普适的RFID网络模型研究

为了适应物联网不同应用间的异构性，设计了一种普适的RFID网络模型，介绍了模型中的层次结构并着重研究了RFID网络中的事件处理层和信息服务层。在事件处理层上使用EPCglobal颁布的应用级别事件AI正（Application Level Event）规范，规范定义了RFID事件过滤和采集接口，使得从标签读取到应用接收过程中保持数据处理、接收的一致性；在信息服务层采用发布／订阅机制，设计不同的发布／订阅方法，使在企业应用和RFID网络间数据实现灵活交互，基本满足了企业应用的各种需求。

Research for Universal RFID Network Model

In order to adapt to different application of the heterogeneous internet of things, design a kind of a universal RFID network model, introduce the hierarchical structure of the model and focus the study on event handling layer and information service layer. In the event handling layer use ALE（ Application Level Event） standard which is issued by EPC global ,this standard defines RFID events filtering and collecting interfaces, it can keep consistency from the process of reading labels to receiving data. In the information service layer use publish/subscribe mechanism, through different publish/subscribe methods, data between enterprise application and RF1D network re- atizes flexible interaction, this can meet different needs of enterprise application.
