The invention provides a method for judging the slipping state of a train, which comprises the following steps of: when a distance measurement error judgment item of a first duration meets a first preset condition, judging that the train enters a pre-slipping state; when the distance measurement error judgment item of the second duration meets a second preset condition, it is judged that the train enters the slipping state; wherein the first duration is any time period in the running process of the train, and the second duration is a time period formed by combining the first duration and a time period after the train enters the pre-slipping state. According to the method, the slip entering time points of the trains with various braking characteristics can be accurately judged, and a slip compensation mechanism is accurately involved, so that the speed measurement and distance measurement errors of a signal system when the subway train slips are reduced.

    本申请提供一种列车打滑状态的判定方法,包括以下步骤:当第一时长的测距误差判定项满足第一预设条件时,判定所述列车进入预打滑状态;当第二时长的测距误差判定项满足第二预设条件时,判定所述列车进入打滑状态;其中,所述第一时长为列车行驶过程中的任一时间段,所述第二时长为第一时长与列车进入预打滑状态后的时间段所合并形成的时间段。该方法可以精确判断各种制动特性的列车的打滑进入时间点,让打滑补偿机制准确地介入,从而减少地铁列车在打滑时信号系统的测速和测距误差。
