摘要

目前生產車用空氣壓縮機之製造公司迫切地需求在其產品檢驗上能顯著地降低品檢逃脫率。因此，本研究發展PC-Based視覺輔助車胎打氣機自動化品檢作業系統，以提供廠商有效地降低品檢逃脫率，及後續的產品管理及瑕疪品追蹤。
本文詳細說明本研究已獲得的初步成果，這成果包括：光源設計問題之解決、打氣機定位機構之設計、LCD顯示器與打氣機壓力錶指針數值等影像輔助之判讀、作業系統之整合及影像處理技術、作業系統程式之撰寫、以及處理影像判讀及介面I/O之時序控制。
本研究課題中影像輔助判讀部分包括：車胎壓力達250KPa時之電流錶與計時器數值、過壓時打氣機安全閥全開之壓力錶與電流錶值、安全閥全關時之壓力錶值、以及車胎由過壓降至250KPa時錶壓力指針之誤差。此外本作業系統可讀取黏貼於打氣機上之條碼、並建立受檢品之記錄，本作業系統業經廠商實地線上測試、並已獲得証實確能有效地將不良品之逃脫率降至千分之一。

Presently, the manufacture companies which produce air compressors for vehicles urgently need the escaping rate of the produce quality control examination can diminish greatly. This research study is to develop a PC-based testing system for examining the quality of the air compressors using vision, to develop it to supply the way to reduce products examination escaping rate for companies, to manage their products, and to trace those products with flaws.
This study elaborates on our initial achievements through this research, including: the solution of light source problem, the design of tire pump detent mechanism, the interpreting of image assistance in LCD and the numerical analysis of tire pump pressure gauge, the integration of operating system and the process image technology, the programming of operating system, and the interpreting of image and the time control of interface IO.
The interpreting of image in this research text includes: the tire pressure number of reaching 250KPA, the exceeding number of the tire pump pressure gauge and the timekeeper’s relief valve standard-sized sheet, the fully close number of pressure gauge’s relief valve, and the inaccuracy of pressure gauge from the exceeding tire pressure to 250KPa. In addition, this operating system is able to read the bar code on the tire pump, and keep track of the examinate; moreover, after the companies test online on the spot, it has already been proved that the operating system can reduce the bad product escaping rate to 1/1,1000.
Keywords：the air compressor for vehicles, products examination escaping rate, product examination operating system of the vision auxiliary.
