复杂遮挡环境下水闸变形监测数据处理方法
Data processing method for sluice deformation monitoring in complex occlusion environments
摘要
Abstract
Based on the severe impact of multipath effects on the deformation monitoring of water gates in complex occlusion environments,as well as the slow displacement characteristics caused by the influence of upstream and downstream water levels and seasonal temperatures,a random model with carrier to noise ratio constraints,robust observation values with slow displacement constraints,and a multi path correction method with a hemispherical model were used to obtain the dynamic time series coordinate sequence solution results.The dynamic time series results were refined by extracting time period displacement based on smooth prior analysis,obtain the time interval solution,used for real time and continuous long term monitoring of deformation and displacement of water gates.To verify the effectiveness of the above methods,deformation monitoring in a complex environment with semi occlusion of the sluice was verified through experimental design.The results show that this method can eventually achieve high-precision water gate displacement monitoring with an accuracy of approximately 1 mm.关键词
