Design And Implementation Of Book Location System Based On High Frequency RFID

With the development of modern library,readers are more and more difficult to find books,the workload of librarians and the inaccurate data of book analysis.The most fundamental solution to these problems is to use modern information technology to realize real-time positioning of books.The research and application of book positioning system has theoretical and practical significance in improving the quality of public service,promoting the utilization rate of library collection and improving the level of book management.This paper first analyzes the current library readers find books difficult,management workload and other problems;then compares the characteristics of different technical means and solutions to achieve book positioning at home and abroad,and focuses on the advantages and disadvantages of using RFID inventory car and RFID intelligent bookshelf;Finally,the paper analyzes the development status of book positioning by using intelligent bookshelf scheme from the aspects of technology selection and performance research.On this basis,the design and implementation of book positioning system based on high frequency RFID is proposed.The main contents of this paper are as follows:(1)According to the requirements of the system,the overall scheme of the book positioning system is put forward.The main objectives of the system include improving the efficiency of readers' book search,reducing the workload of Librarians' book inventory and Book shelving,and improving the accuracy of book utilization analysis;according to the demand analysis,the performance objectives of the system are determined,including the accuracy of book positioning 98%,the time of book storage?15 seconds,and the reaction time of book change?1.5 seconds.In order to achieve the goal of the system,the overall structure of the system is established,including equipment layer,network facilities layer and application layer,and the overall workflow of the system is analyzed.(2)According to the overall scheme,the hardware design scheme of the system is proposed,and the three key performances of detection accuracy,detection time and detection success rate are designed.Through the transmission network distribution and Book Geographic Information Architecture,the spatial level and corresponding relationship of book positioning are determined,and the intelligent bookshelf is designed from the structural and electrical aspects.The specially designed special-shaped antenna can change the magnetic field range,concentrate the magnetic field in the label pasting area,reduce the energy radiation of the easy to read parts,and improve the detection accuracy while ensuring the detection success rate.The fast conflict detection method using edge computing technology and initial screening plus fine search can reduce the network load,shorten the system response time,optimize the book conflict detection time,and improve the detection,efficiency by 33.8%compared with the conventional 16 slot conflict detection.The optimized labeling rule method can reduce the probability of label complete overlap by 91.6%,and improve the detection success rate.(3)The special software of book positioning system is designed.Based on the analysis of user roles and needs,the system architecture of the software is built,and the database is designed by analyzing the data business relationship and entity attributes;the bookshelf configuration,bookshelf grouping,book positioning and other functions are designed;the reader search navigation and librarian assistant interface are designed and implemented.In this paper,the software and hardware model is built,and the function and performance of the system are tested.The system indicators meet the research expectations.The test results show that the software and hardware design scheme can achieve the goal of book positioning,book retrieval and navigation,book accurate statistics,and meet the design expectations.The accuracy of this system is more than 98%.Compared with other systems,it can significantly improve the accuracy of book location,save readers' time to find books,reduce the workload of librarian book sorting,and improve the accuracy of variable book analysis.
