[0023] In the technical solution of this application, the UAV signal receiving device 100 includes a first omnidirectional antenna 122, a second omnidirectional antenna 124, and a third omnidirectional antenna 126. The angle between each pair of the first omnidirectional antenna 122, the second omnidirectional antenna 124, and the third omnidirectional antenna 126 is in the range of 60 degrees to 120 degrees. By combining at least three omnidirectional antennas arranged in different directions, it can be ensured that the superimposed antenna lobe pattern is close to spherical, thereby reducing the detection blind zone and expanding the detection range, so as to achieve effective tracking and monitoring of UAVs.

[0024] In the embodiments of this application, the angles between any two of the first omnidirectional antenna 122, the second omnidirectional antenna 124, and the third omnidirectional antenna 126 are within the range of 60 degrees to 120 degrees. This means that the angles between the first omnidirectional antenna 122 and the second omnidirectional antenna 124, the first omnidirectional antenna 122 and the third omnidirectional antenna 126, and the second omnidirectional antenna 124 and the third omnidirectional antenna 126 are all within the range of 60 degrees to 120 degrees. The angle between two omnidirectional antennas can be the angle between the extending directions of the two omnidirectional antennas.

[0025] In some embodiments, the angles between any two of the first omnidirectional antenna 122, the second omnidirectional antenna 124, and the third omnidirectional antenna 126 can be in the range of 80 to 100 degrees. Preferably, in some embodiments, the first omnidirectional antenna 122, the second omnidirectional antenna 124, and the third omnidirectional antenna 126 are perpendicular to each other, thereby making the superimposed antenna lobe pattern essentially spherical, achieving the maximum possible detection range. In use, the first omnidirectional antenna 122 can be vertically upward, while the second omnidirectional antenna 124 and the third omnidirectional antenna 126 can be oriented towards two mutually perpendicular horizontal directions.

[0026] The number of the first omnidirectional antenna 122, the second omnidirectional antenna 124, and the third omnidirectional antenna 126 may be one or more. In some embodiments, the first omnidirectional antenna 122, the second omnidirectional antenna 124, and the third omnidirectional antenna 126 may be used to receive RID (Remote ID) signals, and the UAV signal receiving device 100 may also include antennas of other types and / or uses.

[0027] The body 110 may include a housing and a processor disposed within the housing, the processor being capable of processing signals received by the antenna. Figure 1 In the exemplary embodiment shown, the first omnidirectional antenna 122 is connected to the top surface of the body 110, and the second omnidirectional antenna 124 and the third omnidirectional antenna 126 are connected to the bottom surface of the body 110. It should be understood that the first omnidirectional antenna 122, the second omnidirectional antenna 124, and the third omnidirectional antenna 126 can be connected to other parts of the body 110 as needed.

[0028] exist Figure 1 In the illustrated embodiment, the first omnidirectional antenna 122, the second omnidirectional antenna 124, and the third omnidirectional antenna 126 are integrated with the body 110, forming a unified structure. This arrangement facilitates the installation and management of the UAV signal receiving device 100. (Reference) Figure 2 The integrated UAV signal receiver 100 can be installed on the support structure 12 (such as a tower, pole, etc.) using a unified mounting component.

[0029] In some embodiments, the extension directions of the first omnidirectional antenna 122, the second omnidirectional antenna 124, and / or the third omnidirectional antenna 126 are adjustable. One or more of the first omnidirectional antenna 122, the second omnidirectional antenna 124, and the third omnidirectional antenna 126 can be rotatably connected to the body 110, allowing a single antenna to rotate about one or more axes to adjust its orientation. This allows for adjustment of the antenna position to adapt to different installation environments and avoid interference with external equipment.

[0030] In some embodiments of this application, the UAV signal receiving device 100 can be integrated with other communication equipment (e.g., communication equipment of operator base stations and vehicle-to-everything (V2X) roadside base stations), sharing support structures such as towers and poles, thus utilizing existing site resources and saving construction costs. In this case, the UAV signal receiving device 100 can be further configured to obtain power from other communication equipment to save power connection resources or to cope with situations where no independent power supply is available. In some embodiments, the body 110 has a power supply interface 112 for PoE (Power over Ethernet) power supply, which is used to connect to a specific network cable 113. Using PoE power supply to power the UAV signal receiving device 100 through other communication equipment can meet the voltage requirements of the input and output ends to achieve smooth power supply, and can also save wiring costs and reduce installation complexity. In a specific embodiment, the power supply interface 112 can be connected to the RRU (Remote Radio Unit) of the operator base station through a specific network cable 113 to obtain power.

[0031] Figure 3 A schematic diagram of a drone signal receiving device 200 according to another embodiment of the present invention is shown. For simplicity, components in the drone signal receiving device 200 that are the same as or similar to components in the drone signal receiving device 100 are referred to with the same or similar designations, and reference can be made to the above description of the drone signal receiving device 100. Reference Figure 3In the UAV signal receiving device 200, the first omnidirectional antenna 222, the second omnidirectional antenna 224 and the third omnidirectional antenna 226 are separated from the body 210; the UAV signal receiving device 200 also includes a plurality of signal transmission lines 230, each signal transmission line 230 connecting one of the first omnidirectional antenna 222, the second omnidirectional antenna 224 and the third omnidirectional antenna 226 to the body 210.

[0032] By employing a separate design, multiple omnidirectional antennas can be installed in locations far from interference sources. In some cases, interference signals may exist near the location where the drone 210 is installed. In such cases, the omnidirectional antennas can be installed away from the drone 210 in an interference-free location. In one specific embodiment, the drone 210 is installed on a support pole located on the side of a rooftop near a wall. However, there are interfering Wi-Fi signals at the wall (the frequency band of the RFID signal transmitted by the drone is the same as that used by Wi-Fi, Bluetooth, microwave ovens, etc., thus causing interference). In this embodiment, multiple omnidirectional antennas can be installed in the middle of the rooftop, away from the wall, to avoid interference caused by Wi-Fi signals. The drone 210 can be installed on the support pole together with other communication devices, sharing installation resources. In some embodiments, the signal transmission line 230 may be provided with a length adjustment component, thereby adjusting the length of the signal transmission line 230 to adapt to different situations, thereby adjusting the distance between the drone 210 and the omnidirectional antenna, so that the omnidirectional antenna can be guided to a location far from interference sources.

[0033] refer to Figure 3 In some embodiments, the UAV signal receiving device 200 further includes an antenna mounting base 240 separate from the body 210, on which a first omnidirectional antenna 222, a second omnidirectional antenna 224, and a third omnidirectional antenna 226 are mounted. The antenna mounting base 240 facilitates the unified installation of multiple omnidirectional antennas. The first omnidirectional antenna 222, the second omnidirectional antenna 224, and the third omnidirectional antenna 226 can be mounted on the antenna mounting base 240 at a predetermined angle (e.g., vertically) between each other.

[0034] Figure 4 and Figure 5 A schematic diagram of a drone signal receiving device 300 according to another embodiment of the present invention is shown. For simplicity, components in the drone signal receiving device 300 that are the same as or similar to components in the drone signal receiving device 100 are referred to with the same or similar designations, and reference can be made to the above description of the drone signal receiving device 100. Reference Figure 4 and Figure 5The UAV signal receiving device 300 includes: multiple signal transmission lines 330, each signal transmission line 330 connecting one of the first omnidirectional antenna 322, the second omnidirectional antenna 324, and the third omnidirectional antenna 326 to the body 310; an antenna mounting base 340 with a receiving cavity 342, on which the first omnidirectional antenna 322, the second omnidirectional antenna 324, and the third omnidirectional antenna 326 are mounted, and the antenna mounting base 340 has an engaged state and a disengaged state; as shown Figure 4 As shown, when in the engaged state, the antenna mounting base 340 is engaged with the body 310, and the signal transmission line 330 is housed in the receiving cavity 342; as Figure 5 As shown, when in the separated state, the antenna mount 340 is separated from the body 310, and the signal transmission line 330 extends at least partially outside the housing 342.

[0035] This configuration enhances the adaptability of the UAV signal receiver 300. When there is no interference signal at the installation location of the fuselage 310, the antenna mount 340 can be switched to the engaged state. In this state, the UAV signal receiver 300 is an integrated structure that can be installed uniformly, with the signal transmission line 330 stored in the storage cavity 342 for easy management and aesthetic purposes. When there is interference signal at the installation location of the fuselage 310, the antenna mount 340 can be switched to the disengaged state, allowing multiple omnidirectional antennas to be moved from the fuselage 310 to an interference-free location. In this state, the signal transmission line 330 extends from the storage cavity 342 to provide the required connection length. The antenna mount 340 can be detachably connected to the fuselage 310 to switch between the engaged and disengaged states.

[0036] refer to Figure 2 This application also proposes a communication base station 10, including: a support structure 12; a drone signal receiving device 100 disposed on the support structure 12; and at least one other communication device. The power supply interface 112 of the drone signal receiving device 100 can be connected to other communication devices via a power supply line (e.g., a specific network cable 113 for PoE power supply). Although... Figure 2 The drone signal receiver is shown as Figure 1 The illustrated embodiment shows a drone signal receiving device 100; however, it should be understood that the drone signal receiving device included in the communication base station can also be the drone signal receiving device in other embodiments. For example, when the communication base station includes a drone signal receiving device 200, the body 210 can be disposed on a support structure, while multiple omnidirectional antennas are separated from the body and disposed at a location away from interference signals.
