基于GNSS的铁路勘测设计数字化采集系统设计

Design of GNSS-based Digital Acquisition System for RailwaySurvey and Design

本文结合铁路勘测设计实际需求,提出基于GNSS的铁路勘测设计数字化采集系统,包括中线测量、断面测量、水文测量、单点测量、既有线测量等。并从系统框架设计、功能设计等方面进行了详细阐述。系统利用移动设备、北斗导航、移动计算、CORS系统、GNSS RTK等技术资源,实现CAD地形图实时导航引导外业测量工作,满足铁路勘测设计工作要求,通过对移动设备功能进行精简和完善,确保系统贴合铁路勘测设计实际需求。

Combining with the actual demand of railway survey and design,this paper proposes a GNSS-based digital acquisition system for this purpose,including centerline survey,section survey,hydrological survey,single point survey,existing line survey,and so on.Then the design of the system framework and function is detailed.For this system,technical resources including mobile equipment,BeiDou Navigation Satellite System,mobile computing,CORS,and GNSS RTK are used to realize real-time navigation of CAD topographic map to guide the field survey and meet the requirements of railway survey and design.Then the functions of mobile equipment are streamlined and improved to ensure that the system meets the actual needs of railway survey and design.
