Abstract

The invention belongs to the technical field of wind power equipment detection and relates to an autonomous unmanned aerial vehicle fan blade polling system and method. The autonomous unmanned aerial vehicle fan blade polling system comprises an unmanned aerial vehicle used for carrying out automatic polling on fan blades, a polling vehicle used for stopping and placing the unmanned aerial vehicle, a ground station used for receiving and processing image data sent by the unmanned aerial vehicle to control the unmanned aerial vehicle and a specialist terminal used for judging and analyzing the image data of the ground station. The autonomous unmanned aerial vehicle fan blade polling method comprises the following steps: starting polling; positioning; finding a fan nose by the unmanned aerial vehicle after taking off; processing image data, and judging whether the fan nose is found or not; starting an automatic polling mode; shooting fan blades by the unmanned aerial vehicle flying along the edges of the fan blades, and transmitting blade image data to the ground station; determining whether the fan blades are in fault or not by a maintainer, transmitting the fan blades which can not be determined to the specialist terminal, and judging and analyzing by the specialist terminal; and finishing the polling. The autonomous unmanned aerial vehicle fan blade polling system and method have the advantages that on-the-spot control of the maintainer is not required, a vehicle collision accident can be avoided, manpower resource is saved and popularization and application are easy.

Description

Technical field

[0001] The invention belongs to the technical field of wind power equipment detection, and relates to a fault inspection system and method for wind power fan blades, in particular to an autonomous drone inspection fan blade system and method. Background technique

[0002] In the prior art, in the technical field of maintenance of wind turbine blades in wind farms, there are mainly the following three maintenance methods:

[0003] The first type: do not do any daily maintenance, repair afterwards;

[0004] This kind of operation mode is common in wind farms with relatively backward management in China. Due to lack of equipment and methods and no professional maintenance personnel, this type of wind farm does not conduct inspections on the wind turbine blades, and take corresponding measures after the obvious failure of the blades has caused the attention of maintenance personnel. Maintenance measures. There are obvious problems with this kind of method. One is the hi...
