Research On Portable RFID System Based On Embedded System

With the development of automation identification,more and more attention has been paid to RFID(Radio Frequency Identification)technology at automation identification and data acquisition domain.The work efficiency of the management department of government and the security of the vehicle datum will be improved effectively if the RFID technology is applied in the vehicle management system.But at present most of the RFID system is immobile.Therefore it is important and significant for us to study RFID system based on embedded system.This system can be used in the management system of cars and so on.Firstly,based on a lot of literature an overview of RFID technology is presented including the principle,classification and the development of RFID technology.Secondly,the basic conceptions of embedded system are presented.Finally,A RFID reader based on embedded system is designed on the basis of analysis of the theories and application of the embedded system.In order to realize the project,the RFID reader system is designed,in which LPC2210 and ZLG500 middle range reader module as the main device,including Nor Flash,Nand Flash,PSRAM,serial communication are used.At the same time,the multiple tasks software system on the basis of the embedded real-time operation systemμC/OS-Ⅱ,including replantingμC/OS-Ⅱto LPC2210,and the software of other modules are designed.After being tested and optimized,a qualified RFID system has been completed,which is then implemented in the project.In conclusion,the design is of great expansibility and flexibility, and attains some useful results which will contribute to further research of RFID system.
