Abstract (in Chinese)
本研究目的為利用自動化對於高重複性的這項優點並參考英業達集團PD (Power Delivery)團隊檢測問題時的需求,擷取包括CC(Configuration Channel)、I²C(Inter-Integrated Circuit)、Aux(Auxiliary)等訊號用以複製工廠檢測後發生的問題,進而開發出自動化控制系統,能有效節省測試時的人力與時間成本,對擷取USB-C傳輸介面訊號進行比較,從而幫助使用者藉由擷取到的訊號進一步判別其測試結果並設法解決。
    本研究利用C#程式語言搭配WPF(Windows Presentation Foundation)專案進行自動化UI (User Interface)的開發,以主從式架構區分客戶端與伺服器,結合Sniffer、Saleae、Aux Decoder board等治具搭配”EZ-PD Protocol Analyzer”、”Saleae Logic”、”AuxMonitor”等外部程式進行訊號擷取;在機電控制方面,插拔USB-C與敲擊電源鍵則利用Arduino MEGA 2560控制單軸可攜式機械手臂完成自動化測試。
    本研究實現了依靠自動化系統完成各項訊號的擷取,檢測實驗目標是否發生錯誤,並將所有數據紀錄並分別存放,利於實驗結束後測試人員查看實驗結果,進一步判斷異常原因著手解決,建立全自動化測試流程與判斷方式。
Abstract (in English)
An automation system has advantages of high repeatability and reliability. This study aims to develop a special automation detection system to extract the signals, i.e. CC(Configuration Channel), I²C(Inter-Integrated Circuit), Aux(Auxiliary), etc., of the USB-C interface, thus saving time and cost. The system is developed according to the need of the PD(Power Delivery) teams in Inventec, such as detection procedure and workers’ experience.
    This study uses C# programming language and WPF(Windows Presentation Foundation) project to develop an automated UI (User Interface). The used external libraries to extract signals for this project are Sniffer, Saleae, Aux Decoder board with "EZ-PD Protocol Analyzer", "Saleae Logic", and "AuxMonitor". In addition, the motion of plugging/unplugging USB-C and hitting the power button is controlled by the Arduino MEGA 2560 to complete the automated test.
    This study realizes the automation detection system to complete the procedure of extracting signals, detecting whether the experimental target error, and storing all the detected data. The testers can check the experimental results after the experiment and further determine the cause of the abnormality and find the solution. The automation detection system establishes a fully automatic test process and judgment method.
