Research And Design Of Intelligent Bookshelf Management System Based On UHF RFID Technology

The library is an important place for the dissemination of human knowledge and the centralized circulation of information resources.The rapid development of Internet technology and the widespread application of the intelligent Internet of Things have made the technical support and operation of the library continue to innovate.In the face of a large number of book resources and a huge readership,the management model and service methods of the library are facing many challenges.Since 2006,more and more domestic libraries have begun to introduce radio frequency identification technology.The rapid development of this technology has gradually replaced the traditional bar code technology,changed the management and operation mode of the library,and realized intelligent book sorting and self-service borrowing and returning.,Security access control,automated inventory and other comprehensive intelligent management systems,the mature application of RFID technology has become an important symbol of the library's realization of intelligent management.This paper studies the development status of RFID technology in libraries at home and abroad in detail,summarizes the currently widely used book inventory methods,and addresses the problems of serious book mis-shelf,difficulty in finding books,and low inventory efficiency under the development trend of library open-shelf lending.An intelligent bookshelf management system based on the existing bookshelves in the library is proposed,which is based on hardware improvement and technical optimization.The feasibility analysis is carried out from different angles.In this paper,the RFID indoor positioning algorithm is applied to book positioning,and the LANDMARC positioning system model is built in MATLAB.The positioning accuracy and algorithm stability are evaluated from four aspects: the number of nearest neighbor reference tags,the weight definition method,the reference tag density,and environmental factors.Through simulation analysis,the optimal parameters of the algorithm are determined,and the original algorithm is improved.The positioning accuracy of the improved algorithm has been significantly improved.The intelligent bookshelf system researched and designed in this paper is based on UHF RFID technology that conforms to the ISO 18000-6C protocol,and is composed of a reader,an antenna,an electronic tag,and a function-rich host computer platform.The article analyzes and researches the intelligent bookshelf system in detail from two aspects of hardware structure and software design.The system divides the existing bookshelf into several small units on the hardware structure,and adds a reference label containing the shelf information of the bookshelf in each unit to assist book positioning.According to the research of indoor positioning algorithm,the distribution and quantity of reference labels are made.Detailed introduction.The reference tag,the book tag,and the reader antenna constitute a positioning system,which locates the book tag according to the indoor positioning algorithm,matches the specific location information with the book tag,and uses more intuitive book location information to find the book when searching for the book.The realization of book positioning not only makes it convenient for users to quickly find a large number of books,but also provides great convenience for the business processes of book inventory,put-away,and wrong-shelf sorting.It greatly improves the efficiency of book management and provides solutions for current library problems.A good solution.
