According to the alternative embodiment, the checking information which is uploaded by the driving locomotive at regular time in the driving process is obtained, and the corresponding relation table between the driving locomotive identification and the current area of the driving locomotive and the network covered by the area is determined according to the checking information. According to the scheme, the transmission times between the running locomotive and the interface equipment can be reduced by checking the corresponding relation of the information, so that the occupation of bandwidth resources is reduced.
S230, searching a current area of the locomotive to be scheduled in a corresponding relation table according to the locomotive identification of the locomotive to be scheduled, and taking the current area as a target area.

The internet protocol (Internet Protocol, IP) address of the locomotive to be scheduled may be stored in a target database corresponding to the target network, and the storage modes of the IP addresses corresponding to different target networks may be different. For example, if the target network is GSM-R, the IP address of the locomotive to be scheduled may be pre-stored in a database corresponding to the GSM-R network. In addition, the IP address is not changed in the running process of the locomotive to be scheduled. The interface device can search the IP address of the locomotive to be scheduled 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 scheduled may be dynamically stored in a database corresponding to the 5G-R network. Specifically, if the network covered by the target area to which the locomotive to be scheduled belongs is a 5G-R network, the IP address of the locomotive to be scheduled 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.

The different target networks respectively correspond to the DNS servers of the different target networks, and the interface equipment can be respectively connected with the DNS servers corresponding to the different target networks and used for inquiring the IP addresses corresponding to the running locomotives in the different target networks.

It should be noted that, the DNS servers corresponding to different target networks have different structures, for example, DNS servers corresponding to the 5G-R network include a DNS root server and a DNS office server.
In an alternative 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 scheduled from the target DNS, wherein the searching comprises the following steps: searching an IP address of a locomotive to be scheduled from a target office DNS; if the searching fails, searching the IP address of the locomotive to be scheduled from the target root DNS.
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 primary 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 resolved according to a locomotive identification of the locomotive to be scheduled exists from 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 scheduled; if the searching fails, searching whether the IP address of the locomotive to be scheduled exists or not from the DNS root server. If the searching in the DNS root server is successful, the IP address of the locomotive to be scheduled is determined, if the searching in the DNS root server is failed, the searching failure result can be reported to related technicians, and the related technicians can search the IP address manually.
S340, sending scheduling command information to the locomotive to be scheduled according to the IP address of the locomotive to be scheduled.
The interface device sends the scheduling command information to the locomotive to be scheduled through the target network to which the IP address belongs according to the IP address of the locomotive to be scheduled determined in S330.
According to the scheme of the embodiment, the IP address of the locomotive to be scheduled is determined according to the target network; and sending scheduling command information to the locomotive to be scheduled according to the IP address of the locomotive to be scheduled.
