摘要
当前,城市轨道交通为满足大运量的需求,对列车运行间隔要求越来越高,即列车自动控制系统对列车的定位必须更加精确可靠,以保证小间隔的列车安全运行要求。介绍了列车测速和列车定位的基本原理,从算法原理入手分析了列车速度不确定性和位置不确定性的产生原因以及计算方法,以供列车精确定位参考。
Currently, to satisfy the needs of large capacity,demands for urban rail transit operation interval become higher and higher,which means train positioning of the automatic train control system（ATC）must be more accurate and reliable to ensure the requirements of small operation intervals and safety. In this paper, the basic principle of train velocity measurement and train positioning is introduced,then the causes of train velocity and position uncertainties are analyzed,calculation methods of train position uncertainty are provided.
