基于SOA的RFID复杂事件处理的中间件模型的研究

Research of RFID Middleware Model with CEP Based on SOA

RFID中间件被认为是RFID系统的神经.首先分析和讨论了一些相对成熟的RFID中间件,提出了一种基于SOA的RFID中间件.其次介绍了复杂事件处理(CEP),它是一种新的事件和数据处理的技术.随着RFID技术的广泛使用,复杂事件处理在RFID应用中显得越来越重要.基于RFID中间件引入CEP的基本原理,提出了一种基于CEP的数据处理模型,介绍了缓存器,事件过滤器以及复杂事件构造器的关键技术.另外,我们也介绍了一种检测RFID复杂事件的查询语言.

RFID middleware is regarded as the nerve of RFID systems.Firstly this paper analysis and discuss relatively mature RFID middleware,and propose a RFID middleware which based on serviceoriented architecture.Then the CEP（complex event processing）was introduced,and it is a new technology for event and data processing.With the widespread usage of RFID technology,complex event processing becomes a very important part in RFID application.Based on introducing CEP to RFID middleware,a CEP data processing model was proposed,and cache,Event Filter and Complex Event Builder key technologies was studied.Moreover,aquery language for detecting RFID complex events is also introduced.
