采用北斗精确定位技术监测输电线路杆塔基础位移

Monitor Displacement of Tower Base of Transmission Lines by Beidou Precise Positioning Technology

针对湖北所辖500 k V线路一基杆塔受地质影响而出现滑移,杆塔主材变形、倾斜度增加,横隔面交叉材向上弯曲拱起问题,采用北斗精确定位技术建立了输电线路地质灾害监测预警系统,对杆塔基础进行毫米级精度的全天候不间断在线监测,为线路运维抢修决策提供了直接参考依据。北斗精确定位系统采用载波相位差分技术进行数据解算,能够对缓慢微弱的准静态位移实现毫米级精度的定位,适用于输电线路杆塔的地质灾害监测。

In view of the 500 k V transmission tower slipped slowly, the main tower inclination de-formation, increase cross diaphragm material bend arch problem due to geological Influence in Hu-bei province, the Beidou precise positioning technology is applied to establish the monitoring andwarning system of geological disaster of transmission lines. The system could monitor the towerbase of millimeter accuracy in all-weather, which could provide the direct reference for the deci-sion of line operation and maintenance. The Beidou precise positioning system use Real Time Kine-matic(RTK) technology to process Beidou satellite positioning data. This method could monitor theslow and weak quasi-static displacement of millimeter accuracy. It is applicable to the monitor ofthe geological disasters of transmission lines.
