Description

Technical Field

[0001] This invention relates to the technical field of maritime security, specifically to an intelligent countermeasure system and method for unmanned aerial vehicles (UAVs) applied to islands. Background Technology

[0002] With the transformation and development of drone technology, people's demand for drones is increasing, but the problems brought about by this are also becoming more and more prominent.

[0003] For example, drones bring convenience to users in areas such as high-altitude photography and aerial payloads. However, a series of safety issues brought about by drones, such as invading others' privacy, unauthorized modification of drones for cargo transport, and drone smuggling, have raised concerns about drones.

[0004] To prevent the leakage of target and location information, it is necessary to counter drones. Currently, most anti-drone systems (or drone countermeasure systems) on the market are based on land defense technology and can only perform soft-kill actions such as electromagnetic interference to drive them away and forced landings, resulting in poor countermeasure effectiveness. Summary of the Invention

[0005] In view of this, it is necessary to provide a smart countermeasure system and method for drones that can be applied to islands with better countermeasure effects.

[0006] This invention provides an intelligent countermeasure system for unmanned aerial vehicles (UAVs) applied to islands, comprising: a monitoring and early warning subsystem, a countermeasure subsystem, and a control subsystem;

[0007] The monitoring and early warning subsystem is used to obtain target information of suspicious targets through various detection methods;

[0008] The control subsystem is used to receive target information of suspicious targets, make threat judgments based on the target information, and determine countermeasure targets; when there are one or more countermeasure targets in the area, it evaluates the handling priority of the countermeasure targets and generates a handling sequence list of countermeasure targets.

[0009] The countermeasure subsystem is used to receive the disposal sequence list of the countermeasure target, invoke the pre-set countermeasure strategy according to the disposal sequence list, countermeasure the countermeasure target, and send the countermeasure result to the control subsystem.

[0010] The disposal sequence list includes: a countermeasure target number, a threat assessment result corresponding to the countermeasure target number, and a priority disposal sequence number corresponding to the countermeasure target number and the threat assessment result;

[0012] Optionally, the control subsystem includes:

[0013] The update module is used to update the disposal sequence list according to the preset update time or emergency disposal instructions, and send the updated disposal sequence list to the countermeasure subsystem so that the countermeasure subsystem can perform countermeasure operations according to the updated disposal sequence list.

[0020] The navigation deception module is used to induce a drone to make an emergency landing by employing navigation deception techniques.

[0022] Optionally, the control subsystem is also used to acquire island environmental information, and based on the island environmental information, to enable the monitoring and early warning subsystem to use different detection methods to acquire target information of suspicious targets, and to enable the countermeasure subsystem to use different countermeasure procedures to counter the countermeasure targets.

[0023] Optionally, in the control subsystem, based on island environmental information, the monitoring and early warning subsystem employs different detection methods to obtain target information of suspicious targets, and the countermeasure subsystem employs different countermeasure procedures to counter the targets; including:

[0024] The marine environment assessment module is used to determine the level of the marine environment based on the island's environmental information. When the marine environment level is good, it sends the first detection signal to the monitoring and warning subsystem and the first countermeasure signal to the countermeasure subsystem.

[0025] When the marine environment level is unfavorable, a second detection signal is sent to the monitoring and early warning subsystem, and a second countermeasure signal is sent to the countermeasure subsystem.

[0026] The first detection signal is used to enable the spectrum detection module, radar detection module, and photoelectric detection module in the monitoring and early warning subsystem to detect suspicious targets.

[0027] The second detection signal is: to enable the spectrum detection module and radar detection module in the monitoring and early warning subsystem to detect suspicious targets;

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, but 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.

[0056] Example 1

[0057] See Figure 1 A smart anti-drone system for islands includes: a monitoring and early warning subsystem 10, a countermeasure subsystem 20, and a control subsystem 30.

[0058] The monitoring and early warning subsystem 10 is used to obtain target information of suspicious targets through various detection methods;

[0059] The control subsystem 30 is used to receive target information of suspicious targets, make threat judgments based on the target information, and determine countermeasure targets; when there are one or more countermeasure targets in the area, it evaluates the handling priority of the countermeasure targets and generates a handling sequence list of countermeasure targets.

[0060] The countermeasure subsystem 20 is used to receive the disposal sequence list of the countermeasure target, invoke the pre-set countermeasure strategy according to the disposal sequence list, countermeasure the countermeasure target, and send the countermeasure result to the control subsystem.

[0061] The disposal sequence list includes: a countermeasure target number, a threat assessment result corresponding to the countermeasure target number, and a priority disposal sequence number corresponding to the countermeasure target number and the threat assessment result;

[0062] The countermeasure strategy includes: a threat assessment result level and a corresponding countermeasure procedure.

[0063] It should be noted that the monitoring and alert subsystem 10 in this embodiment includes multiple detection methods, each with a different working principle. In the detection of suspicious targets, it can make up for the shortcomings of a single method and improve the accuracy of the detection of suspicious targets.

[0064] In this embodiment, the monitoring and alerting subsystem 10 includes:

[0065] Spectrum detection module 101 is used to acquire frequency and azimuth information of suspicious targets;

[0066] Radar detection module 102 is used to acquire altitude, distance and speed information of suspicious targets;

[0067] The photoelectric detection module 103 is used to acquire shape information, azimuth information and elevation information of suspicious targets.

[0068] It should be noted that the photoelectric detection module can be a three-band detection module, including: visible light, mid-wave infrared and far-infrared imagers; in addition, the photoelectric detection module can integrate AI image algorithms, and through the integrated AI image algorithms combined with traditional image processing, high-speed and high-precision single target tracking, video target detection and segmentation, and multi-target tracking can be achieved.

[0069] In this embodiment, the countermeasure procedure includes:

[0070] Electromagnetic interference module 201 is used to interfere with and drive away drones using electromagnetic interference methods.

[0071] Navigation deception module 202 is used to induce a drone to make an emergency landing by employing navigation deception methods;

[0072] The laser countermeasure module 203 is used to destroy or strike drones using laser means.

[0073] It should be noted that the laser countermeasure module can be a high-energy laser anti-drone device, capable of blinding or destroying drones with lasers.

[0074] The various countermeasures in this embodiment can take corresponding countermeasures against drones based on the threat assessment result level (such as: jamming and driving away, deceiving landing, and destroying and attacking), thereby improving the accuracy of countermeasures.

[0075] In this embodiment, target information of suspicious targets is obtained through multiple means, which improves the accuracy of suspicious target detection. At the same time, the control subsystem performs threat assessment on the acquired target information of suspicious targets to determine countermeasure targets. When there are one or more countermeasure targets in the area, the priority of countermeasure targets is evaluated and a countermeasure target disposal sequence list is generated. This enables the countermeasure subsystem to countermeasure targets (drones) according to the disposal sequence list, which can prioritize the countermeasure against drones with higher threats, thereby improving the accuracy and effectiveness of countermeasures.

[0076] Example 2

[0077] See Figure 2Based on Embodiment 1, a smart anti-drone system for islands is provided. In this embodiment, the control subsystem 30 includes:

[0078] The update module 40 is used to update the disposal sequence list according to the preset update time or emergency disposal instruction, and send the updated disposal sequence list to the countermeasure subsystem 20 so that the countermeasure subsystem 20 can perform countermeasure operations according to the updated disposal sequence list.

[0079] It should be noted that the emergency response instructions can be issued by back-end staff, or automatically issued by the control subsystem 30 when the threat assessment result of a newly added suspicious target corresponds to the highest priority level.

[0080] In this embodiment, the update module can ensure that high-risk countermeasure targets are prioritized for countermeasures, thereby improving the accuracy of countermeasures and increasing the efficiency of response.

The control subsystem 30 is also used to acquire island environmental information, and based on the island environmental information, to enable the monitoring and early warning subsystem 10 to use different detection methods to acquire target information of suspicious targets, and to enable the countermeasure subsystem 20 to use different countermeasure procedures to counter the countermeasure targets.

[0083] In this embodiment, the control subsystem 30 can be connected to the marine environment monitoring system 50 via a network connection device to obtain island environment information provided by the marine environment monitoring system 50.

[0084] It should be noted that the aforementioned island environmental information may include: electromagnetic data, meteorological data, and surrounding airspace intelligence data of the target area.

[0085] In this embodiment, the control subsystem 30 acquires island environmental information, and based on this information, enables the monitoring and early warning subsystem 10 to use different detection methods to acquire target information of suspicious targets, and enables the countermeasure subsystem 20 to use different countermeasure procedures to counter the targets; including:

[0086] The marine environment judgment module 301 is used to judge the level of the marine environment based on the island environmental information. When the level of the marine environment is good, it sends a first detection signal to the monitoring and warning subsystem 10 and a first countermeasure signal to the countermeasure subsystem 20.

[0087] When the marine environment level is unfavorable, a second detection signal is sent to the monitoring and early warning subsystem 10, and a second countermeasure signal is sent to the countermeasure subsystem 20.

[0089] The second detection signal is to enable the spectrum detection module 101 and radar detection module 102 in the monitoring and early warning subsystem 10 to detect suspicious targets;

[0090] The first countermeasure signal is to cause the electromagnetic interference module 201, navigation deception module 202, and laser countermeasure module 203 in the countermeasure subsystem 20 to counter the target.

[0091] The second countermeasure signal is to cause the electromagnetic interference module 201 and the navigation deception module 202 in the countermeasure subsystem 20 to counter the target.

[0092] In this embodiment, the control subsystem 30 is connected to the marine environment monitoring system 50 via a network connection device to obtain island environment information provided by the marine environment monitoring system 50.

[0093] In this embodiment, the existing marine environment monitoring system can be used to acquire island environment information provided by the marine environment monitoring system. This allows the monitoring and early warning subsystem to use different detection methods to obtain target information of suspicious targets, and the countermeasure subsystem to use different countermeasure procedures to counter the countermeasure targets, thereby improving the effectiveness of detection and countermeasure.
