It should be noted that, the data downloading manner of each device in the main control system of the target control terminal 90 and the data downloading manner of each device in the main control system of the other control terminal 91 are described above, and are not described in detail herein.

The data downloading manner of each device of the standby control system of the target control end and the data downloading manner of each device of the standby control system of the other control end are described in the following manner:

an alternative implementation manner is that after determining the target line, the ATP in the main control system of the target control end informs the ATP in the standby control system of the target control end to download the line configuration data of the target line; correspondingly, after receiving the notification sent by the ATP in the main control system of the target control end, the ATP in the standby control system of the target control end downloads the line configuration data of the target line.

After receiving a target line identifier sent by ATP in a main control system of a target control end, informing ATO in a standby control system of the target control end to download line configuration data of a target line; correspondingly, after receiving the notification sent by the ATO in the main control system of the target control end, the ATO in the standby control system of the target control end downloads the line configuration data of the target line.

The IF in the main control system of the target control end informs the IF in the standby control system of the target control end to download the line configuration data of the target line after receiving the target line identifier sent by the ATP in the main control system of the target control end; correspondingly, after receiving the notification sent by the IF in the main control system of the target control end, the IF in the standby control system of the target control end downloads the line configuration data of the target line.

After receiving the target line identifier sent by the ATP in the main control system of the target control end, the ATP in the main control system of the other control end notifies the ATP in the standby control system of the other control end to download the line configuration data of the target line; correspondingly, after receiving the notification sent by the ATP in the main control system of the other control end, the ATP in the standby control system of the other control end downloads the line configuration data of the target line.

The ATO in the main control system of the other control end notifies the ATO in the standby control system of the other control end to download the line configuration data of the target line after receiving the target line identification sent by the ATP in the main control system of the other control end; correspondingly, after receiving the notification sent by the ATO in the main control system of the other control end, the ATO in the standby control system of the other control end downloads the line configuration data of the target line.

IF in the main control system of other control end, after receiving the target line identification sent by ATP in the main control system of other control end, notifying IF in the standby control system of other control end to download the line configuration data of the target line; correspondingly, the IF in the standby control system of the other control end downloads the line configuration data of the target line after receiving the notification sent by the IF in the main control system of the other control end.

After notifying other devices to download configuration data of a target line, the master control device in the target control end of the train in the embodiment of the application judges whether the train meets the line switching condition, and if yes, the master control device in the target control end controls the train to switch the line.

In implementation, a main control device in a target control end judges whether a train meets a line switching condition according to a running position of the train and a preset switching area;

optionally, in the embodiment of the present application, the preset switching area may be a partial area in the overlapping area;

for example, as shown in fig. 10, the route 1 is a route section between the point a and the point B, and the route 2 is a route section between the point C and the point D; the overlapping area of the line 1 and the line 2 is the area between the point C and the point B; the preset switching region may be a region between the point E and the point F shown in fig. 10.

An alternative implementation manner is that the main control equipment in the target control end determines that the line switching condition is met according to the following manner:

if the slave control equipment in the target control end, the master control equipment in the other control ends and the slave control equipment are determined to download the line configuration data of the target line, and the train is determined to be positioned in a preset switching area according to the current running position of the train, the master control equipment determines that the line switching condition is met; or (b)

If it is determined that the slave control device in the target control end, the master control device in the other control ends and the slave control device have devices which do not download the line configuration data of the target line, and according to the current running position of the train, it is determined that the train is currently running to a switching end point of a preset switching area, then the master control device determines that the line switching condition is met.

In the implementation, the master control equipment in the target control end is ATP, and the slave control equipment comprises ATO and IF; the master control equipment in other control terminals is ATP, and the slave control equipment comprises ATO and IF; and determining ATO and IF in the target control end, ATP in other control ends and ATO and IF in other control ends by ATP in the target control end to download line configuration data of the target line, and determining that the train meets line switching conditions after the train runs to a preset switching area.

In addition, in order to ensure normal running of the train, a certain distance exists between a switching end point of a preset switching area and an end point of an overlapping area; when the train runs to the switching end point, whether each device downloads the line configuration data of the completed target line or not, the train needs to execute the line crossing operation;

therefore, IF the ATP in the target control end determines that the ATO and the IF in the target control end, the ATP in the other control ends, and some or all of the ATO and the IF do not download the line configuration data of the completed target line, when determining that the train currently travels to the switching end point of the preset switching area, the ATP in the target control end determines that the train meets the line switching condition.

It should be noted that, when the target control end and the other control ends of the embodiment of the present application include the main control system and the standby control system, the ATP in the target control end needs to determine the ATO and the IF of the main control system in the target control end, the ATP, the ATO and the IF of the standby system in the other control ends, and whether all the devices of the ATP, the ATO and the IF of the standby control system in the other control ends download the line configuration data of the completed target line.

When judging whether each device downloads the line configuration data of the finished target line, the ATP in the target control end judges whether each device downloads the line configuration data of the finished target line according to the overline state of each device.

After the train enters the overlapping area of at least two lines, the overline state of each device in the target control end and other control ends can comprise: an initial state, a hot loading state, and a hot switching state;

in the initial state, each device can receive a data downloading command of the target line data; after receiving the data downloading command, the overline state of each device is switched from the initial state to the hot loading state;

under the hot loading state, each device respectively judges whether the cache contains the line configuration data of the target line, if so, the line configuration data of the target line is loaded into the respective memory, and the line crossing state of the device is switched to the hot switching state; otherwise, if the line configuration data of the target line is not provided, the line configuration data of the target line is downloaded to the cache, the line configuration data of the target line in the cache is loaded into the respective memory, and the line crossing state of the device is switched to the hot switching state.

In the hot switching state, each device in the target control end and other control ends switches the data pointer to the line configuration data of the target line after receiving the switching instruction, and converts the corresponding data.

In each overline state, each device can receive a plurality of data downloading instructions; if the target line identifier contained in the last received data downloading instruction is different from the target line identifier contained in the previously received data downloading instruction, the line data query is performed again.

In the implementation, each device of the target control end and other control ends of the embodiment of the application periodically feeds back the information such as the current overline state, the data version and the like to the ATP in the target control end;

it should be noted that IF the ATO and the IF in the target control end and the ATP, ATO and the IF in the other control ends receive the switching instruction notified by the ATP in the target control end in the initial state or the hot-loaded state, it is determined that the line crossing fails, and the switching instruction may not be executed.

2. And (3) a line switching process.

It should be noted that, in the train switching process, after the master control device and the slave control device in the target control end and the master control device and the slave control device in the other control ends download the line configuration data of the target line, the master control device and the slave control device in the target control end and the master control device and the slave control device in the other control ends switch to the line configuration data of the target line after determining that the line switching condition is satisfied.
