Design of Intelligent Book Ranging System Based on RFID Technology and FPGA Main Control Module
In order to improve the efficency of users searching and obtain tagget books on bookshelves,an intelligent book ran-ging system is designed based on RFID technology and FPGA main control module.The overall architecture of the intelligent book ranging system is designed,which is composed of RFID system,FPGA main control module and display module.The composition of RFID system is analyzed in detail,the communication framework of intelligent book ranging system is designed,and the principle flow of book phase difference ranging,least square fitting algorithm and system ranging method are described.The instruction flow of the intelligent book ranging system is designed,and the Simulink of MATLAB is used for height fitting and visual simulation test.The test shows that the system runs smoothly and the error range of electronic tag ranging is small(0.1-5.0 cm),which can meet the system design requirements of accurate ranging in bookshelves,rapid discovery and acquisi-tion of designated books.
