隧洞施工人员U-Beacon定位系统设计与开发
摘要
Abstract
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.关键词
