摘　　要：针对目前滑坡位移监测中的难点以及野外应用中的高度自动化、全天候、不受天气影响等要求,综合比较了各类滑坡位移监测方法和已有的监测系统,基于动态差分GPS算法,结合GPRS无线传输网络,设计了一种低成本的滑坡位移实时监测系统.将安置在滑坡监测现场的两台GPS接收机通过无线网络把观测到的原始数据传输至监控中心,然后在计算机上作差分解算,并实时显示出基线长度的变化曲线.实验结果表明该系统的测量精度能够满足滑坡位移监测的要求.Against the difficulty of current landslide displacement monitoring and the requirements of field application as high automatization and all-weather,by comprehensive comparison of several landslide displacement monitoring methods and existing monitoring system,a low-cost landslides displacement real-time monitoring system was designed based on real-time kinematic differential GPS algorithm and combined with GPRS wireless network.In this system,two GPS receivers were set down at the scene of landslide displacement which transmit ted the raw data to monitoring center through wireless network,and resolved the baseline on the computer in real time.Experimental results demonstrate that the precision of the system can meet the requirements of landslide displacement monitoring.
