Method for capturing small unmanned aerial vehicle by using small unmanned aerial vehicle

Abstract

The invention relates to a method, in particular to a method for capturing a small unmanned aerial vehicle by using the small unmanned aerial vehicle. Relates to the field of space flight and aviation, and is mainly used for capturing small unmanned aerial vehicles for executing secret photography, investigation and object throwing. As a small unmanned aerial vehicle is in the air and a target is small and is not easy to counteract, the current counteracting method is too high in cost and is not suitable for large-area popularization. According to the method, the four unmanned aerial vehicles are connected with the four corners of the giant net, the tracking distance is zero through the tracking mode of the unmanned aerial vehicles, the target unmanned aerial vehicle is rapidly approached through diving, and the giant net holds the target unmanned aerial vehicle; and the target unmanned aerial vehicle stops rotating through winding of a network cable and a propeller of the target unmanned aerial vehicle, so that the target unmanned aerial vehicle flies away through the giant net belt by utilizing tension of the four unmanned aerial vehicles. The method is low in cost, high in success rate and reusable.

Description

TECHNICAL FIELD

[0001] The application relates to a method for capturing a UAV, and belongs to the field of aviation. BACKGROUND

[0002] The UAV is rapidly developed due to its advantages of flying in the air, small size, sensitive operation, load capacity and combination with a high-definition camera. Except for the limitation of flight height of 500 meters and the division of flight restricted areas, there is no other relevant effective legal restriction and punishment measure, which leads to many unsafe factors of the UAV in addition to normal actions. The first kind is used in conflict zones, mainly used for investigation and delivery of explosives. The second kind is used in important target sites or activities, mainly used for investigation and paparazzi. The third kind is used in residential sites, mainly used for paparazzi and invasion of privacy. As can be seen from the above, the application scene and site of the UAV are very extensive, and there are incorrect uses. The current UAV functions are relatively powerful, such as tracking mode, surrounding mode and the like. Moreover, the selling price of the UAV is not very high, which leads to that anyone who wants to can purchase and engage in illegal activities. The UAV can be controlled to fly for dozens of kilometers, and when the UAV is found or destroyed in the execution of illegal activities, it is difficult to find the implementer, which leads to more reckless illegal activities. If the UAV delivers goods from top to bottom, the defense method is more difficult. The current measures to stop or terminate the illegal activities of the UAV are electromagnetic interference and laser weapons. The two methods indeed have good countermeasures, but the cost is huge, and the price of a vehicle is several million, which is too expensive for the UAV. This leads to that although there are countermeasures, they cannot be widely promoted. The method is to use the UAV to counter the UAV, and the main technologies used are tracking technology and coordination technology of the UAV. The countermeasure principle is to make the target UAV lose power or be strongly pulled to lose the ability of autonomous flight. SUMMARY

[0003] The present application provides a method for capturing unmanned aerial vehicles, which is easy to operate, low in cost, reusable and can be widely promoted. The equipment used in the method is an unmanned aerial vehicle and a giant net. Four unmanned aerial vehicles are connected with the four corners of the giant net, and the giant net is suspended in the air by the unmanned aerial vehicles. Because the camera of the unmanned aerial vehicle is generally located below the fuselage, there is a blind area above the unmanned aerial vehicle. The target unmanned aerial vehicle flies at a low height and a slow speed to perform its purpose, which greatly improves the capture opportunity. The target unmanned aerial vehicle is found by using equipment and instruments, the distance between the unmanned aerial vehicle and the target unmanned aerial vehicle is zero, and the target unmanned aerial vehicle is quickly dived to approach the target unmanned aerial vehicle by using inertia and flight speed, so that any point of the giant net covers the fuselage of the target unmanned aerial vehicle. The giant net greatly improves the capture probability and reduces the failure probability. The rotation of the propeller of the target unmanned aerial vehicle is forced to stop by winding the giant net, and the target unmanned aerial vehicle falls after losing power. Or the propeller of the target unmanned aerial vehicle does not stop rotating, then the pulling force of the four unmanned aerial vehicles brings the target unmanned aerial vehicle away through the giant net. The technical features of the unmanned aerial vehicle are as follows: a. The four unmanned aerial vehicles are bound as one unmanned aerial vehicle through a program, that is, the same action can be performed simultaneously, or the unmanned aerial vehicles can be dispersed or concentrated, which is similar to the coordinated operation in the unmanned aerial vehicle performance; b. One of the unmanned aerial vehicles is equipped with a high-definition camera, one is equipped with a thermal imaging device, and the other two retain the most basic flight equipment, which can also be equipped with other functions at any time. Such weight reduction can improve flight speed and quickly approach the target unmanned aerial vehicle. The thermal imaging device and the high-definition camera can find the target unmanned aerial vehicle as soon as possible; c. The focus is on flight speed; d. The unmanned aerial vehicles are arranged in a rectangular shape. The technical features of the giant net are as follows: a. The overall area of the giant net should not be too small to miss the target unmanned aerial vehicle, nor too large to affect the flight speed and give the target unmanned aerial vehicle time to escape; b. The mesh should not be too small to increase air resistance and affect flight speed, nor too large to allow the target unmanned aerial vehicle to pass through the mesh or not stop the rotation of the propeller of the target unmanned aerial vehicle or not drag the target unmanned aerial vehicle away; c. The material of the giant net should be low in weight and good in tensile property, and the giant net should be rectangular. The technical features of the combination of the unmanned aerial vehicle and the giant net are as follows: a. The four unmanned aerial vehicles are connected with the four corners of the giant net; b. The unmanned aerial vehicles can carry the giant net to fly at a high speed; c. The unmanned aerial vehicles can be detached from the giant net as needed at the target position; d. The unmanned aerial vehicles can drag the target unmanned aerial vehicle to fly. BRIEF DESCRIPTION OF DRAWINGS: As shown in FIG. 1, '1' giant net is connected with '2' four unmanned aerial vehicles, and '1' giant net is dragged by '2' four unmanned aerial vehicles to rise to the highest flight height and expand to the maximum. The target unmanned aerial vehicle '3' is found by using the tracking technology and identification technology of '2' unmanned aerial vehicles, and '3' target unmanned aerial vehicle is quickly approached by '2' unmanned aerial vehicles with '1' giant net. After approaching, '3' target unmanned aerial vehicle is taken away by '2' unmanned aerial vehicles through '1' giant net connected with '2' unmanned aerial vehicles, or '3' target unmanned aerial vehicle is covered by '1' giant net to lose flight power and fall. Through the two ways, the original route of '3' target unmanned aerial vehicle is deviated. EMBODIMENT
