基于有色网的RFID复杂事件检测模型的研究与分析

摘要

Because of the characteristics of RFID data and shortcomings of current several complex event detection models, by expanding Petri nets, this paper proposed a RFID event detection network EDN.It gave the event operator a description of formal and graphical, established complex event expressions hierarchy model, analyzed the conflict algorithm in the event expression and event recycling mechanism.Experimental results demonstrate the correctness and validity of the model.%针对RFID数据的特性以及目前几种复杂事件检测模型的不足,在原有基于Petri网模型的基础上,通过扩展和改进,提出了一种基于有色网的RFID事件检测网EDN,对事件操作符进行了形式化和图形化的描述,建立了复杂事件表达式的层次结构模型;并分析了复杂事件表达式中的冲突算法,给出了RFID事件的资源回收机制,提高了RFID事件的处理能力.通过实验证明了该模型的正确性和有效性.
