Research on efficient mode of measu re ment for railway and accu racy analysis
摘要
Abstract
In this paper,an improved mode of measurement for railway was proposed based on existing inefficient mode.The efficiency of measurement for railway was improved by changing the position of setting position to re-duce times of setting position in the improved mode.The accuracy of measurement for both modes was the same through the analysis of precision.The results show that,the accuracy of the adjustment of the elevation and the horizontal plane is mainly affected by the distance and pitch angle.Thereinto,the accuracy of the adjustment of the elevation is significantly influenced by the pitch angle.However,the impact of horizontal angle has a relatively small effect on the accuracy of the adjustment of the horizontal plane and elevation.Finally,it can be found that minimizing the height difference between the total station and prism on track automatic detection system can largely reduce measurement errors on the elevation adjustment amount in the actual measurement process.关键词
