摘　　要：为了使RFID中间件能够分布式部署,并满足以太网与ZigBee无线网络共存的需求,分析了业界主流RFID中间件的设计技术,并设计了基于ZigBee的分布式中间件[1]解决方案。将中间件划分为数据采集边缘服务器和数据采集中心服务器两部分,通过数据采集中心服务器远程管理边缘服务器的方式,有效解决了分布式部署问题。设计了多网络协议模块,该模块可以自适应地选择不同网络协议的接口,从而实现多网络共存。在实现过程中,针对应用层事件协议(ALE)、数据过滤器等关键技术,给出了应用层事件核心模块和过滤器模块的解决方案。In order to support distributed deployment and coexistence of Ethemet and ZigBee, the technology of mainstream RFID middleware is studied and a distributed middleware based on mixed network is designed. Firstly, the middleware is divided into data acquisition which is also called edge server and data collection parts which can manage and control the former one. Secondly, to support the coexistence of Ethemet and ZigBee, a multi-protocol module which supports both Ethernet and ZigBee is used. The module has the feature of switching between Ethemet and ZigBee, and it is designed to support more other network protocol. Finally, solutions for the application level events （ALE） protocol, data filters and other technologies are presented in the implementation part.
