Description

Technical Field

[0001] This invention relates to the field of drone countermeasures technology, specifically to a fully omnidirectional, freely controllable drone countermeasures terminal based on the BeiDou system. Background Technology

[0002] With the rapid development of drone technology, its applications in civilian fields such as aerial surveying, logistics, and emergency rescue are becoming increasingly widespread. It is also gradually penetrating into special scenarios such as security monitoring and military reconnaissance, greatly improving production efficiency and operational convenience. However, the disorderly flight and illegal use of drones have also brought serious airspace security risks. Unauthorized drones may intrude into sensitive areas such as airport airspace, military control zones, government offices, and large-scale event venues, causing a series of problems such as flight delays, information leaks, and security threats, seriously affecting public safety and social order.

[0003] To address the aforementioned security risks, drone countermeasure technology has emerged, and various countermeasure devices have gradually entered the market. Existing drone countermeasure terminals mostly adopt fixed installation or simple attitude adjustment structures. Their fixing mechanisms are usually only compatible with flat installation surfaces. When facing tilted or complex environments such as mountains, slopes, and irregular walls, it is difficult to achieve stable fixation, and there is a lack of effective attitude correction mechanisms. As a result, the detection and interference components of the countermeasure terminal are prone to attitude deviation due to the tilt of the installation surface, and the detection range is biased to one side, failing to achieve all-round coverage. The Beidou countermeasure terminal for drones, which can achieve all-round free and controllable detection and countermeasure, meets the urgent needs of the current airspace security protection field. Summary of the Invention

[0004] The purpose of this invention is to provide an all-around free and controllable UAV Beidou countermeasure terminal, including a fixing mechanism for fixing the device in various environments, a first adjustment mechanism disposed on the fixing mechanism for handling the tilted fixing surface, a second adjustment mechanism disposed on the first adjustment mechanism for converting altitude and angle, a signal processing carrier disposed on the second adjustment mechanism, and a radar detector and jamming transmitter fixedly disposed on the signal processing carrier.

[0005] As a further aspect of the present invention: the fixing mechanism includes a fixing plate, an anchor plate connected to both sides of the fixing plate, and anchor nails symmetrically arranged on the anchor plate. Two nuts are threaded onto the anchor nails, and the nuts are respectively arranged on both sides of the anchor plate.

[0006] As a further embodiment of the present invention: a plurality of first threaded rods are symmetrically arranged on both sides of the fixing plate, the first threaded rods are rotatably connected to the fixing plate, the end of the first threaded rod away from the fixing plate passes through the anchor plate, the first threaded rod is threadedly connected to the anchor plate, and at least two first threaded rods are arranged on the same side of the fixing plate.

[0007] As a further embodiment of the present invention: the first adjustment mechanism includes a servo motor A fixedly disposed at the bottom of the fixed plate, a rotating cylinder rotatably connected to the top of the fixed plate, a top plate fixedly disposed on both sides of the top of the rotating cylinder, a connecting plate fixedly disposed at the bottom of the top plate and located inside the rotating cylinder, a central shaft rotatably disposed between the two connecting plates, a rotating shaft rotatably fitted around the central shaft, a connecting rod fixedly disposed on the rotating shaft, a guide plate fixedly disposed at the top of the top plate and having a semi-circular cross-section, and a sliding plate slidably disposed along the periphery of the guide plate.

[0008] As a further aspect of the present invention: the rotating shaft and the connecting rod are both located between the two guide plates, and the rotating cylinder has a notch for the connecting rod to rotate.

[0009] As a further aspect of the present invention: a second threaded rod is threadedly connected to the guide plate, one end of the second threaded rod passing through the guide plate and abutting against the side of the rotating shaft.

[0010] As a further aspect of the present invention: the second adjustment mechanism includes a servo motor B fixedly mounted on the sliding plate, a hydraulic cylinder fixedly mounted on the servo motor B, and a hydraulic rod fixedly mounted on the output end of the hydraulic cylinder, wherein the signal processing carrier is fixedly mounted on the top of the hydraulic rod.

[0011] As a further aspect of the present invention: the radar detector captures the BeiDou navigation signals and flight parameters of the UAV in the airspace in real time, and transmits the detection data to the signal processing carrier; the signal processing carrier analyzes the data to determine the UAV's position, speed and flight trajectory, and when an illegally intruding UAV is detected, it outputs a targeted countermeasure command to the jamming transmitter, which then transmits BeiDou navigation and communication frequency band jamming signals to the target UAV to block its navigation and communication links.

[0012] As a further aspect of the present invention: the servo motor A drives the rotating cylinder to rotate, causing the central shaft and the rotating shaft to rotate synchronously. The connecting rod swings with the rotating shaft, pushing the sliding plate to slide along the semi-circular guide plate to complete the attitude correction. After the adjustment is in place, the second threaded rod is tightened so that it abuts against the side of the rotating shaft, locking the position of the rotating shaft, ensuring that the installation plane of the radar detector and the jamming transmitter remains horizontal, and ensuring the directional accuracy of Beidou signal detection and jamming.

[0013] As a further aspect of the present invention: the servo motor B drives the hydraulic cylinder, hydraulic rod and signal processing carrier to rotate continuously, enabling the radar detector to achieve airspace scanning without blind spots and capture UAV Beidou signals from different directions; the hydraulic cylinder drives the hydraulic rod to extend and retract, adjusting the height of the signal processing carrier, expanding the detection range of the radar detector and the countermeasure range of the jamming transmitter, and adapting to complex airspace environments.

[0014] As a further aspect of the present invention: the fixing mechanism, through the cooperation of anchors, nuts and the first threaded rod, enables the device to be stably installed in various environments; the first adjustment mechanism and the second adjustment mechanism work together to correct the installation posture, adjust the height and angle, so that the radar detector and the jamming transmitter always maintain the optimal working posture, continuously receive and transmit Beidou related signals, and ensure the real-time detection and accurate countermeasures of the countermeasure terminal against illegal drones.

[0015] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows: 1.

The present invention provides a stable installation foundation for the overall device through a fixing mechanism. Combined with the first adjustment mechanism for adapting and adjusting the inclined fixing surface, and the second adjustment mechanism for flexibly controlling the height and angle, the signal processing carrier can stably support the radar detector and jamming transmitter, ensuring the accuracy and reliability of the coordinated operation of each component, and effectively improving the efficiency and effect of UAV countermeasures.

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0020] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Please see the appendix Figure 1 - Appendix Figure 5 The present invention provides an all-round free and controllable UAV Beidou countermeasure terminal, including a fixing mechanism 1 for fixing the device in various environments, a first adjustment mechanism 2 set on the fixing mechanism 1, a second adjustment mechanism 3 set on the first adjustment mechanism 2, a signal processing carrier 4 set on the second adjustment mechanism 3, and a radar detector 5 and an jamming transmitter 6 fixedly set on the signal processing carrier 4. Specifically, the terminal achieves functional decomposition and coordination through modular design. The fixed mechanism 1 serves as the load-bearing foundation, directly determining the installation stability of the device in complex environments such as the ground, walls, and platforms. The first adjustment mechanism 2 and the second adjustment mechanism 3 constitute a dual attitude adjustment system. The former specifically corrects the reference deviation caused by the tilt of the fixed surface, while the latter achieves active height and angle adaptation. The two work together to ensure that the radar detector 5 and the jamming transmitter 6 are always in the optimal working attitude. The signal processing carrier 4 serves as the central unit. On the one hand, it receives and analyzes the detection data from the radar detector 5. On the other hand, it outputs countermeasure commands to the jamming transmitter 6, ensuring real-time linkage between detection and countermeasure.

[0022] Furthermore, the fixing mechanism 1 includes a fixing plate 11, an anchoring plate 12 connected to both sides of the fixing plate 11, and anchors 13 symmetrically arranged on the anchoring plate 12. Two nuts 14 are threaded on the anchors 13, and the nuts 14 are respectively arranged on both sides of the anchoring plate 12. Specifically, different types of anchors 13 can be selected according to the installation environment. For example, when installing on the ground, pointed anchors 13 are used to penetrate into the soil, while when installing on walls or platforms, expanded anchors 13 are used to enhance adhesion. The two nuts 14 are respectively attached to the upper and lower or left and right sides of the anchor plate 12. After tightening, they form a bidirectional clamping force, which not only ensures the relative fixation of the anchors 13 and the anchor plate 12, but also compensates for slight unevenness of the installation surface and improves the adaptability of the fixing mechanism 1.

[0023] Furthermore, a number of first threaded rods 15 are symmetrically arranged on both sides of the fixing plate 11. The first threaded rods 15 are rotatably connected to the fixing plate 11. The end of the first threaded rod 15 away from the fixing plate 11 passes through the anchor plate 12. The first threaded rod 15 is threadedly connected to the anchor plate 12. At least two first threaded rods 15 are arranged on the same side of the fixing plate 11. Specifically, at least two first threaded rods 15 are provided on the same side of the fixing plate 11. Their core function is to adjust the distance between the fixing plate 11 and the anchor plate 12, thereby expanding the distribution range of the anchoring points by increasing the lateral span between the two, making the contact between the fixing mechanism 1 and the mounting surface more balanced, and thus significantly improving the installation stability of the overall device. At the same time, when there are unavoidable protrusions on the mounting surface, the gap between the fixing plate 11 and the anchor plate 12 can be widened by adjusting the extension and retraction of the first threaded rods 15, accommodating the protrusions between them and preventing them from affecting the installation fit. The first threaded rods 15 and the fixing plate 11 are rotatably connected, and the bearing cooperation can reduce the mechanical friction during adjustment, making the extension and retraction operation smoother. The threaded connection design with the anchor plate 12 can achieve automatic position locking after the distance is adjusted to the correct position, ensuring that the relative position of the fixing plate 11 and the anchor plate 12 is stable and will not shift due to external forces such as vibration.

[0024] It is worth noting that the first adjustment mechanism 2 includes a servo motor A21 fixedly mounted at the bottom of the fixed plate 11, a rotating cylinder 22 rotatably connected to the top of the fixed plate 11, a top plate 23 fixedly mounted on both sides of the top of the rotating cylinder 22, a connecting plate 24 fixedly mounted at the bottom of the top plate 23 inside the rotating cylinder 22, a central shaft 25 rotatably mounted between the two connecting plates 24, a rotating shaft 26 rotatably mounted around the central shaft 25, a connecting rod 27 fixedly mounted on the rotating shaft 26, a guide plate 28 fixedly mounted on the top of the top plate 23 with a semi-circular cross section, and a sliding plate 29 slidably mounted along the periphery of the guide plate 28. Specifically, after the servo motor A21 starts, it drives the rotating cylinder 22 to rotate around the rotating shaft at the top of the fixed plate 11. The rotational motion of the rotating cylinder 22 is transmitted to the connecting plate 24 through the top plate 23, which in turn drives the central shaft 25 to rotate synchronously. The rotating shaft 26 can rotate freely around the central shaft 25, and its rotation angle is adjusted by the swing of the connecting rod 27. Since the cross-section of the guide plate 28 is semi-circular, the sliding plate 29 can adjust the tilt angle synchronously when sliding along the guide plate 28, so as to realize the posture correction of the second adjustment mechanism 3 and subsequent components carried on the sliding plate 29 and offset the influence of the tilt of the fixed surface.

[0025] It should be noted that the rotating shaft 26 and the connecting rod 27 are both located between the two guide plates 28, and the rotating cylinder 22 has a notch 221 for the connecting rod 27 to rotate; Specifically, the rotating shaft 26 and the connecting rod 27 are located between two guide plates 28, which can prevent lateral deviation and ensure the accuracy of the rotation trajectory. The size of the notch 221 of the rotating cylinder 22 is designed according to the maximum swing amplitude of the connecting rod 27, which not only avoids mechanical interference between the connecting rod 27 and the rotating cylinder 22 when rotating, but also provides sufficient room for the connecting rod 27 to move, so that the angle adjustment range of the first adjustment mechanism 2 covers the correction requirements of common inclined fixed surfaces, and ensures that the plane where the signal processing carrier 4 is located always remains horizontal.

[0026] Furthermore, a second threaded rod 281 is threadedly connected to the guide plate 28, one end of which passes through the guide plate 28 and abuts against the side of the rotating shaft 26. Specifically, the threaded connection between the second threaded rod 281 and the guide plate 28 has a self-locking function, which can automatically maintain the locked state after tightening without the need for an additional locking structure; its end can be equipped with an anti-slip pad or made of rubber to enhance the friction with the side of the rotating shaft 26 and improve the locking reliability; during adjustment, the rotating shaft 26 can be released by loosening the second threaded rod 281, and then tightened after adjustment. The operation is simple and the locking effect is stable, ensuring that the posture adjustment of the first adjustment mechanism 2 is both flexible and reliable.

[0027] Furthermore, the second adjustment mechanism 3 includes a servo motor B31 fixedly mounted on the sliding plate 29, a hydraulic cylinder 32 fixedly mounted on the servo motor B31, and a hydraulic rod 33 fixedly mounted on the output end of the hydraulic cylinder 32. The signal processing carrier 4 is fixedly mounted on the top of the hydraulic rod 33. Specifically, the servo motor B31 drives the hydraulic cylinder 32, hydraulic rod 33, and signal processing carrier 4 to rotate continuously, ensuring that the radar detector 5 can scan the surrounding airspace without blind spots, and that the jamming transmitter 6 can accurately target the UAV. The hydraulic cylinder 32 drives the hydraulic rod 33 to extend and retract through hydraulic transmission, which can adjust the height of the signal processing carrier 4 according to actual needs. This can not only improve the effective range of detection and countermeasures, but also adapt to different installation environments, greatly improving the practicality of the terminal in complex scenarios. The signal processing carrier 4 is fixed on the top of the hydraulic rod 33, and its installation position ensures that the radar detector 5 and the jamming transmitter 6 can receive and transmit signals without obstruction, ensuring work efficiency.

[0028] In this invention, radar detector 5 captures the BeiDou navigation signals and flight parameters of UAVs in the airspace in real time and transmits the detection data to signal processing carrier 4. Signal processing carrier 4 analyzes the data to determine the position, speed and flight trajectory of the UAV. When an illegally intruding UAV is detected, it outputs a targeted countermeasure command to jamming transmitter 6. Jamming transmitter 6 targets the UAV and transmits jamming signals in the BeiDou navigation and communication frequency bands to block its navigation and communication links.

[0029] In this invention, the servo motor A21 drives the rotating cylinder 22 to rotate, which in turn drives the central shaft 25 and the rotating shaft 26 to rotate synchronously. The connecting rod 27 swings with the rotating shaft 26, pushing the sliding plate 29 to slide along the semi-circular guide plate 28 to complete the attitude correction. After the adjustment is in place, the second threaded rod 281 is tightened so that it abuts against the side of the rotating shaft 26, locking the position of the rotating shaft 26 and ensuring that the mounting planes of the radar detector 5 and the jamming transmitter 6 remain horizontal, thus ensuring the directional accuracy of Beidou signal detection and jamming.

[0030] In this invention, the servo motor B31 drives the hydraulic cylinder 32, the hydraulic rod 33 and the signal processing carrier 4 to rotate continuously, enabling the radar detector 5 to achieve airspace scanning without blind spots and capture the BeiDou signals of UAVs in different directions; the hydraulic cylinder 32 drives the hydraulic rod 33 to extend and retract, adjust the height of the signal processing carrier 4, expand the detection range of the radar detector 5 and the countermeasure range of the jamming transmitter 6, and adapt to complex airspace environments.

[0031] In this invention, the fixing mechanism 1 achieves stable installation of the device in various environments through the cooperation of anchor pins 13, nuts 14 and first threaded rods 15; the first adjustment mechanism 2 and the second adjustment mechanism 3 work together to correct the installation posture, adjust the height and angle, so that the radar detector 5 and the jamming transmitter 6 always maintain the optimal working posture, continuously receive and transmit Beidou related signals, and ensure the real-time detection and accurate countermeasure of the countermeasure terminal against illegal drones.

[0032] Working principle: When this all-around freely controllable UAV Beidou countermeasure terminal is in operation, the fixing plate 11 is first placed at the target installation position, and then the anchors 13 on the anchor plate 12 are inserted into the ground or fixed object. The nuts 14 on both sides of the anchors 13 are tightened and locked to make the anchor plate 12 fit tightly with the installation surface, thereby fixing the fixing plate 11. If the installation environment requires fine adjustment of the position of the anchor plate 12, the first threaded rods 15 symmetrically arranged on both sides of the fixing plate 11 can be rotated. Since the first threaded rods 15 are threadedly connected to the anchor plate 12 and rotatably connected to the fixing plate 11, the anchor plate 12 can be pushed or pulled to move during the rotation, ensuring that the fixing mechanism 1 can form a stable foundation in various environments, providing stable support for subsequent adjustment and countermeasure work.

[0033] After fixing, the first adjustment mechanism 2 is activated to address the issue of the tilted fixing surface. The servo motor A21 at the bottom of the fixing plate 11 drives the rotating cylinder 22 at the top to rotate. The top plates 23 on both sides of the top of the rotating cylinder 22 rotate synchronously. The connecting plate 24 at the bottom of the top plate 23, located inside the rotating cylinder 22, drives the central shaft 25 between the two connecting plates 24 to rotate. The rotating shaft 26, which is mounted around the central shaft 25, can rotate freely around the central shaft 25. The notch 221 on the rotating cylinder 22 is not used to restrict the movement area of ​​the connecting rod 27, but rather to increase the range of motion of the connecting rod 27 through an avoidance design, allowing the connecting rod 27 to rotate approximately 180 degrees, avoiding contact with... When structural interference occurs in the rotating cylinder 22, the position of the sliding plate 29, which slides along the periphery of the guide plate 28, can be adjusted by adjusting the rotation angle of the rotating shaft 26. The guide plate 28 has a semi-circular cross section and is fixed to the top of the top plate 23. The rotating shaft 26 and the connecting rod 27 are both located between the two guide plates 28. After the angle is adjusted to be horizontal to the plane where the signal processing carrier 4 is located, the second threaded rod 281 on the guide plate 28 is tightened so that one end of it abuts against the side of the rotating shaft 26, locking the position of the rotating shaft 26, thereby offsetting the influence of the inclined fixed surface and preventing the detection range from deviating to one side when the signal processing carrier 4 rotates.

[0034] Subsequently, the second adjustment mechanism 3 adjusts the height and angle according to the detection requirements. The servo motor B31 on the sliding plate 29 is responsible for controlling the angle rotation in the horizontal direction, driving the hydraulic cylinder 32 and hydraulic rod 33 above to rotate synchronously. The hydraulic cylinder 32 drives the hydraulic rod 33 at the output end to extend and retract, changing the height of the signal processing carrier 4 fixed on the top of the hydraulic rod 33, realizing the free conversion between height and angle, and ensuring that the radar detector 5 and the jamming transmitter 6 can cover a wider detection range.

[0035] The signal processing carrier 4 serves as the core hub, housing the radar detector 5 and the jamming transmitter 6. The radar detector 5 continuously transmits detection signals to capture the BeiDou navigation signals and flight parameters of UAVs in the surrounding airspace. The detection data is transmitted to the signal processing carrier 4 in real time for analysis and processing to determine key information such as the UAV's position, speed, and flight trajectory. When an illegally intruding UAV is detected, the signal processing carrier 4 immediately sends a command to the jamming transmitter 6. The jamming transmitter 6 transmits jamming signals targeting the UAV's BeiDou navigation and communication frequency bands, blocking the communication link between the UAV and the ground control terminal, and simultaneously interfering with its navigation system, causing the UAV to lose control or deviate from its predetermined flight path, ultimately achieving countermeasures against the UAV.
