基于Visual Basic的导线平差程序设计

摘要

In order to solve the problem of processing lead control measurement data,the integrated environ-ment of Visual Basic 6.0 is used to develop traverse adjustment program. The program can calculate the ap-proximate coordinates of wire,calculate the error equation coefficient,calculate the adjustment values and evaluate the accuracy,automatically draw the error ellipse and wire sketch,and has the functions of data input, output mode,data storage and management. The measurement data is used for adjustment calculation by de-signed program and commerical South adjustment easy 2005 software,the accuracy and practicability of de-signed program are verified to ensure the reliability of data.%为了解决控制测量中导线的数据处理问题，采用Visual Basic 6.0的集成环境开发了导线平差程序，可以实现导线的近似坐标计算、误差方程系数计算、法方程的组成与解算、平差值计算及精度评定、导线略图和误差椭圆的自动绘制，以及数据录入、输出方式、数据存储与管理等功能。将本程序与商用南方平差易2005软件分别对校园导线测量数据进行平差计算及分析，验证了本程序的准确性及实用性，保证了数据成果的真实可靠。
