备注

由于实时动态差分法测量(Real Time Kinematic,简称RTK)和全站仪在控制测量、地形图测量、变形监测及施工放样中的使用越来越广泛。为掌握RTK和全站仪在上述应用期间由于对中杆本身高度测量不准确而造成测量精度的降低,进而影响到整体工程质量。以工程测量为背景,基于激光测距仪量测原理,通过采用“激光测距仪+精度放大装置+显示屏幕”的集成技术设计思想,设计出了一种高效的便于精确测量高度的对中杆。结果 表明:采用优化设计后的集成化对中杆进行高度量测,在闭合导线环和附合导线环中,可有效提高25%测量精度,而所用时间与传统不用高效对中杆时所用时间几乎相同。由此可见,在测量时间不变的情况下,采用高效集成化对中杆可以有效提高量测精度的同时提高了测量效率,达到进一步提高工程整体质量的目的

Because the RTK and total station were widely used more and morein control surveying,topographic map surveying,deformation monitoring and construction lofting.In order to master the plumbing pole of the RTK and total station that itself height measurement is not accurate causes the accuracy of the measurement reduce and then affect the quality of the overall project during the above project.Based on engineering survey and measurement principle of laser range finder,this paper uses integrated technology design including Laser rangefinder,precision amplifier and display screen,designs a plumbing pole with highly efficient and accurate measurement for height.The results showed that using the integrated plumbing pole after optimal design,can improve the measurement accuracy by25%,the time used is almost the same as the traditional usedtime in the closed traverse loop and connecting traverse.Therefore,using the plumbing pole with highly efficient and integrate can improve the measurement accuracy and the measurement efficiency to further improve the quality of the overall project in the situation of measurement time invariant.
