摘　　要：近年来随着测量技术迅速发展及AHCORS系统的建成投运,结合安徽省坐标转换七参数与全省似大地水准面精化模型,使得在安徽省内测量效率和精度大大提高。本文通过简述AHCORS系统的组成及原理,分析了其适用范围。利用AHCORS系统对已有控制点进行精度校核,结果表明,使用AHCORS系统测量得到的数据精度较高,能够直接用于变电站图根控制测量。并结合500 kV阜阳四变电站工程实例,提出使用AHCORS系统与全站仪相结合的方式进行地形测量,能够大大提高野外测量效率。In recent years,with the rapid development of surveying technology and the completion and operation of AHCORS system,the efficiency and accuracy of surveying in Anhui Province have been greatly improved by combining seven parameters of coordinate transformation with the provincial quasi-geoid refined model.This paper briefly describes the composition and principle of AHCORS system,and analyses its application scope.The accuracy of the existing control points is checked by using the AHCORS system.The results show that the datas obtained by using the AHCORS system are highly accurate and can be directly used in substation root control measurement.Combining with the engineering example of Fuyang No.4 substation of 500 kV,the method of combining AHCORS system with total station is put forward,which can greatly improve the efficiency of field survey.
