摘要
系统研究了列车运行控制系统的专用数据库,构建了数据库的数据模型与数学拓扑模型,根据铁路运输的特点,给出铁路轨道定位领域的自适应定位匹配算法,将铁路轨道分为直线和曲线两个部分,采用基于移动距离窗的定位匹配算法实现了实时、精确和快速的定位匹配.在北京局三家店调车场进行了实验,证明本文研究的专用数据库在列车定位领域具有重要的实用价值.
Studied a special database based on CTCS-Low Cost,the data model and mathematical topological model of the database are built in detailed.According to the characteristics of the field of rail transport,the adaptive correlation matching location algorithm in the field of railway track position is proposed,the railway track is divided into straight lines and curves.Using correlation matching location algorithm based on moving distance window,the real-time,accurate and fast positioning match are realized.Finally,the results shown in this paper that the study of a special database has the important research and practical value through field trial tests in Sanjiadian marshalling yard of Beijing.
