Description

Reusable intelligent elastic net

The invention belongs to the technical field of anti-unmanned aerial vehicles, and relates to a reusable intelligent missile net.

Background

With the rise and popularity of micro-miniature aircraft, particularly consumer-type multi-rotor drones, represented by aerial photography. Unmanned aerial vehicles play an increasingly important role in civil and military application fields such as aerial photography, catering, logistics, power routing inspection, reconnaissance, attack, special combat and the like.

However, as the unmanned aerial vehicle control technology develops and the industrial technology matures, the use threshold of the unmanned aerial vehicle is also greatly reduced. The unordered use of drones and unauthorized piloting have created an increasing threat to civil airliners, to the society and to the privacy of individuals, and even to public safety.

Because the unmanned aerial vehicle is usually low in manufacturing cost, low in flying height, low in flying speed and small in size, the unmanned aerial vehicle shuttles between urban buildings and is close to public space due to being in a radar blind area, and even if the unmanned aerial vehicle is found, the unmanned aerial vehicle is difficult to counter-act by a conventional method. If the missile is used for destruction, the cost is high, and secondary damage can be caused.

The protection of the low-altitude, slow-speed and micro unmanned aerial vehicles with low cost is one of the important subjects of unmanned aerial vehicle protection.

The method for protecting the low-altitude, slow-speed and micro unmanned aerial vehicle at home and abroad comprises the following steps:

training the hawk, wherein after the special training of the hawk is reported by a Holland police, the hawk can quickly and quickly capture an individual aerial unmanned aerial vehicle; the problem with this method is that training of the hawks takes a certain period of time and the number of hawks is limited. The method is difficult to popularize and apply on a large scale.

Electromagnetic pressing is used, such as the Anti-drone defense system Anti-UAV defenses developed by Liteye corporation. The system can electromagnetically suppress and block the unmanned aerial vehicle from acquiring satellite navigation positioning signals, so that the unmanned aerial vehicle is lost, and the invading unmanned aerial vehicle is forced to land. However, with the development of assisted navigation functionality, more and more drones will reduce or get rid of the dependence on satellite navigation and positioning signals. The field of application of this method is gradually limited. In addition, for some non-cooperative drones, it may not necessarily enter a landing state after losing the satellite navigation signal.

And missile net capture, such as the skywall-100 unmanned plane capture system developed by Liteye. The skywall-100 unmanned aerial vehicle capturing system is used for launching and capturing the missile net through the compressed gas launching device, the missile net flies to a target through an inertia trajectory after being launched, and the missile net releases the capture net to capture the target after approaching the target.

The protection method for the launch capture missile net has the following problems:

a, compressed gas is used for launching and capturing a missile net, the range is limited, and the maximum range is not more than 100 meters;

b, the missile net flies in an inertial trajectory after being launched, and cannot cope with a maneuvering target moving at a high speed;

and c, after the target is captured by the releasing and capturing net of the bullet net, the bullet net falls in a free falling mode, secondary damage is easily caused to ground attachments, and the bullet net is not suitable for being used in densely populated or politically sensitive areas.

In order to solve the problems of non-cooperative low-speed small unmanned aerial vehicles in the conventional missile net capture, the invention discloses a reusable intelligent missile net.

Disclosure of Invention

The invention discloses a reusable intelligent elastic net. The problems in the background art can be effectively solved.

In order to achieve the purpose, the invention adopts the technical scheme that:

the utility model provides a repeatedly usable intelligence bullet net, includes the propeller cap, the screw, motor power, positioning sensor, battery compartment, bullet net cabin, the radome fairing, vision sensor, control and information processing cabin, projectile body frame and bullet arm. The multi-group propeller cap is connected with the propeller, the lower end of the propeller is connected with the power motor, the power motor is connected with one end of the elastic arm, the middle part of the elastic arm is provided with the positioning sensor, the other end of the elastic arm is connected with the elastic body frame, the upper part of the elastic body frame is connected with the control and information processing cabin, the upper part of the control and information processing cabin is connected with the elastic net cabin, the outer part of the elastic net cabin is connected with the fairing, the top end of the fairing is provided with the visual sensor, and the lower end of the elastic body frame is connected with the battery cabin.

Furthermore, in the flight stage, the multiple groups of power motors run at full speed to drive the propellers to generate lifting force which is several times to dozens of times of self gravity, overcome the gravity and provide flight power until the propellers fly to a target area.

Further, when the multiple groups of positioning sensors are close to the target, the motion relation between the target and the intelligent bullet net is detected, and signals are transmitted to the control and information processing cabin.

Furthermore, the control and information processing cabin receives target signals sent by a plurality of groups of positioning sensors to form a guiding instruction, controls a plurality of groups of power motors and adjusts the postures of the intelligent missile net to track the target.

Further, when the intelligent elastic net approaches to the target, the visual sensor captures image information of the target, and the control and information processing cabin identifies the image information of the target captured by the visual sensor.

Further, the control and information processing module performs different processes according to the category of the target captured by the vision sensor. If the target to be captured is determined to be the target to be captured, a capture instruction is sent out; if the target is judged to be a non-capture target, a non-capture instruction is sent out; if the judgment is made by manual judgment, the control and information processing cabin sends out a corresponding instruction to wait for the manual judgment instruction, and if the waiting fails, the control and information processing cabin judges that the acquisition is not performed.

Further, when the intelligent missile net is in a non-capture instruction, the intelligent missile net can cruise according to a preset waypoint or be operated manually.

Further, when the intelligent missile net is in a capture state and accords with a capture distance with a target, the control and information processing cabin outputs a cabin opening capture instruction, and the missile net cabin breaks through the fairing and opens by means of inertia until the target is captured.

Further, when a target is captured, the multiple groups of power motors stop rotating, the rotating speed of the multiple groups of propellers is zero, and the target drives the projectile body to fall.

Furthermore, the attitude sensor in the control and information processing cabin senses a falling signal to switch the working mode of the intelligent missile net, and after the working mode is switched, the intelligent missile net works in an inverted state.

Furthermore, in the inverted flight state, the groups of the spirals of the intelligent missile net rotate in opposite phases to generate lift force, and the control and information processing cabin controls the intelligent missile net in inverted flight to return to the set position.

Compared with the prior art, the invention has the following beneficial effects:

the device is free of a transmitting device, and is convenient to carry, transport, arrange and transmit;

the device has a cruising function and can deal with a long-distance target;

the system has the function of human intervention in a loop, and can cope with complex scenes;

the tracking function is provided, and mobility targets can be dealt with;

the device has a treatment function, and can avoid secondary collateral damage;

the core component can be repeatedly used, and the use cost is low.
