Description

Technical Field

[0001] The present invention relates to the technical field of defense equipment control, and particularly to a portable control method and system for unmanned aerial vehicle (UAV) defense equipment. Background Art

[0002] UAV defense equipment refers to a dedicated system or device used to detect, identify, track, and respond to illegal UAV intrusions, aiming to ensure airspace security, personnel safety, information security, and facility security. Such equipment is widely used in sensitive areas such as concert venues and large event areas.

[0003] In actual use, when the defense equipment is activated, the intruding UAV will have its remote control signal cut off, causing it to lose navigation and positioning information. However, this may trigger the default "lost connection response mechanism" in the intruding UAV, such as hovering, returning, or crashing directly. However, in complex airspace or urban environments, the positioning signal is not stable. If the interference is too strong or the target UAV does not have a safe return mechanism, it is very likely that the intruding UAV will crash directly, affecting the safety of equipment and personnel.

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0027] In Embodiment 1, Figure 1 The implementation process of the portable UAV defense equipment control method provided by the embodiment of the present invention is shown, and the details are as follows: S100: Define the defense area of the UAV, traverse the possible signal sources within the defense area, configure the characteristic data of the signal sources, where each signal source corresponds to at least one piece of characteristic data, integrate the signal sources and the characteristic data, and generate a characteristic library.

[0028] Define the airspace range that needs to be monitored and protected, that is, the defense area. The defense area can be a performance venue or a public activity area. Conduct a comprehensive scan and traversal of all possible signal sources within the defense area. The signal sources include audience terminal devices, performance communication systems, broadcast devices, and legitimate UAVs, etc. Extract and configure the characteristic data of each signal source. The characteristic data includes but is not limited to: operating frequency, modulation method, signal strength, and time characteristics, etc. Establish the corresponding relationship between each signal source and the characteristic data, integrate all the corresponding relationships, and generate a characteristic library. The characteristic library is mainly used to quickly identify the communication signals of illegal UAVs and improve the response efficiency of the defense equipment.

[0029] S200: Activate several spectrum analyzers pre-deployed in the defense area, collect spectrum data, compare with the characteristic library, determine whether there is a data link of an illegal UAV. If so, select the video transmission signal of the illegal UAV from the data link, estimate the approximate position, activate the built-in radio frequency module in the UAV defense equipment, and interfere with the video transmission signal.

[0030] According to the actual resource allocation or monitoring arrangement, a number of spectrum analyzers are pre-deployed within the defense area. A spectrum analyzer is an electronic test device capable of measuring and analyzing radio spectrum signals. Using the spectrum analyzer, the spectrum data within the defense area is collected in real time, including information such as frequency, bandwidth, modulation mode, signal strength, and time-domain characteristics, and a spectrum scan map is generated. The collected spectrum data is compared with a pre-established feature library to identify whether there are signals in the spectrum data that conform to the characteristics of illegal drone data links.

[0031] If so, the frequency bands and signal types that conform to the characteristics of illegal drone video transmission signals are screened out from the captured data links. Using the multi-point positioning algorithm in the existing technology and combining the spectrum data in the multiple deployed spectrum analyzers, the approximate spatial position of the illegal drone is deduced. Activate the radio frequency module integrated inside the portable drone defense device. The radio frequency module refers to an electronic device specifically used to transmit interfering radio signals. It can block or interfere with the normal transmission of the target communication link by generating interference waves, noise signals, or forged signals within a specific frequency range, so that the drone operator cannot receive a clear image backhaul. It should be noted that this process does not affect the flight control system of the drone and there is no risk of crashing. At the same time, it effectively weakens the reconnaissance and monitoring functions of the illegal drone, further improving the use effect of the defense device.

[0032] S300: Generate a takeoff instruction via the approximate position and send it to the drone for driving away. Using the binocular vision camera integrated in the drone for driving away, collect the disparity map containing the illegal drone, verify the data link, locate the relative coordinates of the illegal drone, calculate the offset value, generate an offset route, and make real-time adjustments to the offset route. When the illegal drone is at the center of the disparity map and the offset value is less than the preset threshold, activate the visual interference rule pre-embedded in the drone for driving away.

[0033] Generate a takeoff instruction, where the takeoff instruction includes the approximate position of the illegal drone, the takeoff position of the drone for driving away, and the flight path planning, etc. Send the takeoff instruction to the drone for driving away. After receiving the takeoff instruction, the drone for driving away starts the takeoff procedure and flies according to the planned flight path. During the flight, the drone for driving away will continuously use its own sensors and vision system to track the illegal drone, and make real-time adjustments to the heading and altitude to ensure that it can stably approach the illegal drone and implement subsequent interference.

[0034] Among them, the drone for driving away is equipped with a binocular vision camera. The binocular vision camera consists of two cameras installed side by side with slightly different viewing angles. By simultaneously capturing two images of the same scene and using the parallax principle, the depth information and three-dimensional spatial positions of various objects in the images are calculated. Using the binocular vision camera in the drone for driving away, two images with slightly different viewing angles are synchronously collected to generate a parallax map containing the illegal drone, and the three-dimensional spatial position and distance of the illegal drone relative to the drone for driving away are calculated. According to the calculation results, the data link of the illegal drone is verified, where the verification refers to: determining whether the illegal drone actually exists, verifying whether the approximate position is correct, etc. According to the three-dimensional spatial position and distance of the illegal drone relative to the drone for driving away, combined with the real-time position of the drone for driving away, the relative coordinates of the illegal drone are calculated. The relative coordinates are: the spatial position coordinates of the illegal drone relative to the drone for driving away, that is, taking the drone for driving away as the coordinate origin, and the position of the illegal drone is represented by the numerical values of the three axes X, Y, and Z. Through the relative coordinates, the offset value is calculated. The offset value is the distance that the drone for driving away needs to move in the X, Y, and Z axis directions to reach below the illegal drone.

[0035] Using the offset value, an offset route is generated, and the drone for driving away is controlled to fly according to the offset route, and the offset route is adjusted in real time according to the relative coordinates. When the binocular vision camera detects that the illegal drone is exactly located at the center position of the parallax map and the current offset value is less than the preset threshold, it means that the drone for driving away reaches the area directly below the illegal drone (it may not be located on the vertical projection), and the built-in visual interference rule is immediately activated. The visual interference rule includes: controlling the drone for driving away to emit strong stroboscopic lights, lasers or other optical signals.

[0036] In this application, by controlling the drone for driving away to fly to the area directly below the illegal drone and performing visual interference, the normal shooting of the illegal drone is affected, forcing the illegal drone to return. In actual operation, the positions where the drone for driving away performs visual interference should also include: other interference positions on the connection line between the illegal drone and the performance center (or other main positions). Whether the drone for driving away is located below the illegal drone or at other interference positions, when the drone for driving away emits stroboscopic lights, the strong and frequent flashing lights will directly interfere with the shooting effect of the illegal drone's camera, resulting in serious jitter, blurring or complete occlusion of the image in its video transmission signal, and finally making the illegal drone lose the meaning of shooting and forcing it to return.

[0037] In Embodiment 2, Figure 2The implementation process of the control method for the portable UAV defense device provided by the embodiments of the present invention is shown. The following details the steps of demarcating the defense area of the UAV and traversing the possible signal sources within the defense area, as follows: S101: Split the signal sources into static signals and mobile signals, and define the signal source corresponding to the data link as the target source.

[0038] The signal sources are divided into static signal sources and mobile signal sources. Static signals refer to devices with fixed positions and stable communication parameters, such as performance audio, surveillance cameras, broadcast systems, and Wi-Fi hotspots, etc. The transmission frequency band, power, and position of such devices remain basically unchanged during the entire performance or event; while mobile signals include smart terminals, legal UAVs, and wearable devices carried by the audience, etc.; the signal source corresponding to the data link is defined as the target source, where the data link refers to the communication signal suspected to be that of an illegal UAV.

[0039] S102: Determine whether the target source is a mobile signal. If so, integrate all the mobile signals, generate a warning list, and send it to a preset terminal.

[0040] Determine whether the target source is a mobile signal. If so, integrate all the mobile signals, generate a warning list, which is the set of all communication signals suspected to be those of illegal UAVs, and send the warning list to a preset terminal, where the preset terminal is the terminal of the UAV defense device management personnel.

[0041] In Embodiment 3, Figure 3 The implementation process of the control method for the portable UAV defense device provided by the embodiments of the present invention is shown. The following details the steps of activating several spectrum analyzers pre-deployed in the defense area, collecting spectrum data, comparing it with the feature library, and determining whether there is a data link of an illegal UAV, as follows: S201: Configure the deployment position of the mimic controller, synchronize the data link to the mimic controller, and generate a handshake signal.

[0042] Deploy the mimic controller at communication relay points and edge computing units, etc. within the defense area. The mimic controller can simulate the characteristics of legal communication links and construct false interaction channels; transmit the spectrum data of the data link (communication frequency, modulation method, data packet structure, signal timing characteristics, etc.) to the mimic controller; after receiving the spectrum data, the mimic controller actively initiates a simulated interaction with the data link to generate a handshake signal.

[0043] S202: Send the handshake signal to the signal source, receive the feedback signal, and re-define the illegal UAV.

[0044] After the handshake signal is sent, the mimic controller continuously monitors the response behavior of the signal source, receives and analyzes the feedback signal returned by it. The feedback signal may include content such as an acknowledgment response, rejection, silence, or intention to continue communication. By obtaining the feedback signal, it is possible to further confirm whether the signal source is an illegal drone and avoid making ambiguous judgments based solely on spectrum data.

[0045] In Embodiment 4, Figure 3 The implementation process of the control method for the portable drone defense device provided by the embodiment of the present invention is shown. The following details the steps of selecting the video transmission signal of the illegal drone and calculating the approximate position, as follows: S203: Integrate all spectrum analyzers to generate a collaborative processing architecture and embed a multi-point positioning algorithm.

[0046] Utilize all spectrum analyzers to generate a collaborative processing architecture. The collaborative processing architecture connects the data acquisition modules, signal processing modules, control nodes, etc. of each spectrum analyzer through a network, thereby realizing data synchronization, task allocation, and sharing of processing results among multiple devices. Embed a multi-point positioning algorithm into the collaborative processing architecture to achieve rapid positioning of the illegal drone.

[0047] S204: Integrate the collaborative processing architecture and the video transmission signal to calculate the approximate position.

[0048] Based on the spectrum data received by multiple spectrum analyzers, combined with time of arrival, time difference of arrival, or phase difference, etc., use the multi-point positioning algorithm to calculate the approximate position of the illegal drone.

[0049] In this embodiment, it is only necessary to calculate the approximate position of the illegal drone. Subsequently, through the visual positioning of the drone to be driven away, the approximate position of the illegal drone is refined, and refinement means reducing the error range.

[0050] In Embodiment 5, Figure 3 The implementation process of the control method for the portable drone defense device provided by the embodiment of the present invention is shown. The following details the steps of activating the built-in radio frequency module in the drone defense device and performing signal interference on the video transmission signal, as follows: S205: Determine the frequency band where the video transmission signal is located, construct an interference range, and input it into the radio frequency module.

[0051] Determine the frequency band of the video transmission signal, specifically including data such as the center frequency, bandwidth, and upper and lower boundary frequencies, and construct an interference range, where the interference range refers to the frequency interval covered by the radio frequency interference signal. Input the interference range into the radio frequency module. After receiving this instruction, the radio frequency module will be immediately activated and transmit interference signals according to the interference range, thereby interfering with the video transmission signal of illegal drones and causing the interruption or serious degradation of their image transmission.

[0052] S206: Divide the defense area into several dangerous intervals, edit the disposal rules corresponding to the dangerous intervals one by one, locate the dangerous interval where the approximate position is located, and trigger the corresponding disposal rules.

[0053] Divide the defense area into several small blocks, and each small block is a dangerous interval. Create a corresponding disposal rule for each dangerous interval. The disposal rule is the specific method for dealing with illegal drones within the divided block. The disposal rules include: early warning notification, flight restriction, decoy return, and forced landing, etc.

[0054] For example, when an illegal drone enters a dangerous interval in an area far from the performance or activity center, activate the corresponding disposal rule, where the disposal rule is: send a warning notice to the managers of the drone defense equipment to prompt the appearance of an illegal drone, facilitating further manual observation and decision-making.

[0055] In Embodiment 6, Figure 4 The implementation process of the portable drone defense equipment control method provided by the embodiment of the present invention is shown. The following details the step of generating a takeoff instruction via the approximate position and sending it to the drone to be repelled, as follows: S301: Collect the spatial distribution information in the defense area, draw a building distribution map, and mark the risk points.

[0056] Obtain the distribution data of various buildings, structures, and terrain features in the area, that is, the spatial distribution information, from the building facility management party in the defense area, and generate a building distribution map, marking the risk points therein. The risk points include: important safety protection facilities, management centers, or energy supply areas, etc.

[0057] S302: Construct a virtual fence via the risk points and embed a trigger mechanism.

[0058] With the risk point as the center and a preset distance as the radius, construct a virtual fence. The virtual fence is a three-dimensional electronic boundary. When an illegal drone (approximate position) enters the virtual fence, activate the trigger mechanism, where the trigger mechanism is the emergency treatment method for ground equipment or personnel; for example, activate the warning device to remind ground personnel to stay away from the ground area corresponding to the virtual fence.

[0059] In Embodiment 7, different from Embodiment 1, in the embodiment of the present invention, the method further includes: Update the approximate location according to a preset frequency and mark it on the building distribution map; Connect all the approximate locations to generate an intrusion route, find out the take-off point, and send it to a preset terminal.

[0060] Update the approximate location of the illegal drone according to a preset frequency. The preset frequency can be once per minute. Mark the updated approximate location on the building distribution map. Connect all the approximate locations to generate a continuous intrusion route, which reflects the complete flight trajectory of the illegal drone from entering the defense area to the current location; find out the suspected take-off point and send the take-off point to a preset terminal to facilitate the timely handling by the management personnel of the drone defense equipment.
