Abstract

The invention discloses a tunnel illumination control method based on human eye visual characteristics. The method comprises the following steps that: external brightness is detected by an ambient light detection module, invisible light in ambient light is filtered by a y optical filter in the ambient light detection module to reduce interference of invisible light intensity fluctuation on a measurement result; the collected ambient light illuminance signal of the visible light waveband is converted into an analog voltage signal by an AD conversion module; and a main controller adjusts the illumination brightness of lamps in the tunnel to be kept in a range comfortable for human eyes according to a result obtained by calculation after carrying out weighting processing on the converted ambient light illuminance analog voltage signal. By improving the ambient light sensing precision and the lamp brightness control method, tunnel illumination better conforms to the visual characteristicsof human eyes, the visual adaptation load of a driver entering and exiting a tunnel is reduced, the driving safety is improved, and the energy saving performance of a tunnel illumination system is improved.

Description

technical field [0001] The invention belongs to the technical field of tunnel lighting, and in particular relates to a tunnel lighting control method based on human visual characteristics. Background technique [0002] Traditional tunnel lighting cannot adapt to the change of external light intensity. Often, the arrangement of lamps and lanterns according to the maximum brightness during the day will lead to excessive lighting at night, resulting in unsafe driving; while the new tunnel lighting control method is often sensitive to ambient light. The perception is not accurate enough. When the human eye is in the dark vision area with poor adaptability to light intensity changes at night, inaccurate lighting control will increase the photosensitive load of the human eye and cause driving safety hazards; on the other hand, during the photosensitive period Invisible light is not filtered out by a filter, which makes the detection of visible light more prone to errors and uncont...
