Application of Kalman Filter in Deformation Monitoring for Tailing Dam by GPS

为更好地提高尾矿坝变形监测精度、节约工程成本,将Kalman滤波技术和GPS一机多天线相结合,解决了卫星跟踪和抗干扰问题。在介绍GPS在水电大坝和尾矿坝具体应用情况的基础上,通过Kalman滤波在GPS中的应用数据分析,说明采用kalman滤波方法处理的GPS监测数据可显著提高数据精度。由于Kalman滤波技术实时更新,因此更适用于在线分析,对监测信息化具有重要意义,可以在水利工程监测中推广应用。

For the sake of increasing deformation monitoring precision for tailing dam and reducing engineering cost, Kalman filter technology and GPS with multi-antennas are used to solve problems of satellite tracking and antiinterference. Based on describing application of the GPS in hydropower dam and tailing dam, data analysis on Kalman filter used in GPS shows that GPS monitoring data processed by Kalman filter can greatly raise data precision. Because Kalman filter possesses good performance of real-time updating, it is more suitable for on-line analysis and has great important meanings in monitoring informatization and it can be promoted to be used in monitoring for water resources project.
