图书馆智能管理系统设计

本文详细阐明基于RFID技术设计数字化图书馆智能管理系统的工作原理及其整体结构,并从硬件构成和软件实现两个方面介绍了系统的设计思路;整个系统主要由一台PC机、管理员的读卡器模块、进馆处读卡器模块和出馆处读卡器模块,以及相应的外围控制电路组成.为防止由于标签的数据包在读卡器的接收机中互相碰撞而不能准确读出,系统采用动态ALOHA法,实现对所有标签的读取并进行相应的处理;多个读卡器和PC机联机通信方式采用多串口扩展的组网方式.

Design of Intelligent Management System of Digital Library Based on RFID

This article introduces a design method of intelligent management system of digital library based on RFID.After illustrating the working principle of the system and its whole structure,the designing method is explained from hardware and software design.The whole system consists of a PC,three Reader modules(the guard's room,the entrance,and the exit) and other peripheral circuits.The system uses dynamic ALOHA anti-collision algorithm to read all the tags and make relevant processing in order to avoid reliably the incorrect identification due to the collision of multi-tags'.It also discusses and analyzes communication-network mode between multi-Readers and PC.
