[0002] With the rapid development of drone technology, drones have been widely used in many fields such as aerial photography, logistics distribution, and agricultural plant protection. However, the disorderly flight of drones has also brought a series of safety hazards, such as interfering with the normal takeoff and landing of civil airliners, infringing on the privacy of others, and threatening the safety of important places. In order to effectively monitor the flight activities of drones, it is necessary to accurately detect drone signals.

This system includes an anti-drone equipment testing system comprising a test control device, a signal generator, a spectrum detection device, and an anti-drone device. The test control device is connected to the signal generator, the spectrum detection device, and the anti-drone device, respectively. Specifically, the test control device is configured to send a drone simulation instruction to the signal generator; the signal generator is configured to simulate and transmit a drone signal corresponding to the drone simulation instruction; the test control device is further configured to send a drone detection and countermeasure instruction to the anti-drone device; the anti-drone device is configured to detect drone signals and transmit drone countermeasure signals in response to the drone signals; the spectrum detection device is configured to detect drone signals and drone countermeasure signals; and the test control device is further configured to determine the detection and countermeasure performance indicators of the anti-drone device. This technical solution can simplify the anti-drone equipment testing process and save time.

[0004] In the existing technology, there are many shortcomings in the existing drone signal detection methods. On the one hand, traditional detection equipment can only operate in a single frequency band and cannot cover the multiple frequency bands commonly used by drones, resulting in limited detection capabilities of drones with signals in different frequency bands. In addition, during the detection process, since it relies on a vehicle as a carrier, but as the vehicle moves, there is a lack of an effective leveling structure, which can easily cause the detection device to shake violently during the detection process, affecting normal use.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention. Example

[0022] See also Figures 1-8 As shown, the present invention provides a technical solution: a multi-band drone signal intelligent detection device, comprising a luggage rack 1 for installation on the top of a vehicle, a connecting mechanism 2 for movement installed on the top of the luggage rack 1, and a supporting mechanism 3 fixedly connected to the inner side of the connecting mechanism 2; A carrying plate 4 is installed inside the support mechanism 3, and an antenna unit 5 is fixedly connected to the top surface of the carrying plate 4. There are two antenna units 5, and the two antenna units 5 are fixedly connected to the left and right sides of the top surface of the carrying plate 4 in opposite directions, and a horizontal module 501 is fixedly connected to the center position of the top surface of the carrying plate 4. A wireless transceiver module 5011 is fixedly connected to the top surface of the carrying plate 4, and a processor 5012 connected to the wireless transceiver module 5011 is also fixedly connected to the top surface of the carrying plate 4. A through hole is provided inside the carrying plate 4, and a radar component 4015 is rotatably connected to the inside of the through hole through a guide shaft 4014. There are two radar components 4015, and the two radar components 4015 are installed in opposite directions on the left and right sides of the top of the carrying plate 4. There are two luggage racks 1, and the two luggage racks 1 are arranged in parallel. Mounting holes 101 are provided on the left and right sides of the inside of the two luggage racks 1, and are fixed to the vehicle body by passing bolts. A longitudinal groove is provided inside the connecting mechanism 2.

[0023] In this embodiment, when using and installing the detection device, first, two parallel luggage racks 1 are passed through the mounting holes 101 and tightly fixed to the top of the vehicle with matching bolts. This step is the basis for the stable operation of the entire device, ensuring that the luggage racks 1 are firmly connected to the vehicle to prevent loosening during driving. After the luggage racks 1 are installed, the connecting mechanism 2 is installed on the top of the luggage racks 1. The two are firmly connected through a specific connecting structure. Then, the supporting mechanism 3 is fixed to the inner side of the connecting mechanism 2. At this point, the basic structure of the device is complete. The horizontal module 501 on the top surface of the carrier plate 4 installed inside the support mechanism 3 immediately starts working. The horizontal module 501 can monitor the horizontal state of the carrier plate 4 in real time. Once the carrier plate 4 tilts, the horizontal module 501 will quickly capture this change and transmit the signal to the processor 5012. At the same time, the antenna unit 5, wireless transceiver module 5011 and processor 5012 on the top surface of the carrier plate 4 are also powered on and enter the ready state. The antenna unit 5 is responsible for receiving drone signals, the wireless transceiver module 5011 is used for signal transmission, and the processor 5012 is responsible for data processing and command sending. The two radar components 4015 rotatably connected inside the carrier plate 4 are also in the initial standby state at this time, ready to perform detection tasks at any time; When the vehicle starts and moves, the carrier plate 4 may tilt due to the shaking of the vehicle. At this time, the horizontal module 501 continuously monitors the horizontality of the carrier plate 4. Once a tilt is detected, the horizontal module 501 will immediately transmit a signal to the processor 5012. After receiving the signal, the processor 5012 calculates the internal preset program and sends an instruction to the relevant adjustment components of the support mechanism 3. After receiving the instruction, the expansion push rod 3011 in the guide frame assembly 301 in the support mechanism 3 will extend or retract according to the tilt of the carrier plate 4. The action of the expansion push rod 3011 drives the moving component 3012 to move in the guide frame assembly 301. The inner side slides up and down, and the second motor 3013 installed on the moving component 3012 is started. The second motor 3013 drives the first gimbal 3014 to rotate. When the first gimbal 3014 rotates, the rotating shaft component 3015 inside it will drive the second gimbal 3016 to adjust the angle accordingly. At the same time, the third motor 3017 on the outside of the first gimbal 3014 also starts to work, accurately controlling the rotation angle of the second gimbal 3016, thereby realizing the horizontal adjustment of the carrying plate 4, ensuring that the antenna unit 5, radar component 4015 and other detection components can be in a stable working posture, and prepare for detecting drone signals. Example

[0024] like Figure 1-Figure 5 As shown, the inner rotation of the longitudinal groove opened in the connecting mechanism 2 is connected with the adjusting rod 201, and the adjusting rod 201 is a screw rod structure. The inner sliding connection of the longitudinal groove opened in the connecting mechanism 2 is an L-shaped expansion frame 2011. The interior of the expansion frame 2011 is provided with a screw hole matching the adjusting rod 201. The outer side of the expansion frame 2011 is fixedly connected with a sliding block 2012. The outer side of each expansion frame 2011 is fixedly connected with two sliding blocks 2012 with raised structures in opposite directions. The expansion frame 2011 is slidably connected to the longitudinal groove opened in the connecting mechanism 2 through the sliding block 2012. The connecting mechanism 2 and the adjusting rod 201 together constitute an up and down driving structure for the expansion frame 2011. The top surface of the connecting mechanism 2 is fixedly connected with a bracket assembly 2013. The bracket assembly A brake push rod 2014 is fixedly connected to the bottom end surface of the transverse member in component 2013. The brake push rod 2014 is longitudinally arranged, and a circular brake block 2015 is fixedly connected to the bottom output shaft of the brake push rod 2014. The bottom end surface of the connecting mechanism 2 and the top surface of the expansion frame 2011 are fixedly connected with side plate assemblies 2016. Every two longitudinally adjacent side plate assemblies 2016 form a group, and the inner side of each group of side plate assemblies 2016 is rotatably connected to a moving wheel 2017. The outer side of a group of side plate assemblies 2016 located on the lower side is fixedly connected to a first motor 2018. The output shaft of the first motor 2018 is connected to the moving wheel 2017 and is used to drive the moving wheel 2017 to rotate. The brake block 2015 is used to limit the rotation of the moving wheel 2017 located on the upper side.

[0025] In this embodiment, when in use, the adjusting rod 201 connected to the longitudinal groove inside the connecting mechanism 2 rotates and starts to rotate under manual drive. The adjusting rod 201 is a screw rod structure, and a screw hole matching it is opened inside the expansion frame 2011. When the adjusting rod 201 rotates, according to the transmission principle of the screw rod nut, the expansion frame 2011 will move up and down along the longitudinal groove of the connecting mechanism 2. The sliding block 2012 fixedly connected to the outside of the expansion frame 2011 plays a key role in the movement of the expansion frame 211. The sliding block 2012 is closely matched with the longitudinal groove of the connecting mechanism 2 to ensure that the expansion frame 211 slides smoothly and prevents it from deflecting or shaking during the movement. Through this adjustment method, the height of the expansion frame 211 can be flexibly adjusted according to actual use needs to adapt to different vehicle types or usage scenarios. The side plate assemblies 2016 are fixedly connected to the bottom end surface of the connecting mechanism 2 and the top surface of the expansion frame 2011. Every two longitudinally adjacent side plate assemblies 2016 form a group, and each group is rotatably connected to the inner side of the moving wheel 2017. When the first motor 2018 fixedly connected to the outer side of a group of side plate assemblies 2016 on the lower side is started, the output shaft of the first motor 2018 drives the moving wheel 2017 to rotate, thereby realizing the movement of the connecting mechanism 2 and the entire device. When it is necessary to stop moving, the bracket assembly 2013 fixedly connected to the top surface of the connecting mechanism 2 comes into play, and the brake push rod 2014 fixedly connected to the bottom end surface of the transverse member in the bracket assembly 2013 is started. The bottom end output shaft of the brake push rod 2014 pushes the brake block 2015 of the circular structure to move downward, and the brake block 2015 contacts and presses the moving wheel 2017 on the upper side, and uses friction to stop the moving wheel 2017 from rotating, thereby realizing the braking of the device, which is convenient for the installation and debugging of the device in different environments. Example

[0026] like Figure 4-Figure 8As shown, every two laterally adjacent connecting mechanisms 2 form a group, and the inner sides of the two groups of connecting mechanisms 2 are fixedly connected with two cylindrical connecting rods 2019 in a linear array, and the inner sides of the connecting rods 2019 are fixedly connected with a supporting mechanism 3, the main body of the supporting mechanism 3 is an L-shaped structure, and the top surface of the transverse member in the supporting mechanism 3 is fixedly connected with a guide frame assembly 301, the interior of the guide frame assembly 301 is provided with a longitudinal groove, the interior of the longitudinal groove is fixedly connected with a longitudinally arranged expansion push rod 3011, the top surface of the expansion push rod 3011 is fixedly connected with a moving assembly 3012, the moving assembly 3012 is slidably connected to the inner position of the guide frame assembly 301, and there are two moving assemblies 3012, the front end of the moving assembly 3012 on the front side is installed with a second motor 3013, and the rear output shaft of the second motor 3013 is installed with a first balancing frame 3014 with an annular structure, and the first balancing frame 301 4 is connected to the inner side of two rotating shaft assemblies 3015 for counter-rotation. The inner sides of the two rotating shaft assemblies 3015 are fixedly connected to a second gimbal 3016 with an annular structure. The outer side of the first gimbal 3014 is fixedly connected to a third motor 3017. The third motor 3017 is used to drive the second gimbal 3016 to rotate. The inner side of the second gimbal 3016 is fixedly connected to a connecting plate 3018 with an annular structure. A connecting hole 3019 is defined within the connecting plate 3018. The carrier plate 4 is mounted on the connecting plate 3018 via a fixing bolt 401. The bottom ends of the two radar assemblies 4015 are coaxially mounted with a guide gear 4013. The two guide gears 4013 are meshed with each other for transmission. A support frame 4011 is also fixedly connected to the bottom end surface of the carrier plate 4. A fourth motor 4012 is mounted on the bottom end of the support frame 4011. The output shaft of the fourth motor 4012 is connected to the guide gear 4013 on the right side.

[0027] In this embodiment, when the vehicle is in use and shakes due to road bumps or turning during driving, the support mechanism 3 will immediately activate the leveling mechanism. Inside the guide frame assembly 301 on the top surface of the cross member of the support mechanism 3, the telescopic rod of the deployment push rod 3011 begins to move linearly. One end of the deployment push rod 3011 is connected to the moving assembly 3012 by a hinge, and the other end is fixed in the longitudinal groove of the guide frame assembly 301. When the push rod is extended or retracted, the moving assembly 3012 is forced to slide linearly along the guide rail of the guide frame assembly 301. The cross-section of the guide rail is dovetail-shaped, which can effectively prevent the moving assembly 3012 from lateral deviation during the sliding process. After the second motor 3013 at the front end of the front moving assembly 3012 is started, its output shaft is rigidly connected to the rotating shaft of the first balancing frame 3014 via a coupling. The rotational motion of the second motor 3013 is directly transmitted to the first balancing frame 3014, causing it to perform circular motion around its rotating axis. A rotating shaft assembly 3015 is provided on each side of the first balancing frame 3014. The rotating shaft assembly 3015 utilizes a deep groove ball bearing structure. The inner ring of the rotating shaft assembly 3015 is interference fit with the rotating shaft of the second balancing frame 3016, and the outer ring is fixed in the bearing seat of the first balancing frame 3014. This structural design enables the second balancing frame 3016 to perform independent rotational motion relative to the first balancing frame 3014. After the third motor 3017 outside the first balancing frame 3014 is started, it drives the rotation of the second balancing frame 3016 through a synchronous belt transmission system. The synchronous belt transmission system consists of a driving pulley, a driven pulley, and a synchronous belt. The driving pulley is mounted on the output shaft of the third motor 3017, and the driven pulley is fixed coaxially with the rotation axis of the second balancing frame 3016. When the third motor 3017 rotates, the power is transmitted to the driven pulley through the meshing action of the synchronous belt, thereby driving the second balancing frame 3016 to rotate precisely. The connecting plate 3018 inside the second balancing frame 3016 is connected to the carrier plate 4 via a fixing bolt 401. The fixing bolt 401 is a high-strength bolt. Its threaded portion tightly fits the screw hole of the connecting plate 3018. The head is locked with a washer and nut to ensure that there is no relative movement between the carrier plate 4 and the connecting plate 3018. When the first balancing frame 3014 and the second balancing frame 3016 work together, the carrier plate 4 can be adjusted in multiple dimensions, effectively offsetting the impact of vehicle shaking on the detection equipment. When the detection range needs to be expanded, the fourth motor 4012 at the bottom of the carrier plate 4 is started. The output shaft of the fourth motor 4012 is connected to the hub of the right guide gear 4013 via a flat key, transmitting torque to the guide gear 4013. The right guide gear 4013 and the left guide gear 4013 mesh with each other. The two gears have the same module and pressure angle, and the gear ratio is 1:1, ensuring that the two gears can achieve constant speed and opposite rotation. The hub of each guide gear 4013 is connected to the rotating shaft of the radar assembly 4015 via a spline, so that the rotational motion of the guide gear 4013 can be directly transmitted to the radar assembly 4015. The rotating shaft of the radar assembly 4015 is supported in a bearing seat on the top of the carrier plate 4. The bearing seat uses a double-row angular contact ball bearing, which can withstand both radial and axial forces, ensuring the stability of the rotation of the radar assembly 4015. To ensure smooth rotation of the radar assembly 4015, a guide mechanism is provided on top of the carrier plate 4. The guide mechanism consists of an annular guide rail fixed to the carrier plate 4 and a slider mounted on the bottom of the radar assembly 4015. A rolling friction pair is used between the slider and the annular guide rail, which can significantly reduce rotational resistance. When the radar assembly 4015 rotates with the guide gear 4013, the slider moves in a circular motion along the annular guide rail, providing additional support and guidance for the radar assembly 4015. During the rotation of radar component 4015, its internal signal processing unit continuously receives and analyzes reflected signals. The signal processing unit uses digital beamforming technology to form a directional beam by weighted synthesis of signals from multiple receiving channels. When radar component 4015 rotates, these beams can cover the surrounding 360° space to achieve all-round detection. At the same time, the signal processing unit also uses Doppler frequency shift detection technology, which can effectively distinguish between drone signals and background clutter, further improving the accuracy of detection.
