【摘要】：作為一種快速、實時收集和處理信息的高新技術,射頻識別(Radio Frequency Identification,RFID)被公認為21世紀十大關鍵技術之一。RFID應用系統(tǒng)一般由標簽、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中間件在實現(xiàn)硬件設備與企業(yè)應用對接的基礎上,必須為企業(yè)提供有效的業(yè)務信息。為使中間件能夠?qū)崟r、有效地將原始數(shù)據(jù)轉(zhuǎn)化為業(yè)務信息,本文將復雜事件處理技術應用到RFID中間件中,設計并實現(xiàn)了基于復雜事件處理的RFID中間件。首先,結合國內(nèi)外研究現(xiàn)狀以及對RFID中間件的功能需求分析,設計了RFID中間件四層架構,分為邊緣服務層、數(shù)據(jù)過濾層、事件處理層和事件發(fā)布層,并對各層功能模塊進行了概述。其次,對RFID中間件各層進行了詳細設計與實現(xiàn)。邊緣服務層主要實現(xiàn)對RFID閱讀器的統(tǒng)一管理和標簽數(shù)據(jù)格式的統(tǒng)一;數(shù)據(jù)過濾層通過去重過濾器、平滑過濾器和屬性過濾器得到滿足用戶需求且可靠、有效的數(shù)據(jù);事件處理層通過復雜事件處理技術,利用復雜事件處理引擎Esper實時地將有效數(shù)據(jù)轉(zhuǎn)化為業(yè)務事件;事件發(fā)布層利用Active MQ消息中間件,將業(yè)務事件發(fā)送到對應主題訂閱的企業(yè)應用,同時將業(yè)務事件持久化到My SQL數(shù)據(jù)庫。最后,利用中間件對港口物流配送的業(yè)務事件進行了模擬仿真,同時對中間件事件檢測效果和時延性能進行了測試。實驗結果表明,本文設計的RFID中間件基本能夠滿足對海量數(shù)據(jù)的實時事件處理功能,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.
