Fault monitoring early-warning method of unmanned aerial vehicle and unmanned aerial vehicle

Abstract

The embodiment of the invention provides a fault monitoring early-warning method of an unmanned aerial vehicle and the unmanned aerial vehicle, and belongs to the field of the unmanned aerial vehicle.The method comprises the following steps: acquiring acceleration data of the unmanned aerial vehicle; and determining whether to give early-warning according to the condition whether the accelerationdata exceeds a set threshold. And meanwhile, the invention further provides an unmanned aerial vehicle adopting the fault monitoring early-warning method. By monitoring the acceleration data, especially the abnormity of the triaxial acceleration data, the excessive fuselage jittering and like accident potential can be timely discovered, thereby improving the flight security of the unmanned aerialvehicle.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a fault monitoring and early warning method for unmanned aerial vehicles and an unmanned aerial vehicle. Background technique [0002] Multi-rotor drones are a common type of unmanned aerial vehicles currently on the market, generally consisting of three or more propellers. The flight controller in the unmanned aerial vehicle cooperates with the inertial measurement system to obtain various flight status information collected by the inertial measurement system in real time. The flight controller responds in time by controlling the power system of the unmanned aerial vehicle, so that the unmanned aerial vehicle can maintain stability. The flight attitude and the flight action corresponding to the operation command. [0003] In the industrial application of unmanned aerial vehicles, due to the long operating hours of unmanned aerial vehicles, poor operating environment, and...

AI Technical Summary

Problems solved by technology

[0003] In the industrial application of unmanned aerial vehicles, due to the long operating hours of unmanned aerial vehicles, poor operating environment, and insufficient maintenance, etc., there will often be loose body of unmanned aerial vehicles, loose screws, poor arm fixing, motor bearing damage, etc. Security risks

However, these potential safety hazards are not easy to be directly noticed by operators or maintenance personnel. Over time, they will eventually lead to abnormal flight of unmanned aerial vehicles, major accidents or even extreme situations such as bombings.
