The invention discloses a train tail auxiliary positioning method and device, and the method comprises the steps: obtaining first train tail position data transmitted by a train head wireless communication unit, and temporarily storing the first train tail position data to a safety processor; the positioning module calculates and obtains reference train tail position data corresponding to the positioning module according to the sub-position data provided by the global satellite navigation unit and temporarily stores the reference train tail position data to the safety processor; the secure processor determines second train tail position data from the reference train tail position data; when the difference value between the first column tail position data and the second column tail position data is smaller than a set threshold value, the second column tail position data is determined as effective column tail position data; and synchronously sending the effective train tail position data to train head communication equipment and a ground control center. According to the scheme, the train tail positioning equipment is installed at the tail of the train, the positioning data are calculated through the train tail positioning equipment, and real-time continuous train tail auxiliary positioning data are autonomously provided in the environments of dynamic operation of the train, satellite signal failure and the like.

    本发明公开了一种列车尾部辅助定位方法和装置,其中所述方法,包括:获取列车头部无线通信单元发送的第一列尾位置数据并暂存至安全型处理器;定位模组依据全球卫星导航单元提供的子位置数据计算获得与定位模组对应的参考列尾位置数据并暂存至安全型处理器;安全型处理器从参考列尾位置数据中确定第二列尾位置数据;当第一列尾位置数据与第二列尾位置数据的差值小于设定阈值时,确定第二列尾位置数据为有效列尾位置数据;同步发送有效列尾位置数据至列车头部通信设备以及地面控制中心。本发明方案通过在列车尾部安装列尾定位设备,由列尾定位设备计算定位数据,在列车动态运行和卫星信号失效等环境下,实现自主提供实时连续列车尾部辅助定位数据。
