基于物联网的隧道多功能UWB定位系统

Tunnel Multifunctional UWB Positioning System Based on the Internet of Things

电缆隧道通讯信号弱、有害气体、高压高电等不利因素会影响电缆隧道内运维人员的生命安全。UWB技术可作为传输技术应用于定位系统,具有定位精度高、抗多径干扰能力强、低功耗等优点。在隧道内按照合理的布局间隔安装带有AP功能的UWB定位基站,通过物联网技术实现定位、有毒气体检测、验电、照明等功能,可提高隧道运维的安全。

Adverse factors such as weak communication signals,harmful gases,and high voltage and electricity in cable tunnels can affect the safety of operation and maintenance personnel inside the tunnel.UWB technology can be applied as a transmission technology in positioning systems,with advantages such as high positioning accuracy,strong resistance to multipath interference,and low power consumption.This system installs UWB positioning base stations with AP function at reasonable layout intervals in the tunnel,achieving functions such as positioning,toxic gas detection,electricity inspection,lighting,etc.through IoT technology,which is of great significance for improving the safety of tunnel operation and maintenance.
