Flight control method and system and unmanned aerial vehicle

Abstract

The invention discloses a flight control method and system and an unmanned aerial vehicle. The method includes the steps that current electricity quantity information (101) of a battery of the unmanned aerial vehicle is obtained; when the current electricity quantity information meets a first electricity quantity alarming condition, the current state (102) of the unmanned aerial vehicle is obtained; according to the current state of the unmanned aerial vehicle, the unmanned aerial vehicle is controlled to be in a corresponding safe protection mode, and when the current state is an aerial flight state, the unmanned aerial vehicle is controlled to be in a landing state; if the current state is a non-lift-off state, the unmanned aerial vehicle is controlled to be in a shutdown mode (103). When it is detected that the unmanned aerial vehicle is under a low-electricity quantity condition, the unmanned aerial vehicle is controlled to be in the safe protection mode corresponding to the current state, in this way, the flight safety of the unmanned aerial vehicle is guaranteed, and the probability of crash of the unmanned aerial vehicle is lowered.

Description

[0001] This application is a divisional application with the application number 201680003238.7, the application date is March 1, 2016, and the invention title is flight control method, system and unmanned aerial vehicle. technical field [0002] Embodiments of the present invention relate to the field of unmanned aerial vehicles, and in particular to a flight control method, system and unmanned aerial vehicle. Background technique [0003] Unmanned aerial vehicles such as drones have been widely used in fields such as aerial photography and reconnaissance. During the actual flight, due to the continuous consumption of the battery power of the unmanned aerial vehicle, it often happens that the battery power is not enough to support the continued flight of the unmanned aerial vehicle. [0004] In order to avoid the safety hazard of the unmanned aerial vehicle crash caused by continuous control of the unmanned aerial vehicle flight due to the user not knowing the battery power ...

AI Technical Summary

Problems solved by technology

During the actual flight, due to the continuous consumption of the battery power of the UAV, it often happens that the battery power is not enough to support the continued flight of the UAV

[0004] In order to avoid the safety hazard of the unmanned aerial vehicle crash caused by continuous control of the unmanned aerial vehicle flight due to the user not knowing the battery power consumption, most unmanned aerial vehicles currently provide a battery power reminder method to remind the user Current remaining battery power

[0005] However, in practical applications, such a situation often occurs: when the user controls the flight of the UAV, it is easy to ignore the low battery prompt and still control the flight of the UAV. For the sake of protecting the battery, when the battery power is lower than a certain threshold, the battery The management system cut off the battery output, causing the crash

To sum up, at present, under the condition of low battery, unmanned aerial vehicles still have hidden dangers in safe flight
