Unmanned aerial vehicle (UAV) system and control method thereof

Abstract

The invention discloses a UAV system and a control method thereof. The UAV system is used to execute a task within a task area, and the task area is divided into subareas; the system comprises UAVs, ground stations and a control platform, the ground stations are in one-to-one correspondence with the subareas, and the ground stations are in communication connection with the UAVs in one to one correspondence; and the ground stations obtain an execution instruction from the control platform, and the ground station which obtains the execution instruction controls the corresponding UAV to execute the task in the corresponding subarea according to the execution instruction. The single UAV includes the bandwidth with the corresponding ground station independently, transmission of large data amount can be satisfied fully, flight subareas of the UAVs are relatively small, and hang time is longer; and a UAV task can be realized in a wider task area as wide-area monitoring in a better way.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle system and an unmanned aerial vehicle system control method. Background technique [0002] UAVs are now more and more widely used in aerial photography, reconnaissance, public security / fire protection / traffic / emergency rescue, customs border defense / marine surveillance inspection, real-time broadcast / on-site monitoring, power line inspection / pipeline inspection line, plant protection, etc. widely used. For the drone cruise monitoring in a large area, the current networking technologies are as follows. [0003] The first is to use a UAV as a relay to network with other UAVs through WIFI to expand the data transmission distance and coverage area; however, the bandwidth between the UAV as a relay and the ground station is limited. It is impossible to send real-time high-definition images of all UAVs to the ground at the same time, and the ground s...

Problems solved by technology

However, this solution requires network switching between the UAV and multiple ground stations, which is very complicated to implement; and due to the limitation of power, the area covered by the UAV is small

[0005] The third is to control the UAV through the public 3/4/5G network for long-distance control of UAV flight and real-time video surveillance. This solution needs to use the base stat
