摘要控制网具有控制全局，防止误差累积以及提高测量精度的作用，以控制网为基础进行各项测绘工作。控制网分为平面控制网和高程控制网。平面控制测量是为了确定各个控制点的平面坐标，从而在测量平差基础理论下对测量数据进行一系列的整理、分析、计算和控制网精度评定工作。随着测绘科学技术和计算机技术的不断发展，可以根据控制网的平差规律，利用计算机语言进行编程，实现导线网平差的自动化。73885

Abstract Control network with control global, prevent the error accumulation and improve the accuracy of measurement, based on control network for the surveying and mapping work。 Control network is pided into plane control network and elevation control network。 Plane control measurement is to determine the plane coordinates of each control point, so as to carry out a series of finishing, analysis, calculation and control network accuracy evaluation of the measurement data in the basic theory of measurement。 With the continuous development of surveying and mapping science and technology and computer technology, can according to the law adjustment of control network, using computer programming language, realize the automation of wire net adjustment。
The purpose of this study is to solve the problem of adjustment of single node traverse network in surveying and Mapping Surveying。 The topic mainly studies the data structure of the traverse network, the calculation of the level difference and the accuracy of the evaluation, including data input, output mode and data management and preservation。Using Visual Basic 6。0 programming environment to the related content of program design, design achievement has realized the single node traverse net adjustment of automation and high precision。 Users can according to the actual need for data entry, so as to solve the actual problem of adjustment is calculated。
Key words：control network; Single node traverse network; Program design; Adjustment calculation
