基于嵌入式Linux物流RFID读写器的设计与实现

Design of Logistic RFID Reader Based on Embedded Linux

旨在设计一款基于嵌入式Linux的物流RFID标签读写器,具有多种接入网络的方式的通信接口,以适应在大规模分布式物流供应链环境下应用。其特点是嵌入式操作系统,有独立的嵌入数据库。由于有了数据库的支持,在网络拥塞或中断时,读写器也可以继续工作,把读到的标签数据先存放到本地数据库,网络恢复正常,再把本地数据库中的数据上传到主服务器。本读写器采用模块化的设计思想,拥有可定制,可升级,可更新高级特性。

This paper is mainly focus on the design of a new kind of logistics RFID label reader in the embedded Linux system. The reader has several kinds of communicate interfaces and they are used to adapt the environment of large scale distribute logistics supply chains.The characteristic of the reader is embedded operating system and the independent embedded database.Thanks to the support of database,the reader will go on working if the congestion or suddenly break in the network.The label data read by the reader are firstly preserved in the native database,if the network returns to normal,then the data will be transported to the main server.This reader adopts the modularized design idea,with the characteristics of customizable,upgradable,renewable.
