Embodiment 1

[0031] Embodiment 1 of the present invention provides an intelligent dimming method for tunnel lighting, such as figure 1 As shown, the tunnel lighting intelligent dimming method mainly includes the following steps:

[0032]Step S101: Obtain brightness information outside the tunnel, weather information, color temperature information, and traffic volume parameters of each section inside the tunnel. The brightness information outside the tunnel is mainly used in two aspects. One is to calculate the target brightness of the tunnel entrance section in the subsequent steps; the other is to determine whether the current time is day or night. is different. Meteorological information mainly refers to normal weather or severe weather, wherein normal weather includes sunny and cloudy days, and severe weather includes fog, rain and snow. Since fog, rain, snow and other unfavorable weather conditions have similar effects on visibility, in order to simplify the calculation, the above un...

Embodiment 2

[0135] Embodiment 2 of the present invention provides an intelligent dimming method for tunnel lighting, including all the steps in Embodiment 1. To avoid repetition, details are not repeated here. The intelligent dimming method for tunnel lighting in Embodiment 2 of the present invention provides a specific dimming control method for the transition section of the tunnel, such as image 3 shown, including the following steps:

[0136] Step S201: Determine the target color temperature of the tunnel transition section according to the target color temperature of the tunnel entrance section. In a specific embodiment, the color temperature of the tunnel transition section may be the same as the color temperature of the tunnel entrance section.

[0137] Step S202: Determine the target brightness of the tunnel transition section according to the target brightness of the tunnel entrance section. In a specific implementation manner, formulas (3)-(5) can be used to calculate the targ...

Embodiment 3

[0173] Embodiment 3 of the present invention provides a non-transitory computer-readable storage medium, the computer-executable instruction is stored in the computer-executable instruction, and the computer-executable instruction can execute the tunnel lighting intelligent dimming method in any method embodiment above. Wherein, the storage medium can be a magnetic disk, an optical disk, a read-only memory (Read-OnlyMemory, ROM), a random access memory (Random AccessMemory, RAM), a flash memory (FlashMemory), a hard disk (HardDiskDrive, abbreviation: HDD) or solid-state hard disk (Solid-State Drive, SSD), etc.; the storage medium may also include a combination of the above-mentioned types of memory.

Abstract

The invention provides a tunnel lighting intelligent dimming method which includes the steps: acquiring brightness information, color temperature information and meteorological information outside a tunnel and traffic volume parameters inside the tunnel; determining brightness reduction coefficient of a tunnel entrance according to the traffic volume parameters, the meteorological information andthe color temperature information entering the tunnel; calculating the object brightness of the tunnel entrance according to the brightness information acquired outside the tunnel and the brightness reduction coefficient of the entrance; determining the object color temperature of the tunnel entrance according to the meteorological information and the color temperature information; adjusting the brightness and the color temperature of the tunnel entrance according to the object brightness and the object color temperature of the tunnel entrance. The tunnel lighting intelligent dimming method changes the shortcoming that time-phased and seasonal constant brightness is simply adopted without taking color temperature and weather effect into consideration in the prior art, the brightness information, the meteorological information and the color temperature information outside the tunnel are comprehensively considered, the color temperature and driving visual demands of a driver are successfully introduced into a tunnel dimming strategy, adaptability and the requirement of tunnel dimming for human eye vision are effectively improved, and tunnel driving safety can be improved.

Description

technical field [0001] The invention relates to the technical field of tunnel lighting, in particular to an intelligent dimming method for tunnel lighting. Background technique [0002] The rapid growth of China's economy has enabled the vigorous development of road traffic construction. Highway tunnels are widely used in highway traffic construction due to their advantages of overcoming height difference, reducing slope, shortening mileage, saving land, and protecting the environment. The total number of highway tunnels constructed and the number of mileage opened to traffic in my country are increasing year by year, especially in the past five years, the growth rate has been particularly fast. By the end of 2016, there were 15,181 highway tunnels nationwide, an increase of 1,175 over the end of the previous year. The mileage opened to traffic reached 14.0397 million meters, an increase of 1.3558 million meters over the end of the previous year. Among them, there are 815...
