Problems solved by technology

However, after the data is measured, it is necessary to manually input the data into the UAV control device, and then manually or automatically control the UAV to rise from the ground to the height of the wind turbine, and then start the blade detection, which makes the inspection process complicated.

Embodiment

[0047] Such as figure 1 As shown, a method for measuring the height of a wind turbine of the present invention comprises the following steps:

[0048] The first step is to construct the reference point cloud data for detecting wind turbines and preset the height value of the wind turbine model. Specifically, it is generally constructed based on the shape data of the wind turbine provided by the wind turbine manufacturer, and the center point at the bottom of the tower 4 is selected as the origin to establish a coordinate system with an interval of 10 cm. The reference point cloud data can accurately correspond to the actual structure of the wind turbine. The height value of the preset wind turbine model is established based on the shape data of the wind turbine. According to the actual parameters of the current wind turbine, the value can generally be set between 70-150m, so as to cover more types of wind turbines.

[0049] In the second step, the UAV is placed in the take-o...

Abstract

The invention discloses a height measurement method for a wind turbine generator. The method comprises the following steps that Step 1, reference point cloud data for detecting the wind turbine generator are constructed according to initial shape data of the wind turbine generator, and a height value of a wind turbine generator model is preset; Step 2, an unmanned aerial vehicle vertically takes off and ascends, and a laser radar on the unmanned aerial vehicle scans the wind turbine generator in the ascending process to obtain point cloud data; Step 3, a coordinate system is established by taking the center point of the bottom of a tower drum of the wind turbine generator as an original point, and ICP matching calculation is performed on the reference point cloud data in the step 1 and the point cloud data in the step 2 to obtain a matching degree value; and Step 4, the matching degree value obtained in the step 3 is compared with a preset matching degree threshold value, and when the matching degree value is greater than or equal to the matching degree threshold value, the vertical direction height of the point cloud data in the step 2 corresponding to the matching degree value is used as the actual height of the wind turbine generator to obtain the height value of the wind turbine generator. The accurate height of the wind turbine generator can be rapidly measured and obtained.

Description

technical field [0001] The invention belongs to the field of detection technology of wind turbines, in particular to a method for measuring the height of wind turbines. 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 are generally composed of a cabin (transmission mechanism and generator), blades, towers and other components. [0003] During the operation of wind turbines, the surface of the blades will show various damages, such as paint peeling, blade freezing, cracking, lightning strikes, etc. At present, the traditional wind turbine blade inspection usually uses manual climbing on the wind turbine and high-altitude operations for inspection, which not only consumes a lot of manpower, but also has great potential safety hazards. [0004] Therefore, the detection of wind turbine blades by carrying image acquisition device...
