为了研究监测对象的变形规律,有必要消除测量噪声得到更准确的数据,小波变换理论在数据处理方面有其特点。本文利用小波去噪的理论对监测数据进行小波变换,得到信号的高频部分,并进行去噪处理,得到了较好的效果。此方法具有一定的工程应用价值,本文提供了一个地铁工程变形监测数据处理的例子。
In order to study the deformation law of the monitoring object, it is necessary to eliminate the measurement noise and get more accurate data. The wavelet transform theory has its own characteristics in data processing. In this paper, the theory of wavelet denoising is used to carry out wavelet transform on the monitoring data to obtain the high frequency part of the signal, and the denoising processing is carried out. The good effect is obtained. This method has a certain value of engineering application, this article provides an example of subway deformation monitoring data processing.
