摘要:
针对电力北斗安全应用、自动驾驶导航等应用场景对室内外一体化无缝定位的迫切需求,设计了一种将UWB与GNSS结合的一体化无缝定位系统。通过将UWB标签与小型化GNSS模块集成到手持智能设备上形成一体化定位终端,服务器软件对卫导结果与超宽带定位结果进行融合,输出连续定位结果。实验结果表明,该系统可以实现人员的室内外一体化无缝定位,室内环境下的静态定位精度小于10cm,该系统已应用于大型发电厂和变电站的人员安全防护管理项目。

Abstract:
Aiming at the urgent need for seamless positioning in application scenarios such as electric power BeiDou safety application and autonomous driving navigation, this paper designs a UWB/GNSS system for integrated seamless positioning. By integrating UWB tags and miniatur-ized GNSS modules into handheld smart devices to form an integrated positioning terminal, the service platform software integrates RTK results and UWB results to provide a combined solution. Experimental results show that the system can realize seamless positioning indoors and outdoors, and the static positioning accuracy in an indoor environmentis is less than 10 cm. The system has been used in personnel safety protection management projects in large power plants and substations.
Key words:  Indoor positioning  UWB  Safety protection
