GPS -RTK 在高压输电线路工程中的应用

摘要

In survey project of high voltage transmission line , due to effect of vegetations , the indivisibility condition is very poor;conventional surveying method results in not only a high cost , but also a long construction period and high surveying workload , there-fore it is difficult to ensure the restored line to be in consistence with the original straight line .With the aid of GPS ( Global Positioning System) technology, survey project of high voltage transmission line can be accomplished conveniently , swiftly, and accurately.The real-time dynamic measurement of RTK ( Real Time Kinematic ) intelligent positioning system discussed in this paper is characterized by its functions of calculating relative relationships among points , lines and surfaces as well as the function of visual graphical display , and is able to accomplish construction survey , record, as well as high intelligent and integration in calculation .Compared with tradi-tional surveying techniques , it is free from constraints of visual conditions , and can be applied to long distance , while maintaining high speed and high precision .In general, real-time dynamic measurement of RTK intelligent positioning system can significantly improve the production efficiency in engineering applications .%在高压输电线路工程测量中，由于受植被影响，通视条件极差；常规测量方法不但赔偿费用高，而且工期长，测量工作量大，很难保证恢复后的直线与原直线一致。随着全球定位系统GPS （ Global Positioning System ）的广泛应用，可借助GPS定位技术方便、快速、准确地进行测量。本文论述的实时动态测量RTK （ Real Time Kine2 matic）智能定位系统，具有点、线、面之间相对关系的计算功能及直观的图形显示功能，实现了施工测量、记录、计算的高度智能化、一体化；与传统的测量技术相比，不受通视条件的限制，测量的距离远、速度快、精度高；在工程应用中可以显著地提高生产效率。
