In one example, as shown in fig. 2, the control signal output device 12, the switch signal input device 13, and the semaphore signal input device 14 are each connected to the interface device 17 to send control signals to the interface device 17 and/or to receive electrical signals from the interface device 17. Alternatively, the interface device 17 may be a relay combination corresponding to a signal machine and a switch device. Optionally, the interface device 17 may further comprise a relay arrangement corresponding to the rail device. The interface device 17 is typically located in a facility room of the docking station.

In one example, the output module 112 is connected with the control signal output device 12 through a plurality of ports; the input module 113 is connected with the turnout signal input device 13 and the signal input device 14 through a plurality of ports. In the mode of parallel connection of multiple ports, the data transmission speed between the control device 11 and other devices (the control signal output device 12, the switch signal input device 13, and the traffic signal input device 14) can be increased.
