三距离交会法在输电线路测量中的应用

Application of triple distance inter section method in transmission line measurement

针对输电线路测量中,不能直接精确测定钢管杆中心坐标的问题。提出了使用三距离交会的测量方法,以及利用网络RTK配合手持电子测距仪,快速测得钢管杆附近三个点的坐标以及相应距离。针对不同观测数据编写了相应的VB程序,提高了工作效率。

For transmission line measurements,the coordinates of steel pole center cannot be directly measured accurately.This paper proposes the use of triple distance inter section method,and the use of handheld electronic range finder with network RTK,the coordinates of three points and the corresponding distance is measured near the steel pole.Corresponding VB program is prepared for different observation data,which has greatly improved work efficiency.
