  • Patent number: 11938984
    Abstract: 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.

  • Publication number: 20230257011
    Abstract: The present disclosure relates to a system and method for automatic adjustment of a planned train operation chart. The system comprises a train operation data analysis module, a passenger flow data matching module, and an operation chart adjustment module that are connected in sequence. The train operation data analysis module is connected to the operation chart adjustment module; the train operation data analysis module assesses the deviation between an actual operation chart and a planned operation chart on the basis of ATS historical operation data to obtain an operation chart assessment result; the passenger flow data matching module calculates the actual passenger flow distribution on the basis of on-board weighing passenger flow data and AFC passenger flow data, and matches the actual passenger flow distribution with the actual operation chart to obtain a passenger flow matching result; and the operation chart adjustment module performs optimizing adjustment.
