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.
