[0029] In order to make the person skilled in the art more clear and definite the technical scheme of the utility model, the utility model is described in further detail below in conjunction with the embodiment and the drawing, but the implementation of the utility model is not limited to this.

[0030] As Figures 1-7 Shown, the comprehensive system of unmanned plane investigation and countermeasure based on single scene area provided by this embodiment, the single scene area includes multiple by inside to outside sequentially arranged prevention and control area, these prevention and control area is multiple nested arrangement area, sequentially includes core area, countermeasure area, warning area and control area.

[0031] The comprehensive system includes the area assembly corresponding to each prevention and control area, these area assemblies sequentially include core area assembly, countermeasure area assembly, warning area assembly and control area assembly.

[0032] Core area assembly, countermeasure area assembly, warning area assembly and control area assembly all include investigation group and countermeasure group. That is, each prevention and control area is equipped with corresponding investigation group and countermeasure group, can realize the corresponding unmanned plane investigation and countermeasure of each prevention and control area.

[0033] Each investigation group includes multiple investigation equipment, is used to find and locate different types of potential threat unmanned plane in coordination. Here multiple refers to at least two investigation equipment, so as to form more comprehensive investigation ability in single prevention and control area.

[0034] Each countermeasure group includes multiple countermeasure devices for corresponding countermeasures after the discovery of the above unmanned aerial vehicles. The multiple here refers to at least two countermeasure devices, so as to counter different types of unmanned aerial vehicles in a single control area.

[0035] Through the cooperation of multiple detection devices and countermeasure devices in each control area, various types of unmanned aerial vehicle threats can be dealt with in a single scene area. This design forms a comprehensive and targeted comprehensive system for unmanned aerial vehicle detection and countermeasures, effectively improving the countermeasure effect on the target unmanned aerial vehicle.

[0036] In one embodiment, the countermeasure group of the core area component is the first countermeasure group 10. The first countermeasure group 10 includes a countermeasure shield, a full-band mobile countermeasure vehicle, a micro-interference unmanned aerial vehicle, and a navigation deception device.

[0037] Among them, the countermeasure shield is a portable device that can quickly interfere with the target unmanned aerial vehicle at close range. The full-band mobile countermeasure vehicle works in cooperation with the micro-interference unmanned aerial vehicle. The full-band mobile countermeasure vehicle is responsible for large-scale interference, while the micro-interference unmanned aerial vehicle is targeted to approach and interfere with specific targets. The navigation deception device makes the target unmanned aerial vehicle deviate from the original flight route by sending false navigation signals.

[0038] In one embodiment, the countermeasure group of the countermeasure area component is the second countermeasure group 20. The second countermeasure group 20 includes a first directional countermeasure device, a first omnidirectional countermeasure device, and a countermeasure gun.

[0039] Among them, the first directional countermeasure device precisely interferes with unmanned aerial vehicles in a specific direction; the first omnidirectional countermeasure device interferes with the surrounding area in all directions; and the countermeasure gun is a portable device that can precisely attack a single unmanned aerial vehicle at close range. The design of this combination of multiple devices enables the second countermeasure group 20 to flexibly cope with various unmanned aerial vehicle threat scenarios in the countermeasure area.

[0040] In this embodiment, the first directional countermeasure device includes a fixed directional countermeasure device and a mobile directional countermeasure device. This combination design improves the flexibility and adaptability of the comprehensive system, and can better cope with different types of unmanned aerial vehicle threats in the countermeasure area.

[0041] The fixed directional countermeasure device is usually installed on the top of a building, a tower or other fixed structure, and can cover a preset specific direction and area.

[0042] The mobile directional countermeasure device can be installed on a vehicle or designed as a portable device, and can quickly adjust the coverage direction and area as needed.

[0043] The fixed directional countermeasure equipment provides stable basic protection, while the mobile directional countermeasure equipment supplements the mobility and responsiveness of the comprehensive system in the countermeasure area. The combination of the two types of directional countermeasure equipment enables the comprehensive system to ensure continuous protection of the countermeasure area while also having the ability to respond quickly and be deployed flexibly.

[0044] In this embodiment, the first omnidirectional countermeasure equipment includes a full-band countermeasure equipment and a partial-band countermeasure equipment. This design allows the operator of the monitoring center to flexibly select the most suitable countermeasure strategy according to different threat situations and environmental requirements.

[0045] The full-band countermeasure equipment can simultaneously cover multiple frequency bands, including but not limited to common UAV control and image transmission frequency bands such as 2.4 GHz and 5.8 GHz, in order to deal with various types of UAVs using different frequency bands.

[0046] The full-band countermeasure equipment can simultaneously interfere with the control signal, image transmission signal, and navigation signal of the UAV. Due to the need to cover multiple frequency bands simultaneously, the power consumption is generally high.

[0047] When facing unknown types or multiple types of UAV threats, when comprehensive prevention and control is required in important occasions, and when the environment allows for a larger power output, the full-band countermeasure equipment can be used in the countermeasure area.

[0048] The partial-band countermeasure equipment can perform directional interference on a specific frequency band or several frequency bands. Its characteristics are that it only interferes with specific frequency bands, has low power consumption, can accurately interfere with known types of UAVs, and can reduce interference with non-target frequency bands and reduce the impact on other legal wireless devices.

[0049] When facing known threat UAV operating frequency bands, when long-term continuous countermeasures are required, and when the electromagnetic environment is sensitive, the partial-band countermeasure equipment can be used in the countermeasure area.

[0050] The combination of the two omnidirectional countermeasure equipment provides comprehensive protection capabilities for the countermeasure area and is suitable for dealing with complex and variable threats.

[0051] In the countermeasure area, the operator can select to enable the full-band countermeasure equipment or the partial-band countermeasure equipment in the area, or use both types of equipment simultaneously, based on the information provided by the reconnaissance group in the area, in order to achieve the best countermeasure effect.

[0052] In one embodiment, the countermeasure group of the warning area component is a third countermeasure group 30. The third countermeasure group 30 includes a second directional countermeasure equipment and a second omnidirectional countermeasure equipment.

[0053] The second directional countermeasure equipment is similar in function to the first directional countermeasure equipment. The second omnidirectional countermeasure equipment is similar in function to the first omnidirectional countermeasure equipment. The design of such a multi-equipment combination enables the third countermeasure group 30 to flexibly cope with various unmanned aerial vehicle threat scenarios in the alert area.

[0054] In this embodiment, the second directional countermeasure equipment includes fixed directional countermeasure equipment and mobile directional countermeasure equipment. This design is similar in function to the first directional countermeasure equipment of the second countermeasure group 20.

[0055] The fixed directional countermeasure equipment of the second directional countermeasure equipment is usually installed on commanding heights on the boundary of the alert area, such as the top of a high-rise building.

[0056] The mobile directional countermeasure equipment of the second directional countermeasure equipment is usually installed on a dedicated countermeasure vehicle, which has strong mobility and can quickly adjust the coverage direction and range to fill the coverage blind area of the fixed equipment.

[0057] The use of the fixed directional countermeasure equipment and the mobile directional countermeasure equipment of the second directional countermeasure equipment in combination with the reconnaissance group of the alert area enables the comprehensive system to achieve comprehensive and flexible countermeasure capabilities in a larger alert area.

[0058] In this embodiment, the second omnidirectional countermeasure equipment includes full-band countermeasure equipment and partial-band countermeasure equipment. This design is similar in function to the first omnidirectional countermeasure equipment of the second countermeasure group 20.

[0059] When multiple unknown types of unmanned aerial vehicle threats appear in the alert area, or when comprehensive protection of the entire alert area is required during major activities or special periods, the full-band countermeasure equipment of the alert area can be used.

[0060] When long-term continuous countermeasures are required but energy consumption needs to be controlled, or when the electromagnetic environment is sensitive, precise control of the interference range is required, the partial-band countermeasure equipment of the alert area can be used.

[0061] The use of the full-band countermeasure equipment and the partial-band countermeasure equipment of the alert area in combination with the reconnaissance group of the alert area enables the operators in the monitoring center to flexibly select the most suitable countermeasure strategy according to different threat situations and environmental requirements. For example, in daily alerting, the partial-band countermeasure equipment may be mainly used for routine protection, while the full-band countermeasure equipment is started for rapid response when unknown threats are found or comprehensive protection is required.

[0062] In one embodiment, the fourth countermeasure group 40 includes third directional countermeasure equipment, third omnidirectional countermeasure equipment, and a reconnaissance and attack integrated countermeasure gun.

[0063] The third directional countermeasure equipment is similar to the first directional countermeasure equipment in function, and is used for directional interference at the boundary of the control area to prevent unauthorized UAVs from entering the control area.

[0064] The third omnidirectional countermeasure equipment is similar to the first omnidirectional countermeasure equipment in function, and is used for omnidirectional interference in a large range of the control area, and quickly establishes a large range of "no-fly zone" when necessary. The all-in-one countermeasure gun is provided to the patrol personnel in the control area, and is used for responding to sudden and local UAV threats.

[0065] In this embodiment, the third directional countermeasure equipment includes fixed directional countermeasure equipment and mobile directional countermeasure equipment. This design is similar to the first directional countermeasure equipment and the second directional countermeasure equipment in function.

[0066] The fixed directional countermeasure equipment of the fourth countermeasure group 40 is suitable for long-term and continuous monitoring and countermeasures at the boundary of the control area, especially for potential threats at a long distance.

[0067] The mobile directional countermeasure equipment of the fourth countermeasure group 40 is suitable for responding to dynamic threats in the control area.

[0068] The combination of the fixed directional countermeasure equipment and the mobile directional countermeasure equipment of the fourth countermeasure group 40 and the investigation group of the control area enables the operator of the monitoring center to achieve comprehensive and flexible countermeasure capability in the control area. For example, when the investigation group of the control area detects a suspicious target at a long distance, the fixed directional countermeasure equipment in the area can be immediately used for directional interference, and the nearest mobile directional countermeasure equipment in the area can be mobilized to the possible intrusion path for interception.

[0069] In this embodiment, the third omnidirectional countermeasure equipment includes full-band countermeasure equipment and partial-band countermeasure equipment. This design is similar to the first omnidirectional countermeasure equipment and the second omnidirectional countermeasure equipment in function.

[0070] When it is necessary to shield the control area in a large range of electromagnetic environment, or when it is necessary to establish a large range of "no-fly zone" in major activities or special periods, the full-band countermeasure equipment of the control area can be used.

[0071] In the sensitive area of the electromagnetic environment of the control area, the partial-band countermeasure equipment of the control area can be used when it is necessary to accurately control the interference range and frequency band.

[0072] The full-band and partial-band countermeasures devices of the fourth countermeasure group 40 and the combination with the investigation groups of the control zones enable the operators of the monitoring center to flexibly select the most suitable countermeasure strategy according to different threat levels and electromagnetic environment requirements. For example, in daily control, the partial-band countermeasures devices of the control zones are mainly used for routine protection, while in the case of large-scale intrusion or the need for overall blockade, the full-band countermeasures devices of the control zones are started for rapid response.

[0073] In one embodiment, the investigation groups include TDOA devices for determining the positions of the drones by analyzing the time difference of the arrival of drone signals at different receivers, AOA devices for locating the drones by measuring the angle of arrival of the drone signals, photoelectric detection devices for visually identifying and tracking the drones using optical and thermal imaging techniques, and protocol cracking devices for analyzing and decoding the communication protocols between the drones and the remote controllers to obtain more information about the drones.

[0074] These investigation devices work together to form a comprehensive and multi-level investigation network: the TDOA and AOA devices provide preliminary positioning information of the target drones, covering a large area; the photoelectric detection devices accurately track and identify the drones based on the position information provided by the TDOA and AOA devices; and the protocol cracking devices provide detailed information about the target drones to assist in judging their potential threats.

[0075] In this way, the investigation groups of each control area can effectively deal with drones with potential threats in complex environments.

[0076] In one embodiment, the comprehensive system further includes a control device in communication connection with the investigation groups and the countermeasure groups of each control area. The control device maintains real-time connection with the investigation groups and the countermeasure groups through a high-speed and secure communication network. The control device is the monitoring center (platform) responsible for overall management of the work of all investigation groups and countermeasure groups.

[0077] Based on the above embodiment, taking an international sports event as an example, the event is held in a large stadium, and the surrounding areas include the athlete village, the news center, and other facilities.

[0078] In this case, the comprehensive system can take the large stadium as the core zone and monitor the stadium and its surrounding airspace all day round and in all directions to timely discover drones with potential dangers. The investigation groups located in each control area start the countermeasure groups of the corresponding control areas according to the threat level and position of the unauthorized drones.

[0079] For the drones discovered in the core zone, full-band interference and micro interference drones can be immediately started for interception. When suspicious drones are discovered in the countermeasure zones and the alert zones, directional countermeasures devices are used for accurate strikes, and if necessary, the full-band countermeasures are upgraded.

[0080] When large-scale UAV activities are found in the control area, precise strikes can be carried out through the detection and attack integrated countermeasure gun, and the full-band countermeasure equipment in the area is started to establish a large-range electromagnetic shield.

[0081] It can be seen that the comprehensive system of the above embodiments can provide comprehensive and efficient UAV prevention and control for key areas or key units, and maximize the protection of low-altitude safety.

[0082] The above is only further embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art within the scope disclosed by the present application, according to the technical scheme and concept of the present application, equivalent replacement or change, all belong to the protection scope of the present application.
