摘　　要：将差分数据处理技术应用于智能型全站仪自动化变形监测系统,即设置已知基准点,求取观测点和基准点之间观测值与已知值的较差,计算单位改正数,进而求得改正值。经计算及实验,该方法对斜距、单向三角高差和水平方向观测值的改正效果较好,具有推广使用价值。The method of applying differential data processing technology to the intelligent total station automatic deformation monitoring system is to set a known reference point, obtain the difference between the observed value and the known value between the observation point and the reference point, and calculate the unit correction number, and then find the correction value. Through calculation and experiment, the method has better correction effect on slant range, one-way triangular height difference and horizontal direction observation value, and has popularization and use value.
