摘要
目前国内各大高校图书馆由于馆内面积大,书籍分布分散,普遍存在人工查询低效和找书困难的问题。对此,提出了利用无线技术自动导航系统取代原来的人工查询系统的解决方案。本系统利用蓝牙定位技术,用蓝牙信号发射点全面覆盖图书馆,采用改进的TOA算法,并综合运用Web以及数据库作为后台支持,实现了读者使用手持设备搜索书籍并自动导航到书籍所在位置的一体化功能。通过实地测试,系统可以在一定程度上辅助读者,提高寻书效率。
Owning to the large area of library and decentralized distribution of books, the problems of low efficiency by mankind and difficulty in finding out where the book is, exist in most domestic library of universities. Therefore, a bluetooth auto - navigation system for library to replace the original artificial query system is proposed. This auto - navigation system uses bluetooth positioning technology,and bluetooth signal transmission points comprehensively coverage Library. Meanwhile, the adoption of improved TOA algorithm,and the integrated use of Web and database as a back -office support realizes the integrative function for readers to search books with handheld devices and automatically navigation. Through tests, the system can assist readers to improve the efficiency of searching to a certain extend.
