| 摘 要： | 为了设计一套高精度、高实时性、操作简单的室内定位系统,该系统采用DW1000芯片设计制作了UWB定位硬件板;以node.js为基础,使用htm15、css3和js搭建了web界面;使用socket.io技术实现了前后端的双向实时通信。为了保证定位精度,采用双边双向测距方法来测量距离,用双曲线模型定位算法来解析定位结果。对整个定位平台进行了实验测试,测试结果表明该平台运行稳定,web界面能实时清晰地显示标签位置,并且标签的定点精度在10 cm左右,动点精度在20 cm左右。

| Abstract: | This paper aims to design an indoor positioning system with high precision,high real-time and simple operations.The system first uses DW1000 chip to design and manufacture the UWB positioning hardware board,establishes web interface with HTML5,CSS3 and JS based on node.js,and uses socket.io technology to realize the two-way real-time communication between the front and back ends.To ensure the positioning accuracy,this paper adopts the double-sided two-way ranging method to measure the distance,and uses the hyperbolic model positioning algorithm to calculate the positioning result.Finally,the experimental test is performed on the whole positioning platform.The results show that the platform runs stably and the web interface can clearly display the label position in real time.The fixed-point accuracy of the label is 10 cm and the accuracy of the moving point is 20 cm. |
