自動化雷射掃描量測設備開發

本研究主要之目的為應用三角雷射探頭，搭配三軸方向移動平台之量測系統進行各種量測，將其程式化並且應用處理各種量測數據上之即時分析統計。本論文中使用此架構設計一系統整合程式：針對散射式或反射式三角雷射探頭進行非接觸式量測，將擷取的訊號經由RS-232傳輸至電腦，並利用RS-485控制三軸平台，以進行大範圍量測，將雷試探頭擷取到的資料形成一3D表面。本研究使用視覺化程式設計語言概念，建構出一套光學量測應用程式。首先將訊號藉由RS-232/RS-485傳輸至電腦，然後在圖形介面下即時儲存記錄這些訊號。本程式設計概念將各類訊息分析，並做適當顯示圖表與資料處理，達到提供使用者親切的圖形介面，以及監測資料處理狀態，並且以圖形化概念判斷目前數據是否正常之最佳依據。本研究所發展的量測系統，主要功能可以量測厚度、進行SPC統計製程管制、表面平整度分析、趨勢線分析計算等各種統計分析，並且可以迅速產生一份報告結果並列印。本研究成功應用於量測各種高度以及表面，並且有效進行線上數據分析處理，並設計出人機介面以利使用者操作。

This study used triangular laser probe and three-axial direction mobile platform for surface measurement, programmed it and applied it to real-time analytic statistics of different measured data. This structure was used to design a system integration program: use triangular laser probe for scattering or reflection non-contact measurement, transfer the captured signals to the computer through RS-232, and use RS-485 to control the three-axis platform for a wide range of measurement. The data captured by the laser probe are formed into a 3D surface. This study constructed an optical measurement application program in the concept of visual programming language. First, the signals are transmitted to the computer through RS-232/RS-485, and then the signals are stored and recorded in graphic interface timely. This programming concept analyzes various messages, and makes proper presentation graphs and data processing to provide the users with friendly graphic interfaces and data processing state monitoring, and identifies whether the present data are normal in graphic concept. The major functions of the measurement system developed by this study are thickness measurement, SPC, surface smoothness analysis, and analytical calculation of trend line. A result report can be made and printed promptly. This study measured different heights and surfaces successfully, performed on-line data analysis and processing effectively, and developed a man-machine interface for users to operate.
