[0028] like Figures 1 to 4 As shown, an electronically assisted training and testing device for unmanned aerial vehicles (UAVs) according to a first aspect embodiment of the present invention includes a support rod 100, a control box 200, a main control module 300, a wireless transmission module 400, a first dynamic positioning antenna 500, a second dynamic positioning antenna 600, and a connecting module. The control box 200 is disposed on the support rod 100, and the main control module 300 is disposed within the control box 200. The main control module 300 includes a dynamic positioning unit 310. The wireless transmission module 400 is disposed in the control box 200 and connected to the main control module 300. The first dynamic positioning antenna 500 is disposed at the head end of the support rod 100, and the second dynamic positioning antenna 600 is disposed at the tail end of the support rod 100. The dynamic positioning unit 310 is connected to both the first dynamic positioning antenna 500 and the second dynamic positioning antenna 600. The connecting module is disposed on the support rod 100 and is used to mount the support rod 100 onto the UAV frame.

[0029] The support rod 100 can be a straight, long rod made of alloy or resin material. The support rod 100 can be composed of a single rod or multiple rods spliced ​​together.

[0030] The dynamic positioning unit 310 can be a conventional RTK positioning chip and its auxiliary circuits. The first dynamic positioning antenna 500 and the second dynamic positioning antenna 600 simultaneously receive carrier phase signals transmitted by the same group of satellites (such as GPS, Beidou, GLONASS).

[0031] There is a time difference in the path of the satellite signal to the first dynamic positioning antenna 500 and the second dynamic positioning antenna 600, resulting in different carrier phases. The RTK positioning chip calculates the phase difference (Δ... By combining the baseline length (L) and the satellite azimuth geometry, the heading angle (θ) of the UAV is calculated. Specifically:

[0032] θ=arccos(Δ λ / 2πL), where λ is the carrier wavelength.

[0033] Specifically, carrier phase signals can be obtained directly from satellite signals transmitted by conventional operators for 4G and 5G mobile communications.

[0034] In some embodiments of this utility model, such as Figure 4 As shown, the wireless transmission module 400 includes a mobile communication unit 410 and a mobile communication antenna 420.

[0035] The mobile communication unit 410 can be a conventional 4G or 5G mobile communication chip and its associated circuits. The mobile communication unit 410 acquires or transmits wireless signals through the mobile communication antenna 420.

[0036] The main control module 300 includes an MCU or CPU and its auxiliary modules. The control box 200 can be made of alloy or resin material. A circuit board is provided inside the control box 200. The main control module 300 and the mobile communication unit 410 can be set on the circuit board.

[0037] In some embodiments of this utility model, an angular velocity sensor 700 is provided inside the control box 200, and the angular velocity sensor 700 is connected to the main control module 300.

[0038] The angular velocity sensor 700 can be a conventional gyroscope or other types of angular velocity sensor 700. The angular velocity sensor 700 is set in the control box 200. The angular velocity sensor 700 can detect the tilt angle of the UAV. The main control module 300 can obtain the tilt angle information and heading angle information and then send them to the monitoring platform through the wireless transmission module 400 so that the monitoring platform can evaluate and score the UAV based on its flight status.

[0039] In some embodiments of this utility model, the control box 200 also includes a storage battery that supplies power to each main control module 300, wireless transmission module 400, first dynamic positioning antenna 500, second dynamic positioning antenna 600, angular velocity sensor 700, etc. The surface of the control box 200 is also provided with a display screen 900, through which the main control module 300 can display information such as the storage capacity of the storage battery and the wireless signal strength.

[0040] This utility model relates to an electronically assisted training and testing device for unmanned aerial vehicles (UAVs). A support rod 100 is attached to the UAV frame via a connecting module, allowing operators to disassemble and install the flight attitude detection device independently without easily damaging the UAV frame. A first dynamic positioning antenna 500 and a second dynamic positioning antenna 600 can be installed at either end of the support rod 100. The first and second dynamic positioning antennas 500 and 600 respectively receive wireless carrier signals. The dynamic positioning unit 310 calculates the phase difference between the wireless carrier signals received by the first and second dynamic positioning antennas 500 and 600 to determine the UAV's heading angle during flight. The main control module 300 then transmits the heading angle to the monitoring platform via a wireless transmission module 400. This design improves positioning accuracy, optimizes disassembly and assembly efficiency, and reduces maintenance costs.

[0041] In some embodiments of this utility model, such as Figure 1 , 3 As shown, the support rod 100 includes a first rod 110 and a second rod 120, both of which are hollow. The first end of the first rod 110 passes through the first side of the control box 200, and the first end of the second rod 120 passes through the second side of the control box 200. The first side and the second side face each other. The first dynamic positioning antenna 500 is disposed at the tail end of the first rod 110. The first dynamic positioning antenna 500 is connected to the dynamic positioning unit 310 through a first wire passing through the first rod 110. The second dynamic positioning antenna 600 is disposed at the tail end of the second rod 120. The second dynamic positioning antenna 600 is connected to the dynamic positioning unit 310 through a second wire passing through the second rod 120.

[0042] The control box 200 can be rectangular. The first rod 110 and the second rod 120 are connected to the opposite first and second sides, respectively, to ensure that the first rod 110 and the second rod 120 are kept as straight as possible. The control box 200 can be connected to the first rod 110 and the second rod 120 by screws, rivets or clips. Since the first rod 110 and the second rod 120 are both hollow, the first wire can be routed in the first rod 110 and the second wire can be routed in the second rod 120. The wiring is stable and reliable and the overall structure is compact.

[0043] In some embodiments of this utility model, the first dynamic positioning antenna 500 is provided with a first sleeve 510, which is sleeved on the end of the first rod 110. The first dynamic positioning antenna 500 is vertically arranged on the first sleeve 510 and can be configured to be perpendicular to the support rod 100 to stably receive carrier phase signals. The first sleeve 510 can be connected to the support rod 100 by screws, rivets or buckles.

[0044] According to some embodiments of the present invention, a second sleeve 610 is provided on the second dynamic positioning antenna 600. The second sleeve 610 is sleeved on the end of the second rod 120. The second dynamic positioning antenna 600 is vertically arranged on the second sleeve 610 and can be set to be perpendicular to the support rod 100 to stably receive carrier phase signals.

The multiple connection components 800 are connected to the support rod 100 along the length direction of the support rod 100, thereby ensuring that the support rod 100 is stably connected in the length direction and ensuring that the positions of the first dynamic positioning antenna 500 and the second dynamic positioning antenna 600 are relatively fixed, so as to improve the measurement accuracy of the heading angle.

[0046] In some embodiments of this utility model, such as Figure 2 As shown, the connecting assembly 800 includes a first clamp 810, a second clamp 820, and a connecting seat 830. The connecting seat 830 is connected to the first clamp 810 and the second clamp 820 respectively. The first clamp 810 is sleeved on the support rod 100, and the second clamp 820 is used to connect to the UAV frame.

[0047] The first clamp 810 is fitted onto the support rod 100 for a tight connection, and the drone frame also has a rod-type frame. The second clamp 820 can be fitted onto the drone frame for a tight connection, thereby ensuring that the flight attitude detection device is securely mounted on the drone.

[0048] In some embodiments of this utility model, the first clamp 810 includes a first clamp arm 811, a second clamp arm 812, a first support arm 813, and a first driven arm 814. The first clamp arm 811 is connected to the connecting seat 830. The first end of the first clamp arm 811 is hinged to the first end of the first support arm 813, and the tail end of the first clamp arm 811 is hinged to the first end of the second clamp arm 812. The tail end of the second clamp arm 812 is provided with a first through hole, and the first support arm 813 passes through the first through hole. The first driven arm 814 is hinged to the tail end of the first support arm 813. The first driven arm 814 can press against the second clamp arm 812 to drive the tail end of the second clamp arm 812 to approach the head end of the first clamp arm 811.

[0049] The user can apply force to the first driven arm 814 to make the first driven arm 814 swing. The first driven arm 814 has a first abutment part. When the first driven arm 814 rotates to a certain position, the first abutment part will press against the second hoop arm 812. The second hoop arm 812 moves along the length direction of the first support arm 813, so that the tail end of the second hoop arm 812 is close to the head end of the first hoop arm 811, so that the first hoop arm 811 and the second hoop arm 812 are tightly sleeved on the support rod 100.

[0050] In some embodiments of this utility model, the second clamp 820 includes a third clamp arm 821, a fourth clamp arm 822, a second support arm 823, and a second driven arm 824. The third clamp arm 821 is connected to the connecting seat 830. The first end of the third clamp arm 821 is hinged to the first end of the second support arm 823. The last end of the third clamp arm 821 is hinged to the first end of the fourth clamp arm 822. The last end of the fourth clamp arm 822 is provided with a second through hole. The second support arm passes through the second through hole. The second driven arm is hinged to the last end of the second support arm 823. The second driven arm 824 can press against the fourth clamp arm 822 to drive the last end of the fourth clamp arm 822 to approach the first end of the third clamp arm 821.

[0051] Similarly, the user can apply force to the second driven arm 824 to make the second driven arm 824 swing. The second driven arm 824 has a second abutment. When the second driven arm 824 rotates to a certain position, the second abutment will press against the fourth hoop arm 822. The fourth hoop arm 822 moves along the length direction of the second support arm 823, so that the tail end of the fourth hoop arm 822 is close to the head end of the third hoop arm 821, so that the third hoop arm 821 and the fourth hoop arm 822 are tightly connected to the support rod 100. Specifically, the third hoop arm 821 and the first hoop arm 811 are relatively fixed, which can make the position between the support rod 100 and the UAV frame relatively stable.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
