A Platform for PC-Based Physics Experiments : Data Acquisition and Analysis
論文摘要:
| 本論文說明一個PC-Based的物理實驗系統，該系統透過感測器、資料擷取電路及個人電腦 |
| ，架構一套物理實驗的基本元件，並且經由虛擬化的硬體控制程式，使用者可以不需控制 |
| 硬體電路，就能擷取實驗數據、儲存為檔案，以利爾後彙整。 |
| 目前這個系統的實作已大致完成，而驗証的結果顯示由於資料擷取電路的準確性，透過這 |
| 個實驗架構擷取到的數據足供學生做歸納、分析用，並可透過軟體的層次展現出傳統實驗 |
| 方式所無法達到的功能。 |
| 本論文乃就此系統的硬體設計方式、軟體控制流程及系統的限制做一完整的說明，並以三 |
| 個物理實驗的實例展示本系統的效能，未來更將結合網際網路的特點，提供一個更有效率 |
| 的科學知識之學習環境，相信藉由此一實作可以帶來一個新的學習管道，進而幫助使用者 |
| 理解科學定律的實質意義。 |
| This thesis presents a PC-Based system for performing Physics experiments, including sensors, a data |
| acquisition circuit and a Windows program to control the circuit. With the help of the program, the |
| user can acquire and save data of experiments in disk files for further analysis without manipulating |
| the hardware circuit by hand. The results of several experiments showed that the data acquired are |
| very useful for deriving the formulae of the involved Physical phenomena, with the help of MATLAB. |
| This thesis explains the method of hardware design, software control process and system limits, |
| and demonstrates its functions with three examples of Physics experiments. In the future, when we |
| use the system with Internet, it would offer a better environment for students to study Science courses |
| with on-line classmates. In the environment, I believe the users can appreciate the meanings of Science |
| in a brand new way. |
