In this application.

Technical field

The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial system and a method for controlling an unmanned aerial system.

Background technique

UAVs are now more and more widely used in aerial photography, reconnaissance, public security / firefighting / traffic / emergency rescue, customs border defense / sea surveillance inspection, real-time broadcast / on-site monitoring, power line inspection / pipeline inspection, plant protection, etc. Has been widely used. For drone cruise monitoring in a large area, the following networking technologies currently exist.

The first is to use a drone as a relay and extend the data transmission distance and coverage area through WIFI and other drone networks; however, the bandwidth between the drone and the ground station as a relay is limited. It is impossible to send real-time high-definition images of all drones to the ground at the same time, and the ground station cannot control all drones at the same time.

The second is to deploy multiple ground stations in a distributed manner to control the drone flight. When the drone detects that the communication signal with a certain ground station is good, it switches to the connection with this ground station. However, this solution requires network switching between the drone and multiple ground stations, which is very complicated to implement; and the area covered by the drone is small due to the power limitation.

The third is to control the drone through the public 3/4 / 5G network, to control the drone's flight and real-time video surveillance from a long distance. This solution requires the use of mobile communication base stations to communicate with the drone; but no Human aircraft generally fly higher than the base station, and the signal of the base station is generally transmitted horizontally, so the signal between the base station and the drone will have a high probability and is bad, which directly affects the control and video transmission of the drone.
