摘要
目前我国铁路精准放样主要采用GPS系统,而北斗系统在铁路领域应用较少。本文首先阐述北斗高精度定位技术的数据流程及原理,研究基于北斗高精度定位的接触网杆位测量系统,同时提出接触网杆位放样可视化操作,最后对北斗高精度定位技术和铁路专用电子地图生成等关键技术进行详细论述。
At present, the accurate lofting of domestic railway construction engineering is mainly depending on GPS system, with less application of Beidou navigation system. The paper illustrates firstly the data flows and principles of high precise positioning technology of Beidou navigation system, introduces the researches on OCS mast position measurement system based on Beidou high precise positioning technology for OCS mast measurement system, and describes in details the key technologies of high precise positioning technology and generation of railway dedicated electronic map.
