变形监测数据降噪分析

Noise Reduction Analysis of Deformation Monitoring Data

在分析变形情况相对小的监测过程中,因监测数据本身会受到噪声影响,变形趋势表现将会出现模糊,无显著特征,产生震荡等,不符合实际情况,对数据分析及趋势预测等方面也会造成困难。某水电站滑坡体监测阶段,通过小波的方式去噪也将会对监测数据采取有效预处理。综合数据拟合及相关数据分析,发现与实测数据之间进行比较分析结果更优。

In the analysis of relatively small deformation monitoring process, because the monitoring data itself will be affected by noise, the deformation trend will appear fuzzy, no significant features, resulting in shocks, etc., not in line with the actual situation, the data analysis and trend forecast, etc. will form difficulties. Some hydropower station landslide monitoring stage, by way of wavelet denoising will also take effective pretreatment of monitoring data. Comprehensive data fitting and related data analysis, found and measured data between the comparative analysis of better results.
