Abstract

The invention discloses a control method, apparatus, and system of a rail vehicle lighting system and a rail vehicle. The method comprises the following steps: determining the total current of a cool color temperature LED and a warm color temperature LED according to target brightness, wherein the target brightness is determined according to the illuminance of an environment where the rail vehicle is located; determining the light ratio of the cool color temperature LED and the warm color temperature LED according to target color temperature, wherein the target color temperature is determined according to current time; and controlling the operation of the cool color temperature LED and the warm color LED according to the total current and the light ratio. The control method, apparatus, and system solve the technical problem that the light source of the rail vehicle has large energy consumption and low comfortableness in the prior art.

Description

technical field [0001] The invention relates to the field of rail vehicle control, in particular to a control method, device, system and rail vehicle lighting system of a rail vehicle. Background technique [0002] With the progress of society, saving energy and protecting the environment has become the trend of the world. In the field of lighting, lighting control plays an important role in this. The traditional lighting control is to add a switch at the lighting circuit, and the switch controls the lighting. Further, the dimming function is added, and the brightness of the lamp is controlled by the thyristor or PWM technology. [0003] Although almost all newly designed models use LED light sources, the lighting of the passenger compartments of train vehicles still consumes a large part of energy; for the mobile environment of train compartments, the main lighting is always turned on even when driving on sunny ground , unless controlled by a driver or flight attendant. ...
