Research On Anti-collision Algorithm For Book Labels In Library Intelligent Borrowing And Returning Books System

With the rapid development of RFID technology,the application of RFID technology in libraries has become an inevitable trend of intelligent and information development of libraries.At present,the management method of libraries has been difficult to meet the growing needs of readers.How to make better use of RFID technology to improve the quality of library management and service has become a new challenge.This thesis studies the application of RFID library intelligent borrowing and returning system and anti-collision algorithm of book tags.This paper first introduces the development status of libraries using RFID technology at home and abroad,and then introduces RFID technology and hardware components.In this paper,the use of UHF tags is smaller,easy to hide in the back of the book and not found by readers,faster reading and writing,shorter response time for self-service borrowing and returning books,cheaper prices,and can effectively reduce RFID books.The cost of library construction and other characteristics,choose to use ultra-high frequency(UHF)tags.In order to better coordinate the communication between the reader and the tag,the random ALOHA anti-collision algorithm and the deterministic binary tree anti-collision algorithm are introduced.The standards given in China's air interface protocol for UHF tags are also studied.The anti-collision algorithm has been improved.Through comparative experiments,the experimental results show that the improved algorithm can effectively improve the query efficiency.In the subsequent chapters of the paper on the design and implementation of the library intelligent borrowing and returning system,the improved binary tree anti-collision algorithm is used to effectively prevent the conflict of tags.In this thesis,the RFID smart book borrowing and returning system is also designed,showing the overall design architecture of the system,and the design and implementation of each sub-module in the system are completed.Its main functions include the self-service borrowing and returning function of RFID library books.,Book borrowing and query function,and gives the process of system programming implementation.This system can effectively improve the managementefficiency of the librarians,reduce the library's cost investment in book management,effectively shorten the waiting time for borrowing by the majority of readers,and has good practical application value.
