EPCglobal应用层事件引擎设计与实现

射频识别中间件的推出很好地解决了将物理基础架构收集到的信息传递给企业应用程序并且被企业应用程序所使用的技术与成本问题，加速了射频识别技术的推广使用。该文介绍了一个支持EPCglobal应用层事件规范的射频识别中间件引擎，引擎由内核模块、设备管理模块、事件过滤模块和配置模块组成，将应用程序和设备接口分离，过滤和处理读卡器捕获的原始观测值，提供设备管理和查询的应用程序级接口等功能。阐述该服务器的功能结构、设计和实现。

Design and Implementation of EPCglobal Application Level Events Engine

Radio-Frequency Identification(RFID) middleware turns out to be the right solution for exposing and digesting the information collected by physical infrastructure for enterprise applications, which in practice accelerates the widely-using of RFID technology. This paper introduces an RFID middleware, which supports the EPCglobal Application Level Events(ALE) specification. The engine is composed of four modules, which are kernel module, device management module, event filter module, and configuration module. The engine provides features to encapsulate the applications from device interfaces, processes the raw observations captured by the readers and sensors, and provides an application-level interface for managing readers and querying RFID observations. The functional architecture, design and implementation of the engine are discussed.
