| RFID(Radio Frequency Identification)is a key technology in the field of IoT(Internet of Things).It has been widely applied in many areas,such as vehicle traffic,shipping,express delivery,freight transportation,object tracking and so on.And because of the UHF RFID having many advantages,such as fast transmission speed,high accuracy about data reading and writing,it is a developing trend in the future.It has been focused on library management field,and has been applied to practice.This paper introduces the system composition,working principle,classification,communication security protocol and other basic theoretical knowledge of RFID.This paper deeply researches and analyzes the most critical technology of RFID radio frequency technology,conflict prevention technology,which includes researching and analyzing the basic principles of collision and anti-collision algorithms.This paper studies the improvement of RFID's guard against theft,and expounds the following four aspects: the selection of RFID working frequency,the assembling and commissioning of the anti-theft detection,the performance of reader,the detection and protection of electronic label.Through comparing the advantages and disadvantages of three modes: magnetic stripe theft prevention,RFID anti-theft and RFID+ magnetic stripe anti-theft,this paper puts forward anti-theft solution of library data based on RFID+ recharging and degaussing strip,and also carries out necessary verification about its correctness and validity.This paper studies common encryption algorithms and their advantages and disadvantages.Combined with the actual needs of Library RFID system application,ECC security encryption algorithm is selected to meet the library's application requirements for RFID,and an anti-theft method suitable for Intelligent Library RFID system application is designed.This paper studies the improvement of RFID's anti-theft effect,and expounds the possibility of improving the anti-theft effect of RFID from four aspects,such as RFID tag frequency,debugging of RFID anti-theft detector,performance of reader and detection of RFID label.This paper puts forward a solution about library burglar detection instrument based on RFID+ recharge degaussing strip.Through comparative analysis,it is concluded that the charging and degaussing bar anti-theft detector based on RFID+ can not only give full play to the advantages of RFID in library intelligent management,but also give full play to the reliability and economic efficiency of magnetic stripe theft prevention,which is a feasible scheme at the present stage.This paper verifies the scheme of the anti-theft detection.Through the optimization of the typical self-help loan book process,making the work of magnetic strips to be solidified on the self-help loan return terminal to improve the user experience. |
