在室内蓝牙定位系统中,蓝牙节点的部署问题对定位精度有较大影响,同时,部署方式的不同也决定了系统成本的高低。本文首先讨论了多种平面节点的部署方式,包含基于MATLAB的正方形网格的节点部署算法、正六边形部署、正四边形部署、随机部署等多种部署方式,然后从部署效率和部署成本等方面进行比较,最后考虑到室内定位的实际误差情况,提出了方形四点包含部署方式。该方式的部署成本相对正四边形和正六边形部署较高,但定位的精度提高了36.3%,将显著提升用户的体验。

In the indoor Bluetooth positioning system,the deployment problem of the Bluetooth node has a great influence on the positioning accuracy. At the same time,the difference of the deployment mode also determines the system cost. This paper first discusses the deployment of a variety of planar nodes,including MATLAB-based square grid node deployment algorithm,regular hexagonal deployment,regular quadrilateral deployment,random deployment and other deployment methods,and then from the aspects of deployment efficiency and deployment costs. For comparison,and finally considering the actual error of ...
