  • Patent number: 12162526
    Abstract: A train operation control method includes acquiring a battery state of an arriving train, and determining a target dwell time of the arriving train according to the battery state of the arriving train, actual operation data of the arriving train, and planned operation data of the arriving train, so that the arriving train stops for charging according to the target dwell time. The actual operation data of the arriving train includes an actual arrival time of the arriving train, and the planned operation data of the arriving train includes a planned arrival time, a planned dwell time, a minimum dwell time, and a maximum dwell time of the arriving train.

  • Patent number: 11820410
    Abstract: A train dispatching method includes acquiring a battery state of a power battery of a first target train, and determining that the first target train is a train about to return to the garage if the battery state is a power shortage state. The method further includes controlling the first target train to travel back to the parking garage for charging in response to receiving a passenger-drop-off completion instruction, selecting a train in a power sufficient state as a second target train from assignable trains in the parking garage if the battery state is the power shortage state, determining target dispatching plan information of the second target train according to original dispatching plan information of the first target train, and dispatching the second target train according to the target dispatching plan information.
