建物傾斜為都會地區地下工程安全監測的重要項目，透過量測施工時周邊鄰房的傾斜，可知施工是否有危及鄰房之疑慮、可預警可能災害之發生、並進而事前進行補救措迤，以免除工程災害之發生。
本研究開發設計一個可用來做為量測建物傾斜之量測儀器原型，儀器主要採用三軸加速規為儀器的傾斜量測核心，配合高解析度之類比數位轉換器來量測加速規所輸出之訊號，並利用嵌入式控制器擷取其數位訊號並轉換成傾斜角度。在儀器開發方面，使用基本的電路設計概念，從儀器內部三軸加速規、類比數位轉換、以及電源轉換元件的選取、測試各元件的功能性，到儀器整體的電路設計與配置，以完成一傾斜量測儀器，均在文中有詳細介紹。
本研究中除完成開發基於三軸加速規之傾斜量測原型儀器外，並針對儀器原型提出一套自動化的校正流程，以校正儀器內部需要校正之參數值，使儀器可以準確地輸出量測之傾斜角度，此自動化程序並可應用於其它基於三軸加速規之量測儀器。
本研究並開發了一套傾斜儀器間相互驗證之自動化程序，此自動化程序可自動地將兩置於同一平面上之傾斜儀器進行不同程度之傾斜，並透過計算程序消除兩儀器間之安裝誤差，進而能比較確認兩儀器之量測是否相同。透過前述之程序，可證明本研究之原型儀器與市售之傾斜儀具有相同之準確度，且無論在電力消耗或是儀器之建置成本與監測成本上均優於市售之傾斜儀，並且十分適合與無線感測器網路結合以進行建物傾斜之量測

Building tilt is one of the key indicators in a field monitoring program when underground constructions are involved. By measuring building tilt, impact of construction activities on surrounding structures can be identified, and precautions can be taken before disaster strikes.
In this research, a tilt-measuring device is developed based on triaxial accelerometers. By integrating accelerometer, high-resolution analog-digital converter, and embedded controllers, tilt can be measured. In this thesis, the process of developing the tilt-measuring device through selecting, testing and integrating triaxial accelerometer, analog-digital converter and voltage-conversion components is thoroughly documented.
In additional to developing the prototype tilt-measuring device, an automated procedure on calibrating parameters of the developed device is proposed. By using the procedure, required parameters of the device can be obtained, and the calibrated device can output accurate tilt measurement. The procedure can also be applied to other devices based on triaxial accelerometers.
Finally, an automate validation procedure is developed to confirm whether two tilt-measuring devices have consistent tilt measurements. This procedure validates two tilt-measuring devices by varying inclinations of two devices installed on the same plane, and a calculation procedure is applied to eliminate errors associated with device installations. Through this procedure, it is confirmed the prototype device is as accurate as a commercial tilt-measuring device. Furthermore, the prototype device has advantages on construction cost, power consumption and long-term monitoring cost. The prototype is suitable to combine with wireless sensor network technology to measure building tilts.
