The invention discloses an automatic train protection method for a maglev train. The method specifically comprises the steps of calculating the speed and the position of a traction removal point and calculating the speed and the position of an emergency braking application point. Searching a driving route map of an emergency braking applying point, judging whether the train tail to the applied EB is overspeed or not, and applying emergency braking when judging that the train tail is overspeed; then, searching for a driving route map, searching for a limiting point of the train from the EB applying position to the train authority point, judging whether the train is overspeed from the EB applying position to the train authority point or not according to the limiting energy of the limiting point, and if the train is overspeed, triggering emergency braking to ensure safe operation of the train. The method starts from the speed and the position of the traction resection point, sequentially obtains the conditions capable of judging the overspeed, is small in calculation amount, can effectively reduce ATP online calculation, is high in safety, and is especially suitable for automatic protection of the magnetically levitated train.

    本发明公开了一种用于磁悬浮列车的列车自动防护方法,具体通过计算牵引切除点的速度、位置,计算紧急制动施加点的速度、位置步骤;搜索到紧急制动施加点的行驶线路地图,判断列车车尾到施加EB是否超速,判断为超速时,则施加紧急制动;然后完成行驶线路地图的搜索,搜索列车从施加EB处到列车授权点的限制点,根据限制点的限制能量判断列车从施加EB处到列车授权点是否超速步骤,如果超速则应触发紧急制动,确保列车的安全运行。本发明从牵引切除点的速度、位置出发,依次获得可以判断超速的条件,计算量小,可有效减少ATP在线计算,安全性高,特别适用于磁悬浮列车的自动防护。
