The invention provides an early warning method for railway driving safety protection. The early warning method comprises the steps that S1, an early warning target in front of a train is obtained, and the early warning type is judged; s2, on the basis of a plurality of key time points on a path from the train to the early warning target, the path is divided into a plurality of areas in sequence in the direction from the train to the target, and each area has a corresponding early warning level; s3, setting a corresponding danger coefficient for the target based on the early warning type of the target, and calculating the early warning priority of the target based on the early warning level of the region where the target is located and the danger coefficient of the target; s4, calculating early warning risk values of the targets based on the early warning priorities of the targets and the relative speeds between the train and the targets, selecting the early warning risk values greater than zero, sorting the early warning risk values, and sequentially sending early warning information corresponding to the early warning targets to the vehicle-mounted early warning terminals based on a sorting result; and the train adjusts the speed of the train and/or performs whistling warning based on the received early warning information.
本发明提供一种用于铁路行车安全防护的预警方法,包含步骤:S1、获取列车前方的预警目标并判断预警类型;S2、基于从列车到预警目标的路径上的多个关键时间点,沿着从列车至目标的方向,将所述路径依序划分为多个区域,各区域具有对应的预警等级;S3、基于目标的预警类型为目标设置对应的危险系数,基于目标所在区域的预警等级、目标的危险系数计算目标的预警优先级;S4、基于目标的预警优先级和列车与目标之间的相对速度,计算目标的预警风险值,选取大于零的预警风险值并进行排序,基于排序结果依序向车载预警终端发送对应预警目标的预警信息;列车基于接收的所述预警信息调整车速和/或进行鸣笛警告。
