Arm Processor-based Rfid Reader Developed

With the fast development of modern information technology, the processing of RFID information needs to be increased fastly, so it is important to design a new RFID reader for automatic recieving and managing the data from the vincinity or the distant cards. In recent years, the development of RFID technology has put the achievement of RFID processing in theory into new practical application systems and then new theory and application have been made great progress.Firstly, not only the important of the dissertation but also the application and the developement of the RFID reader are presented, then we describe the frame and the principle of the RFID systems and breifly give related communication protocol of the RFID. RI-I02-112B label structure are given as an example in the same time. Secondly we breifly introduce the ARM processor and describe how to select the chip based on ARM in practice. in detail The dissertation emphasis the embedded system structure of the hardware and the software based on S3C44b0X processor. We used the C lauguage and assemble lauguage combination program to realize the BOOTLOADER. Then transplant the UCLINUX into the system.At the last chapter, we discribe the research of the RFID reader system based on S3C44B0X processor in detail, including the design of the hardware such as the antenna part, reader part and MCU part, the design of software about the ISO15693 communication protocol. And the main program of the reader are presented at the same time .The system is different from the other common RFID reader system which based on C51 series microprossor in a moveable and portable system. The system uses S3C44BOX processor which is suitable in low cost and dissppation and main clock can reach 130MIPS, so the system can increase the data processing greatly, matching the data transport demanded from the RFID label to the RFID reader. The reader not only can recieve the data from the RFID label but also can deal with the data which have been received. Meanwhile the system have the good communication function that makes us realize the auto identified and remoted controlled from the extend module. In...
