西龙池上水库GPS变形监测系统研究及实现

CORS Development for Xilongchi Dam Deformation Monitoring

    摘要
  • 摘要: 为了实现对西龙池上水库变形的连续、自动化监测,研制了GPS变形监测软件DDMS,建立了西龙池上水库连续运行监测系统。1a的运行表明,系统具有较高的稳定性,DDMS在观测数据无缺失的情况下,提供有效解的概率高于98%。该软件2h时段解在N、E、U方向的重复性分别为1.2mm、0.9mm、2.2mm,4h时段解算N、E、U方向的重复性为0.8mm、0.7mm、1.5mm。利用本文实现的GPS监测系统可进行高效率的实时、自动化、高精度大坝变形监测。

     

    Abstract: Dam deformation monitoring system(DDMS) which benefits from GNSS continuously operating reference system(CORS) is established.It consists of two reference stations and five monitoring stations.We design a star topology network architecture and TCP/IP protocol for real-time data stream transmission.A data processing software with the function of quality control,coordinates estimation and transformation,then accuracy evaluation and session time setting are realized.One-year operating results demonstrate that DDMS has higher stability.The probability of providing effective solutions is up to 98% without data loss,and 2-hour-session solution can achieve 1 mm,0.7 mm,1.7 mm at north-south,east-west and vertical component of station respectively.The accuracy can be improved to 0.8 mm,0.5 mm,1.4 mm respectively while the session time extends to four hour.It is concluded that the system can provide a technically advanced and cost-effective infrastructure for dam deformation monitoring analysis.
