北斗卫星导航RTK定位技术在铁路通信铁塔监测中的应用

Application of Beidou Satellite Navigation RTK Positioning Technology in Railway Communication Tower Monitoring

通过自带基准站并利用北斗实时动态载波相位差分定位技术(Real-Time Kinematic,RTK)对铁路通信铁塔发生的水平位移、铁塔垂直度、塔基沉降进行连续不断测量和监控,解决以往铁塔监测系统误报、漏报率高、设备故障率高以及安装难度高、安装要求苛刻等施工难题,通过野外环境实验数据表明其精度满足中国铁路总公司发布的《铁路通信铁塔监测系统》(Q/CR851—2021)标准要求。

This article proposes a system that continuously measures and monitors the horizontal displacement,tower verticality and tower base settlement of railway communication towers by using built-in reference stations and Beidou real-time kinematic(RTK)carrier phase differential positioning technology,and solves the construction problems of the false alarms,high false alarm rates,high equipment failure rates and installation difficulties and strict installation requirements of previous tower monitoring systems.Field environmental experimental data shows that its accuracy meets the standard requirements of"Technical Conditions for Railway Communication Tower Monitoring Systems(QC/R 851—2021)"issued by China Railway Corporation.
