Problems solved by technology

[0003] At present, the measurement of the inclination of the tower base ring usually requires the surveyors to carry professional equipment to carry out multiple optical point measurements on the bottom of the tower for a week. In this process, the positions and readings of the points are all manually involved, and there are large problems. measurement error, and poor real-time performance

Abstract

The invention relates to a method, device, system and storage medium for measuring the inclination of the foundation ring of a wind turbine tower. Marker feature set at each moment; respectively according to each marker feature set fitting to obtain the optimal tower tilt plane of the tower to be tested at each moment; according to the marker feature extraction model and each moment The optimal tower inclination plane is used to obtain the inclination index set of the tower to be tested at each moment respectively. The invention can automatically identify the characteristics of markers through modeling, evaluate and measure the inclination degree of the foundation ring of the tower tube in real time from multiple indicators, without manual participation, high measurement accuracy, and more comprehensively, accurately and real-timely describe the tower tube Tilt situation.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, a system and a storage medium for measuring the inclination of a fan tower base ring. Background technique [0002] Due to the influence of wind speed and terrain, during the actual operation of the wind turbine, the gap between the foundation ring of the tower and the concrete is likely to cause the fan to shake. The shaking of the unit for a long time will cause a certain inclination of the foundation ring of the tower tube relative to the horizontal plane; at the same time, due to poor foundation grouting and weak connection of the base, the stiffness distribution of the unit base will also be uneven, resulting in the appearance of the foundation ring of the tower tube. Inclination; and the inclination of the tower will in turn aggravate the shaking of the wind turbine. The long-term operation of the fan with shaking will have a great impact on the large comp...
