【摘要】：由于實(shí)時(shí)動(dòng)態(tài)差分法測(cè)量(Real Time Kinematic,簡(jiǎn)稱RTK)和全站儀在控制測(cè)量、地形圖測(cè)量、變形監(jiān)測(cè)及施工放樣中的使用越來(lái)越廣泛。為掌握RTK和全站儀在上述應(yīng)用期間由于對(duì)中桿本身高度測(cè)量不準(zhǔn)確而造成測(cè)量精度的降低,進(jìn)而影響到整體工程質(zhì)量。以工程測(cè)量為背景,基于激光測(cè)距儀量測(cè)原理,通過(guò)采用"激光測(cè)距儀+精度放大裝置+顯示屏幕"的集成技術(shù)設(shè)計(jì)思想,設(shè)計(jì)出了一種高效的便于精確測(cè)量高度的對(duì)中桿。結(jié)果表明:采用優(yōu)化設(shè)計(jì)后的集成化對(duì)中桿進(jìn)行高度量測(cè),在閉合導(dǎo)線環(huán)和附合導(dǎo)線環(huán)中,可有效提高25%測(cè)量精度,而所用時(shí)間與傳統(tǒng)不用高效對(duì)中桿時(shí)所用時(shí)間幾乎相同。由此可見(jiàn),在測(cè)量時(shí)間不變的情況下,采用高效集成化對(duì)中桿可以有效提高量測(cè)精度的同時(shí)提高了測(cè)量效率,達(dá)到進(jìn)一步提高工程整體質(zhì)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.
