Description

The invention relates to the field of aviation, in particular to devices for capturing unmanned aerial vehicles.

Known device for combating remotely piloted (unmanned) aircraft (hereinafter referred to as RPV) [Patent RU No. 72754 U1. - IPC: F41H 13/00, publ. 04/27/2008], containing a delivery unit, direction finding unit, guidance unit, container with a trap net, to the edges of which cargoes are attached, where the trap net with weights placed in the container is delivered to the area where the UAV is located using the delivery unit ( missiles), is aimed at the RPV using the guidance unit according to the direction finding unit data obtained by the sound-thermal method, after which the trap net is fired synchronously with four cartridges towards the target, while the sinkers, which are round with holes for fastening keeper tapes, stretch this net -trap, providing cover and capture of the RPV.

The disadvantage of this device is the low probability of capturing true targets, since it is not possible to distinguish between targets during their group attack according to the given criteria for true and false ones, followed by prioritizing capture, taking into account the height, speed and flight trajectory.

Known device for capturing unmanned aerial vehicles [Patent RU No. 2660999 C1. - IPC: В64С 39/02, B64D 5/00, B64D 1/00, publ. 11.07.2018 Bul. No. 20], containing a UAV, an onboard processor, nets with weights, all-round cameras, a shooting device made in the form of a cannon, in which at least two capsules with a net, weights and a parachute are placed, and a movement mechanism is installed on the UAV body responsible for movement guns along the trajectory of the cross-section of the fuselage surface, and a rotation mechanism is installed on the movement mechanism that controls the movement of the gun in the horizontal and vertical planes around the axis, and also on the UAV there are sensors operating in the acoustic range, and sensors operating in three or more tunable radar ranges electromagnetic waves, as well as in the sinkers of the network, sensors for determining the coordinates are mounted.

The disadvantage of this device is the low probability of capturing true targets, due to the inability to distinguish between targets during their group attack according to specified criteria for true and false, followed by prioritization of capture.

The technical result of the proposed method for capturing unmanned aerial vehicles is to increase the likelihood of capturing true targets (enemy UAVs), based on the selection of moving targets, followed by prioritizing their capture according to specified criteria.

The specified technical result is achieved by the fact that the invention includes a UAV, on which an on-board computer complex is installed, optical-electronic cameras of a circular view and a guidance mechanism, on which a shooting device with capsules containing a parachute and a network with weights is installed, while the UAV additionally a control unit is installed in series with the on-board computer complex and a selection unit and a priority unit are installed, the output of which is connected to the first input of the on-board computer complex, and the second output of the control unit is connected to optical-electronic cameras of a circular view, the output of which is connected to the second input of the on-board computer complex , while the third output of the control unit is connected to the combined input of the guidance mechanism and the firing device.

The essence of this invention lies in the fact that a control unit is additionally installed on the UAV, which is connected in series with the on-board computer complex and a selection unit and a priority unit are installed, the output of which is connected to the first input of the on-board computer complex, and the second output of the control unit is connected to the optical-electronic cameras of the circular review, the output of which is connected to the second input of the onboard computer complex, while the third output of the control unit is connected to the combined input of the guidance mechanism and the firing device.

An increase in the probability of capturing true targets of an enemy UAV is provided as follows.

At the moment of detection of enemy UAVs, the number of enemy UAVs and their spatial coordinates are determined using optical-electronic all-round cameras. Further, the obtained data (the spatial coordinates of the enemy UAV and their number) are transmitted to the onboard computer complex, which calculates the height and corrects the data, in particular the spatial coordinates, for example, using the algorithm [Abramovskaya M.V. Development of an algorithm for determining the coordinates of an object for a given direction of the line of sight // Bulletin of the Novgorod State University. No. 4 (95). 2016. P.7-9], their speed and flight trajectory, for example, using the algorithm [Yakovlev KS, Makarov DA, Baskin Ye.S. The method of automatic planning of the trajectory of an unmanned aerial vehicle in conditions of restrictions on the dynamics of the flight // "Modeling and Control". Artificial intelligence and decision making. No. 4. 2014. S. 3-17].

Then the on-board computer complex transmits a signal to the control unit, which issues a command to operate the selection unit. After the command received, the selection unit analyzes the enemy's moving UAVs in order to determine true and false targets according to a given algorithm. Selective analysis can be carried out, for example, through the use of normalized readings of the spectral power density of the reflected signals at different polarizations [Borzov AB, Likhodeenko KP, Muratov IV, Pavlov GL, Suchkov V.B. Analysis of selective signs of ground-based radar targets].

Then the generated data from the selection block is transferred to the capture priority block. The capture priority block determines the most rational and priority target for capture according to the specified evaluation criteria, taking into account the given data from the selection block. After making a criterion assessment, the capture priority block transmits the generated data on the priority capture target to the onboard computer complex, which in turn issues a capture command.

This achieves the technical result specified in the invention.

Figure 1 shows a block diagram that displays the algorithm of the UAV capture device. Figure 2 shows a sketch of the moment of capture of an enemy UAV.

FIG. 1 and 2 are designated: 1 - onboard computer complex, 2 - control unit, 3 - optical-electronic all-round cameras, 4 - selection unit, 5 - capture priority unit, 6 - guidance mechanism, 7 - shooting device, 8 - UAV; 9 - enemy UAV, 10 - net, 11 - sinkers, 12 - capsule, 13 - parachute.

The purpose of control unit 2 is to control such elements of the device as optoelectronic all-round cameras 3, selection unit 4 and targeting mechanism 6 with firing device 7. Control unit 2 can be made as a flight controller based on Arduino.

The purpose of the selection block 4 is to analyze the enemy's UAV 9 in order to determine the true and false targets according to a given algorithm. Selection unit 4 can be made as a device for selecting signals of moving targets.

Capture priority block 5 is designed to determine the highest priority target for capturing enemy UAVs 9. For example, it is possible to make a criterion assessment according to the overall parameters of enemy UAVs 9. Priority block 5 can be performed as a microprocessor with a given calculation algorithm [Zolotukhin S.I., Dyakov D.E., Zibrov R.S., Kotlyarov P.S. The accuracy of calculations when using the method of choosing a rational decision // Journal "Modern high technology". 2019. No. 10. Part 2. P.252-256].

The unmanned aerial vehicle capture device works as follows.

When the enemy UAV 9 enters the coverage area of the optoelectronic all-round cameras 3, a signal is sent about the detection of the enemy UAV 9 to the on-board computer complex 1. Then the on-board computer complex 1 transmits a signal to the control unit 2, which in turn issues a command to the optical- electronic all-round cameras 3 to determine the number of enemy UAVs 9 and their spatial coordinates. Further, the data obtained from the optical-electronic cameras of the circular view 3 (the spatial coordinates of the enemy UAV and their number) are transmitted to the on-board computer complex 1, which calculates the altitude with the correction of data on the spatial coordinates, speed and flight trajectory of the enemy UAV 9.

Then the on-board computer complex 1 transmits a signal to the control unit 2, which commands the operation of the selection unit 4. After the command received, the selection unit 4 makes a distinction between the enemy UAVs 9 during their group attack according to a given algorithm on true and false targets. Further, the generated data from the selection block 4 is transmitted to the capture priority block 5. The capture priority block 5 determines the most rational and priority target for capturing according to the specified evaluation criteria, taking into account the information received from the selection block 4. After making a criterion assessment, the capture priority block 5 transmits the generated data on the priority target of capture to the onboard computer complex 1.

On-board computer complex 1, based on the data received from the capture priority unit 5, issues a command not to the control unit 2 to capture the enemy UAV 9. Further, the control unit 2 issues a signal to work on the guidance mechanism 6, which sets the shooting device 7 at the desired angle in necessary direction for the capture. After that, the control unit 2 issues a command to the shooting device 7 to fire a capsule 12 at the enemy UAV 9. At the moment of passing the given path to the enemy UAV 9, the capsule 12 opens and a net 10 with weights 11 and a parachute 13 flies out of it, through which the capture is carried out Enemy UAV 9 and its subsequent landing.

Then a re-analysis of the air situation is performed, taking into account whether there was a miss or not. Then a decision is made to capture the target. In the case of a miss, the sequence of actions for grabbing is the same.
