摘要
在基于通信的列车控制(CBTC)领域中,列车定位是一项重要技术。本文利用全球定位系统(GPS)、嵌入式系统、嵌入式数据库等技术,根据实测GPS数据,针对数字轨道地图获取、处理和管理轨道数据等内容展开研究。详细介绍用ARM7+uClinux+SQLite组合构建数字轨道地图数据管理的嵌入式平台软硬件设计方法和具体实现步骤,为基于嵌入式数字轨道地图的列车定位研究提供一个基础平台。
In the research area of Communication Based on Train Control（CBTC）,train positioning was an important technology.In this paper,using GPS,Embedded System and embedded database,based on the measured data of GPS,aimed at the obtaining and processing of digital track map,as well as the management of track data,the research was carried out.The detailed procedures of establishing the platform by ARM7,uClinux and SQLite were introduced by using the real GPS track data,which provided a solid foundation for the train positioning research based on DTM.
