摘　　要：传统的超高频RFID网关无法避免由于多种数据同时在一个网关进程中竞争,将会造成网关的冲突,导致任务失败,从而降低了环境监控信息采集的准确率;为此,设计并实现了基于MC13213的多通道分布式环境监测系统的超高频RFID网关系统;硬件部分详细阐述了基于MC13213的RFID网关设计方法,重点阐述网关终端节点、网关路由节点和网关中心节点的设计方法;软件部分详细阐述了网关进程之间通信机制的设计和网关任务机制数据结构程序设计方法;实验结果表明,利用文章系统能够避免超高频率RFID网关在通信过程中的冲突,提高了环境信息采集的准确率。Traditional UHF RFID gateway is inevitable due to a variety of data in the process of a gateway competition at the same time,the conflict will cause the gateway failed,which reduces the environmental monitoring information acquisition accuracy.To this end,was designed and implemented based on the multi-channel MC13213 distributed environmental monitoring system of UHF RFID gateway system.Hardware part elaborated based on the RFID MC13213 gateway design methods,emphasis on the gateway terminal nodes,gateway routing nodes and gateway nodes at the centre of the design method.Software part in detail in this paper,the design of the communication mechanism between gateways process mechanism and gateway task data structure programming method.The experimental results show that the system presented in this paper can avoid the ultra high frequency RFID gateway in the conflict in the process of communication,improve the accuracy of environmental information collection
