本論文主要針對超高頻射頻辨識系統(UHF RFID)在於汽車環境下的應用及面臨的問題進行特性研究。RFID在車載系統上的應用,將再高速公路電子辨識收費;停車場進出管理系統;車牌管理與車體(零件)辨識防竊等應用方面,深具發展前瞻性及市場經濟規模。在上述應用中基於便利性與成本因素考量,採用被動式標籤(Passive Tag)置於汽車環境中(如:車體與車牌位置;為大型金屬環境之中,汽車玻璃內;處於半封閉金屬環境中),這些環境對於RFID系統傳輸特性具破壞性及干擾,進而將引響應用的範疇,本研究提出的解決方法將具備學術價值及符合實務應用需求,更具備提升、推廣RFID產業應用價值。 本研究期望藉由系統整合應用角度出發,透過模擬技術與量測分析並結合現行RFID產業技術應用,來深入探討並發掘問題、現象以及提出解決方案。進而發展出適用的產品(Tag)及技術整合解決方案,來達成RFID於汽車環境應用下的靜態讀取辨識及動態(高/中/低速)讀取辨識,增加RFID的應用範疇。
The main points of this thesis are to study the applications of the ultrahigh frequency (UHF) RFID in the motor vehicle conditions and solutions of the potential problems. The applications of RFID in the motor vehicle communication system are included Electronic Toll Collection (ETC), parking lot in and out management, vehicle identification number and body management to escape from stolen. These applications have significant studies and market potentials. The above mentioned applications, we think of the convenience and cost elements and use the Passive Tag to put into the motor vehicle (example vehicle body, license plate and car glass). These environments will damage and interfere with the radiation of RFID, and cause to influence the range of RFID applications. This research has technical difficulty but has academic values and conform to application of realistic requirement. It’s solutions will enlarge the scope of RFID and spread the RFID applications in daily life. This project will start from the system integrated point of view to utilizing the simulation skill and measurement analysis, at the same time combining with the current RFID technology. Then in order to explore the problems and propose the solutions. It is expected to develop adaptable Tag and RFID technology solutions not only accomplish the identification as the motor vehicles are in motion ( high/medium/low speed) and motionless states, but also enlarge the application scopes of RFID.
