摘　　要：在CTCS-3级和ETCS-2级列控系统中,车载设备基于参考应答器确定列车位置和运行方向,向无线闭塞中心报告列车位置,无线闭塞中心根据列车的位置向列车发送行车许可等控车信息,共同保障高速铁路列车安全高效运行。介绍基于参考应答器计算列车位置和方向的基本概念、基本原理和计算方法;阐述车载设备位置报告中的位置和方向的基本概念;分析不同场景下列车位置和方向的状态转换关系;分析和介绍通用的列车位置和方向的计算方法。In CTCS-3 and ETCS-2,on-board equipment determines the train position and running direction based on the last relevant balise group,and reports the train position to Radio Block Center(RBC).RBC sends train control information such as movement authority to the train according to the train position,so as to jointly ensure the safe and efficient operation of the high-speed trains.This paper introduces the basic concept,basic principle and method of calculating train position and direction based on the last relevant balise group,expounds the basic concepts of location and direction in the on-board equipment location report,analyzes the state transition relation of train position and direction in diff erent scenarios,and analyzes and introduces the general calculation method of train position and direction.
