【摘要】：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。
[Abstract]:Real Time Kinematic (RTK) and total station are controlling surveying and topographic map surveying. Deformation monitoring and construction lofting are more and more widely used. In order to master the RTK and total station instrument in the above period of application, because of the inaccurate measurement of the height of the middle rod itself, the measurement accuracy is reduced. Based on the measurement principle of laser rangefinder, the integrated technology design idea of "laser rangefinder precision amplification device display screen" is adopted. A kind of high efficient alignment rod is designed, which is convenient for accurate height measurement. The results show that the 25% measurement precision can be effectively improved in the closed traverse ring and the attached traverse ring by using the integrated height measurement of the middle rod after the optimization design. And the time used is almost the same as that used in the traditional method when the centering rod is not used efficiently. It can be seen that, under the condition that the measuring time is invariant, the measurement accuracy can be improved effectively and the measurement efficiency can be improved by using the high-efficiency integrated alignment rod. To achieve the purpose of further improving the overall quality of the project.
