摘要

隨著全球衛星定位系統GPS定位技術成熟及精度提升，整合無線通訊設備元件之遠端監測系統變為可行。GPS具有主動接收、全天候觀測及高精度等特性，對於潛變之區域可透過遠距離連續接收
進行監測。

本研究擬利用GPS進行遠距監控地滑區並做適用性之評估研究，整合系統中含供電系統（室內及室外電源設置）、無線傳輸(利用GSM傳輸)、GPS資料後處理軟體及監控軟體等。所組合之系統將應用於宜蘭縣五峰旗赤皮嶺地滑區，進行長時間持續監測。實驗方式包含靜態模擬試驗、現地模擬試驗、模擬地滑測試，同時並以遠近兩不同距離之主控制站，評估此監測系統因基線長短不同所造成之
精度影響，期能透過此研究提出GPS監測系統設置之經驗。

根據研究成果指出，GPS監測系統應用於地滑監測上實為可行，利用無線傳輸(GSM)可成功將現地的資料傳給遠端的操作者。實驗結果顯示，利用近基站觀測可提升觀測的精度及解算的成功率，但不論在遠、近基線的實驗上，由本研究結果得知GPS監測系統的精度
可達到公分等級。

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 integrated 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, and we were processing the evaluation of feasibility in this module. The integrated module was tested many times in the landslide area, WuFongChi, Ilan, Taiwan, which were getting low dynamic slide, and the monitoring test will be continued. Tests included static simulation experiment, 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.
According to the results of this study, 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.
