【摘要】：傳統(tǒng)的門禁系統(tǒng)采用有線數(shù)據(jù)通信方式,系統(tǒng)部署受到環(huán)境限制較多,其系統(tǒng)功能僅限于對來訪人員身份的識別,無法提供或者融合進(jìn)諸如便捷的戶外數(shù)據(jù)采集,向移動(dòng)設(shè)備端主動(dòng)信息推送等新型移動(dòng)應(yīng)用。射頻身份識別(Radio Frequency IDentification, RFID)是一種非接觸式自動(dòng)識別技術(shù),經(jīng)過不斷發(fā)展和普及,在眾多領(lǐng)域廣泛應(yīng)用。近場耦合通信(Near Field Communication, NFC)技術(shù)作為RFID在移動(dòng)應(yīng)用領(lǐng)域的先進(jìn)解決方案,近年來在移動(dòng)終端設(shè)備一側(cè)迅速普及,如手機(jī)、平電腦、個(gè)人數(shù)字助理等,能提供身份識別、電子支付、信息共享等移動(dòng)應(yīng)用。本文融合當(dāng)前大數(shù)據(jù)背景下數(shù)據(jù)業(yè)務(wù)移動(dòng)推送的需求,設(shè)計(jì)一種將Zigbee傳感網(wǎng)絡(luò)、近場耦合通信以及傳統(tǒng)門禁技術(shù)相結(jié)合的整體解決方案。該身份識別功能系統(tǒng)支持快速無線部署；具有傳統(tǒng)門禁系統(tǒng)不可比擬的無線數(shù)據(jù)傳輸功能;融合近場耦合通信支持移動(dòng)終端設(shè)備等優(yōu)點(diǎn),可廣泛應(yīng)用于戶外場所或其他數(shù)據(jù)推送的場景中。論文主要工作包括：1、研究現(xiàn)有門禁系統(tǒng)應(yīng)用現(xiàn)狀、技術(shù)特點(diǎn)和發(fā)展趨勢。對比分析了數(shù)種常見的短距通信技術(shù),重點(diǎn)研究了Zigbee無線傳感網(wǎng)絡(luò)的技術(shù)方案。在此基礎(chǔ)上,深入研究了NFC通信的實(shí)現(xiàn)原理、過程、數(shù)據(jù)格式等技術(shù)細(xì)節(jié)。重點(diǎn)分析了Zigbee無線傳感網(wǎng)絡(luò)技術(shù)和NFC技術(shù)融合在門禁系統(tǒng)中實(shí)現(xiàn)的可行性和必要性。2、對門禁系統(tǒng)進(jìn)行了系統(tǒng)級規(guī)劃與設(shè)計(jì),并在此基礎(chǔ)上詳細(xì)設(shè)計(jì)了各個(gè)部分的硬件,詳細(xì)討論了系統(tǒng)原理、設(shè)計(jì)細(xì)節(jié)、計(jì)算和結(jié)果。3、基于軟件工程的思想和方法對嵌入式軟件和門禁系統(tǒng)上位機(jī)軟件進(jìn)行需求分析、概要設(shè)計(jì)和詳細(xì)設(shè)計(jì),實(shí)現(xiàn)了Zigbee協(xié)議棧功能的二次開發(fā)、NFC通信軟件、外圍控制器運(yùn)行維護(hù)及上位機(jī)軟件等軟件開發(fā)、測試和調(diào)試。系統(tǒng)整體測試與評估結(jié)果表明,所設(shè)計(jì)的門禁系統(tǒng)達(dá)到預(yù)期設(shè)計(jì)要求,為解決靈活、快速部署以及數(shù)據(jù)推送等移動(dòng)業(yè)務(wù)提供了有效的解決方案。
[Abstract]:The traditional access control system uses wired data communication mode, the system deployment is limited by the environment, its system function is limited to the identification of visitors, it can not provide or merge into such convenient outdoor data collection, New mobile applications such as pushing active information to the end of mobile devices. Radio Frequency Identification (Radio Frequency IDentification, RFID) is a contactless automatic identification technology, which has been widely used in many fields through continuous development and popularization. As an advanced solution of RFID in the field of mobile applications, near field coupled communication (NEM) Field Communication, NFC) technology has been rapidly popularized on the side of mobile terminal devices in recent years, such as mobile phones, flat computers, personal digital assistants, etc., which can provide identification, electronic payment, etc. Information sharing and other mobile applications. This paper combines the requirement of mobile push of data services under the current big data background, and designs a solution that combines Zigbee sensor network, near-field coupling communication and traditional access control technology. The identification function system supports rapid wireless deployment, has the advantages of wireless data transmission functions that are incomparable to traditional access control systems, and integrates near-field coupled communications to support mobile terminal devices, and so on. Can be widely used in outdoor places or other data push scenes. The main work of this paper is to study the application status, technical characteristics and development trend of the existing access control system. Several common short-distance communication technologies are compared and analyzed, and the technical scheme of Zigbee wireless sensor network is studied emphatically. On this basis, the realization principle, process, data format and other technical details of NFC communication are studied in depth. The feasibility and necessity of the integration of Zigbee wireless sensor network technology and NFC technology in the access control system are analyzed, and the system level planning and design of the access control system are carried out. On this basis, the hardware of each part is designed in detail. The principle, design details, calculation and result of the system are discussed in detail. Based on the idea and method of software engineering, the requirement analysis, outline design and detailed design of embedded software and upper computer software of access control system are carried out. The secondary development of Zigbee stack function is realized, including the software development, testing and debugging of peripheral controller operation and maintenance, and host computer software. The overall test and evaluation results show that the designed access control system meets the expected design requirements, and provides an effective solution for mobile services such as flexibility, rapid deployment and data push.
