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.
Based on the characteristics of railway transportation, an adaptive positioning and matching algorithm is proposed for the field of railway track locating. The railway track is divided into straight line and curve two In this paper, a real-time, accurate and fast positioning and matching algorithm based on moving distance window is implemented in this paper.Experiments are carried out in Shijiandian yard of Beijing Bureau, which proves that the special database studied in this paper has important practical value in the field of train positioning.
