The invention provides a safety tracking method and device with unknown integrity of a freight railway train. The method comprises steps that when integrity of a current vehicle is unknown, vehicle tail safety protection point position information of a front vehicle is received, and driving permission of the front vehicle is calculated; a blocking point is set at the position of a safety protection point at the tail of the front vehicle, the position where the blocking point retracts for a certain safety protection distance is taken as a driving permission end point of the rear vehicle, and anunknown integrity state of the front vehicle is reported to CTC equipment; and when the safety headstock position of the rear vehicle and the tailstock safety protection point position of the front vehicle are located in the same section or adjacent sections and the front vehicle has a communication fault, a front-end suspicious mark is added to the rear vehicle, so the rear vehicle drives according to the driving permission. In this way, according to the operation state reported by the preceding train and the current position information, station yard information is combined, running permission is calculated for subsequent train tracking under the condition that the integrity is unknown, operation efficiency is improved, and potential safety hazards are reduced.
本发明提供了一种货运铁路列车完整性未知时的安全追踪方法及装置。所述方法包括当前车完整性未知时,接收前车的车尾安全防护点位置信息,计算前车的行车许可;在前车的车尾安全防护点位置设置封锁点,以封锁点回撤一段安全防护距离的位置作为后车的行车许可终点,向CTC设备汇报前车完整性未知状态;在后车的安全车头位置与前车的车尾安全防护点位置位于同一个区段或位于相邻区段且前车通信故障时,为后车增加前端可疑标记,使后车根据行车许可行驶。以此方式,能够根据前车汇报的运行状态和当前位置信息,结合站场信息,为完整性未知情况下的后续追踪列车计算行车许可,提高运行效率,降低安全隐患。
