臺灣博碩士論文加值系統

以往傳統的監測方式，乃是由人員定時至現場觀看並記錄其監測項目，再將記錄的資料以人工的方式輸入於電腦上分析。然而此過程需要大量人力資源投入，且可能產生人為的錯誤、亦無法提供密集的監測頻率。而現代監測採用自動化、電子化系統以解決前述之問題，但電子化之量測儀器則容易受到環境溫度變化而影響其量測準確度。
本研究嘗試探討目前市面常用之MEMS傾斜計及高精度低溫飄之傾斜計進行儀器受到環境溫度變化時對其量測角度之變化，比對兩個儀器分別對溫度效應之影響程度，並探討傾斜計之監測精度。試驗結果顯示相對於MEMS無線傾斜計在經過移動平均值處理後仍大於台北捷運大地監測系統規範所訂結構物傾斜計警戒值4'來看，高精度低溫飄傾斜計對於溫度變化所造成的溫度飄移效應能控制在0.32'~ 0.58' 之間，可以有效提昇量測精度的準確性。

In the past, the traditional way of monitoring was to collect data on-site manually from time to time and to analyze the recorded data on the computer. However, this process requires a large amount of human resources, and may produce man-made error. Moreover, the process can not provide intensive monitoring frequency. The modern monitoring technique uses an automated, electronic system to solve the aforementioned problems, but the electronic instruments are susceptible to changes in ambient temperature leading to a measurement accuracy problem.
This study attempts to investigate how the temperature change affects the angle measurements of the MEMS tilt meter and high-precision low-temperature-drift tilt meter. A comparison between the results measured by these two instruments under consideration of the temperature effect was made. The test results show that the reading variation of MEMS tilt meter due to temperatue effect has exceeded the allowable geodetic warning threshold of 4’, established in the “Taipei MRT Geodetic Monitoring System for Structural Inclination Guidelines” even after moving average process. In contrast, the high-precision low-temperature-drift tilt meter provides the reading variation between 0.32 '~ 0.58' under temperature effect, which can effectively improve the measurement accuracy.
