The invention provides a train integrity checking method and system based on integrated navigation. The method comprises the steps that first train motion state data corresponding to the train head of a train and second train motion state data corresponding to the train tail of the train are obtained respectively; calculating a difference value between the first train motion state data and the second train motion state data, and when the difference value is greater than a set threshold value and is kept for a period of time, judging that the integrity of the train is lost; wherein when the train cannot receive the satellite signal or the failure time of the received satellite signal is greater than or equal to a time critical value, the first train motion state data is first acceleration information corresponding to the train head, and the second train motion state data is second acceleration information corresponding to the train tail. According to the invention, the accuracy, safety and reliability of train integrity inspection are improved, and the integrity of the train can be effectively judged during emergency braking.

    本发明提供了一种基于组合导航的列车完整性检查方法和系统,所述方法包括:分别获取列车的列首对应的第一列车运动状态数据和列尾对应的第二列车运动状态数据;计算所述第一列车运动状态数据和第二列车运动状态数据的差值,当差值大于设定的阈值并保持一段时间后,则判定列车的完整性丢失;其中,当列车接收不到卫星信号或接收到的卫星信号的失效时间大于等于时间临界值时,所述第一列车运动状态数据为列首对应的第一加速度信息,所述第二列车运动状态数据为列尾对应的第二加速度信息。本发明提高了列车完整性检查的准确性、安全性、可靠性,且在紧急制动时也可有效判断列车的完整性。
