摘要

本研究利用無線感測網路多點跳躍的特性，建立地滑地監測系統。首先研發銜接感測器與無線感測網路節點之訊號放大器，再透過無線感測器網路將多站之量測電壓訊號回傳至中繼站；中繼站採用嵌入式系統進行資料之暫存後，透過整體封包無線電服務將訊號即時回傳至控制中心；回傳之電壓訊號透過轉換公式可以得到即時感測資料，這些資料包括降雨量、地下水位、岩錨之荷重、擋土牆之鋼筋彎矩等，再透過網頁及資料庫建立，提供使用者之即時查詢。本系統實際安裝於霧社水庫下游之地滑地，透過太陽能建立自給自足之供電系統，經長期驗證後證實可以穩定使用，未來可進一步應用於相關環境監測。

This study used the multi-hop topology of wireless sensor network (WSN) to construct a real-time monitoring system of landslide. The amplifier is developed to build the connection between sensors and WSN, which is then used to transmit the sensor data to gateway by the format of electric voltage. The gateway, which adopts the embedded system as the control system, temporally storages sensor data and transmits them to internet server by using General packet radio service (GPRS). The sensor data is then obtained by the transport equation between electric voltage of sensor and physical data, which may include rainfall depth, groundwater level, load cell and momentum of rebar. The website and database is also built to supply the requirement of real-time query. This system is installed in the landslide located in the downstream of Wu-She dam. The solar cell is used to provide the enough power. After a long term verification, this system is still stable, so as to apply in the environmental monitoring of hillslope.
