Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) countermeasure devices, and more specifically to a box-type portable unmanned aerial vehicle (UAV) countermeasure device. Background Art

[0002] In terms of application scenarios, drone anti-control devices can usually be divided into fixed, vehicle-mounted and portable types. In terms of technical routes, drone anti-control devices can usually be divided into general detection devices based on radio reception and spectrum recognition, message parsing detection devices based on radio reception and protocol decoding, drone suppression devices based on radio interference, and drone deception devices based on satellite signal generation. Portable drone anti-control devices are mainly drone suppression guns (gun type) and suppression shields (plate type), which are usually composed of a signal source, a power amplifier, an antenna, and a battery. There are also some drone detection and strike guns and detection and strike shields with composite detection functions, which are usually composed of a receiver, a display screen, a signal source, a power amplifier, an antenna, and a battery. Fixed drone anti-control devices can usually provide more complex functions, but they must be used in conjunction with a server. The rapid development of drone technology in recent years has brought more challenges to drone countermeasures, including increased communication link frequency band occupancy, improved anti-interference performance of communication links, and the use of mobile communication networks for link communications (hereinafter referred to as network connections). To solve the problem of increased drone communication link frequency bands, it is necessary to increase the corresponding "signal source, power amplifier, and antenna". To solve the problem of improved anti-interference performance of communication links, it is necessary to increase the transmission power. To solve the problem of using mobile communication networks for link communications, it is necessary to use navigation deception (mobile communication networks cannot perform interference suppression). Either method will lead to problems such as increased device size and weight, making it no longer suitable for handheld use and unavailable. Utility Model Content

[0020] In summary, the box body 1 is closed at ordinary times, and the omnidirectional receiving antenna group 8 is folded or disassembled and stored in the box body 1. It can be charged by the mains or on-board. When in use, it is carried to the working position by a vehicle or a person, the box body 1 is opened, the omnidirectional receiving antenna group 8 is installed, and the device is turned on. The equipment monitors the drone signal within the horizontal 360° range in real time. When a "black flying" drone is detected, the device high-definition touch screen 6 displays a warning interface or uses a built-in sound generating device to emit a prompt sound (compared with existing devices, this monitoring process does not require human intervention). For some drones that can perform message parsing (some models of DJI), decoding is performed to directly obtain the drone serial number, location, and pilot location, and provide them to the user through the display screen. The user assesses the threat and determines different disposal methods such as finding the pilot, disposing of the drone, or tracking the flight behavior. For drones that cannot perform message parsing and the target is not within the line of sight, the user switches to the target direction finding mode, and the device allocates a directional antenna array to the RF receiving unit 16, cooperates with the user to rotate the device, and determines the direction of the drone by the strength of the received signal. For targets within the line of sight or targets with a determined direction, the drone needs to be disposed of. When the device is turned on, the user rotates the device to align with the target direction, turns on the radio interference function, and transmits an interference signal with the same frequency band as the detection signal (compared with common devices, it does not need to be held by the user after it is turned on). For situations where the radio interference is turned on for a period of time and the suppression of the drone signal is unsuccessful (mainly networked machines), the navigation deception function can be turned on to achieve no-fly, denial, directional expulsion and other controls. Therefore, the box-type portable drone countermeasure device adopts a box-type structure design, which is easy to carry, has an ordinary appearance, is concealed and not aggressive, and is suitable for low-altitude protection in multiple scenarios such as land, rooftops, driving, and ships. It also reasonably utilizes the space of box 1 to integrate drone detection, analytical positioning, interference suppression, and navigation deception functions, solving the problem that the current common countermeasure equipment has a single function and a small number of controlled drones. It fully utilizes the space of box 1 to integrate a large-capacity rechargeable battery, solving the problem of insufficient battery life of the current countermeasure device. When using radio suppression, it only needs to manually adjust the direction of the device to work continuously. During the launch, the omnidirectional detection antenna design avoids the common gun-type reconnaissance and countermeasure units, and the problem that personnel must hold the device in circles to complete the drone search.
