It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Example one
Fig. 1A is a schematic flow chart of a method for sending a scheduling command message according to an embodiment of the present invention, which is applicable to a situation where a CTC system sends a scheduling command message to a terminal of a traveling locomotive when at least one wireless railway communication network exists in a traveling area of the locomotive, where the method may be implemented by a scheduling command message sending device, which may be implemented in software and/or hardware, and the scheduling command message sending device may be configured in the scheduling system shown in fig. 1B.

Wherein the target area may be a current belonging area of the locomotive to be dispatched. The target networks correspondingly covered by different target areas may be the same or different, for example, the target network may be a GSM-R network or a 5G-R network.
The interface device can determine a target network correspondingly covered by a target area to which the locomotive to be dispatched belongs according to the locomotive identification of the locomotive to be dispatched in the acquired dispatching command information. For example, the interface device stores a correspondence between a locomotive identifier of a locomotive to be scheduled, a target area to which the locomotive to be scheduled belongs currently, and a target network correspondingly covered by the target area, where the correspondence may be stored in a database of the interface device, and the correspondence may be obtained from check information periodically sent by the locomotive to be scheduled to the CTC system.

For example, the running locomotive may upload the locomotive identifier of the running locomotive, the area identifier of the current area to which the running locomotive belongs, and the corresponding relationship of the network covered by the area regularly during the running process. The interface equipment acquires the corresponding relation uploaded by the running locomotive at regular time, generates a corresponding relation table and stores the corresponding relation table in a database. The timing time may be set in advance by a person skilled in the art, and may be uploaded every 15 seconds, for example. For example, the expression form of the correspondence stored in the correspondence table may be 10140001-a1-GSM-R, where 10140001 denotes the locomotive identification of the running locomotive itself; a1 represents an area Identifier of an area to which the area belongs, where the area Identifier may be a Global Cell identity (CGI) or a New radio Cell Global identity (NCGI); GSM-R indicates the network covered by the area.

Specifically, the corresponding relationship exceeding the preset cycle number or within the preset cycle time may be deleted or covered in the corresponding relationship table.
For example, if the corresponding relationship within the preset cycle number is reserved in the corresponding relationship table, and the preset cycle number cycle is 500, the corresponding relationship between the locomotive identifier of the running locomotive other than 500, the current area to which the locomotive belongs, and the network covered by the area may be covered or deleted in the corresponding relationship table, and only the corresponding relationship of approximately 500 times is reserved; if the corresponding relation in the preset time period is reserved in the corresponding relation table, and the preset time period is 2 hours, the corresponding relation among the locomotive identification of the locomotive running beyond 2 hours, the current affiliated area of the locomotive and the network covered by the area can be covered or deleted in the corresponding relation table, and only the corresponding relation of nearly 2 hours is reserved.

The checking information includes a locomotive identifier of the running locomotive, a current area of the running locomotive and a network covered by the area, and may further include at least one of a line code, a CGI, an NCG, and the like, which may be specifically set in advance by a related technician.
For example, the interface device obtains the check information periodically uploaded by the driving locomotive during driving, wherein the check information may be periodically uploaded to the CTC system by the driving locomotive through the interface device. After the interface equipment detects the checking information uploaded by the running locomotive at regular time, according to the checking information, a corresponding relation table between the running locomotive identification and the current affiliated area of the running locomotive and the network covered by the area is determined, the corresponding relation table is stored in a database of the interface equipment, and meanwhile, the checking information is sent to a CTC system.
In the optional embodiment, the check information uploaded by the running locomotive at regular time in the running process is acquired, and the corresponding relation table between the running locomotive identifier and the current region of the running locomotive and the network covered by the region is determined according to the check information. According to the scheme, the transmission times between the running locomotive and the interface equipment can be reduced by checking the information corresponding relation, so that the occupation of bandwidth resources is reduced.
And S230, searching the current region of the locomotive to be dispatched in the corresponding relation table according to the locomotive identification of the locomotive to be dispatched, and taking the current region as a target region.

Illustratively, in the correspondence table stored in the interface device database, a correspondence between a locomotive identifier of a locomotive to be scheduled, a current area of the locomotive to be scheduled, and a network covered by the area is stored in a preset time period or a preset time period, and is continuously updated according to a set timing time. Specifically, when the interface device obtains the locomotive identifier of the locomotive to be scheduled, the latest updated corresponding relation stored in the corresponding relation table in a preset time period or a time period is searched, and the current area of the locomotive to be scheduled in the latest updated corresponding relation is used as the target area.
And S240, taking the network covered by the target area as a target network.

And in the running process of the locomotive to be dispatched, the IP address does not change. The interface device can search the IP address of the locomotive to be dispatched in the corresponding database according to the GSM-R network.
For example, if the target network is a 5G-R network, the IP address of the locomotive to be dispatched may be dynamically stored in a database corresponding to the 5G-R network. Specifically, if the network covered by the current target area to which the locomotive to be dispatched belongs is a 5G-R network, the IP address of the locomotive to be dispatched is dynamically updated in the coverage area of the 5G-R network, and the updated IP address is stored in a database corresponding to the 5G-R network.

It should be noted that the DNS servers corresponding to different target networks have different structures, for example, the DNS servers corresponding to the 5G-R network include a DNS root server and a DNS office server.
In an optional embodiment, if the target network is a 5G-R network, the target DNS includes a target office DNS and a target root DNS; searching the IP address of the locomotive to be dispatched from the target DNS, comprising the following steps: searching an IP address of a locomotive to be dispatched from a target office DNS; and if the search fails, searching the IP address of the locomotive to be dispatched from the target root DNS.
And if the target network is a 5G-R network, the target DNS comprises a target office DNS and a target root DNS. The target office DNS can be a DNS office server corresponding to the 5G-R network, and the DNS office server can be a secondary DNS server corresponding to the 5G-R network; the target root DNS may be a DNS root server corresponding to the 5G-R network, and the DNS root server may be a DNS server corresponding to the 5G-R network.
If the target network is a 5G-R network, firstly searching whether an IP address corresponding to a domain name analyzed according to the locomotive identifier of the locomotive to be dispatched exists in a DNS office server corresponding to the 5G-R network, and if the searching is successful, determining the IP address of the locomotive to be dispatched; if the search fails, whether the IP address of the locomotive to be dispatched exists is searched from the DNS root server. If the search in the DNS root server is successful, the IP address of the locomotive to be dispatched is determined, if the search in the DNS root server is failed, the search failure result can be reported to related technical personnel, and the related technical personnel can manually search the IP address.
And S340, sending dispatching command information to the locomotive to be dispatched according to the IP address of the locomotive to be dispatched.
The interface device sends the dispatching command information to the locomotive to be dispatched through the target network to which the IP address belongs according to the IP address of the locomotive to be dispatched, which is determined by S330.
According to the scheme of the embodiment, the IP address of the locomotive to be dispatched is determined according to the target network; and sending dispatching command information to the locomotive to be dispatched according to the IP address of the locomotive to be dispatched. According to the scheme, the IP addresses of the locomotives to be dispatched under different target networks are determined, so that the IP addresses of the locomotives to be dispatched are accurately positioned, the situations that dispatching command information fails due to the fact that the IP addresses are mistakenly sent are avoided, the delivery rate of the dispatching command information is improved, and accurate control over running locomotives is facilitated.
