Unmanned aerial vehicle communication enhancement method and unmanned aerial vehicle

Abstract

The invention relates to a communication method of an unmanned aerial vehicle and the unmanned aerial vehicle. The method is applied to the unmanned aerial vehicle provided with an azimuth tracking device, and an array antenna is arranged on the azimuth tracking device. The method comprises the following steps: initializing the orientation of the orientation tracking device and the direction of asignal beam of the array antenna; acquiring position state information of the unmanned aerial vehicle; controlling the azimuth tracking device to deflect on a horizontal plane according to the position state information; controlling the array antenna to adjust the angle of a signal beam on a vertical plane according to the position state information; and sending the signal through the array antenna. According to the scheme, directional signal transmission is carried out by adopting the array antenna, so that the antenna gain can be greatly improved, the signal coverage range is increased, andthe antenna can be used for transmitting high-definition images. Position tracking of the array antenna is decomposed into a horizontal plane and a vertical plane for control, and the complexity of tracking control is reduced.

Description

technical field [0001] The present application relates to the technical field of wireless communication of drones, and in particular to a communication method of drones and drones. Background technique [0002] With the development of automatic control and artificial intelligence technology, the application fields of UAVs are becoming more and more extensive, and the application environment of UAVs is becoming more and more complex. Higher requirements are put forward for video transmission distance, resolution, and channel capacity than before. Require. During the flight of the drone in the air, the wireless communication signal will suffer loss during the propagation process, and the loss on the propagation path is proportional to the propagation distance. [0003] The attenuation of the signal makes the video transmission distance of the drone shorter, the video quality deteriorates, and even the video signal cannot be received at all. In order to reduce the impact of s...

Problems solved by technology

[0007] However, the weight and volume of the directional antenna itself are relatively large, and the servo tracking equipment is heavy, consumes a lot of power, and has a slow tracking speed. It is difficult for its tracking speed to match the speed of the UAV.

However, the beamforming algorithm is very complex and requires a lot of computing resources, resulting in slow tracking speed and high requirements on hardware performance.
