為減低相對主觀且耗時費力的目測評估方法，本研究藉由加速度計、微型處理器與NB-IoT取得現地資料，並根據所取得之加速度值重建為位移值，作為基礎設施初步安全評估的指標。所提出的重建位移主要係利用最佳化方法求取相關參數，經縮尺寸試驗驗證準確性後，應用於現地取得防砂壩位移資訊，提供主管單位管理維護之參考。

To reduce the subjective and time-consuming visual inspection, this study acquired in-situ accelerations by utilizing accelerometers, microprocessor and NB-IoT, in which the obtained accelerations are converted into displacement based on the proposed reference-free displacement reconstruction method. The reconstructed displacement can be served as the preliminary safety indicator of infrastructures. The proposed reference-free displacement reconstruction is mainly accomplished by optimization. After verifying the accuracy through numerical and down scale experiments, the device implemented with the proposed algorithm are used to obtain the displacement information of the selected checked dam to collect the displacement and provide a reference for the management and maintenance of the government agency.
