Problems solved by technology
[0003] In the process of realizing the present invention, the inventor found that the existing unmanned aerial vehicle is controlled by an independent flight controller, thus, when the flight controller is abnormal or malfunctions, the unmanned aerial vehicle enters an out-of-control state at this time, As a result, the occurrence of the crash accident brought unnecessary economic losses and potential safety hazards.

The invention discloses a flight control method and system for an unmanned aerial vehicle. At least two flight controllers are arranged in the system in a redundancy mode. Besides, the method comprises: equipment configuration information of all flight controller is obtained; according to the equipment configuration information of all flight controller, whether a current flight controller is a main flight controller is determined; if so, synchronization processing is carried out on unmanned aerial vehicle flight state data and / or unmanned aerial vehicle task configuration data of the main flight controller; and if the data after synchronization processing are issued to all standby flight controllers, so that all standby flight controllers carry out back-up processing on the unmanned aerial vehicle flight state data and / or unmanned aerial vehicle task configuration data. Therefore, on the basis of redundancy setting of the flight controllers, availability and stability of the unmanned aerial vehicle flight control system are improved effectively.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method and system for controlling the flight of an unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aerial vehicle controlled by radio remote control equipment or its own program control device. With the development of science and technology, UAV technology is becoming more and more mature. UAVs are widely used for their fast speed, flexible operation, wide range of uses, low cost, and good maneuverability. They not only play an extremely important role in modern warfare , and has broad prospects in the civilian field. [0003] In the process of realizing the present invention, the inventor found that the existing unmanned aerial vehicle is controlled by an independent flight controller, thus, when the flight controller is abnormal or malfunctions, the unmanned aerial vehicle enters an out-of-contro...
