摘　　要：随着高校智慧化图书馆的建设和发展,室内定位技术在具有位置感知的智慧图书馆建设和管理中的作用日益重要。针对现有的基于WLAN的位置指纹定位技术在图书馆复杂环境下定位精度不高的问题,在考虑到高校接入IPv6网络的基础上,提出了基于WLAN的位置指纹定位技术和基于6Lo WPAN的WSN定位技术相互融合的定位技术。文章简要介绍了位置指纹结合6Lo WPAN定位技术的工作原理,从硬件和软件两个方面设计了基于位置指纹结合6Lo WPAN技术的图书馆智能定位系统的各个模块。基于此设计方案,实现了基于位置指纹和6Lo WPAN的智能定位系统。从系统测试可知,位置指纹结合6Lo WPAN定位技术比单一的位置指纹定位技术定位精度高。文章最后探讨了基于位置指纹结合6Lo WPAN的智能定位系统的发展前景,为高校图书馆建设智能定位系统提供借鉴。With the development of university intelligent libraries, the role of indoor positioning technology has become more prominent in the management of intelligent libraries with location sensing. To solve the problem of poor indoor positioning accuracy in a complicated library environment with WLAN- based location fingerprint positioning technology, this paper proposes a new positioning technology which integrates WLAN-based location fingerprint positioning technology with 6LoWPAN-based WSN positioning technology on the assumption of access to IPv6 network. This paper briefly introduces the working principle of location fingerprint combining 6LoWPAN-based positioning technology, and designs the new modules of library intelligent positioning system in terms of hardware and software. System testing reveals that, compared with the single location fingerprint technology, the integrated positioning system boasts a higher positioning accuracy. At the end of the paper, the development prospects of the system are discussed, providing reference for university libraries to construct library intelligent positioning system.
