【摘要】：为了解决传统图书借阅形式带来的诸多不便,运用ZigBee技术构建了图书检索导航系统。将图书馆内放置无线定位节点作为参考节点,内置有ZigBee定位模块的手持终端作为盲节点,来构建一个ZigBee无线定位网络,在定位网络中计算出的盲节点坐标即为读者的位置。根据系统需求,从硬件和软件两方面设计了系统的各个模块,提出了一种改进的加权质心算法,用于手持终端的定位。通过Matlab对改进的加权质心算法进行了仿真实验,结果表明:改进的加权质心算法比质心算法、PDR-WCL算法精度更高,定位误差在1m以内。
[Abstract]:In order to solve the inconvenience caused by the traditional book borrowing form, a book retrieval navigation system is constructed by using ZigBee technology. The wireless location node is used as the reference node in the library and the handheld terminal with the ZigBee positioning module is used as the blind node to construct a ZigBee wireless location network. The coordinates of the blind node calculated in the location network are the reader's position. According to the requirement of the system, each module of the system is designed from both hardware and software, and an improved weighted centroid algorithm is proposed to locate the handheld terminal. The simulation results of the improved weighted centroid algorithm by Matlab show that the improved weighted centroid algorithm is more accurate than the centroid algorithm and the positioning error is less than 1m.
