摘要:
为了检测控制激光扫平仪垂直扫平面铅垂精度,对激光扫平仪垂直扫平误差进行了分析。利用球面三角形的正弦和余弦定理,推导了激光扫平仪垂直扫平面倾斜误差计算公式,建立了锥角误差和倾斜误差几何叠加的激光扫平仪垂直扫平误差数学模型,搭建了基于水平轴线对称布局的双光管专用检测装置,设计了先分项测量、后按数学模型叠加的激光扫平仪垂直扫平误差测量方案,并进行了测量试验验证。结果表明:采用所提方案获得的仪器不同姿态下垂直扫平误差测量结果的最大差值不超过6. 3″,优于传统方案的16. 5″,证明所设计的测量方案可行,构建的数学模型准确可靠。
Abstract:
In order to test the vertical accuracy of the vertical level plane about the rotating laser, the vertical level error of the laser level was analyzed. Using the sine and cosine theorems of spherical triangles, the calculation formula of total deviation of the rotating axis from the axis of the rotating laser was deduced. The mathematical model of the deflective deviation with the total deviation of the rotating axis from the axis was established. A special test device with double light pipes based on horizontal axis symmetry was built, and a scheme was designed to first measure the error component separately and then synthesize the vertical error, and experiments were carried out to verify it. The results showed that the maximum difference was no more than 6.3" obtained in our scheme in different instrument poses, which was better than the maximum difference of 16.5" in the traditional scheme, which proved that the designed scheme was technically feasible, and the mathematical model was accurate and reliable.
