Problems solved by technology

[0004] However, the above two methods have the following disadvantages: firstly, the first method is more dangerous, and the detection effect is poor, and it is difficult to meet the needs of fast and accurate inspection of blades; secondly, in the second method, the drone When inspecting fan blades, the UAV only monitors the condition of the fan blades during the flight of the preset route, and the accuracy of the collected fan blade image data is not high enough, which causes a waste of UAV operating costs

Embodiment 1

[0016] figure 1 The method flow chart of the embodiment of the method for detecting the state of fan blades by unmanned aerial vehicles provided by the present invention, such as figure 1 As shown, the methods for detecting the status of wind turbine blades by drones include:

[0017] Step 110: Receive the first set of images of the wind turbine blades captured by the UAV flying along the preset route.

[0018] In a specific implementation manner, when planning the preset route of the UAV, the preset route may be decomposed into many points in space, and each point in space has its own spatial coordinates. Here, spatial coordinates may include, but are not limited to, longitude, latitude, and elevation. The UAV flies in the wind farm according to the preset route, and takes the first set of images of the fan blades in the wind farm, so that the images of the fan blades sent back by the UAV can be received in real time , these images can be stored in the form of photos and / o...

Abstract

The embodiment of the invention provides a method, an apparatus and a system for detecting the state of a blower blade through an unmanned plane. The method comprises the following steps: receiving the first image group of the blower blade, shot in the process of flight along a preset course, from the unmanned plane; analyzing the first image group to obtain the spatial coordinate when the first image group is shot; generating a control signal for starting the unmanned plane to shoot again according to the spatial coordinate, and sending the control signal to the unmanned plane; receiving the second image group of the blower blade from the unmanned plane; and analyzing the second image group to generate the analysis report of the state data of the blower blade. The method, the apparatus and the system for detecting the state of the blower blade through the unmanned plane realize blower blade state detection through using the unmanned plane, improve the detection accuracy and efficiency, and save the operation service cost of the unmanned plane.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a method, device and system for detecting the state of fan blades by means of an unmanned aerial vehicle. Background technique [0002] The blades of wind turbines (hereinafter referred to as fans) are the key components that convert wind energy into mechanical energy. During the long-term operation of wind turbines, the surface of the blades will show various states such as blade dents, blade paint, and blade scratches. scratches, blade icing, blade cracks, and blade contamination. If these conditions are not discovered and repaired in time, accelerated aging will occur, which will affect the service life of the blades. [0003] The current blade state detection methods mainly include the following two methods: one is to use spiders, hanging baskets, and high-powered telescopes; the other is to use drones to install video acquisition devices to monitor in real time and grasp...
