Abstract

The invention discloses an unmanned aerial vehicle communication control method. The unmanned aerial vehicle communication method comprises the following steps: reading first position information in a positioning module and first antenna angle information indicated by an electronic compass by a control terminal; according to the first position information and received second position information of an unmanned aerial vehicle, calculating so as to obtain relative position of the unmanned aerial vehicle relative to the control terminal; according to the first antenna angle information and the relative position of the unmanned aerial vehicle relative to the control terminal, generating a control signal for controlling a driving module to drive a first antenna to point to the unmanned aerial vehicle. By adopting the scheme, the communication power consumption of the unmanned aerial vehicle and the control terminal can be reduced, the endurance capacity of the unmanned aerial vehicle is improved, the communication distance can be increased, and the communication interference of communication signals to an ambient environment can be also reduced.

Description

technical field [0001] Embodiments of the present invention relate to unmanned aerial vehicle technology, and in particular to a communication control method and device for an unmanned aerial vehicle. Background technique [0002] During the flight, the UAV will communicate with the ground control terminal in real time. For example, the control terminal transmits flight instructions to control the flight of the UAV, and the UAV sends the images and videos it takes to the control terminal for storage or direct display. [0003] In the communication process of existing drones, traditional omnidirectional antennas are used to send and receive communication signals (such as control signals, data transmission signals, and image transmission signals). That is, the control terminal uses an omnidirectional antenna to transmit omnidirectional communication signals to space, and the UAV receives signals within the effective communication distance of the control terminal signal. The d...
