Method and system for recapturing lost blade tips of draught fan during tracking and detection of blade tips through drone

Abstract

The invention provides a method and system for recapturing lost blade tips of a draught fan during tracking and detection of the blade tips through a drone. The draught fan comprises a wind tower, animpeller and a power generator, wherein the impeller and the power generator are disposed on the top of the wind tower; the impeller includes a wheel hub connected with the power generator and multiple blades uniformly distributed along the circumference of the wheel hub, and one blade is adopted as a target blade. The method includes the following steps of controlling a flight of the drone from one side face of the target blade from a blade tip region to a blade root region and using a solid-state radar arranged on the drone for detecting the target blade; when the solid radar detects the target blade, determining the position of a flight path when the distance between the drone and the target blade is controlled to be greater than or equal to first set distance; controlling the drone tofly from the position of the flight path to the blade tip region and then fly from the blade tip region to the blade root region, and using the solid-state radar arranged on the drone for tracking anddetecting the target blade at the same time. The method and system solve the problem of the loss of blade tip regions, and comprehensive photographing and detection of the blade tip regions are achieved.

Description

technical field [0001] The present invention relates to fan detection, in particular to a method and system for tracking and recapturing fan tip tracking and detection by an unmanned aerial vehicle. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. Wind turbines generally consist of components such as blades, generators, steering devices, towers, speed limiting safety mechanisms, and energy storage devices. [0003] During the long-term operation of the wind turbine, the surface of the blade will show various damages, such as damage to the protective film of the blade, peeling of the paint on the blade, freezing of the blade, cracks on the blade, and oil pollution on the blade. [0004] At present, when detecting damage on the surface of the blade, it is usually used to manually climb up the wind turbine for detection, which not only consum...

AI Technical Summary

Problems solved by technology

In order to improve the detection efficiency of the UAV, it is necessary to plan the flight route of the UAV, but when completing the progress on one side of the blade, it is necessary to go around to the other side of the blade through the tip of the blade, and in the area of ​​the tip of the blade, the The width is narrow, and the field of view of the solid-state radar is fixed. At this time, the blade is often not detected, resulting in insufficient comprehensive detection of the blade tip area or even missed detection.
