Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically to an anti-UAV device and method. Background Technology

[0002] The earliest unmanned aerial vehicles (UAVs) appeared in the 1960s, then known as "remotely piloted aircraft." After decades of development, these aircraft are now collectively referred to as "unmanned aerial vehicles" (UAVs). Along with the change in name, these aircraft have become increasingly autonomous and intelligent, making them one of the most researched and rapidly developing areas in military equipment and civil aviation in recent years.

[0003] However, with the increasing use of drones, various related violations and illegal incidents have emerged, seriously threatening national military security, civil aviation safety, and public safety. In response to these security issues, various long-range anti-drone devices have appeared on the market. However, these devices are difficult to accurately strike small drones at close range, and suffer from problems such as complex structure, inconvenience in handling them for extended periods, and difficulty in accurately striking at night. Summary of the Invention

[0004] Objective of this invention: The objective of this invention is to provide a tornado-based anti-drone device that can accurately strike small drones at close range, regardless of day or night. Another objective of this invention is to provide an anti-drone method that enables the device to autonomously counter drones.

[0005] Technical solution: In a first aspect, the present invention provides an anti-drone device based on tornadoes, comprising: a control component, a tornado generating component, a sensing component, and an action component, wherein the sensing component is connected to the tornado generating component, and the input terminals of the tornado generating component and the action component are connected to the control component.

[0006] Sensing components are used to identify target drones and obtain the distance between the target drone and anti-drone devices;

[0007] Motion components are used to adjust the orientation of the tornado generating components connected to them through roll and pitch motions;

[0008] Tornado generation component, used to generate tornadoes;

[0009] The control component receives target information perceived by the sensing component and controls the action component and tornado component to work. The control component controls the action component to make the tornado generation component move towards the target drone, and controls the tornado generation component to generate a tornado that shoots down the target drone.

[0010] Furthermore, the tornado generating component includes a power section and a contraction section. The cross-section of the contraction section is smaller than that of the power section. A ducted fan is arranged in the power section to provide airflow. The interior of the contraction section contains a centrifuge and multiple jet pipes to convert the incoming airflow in the ducted fan into a rotating airflow, thereby forming a tornado.

[0011] Furthermore, a guide vane is installed between the power section and the contraction section. The airflow generated by the ducted fan in the power section enters the contraction section through the guide vane. Most of the gas is rotated by the centrifuge device in the contraction section, and the remaining gas is injected into the rotating airflow through the jet pipe to achieve the formation of a tornado.

[0012] Furthermore, the ducted fan is a multi-stage fan.

[0013] Furthermore, the motion assembly includes a circular electric turntable and a U-shaped electric turntable. The circular electric turntable is installed horizontally, and the support plate of the U-shaped electric turntable is installed on the rotating shaft of the circular electric turntable. The circular electric turntable is used to control the rolling motion of the tornado generating assembly, and the U-shaped electric turntable is used to control the pitching motion of the tornado generating assembly.

[0014] Furthermore, the roll motion angle range is 0°-360°; the pitch motion angle range is -90°-90°.

[0015] Furthermore, the sensing components include a lidar and an event camera. The lidar is used to measure the distance between the target drone and the anti-drone device; the event camera is used to identify the target drone.

[0016] Furthermore, it also includes a base and a power supply module. The motion component is mounted on the base, and the power supply module and control component are mounted inside the base. The control component, tornado generation component, sensing component, and motion component are powered by the power supply module.

[0017] Secondly, a method for countering drones is provided for the aforementioned countering drone device, comprising the following steps:

[0018] The sensing components identify the target drone and obtain the distance between the target drone and the anti-drone device;

[0019] Based on the information obtained by the perception component, the control component identifies the target drone and controls the action component to make the tornado generation component move towards the target drone. When the target drone is within the strike range, the control component generates a tornado that is shot at the target drone to shoot it down.

[0020] Beneficial effects: In the anti-drone device of the present invention, the sensing component captures the target drone, the control component controls the action component to make the tornado generating component face the target, and controls the tornado generating component to generate a tornado for precise close-range strike on the target. Simultaneously, the sensing component includes an event camera. Compared to other visual devices, the event camera can accurately identify and capture targets regardless of day or night, enabling the anti-drone device to accurately strike targets regardless of day or night.

[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0027] like Figure 1 , Figure 2 As shown, the present invention discloses an anti-drone device, comprising a base 1, a control component 2, an action component, a tornado generation component, a power supply module 7, and a sensing component 8. The power supply module 7 and the control component 2 are installed within the base. The power supply module 7 supplies power to the action component, control component 2, tornado generation component, and sensing component 8; the control component 2 receives target information sensed by the sensing component and controls the action component and tornado component to operate.

[0028] The actuation assembly consists of a circular electric turntable 3 and a U-shaped electric turntable 4. The circular electric turntable 3 is mounted on the base 1, and the support plate of the U-shaped electric turntable 4 is mounted on the rotating shaft of the circular electric turntable 3. The circular electric turntable 3 controls the rolling motion of the tornado generating assembly, with an angle range of 0°-360°; the U-shaped electric turntable 4 controls the pitch motion of the tornado generating assembly, with an angle range of -90°-90°.

[0029] The tornado generating assembly consists of a power section 5 and a contraction section 6, and is connected to the rotating shaft of the U-shaped electric turntable 4. The power section 5 is equipped with a ducted fan 501 to provide airflow; the contraction section 6 contains a centrifuge 504 and multiple jet pipes 503, which are used to convert the incoming airflow from the ducted fan into rotating airflow, thereby forming a tornado.

[0030] The internal components of a tornado generating component include, for example: Figure 3 As shown, the ducted fan 501 is a multi-stage fan. By controlling the multi-stage fans to generate different wind speed distributions, it can initially induce the intake air to form a vortex. Simultaneously, by controlling the power of the multi-stage fans and the flow ratio, it is beneficial to the formation of a tornado. Secondly, a relatively long flow area is left between the ducted fan and the main flow channel 502, which is conducive to the free development of the vortex and the initial formation of a vortex. After the vortex is initially formed, the high-speed airflow away from the center enters the compression channel through the jet channel 503, providing the vortex with a stronger rotational speed, increasing the intensity of the tornado. At the same time, the high pressure of the main flow nozzle drives the tornado outward. Finally, the centrifuge at the nozzle outlet further strengthens and maintains the vortex intensity of the tornado. Compared with net-trapping anti-drone devices, the tornado strike device can continuously attack target drones, has a larger attack range, can quickly change the attack direction, and can operate continuously for a long time, resulting in a higher success rate. Compared to electromagnetic anti-drone devices, tornado-based strike devices primarily utilize strong vortices to disrupt the drone's flight environment, eliminating the need for strong electromagnetic radiation. Therefore, they have minimal impact on surrounding residential buildings and do not pose a threat to the safety of operators. Furthermore, both net-based and electromagnetic anti-drone devices, due to their directional nature, are ineffective against swarms of drones. Tornado-based strike devices, however, have a large attack range and can quickly shift their attack direction, effectively targeting drone swarms. The entire tornado-generating device has a simple structure and is economical.

[0031] The sensing component 8 is installed in the middle section of the outer surface of the contraction section and consists of a lidar and an event camera. The lidar is used to measure the distance between the target drone and the anti-drone device; the event camera is used to accurately identify and capture the target drone.

[0032] The tornado generating assembly, consisting of the power section 5 and the contraction section 6, mainly generates and launches tornadoes in the following steps:

[0033] The control unit sends operating signals to the tornado generating unit, and the power section provides a relatively stable airflow through ducted fans;

[0034] The airflow passes through the deflector plate to the contraction section. Most of the gas is rotated by the centrifuge device in the contraction section, and the remaining gas is injected into the rotating airflow through the jet pipe, which realizes the formation of the tornado and increases the intensity of the tornado.

[0035] As airflow accumulates within the contraction section, the pressure of the tornado within the contraction section continuously increases. Upon receiving the launch command, the front baffle of the contraction section opens, utilizing the high pressure difference to rapidly launch the tornado and strike the target.

[0036] This application provides an anti-drone method for the aforementioned anti-drone device, comprising the following steps:

[0037] The event camera in the sensing component 8 works around the clock. When the event camera identifies and captures an intruding drone, the control component 2 receives the target orientation information input by the event camera and controls the circular electric turntable 3 and the U-shaped electric turntable 4 to rotate in coordination, so that the outlet of the contraction section 6 in the tornado generating component always faces the target.

[0038] After the event camera captures the intruding drone, the lidar in the perception component 8 measures the distance between the target and the anti-drone device, and the control component 2 receives the target distance information input by the lidar to determine whether the target is within the strike range.

[0039] When the control component 2 determines that the target is within the range of the anti-drone device, the control component 2 controls the power section 5 to generate airflow, which is accelerated through the contraction section 6 and transformed into a tornado, which is then shot toward the target intrusion drone to shoot it down.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
