摘要
为了有效解决各大图书馆管理过程中存在的图书乱架严重、图书位置不准确、查找图书困难等问题,设计一种基于超高频射频识别技术的智能书架图书管理系统。对信号强度值进行高斯滤波处理,改进LANDMARC室内定位算法,采用阅读器驱动和管理员驱动两种定位策略相结合的方式,实现了图书的实时精确定位。在LabVIEW环境下设计了上位机管理系统,利用MySQL数据库建立数据表,对用户和图书信息进行联合管理,实现了用户管理、图书检索、图书定位、错架整理等功能。系统测试表明,智能书架可以准确定位在架图书,并生成错架图书列表,为管理员的盘点工作提供了方便。与手持式和推车式盘点设备相比,该系统大大提高了图书盘点效率,实现了无人参与式管理模式,并及时更新错架图书的馆藏位置,有效提升了图书馆服务水平。
In order to effectively solve the problems of serious book disorder,inaccurate book position,and difficulty in finding books in the management process of major libraries,an intelligent bookshelf book management system based on UHF RFID is studied and designed in this paper.The signal strength value is processed by Gaussian filtering.The LANDMARC indoor positioning algorithm is improved.A mode of combining reader⁃driven positioning strategy with administrator⁃driven positioning strategy is adopted to achieve real⁃time accurate positioning of books.The host computer management system is designed in the LabVIEW environment.The MySQL database is used to establish data tables to jointly manage user and book information.The functions of user management,book retrieval,book positioning,and wrong rack sorting are realized.The system test result shows that the intelligent bookshelf can accurately locate the books in the bookshelf and generate a list of books in the wrong bookshelves,which provides convenience for the administrator's inventory work.In comparison with hand⁃held and handcart⁃type inventory devices,the system greatly improves the efficiency of book inventory,realizes the unattended management mode,and can timely update the collection location of the wrong books,which effectively improves the service level of libraries.
