摘要
目前在海道测量中,潮位数据一般使用压力式验潮仪自动采集。自动验潮仪RBR数据采集频率高,精度高,体积小,能方便的安装于各种物体上,广泛应用于海洋研究、港口堤坝监测和海道测量等方面。本文就压力式自动验潮仪在潮位观测数据处理中的相关问题进行研究,同时给出了气压改正方法,阐述了验潮仪RBR的零点漂移问题,探讨了利用小波分析的方法进行潮位观测数据平滑去噪的可行性,并介绍了去噪的方法和步骤。
At present, in the hydrographic surveying, tide data are commonly collected by using RBR automatic pressure tide gauge that is of high frequency collecting, high precision, small volume and convenient installation in various objects. It is widely applied in marine research and monitoring of port and dam as well as hydrographic measurement. This paper researches on the problems that occur in the tide data processing of automatic pressure tide gauge. Meanwhile, pressure correction is put forward. It also describes the zero drift correction of RBR tide gauge and discusses the feasibility of smoothing and de-noising the tide data by wavelet analysis method. Finally, the de-noising methods and steps are introduced.
