Description

Technical Field

[0001] This utility model belongs to the technical field of drone countermeasure equipment, specifically relating to a dedicated countermeasure equipment for unmanned, fully automatic drones. Background Technology

[0002] With the rapid development of the domestic and international civilian drone market, while bringing convenience to people, a series of safety hazards have also been exposed. Cases of civilian drones flying illegally occur from time to time, causing a series of public safety risks.

[0003] Currently, most existing drone countermeasures, especially in urban environments, employ independent detection and countermeasures. Neither the detection nor the countermeasure equipment is capable of 24 / 7 monitoring; they are only deployed during specific mission phases. This repeated deployment and retrieval increases equipment wear and tear and wastes manpower. The operational process involves detection personnel notifying the countermeasure team of the drone's signal and location. Once in position, the countermeasure team activates its jamming device to intercept the drone. This method demands high levels of equipment sensitivity and coordination across all operational stages. Furthermore, the wide variety of detectors and countermeasures, with varying technical levels, leads to frequent misjudgments, missed detections, and ineffective countermeasures, resulting in wasted human and financial resources. Moreover, most equipment lacks upgrade capabilities, becoming increasingly inadequate in the face of ever-growing numbers of new drones and frequencies.

[0004] Based on this, a dedicated countermeasure device for unmanned, fully automatic drones is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a dedicated countermeasure device for unattended fully automatic drones, in order to address the shortcomings of the prior art mentioned above.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an unattended fully automatic drone-specific countermeasure device, including a gallium nitride interference countermeasure module array, a source signal identification and processing module, a spectrum detection module, a network control unit, and a drone information spectrum library; The gallium nitride interference countermeasure module array, spectrum detection module, network control unit, and UAV information spectrum library are respectively connected to the signal recognition and processing module. The spectrum detection module is used to detect radio signals emitted by the UAV and its control system, identify the information characteristics of the radio signals, and send the information characteristics to the source signal identification and processing module. The source signal identification and processing module is used to compare and analyze the information characteristics of the detected radio signals with the information characteristics of UAVs in the UAV information spectrum library; determine the UAV model to which the radio signals belong; and send a warning prompt to the operator of the countermeasure device through the network control unit; at the same time, activate the countermeasure jamming module of the corresponding frequency band in the gallium nitride jamming countermeasure module array, and transmit countermeasure jamming signals to the UAV through the antenna array.

[0007] As a further explanation of this utility model, the UAV information spectrum library contains the information characteristics of radio signals of commercially available civilian UAVs, and can update the information characteristics of UAV radio signals in real time through the network control unit.

[0008] As a further explanation of this utility model, the gallium nitride interference countermeasure module array is composed of multiple groups of gallium nitride high-power countermeasure interference modules in different frequency bands. According to the instructions of the source signal identification and processing module, the countermeasure interference module in the corresponding frequency band is activated to transmit interference signals to counter the UAV.

[0009] As a further explanation of this utility model, the gallium nitride interference countermeasure module array is also connected to an antenna array, which consists of multiple sets of antennas in different frequency bands and is used to transmit UAV interference signals.

[0010] As a further explanation of this utility model, the gallium nitride interference countermeasure module array is also provided with an expansion interface, through which the interference countermeasure frequency band is updated.

[0011] As a further explanation of this utility model, it also includes a power supply module and a heat dissipation module; The power supply module is used to connect the mains power to the countermeasures equipment for power supply; The heat dissipation module is electrically connected to the power supply module to dissipate the heat generated during the operation of the gallium nitride interference countermeasure module array, the source signal identification and processing module, the spectrum detection module, and the UAV information spectrum library.

[0012] This utility model has the following advantages compared with the prior art: The countermeasure device in this utility model has the function of detecting unattended operation, and can autonomously complete the prevention and countermeasure against most commercially available drones. It adopts a database information comparison method for accurate countermeasure, with high sensitivity and good accuracy, effectively reducing the false judgment and missed judgment rate. It adopts a gallium nitride countermeasure interference module, which has the advantages of high power, small size and light weight.

[0013] The countermeasure device in this invention can be upgraded by uploading new UAV spectrum information through the network control unit. In terms of hardware, a gallium nitride high-power countermeasure interference module can be added through the expansion interface to increase the countermeasure frequency, reduce the need for separate equipment upgrades, and thus save equipment procurement costs.

[0014] This utility model has the functions of single-machine operation and multi-machine networking. It can be portable for temporary setup or fixed for long-term deployment. It can be used for single-point control or multi-machine linkage, making it suitable for multi-task and multi-scenario use.

Detailed Implementation

[0017] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] like Figure 1 As shown, this utility model provides a technical solution: a dedicated countermeasure device for unattended fully automatic drones, including a gallium nitride interference countermeasure module array 1, a source signal identification and processing module 4, a spectrum detection module 5, a network control unit 6, and a drone information spectrum library 7; The gallium nitride interference countermeasure module array 1, spectrum detection module 5, network control unit 6, and UAV information spectrum library 7 are respectively connected to the signal recognition and processing module 4 and integrated into the fuselage base with an aluminum alloy support frame design. This ensures light weight, sufficient structural strength, and excellent heat conduction and heat dissipation. In addition, the equipment shell is made of fiberglass and the outer surface is painted white to reduce heat absorption in outdoor environments.

[0019] The fiberglass shell will not affect the reception and transmission of radio signals. The sturdy shell ensures that the core electronic equipment is not damaged by adverse external environments such as rain, dust, and strong light. It can also effectively prevent damage to electronic equipment from external forces and accidental contact by personnel. Facing many adverse factors such as wind, sun, rain, humidity, heat, cold, and dust, it is waterproof, moisture-proof, and lightweight.

[0020] The spectrum detection module 5 is used to detect the radio signals emitted by the UAV and its control system, identify the information characteristics of the radio signals, and send the information characteristics to the source signal identification and processing module 4; the UAV information spectrum library 7 contains the information characteristics of the radio signals of commercially available civilian UAVs, and can update the information characteristics of the UAV's radio signals in real time through the network control unit 6. Specifically, the UAV information spectrum library 7 stores the radio signal spectrum information of remote control, data transmission, and image transmission of most commercially available civilian UAVs and assembled UAVs. It also stores the spectrum information of most commercially available remote control devices, data transmission devices, and image transmission devices. The design covers the following frequency bands: 72MHz, 433MHz, 900MHz, 1.2GHz, 2.4GHz, and 5.8GHz. The collected spectrum information is used to retrieve the collected spectrum information at any time and hand it over to the source signal processing module. The spectrum is then compared with the UAV signal spectrum detected by the spectrum detection module 5 to confirm the specific UAV model corresponding to the detected radio signal.

[0021] The network control unit 6 is used for wireless signal detection and interference control of drones, remote control of drones by operators, human-machine information interaction, networking communication between devices, equipment upgrades, and remote updates of information in the drone information spectrum database 7.

[0022] The source signal identification and processing module 4 is used to compare and analyze the information characteristics of the detected radio signal with the information characteristics of the UAV in the UAV information spectrum library 7; determine the UAV model to which the radio signal belongs; and send a warning to the operator of the detected UAV through the network control unit 6; at the same time, activate the anti-jamming module of the corresponding frequency band in the gallium nitride interference countermeasure module array 1, and transmit anti-jamming signals to the UAV through the gallium nitride interference countermeasure module array 1.

[0023] The gallium nitride (GaN) jamming countermeasure module array 1 is an array composed of multiple groups of high-power GaN jamming countermeasure modules in different frequency bands. According to the instructions of the source signal identification and processing module 4, the corresponding frequency band of the high-power GaN jamming countermeasure module is activated, and jamming signals are emitted to counter the drone. The high-power GaN jamming countermeasure modules are divided into frequency bands of 72MHz, 433MHz, 900MHz, 1.2GHz, 2.4GHz, and 5.8GHz. According to the instructions of the source signal identification and processing module, the corresponding frequency band of the jamming countermeasure module is activated, and jamming signals are emitted to counter the drone.

[0024] Gallium nitride (GaN) modules have the advantages of small size, light weight, and high power, which greatly reduces weight and size compared to traditional countermeasure modules.

[0025] The gallium nitride high-power anti-jamming module array has an expansion interface, through which new frequency band anti-jamming modules can be added.

[0026] Furthermore, the gallium nitride high-power anti-interference module generates high temperatures during operation, necessitating the installation of a fan for forced air cooling. To achieve both effective heat dissipation and ensure the core electronic equipment remains in a sealed environment, this embodiment incorporates a metal airflow duct. High-heat-generating components, such as the gallium nitride high-power anti-interference module, are installed close to the metal airflow duct to enhance heat conduction. The fan forces airflow through the metal airflow duct to dissipate heat from the high-heat-generating components. Since the cooling airflow only enters and exits through the airflow duct and does not enter the equipment's interior, external adverse factors such as moisture and dust will only enter and exit the airflow duct and will not damage the core electronic equipment.

[0027] The gallium nitride interference countermeasure module array 1 is also connected to an antenna array 8, which consists of multiple antennas of different frequency bands and is used to transmit UAV interference signals.

[0028] Antenna array 8 consists of multiple antennas in the 72MHz, 433MHz, 900MHz, 1.2GHz, 2.4GHz and 5.8GHz frequency bands, which are connected to the gallium nitride high-power anti-jamming modules in the corresponding frequency bands in gallium nitride jamming module array 1, and are used to transmit UAV jamming signals.

[0029] As one implementation method in this embodiment, it also includes a power supply module 2 and a heat dissipation module 3; The power supply module 2 is used for mains power connection to the countermeasures equipment to provide power, and can be left unattended for a long time.

[0030] The heat dissipation module 3 is electrically connected to the power supply module 2 to dissipate the heat generated during the operation of the gallium nitride interference countermeasure module array 1, the source signal identification and processing module 4, the spectrum detection module 5, and the UAV information spectrum library 7, so as to ensure that the entire system of the equipment is at the normal operating temperature.

[0031] In practical use, it includes stand-alone mode and network mode; In standalone mode, the drone control equipment provides effective coverage of a single point within a 2km radius. 2 In drone control scenarios, the network control unit 6 connects to a dedicated network platform, allowing operators to remotely control the drone management equipment via computer or mobile app. In network mode, at least two drone control devices are deployed at fixed locations. The drone control devices deployed through the network control unit 6 are connected to a dedicated network platform to achieve large-area, blind-spot-free drone prevention and control.

[0032] In standalone mode, the drone control equipment can be operated manually or automatically.

[0033] When operating manually, the drone signal detection is performed independently. After discovering the information characteristics of the drone's radio signal, the network control unit 6 can send a warning prompt to the operator of the drone control equipment, wait for the operator's subsequent instructions, and determine whether to activate the gallium nitride interference countermeasure module array 1 to interfere with the drone. Alternatively, after discovering the information characteristics of the drone's radio signal, the source signal identification and processing module 4 can determine the drone model to which the radio signal belongs, and then directly activate the gallium nitride interference countermeasure module array 1 to interfere with the drone.

[0034] During automatic operation, the system automatically detects the information characteristics of the drone's radio signals and, based on the detected information characteristics of the drone's radio signals, activates the gallium nitride interference countermeasure module array 1 to interfere with and counter the drone.

[0035] In networked mode, operators of drone management equipment can control the equipment for 24 / 7 fully automated monitoring, enabling drone detection or detection and countermeasure operations.

[0036] In network mode, the real-time location of the detected drone or its operator can be locked through multi-drone linkage detection by drone control equipment.

[0037] It should be further explained that the accompanying drawings and embodiments of this utility model mainly describe the concept of this utility model.
