【摘要】：作為一種快速、實(shí)時(shí)收集和處理信息的高新技術(shù),射頻識(shí)別(Radio Frequency Identification,RFID)被公認(rèn)為21世紀(jì)十大關(guān)鍵技術(shù)之一。RFID應(yīng)用系統(tǒng)一般由標(biāo)簽、閱讀器、RFID中間件和企業(yè)管理系統(tǒng)四部分組成。作為系統(tǒng)核心環(huán)節(jié)的RFID中間件在實(shí)現(xiàn)硬件設(shè)備與企業(yè)應(yīng)用對(duì)接的基礎(chǔ)上,必須為企業(yè)提供有效的業(yè)務(wù)信息。為使中間件能夠?qū)崟r(shí)、有效地將原始數(shù)據(jù)轉(zhuǎn)化為業(yè)務(wù)信息,本文將復(fù)雜事件處理技術(shù)應(yīng)用到RFID中間件中,設(shè)計(jì)并實(shí)現(xiàn)了基于復(fù)雜事件處理的RFID中間件。首先,結(jié)合國(guó)內(nèi)外研究現(xiàn)狀以及對(duì)RFID中間件的功能需求分析,設(shè)計(jì)了RFID中間件四層架構(gòu),分為邊緣服務(wù)層、數(shù)據(jù)過(guò)濾層、事件處理層和事件發(fā)布層,并對(duì)各層功能模塊進(jìn)行了概述。其次,對(duì)RFID中間件各層進(jìn)行了詳細(xì)設(shè)計(jì)與實(shí)現(xiàn)。邊緣服務(wù)層主要實(shí)現(xiàn)對(duì)RFID閱讀器的統(tǒng)一管理和標(biāo)簽數(shù)據(jù)格式的統(tǒng)一;數(shù)據(jù)過(guò)濾層通過(guò)去重過(guò)濾器、平滑過(guò)濾器和屬性過(guò)濾器得到滿足用戶需求且可靠、有效的數(shù)據(jù);事件處理層通過(guò)復(fù)雜事件處理技術(shù),利用復(fù)雜事件處理引擎Esper實(shí)時(shí)地將有效數(shù)據(jù)轉(zhuǎn)化為業(yè)務(wù)事件;事件發(fā)布層利用Active MQ消息中間件,將業(yè)務(wù)事件發(fā)送到對(duì)應(yīng)主題訂閱的企業(yè)應(yīng)用,同時(shí)將業(yè)務(wù)事件持久化到My SQL數(shù)據(jù)庫(kù)。最后,利用中間件對(duì)港口物流配送的業(yè)務(wù)事件進(jìn)行了模擬仿真,同時(shí)對(duì)中間件事件檢測(cè)效果和時(shí)延性能進(jìn)行了測(cè)試。實(shí)驗(yàn)結(jié)果表明,本文設(shè)計(jì)的RFID中間件基本能夠滿足對(duì)海量數(shù)據(jù)的實(shí)時(shí)事件處理功能,能夠快速、有效地將原始數(shù)據(jù)轉(zhuǎn)化為企業(yè)需求的業(yè)務(wù)信息。
[Abstract]:As a fast, real-time collection and processing of information, RFID Radio Frequency Identification. RFID) is recognized as one of the top ten key technologies in 21th century. RFID applications are generally made up of tags and readers. RFID middleware and enterprise management system are composed of four parts. As the core link of the system, RFID middleware realizes the docking between hardware equipment and enterprise application. It is necessary to provide effective business information for enterprises. In order to enable middleware to transform raw data into business information in real time, this paper applies complex event processing technology to RFID middleware. The RFID middleware based on complex event processing is designed and implemented. Firstly, the four-tier architecture of RFID middleware is designed based on the analysis of domestic and international research status and the functional requirements of RFID middleware. It is divided into edge service layer, data filtering layer, event processing layer and event publishing layer, and the functional modules of each layer are summarized. Secondly. The RFID middleware layer is designed and implemented in detail. The edge service layer mainly realizes the unified management of RFID reader and the unification of tag data format. The data filter layer obtains reliable and effective data to meet the user's needs by removing the heavy filter, smoothing filter and attribute filter. The event processing layer uses the complex event processing engine Esper to transform the effective data into the business event in real time through the complex event processing technology. The event publishing layer makes use of Active MQ messaging middleware to send business events to the corresponding subject subscription enterprise application, and at the same time to persist the business events to my SQL database. Finally. The business events of port logistics distribution are simulated by middleware, and the performance of middleware event detection and delay is tested. The experimental results show that. The RFID middleware designed in this paper can basically satisfy the real-time event processing function of massive data, and can quickly and effectively transform the raw data into business information required by the enterprise.
