Anti-electromagnetic-interference anti-unmanned-aerial-vehicle catching device

Abstract

The invention provides an anti-electromagnetic-interference anti-unmanned-aerial-vehicle catching device comprising a head, a tail, a small wing and a propeller structure. A catching device control system is arranged in the head and comprises an information collection module, a control unit and a propeller motor. The information collection module comprises an image collection module, a laser radarscanning module and a close-range electromagnetic wave detection module. The image collection module, the laser radar scanning module and the close-range electromagnetic wave detection module are connected with the control unit. The propeller motor is connected with the propeller structure. The tail is arranged behind the head and is internally provided with a catching net. The small wing is arranged at the head and is connected with the control unit. A compensating circuit is further arranged in the catching device and can conduct opposite offsetting with electromagnetic wave, received by the close-range electromagnetic wave detection module, of the propeller motor of the catching device. The anti-electromagnetic-interference anti-unmanned-aerial-vehicle catching device can catch an unmanned aerial vehicle accurately, thus the escape possibility of the target unmanned aerial vehicle is low, interference is smaller, and catching is more accurate.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to an anti-drone capture device. Background technique [0002] As more and more drones appear in people's lives, some drones that do not follow the rules often cause troubles to others and even affect public safety. In order to prevent the illegal misuse of drones, a new thing has emerged: anti-drone systems. [0003] The existing anti-drone means mainly include interference and blocking, direct destruction and monitoring and control. The interference blocking type is to interfere with all the signals of the target UAV by emitting specific electromagnetic wave signals, so that the signal of the UAV is cut off, and the UAV is triggered to return. The countermeasures of this type of method are poor; The laser cannon directly shoots down the UAV. This kind of method has strong countermeasures, but the UAV shot down is easy to cause damage to the ground personnel; the monitoring and control ca...

The interference blocking type is to interfere with all the signals of the target UAV by emitting specific electromagnetic wave signals, so that the signal of the UAV is cut off, and the UAV is triggered to return. The countermeasures of this type of method are poor; The laser cannon directly shoots down the UAV. This kind of method has strong countermeasures, but the UAV shot down is easy to cause damage to the ground personnel; the monitoring and control category mainly uses hacking technology to invade the UAV’s operating system, hijack the radio control, and put Captured by UAVs, the technical content and technical cost of such methods are high, and it is difficult to popularize

Nowadays, a kind of capture device for intercepting drones is gradually emerging. The capture device captures the target drone by launching net bombs or using the drone to carry the interception frame. After the net bombs are launched, they can only rely on inertial flight and cannot be adjusted. In terms of flight angle, the target drone is easy to escape, the capture rate is low, and there is a danger of falling and hurting people; while the target drone is intercepted by the drone carrying the interception frame, since the drone carries the interception frame, its speed It is difficult to surpass the target UAV, and the flexibility of movement is poor, the capture rate is low, and the practicability is poor
