【摘要】：作为一种快速、实时收集和处理信息的高新技术,射频识别(Radio Frequency Identification,RFID)被公认为21世纪十大关键技术之一。RFID应用系统一般由标签、阅读器、RFID中间件和企业管理系统四部分组成。作为系统核心环节的RFID中间件在实现硬件设备与企业应用对接的基础上,必须为企业提供有效的业务信息。为使中间件能够实时、有效地将原始数据转化为业务信息,本文将复杂事件处理技术应用到RFID中间件中,设计并实现了基于复杂事件处理的RFID中间件。首先,结合国内外研究现状以及对RFID中间件的功能需求分析,设计了RFID中间件四层架构,分为边缘服务层、数据过滤层、事件处理层和事件发布层,并对各层功能模块进行了概述。其次,对RFID中间件各层进行了详细设计与实现。边缘服务层主要实现对RFID阅读器的统一管理和标签数据格式的统一;数据过滤层通过去重过滤器、平滑过滤器和属性过滤器得到满足用户需求且可靠、有效的数据;事件处理层通过复杂事件处理技术,利用复杂事件处理引擎Esper实时地将有效数据转化为业务事件;事件发布层利用Active MQ消息中间件,将业务事件发送到对应主题订阅的企业应用,同时将业务事件持久化到My SQL数据库。最后,利用中间件对港口物流配送的业务事件进行了模拟仿真,同时对中间件事件检测效果和时延性能进行了测试。实验结果表明,本文设计的RFID中间件基本能够满足对海量数据的实时事件处理功能,能够快速、有效地将原始数据转化为企业需求的业务信息。
[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.
