Abstract

The invention discloses a fault detection method and device for an unmanned aerial vehicle. The method comprises the following steps of judging whether the flight mode of the unmanned aerial vehicle is a fixed-height mode or not, if the judgment result indicates to be yes and the numerical value of the GPS height lower than the first target height is greater than a first threshold value, determining the cause of the fault of the unmanned aerial vehicle based on the GPS vertical speed, and if the judgment result indicates to be no, determining change information of the simulated terrain height in a first preset time period, and determining the cause of the fault of the unmanned aerial vehicle based on the change information. The technical problems of long time consumption and low efficiency caused by manually analyzing the fault cause of the unmanned aerial vehicle according to the flight log in the prior art are solved.

Description

technical field [0001] The present application relates to the field of intelligent control, in particular, to a fault detection method and device for an unmanned aerial vehicle. Background technique [0002] In the prior art, when a UAV has a flight failure, the guarantee form submitted by the customer includes the flight log and the photos of the bombing environment. For most of the flight failures, only the flight log is needed to determine the cause of the bombing. Flight failures also need to be identified in combination with environmental photos of the bomber and manual explanations. [0003] In the past, the analysis method of UAV flight accidents was to manually analyze the data of the flight log through the software and make a judgment in combination with the photos and descriptions of the bombing environment. , in the busy season, there are often 70 to 80 or nearly hundreds of flight accident data a day that need to be manually analyzed and processed. Causes of ma...
