【摘要】 由于存在漏读、交叉读以及语义简单的原子事件,RFID系统产生的海量原始数据无法直接融合到企业现有的管理系统中.RFID中间件作为原始数据和上层应用之间的桥梁,有着非常重要的作用.开发了一种RFID数据管理中间件原型系统RFeel.该中间件可以屏蔽异构读写器平台差异、以统一数据格式向上层提供通用接口,包含了交叉读数据仲裁、不确定性数据推导、分布式复杂事件的检测、复杂事件处理优化和聚集查询等核心技术.最后通过一个典型的零售场景演示了RFeel的工作过程.更多还原

【Abstract】 Missing or crossing readings are common for raw RFID data caused by the signal interference and environment noises.The raw data readings are primitive RFID events containing little semantics.Because of the raw RFID data reading problems,they cannot be directly integrated into existing information management systems.Before raw RFID data can be used with high-level applications,an RFID middleware can play a critical role to clean and correct the data.A middleware nameed RFeel was designed and developed in this paper.RFeel supported heterogeneous RFID readers and provided common interfaces for high-level applications.The core technologies employed in RFeel include arbitration of crossing RFID readings,inference over uncertain RFID data,optimizing techniques for complex event processing,aggregate queries over complex events,and complex event processing in a distributed environment.Finally an initial prototype of RFeel was demonstrated through a real-world retail management scenario.更多还原
