A method and system for online monitoring of transmission tower

Abstract

The invention relates to the technical field of safety monitoring of power transmission towers, and in particular to an online monitoring method and system for power transmission towers. The method comprises: fitting power transmission tower data to obtain stress data-time curves and stress data-height curves respectively, calculating the noise performance degree and the credibility of the stress data points, performing weighted averaging on the noise performance degree and the credibility of the stress data points of the target data sequence to obtain the noise level of the target data sequence, accurately evaluating the denoising result of a CEEMDAN algorithm by using the noise level, obtaining the optimal average number of times of the CEEMDAN algorithm according to the feedback of the evaluation result, avoiding the limitation of manually setting parameters, ensuring the data denoising effect, obtaining stress data that truly reflects the stress state of the power transmission tower, and improving the accuracy of monitoring and analysis of the power transmission tower.
