Flight control method for unmanned aerial vehicle, device and unmanned aerial vehicle

Abstract

The embodiments of the present invention provide a flight control method for an unmanned aerial vehicle, a flight control device for an unmanned aerial vehicle and an unmanned aerial vehicle. The method includes the following steps that: the unmanned aerial vehicle autonomously flies along a preset flight track and performs plant protection operation; when receiving first remote control signals sent by a remote control device, the unmanned aerial vehicle generates the target flight speed of the unmanned aerial vehicle according to the first remote control signals; the unmanned aerial vehicle stops the plant protection operation, and flies away from the flight track according to the target flight speed; and when receiving second remote control signals sent by the remote control device, theunmanned aerial vehicle returns to the flight track. According to the flight control method and the flight control device of the invention, the remote control device is manually operated so as to perform auxiliary control on the flight operation of the unmanned aerial vehicle, so that the unmanned aerial vehicle can conveniently avoid obstacles temporarily appearing in the flight track, and timelyfly back to the flight track after avoiding the obstacles so as to continue to fly, and therefore, the flexibility of the work of the unmanned aerial vehicle is enhanced, the efficiency of the work of the unmanned aerial vehicle is improved, and the effect of the work is ensured.

Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to a flight control method for an unmanned aerial vehicle, a flight control device for an unmanned aerial vehicle, and an unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as Unmanned Aerial Vehicle (UAV), is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device. UAVs are widely used and are often used in agricultural plant protection, urban management, geology, meteorology, electric power, emergency rescue and disaster relief, video shooting and other industries. [0003] Taking UAV plant protection as an example, when UAVs perform plant protection operations, there are currently two ways of autonomous flight and manual UAV flight. When flying autonomously, the UAV flies completely according to the predetermined route without human intervention; while when the UAV ...

AI Technical Summary

Problems solved by technology

The former is easy to operate and can achieve precise operation, but less flexible

Accurate and fine routes must be planned in advance to ensure that the UAV can automatically avoid fixed obstacles in the farmland during the flight; in addition, when flying autonomously according to the predetermined route, if there are temporary obstacles such as birds in the farmland, It is difficult for drones to automatically avoid obstacles, and it is prone to flight accidents where drones collide with obstacles

If the method of manual control of unmanned flight is adopted, although temporary obstacles can be avoided in time, due to the need for the operator to participate in the whole process, not only the operator's technical requirements are high, but also in the actual flight process, the drone's The flight direction is easy to deviate, and it is difficult for the operator to judge the resulting error, which can easily cause missed spraying or re-spraying, which will affect the operation effect
