DGPS技术在铁路行业的应用

Application of DGPS Technology in Railway Industry

运行环境以及采集数据时的行业特点决定了铁路行业对位置信息高精准度的需求,分析终端接收卫星定位数据的技术原理,GPS数据达不到要求,采取差分技术手段,提出差分全球定位系统(DGPS),通过对GPS数据的差分来提高定位精准度。总结DGPS数据采集技术特点,并与当前传统勘测手段进行比较,考虑数据隐私、人员安全等因素,通过理论方案设计和试验验证,选取最符合铁路行业运行条件的实现方案,保证铁路部门采集数据的隐私性、时效性和准确性。

The operating environment and the industrial characteristics during the procedure of data collection jointly determine the strict requirement for high-precision position information of the railway industry.The technical principle of receiving satellite-positioning data by terminal was analyzed,and GPS data was found to be unable to meet the requirements.The deferential technology method was thus adopted and differential global positioning system(DGPS)was put forward to improve the positioning precision through the difference of GPS data.This paper summarized the characteristics of DGPS data collection technology,compared them with the current traditional survey methods,took data privacy,personnel safety,and other factors into consideration,and then selected the implementation plan that best meets the operation conditions of the railway industry through theoretical scheme design and experimental verification,so as to ensure the privacy,timeliness,and accuracy of data collected by the railway sector.
