[0002]
[Prior art]
In general, in-vehicle transmission devices that perform data transmission between vehicles are required to be able to continue data transmission between vehicles even when the transmission line is disconnected, and a recovery function in the event of an abnormality is required. . For this reason, a transmission station is provided in each vehicle, and each transmission station is connected by a double loop to ensure reliability. That is, even if the transmission line between the vehicles is disconnected at one place, a detour can be configured to ensure reliability.

For example, the transmission path for transmission from the terminal apparatus 61 to the terminal apparatus 65 is as follows: terminal apparatus 61 → transmission station ST1A → transmission path 12 → transmission station ST2A → transmission path 23 → transmission station ST3A → transmission path 34 → transmission station ST4A. → Transmission path 45 → Transmission station ST5A → Terminal device 65. Alternatively, terminal device 61 → transmission station ST1B → transmission channel 21 → transmission station ST2B → transmission channel 32 → transmission station ST3B → transmission channel 43 → transmission station ST4B → transmission channel 54 → transmission station ST5B → terminal device 65.
[0023]
FIG. 2 is an explanatory diagram of transmission path reconfiguration when the first transmission path is disconnected at several points. Now, a transmission path 21 between the transmission stations ST1B and ST2B, a transmission path 23 between the transmission stations ST2A and ST3A, a transmission path 43 between the transmission stations ST3B and ST4B, and a transmission station ST4A And the transmission line 45 between the transmission station ST5A are disconnected at the same time.

In this case, the transmission path for transmission from the terminal apparatus 61 to the terminal apparatus 65 is as follows: terminal apparatus 61 → transmission apparatus ST1A → transmission path 12 → transmission station ST2A → transmission path 22 → transmission station ST2B → transmission path 32 → transmission station ST3B → transmission path 33 → transmission station ST3A → transmission path 34 → transmission station ST4A → transmission path 44 → transmission station ST4B → transmission path 54 → transmission station ST5B → terminal device 65. Thus, when the first transmission line connecting between the transmission stations ST of the vehicle is disconnected at a plurality of locations, the second transmission line 22 connecting between the transmission stations STA and STB in the vehicle, A detour is constituted by 33 and 44. Thereby, it becomes possible to continue transmission between vehicles.
[0025]
FIG. 3 shows a configuration example of a transmission path when the train shown in FIG. 1 is divided between the vehicle 3 and the vehicle 4. The transmission path in this case is a loop connection similar to the configuration shown in FIG. Therefore, when the divided transmission path is disconnected, the transmission path (line) as described in FIG. 2 is reconfigured.

In this case, the transmission path for transmission from the terminal apparatus 61 to the terminal apparatus 65 is as follows: terminal apparatus 61 → transmission station ST1 → transmission path 12 → transmission station ST2 → transmission path 23 → transmission station ST3 → transmission path 35 → transmission station ST5 → terminal device 65. Thus, when the transmission line connecting between the transmission stations ST of the vehicle is disconnected at a plurality of locations, the transmission path is set in the normal transmission path among the transmission paths connecting the transmission stations ST of the vehicle. Since reconfiguration is performed, it becomes possible to continue transmission between vehicles.
[0040]
FIG. 9 illustrates a configuration example of a transmission path when the train illustrated in FIG. 7 is divided between the vehicle 3 and the vehicle 4. The transmission path in this case is the same as that shown in FIG. 7 except that the number of vehicles is different.
