基于GPS卫星测量的远距离滑坡监测应用研究

利用GPS进行远距监控滑坡区并做适用性的评估研究,整合系统中含供电系统(室内及室外电源设置)、无线传输(利用GSM传输)、GPS资料后处理软件及监控软件等。所组合的系统将应用在某滑坡区,进行长时间持续监测。试验方式包含现场模拟试验、滑坡模拟测试,同时以远近两不同距离的主控站来评估此监测系统因基线长短不同所造成的精度影响,以期能通过此研究提出GPS监测系统设置的经验。根据研究成果指出,GPS监测系统应用在滑坡监测上可行,利用无线传输(GSM)可成功将现场的资料传给远程的操作者。试验结果显示,利用近基站观测可提高观测的精度及解算的成功率,但不论在远基线或近基线的试验,GPS监测系统的精度均可达到公分等级。

The application research of landslide monitoring with GPS satellite survey

For the GPS surveying and positioning systems have had much better reliability and efficiency recently,people are trying to integrate the wireless communication and GPS units to reset a brand-new remote monitoring system.People can also get some advantages from the characteristics of GPS,such as automatic receiving,24hours detecting,high precision data collecting.So,in the low dynamic landslide area,GPS remote monitoring system can be used in detecting the variation of changing in this area.In this research,we integrate the power supply system(out-door and in-door systems),GSM cellular with SMS protocol,post-processing software,and monitoring software to reset a remote monitoring module.Tests include local simulating experiment and landslide simulating experiment.Two different type of baseline from the monitoring area to the reference sites will be considered,and we are trying to figure out the difference of accuracy between the short-distance and long-distance baselines.The results and experiences of those experiments can be used as reference for the monitoring baseline setting-up work.The results show that it is feasible to use GPS monitoring system for landslide monitoring.The data is conveyed successfully for the operator by using the wireless communication(GSM),and using the short baseline length can promote the precision of surveying and the calculating with both.According to the experiments,the accuracy of GPS monitoring system can also reach to centimeter degree either the short-distance baseline or the long-distance baseline.
