The invention relates to an operation diagram-based method for automatically changing a route to turn back in case of interruption. The method obtains an alternative turn-back point according to the position of a fault point and the information of a line turn-back station, calculates a corresponding turn-back plan of the alternative turn-back point according to an operation diagram of the current day, and finally automatically changes an online train route according to the new turn-back plan, so as to realize automatic turn-back of a train after route adjustment in case of interruption. Compared with the prior art, the method has the advantage of being able to keep the compatibility with an existing operation diagram while quickly changing a route in case of partial line interruption, so as to facilitate quick recovery of planned operation after a fault is removed.

Operation diagram-based method for automatically changing route to turn back in case of interruption

The present invention relates to a full-day in each train operation diagram generation method based on a time division scheme and an activity-event relationship, the method including: S1: configuring operation scheme basic parameters; S2: constructing a quantitative relationship between a travel time and a driving interval for different routing ratios and calculating, within a given turn-back time range, an actual turn-back time of each turn-back station that can achieve a routing ratio requirement; S3: generating an arrival event time and a departure event time of a train in each time period at a station platform in accordance with routing division, direction division, and proportion division, correcting a start time and a stop time of each routing in accordance with time period division, and performing transition between the time periods; and S4: connecting a train section operation activity and a stop activity according to the full-time train arrival and departure event times obtained by executing step S3 for a plurality of times, matching an underbody turn-back activity with ex-warehousing and warehousing activities, and correcting arrival and departure times related to a track occupation conflict, thus obtaining a full-day train operation diagram. Compared with the prior art, the present invention has the advantages of a standardized routing ratio, automatic high-low peak connection transition, and the like.

The present invention relates to a multi-layer coupling relationship-based train operation deviation propagation condition recognition method, where the method includes the following steps: (1) recognizing an effective train event time sequence, including an arrival event and a departure event of a train at each passing station; (2) uniformly extracting train activity data, including a stop activity, a section operation activity, a turn-back activity, and an arrival or departure interval activity; (3) constructing coupling relationship groups between a train event and a train activity and between train activities; and (4) performing statistics on changes of train operation deviation in each relationship group, and outputting a respective distribution function and a time-space distribution visualized result. Compared with the prior art, the present invention has the advantages of being practical, automatic recognition, feedback optimization, and the like.
