprises the following steps:

[0054] S1. When the interceptor is flying normally, the circuit where the four electromagnetic blocks 2 are located is composed of an electromagnet, a battery, and a relay switch. The electromagnet has an attractive force because the battery is powered and the switch controlled by the relay is disconnected, so the electromagnet has an attractive force, which attracts the magnetic isolation plate 5. At this time, the capture net 10 is not released, and the four capture net traction ropes 11 extend from the cabin and are distributed above the four arms of the pursuit frame 8. The capture net 10 is folded into a triangle in the way that a parachute is folded, and then rotated and folded along the horizontal and vertical axes respectively;

[0055] S2, when the distance measuring module of the drone fuselage body 12 detects that the distance between the chasing drone and the chased drone is less than or equal to the set value, the distance measuring module sends a signal to the main control module, and the main control module causes the electromagnetic lock of the lower cover of the fairing to lose suction through level control, so that the upper cover and the lower cover of the fairing 9 are separated, exposing the capture net 10 in the fairing 9, and at the same time, the circuit where the electromagnetic block 2 is located is turned on;

[0056] S3, after the circuit of the electromagnetic block 2 is connected, the electromagnetic block 2 loses its attraction to the magnetic isolation plate 5. At this time, the four brushless motors 1 are released from the constraints in the vertical direction, separated from the frame 8, and rely on the remaining lift of the propeller 4 to continue to fly out quickly. Each propeller 4, the brushless motor 1, the small metal ring and the magnetic isolation plate 5 act as a mass block to pull the capture net 10 to unfold, so that the net covers and entangles the target, causing the target to lose power and fall;

[0057] S4. Since the geometric center of the capture net is connected to the interceptor drone fuselage body 12, the two fall together. After the parachute module detects the falling trend of the drone fuselage body, the parachute 7 quickly pops out from the side and opens, driving the capture net 10, the captured drone and the interceptor to land safely.

[0058] The servo 3 is composed of a small AS0017 servo or a similar product with a geometric size of only about 10 mm, which provides the mechanical energy required to open the fairing at the moment when the motor module flies out, and indirectly drives the ejection mechanism to work smoothly.

[0059] The ball bearing 6 is made of a material such as stainless steel, and a small metal ring is added to the side. When in use, the traction rope of one corner of the quadrilateral net 10 is wound and tied in the small ring, and the main body of the ball bearing 6 is nested and engaged with the outside of the brushless motor 1. On the one hand, the net ring can rotate freely relative to the vertical axis of the brushless motor 1. Therefore, after the brushless motor 1 is ejected from the fuselage, when the brushless motor performs complex movements in space, the flexible relative rotation of the inner and outer rings of the ball bearing 6 can ensure that the direction of the traction rope 11 is basically stable and unchanged, and the traction rope 11 will not be entangled with the brushless motor 1 or the propeller 4 and other components; on the other hand, together with the magnetic isolation plate 5, the horizontal height of the traction rope 11 is limited to be higher than the bottom surface of the brushless motor 1, so that the net 10 will not be separated from the brushless motor device.

[0060] The parachute 7 is composed of the Flyfire parachute recovery product Manti or a similar product that has an autonomous opening function when the drone descends. It is fixed on the frame 8 of the drone. When the interceptor releases the power device and starts to fall, the parachute 7 can be opened from the side without affecting the opening of the capture net 10 directly above the fuselage or being entangled with it, thereby driving the capture net 10, the captured drone and the interceptor to land safely.

[0061] The distance measuring module is composed of a distance sensor, the main control module is composed of a flight control board, and the relay module is composed of a relay that uses a pin level of the main control module as an input signal to control the on-off of the electromagnet circuit.

[0062] Therefore, the present invention adopts the above-mentioned anti-UAV power spinning rope net capture device and its control method, controls the electromagnet circuit to be turned on through a relay, causes the electromagnet to instantly lose suction, and realizes the rapid, synchronous, and accurate release of four brushless motors; uses the brushless motor as the power source for the net to unfold, drives the net to unfold and cover the target. The magnetic isolation plate not only attracts the electromagnet when the electromagnet is powered off to fix the four corners of the net on the UAV, but also effectively isolates the influence of the electromagnet on the brushless motor during the whole process to ensure flight stability.

[0063] The present invention fixes a traction rope at one corner of the catching net on a small ring of a ball bearing, and installs the ball bearing on the outside of a brushless motor, so that the net ring can rotate freely, keeping the direction of the traction rope of the catching net stable and avoiding entanglement with the motor or propeller; at the same time, the ball bearing and the magnetic isolation plate jointly ensure the height of the traction rope of the catching net and prevent the catching net device from being separated from the motor.

[0064] The geometric center of the capture net and the geometric center of the interceptor fuselage are always connected by a traction rope, so that after the capture net captures the target, the capture net, the target and the interceptor fuselage fall synchronously; at this time, the parachute is deployed to achieve synchronous and safe landing of all components, thereby realizing the recovery function.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
