Description

Low-slow small target safety interception device
Technical Field
The invention relates to a low-speed small target safety interception device, which mainly relates to the technologies of automatic control, machinery and the like.
Background
The low-slow small target refers to a low-altitude, slow and small aircraft, including rotor unmanned aerial vehicles, fixed-wing unmanned aerial vehicles, balloons and other aircrafts, which have low flying altitude, small volume and low cost and are widely popularized and used in the world, but the aircrafts also pose great threats to the safety management of the airspace. At present, the common intercepting methods for low-speed small targets include firepower interception, laser attack, radio interception, radio interference, unmanned aerial vehicle countermeasure, an intercepting network and the like. Firepower interception is to use weapons such as rocket projectiles and light guided missiles to strike small low-speed targets, but weapon ammunitions have great destructiveness, and ammunition and aircraft fragments are easy to damage ground personnel and facilities, so that the firepower interception can be used only in open and unmanned areas; the laser striking is to burn the parts of the unmanned aerial vehicle by adopting a laser weapon so as to lead the unmanned aerial vehicle to fall; the radio interception is to control the unmanned aerial vehicle to land by adopting the same flight control signal as the unmanned aerial vehicle on the basis of radio interference, and the method is only suitable for part of specific unmanned aerial vehicles with known models; the radio interference is to make the unmanned aerial vehicle lose control of falling by interfering and suppressing radio flight control signals of the aircraft, and the method is only suitable for the aircraft using radio flight control and cannot intercept the aircraft with autonomous navigation function; the unmanned aerial vehicle countermeasure is that the unmanned aerial vehicle with larger volume directly intercepts or impacts the target aircraft in a self-injurious way, and the unmanned aerial vehicle for countermeasure and the target aircraft are crashed on the ground after interception; the interception net can make the aircraft lose the flight ability by throwing the interception net. Except that the radio interception can control the soft landing of the unmanned aerial vehicle, the existing other interception methods can not control the falling process and the falling place of the intercepted aircraft, and the aircraft is easy to cause the explosion of a power system and secondary disasters due to the strong collision with the ground when crashed, thereby causing serious threats to the safety of ground personnel and facilities. In order to solve the problem, part of the intercepting nets are additionally provided with parachutes, but the parachute opening speed is low, the parachute is not opened yet and the aircraft falls down to the ground, and the reliability is poor. Therefore, a new intercepting method and device capable of effectively preventing low-speed small targets from intercepting secondary disasters are needed.
