隨著無線射頻辨識技術(Radio Frequency Identification,簡稱為RFID)技術的應用層面越來越廣泛,而電子標籤品質是整個應用的關鍵。尤其在長距離的應用,讀取距離更是重點,所以製造商在生產電子標籤時,透過線上品檢確保電子標籤品質,避免不良品流入市面造成的客訴問題。一般RFID UHF 被動式電子標籤製造的生產機台,在線上品檢所採用的技術是以近場讀取讀取電子標籤序號的有無,用以作為電子標籤的好壞依據,並依據量測結果作為生產品質之良莠,但此方式無法得知電子標籤實際運作時的狀況。 為了克服線上品檢空間與檢測速度上的限制,本研究提出一套創新式UHF 電子標籤測試方法。這套方法是以衰減器縮短量測距離,運用EPC global 靜態測試法,找出發射端到接收端間的能量差異,透過本研究提出之轉換方式,即可得知穩定讀取距離。為了驗證本研究所提之方法,與傳統電子標籤性能測試方式進行結果比較,確認本研究方法的準確度及精確度;此外,本研究說明了如何將此套測試方法的概念,實際應用於電子標籤分級,以突顯本研究所提出之方法的實用價值而本研究的方式除了可以協助業者進行線上之即時檢測,並在電子標籤製造時進行產品分級,以降低不良品的客訴及提升產品應用良率。
The general manufacturing production machine of UHF passive RFID, the technology of online inspection is used in near field to read the serial number tag successfully or not in order to measure that the electronic tag is good or bad and to determine high and low production quality, but it cannot show further tag performance. This study research provides a short distance performance testing method by using passive tag and use the EPCglobal static test method to measure the turn on power, and test received signal strength indication in this condition. By the transfer method proposed in this study can get the longest steady reading distance; this method not only can help business owners to process the real-time online quality inspection, but also can grad in product manufacturing to reduce customer complaints and enhance product applications .
