【摘要】：测量工作渗透在国家建设的诸多领域，测量数据处理作为其核心内容显得尤为重要。当前，测量数据处理软件已得到广泛应用，保证了测量计算的准确性，不仅为工程设计、施工和安全运营提供了可靠保证，还大大提高了工作效率。但是已有的软件均为单机版，随着网络技术的飞速发展，开发测量数据处理的网络平台成为一个新的发展方向。为此本文进行了网络版测量数据处理系统的研究与应用。首先，指出传统Web技术在系统研发中存在不足，而RIA则能很好地解决此问题。通过比较分析当前几种主流的RIA技术，从各自的技术特点、优势及掌握的难易程度等出发，选择Silverlight作为实现网络化的关键技术，并对Silverlight的技术架构、界面模型、数据模型以及数据访问和网络通信技术进行了深入研究。其次，介绍了系统研发所使用的测量数据处理的数学模型，主要有间接平差模型、秩亏网平差模型、粗差探测方法、坐标转换以及图幅计算等。然后，在确定了系统实现技术和数学模型的基础上，选择合适的系统开发平台并对系统的功能、数据库及数据输入输出方式进行设计。其中平差算法程序设计、控制网图形显示、误差椭圆的绘制以及Bing Maps地图服务二次开发是研究的难点和重点。最后，将所研发的系统应用到具体工程项目中，并与常用软件的处理结果进行比较，，验证系统数据处理的可靠性。
[Abstract]:Measurement work permeates in many fields of national construction, measurement data processing as its core content is particularly important.At present, measurement data processing software has been widely used to ensure the accuracy of measurement calculation. It not only provides a reliable guarantee for engineering design, construction and safe operation, but also greatly improves the working efficiency.With the rapid development of network technology, the development of measurement data processing network platform has become a new development direction.Therefore, this paper carries on the research and the application of the network version measurement data processing system.Firstly, it is pointed out that the traditional Web technology is insufficient in system research and development, and RIA can solve this problem well.By comparing and analyzing several mainstream RIA technologies, this paper selects Silverlight as the key technology to realize the network from the point of view of their technical characteristics, advantages and the degree of difficulty in mastering, and gives the technical framework and interface model of Silverlight.The data model, data access and network communication technology are deeply studied.Secondly, the mathematical model of measurement data processing used in system development is introduced, including indirect adjustment model, rank deficit network adjustment model, gross error detection method, coordinate transformation and map calculation.Then, on the basis of determining the realization technology and mathematical model of the system, the appropriate system development platform is selected and the system functions, database and data input and output modes are designed.Among them, the programming of adjustment algorithm, the graphic display of control network, the drawing of error ellipse and the secondary development of Bing Maps map service are the difficulties and emphases of the research.Finally, the developed system is applied to the specific project, and compared with the results of common software to verify the reliability of the system data processing.
