IN-CAB DISPLAY SYSTEM AND DISPLAY CONTROL METHOD FOR IN-CAB DISPLAY DEVICE

摘要

The purpose of the present invention is to obtain an in-cab display system equipped with an in-cab display device capable of automatically adjusting the display brightness of a display device without using an illuminance sensor and to obtain a display method for the in-cab display system. On the basis of the position information of a train sent from a train information control system (1), the in-cab display device (10) determines whether the train is running in a tunnel or not. When it is determined that the train is running in the tunnel, a brightness preset for the inside of a tunnel is set as the brightness of a display screen. When it is determined that the train is running outside the tunnel, brightness information preset for the outside of a tunnel is set as the brightness of the display screen.
