In-tunnel vehicle automatic light changing system based on physiological comfortability

Abstract

The invention discloses an in-tunnel vehicle automatic light changing system based on physiological comfortability. The system includes an illuminance detection unit, an index detection unit, an illuminance compensation device, an index adaptability device and a headlamp controlling device, the illuminance detection unit is connected with a photoelectric illuminance meter, and the input of the illuminance detection unit is connected with the illuminance compensation device; the input of the index detection unit is connected with a speed sensor, a heart-rate sensor, a myoelectricity sensor and an eye-movement device, the output of the index detection unit is connected with the input of the index adaptability device, the output of the index adaptability device is connected with the input of the illuminance compensation device, the illuminance compensation device and a timer are in both-way connection, and the output of the illuminance compensation device is connected with the headlamp controlling device. According to the system, a traditional tunnel lighting mode is changed, wherein in the traditional tunnel lighting mode, fixed lighting facilities are used as illumination compensation sources, and in the in-tunnel vehicle automatic light changing system, dynamic headlamps of mobile vehicles are used as the illumination compensation sources.

Description

technical field

[0001] The invention relates to the technical field of traffic safety, in particular to an automatic dimming system for vehicles in tunnels based on physiological comfort. Background technique

[0002] In recent years, the number of road tunnels has increased day by day. Road tunnels are special road sections, and the environment inside and outside the tunnel is very different. It is necessary to install electro-optical lighting in the tunnel to eliminate the driver's "dark adaptation" and "bright adaptation" visual problems and ensure tunnel driving. Safety. However, how to create a good driving visual environment in expressway tunnels while achieving energy saving and emission reduction is a problem worthy of research and discussion. At present, most road tunnel lighting control systems are simple, and the comfort of lighting sources is not high. The brightness of the lighting in the tunnel is not adjusted in real time according to the brightness of the en...
