针对供应链环境下现有的EPCGlobal网络存在的问题和信息服务的需求,提出一种基于云计算的射频识别技术(RFID)信息服务架构。该架构将企业的本地RFID应用与供应链公共信息服务解耦,利用基于隐马尔可夫模型的信息分布机制将RFID信息发布到云中,构建起统一的RFID信息服务云平台,为供应链环境下RFID应用提供近实时、序列级的信息服务。将该架构与EPCGlobal网络相比较论证了其优越性。
Given the problems of existing EPCGlobal network and the demand of information service under supply chain environment,this paper provided an innovative architecture for RFID information service based on cloud computing.This architecture decoupled the local enterprise RFID application from public information service,built a unified cloud-based RFID information service platform with using an information distribution mechanism based on hidden markov model(HMM) to mirror RFID information,finally implemented near real-time,serial-level RFID information service.Finally,compared the architecture with the EPCGlobal network and proved its superiority.
