The invention relates to a train positioning method and system based on a cross induction loop line. The method comprises the following steps that a vehicle-mounted ATP verifies the position of a loop line boundary by detecting the position when an area identification number is received; the vehicle-mounted ATP judges the running direction of the current line according to the loop line position number sent by the ground loop line; the vehicle-mounted ATP continuously receives the loop line position number to complete positioning initialization of the train; after the train is positioned, the vehicle-mounted ATP receives a position signal of a cross point or an effective loop boundary in an expected window and corrects the current position of the train; the system comprises a vehicle-mounted ATP and a ground loop line. The train positioning method has the effect of positioning the train through the train-mounted ATP under the condition that a line electronic map does not need to be stored.
本发明涉及一种基于交叉感应环线的列车定位方法及系统,所述方法包括以下步骤:车载ATP通过检测收到区域标识号时的位置来验证环线边界的位置;车载ATP通过地面环线发送的环线位置号判断当前线路的运行方向;车载ATP持续接收环线位置号完成列车的定位初始化;列车定位之后,车载ATP收到预期窗口内的交叉点或者有效环线边界的位置信号,对列车当前位置,进行校正;所述系统包括车载ATP和地面环线。本发明具有在无需存储线路电子地图的情况下通过车载ATP进行列车定位的效果。
