儀表組檢測系統開發

近年來，車用儀表朝具CAN Bus通訊功能整合性儀表組方向發展。在現今大量生產的情形下，伴隨著儀表組進料和組裝上的過程，需要耗費大量人力進行檢測，以確保生產品質；為節省人力，並改善人工檢測誤差，需要開發一套簡易的儀表組檢測系統。本文使用Visual C++ MFC視窗介面軟體，開發儀表組視覺檢測系統；並使用Open CV影像處理軟體，進行儀表視覺影像辨識技術開發，包括指針角度辨識、燈號顯示等。此外，為因應各型號儀表組不同檢測需求，需建立檢測數據資料庫，以產生儀表組檢測所需之頻率、電壓、電阻或數位I/O訊號，並可儲存及列印檢測資料報表。另配合不同檢測需求，能做各種儀表組的教導學習及參數設定等，以使檢測系統具有通用性檢測功能。經實際操作測試結果顯示，使用本文開發的車用儀表組檢測系統，協助進行儀表組自動檢測，可以有效的提昇檢測效率，並減少人工檢測的誤差，提高檢測品質，值得業者加以採用。

Recent years, vehicle cluster integration with CAN-bus communication. Mass production case of feeding and assembling that need manpower testing to ensure product quality. Therefore, develop a simple vehicle cluster testing system to reduce error of manual testing and waste of manpower. This article describes design of vehicle cluster testing system that using windows interface software of visual C++ MFC. Development vehicle cluster visual Image detection technology that using image processing software by OpenCV, to identification of pointer angle and light display. In addition, create a database of test data to generate frequency, voltage, resistance, I/O signal. To provide test different vehicle cluster. This system can save, print test data report. The system has universal detection with different testing needs, self learning and teaching about parameter setting. The test results show using this system to assist in automatic detection can improve detection efficiency, reduce error of manual testing, and improve the detection quality .This system worth companies to use.
