The brake sensor is provided in proximity to the brake device 193 of the driving devices 190 to detect a state thereof.

The direction sensor detects the driving direction (forward or backward) and the stop state of the vehicle.

The control air pressure sensor senses that the air pressure, that is, the pressure of the air (hereinafter referred to as control air) for controlling the driving device of the locomotive is kept constant. This is because all the driving devices of the locomotive are controlled by the pressure of the control air, and this is to detect the vehicle since the vehicle cannot be driven unless the control air maintains a constant input.

The input processing unit 140 is provided with a sensor connection terminal 141 for electrically connecting with each of the plurality of sensors 130, and the sensing signal detected through the plurality of sensors 130 is connected to the sensor connection terminal 141.
