【摘要】：合肥光源升级改造工程一级和二级控制网的建立是基于LeicaTDA5005全站仪和激光跟踪仪，合肥光源的磁铁点位精度达到微米级，其高精度的要求已达到计量学的精度，即用精密工程测量学的方法，用高精度的现代仪器，达到计量学的精度指标；合肥光源升级改造工程的准直测量首先必须建立高精度的控制网，再通过控制网对磁铁点位进行定位和调试。而本文主要是对一级和二级控制网进行施测方案设计、模拟计算并且通过实际测量数据进行平差计算，从而建立稳定、合理和高精度的控制网。本论文的主要内容如下： 1、针对合肥光源进行简单的介绍，并且阐述了合肥光源升级改造的必要性；同时对合肥光源升级改造工程的准直测量进行概述。 2、阐述了合肥光源升级改造工程建立一级和二级控制网的目的，对一级和二级控制网进行方案设计、精度分析和模拟计算。 3、介绍了合肥光源升级改造工程一级控制网的所用仪器和实测过程，并根据一级网的实测数据进行平差计算和精度评估。 4、介绍了合肥光源改造工程二级控制网的实测过程和施测难点，结合激光跟踪仪测量数据采用Spatial Analyzer（SA）软件的统一空间测量网络法（Unified Spatial Metrology Network，USMN）和三维网平差法进行数据处理，并对两种方法的数据处理结果进行对比分析，，从而对二级控制网进行精度评估。
[Abstract]:The establishment of primary and secondary control network of Hefei Light Source upgrading Project is based on LeicaTDA5005 total station instrument and laser tracker. The precision of magnetic spot position of Hefei light source reaches micron level, and its high precision requirement has reached metrology precision. That is to say, the precision index of metrology is achieved by means of precision engineering surveying method and modern instrument with high precision, and the collimation measurement of Hefei light source upgrading project must first establish a high-precision control network. Then the magnet spot is located and debugged through the control network. In this paper, the primary and secondary control networks are designed, simulated and adjusted through the actual measurement data, thus the stability is established. The main contents of this paper are as follows:. 1. The light source of Hefei is introduced briefly, and the necessity of upgrading the light source in Hefei is expounded. At the same time, the collimation measurement of the upgrading project of light source in Hefei is summarized. 2. The purpose of establishing primary and secondary control networks in Hefei Light Source upgrading Project is expounded. The scheme design, precision analysis and simulation calculation of primary and secondary control networks are carried out. 3. The instrument used in the primary control network of Hefei Light Source upgrading Project and the measurement process are introduced, and the adjustment calculation and accuracy evaluation are carried out according to the measured data of the first class light source. 4. The measurement process and difficulties of the secondary control network of Hefei Light Source Reconstruction Project are introduced. The unified spatial measurement network method Unified Spatial Metrology Network (USMN) and the three-dimensional network adjustment method are used to process the data of laser tracker using Spatial Analyzer-SAsoftware. The data processing results of the two methods are compared and analyzed so as to evaluate the accuracy of the two-level control network.
