【摘要】：隨著超高頻射頻識(shí)別技術(shù)的不斷發(fā)展,其在防偽、醫(yī)療、倉(cāng)儲(chǔ)、物流、交通等各個(gè)領(lǐng)域都具有非常廣泛的應(yīng)用。在超高頻頻段,目前國(guó)內(nèi)外采用最為廣泛的協(xié)議標(biāo)準(zhǔn)為ISO/IEC18000-6B和6C,為適應(yīng)中國(guó)RFID技術(shù)的戰(zhàn)略發(fā)展,我國(guó)在2011年和2014年開(kāi)始實(shí)施GB/T29768-2013和GJB7377.1-2011兩種超高頻協(xié)議標(biāo)準(zhǔn)。但標(biāo)準(zhǔn)公布之后,目前符合這三種標(biāo)準(zhǔn)協(xié)議的讀寫(xiě)器還很少,因此,設(shè)計(jì)與實(shí)現(xiàn)同時(shí)兼容以上三種協(xié)議標(biāo)準(zhǔn)的多協(xié)議讀寫(xiě)器具有重要意義。本課題的研究正是在上述背景下提出的。本課題通過(guò)對(duì)GB/T29768-2013、GJB7377.1-2011和ISO/IEC18000-6C三個(gè)協(xié)議標(biāo)準(zhǔn)的物理層及協(xié)議工作方式的對(duì)比分析,采用對(duì)整個(gè)軟件系統(tǒng)模塊劃分的軟件設(shè)計(jì)方案,將讀寫(xiě)器軟件系統(tǒng)分為應(yīng)用接口模塊、參數(shù)配置模塊、射頻控制模塊以及協(xié)議處理模塊。文中對(duì)應(yīng)用接口模塊的三個(gè)子模塊:核心狀態(tài)機(jī)、串口通信模塊和命令解析模塊均給出了分析與實(shí)現(xiàn)。在協(xié)議處理模塊中,對(duì)三種協(xié)議下的強(qiáng)制性命令均給出了詳細(xì)的分析設(shè)計(jì)與實(shí)現(xiàn)流程,并且對(duì)三種協(xié)議的防碰撞算法:時(shí)隙化的隨機(jī)防碰撞算法以及動(dòng)態(tài)分散收縮二叉樹(shù)算法做了分析與實(shí)現(xiàn)。通過(guò)上述努力,研究和實(shí)現(xiàn)了基于ZYNQ-7000系統(tǒng)平臺(tái)的多協(xié)議UHF RFID讀寫(xiě)器軟件設(shè)計(jì)。該軟件實(shí)現(xiàn)同時(shí)滿足GB/T29768-2013、GJB7377.1-2011和ISO/IEC18000-6C三種協(xié)議標(biāo)準(zhǔn),具備三種協(xié)議下的單標(biāo)簽與多標(biāo)簽的盤(pán)存、單標(biāo)簽讀寫(xiě)、鎖定和殺死標(biāo)簽等功能,測(cè)試表明基于ZYNQ-7000平臺(tái)的多協(xié)議UHF RFID的讀寫(xiě)器軟件設(shè)計(jì)滿足設(shè)計(jì)指標(biāo)要求。隨著我國(guó)超高頻RFID的逐漸發(fā)展,可以預(yù)見(jiàn),同時(shí)符合GB/T29768-2013、GJB7377.1-2011和ISO/IEC18000-6C三種協(xié)議的UHF RFID讀寫(xiě)器將成為發(fā)展趨勢(shì),該多標(biāo)準(zhǔn)讀寫(xiě)器將在防偽、醫(yī)療、倉(cāng)儲(chǔ)、物流、交通等方面獲得廣泛應(yīng)用。
[Abstract]:With the development of UHF RFID technology, it has been widely used in many fields, such as anti-counterfeiting, medical treatment, storage, logistics, transportation and so on. At present, ISO / IEC18000-6B and 6Care the most widely used protocol standards at home and abroad in UHF frequency band. In order to adapt to the strategic development of RFID technology in China, two UHF protocol standards GB / T29768-2013 and GJB7377.1-2011 were implemented in 2011 and 2014. However, after the publication of the standards, there are few readers who conform to these three standard protocols, so it is of great significance to design and implement a multi-protocol reader compatible with the above three protocol standards at the same time. The research of this subject is put forward under the above background. Through the comparative analysis of the physical layer and the working mode of the three protocol standards of GB / T29768-2013GJB7377.1-2011 and ISO / IEC18000-6C, the software design scheme of dividing the whole software system module is adopted, and the reader software system is divided into application interface module and parameter configuration module. Radio frequency control module and protocol processing module. In this paper, three sub-modules of the application interface module, namely, the core state machine, the serial communication module and the command analysis module, are analyzed and implemented. In the protocol processing module, the detailed analysis, design and implementation flow of the mandatory commands under the three protocols are given. The anti-collision algorithms of three kinds of protocols are analyzed and implemented: the stochastic anti-collision algorithm based on time slot and the binary tree algorithm of dynamic dispersion shrinkage. Through the above efforts, the software design of multi-protocol UHF RFID reader based on ZYNQ-7000 system platform is studied and implemented. The software meets the standards of GB / T29768-2013GJB7377.1-2011 and ISO / IEC18000-6C at the same time, and has the functions of inventory of single label and multi-label, single-label reading and writing, locking and killing tag, etc. The test results show that the reader software design of multi-protocol UHF RFID based on ZYNQ-7000 platform meets the design requirements. With the development of UHF RFID in China, it can be predicted that the UHF RFID reader, which accords with the three protocols of GB / T29768-2013, GJB7377.1-2011 and ISO / IEC18000-6C, will become a developing trend. The multi-standard reader will be widely used in the fields of anti-counterfeiting, medical treatment, warehousing, logistics, transportation and so on.
