In operation S1, a closing symbol is drawn in case of emergency during train operation, and a closed section for adjusting a train operation diagram and adjustment conditions for the operation diagram are determined by the closing symbol.
Specifically, in case of emergency such as failure of section equipment and failure of station equipment during train operation, the closing symbol of construction needs to be drawn first to determine the closed section such as a closed district or a closed station, and the adjustment conditions for the train operation diagram are determined. The closing symbol includes information of the closed station, a closing time period, and a closing direction. The closed station includes first and last stations in the closed section; the closing time period includes start time and end time of closing; and the closing direction is an up, down, or up-down direction in which train operation is not allowed. The train operation diagram is an operation plan diagram of a train operating in a railway section and at a time point of arriving at, departing from or passing through a station. In this embodiment, the train requiring emergency dispatching may be selected by the determined closed section or adjustment conditions for the train operation diagram.

In this embodiment, it is possible to obtain an operation time point of each train, then analyze all trains requiring emergency dispatching and whose operation time points are affected based on the obtained train adjustment time range, and form the train set to be adjusted.
In operation S3, a train with failure in the closed section is obtained, and resource occupancy is registered based on the closing symbol and the train with failure in the closed section to generate a resource occupancy list.
In this embodiment, the resource occupancy may be registered based on the closing symbol on the operation diagram within the adjustment time range and the train with failure in the closed section, where the resource occupancy includes resource occupancy of a station entrance, resource occupancy of a station track, resource occupancy of a station exit, and resource occupancy of a departure section. In this embodiment, the resource occupancy of each station in the closed section may be obtained by the resource occupancy list.
In operation S4, station track adjustment and calculation, arrival and departure time adjustment and calculation, and section operation time adjustment and calculation are performed on each train in the train set to be adjusted based on the resource occupancy in the resource occupancy list, and a corresponding adjustment result is calculated.

The adjustment starting position or the adjustment finishing position includes the station entrance, the station track, the station exit, and the departure section. The station is a current adjusted station.
Specifically, after the train set to be adjusted is obtained based on the adjustment time range determined by a dispatcher, the adjustment starting station, the adjustment finishing station, the adjustment starting position, and the adjustment finishing position for each train may be calculated based on a relationship between the operation time point of each train in the train set to be adjusted and the set adjustment time range.

Arrival and departure time includes arrival time and departure time of the train at the current adjusted station, and the operation of performing arrival time adjustment and calculation on the train based on the resource occupancy of the station entrance includes:
When the adjusted arrival time Tal does not meet the preset arrival time requirement, it is possible to return to a previous adjusted station STAn-1 and modify departure time Td of the train at the previous adjusted station STAn-1 to Td1 based on access time Taccess of the current adjusted station STAn calculated and recommended by a system, and repeat the operation of performing arrival time adjustment and calculation on the train based on the resource occupancy of the station entrance at the previous adjusted station STAn-1.
In one embodiment of the present disclosure, the operation of performing station track adjustment and calculation on the train based on the resource occupancy of the station track includes: obtaining a planned station track and an arrival and departure mode of the train at the current adjusted station STAn, and checking the resource occupancy of the station track of the current adjusted station STAn based on the planned station track and the arrival and departure mode; and calculating whether the station track needs to be adjusted based on the checked resource occupancy of the station track, adjusting the station track when the station track needs to be adjusted, and proceeding to operation of performing departure time adjustment and calculation on the train based on the resource occupancy of the station exit when a station track adjustment result meets a preset station track adjustment requirement.
When the station track adjustment result does not meet the preset station track adjustment requirement, it is possible to return to the previous adjusted station STAn-1 and modify the departure time Td of the train at the previous adjusted station STAn-1 to Td1 based on the access time Taccess of the current adjusted station STAn calculated and recommended by the system, and repeat the operation of performing arrival time adjustment and calculation on the train based on the resource occupancy of the station entrance at the previous adjusted station STAn-1.
In one embodiment of the present disclosure, the operation of performing departure time adjustment and calculation on the train based on the resource occupancy of the station exit includes: obtaining the departure time of the train at the current adjusted station STAn, and checking the resource occupancy of the exit of the current adjusted station STAn based on the departure time; and calculating adjusted departure time of the current adjusted station STAn based on the checked resource occupancy of the exit, and proceeding to operation of performing section operation time adjustment and calculation on the train based on the resource occupancy of the departure section when the adjusted departure time meets a preset departure time requirement.
In one embodiment of the present disclosure, the operation of performing section operation time adjustment and calculation on the train based on the resource occupancy of the departure section includes:
obtaining the departure time Td and planned section operation time ΔTrun of the train at the current adjusted station STAn, checking the resource occupancy of the departure section of the current adjusted station STAn based on the departure time Td and the section operation time ΔTrun, and performing section operation time adjustment and calculation on the train based on the checked resource occupancy of the departure section.
Specifically, when there is the closing symbol in the departure section and a departure route of the train has been triggered, handled, or occupied, the system may stop the train in the departure section until end time Tobt of the closing symbol and adjust arrival time of the train at the next adjusted station STAn+1 based on a stop duration, then the next adjusted station STAn+1 is entered, and the operation of performing arrival time adjustment and calculation on the train based on the resource occupancy of the station entrance is repeated at the next adjusted station STAn+1. When there is the closing symbol in the departure section and the departure route of the train has not been handled, the train may be stopped at the station based on the end time Tobt of the closing symbol, then the departure time Td of the current adjusted station STAn is adjusted to Td1, and then the operation of performing arrival time adjustment and calculation on the train based on the resource occupancy of the station entrance is repeated for the current adjusted station STAn.
When there is no closing symbol in the departure section, the adjustment may be performed based on other resource occupancies such as the resource occupancy of the station entrance. In this embodiment, when the resource occupancy of the departure section does not meet a departure requirement, the departure time Td of the current adjusted station STAn needs to be adjusted to Td1, and then the operation of performing arrival time adjustment and calculation on the train based on the resource occupancy of the station entrance is repeated for the current adjusted station STAn. When the departure requirement is met, the arrival time of the train at the next adjusted station STAn+1 is modified based on the corresponding adjustment result, then the next adjusted station STAn+1 is entered, and the operation of performing arrival time adjustment and calculation on the train based on the resource occupancy of the station entrance is repeated for the next adjusted station STAn+1.
After the single train adjustment and calculation module traverses the station track adjustment and calculation, the arrival and departure time adjustment and calculation, and the section operation time adjustment and calculation from the adjustment starting position of the adjustment starting station to the adjustment finishing position of the adjustment finishing station, single train adjustment is finished.
In operation S5, the adjustment result of each train is applied to a corresponding planned line in the operation diagram, so as to complete automatic adjustment of the operation diagram.
Specifically, a single train adjustment result may be allocated to the operation line. For example, the adjustment of the arrival and departure time, the station track, and the departure section may be performed on arrival and departure points of the adjusted station requiring train adjustment in an operation line adjustment module. In this embodiment, after the adjustment result of each train is applied to the corresponding planned line in the operation diagram, an operation result after application may be further updated to the resource occupancy list, so as to update the resource occupancy list in real time.
