摘　　要：引入北斗导航卫星技术,提出北斗铁路列车卫星定位与辅助预警系统,对列车进行准确定位,并根据铁路运行列车的运行位置进行相邻列车间距预警计算。当相邻列车间的距离达到预警条件时,提示司机和调度人员注意行车安全,防止列车追尾事故的发生。Based on the introduction of the BeiDou navigation satellite technology, the paper puts forward a BeiDou navigation satellite train positioning and warning system for realizing train precise positioning and calculating the warning distance between adjacent trains. When the distance between adjacent trains meets the warning condition, the system will prompt the driver and dispatching personnel to pay attention to the operational safety, in order to avoid any train collision accident.
