Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

Configuring the routing path of the switch in the train network system, so that the train data is transmitted through the data landing channel of the corresponding mode when the train is in different lines.
[0021] The above-mentioned configuration of the routing path of the switch in the train network system specifically comprises: VLAN configuration, WAN address configuration, NAT address conversion configuration and static route configuration of the switch in the train network system. According to the line boundary information, the current line where the train is located is determined, wherein the line boundary information is the BLOCK point table sent by the signal system and the line division point determined according to the BLOCK point table.
[0022] The above-mentioned determination of the current line where the train is located according to the line boundary information specifically comprises: When both ends of the train are within the BLOCK range of the first line, it is determined that the train is currently located in the first line. When both ends of the train are in the BLOCK range of the second line, it is determined that the train is currently located in the second line; When the train head in the uplink direction crosses the first line end BLOCK and enters the second line start BLOCK, it is determined that the train switches from the first line to the second line; When the train head in the downlink direction crosses the second line end BLOCK and enters the first line start BLOCK, it is determined that the train switches from the second line to the first line.
[0023] According to the current line where the train is located, the train data is transmitted to the ground server through the corresponding mode data landing channel.
[0024] When the train switches lines, the routing path is switched synchronously, and the transmission of train data is switched to the current corresponding mode data landing channel, realizing seamless connection of different mode data landing channels; Among them, when the train switches lines, the routing path is switched synchronously, specifically including: When the train switches lines, the routing path is switched according to the BLOCK point table sent by the signal system and the IP address in the ground server heartbeat information.
[0025] For example, the train control and management system divides the positions of line a and line b according to the BLOCK point table provided by the signal system, as follows: According to the BLOCK point table provided by the signal system, when both ends of the train belong to the BLOCK range of line b, it is determined that the train is currently located in line b; when both ends of the train belong to the BLOCK range of line a, it is determined that the train is currently located in line a.
[0026] According to the BLOCK point table and the running diagram provided by the signal system, when at the line switching point of line b and line a, the line switching is determined according to the active end and the train direction, as follows: Upward direction: when the train head crosses B856 and enters B680, it is determined to enter line a from line b; when the train head crosses B680 and enters B856, it is determined to enter line b from line a; Downlink direction: when the train head crosses B684 and enters B1018, it is determined to enter line b from line a; when the train head crosses B1018 and enters B684, it is determined to enter line a from line b; When the BLOCK signal sent by the signal system is not in the valid range, the fault state is maintained.
