Description

Technical Field

[0001] This specification relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a UAV detection device. Background Technology

[0002] With the rapid popularization of drone technology, various countries have successively introduced Remote ID (RID) regulations, requiring drones to broadcast key information such as identification, geographical location, and flight status in real time during flight to ensure airspace safety and regulatory efficiency. However, RID signal transmission relies on wireless communication technologies such as Wi-Fi, Bluetooth, LoRa, or cellular networks. In complex urban electromagnetic environments, high-interference areas around airports, or densely populated industrial areas, RID signals are susceptible to multipath effects, co-channel interference, and other factors. This leads to problems such as signal interruption, increased decoding error rates, and confusion in multi-target identification in some related RID receiving schemes, seriously affecting the real-time response capability and stability of the regulatory system.

[0035] With the rapid popularization of drone technology, various countries have successively introduced Remote ID (RID) regulations, requiring drones to broadcast key information such as identification, geographical location, and flight status in real time during flight to ensure airspace safety and regulatory efficiency. However, the transmission of RID signals relies on wireless communication technologies such as Wi-Fi, Bluetooth, LoRa, or cellular networks. In complex urban electromagnetic environments, high-interference areas around airports, or densely populated industrial areas, RID signals are susceptible to multipath effects, co-channel interference, and other factors. This leads to problems such as signal interruption, increased decoding error rate, and multi-target identification confusion in some related implementations of RID receiving schemes, seriously affecting the real-time response capability and stability of the regulatory system.

[0036] In some related embodiments, drone detection equipment may employ a single-antenna receiving scheme or simple diversity reception technology. However, single-antenna receiving schemes or simple diversity reception technologies are difficult to be compatible with RID standards of different countries / regions (such as ASTM F3411 in the United States and SC-01 in the European Union), and are prone to signal aliasing when multiple drones broadcast simultaneously. In some related use cases, the compact antenna layout resulting from the miniaturized design of drone detection equipment can easily lead to electromagnetic coupling, reducing receiver sensitivity. Some related anti-interference schemes (such as narrowband filtering or static beamforming) are difficult to adapt to dynamically changing wireless environments, resulting in a sharp decline in performance in complex scenarios.

[0037] Based on this, one or more embodiments of this specification provide a drone detection device, which includes a reflective surface capable of reflecting RID signals below a certain position. It is suitable for complex urban electromagnetic environments, high-interference areas around airports, or densely populated industrial areas, and has a high target drone RID signal capture rate, strong anti-interference capability, and multi-environment adaptability.

[0038] Figure 1 , Figure 2 These are schematic diagrams of unmanned aerial vehicle (UAV) detection equipment shown in some embodiments of this specification. Figure 3This is a schematic diagram of the bottom of a drone detection device according to some embodiments shown in this specification. Figure 8 This is an exploded view of a drone detection device according to some embodiments of this specification. See also Figures 1 to 3 as well as Figure 8 As shown, in one or more embodiments of this specification, the drone detection device may include: a housing 1, a plate-like structure 2 disposed within the housing 1, and a first antenna 3. In some embodiments, the housing 1 includes a bottom surface 11 and a side wall 12 surrounding the bottom surface 11, and the plate-like structure 2 is located between the upper ends of the bottom surface 11 and the side wall 12. In some embodiments, the first antenna 3 is disposed above the plate-like structure 2.

[0039] In some embodiments, the UAV detection device includes a first reflective surface for reflecting signals located below it, thereby preventing / reducing the reception of signals from below the first reflective surface by the first antenna 3 located above it. In some embodiments, the first reflective surface may be provided by at least a portion or all of the bottom surface 11 of the housing 1. In some embodiments, the first reflective surface may be provided by at least a portion or all of the plate-like structure 2. In some embodiments, the first reflective surface may be provided by at least a portion or all of the lower surface of the plate-like structure 2. In some embodiments, two first reflective surfaces may be included, one of which is provided by at least a portion or all of the bottom surface 11 of the housing 1, and the other is provided by at least a portion or all of the lower surface of the plate-like structure 2. Exemplarily, the bottom surface 11 of the housing 1 is made of metal to form a first reflective surface, while the plate-like structure 2 is also made of metal to form another first reflective surface on its lower surface. Exemplarily, the bottom surface 11 of the housing 1 is made of metal to form a first reflective surface, while the plate-like structure 2 is made of non-metallic material. For example, the plate-like structure 2 is made of metal to form a first reflective surface on its lower surface, while the bottom surface 11 of the housing 1 is made of non-metallic material. In the above embodiment, the sidewalls 12 of the housing 1 can be made of either metal or non-metallic material.

[0040] In some embodiments, the first reflective surface may be a plane. In other embodiments, the first reflective surface may be a curved surface, such as a concave or convex curved surface. In still other embodiments, the first reflective surface may be an irregular curved surface.

[0041] In some embodiments, the UAV detection device includes a second reflective surface for reflecting signals located below and / or to the side of the second reflective surface, thereby preventing / reducing the reception of signals located below or to the side of the second reflective surface by the first antenna 3 located above or flush with the upper end of the second reflective surface. In some embodiments, the second reflective surface is provided by at least a portion or all of the sidewall 12 of the housing 1. Exemplarily, the plate-like structure 2 is made of metal, and both the bottom surface 11 and the sidewall 12 of the housing 1 are made of metal to form two first reflective surfaces and one second reflective surface. Exemplarily, the plate-like structure 2 is made of metal to form the first reflective surface, the bottom surface 11 of the housing 1 is made of non-metallic material, which allows signals to pass through the bottom surface of the housing 1 and be reflected at the first reflective surface provided by the plate-like structure 2, and the sidewall 12 of the housing 1 is made of metal to provide the second reflective surface.

[0042] In some embodiments, the second reflective surface may be a plane, for example, the second reflective surface may be perpendicular to the first reflective surface. In other embodiments, the second reflective surface may be an inclined plane, for example, the second reflective surface and the first reflective surface may form an angle to form a shell 1 structure that is wider at the top and narrower at the bottom. In still other embodiments, the second reflective surface may be an arc surface or an irregular curved surface.

[0043] In some application scenarios, drone detection equipment can be deployed at high installation locations, such as tower tops or rooftops. In these scenarios, the drone's flight altitude is typically higher than the installation location, for example, above the tower top or rooftop. Therefore, the signals the drone detection equipment needs to acquire (e.g., the target drone's RID signal) originate from above the installation location, while signals provided below the installation location are interference signals (e.g., Wi-Fi signals from adjacent buildings). In some embodiments, a first reflective surface can be used to reflect interference signals located directly below and to the side of the installation location, and a second reflective surface can be used to reflect interference signals located to the side of the installation location (e.g., Wi-Fi signals from adjacent buildings).

[0044] In some embodiments, the first antenna 3 is a built-in antenna, which is integrated inside the housing 1 of the drone detection device. In some embodiments, the first antenna 3 may be an ultra-wide vertical beam angle antenna. In some embodiments, the first antenna 3 may employ dual-band operation at 2.4 GHz and 5.8 GHz. In some embodiments, the first antenna 3 may be compatible with common RFID protocols such as Wi-Fi (802.11b / g / n / ac) and Bluetooth 5.0.

[0045] In some embodiments, the first antenna 3 can be an omnidirectional antenna, such as an omnidirectional antenna with an ultra-wide vertical beam angle. In some embodiments, the first antenna 3 is parallel to the plate structure 2. In some embodiments, the directional characteristics of the horizontally arranged omnidirectional antenna are used to suppress interference signals on the horizontal plane where the first antenna 3 is located and below the horizontal plane, thereby improving the acquisition rate of the target UAV RID signal.

[0046] In some embodiments, the vertical beam angle of the first antenna 3 with a gain of 0 dBi can be ≥160°. In some embodiments, the antenna gain of the first antenna 3 below its horizontal plane can be configured to be significantly reduced to reduce the reception of interference signals below that horizontal plane, thereby improving the SNR (Signal-to-Noise Ratio) of the target UAV RID signal. In some embodiments, the antenna gain of the first antenna 3 below its horizontal plane can be -10 to -25 dBi.

[0047] In some application scenarios, the radiation pattern of the UAV detection device can be adjusted by controlling the spacing between the first antenna 3 and the upper surface of the plate structure 2, the spacing between the plate structure 2 and the upper end of the side wall 12, and the spacing between the first antenna 3 and the upper end of the side wall 12.

[0048] It should be noted that when two of the following three factors are determined: the distance between the first antenna 3 and the upper surface of the plate structure 2, the distance between the plate structure 2 and the upper end of the side wall 12, and the distance between the first antenna 3 and the upper end of the side wall 12, the third factor is also determined. Therefore, in some application scenarios, the radiation pattern of the UAV detection equipment can be adjusted by adjusting two of the three factors.

[0049] In some embodiments, at least a portion of the upper surface of the plate-like structure 2 provides a third reflective surface. In some embodiments, the third reflective surface is used to reflect RID signals (e.g., the RID signal of a target drone) from above it. In some embodiments, the third reflective surface can reflect the RID signal from above it to the first antenna 3 so that the RID signal can be received by the first antenna 3. Therefore, adjusting the distance between the upper surface of the plate-like structure 2 and the first antenna 3 (e.g., adjusting the distance between the upper surface of the plate-like structure 2 and the upper surface of the first antenna 3 and / or the distance between the upper surface of the plate-like structure 2 and the lower surface of the first antenna 3) can adjust the radiation pattern of the drone detection device.

[0050] In some embodiments, the upper end of the side enclosure 12 may block or reflect RID signals located obliquely above the third reflective surface. In some embodiments, an excessively high side enclosure 12 may reflect the RID signal of the target UAV, while an excessively low side enclosure 12 may not effectively reflect interference signals obliquely below. Therefore, adjusting the distance between the upper end of the side enclosure 12 and the plate structure 2 can adjust the radiation pattern of the UAV detection device.

[0051] For example, a first gap exists between the plate-like structure 2 and the upper end of the side wall 12. In some embodiments, a first gap exists between the upper surface of the plate-like structure 2 and the upper end of the side wall 12. In some embodiments, the first gap ranges from 0.238 cm to 0.322 cm. In some embodiments, the first gap can be 0.238 cm, 0.239 cm, 0.24 cm, 0.245 cm, 0.26 cm, 0.278 cm, 0.282 cm, 0.29 cm, 0.305 cm, 0.31 cm, or 0.322 cm. In some embodiments, the first gap can be 0.28 cm.

[0052] For example, a second spacing is provided between the upper surface of the first antenna 3 and the upper surface of the plate structure 2. In some embodiments, the second spacing ranges from 4.811 cm to 6.509 cm. In some embodiments, the second spacing can be 4.811 cm, 4.9 cm, 5.105 cm, 5.226 cm, 5.3 cm, 5.4 cm, 5.556 cm, 5.6 cm, 5.62 cm, 5.65 cm, 5.68 cm, 5.85 cm, 6 cm, 6.2 cm, or 6.509 cm. In some embodiments, the second spacing can be 5.66 cm.

[0053] For example, a third spacing exists between the lower surface of the first antenna 3 and the upper surface of the plate structure 2. In some embodiments, the third spacing ranges from 4.751 cm to 6.428 cm. In some embodiments, the third spacing can be 4.751 cm, 4.905 cm, 5.0 cm, 5.15 cm, 5.3 cm, 5.5 cm, 5.52 cm, 5.55 cm, 5.60 cm, 5.605 cm, 5.62 cm, 5.785 cm, 6.000 cm, 6.2 cm, 6.4 cm, 6.42 cm, or 6.428 cm. In some embodiments, the third spacing can be 5.59 cm.

Figure 10This is a field diagram of the rectangular coordinates of a UAV detection device according to some embodiments of this specification, wherein the vertical axis is the antenna gain in dBi and the horizontal axis is the azimuth angle in °. Figure 11 This is a three-dimensional field diagram of a drone detection device according to some embodiments of this specification, wherein the color bar on the right indicates the antenna gain, in dBi. Figure 9 and Figure 11 In this context, the XY plane can be horizontal, with the X-axis and Y-axis directions being two directions within the horizontal plane, and the Z-axis direction being vertical. (See also...) Figures 9 to 11 As shown, in one or more embodiments of this specification, the field pattern map of the UAV detection device includes a recessed region A. In some embodiments, the field pattern map of the UAV detection device forms a recessed region A at the top. In some embodiments, the field pattern map of the UAV detection device forms a recessed region A in the 0° direction.

[0055] In some embodiments, by setting the spacing between the first antenna 3 and the upper surface of the plate structure 2, the spacing between the plate structure 2 and the upper end of the side wall 12, and the spacing between the first antenna 3 and the upper end of the side wall 12, the top position of the field pattern of the first antenna 3 is pressed down to form the recessed region 3, thereby obtaining a wider beam angle.

[0056] In some embodiments, the housing 1 may be rectangular. For example, the bottom surface 11 of the housing 1 is rectangular, and the side walls 12 of the housing 1 form a rectangular frame structure. In other embodiments, the housing 1 may also be circular or elliptical. In some embodiments, the first antenna 3 includes a first antenna substrate. In some embodiments, the first antenna substrate is rectangular and has a long side and a short side. In some embodiments, the horizontal distance between the long side of the first antenna substrate and the inner wall of the upper end of the side wall 12 of the housing 1 may be in the range of 7.1 cm to 9.7 cm.

In some embodiments, the horizontal distance between the long side of the first antenna substrate and the inner wall of the upper end of the side wall 12 of the housing 1 may be 7.97 cm. In some embodiments, the horizontal distance between the short side of the first antenna substrate and the inner wall of the upper end of the side wall 12 of the housing 1 may be in the range of 5.8 cm to 8 cm. In some embodiments, the horizontal distance between the short side of the first antenna substrate and the inner wall of the upper end of the side wall 12 of the housing 1 can be 7.3 cm. In some embodiments, the horizontal distance between the short side of the first antenna substrate and the inner wall of the upper end of the side wall 12 of the housing 1 can be 6.1 cm. In some embodiments, when the shape and size of the first antenna substrate are fixed, the horizontal distance between each side of the first antenna substrate and the inner wall of the side wall 12 of the housing 1 can be adjusted by adjusting the size of the housing 1, thereby achieving the adjustment of the radiation pattern of the first antenna 3.

In some embodiments, the distance between the first antenna 3 and the plate-like structure 2, and the distance between the first antenna 3 and the upper end of the side wall 12 of the housing 1 are adjusted by adjusting the height of the first antenna bracket 31. In some embodiments, the first antenna bracket 31 is a rod-shaped structure. In some embodiments, the height of the first antenna bracket 31 is fixed.

[0059] In some embodiments, the drone detection device further includes a housing bracket for securing the housing 1 to an installation location.

In some embodiments, a first accommodating space is formed between the plate structure 2 and the bottom surface 11 of the housing 1, and a transceiver mainboard 6 is disposed within the first accommodating space, thereby allowing the first antenna 3 and the transceiver mainboard 6 to be integrated as one unit. In some embodiments, the first accommodating space may be located inside the second accommodating space, or the first accommodating space may be a part of the second accommodating space. In some embodiments, the first antenna 3 and the second antenna are respectively signal-connected to the transceiver mainboard 6.

[0068] In some embodiments, the second antenna is an external antenna, positioned outside the housing 1 of the UAV detection device. In some embodiments, the second antenna may be a high-gain omnidirectional antenna. In some embodiments, the second antenna may employ dual-band operation at 2.4 GHz and 5.8 GHz. In some embodiments, the typical gain of the second antenna may be 5 dBi. In some embodiments, the second antenna may employ a low-noise amplifier (LNA) to reduce noise floor. In some embodiments, the second antenna can achieve long-range high-gain omnidirectional reception, avoiding signal loss of the first antenna 3 due to changes in the UAV's azimuth. In some embodiments, the second antenna is suitable for low-interference environments such as suburbs and open areas.

[0069] In some embodiments, the built-in first antenna 3 can be used to detect drones at close to medium range, and the external second antenna can be used to detect drones at long range.

[0070] In some embodiments, the drone detection device receives radio signals simultaneously via the first antenna 3 and the second antenna. After acquiring the target drone's RID signal, it analyzes and extracts key information, which is then reported to the data center via a 4G module or wired Ethernet. In some embodiments, the data center analyzes, filters, and screens the key information to obtain the drone's status information, and reports this status information to the software platform. Finally, the real-time status of the drone is dynamically displayed on the software interface.

[0071] In some embodiments, the drone detection device may include a reference signal transmitter. In some embodiments, a reference signal is transmitted from the first antenna 3 to the second antenna, or from the second antenna to the first antenna 3, to enable self-testing of the drone detection device.

[0072] In one or more embodiments of this specification, see Figure 7 As shown, the housing 1 is provided with one or more of a first antenna interface 13 and a second antenna interface 14. In some embodiments, the first antenna interface 13 may be a 4G antenna interface. In some embodiments, the second antenna interface 14 may be a Wi-Fi antenna interface. In some embodiments, the second antenna interface 14 may be an antenna for different frequency bands such as 2.4 GHz, 5.2 GHz, and 5.8 GHz. In some embodiments, the second antenna interface 14 may be a Bluetooth antenna. In some embodiments, the first antenna interface 13 and the second antenna interface 14 may also be other types of antenna interfaces. In some embodiments, the first antenna interface 13 is electrically connected to the transceiver motherboard 6. In some embodiments, the second antenna interface 14 is electrically connected to the transceiver motherboard 6. In some embodiments, the 4G antenna interface can be used to connect an external 4G antenna (i.e., the first antenna). In some embodiments, the Wi-Fi antenna interface can be used to connect an external Wi-Fi antenna (i.e., the second antenna).

[0073] In some embodiments, see Figure 7 As shown, the housing 1 is provided with one or more of a PoE interface 15 (Power over Ethernet) and a power supply interface 16. In some embodiments, the power supply interface 16 can be a DC power supply interface. In some embodiments, the PoE interface 15 is electrically connected to the transceiver motherboard 6. In some usage scenarios, drone detection equipment can be deployed on top of streetlights. In this usage scenario, streetlights and similar structures lack the foundation for power supply via the PoE interface 15. By deploying the PoE interface 15 and the DC power supply interface 16, the power supply requirements of different scenarios can be met.

[0074] In some embodiments, see Figure 7 As shown, a power switch 17 is also provided on the housing 1. In some embodiments, the power switch 17 is electrically connected to the transceiver motherboard 6 and is used to control the opening or closing of the UAV detection device.

[0075] In some embodiments, see Figure 7As shown, the housing 1 also includes an indicator light 18. In some embodiments, the indicator light 18 is electrically connected to the transceiver motherboard 6. In some embodiments, the indicator light 18 is used to indicate the status of the drone detection device, such as whether the drone detection device is powered on, whether the drone detection device has detected a drone, or whether the drone detection device has malfunctioned. In some embodiments, the indicator light 18 can remain off to indicate that the drone detection device is off. In some embodiments, the indicator light 18 can display a first color (e.g., green) to indicate that the drone detection device is on. In some embodiments, the indicator light 18 can display a second color (e.g., red) to indicate that the drone detection device has detected the target drone's RID signal. In some embodiments, the indicator light 18 can display a third color (e.g., yellow) to indicate that the drone detection device has malfunctioned.

[0076] In some embodiments, see Figure 7 As shown, the housing 1 is also provided with a waterproof and breathable valve 19. In some embodiments, the waterproof and breathable valve 19 can be a one-way valve, such as a diaphragm one-way valve, to prevent external moisture from entering the interior of the housing 1.

[0077] In some embodiments, the interior of the housing 1 is further provided with a thermally conductive silicone pad.

[0078] In some embodiments, see Figure 3 As shown, the bottom of the housing 1 is also provided with heat dissipation fins 8.

[0079] The beneficial effects that the embodiments of this specification may bring include, but are not limited to: (1) by arranging the first reflective surface to reflect the signal located below the first reflective surface, the first antenna can receive the RID signal of the target UAV located above it, avoiding interference from the interference signal below the first antenna; (2) by arranging the first spacing, the second spacing and the third spacing to adjust the field pattern of the UAV detection equipment, so that it has a wider beam angle; (3) the plate structure can form a first accommodating space with the housing to accommodate the transceiver motherboard, and can also serve as the mounting base for the first antenna, thereby realizing the integration of the first antenna and the transceiver motherboard; (4) by fixing the plate structure with the plate structure bracket, through (5) Fix the first antenna through the first antenna bracket to determine the first spacing, the second spacing, and the third spacing; (6) Connect the external second antenna through the first antenna interface and the second antenna interface; (7) Set the second antenna and make the second antenna have a different detection distance and performance than the first antenna so that the UAV detection device can be applied to different scenarios; (8) Set the second antenna to realize the self-test of the UAV detection device; (9) Set the POE interface and power supply interface to meet the power supply requirements of different scenarios; (10) Set the indicator light to indicate whether the UAV detection device is powered on, whether it has detected a UAV, and whether a fault has occurred. It should be noted that different embodiments may produce different beneficial effects. In different embodiments, the beneficial effects that may be produced can be any one or a combination of the above, or any other possible beneficial effects.
