本論文針對高度量測,提出一種低成本、高實用性、易操作的複合式量測儀器,主要是建築工程中經常使用到的水平、距離、高度量測相關儀器做進一步的整合,有鑑於建築用儀器大多昂貴且功能單調,因此本論文系統結合雷射模組、超音波感測器、慣性感測器與微電腦控制器,並利用Solid Works進行機構設計,製作出一種可量測距離、水平並以非接觸的方式量測高度的多功能建築量測儀器。本系統在微電腦控制器中加入三角函數的正切定理進行高度演算,經由實驗驗證,本系統可運用感測器取得高度量測的相關係數,透過三角函數的正切定理進行物體高度量測的功能,使其在微電腦控制器上實現非接觸高度量測功能,並透過Measurement System Analysis中GR&R量測分析法進行裝置驗證。
This study presents a low-cost, extremely practical and easy-to-operate composite instrument for measuring height. This instrument uses the level, distance, and height measurement devices typically employed in construction works for further integration. Because most instruments used in construction and architecture are expensive and have only single functions, the system developed in this study combines laser modules, ultrasonic sensors, inertial sensors, and a HT46R232 microcontroller. We also used Solid Works to design a multifunction construction measuring device that can measure distances and levels and uses a non-contact method to measure height. This system adds the tangent theorem of trigonometric functions to the microcomputer controller for height calculation. Experimental verification indicated that this system can use sensors to obtain correlation coefficients for measuring height. The tangent theorem of trigonometric functions was used to measure object height. This facilitated non-contact height measurements in the microcomputer controller. Measurement system analysis (MSA) was employed to verify that the measurement system adheres to the QS9000 measurement system specifications.
