The invention provides a CBTC (Communication Based Train Control) train section degradation protection method and device, and the method comprises the steps: determining the current position of a train according to the track offset of a transponder through which the train passes under the condition that the train has a signal fault and loses positioning; in the running direction of the train, starting route searching from the current position of the train until the position of an opposite turnout is searched; wherein the running direction of the train is obtained before the train breaks down; and taking the route between the current position and the opposite turnout position as autonomous movement authorization, and calculating a first protection curve of the train according to the route of the autonomous movement authorization. According to the method, the train runs safely under the protection of the vehicle-mounted signal equipment after being degraded in the section, the running speed of the train is increased, the influence on the operation interval is reduced, and the overall cashing rate of the line plan running diagram is guaranteed to the maximum extent.

    本发明提供一种CBTC列车区间降级防护方法及装置,该方法包括:在列车发生信号故障而丢失定位的情况下,根据所述列车经过的应答器的轨道偏移量,确定所述列车的当前位置;在所述列车的运行方向上,从所述列车的当前位置开始进行进路搜索,直到搜索到对向道岔位置;其中,所述列车的运行方向在所述列车发生故障之前获得;将所述当前位置与所述对向道岔位置之间的进路作为自主移动授权,并根据自主移动授权的进路计算所述列车的第一防护曲线。本发明实现列车在区间降级后,在车载信号设备防护下安全运行,提高列车运行速度,降低对运营间隔造成的影响,最大限度保障线路计划运行图的整体兑现率。
