超高频RFID标签可重用仓储管理系统的设计

Design on Warehouse Management System Based on Reusable UHF RFID Tags

超高频RFID标签感应距离远、读取速度快和抗干扰能力强,应用于仓储管理系统可以提高其管理效率。针对中小型仓储应用提出物品入库关联RFID标签,出库解除关联,RFID标签可重复使用。采用静态字典编码和时间压缩算法对单一仓储物品信息压缩编码至128比特,通过对RFID标签顺序增计数编号,二维表被简化为线性表并存储在RFID阅读器中,RFID阅读器将仓储数据同步更新管理数据库。讨论了仓储管理系统RFID阅读器的硬件及软件设计架构。仓储物品信息压缩编码和数据顺序存储降低了系统对RFID阅读器硬件和存储资源的需求。

Ultra-high frequency RFID tags with such features as long response distance,fast read speed and high anti-interference can improve warehouse management system efficiency.A novel warehouse management method is proposed,in which RFID tag is reused by linking and unlinking with cargo.Through static dictionary coding and time compressing,the information of a cargo is coded into 128 bits data.A linear table is stored into RFID reader through increasing the RFID tag＇s ID.RFID reader synchronizes warehouse data to management database.Finally,the structure of hardware and software about RFID reader is discussed.The information compressing and data sequential storage in warehouse management system reduces the requirements for RFID reader on hardware and storage resources.
