摘　　要：找书难一直是困扰图书馆用户的一大难题。现在基于WIFI、Beacon、GPS、ZigBee等技术的室内导航系统由于定位精度低,难以实现书架内部的导航,致使无法大面积推广。本系统利用图书馆已有RFID技术获取图书的位置信息,通过C/S网络架构和RS485串行通信技术,把图书的位置信息分级传送给单片机系统,单片机系统再引导用户到达图书所在位置,实现精确到书架层的立体式图书定位导航。通过这套系统用户可以方便、准确、快捷的找到所需图书,而不需要图书分类法的帮助。The difficulty of finding books has always been a big problem for library users.Now navigation systems based on WIFI,Beacon,GPS,ZigBee and other technologies lack accuracy in navigating to bookshelves,which limit their wide use.In this article,with the help of existing RFID positioning technology in the library to get the location information of books,and by using the C/S network architecture and RS485 serial communication technology,the location information of books are transmitted to the MCU hierarchically.The MCU guides users to the location of books and realizes the three-dimensional book positioning and navigation accurately to the shelf level.By this system,users can easily find required books accurately and conveniently without the help of book classification.
