δ is the change rate of intensity of illumination in the unit time inside and outside tunnel；
N is the tunnel lamp group sum of tunnel exit or entrance gradual change apart from interior setting；
N is n-th of the tunnel lamp group of tunnel exit or entrance gradual change apart from interior setting；
E0The intensity of illumination peak monitored for tunnel exit or entrance external environment；
KN|1Intensity of illumination minimum for tunnel exit or entrance gradual change apart from interior monitoring；
K is PWMnCorrection value, with air humidity, the temperature in tunnel, tunnel length, width and height and shape, lamp group arrangement height
Etc. related；
Note: PWM in formulan、δ、N、n、EU、EN+1Simultaneously it is the related value of tunnel exit to K or is simultaneously tunnel portal
Related value.
Illustrate: δ >=5 or when δ≤- 3 start to adjust the brightness of gradual change lamp group, | ED-EN|1| value is bigger, and gradual change lamp group illumination is strong
Degree (or brightness) is bigger, and intensity of illumination adjusts corresponding different according to the difference of δ (i.e. the change rate of intensity of illumination in the unit time)
| E0-KN|1| it is adjusted with the relation curve of PWM controlling value (duty cycle percentage), which is above-mentioned gradual change lamp group
The curve that brightness regulation formula is drawn.
Wherein,The change rate of intensity of illumination i.e. in the unit time, value, which is positive, indicates that intensity of illumination is greater than outside tunnel
Intensity of illumination in tunnel, i.e. daytime period, value are negative when indicating that intensity of illumination is less than intensity of illumination, i.e. night outside tunnel outside tunnel
Section indicates that intensity of illumination is consistent inside and outside tunnel, does not need to open gradual change lamp group, as 3≤δ≤5, inside and outside tunnel when value is 0
Intensity of illumination difference in change does not need to open gradual change lamp group away from little yet；When δ >=5 or δ≤- 3, intensity of illumination becomes inside and outside tunnel
It is larger to change gap, needs to open gradual change lamp group, and by the intensity of illumination of PWM controlling value (duty cycle percentage) control gradual change lamp group
Size.
It include multiple lighting apparatus, model and quantity in the tunnel exit gradual change lamp group and tunnel portal gradual change lamp group
Selection, need to meet the required maximum light intensity value of the present invention, and suitably there are surpluses.
Whole device of the present invention can add on original tunnel illuminating system, and also alternative original tunnel illuminating system exists
Illumination functions in the gradual change distance of selection.
Working principle of the present invention are as follows: the outer optical sensor of optical sensor, tunnel exit in tunnel exit, in tunnel portal
Intensity of illumination inside and outside optical sensor and the outer optical sensor real-time monitoring tunnel of tunnel portal, while monitoring data being transmitted
To control unit, control unit is by data analysis (gradual change lamp group PWM controlling value is figured out according to the formula according to monitoring data)
Afterwards, output control signal is respectively to tunnel exit gradual change controlling on lamp group device and tunnel portal gradual change controlling on lamp group device, and then controls
The switch and brightness regulation of tunnel exit gradual change lamp group and tunnel portal gradual change lamp group；
Compared with prior art, the present invention according in tunnel exit and entrance external environment and tunnel intensity of illumination difference and
It changes, and the freeway tunnel lamp group of certain distance brightness of illumination gradual change is arranged in tunnel exit and in entrance, makes to drive
For member when crossing-river tunnel, eyes can gradually adapt to apparent light and shade variation inside and outside tunnel, shorten dark adaptation and light adaptation
Time, improve the sighting distance of driver, reduce stimulation of the mutation of illumination brightness to driver, ensure the friendship of freeway tunnel
Logical safety.
Example of the invention is explained in detail above in conjunction with embodiment, but the present invention is not limited to examples detailed above,
Within the knowledge of a person skilled in the art, it can also make without departing from the purpose of the present invention
Various change also should be regarded as protection scope of the present invention.
