摘要
本文利用全站仪进行输电线悬挂点坐标非接触测量,根据测量得到的三维坐标,采用VisualC++6.0计算输电线应力、弧垂与长度以实现,由OpenGL完成输电线三维空间形态布局模拟。利用OpenGL的坐标变换、深度缓存、双缓冲等技术,可从多视角全方位观察输电线布局模拟效果,画面流畅,能够真实地显示输电线设计效果,避免设计错误的现场出现、降低了工程造价;同时替代人工快速计算相应档距的弧垂及线长,提高了工作效率、克服了人为误差。
In this paper,Total Station is used to measure the suspension point’s coordinate of transmission line in a non-contact way.Visual C＋＋ 6.0 work out the stress,sag and wire length of transmission line based on threedimensional coordinate,and then OpenGL completes the three-dimensional shape layout simulation of transmission line.The technology of coordinate transformation,depth buffer and double buffering provided by OpenGL makes it available to observe simulation effect from omni direction and multi-vision in smooth pictures.It can truly show the transmission line’ design effect,avoid the design errors committed on the actual site and reduce the construction cost;the system also replace the human to work out the sag and wire length of corresponding span promptly,thus improve the working efficiency and overcome artificial error.
