Become, such as increase or reduce, then easily causing human eye discomfort, passes through the inspection of the luminous intensity of real-time detecting advertisement machine local environment
It surveys, and is compared with first environment luminous intensity when optimal brightness show value, realize the tune to currently detected ambient light intensity
It is whole, to adapt to the optimum reelability quality of human eye viewing.
Further, step S43 includes：If the second environment luminous intensity is less than the first environment luminous intensity, subtract
The backlight illumination of the small liquid crystal display.
When detecting that second environment luminous intensity is less than first environment luminous intensity, reduce the backlight illumination of liquid crystal display,
It avoids the backlight of the liquid crystal display in darker environment brighter and causes dazzling discomfort.
Specifically as shown in fig. 6, within a preset range, ambient light intensity is bigger, the backlight illumination of liquid crystal display is bigger；Ring
Border luminous intensity is smaller, and the backlight illumination of liquid crystal display is smaller, and when environmental light brightness is 0, liquid crystal display passes through backlight
Brightness is maintained at certain brightness suitable for human eye viewing.
Based on 3rd embodiment, the present invention also proposes the fourth embodiment of the method for intelligent regulator brightness, as shown in fig. 7,

Second infrared detections of sensor current detection determine the second man-machine distance between user and advertisement machine, if described second
Man-machine distance is greater than the described first man-machine distance, then increases the backlight illumination of the liquid crystal display.Since user is seeing extensively
After announcement machine, it may walk about, such as close to advertisement machine either far from advertisement machine, then man-machine distance will change, if
The backlight of liquid crystal display is not adjusted, and human eye viewing may be caused uncomfortable, therefore, infrared sensor of the human body real-time detection human body
Infrared signal judges man-machine distance according to the power of signal, and as can be seen from the above embodiments, corresponding optimal brightness show value is
One man-machine distance, it is assumed that the first man-machine distance is 5 meters, then, when user close to advertisement machine to 3 meters when, if current liquid crystal
The backlight illumination of display screen does not adjust, then human eye can think that advertisement machine is excessively bright, it is dazzling, cause human eye uncomfortable；When user is separate
When advertisement machine is to 10 meters, if the backlight illumination of current liquid crystal display does not adjust, then human eye can think that advertisement machine is excessively dark, hold
The advertising information of display is not seen easily, and therefore, infrared sensor of the human body real-time detection human infrared signal determines user and advertisement
The second man-machine distance between machine obtains crystal display screen by the comparison between the first man-machine distance and the second man-machine distance
The adjustment mode of backlight illumination, when the second man-machine distance be greater than first it is man-machine apart from when, human eye can think that advertisement machine is excessively dark, because
This, increases the backlight illumination of crystal display screen, has reached best viewing effect.
Further, the step S50 further includes：
If the second man-machine distance is less than the described first man-machine distance, the backlight for reducing the liquid crystal display is bright
Degree.
In the present embodiment, detect the second man-machine distance it is man-machine less than first apart from when, illustrate the closer advertisement of user
Machine needs to reduce the backlight illumination of the liquid crystal display.
It is specific as shown in figure 8, in the range of preset range is 20 meters, man-machine apart from smaller, liquid crystal display passes through back
The brightness of light is smaller, and when man-machine distance is 0, the backlight illumination of liquid crystal display still keeps certain brightness, sees convenient for human eye
It sees；Man-machine distance is bigger, and the backlight illumination of liquid crystal display is bigger, and human eye is enabled to watch liquid crystal display；Exceeding
In 20 meters of preset range, illustrate that human body has exceeded in preset range, main control module controls backlight control module and closes backlight, closes
Liquid crystal display, therefore, the brightness that liquid crystal display passes through backlight are 0, reach energy saving purpose.
Based on first embodiment, the present invention proposes the 5th embodiment of the method for intelligent regulator brightness, as shown in figure 9, step
After rapid S40, the method for intelligent regulator brightness further includes：
Step S70 determines the advertisement based on the third infrared detections of the infrared sensor of the human body current detection
