Problems solved by technology

[0002] At present, the inclination measurement of towers mainly relies on manual total station measurement or measurement by installing angle sensors, but there are certain problems in the continuous measurement of inclination, especially for towers located on hillsides.
When the wind speed reaches a certain level, due to the wind dance effect of the guide on both sides of the tower, the tower itself will swing to a certain extent, especially for the 220KV tower, the height of the tower is high, the wind swing is large, and the simple measurement angle cannot obtain a stable value. Prone to early warning false positives, missed negatives

Abstract

The invention discloses a vibration-bended data processing method for pole and tower inclination angle measurement. The data processing method comprises the steps that firstly, vibration displacement data are processed; secondly, inclination angle data are processed; thirdly, displacement data are synchronized; fourthly, a difference value sequence between two sequences is obtained through Dis calculation. The data processing method has the advantages that an accurate pole and tower inclination angle is obtained by continuously measuring pole and tower vibration and pole and tower inclination angles and blending data of pole and tower vibration and the pole and tower inclination angles, and the whole algorithm is accurate, high in practicability and good in using effect.

Description

technical field [0001] The invention relates to a data processing method, in particular to a data processing method for measuring the inclination angle of a tower combined with vibration. Background technique [0002] At present, the inclination measurement of towers mainly relies on manual total station measurement or measurement by installing angle sensors, but there are certain problems in the continuous measurement of inclination, especially for towers located on hillsides. When the wind speed reaches a certain level, due to the wind dance effect of the guide on both sides of the tower, the tower itself will swing to a certain extent, especially for the 220KV tower, the height of the tower is high, the wind swing is large, and the simple measurement angle cannot obtain a stable value. False alarms and missed alarms are prone to occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a data processing method f...
