The Design And The Development Of A Long-Distance RFID System For Distribution Centers

Long-distance RFID systems can identify large objects dynamically. The author designs and develops a long-distance RFID system based on Wireless Net Nodes. This system together with the data management system designed by the author performs the functions of the goods' tracing and the management of distribution information.Firstly, the author analyzes the component architecture, basic theory, data communication, identification algorithm and some key techniques of the RFID system. Through learning CC1010 CMOS chip, the author designs NetReader notes and NetTag notes based on CC1010 CMOS chip functioning as the Reader and the Tag of the long-distance RFID system. Then the author designs the data communication and identification algorithm according to the requirement of the long-distance RFID system, and programs the NetReader notes and the NetTag note to realize the long-distance RFID functions. Finally, the author develops data management software to realize the functions of the goods' tracing and the management of distribution information.The system can perform 1K bytes reading & writing, possesses over five-meter identification distance, has non-conflict mechanism and can support many cards' operation simultaneously. The RFID system designed by the author has met the long-distance RFID requirement of distribution center. Cooperating with the data management system designed by the author, the system can trace distributed goods. It can improve the management level of the distribution centers, and has some study and application values.
