隧洞施工人员U-Beacon定位系统设计与开发

针对传统UWB定位技术在大范围隧洞内人员定位中存在布线成本高、施工周期长、风险高的问题,结合UWB定位技术和Beacon技术,提出一种基于U-Beacon的隧洞内人员定位系统,并针对隧洞复杂施工场景进行定位系统网络拓扑结构设计、U-Beacon定位系统部署方案设计及硬件电路设计。以施工人员佩戴便携式胸卡标签方式,提高系统易用性。采用TOA定位算法和Sage-husa自适应卡尔曼滤波算法对UWB测距数据进行定位和降噪处理,实现对洞室复杂施工环境的精准定位。实验结果表明,基于U-Beacon的人员定位系统大大降低施工成本,降低施工风险,同时Sage-husa自适应滤波算法在提高隧洞内定位精度和鲁棒性方面有很大的提升。

Aiming at the problems of high wiring cost,long construction period and high risk of traditional UWB positioning technology in large-scale tunnel,combined with UWB positioning technology and Beacon technology,a tunnel personnel positioning system based on U-Beacon is proposed.Aiming at the complex construction scene of the tunnel,the positioning system network topology design,U-Beacon positioning system deployment scheme design and hardware circuit design are carried out.The construction staff wear portable badge tags to improve the ease of use of the system.TOA positioning algorithm and Sage-husa adaptive Kalman filter algorithm are used to locate and reduce noise of UWB ranging data to achieve accurate positioning of the complex construction environment of the cavern.The experimental results show that the personnel positioning system based on U-Beacon greatly reduces the construction cost and construction risk,and the Sage-husa adaptive filtering algorithm has greatly improved the positioning accuracy and robustness in the tunnel.
