Field: Transport (Mechanical engineering)
Classification: CPC B | IPC B

Claim 0:
1. A multi-layer coupling relationship-based train operation deviation propagation condition recognition and adjustment method, comprising the following steps:
recognizing an effective train event time sequence, comprising an arrival event and a departure event of a train at each passing station;
uniformly extracting train activity data, comprising a stop activity, a section operation activity, a turn-back activity, and an arrival or departure interval activity;
constructing coupling relationship groups between a train event and a train activity and between train activities;
performing statistics on changes of train operation deviation in each relationship group to determine a respective distribution function and a time-space distribution visualized result;
determining a propagation condition of the train operation deviation in a space-time range for the multiple trains based on the respective distribution function and the time-space distribution visualized result; and
performing a feedback optimization to adjust real-time train operation for the multiple trains based on the propagation condition of the train operation deviation.
