Description

Technical Field

[0001] The present invention relates to the technical field of drone countermeasures, and more specifically, to drone receiving signal countermeasure equipment and a method for sorting the same. Background Art

[0002] Drone signal countermeasure equipment, also known as anti-drone system or drone control equipment, is a high-tech device specially designed to monitor, interfere with or control the flight of drones. In order to adapt to a wider range of control effects and more flexible response capabilities, existing drone control equipment usually uses vehicle-mounted drone countermeasure equipment, which can be quickly deployed and play a role in various complex environments.

[0003] A radar device is usually connected to the top of the vehicle-mounted drone countermeasure equipment to transmit countermeasure signals. However, when the vehicle-mounted equipment is moved as a whole to the target countermeasure location, the radar device is at a higher position and may be tripped or hit by plants or other obstacles in the environment, causing wear and tear on the radar device, resulting in possible erroneous transmission of the countermeasure signal and increased overall usage costs.

[0004] To this end, the present invention provides a drone receiving signal countermeasure device and a sorting method thereof. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] A first aspect of the present invention provides a signal countermeasure device for receiving unmanned aerial vehicles, including a signal countermeasure trolley, the top of which is connected to a storage box assembly, a radar signal assembly is arranged on the inner side of the storage box assembly, and a dust cover is arranged on one side of the storage box assembly. When the dust cover is flipped to the top of the storage box assembly, the radar signal assembly is squeezed into a disc shape and the radar signal assembly is completely stored inside the storage box assembly.

[0007] When the dust cover is attached to the top of the storage box assembly, the storage box assembly forms a storage space to protect the radar signal assembly from being impacted by external plants and other obstacles.

[0008] Furthermore, the storage box assembly includes a box body, a support base is fixedly connected to one side of the box body, a rotating square groove is opened on the top of the support base, a circular shaft is rotatably connected to the inner side of the rotating square groove of the support base, a driving motor is fixedly connected to the back side of the circular shaft of the support base, and the outer side of the circular shaft of the support base is fixedly connected to the dust cover.

[0009] Furthermore, the radar signal component includes an adjustment ring component, which includes a first ring, a second ring, a third ring and a fourth ring. The inner diameters of the first ring, the second ring, the third ring and the fourth ring are proportionally enlarged and diffusely distributed in sequence. The outer circumference of the first ring is fixedly connected to the second connecting seat, the inner circumference of the fourth ring is fixedly connected to the first connecting seat, the inner and outer sides of the second ring are fixedly connected to the first connecting seat and the second connecting seat respectively, and the inner and outer sides of the third ring are fixedly connected to the first connecting seat and the second connecting seat respectively.

[0010] Furthermore, the radar signal component also includes a length adjustment component, and the first ring, the second ring, the third ring, and the fourth ring are movably connected through the length adjustment component. The length adjustment component includes an inner rod, and an outer sleeve is movably provided on the outer side of the bottom of the inner rod, and a spring is fixedly connected to the bottom of the inner wall of the outer sleeve, and the top of the spring is fixedly connected to the bottom of the inner rod.

[0011] Furthermore, the inner sides of the first connecting seat and the second connecting seat are fixedly connected with connecting rods, the inner rod is rotatably clamped on the outer side of the connecting rod of the first connecting seat, the bottom of the outer sleeve is rotatably clamped on the outer side of the connecting rod of the second connecting seat, and both sides of the connecting rod of the first connecting seat are fixedly connected with torsion springs, and one end of the torsion spring close to the inner rod is fixedly connected to the inner rod.

[0012] When the dust cover is detached from the top of the radar signal component, the radar signal component is reset to the radar signal transmitting state and performs signal detection normally.

[0013] Furthermore, an angle adjustment component is connected to the bottom of the radar signal component, and the angle adjustment component includes a base, and elastic columns are fixedly connected on all four sides of the top of the base. A cross arm is provided on one side of the base, and a circular shaft is fixedly connected to one side of the cross arm of the base, and a servo motor is fixedly connected to the front of the circular shaft of the base, and the center of the top of the base is fixedly connected to the bottom of the first ring.

[0014] The angle adjustment component can adjust the angle of the radar signal component to improve the accuracy of the radar signal component during radar detection.

[0015] Furthermore, the front and back sides of the outer side of the circular axis of the base are fixedly connected with pressure plates, the top of the box body is provided with a square groove, the top of the square groove of the box body is fixedly connected with an outgoing air duct and an inner air outlet duct, and the inner air outlet duct is located on the inner side of the outgoing air duct.

[0016] The outgoing air duct and the inner air duct can blow away the dust attached to the surface of the adjusting ring assembly.

[0017] Furthermore, an L-shaped support block for limiting the dust cover is fixedly connected to one side of the outer protective seat.

[0018] The L-shaped support block positions the bottom of the dust cover to improve the stability and stability of the dust cover.

[0019] A second aspect of the present invention provides a method for sorting drone receiving signal countermeasure devices, comprising the following steps:

[0020] S1. Signal detection and reception: The signal countermeasure vehicle control area is divided into multiple control points. When a drone enters the monitoring range of the signal countermeasure vehicle, the signal receiving module begins to fully receive all drone signals detected and transmits the signals to the next unit for analysis.

[0021] S2, signal feature sorting: first assign a unique label to all drone signals, then input the signal parameters into the K-means clustering algorithm to classify similar signals into one category, use a convolutional neural network to process the time-frequency characteristics of the signal parameters to determine the mission objectives of the drone, sort and output the results;

[0022] S3. Countermeasure execution: After sorting and determining the drone signal to be countered, the control system controls the signal countermeasure vehicle to move to the target countermeasure location, and uses the radar signal component to execute countermeasures on the target drone according to the countermeasures determined by sorting.

[0023] The beneficial effects of the present invention are:

[0024] The drone receiving signal countermeasure device and the sorting method thereof described in the present invention cooperate with each other by arranging a storage box assembly, a dust cover plate, and a radar signal assembly. During the process of flipping the dust cover plate to the top of the storage box assembly, the radar signal assembly is squeezed into a disc shape. At this time, the radar signal assembly is in a storage state. When the dust cover plate is attached to the top of the storage box assembly, the storage box assembly forms a storage space. When the signal countermeasure trolley does not reach the target countermeasure location, the control system first stores the radar signal assembly into the storage box assembly to protect the radar signal assembly from being hit by external plants and other obstacles. When arriving at the target countermeasure location, the dust cover plate flips to one side to expose the top of the storage box assembly. The radar signal assembly is reset to the radar signal transmission state under the action of the torsion spring rebound, and signal detection is performed normally.

[0025] The drone receiving signal countermeasure device and the sorting method thereof described in the present invention are configured with an angle adjustment component, which can adjust the angle of the radar signal component. During radar detection, the angle is adjusted to assist the radar signal component in avoiding obstacle signal objects, thereby improving the accuracy of the radar signal component. When recovering the radar signal component, the angle adjustment component can adjust the inclination angle of the radar signal component and the angle between the dust cover and the storage box component when the dust cover is flipped, so that the contact surface of the dust cover is larger when contacting the radar signal component, the extrusion efficiency is higher, and when the angle is reduced, the dust on the surface of the radar signal component is blown away by the outgoing air duct and the inner air outlet duct.

[0026] The drone receiving signal countermeasure device and the sorting method thereof described in the present invention, by setting an L-shaped support block and a dust cover, when a radar signal component is used for radar detection, the dust cover can be provided to the accompanying staff as a temporary operating table, and the L-shaped support block positions the bottom thereof to improve the stability and stability of the dust cover. When the radar signal component is in a storage state, since the L-shaped support block is L-shaped, the L-shaped support block can also be used as a temporary storage rack.

Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0038] like Figures 1 to 8 As shown, the drone receiving signal countermeasure device and the sorting method thereof according to the embodiment of the present invention, please refer to Figure 1 , Figure 2 , including a signal countermeasure trolley 1, the top of the signal countermeasure trolley 1 is connected to a storage box assembly 2, the inner side of the storage box assembly 2 is provided with a radar signal assembly 4, and one side of the storage box assembly 2 is provided with a dust cover 3. When the dust cover 3 is flipped to the top of the storage box assembly 2, the radar signal assembly 4 is squeezed into a disc shape, and the radar signal assembly 4 is completely stored inside the storage box assembly 2.

[0039] Specifically, the storage box assembly 2, the dust cover 3, and the radar signal assembly 4 are arranged to cooperate with each other, and the dust cover 3 is flipped to the top of the storage box assembly 2 to squeeze the radar signal assembly 4 into a disc shape. At this time, the radar signal assembly 4 is in a storage state, and the storage box assembly 2 forms a storage space when the dust cover 3 is attached to the top of the storage box assembly 2. When the signal countermeasure vehicle 1 does not reach the target countermeasure location, the control system first stores the radar signal assembly 4 into the storage box assembly 2 to protect the radar signal assembly 4 from being hit by external plants and other obstacles. When it arrives at the target countermeasure location, the dust cover 3 is flipped to one side to expose the top of the storage box assembly 2, and the radar signal assembly 4 is reset to the radar signal transmission state to perform signal detection normally.

[0041] Specifically, the bottom area of ​​the dust cover 3 is the same as the top area of ​​the box 201. When the driving motor 206 is started to drive the circular shaft of the support seat 205 to rotate, the dust cover 3 will be driven to rotate together until it covers the top of the box 201. A rounded corner is provided on one side of the dust cover 3, and the depth of the rotating square groove of the support seat 205 just matches the rounded corner gap of the dust cover 3, ensuring that the dust cover 3 can rotate normally.

[0042] Please refer to Figure 4 , Figure 5 The radar signal component 4 includes an adjustment ring component 401, which includes a first ring 4011, a second ring 4012, a third ring 4013 and a fourth ring 4014. The inner diameters of the first ring 4011, the second ring 4012, the third ring 4013 and the fourth ring 4014 are proportionally enlarged and diffusely distributed in sequence. The outer circumference of the first ring 4011 is fixedly connected with the second connecting seat 404, the inner circumference of the fourth ring 4014 is fixedly connected with the first connecting seat 403, the inner and outer sides of the second ring 4012 are fixedly connected with the first connecting seat 403 and the second connecting seat 404 respectively, and the inner and outer sides of the third ring 4013 are fixedly connected with the first connecting seat 403 and the second connecting seat 404 respectively.

[0043] Please refer to Figure 4 , Figure 5 The radar signal component 4 also includes a length adjustment component 402, through which the first ring 4011, the second ring 4012, the third ring 4013, and the fourth ring 4014 are movably connected. The length adjustment component 402 includes an inner rod 4021, and an outer sleeve 4022 is movably provided on the outer side of the bottom of the inner rod 4021. The bottom of the inner wall of the outer sleeve 4022 is fixedly connected with a spring 4023, and the top of the spring 4023 is fixedly connected to the bottom of the inner rod 4021.

[0044] Please refer to Figure 4 , Figure 5The inner sides of the first connecting seat 403 and the second connecting seat 404 are fixedly connected with connecting rods, the inner rod 4021 is rotatably clamped on the outer side of the connecting rod of the first connecting seat 403, the bottom of the outer sleeve 4022 is rotatably clamped on the outer side of the connecting rod of the second connecting seat 404, and both sides of the connecting rod of the first connecting seat 403 are fixedly connected with torsion springs 4024, and one end of the torsion spring 4024 close to the inner rod 4021 is fixedly connected to the inner rod 4021.

[0045] Specifically, the initial state of the radar signal component 4 is the radar signal transmitting state, such as Figure 4 As shown, at this time, the inner rod 4021 moves the longest distance relative to the spring 4023, and the torsion spring 4024 is in the initial state. When squeezed by the dust cover 3, the fourth ring 4014 is first squeezed to be flush with the third ring 4013. At this time, the torsion spring 4024 is torsionally deformed as the inner rod 4021 rotates, and then the third ring 4013 and the second ring 4012 are squeezed successively until the first ring 4011, the second ring 4012, the third ring 4013, and the fourth ring 4014 are completely flush to the same height. At this time, the dust cover 3 just covers the top of the storage box assembly 2, and the radar signal assembly 4 is completely stored inside the box body 201 to protect the radar signal assembly 4 from external damage.

[0046] Please refer to Figure 4 , Figure 8 The bottom of the radar signal component 4 is connected to an angle adjustment component 6, and the angle adjustment component 6 includes a base 601. Elastic columns 602 are fixedly connected to the four sides of the top of the base 601. A cross arm is provided on one side of the base 601. A round shaft is fixedly connected to one side of the cross arm of the base 601. A servo motor 603 is fixedly connected to the front of the round shaft of the base 601. The center of the top of the base 601 is fixedly connected to the bottom of the first ring 4011.

[0047] Specifically, mounting seats are provided on the front and back sides of the inner wall of one side of the box body 201, the servo motor 603 is fixedly installed on the mounting seat on the front side, and the base 601 is rotatably connected to the mounting seat on the back side, and the elastic column 602 buffers the bottom of the second ring 4012 during the recovery process to prevent the second ring 4012 from being hit.

[0048] Please refer to Figure 1 , Figure 2 , Figure 8The front and back sides of the outer side of the circular axis of the base 601 are fixedly connected with a pressure plate 604, and a square groove is opened on the top of the box body 201. The top of the square groove of the box body 201 is fixedly connected with an outgoing air duct 202 and an inner air outlet duct 203. The inner air outlet duct 203 is located on the inner side of the outgoing air duct 202. The outgoing air duct 202 and the inner air outlet duct 203 are provided with multiple groups and distributed in an arc shape. The outgoing air duct 202 and the inner air outlet duct 203 are both in an open state, and multiple outgoing air ducts 202 and multiple inner air outlet ducts 203 are connected by an arc-shaped pipe. An elastic pipe is arranged on the side close to the pressure plate 604. The elastic pipe is a hollow structure and is connected to the arc-shaped pipe. The arc-shaped pipe is closed by the elastic pipe on the side close to the pressure plate 604.

[0049] Specifically, when the servo motor 603 drives the base 601 to rotate and adjust the angle with the square groove of the box body 201 to decrease, the pressure plate 604 will rotate accordingly to squeeze the elastic pipe, causing the gas circulating in the arc-shaped pipe to be squeezed and discharged through the openings of the outgoing air duct 202 and the inner air outlet duct 203 to blow away the dust attached to the surface of the adjustment ring assembly 401; when the servo motor 603 drives the base 601 to rotate and adjust the angle with the square groove of the box body 201 to increase, the elastic pipe automatically resets, and under the action of atmospheric pressure, the inside of the arc-shaped pipe is filled again, so that the dust blowing operation can be performed the next time the pressure plate 604 squeezes the elastic pipe.

[0050] Please refer to Figure 3 , Figure 7 An L-shaped support block 5 for limiting the dust cover plate 3 is fixedly connected to one side of the outer protective seat 204 .

[0051] Specifically, the dust cover 3 can be provided to accompanying staff as a temporary operating table, and the L-shaped support block 5 can improve the stability and stability of the dust cover 3 by positioning its bottom. When the radar signal component 4 is in the storage state, since the L-shaped support block 5 is L-shaped, the L-shaped support block 5 can also be used as a temporary storage rack.

[0052] The method for sorting the drone receiving signal countermeasure device is applied to the drone receiving signal countermeasure device as described above, and comprises the following steps:

[0053] S1, signal detection and reception: The control area of ​​the signal countermeasure vehicle 1 is divided into multiple control points. When the drone enters the monitoring range of the signal countermeasure vehicle 1, the signal receiving module begins to fully receive all drone signals detected and transmits the signals to the next unit for analysis;

[0054] S2, signal feature sorting: first assign a unique label to all drone signals, then input the signal parameters into the K-means clustering algorithm to classify similar signals into one category, use a convolutional neural network to process the time-frequency characteristics of the signal parameters to determine the mission objectives of the drone, sort and output the results;

[0055] S3, countermeasure execution: After sorting and determining the drone signal to be countered, the control system controls the signal countermeasure vehicle 1 to move to the target countermeasure location, and uses the radar signal component 4 to execute countermeasures on the target drone according to the countermeasures determined by sorting.

[0056] How it works

[0057] The initial state of the radar signal component 4 is the radar signal transmitting state, such as Figure 4 As shown, at this time, the inner rod 4021 moves the longest distance relative to the spring 4023, and the torsion spring 4024 is in the initial state. In this state, the servo motor 603 is started to drive the cross arm of the base 601 to rotate and adjust the angle of the base 601, thereby adjusting the angle of the radar signal component 4;

[0058] When the signal countermeasure trolley 1 moves but does not move to the countermeasure point, the radar signal component 4 is stored, and the driving motor 206 is started to drive the round shaft of the support seat 205 to rotate, thereby driving the dust cover 3 to rotate. When the dust cover 3 is about to contact the radar signal component 4, the angle adjustment component 6 can adjust the inclination angle of the radar signal component 4 and the angle between the dust cover 3 and the storage box component 2 when it is turned over, so that the contact surface of the dust cover 3 is larger when it contacts the radar signal component 4. When the radar signal component 4 is squeezed by the dust cover 3, The fourth ring 4014 is first squeezed to be flush with the third ring 4013. At this time, the torsion spring 4024 is torsionally deformed as the inner rod 4021 rotates, and then the third ring 4013 and the second ring 4012 are squeezed successively until the first ring 4011, the second ring 4012, the third ring 4013, and the fourth ring 4014 are completely flush to the same height. At this time, the dust cover 3 just covers the top of the storage box assembly 2, and the radar signal assembly 4 is completely stored inside the box body 201 to protect the radar signal assembly 4 from external damage.

[0059] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
