RTK技术在滑坡监测中的应用及系统设计

Application of RTK Technology in Landslide Monitoring and System Design

针对目前滑坡位移监测中的难点以及野外应用的要求,综合比较各类滑坡位移监测方法和现有的监测系统,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。利用安置在滑坡监测现场的两台低价位GPS接收机,将检测到的原始数据通过无线网络传输至监控中心,然后在计算机上作差分解算,实时计算出基线长度并显示其变化曲线。试验结果表明,系统测量精度能够满足滑坡监测的要求,且具有无人值守的优点。

Aiming at the difficulties in current landslide displacement monitoring and the requirement of field application, various landslide displacement monitoring methods and existing monitoring systems are compared comprehensively. Based on dynamic differential GPS algorithm, and combining with GPRS wireless transmission network, a low cost landslide displacement real-time monitoring system is designed. By using two of the low cost GPS receivers that installed at the monitoring site, the raw data detected are transferred to monitoring center via wireless network ; then the differential operation is done by computer to obtain the length of the baseline in real time and display the curve of variation. The test result shows that the measurement accuracy satisfies the requirement landslide monitoring, and the system features the advantage of unmanned operation.
