Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) countermeasure equipment, in particular to a multifunctional mobile platform for detecting, interfering, deceiving, attacking and picking up UAVs. Background Art

[0002] Most drone countermeasures are vehicle-mounted or handheld, cumbersome to deploy and operate, and feature limited functionality. Highly integrated devices are unavailable. Existing drone countermeasures often only offer one or two of the following: drone detection, jamming, decoy, or strike capabilities. They are also unable to retrieve drones that have landed after being struck. These devices must be mounted on a human-operated vehicle or mobile platform, making them incapable of autonomous drone countermeasures.

[0003] At present, under normal circumstances, drone countermeasures equipment adopts a distributed strategy, that is, drone countermeasures are arranged separately in multiple locations. However, this solution has problems such as high funding costs and complex strategy adjustments, and it is often easy to be passive in the game process. The current development of this integrated multi-functional mobile platform is mainly to lay the foundation for the establishment of a dynamic distributed anti-drone system. Through the networking of multiple integrated multi-functional mobile platforms, a dynamic anti-drone system that can be used at the same level as the drone attack strategy is established, and the dynamic distributed anti-drone strategy is launched relying on the versatility of its platform.

DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Example 1

[0029] A multifunctional mobile platform for detecting, jamming, decoying, attacking and picking up drones, see Figures 1-4 , including a mobile platform 1 and a portable reconnaissance and strike device 9 for attacking drones placed on the mobile platform 1; the portable reconnaissance and strike device 9 is placed at the rear end of the mobile platform 1 through a plurality of support frames 1-1, so that the operator can take the portable reconnaissance and strike device 9, and use the portable reconnaissance and strike device 9 to scout and attack drones, so that the drones land on the ground; the support frames 1-1 are fixedly installed on the mobile platform 1, the number of the support frames 1-1 is preferably 2, and the support frames 1-1 are Y-shaped support frames, which are convenient for the operator to take and place the portable reconnaissance and strike device 9.

[0030] Positioning and navigation antennas 2 are symmetrically mounted on both sides of the mobile platform 1, enabling autonomous navigation. Each positioning and navigation antenna 2 is fixedly mounted on the mobile platform 1 via a bracket 2-1. A navigation laser radar 3 is fixedly mounted at the front of the mobile platform 1 (the navigation laser radar 3 is fixedly mounted directly in front of the mobile platform 1 via a connecting bracket 3-1). This radar is used to detect the ground environment for the mobile platform 1, determine whether there are obstacles in front of the mobile platform 1, and guide the mobile platform 1 to bypass any obstacles in front of it.

[0031] The mobile platform 1 is provided with a drone countermeasure antenna 7 and a drone countermeasure controller 8, and the drone countermeasure controller 8 is communicatively connected to the drone countermeasure antenna 7. There are multiple drone countermeasure antennas 7, each of which is fixed to the mobile platform 1 at equal intervals. The drone countermeasure controller 8 is hemispherical and can evenly cover a 360° horizontal range, allowing it to respond to drones from different directions without adjusting the angle. The positioning and navigation antenna 2 is fixedly mounted on the top of the mobile platform 1, and the portable reconnaissance and strike device 9 is fixedly mounted at the rear end of the positioning and navigation antenna 2. The drone countermeasure antenna 7 is fixed between the positioning and navigation antenna 2 and the portable reconnaissance and strike device 9, and the drone countermeasure controller 8 is located at the front end of the positioning and navigation antenna 2.

[0032] The mobile platform 1 is provided with a pickup unit, which includes a robotic arm 4 mounted on the mobile platform 1, a pickup gripper 5 mounted at the end of the robotic arm 4, and a 3D camera 6. The pickup gripper 5, 3D camera 6, and robotic arm 4 are each connected to the drone countermeasure controller 8. The 3D camera 6 is used to determine the position and shape of the drone, providing a reference for the motion path planning of the robotic arm 4. The pickup gripper 5 is used to pick up drones that have landed on the ground. The pickup gripper 5 on the robotic arm 4 cooperates with the 3D camera 6 to accurately and quickly determine and pick up drones. The 3D camera 6 is fixed above the pickup gripper 5 to facilitate the 3D camera 6 to capture drones that have landed on the ground. The robotic arm 4 is a six-axis robotic arm; the 3D camera 6 is fixedly mounted to the robotic arm 4 via a T-shaped mounting plate 6-1.

[0033] Example 2

[0034] On the basis of Example 1, the mobile platform 1 is a crawler-type mobile platform. The crawler-type mobile platform has a large ground contact area, dispersed pressure, is not easy to sink into mud, snow or sand, and is suitable for various terrains.

[0035] Example 3

[0036] Based on Examples 1-2, the workflow of the multifunctional mobile platform includes the following steps:

[0037] Step 1: Power on the multifunctional mobile platform, check the power and duration of the multifunctional mobile platform, and confirm that other operating parameters of the multifunctional mobile platform are normal (no abnormal alarm).

[0038] Step 2: Move the multifunctional mobile platform to the location where countermeasures are required. The drone countermeasure antenna 7 of the multifunctional mobile platform receives radar signals or has a built-in predetermined program (the program is related to the inspection strategy). Turn on the patrol switch on the multifunctional mobile platform, and the multifunctional mobile platform performs airspace exploration.

[0039] Step 3: Use a multifunctional mobile platform to conduct detection, jamming, deception, and strike operations, forcing the drones that enter the airspace to land on the ground without the ability to take off again.

[0040] Detection: Use the drone countermeasure antenna 7 to send a radio signal. When the radio signal hits the object and returns, the above process is repeated and the returned radio signal is compared. The detected drone status is fed back through the comparison result.

[0041] Interference: The drone countermeasure antenna 7 uses the full frequency band (5G band, 2.4G band, etc.) to send a large amount of information, causing congestion of the frequency band information in a certain area, and then causing abnormalities in the regular information exchange, achieving the effect of interference; in addition, when the drone countermeasure antenna 7 transmits a high-power electromagnetic interference signal, it interferes with the drone control chip with electromagnetic waves, causing interference with the drone's signal transmission, thereby affecting the drone's own movement.

[0042] Deception: Utilize the drone's countermeasure antenna 7 to send GPS positioning signals, allowing the drone to receive the GPS positioning signals sent by the multifunctional mobile platform, causing the drone to move according to the GPS positioning signals sent by the multifunctional mobile platform; (Due to wind fluctuations in the drone's position, the GPS positioning signal is needed to correct the drone's spatial position in real time. Therefore, once a false GPS positioning signal appears, the drone will make real-time corrections, thereby being deceived).

[0043] Attack: The attack mainly occurs when a drone is tricked into landing on the ground by technology or when a portable reconnaissance and attack device 9 is manually removed to attack the drone and land on the ground. The drone counter-attack antenna 7 sends the drone's position information to the drone counter-attack controller 8. The drone counter-attack controller 8 sends a control instruction to the 3D camera 6 to perform a visual search for the forced-landing drone. When the 3D camera 6 finds the drone, it uses the method of covering the drone's position coordinate point to locate the drone's position coordinate as the position coordinate of the mobile platform 1. The mobile platform 1 moves to the drone's position and uses its tracks to crush the drone to ensure that the drone has no ability to fly again.

[0044] In step 4, the UAV countermeasure controller 8 sends a control instruction to the robotic arm 4 and the picking gripper 5. Through the cooperation of the robotic arm 4 and the picking gripper 5, the UAV without the ability to go-around is picked up and stored in a designated location.

[0045] Among them, when the multifunctional mobile phone is low on power or needs to be on standby according to the strategy, it automatically navigates back to the charging device to stand by and replenish power.

[0046] Step 5. Steps 1-4 are for the use of a single device. If multiple multifunctional mobile platforms are networked using a wireless network, radar can be used to detect a large number of drones and mark the intrusion direction, angle, altitude, location, and other information of the drones, which is then transmitted to the command center. The command center then sends movement instructions to each multifunctional mobile platform via a specific network segment. The multifunctional mobile platform combines its own location information with the received movement information and dynamically distributes the number of its own team members based on the distribution of drones (for example, if there are five multifunctional mobile platforms and drones enter from three directions, one multifunctional mobile platform will enter from each direction. The number of drones in each direction will be ranked, and one multifunctional mobile platform will be added to the direction with the largest number of drones. At the same time, based on whether there is a trend of drone differentiation in each direction, one multifunctional mobile platform will be added to the direction with the largest number of drones. If drones enter from four directions, one multifunctional mobile platform will enter from each direction. The number of drones in each direction will be ranked, and one multifunctional mobile platform will be added to the direction with the largest number of drones. If two or more directions with the largest number of drones enter at the same time, one multifunctional mobile platform will be added using a comparison and differentiation method). The predetermined strategy is used to enter the designated area separately and execute steps 2-4.

[0047] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0048] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
