Embodiment 1

[0060] refer to figure 1 and figure 2 , provides a schematic diagram of the overall structure of an automatic tracking antenna pan-tilt system based on Beidou positioning, as shown in figure 1 A Beidou positioning-based automatic tracking antenna cloud platform system includes a UAV terminal 100, including an acquisition unit 101, a transmission unit 102 connected to the acquisition unit 101, and an unmanned aerial vehicle 103. The acquisition unit 101 and the transmission unit 102 are both arranged on On the drone 103; and, the ground cloud platform terminal 200 includes a receiving unit 201, a control unit 202 connected to the receiving unit 201, and a response unit 203 connected to the control unit 202, and the receiving unit 201 establishes a connection with the transmission unit 102.

[0061] Specifically, the main structure of the present invention includes the UAV end 100 and the ground cloud platform end 200. By cooperating between the set UAV end 100 and the ground ...

Embodiment 2

[0065] refer to figure 2 This embodiment is different from the first embodiment in that: the ground pan-tilt terminal 200 includes a receiving unit 201, a control unit 202 connected to the receiving unit 201, and a response unit 203 connected to the control unit 202, the receiving unit 201 and the transmission unit 102 to establish a connection, and the area array antenna can be calibrated through the dual Beidou positioning, which improves the accuracy of automatic tracking of the gimbal and ensures the clarity of the returned image. Specifically, the second lora data transmission module 201a and the area array antenna 201b of the receiving unit 201 respectively receive the first Beidou positioning information of the first Beidou positioning module 101a and the image acquisition information of the image acquisition module 101b through wireless communication; The second Beidou positioning information collected by the second Beidou positioning module 204, the first Beidou posi...

Embodiment 3

[0068] refer to figure 2 , this embodiment is different from the first embodiment in that: this solution is an automatic tracking antenna pan-tilt method based on Beidou positioning, including steps,

[0069] S1: The drone terminal 100 sends the first Beidou positioning information through the first lora data transmission module 102a, and at the same time sends the image acquisition information to the ground cloud platform terminal 200 through the image transmission antenna 102b;

[0070] S2: The second lora data transmission module 201a of the ground platform terminal 200 receives the first Beidou positioning information through wireless communication.

[0071] S3: The control unit 202 of the ground pan / tilt terminal 200 receives the first Beidou positioning information and the second Beidou positioning information through the wiring, and determines whether initial calibration is required;

[0072] Further, the control unit 202 of the ground pan / tilt terminal 200 receives t...

Abstract

The invention discloses an automatic tracking antenna pan-tilt system based on Beidou positioning, and the system comprises an unmanned plane end which comprises an acquisition unit, a transmission unit connected with the acquisition unit, and an unmanned plane, wherein the acquisition unit and the transmission unit are both disposed on the unmanned plane; a ground cradle head end which comprisesa receiving unit, a control unit connected with the receiving unit and a response unit connected with the control unit, wherein the receiving unit is connected with the transmission unit; the acquisition unit comprises a first Beidou positioning module and an image acquisition module, and the first Beidou positioning module is used for acquiring first Beidou positioning information of the unmannedaerial vehicle. Through Beidou positioning, the position of the unmanned aerial vehicle can be tracked more accurately, the area array antenna is matched, it is ensured that the approximate trackingposition is correct, the unmanned aerial vehicle is always within the radiation range through rotation of the steering engine, and the control stability of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of pan-tilt tracking, in particular to an automatic tracking antenna pan-tilt system based on Beidou positioning. Background technique [0002] In the electric power industry, UAV inspections have outstanding advantages, and the efficiency is 40 times higher than traditional manual inspections. It also eliminates many risks for the staff of electric power companies; Disaster monitoring, weather detection, air traffic control, border patrol monitoring, communication relay, pesticide spraying, etc. UAVs are also widely used in the military field. [0003] However, in the process of actual use, due to the influence of complex scenes, the operability of UAVs is greatly reduced, out-of-control crashes, image transmission and control signals are easily interfered, etc., and when the UAV deviates from the control receiver The intensity is greatly reduced, and the returned image is blurred, resulting in operational...
