新型压力管道绘制技术的研究

Research on New Pressure Pipe Drawing Technology

针对目前压力管道单线图存在的一些问题,如无法精确提供管道之间的相关位置和无法消除粗大误差对坐标系转换的影响,提出了一种基于空间直角坐标系转换的新型压力管道绘制方法,减少矩阵解算转换参数的频繁性并充分利用了可靠数据。采用抗差估计,减小个别公共点粗大误差对坐标转换参数的影响。结合模拟点的数据,验证了所提方法的可行性与有效性。该方法具有工程应用价值。

Aiming at the problems of current single-line diagrams of pressure pipelines,such as the inability to accurately provide the relevant positions between pipelines and the inability to eliminate the effect of gross errors on coordinate system conversion,a new method for drawing pressure pipelines was proposed based on the transformation of spatial rectangular coordinate system to reduces the frequency of matrix parameters transformation and utilize the reliable data fully.The robust estimation was used to reduce the influence of the coarse error of individual common points on the coordinate conversion parameters.The feasibility and effectiveness of the proposed method were verified by using the data from simulation points.This method has engineering application value.
