| 摘 要： | GPS变形监测系统中的监测点的观测资料是与时间有关的信号序列,本文研究应用小波分析优化流程,结合苏通大桥GPS变形监测系统获取的监测点数据序列进行分析。结果表明,选择合适的小波基函数,对数据信号进行小波分解与重构,可以有效地从受到强噪声干扰的监测数据序列中提取有用的特征信号,较好解决了传统处理技术对GPS动态观测数据去噪以及特征信息提取的局限性。

| Abstract: | The observation material of monitoring points in GPS deformation monitoring system is the time-related signal sequence.It is the analysis of data sequence of monitoring points obtained from Sutong bridge GPS deformation monitoring system using wavelet analysis optimization processes in the paper.The results showed that choosing the appropriate wavelet basis function,wavelet decomposition and reconstruction of the data signals could effectively extract useful signals of features from the monitoring data sequence interfered by strong noise,which would help solve the limitations of traditional solving technology in de-noising GPS dynamic observation data and extraction of feature information. |
