The invention provides a train safety protection method, device and system, and relates to the technical field of rail transit. The method comprises the following steps of: calculating a first relative running distance calculation formula of a following train and a pilot train in a relative traction removal stage, a second relative running distance calculation formula in a relative braking establishment stage and a third relative running distance calculation formula in a relative maximum braking stage; determining a safe relative speed between the following train and the pilot train; and determining the safety limiting speed of the following train based on the safety relative speed and the current running speed of the pilot train. The running speed of the pilot train is considered when the safety limiting speed of the following train is determined, the soft wall collision safety protection principle is met, the safety protection distance between the trains can be shortened, the safety relative speed between the following train and the pilot train is considered when the safety limiting speed of the following train is determined, and the safety protection distance between the trains can be shortened. And safe operation of trains in the virtual marshalling can be guaranteed.

    本发明提供一种列车安全防护方法、装置及系统,涉及轨道交通技术领域,所述方法包括:基于跟随列车和领航列车在相对牵引切除阶段的第一相对走行距离计算公式、在相对制动建立阶段的第二相对走行距离计算公式和在相对最大制动阶段的第三相对走行距离计算公式,确定跟随列车和领航列车之间的安全相对速度;基于安全相对速度和领航列车当前的运行速度,确定跟随列车的安全限制速度。本发明在确定跟随列车的安全限制速度时考虑了领航列车的运行速度,满足撞软墙安全防护原则,能够缩短列车之间的安全防护距离,而且在确定跟随列车的安全限制速度时考虑了跟随列车和领航列车之间的安全相对速度,可以保障虚拟编组内部列车的安全运行。
