【摘要】：在當(dāng)今管理、物流、交通等領(lǐng)域,物聯(lián)網(wǎng)技術(shù)已得到廣泛利用,其廣大的應(yīng)用前景使其得到迅猛的發(fā)展,射頻識(shí)別技術(shù)(RFID)長(zhǎng)久以來被各國(guó)視為物聯(lián)網(wǎng)技術(shù)發(fā)展的關(guān)鍵。讀寫器作為RFID系統(tǒng)應(yīng)用的重要環(huán)節(jié),直接決定了RFID技術(shù)發(fā)展和推廣,研制一款高性能RFID讀寫器具有重要的科研意義。本文針對(duì)目前國(guó)內(nèi)RFID讀寫器在倉(cāng)儲(chǔ)管理、物流方面的功能單一,性價(jià)比低的應(yīng)用問題,介紹了一款支持多頻段RFID功能的讀寫器的軟件設(shè)計(jì)與實(shí)現(xiàn)。使得該讀寫器同時(shí)具備超高頻ISO 18000-6B/6C協(xié)議,以及微波頻段2.45GHz的GB/T28925協(xié)議的功能。其中,超高頻段的RFID模塊功能滿足了對(duì)大量帶有超高頻的無源標(biāo)簽的物品設(shè)備盤點(diǎn),歸納;微波頻段的RFID模塊功能滿足帶有一定距離的2.45GHz有源標(biāo)簽的盤點(diǎn),同時(shí)在軟件上采用合理的算法,設(shè)計(jì)了兩種模塊在讀寫器中獨(dú)立工作,面對(duì)不同的應(yīng)用場(chǎng)合,采用同一讀寫器,選擇合適頻段的RFID模塊工作,大大減少了人力成本,提高了讀寫器使用效率,具有非常廣闊的應(yīng)用前景。本文首先介紹了RFID技術(shù)及其應(yīng)用發(fā)展情況,通過實(shí)際功能需求分析,介紹了多頻段RFID讀寫器使用A20作為處理器,Android作為操作系統(tǒng)的整體架構(gòu),再依次介紹了硬件架構(gòu)以及方案,根據(jù)多頻段RFID讀寫器軟件方案,并根據(jù)Android系統(tǒng)的軟件架構(gòu)特性提出了所運(yùn)用的軟件編程知識(shí),隨后,根據(jù)兩種頻段的RFID讀寫核心模塊的軟件協(xié)議需求,按照讀寫核心模塊的驅(qū)動(dòng)程序以及中間控制程序、Android應(yīng)用程序以及PC端上位機(jī)程序設(shè)計(jì)的順序,完成和實(shí)現(xiàn)了整個(gè)軟件設(shè)計(jì)。通過最后的軟件測(cè)試結(jié)果總結(jié)設(shè)計(jì)不足之處并提出未來工作的展望。
[Abstract]:Nowadays, Internet of things technology has been widely used in the fields of management, logistics, transportation and so on. Radio Frequency Identification (RFID) has long been regarded as the key to the development of Internet of things technology in many countries. As an important part of the application of RFID system, the reader directly determines the development and popularization of RFID technology. It is of great significance to develop a high-performance RFID reader. This paper aims at the application of RFID reader in warehouse management, logistics and low cost performance. This paper introduces the software design and implementation of a reader that supports multi-band RFID function. The reader has the functions of UHF ISO 18000-6B/6C protocol and microwave band 2.45GHz GB/T28925 protocol. The RFID module function of the UHF band can satisfy the inventory of a large number of items with UHF passive label, and the RFID module function of the microwave frequency band can satisfy the inventory of the active 2.45GHz tag with a certain distance. At the same time, two modules are designed to work independently in the reader by using reasonable algorithm in the software. In the face of different applications, the same reader is used to select the appropriate frequency band RFID module to work, which greatly reduces the labor cost. It improves the efficiency of the reader and has a very broad application prospect. Firstly, this paper introduces the RFID technology and its application development, and analyzes the actual functional requirements. This paper introduces the whole architecture of multiband RFID reader using A20 as processor and RFID as operating system, and then introduces the hardware architecture and scheme in turn, according to the software scheme of multiband RFID reader, According to the software architecture characteristic of Android system, the software programming knowledge is put forward, and then, according to the software protocol requirement of two kinds of RFID read and write core module, According to the driver of the read and write core module, the intermediate control program and the Android application program and PC PC program design order, The software design is completed and realized. The shortcomings of the design are summarized through the final software test results and the prospect of future work is put forward.
