2、QiangBaoCollegeofCommunicationEngineeringNanjingInstituteofTechnologyJune201073摘要射頻識(shí)別技術(shù)(RFID,即RadioFrequencyIdentification)是從八十年代起走向成熟的一項(xiàng)自動(dòng)識(shí)別技術(shù)。由于大規(guī)模集成電路技術(shù)的成熟,射頻識(shí)別系統(tǒng)的體積大大縮小,因而才進(jìn)入實(shí)用化的階段。它利用射頻方式進(jìn)行非接觸雙向通信,以達(dá)到識(shí)別目的并交換數(shù)據(jù)。它和同期或早期的接觸式識(shí)別技術(shù)不同、RFID系統(tǒng)的射頻卡和讀寫(xiě)器之間不用接觸就可完成識(shí)別。因此它可在更廣泛
3、的場(chǎng)合中應(yīng)用。它可以在產(chǎn)品證件防偽、防盜及科學(xué)化自動(dòng)化管理方面得到應(yīng)用。本文主要介紹了一種基于EM4095的射頻識(shí)別系統(tǒng)的設(shè)計(jì)和實(shí)現(xiàn),該系統(tǒng)可以對(duì)電子標(biāo)簽卡進(jìn)行檢測(cè)、識(shí)別并作相應(yīng)的處理,如顯示卡內(nèi)信息以及判斷此卡的權(quán)限等。系統(tǒng)的控制以單片機(jī)為核心,這里簡(jiǎn)略的介紹了它的一些特點(diǎn)和開(kāi)發(fā)環(huán)境的使用。另外,著重介紹了該系統(tǒng)的功能、結(jié)構(gòu)和各個(gè)模塊的具體設(shè)計(jì)。通過(guò)對(duì)系統(tǒng)軟硬件及功能的測(cè)試,對(duì)測(cè)試中遇到的問(wèn)題進(jìn)行了解決。文章最后對(duì)該系統(tǒng)的應(yīng)用與設(shè)計(jì)做了一個(gè)總結(jié),并對(duì)該系統(tǒng)今后的發(fā)展與研究做了一個(gè)展望。關(guān)鍵詞:?jiǎn)纹瑱C(jī);EM4095;讀卡器;電子標(biāo)
