- the switch 31 stops outputting the control command A1 of the ATO1 when receiving the control command B1 from the master controller 2 while outputting the control command A1 of the non-supporting ATO1.
- the control command B1 of the master computer 2 is output.
- the switch 31 outputs the remaining portion of the ATO1 control command A1 that has not been output after the output of the control command B1 of the master controller 2.
- the switch 31 receives the control command A2 from the non-supporting state ATO1 and receives the control command B2 from the master controller 2 during the output of the control command A1 and the control command B1.
- the switch 31 even when the switch 31 receives the control command B2 of the master controller 2 while outputting the remaining unoutputted portion of the control command A1 of the ATO1, for example, when the division number of the control command is set to 2, Alternatively, when the non-output portion of the control command A1 of the ATO1 is equal to or less than the minimum output unit when the control command B2 of the master controller 2 is received, the output of the remaining portion of the control command A1 of the ATO1 that is not output is continued. Next, the switch 31 outputs the control command B2 of the master controller 2, and outputs the control command A2 of the ATO1 after outputting the control command B2 of the master controller 2.

- the command B1, the control command A2, the control command B2, the control command A3, and the control command B3 are output in this order.
- the hub 5 When the hub 5 receives the divided control command from the hub 3, the hub 5 restores the divided control command to one control command and outputs it. At this time, the hub 5 outputs the control command that is not divided with priority over the divided control command. As shown in FIG. 1, the hub 5 includes a part of the control command A1, a control command B1, a remaining part of the control command A1, a control command B2, a part of the control command A2, a control command B3, the remaining part of the control command A2, When the signals are received in the order of the command A3, they are outputted to the recording server 6 and the brake 7 in the order of the control command B1, the control command A1, the control command B2, the control command B3, the control command A2, and the control command A3.

- the hub 5 determines the priority of the invalid control command. Can be accelerated by one output order of the control command B1, one output order of the control command B2, and two output orders of the control command B3. That is, in the transmission system 10, when the operation state of the ATO1 is in the non-supporting state, the priority of the invalid control command is changed to low priority so that control commands transmitted from other control devices other than the ATO1 are given priority. Transmission is possible, and real-time performance can be improved.
