To center processor, while infrared high-definition camera shoots the people in effective range to camera by face recognition software and carries out
It quickly captures, and the number of candid photograph is fed back into center processor, the data handled well are respectively transmitted to LED by center processor
Brightness processed module and LED power switch process module；
(1) LED luminance processing module is analyzed by data: when light and shade variation occurs for LED playing environment brightness, LED screen
Display state change therewith, i.e., analog quantity (brightness, colour temperature, contrast, color saturation) is all best by what is be pre-designed
Viewed status is changed therewith, and the best viewing effect of spectators is reached with this.
(2) it LED power switch process module: is arrived by being captured in face identification functions infrared high-definition camera certain time
Number, calculate total number of persons through center processor, total number of persons feeds back to power switch processing module, power switch processing
Module compares to decide whether to continue to play or into shutdown mode according to the number that the number of setting and statistics are come.
It is an advantage of the current invention that passing through the light-sensitive device and infrared high-definition camera that are mounted on the open air LED large-size screen monitors surrounding
It is transferred to center processor after acquisition data and carries out analysis comparison, then data are conveyed to corresponding brightness processed module and are opened
Control processing module is closed, by this 2 processing modules respectively to the analog quantity of LED screen (brightness, contrast, color saturation, color
Temperature) and power switch be automatically adjusted and control, thus effectively raising the open air LED screen ornamental value and stability, and
Energy consumption is greatly reduced while also extending the service life of LED screen, to the more convenient and fast management mode of LED screen manager offer and extensively
Big spectators obtain the picture of more aesthetic feeling, while being greatly reduced the management cost and operation cost of LED screen.
Detailed description of the invention
Fig. 1 is the functional block diagram of LED outdoor-screen intelligence control system of the present invention.
Specific embodiment
With reference to the accompanying drawings and detailed description, to LED outdoor-screen intelligence control system of the invention and control method
It is described in further detail.
It include be mounted on LED outdoor-screen surrounding more as shown, LED outdoor-screen intelligence control system of the invention
A light-sensitive device and the camera for being mounted on LED outdoor-screen surrounding, described light-sensitive device can acquire LED screen surrounding certainly in real time
The illumination of right light；LED outdoor-screen is connected with LED luminance processing module and LED switch processing module, and light-sensitive device and camera are equal
It connects on the same center processor, center processor includes the information acquisition module being connected on internal lan and information
Release module；Center processor is also directly connect with LED luminance processing module and LED switch processing module, center processor energy
Enough data acquired to light-sensitive device and camera handle and the data of acquisition are transferred to brightness processed module and switch
Control processing module is automatically adjusted and controls to the analog quantity and power switch of LED screen.
Further, described camera is high definition camera, has recognition of face mould in high definition camera
Thus block makes it have face identification functions, described LED luminance processing module is can be (bright to LED screen progress analog quantity
Degree, contrast, color saturation, colour temperature) microprocessor that is controlled and finely tuned, described LED switch control module is LED electricity
The power supply of the control microprocessor of source switch, described LED switch control module and outdoor-screen is attached.
Its working principles are as follows:
After the power switch for opening the open air LED large-size screen monitors, the multiple light-sensitive device of the screen surrounding of the open air LED large-size screen monitors and infrared
High-definition camera is started to work respectively, and multiple light-sensitive devices start to incude natural light illumination at that time and the data feedback acquisition
To center processor, while infrared high-definition camera shoots the people in effective range to camera by face recognition software and carries out
It quickly captures, and the number of candid photograph is fed back into center processor, the data handled well are respectively transmitted to LED by center processor
Brightness processed module and LED power switch process module；
(1) LED luminance processing module is analyzed by data: when light and shade variation occurs for LED playing environment brightness, LED screen
Display state change therewith, i.e., analog quantity (brightness, colour temperature, contrast, color saturation) is all best by what is be pre-designed
Viewed status is changed therewith, and the best viewing effect of spectators is reached with this.
(2) it LED power switch process module: is arrived by being captured in face identification functions infrared high-definition camera certain time
Number, calculate total number of persons through center processor, total number of persons feeds back to power switch processing module, power switch processing
Module compares to decide whether to continue to play or into shutdown mode according to the number that the number of setting and statistics are come.
Such as: the camera of LED screen surrounding searches for the people in LED screen visual range in 5 minutes, and is known by face
Other function transfers data to center processor, if the number addition that all cameras search in 5 minutes is not above 100
People, for center processor according to the data transmission counted to power supply processing module, power module starts 1 minute shutdown shape of countdown
State, people of the camera still in search visual range in this 1 minute, power module moves back if number is more than 100 people at this time
Off-mode out, otherwise large-size screen monitors shut down after 1 minute, and camera is such at interval of the demographic's search of starting in 30 minutes
Power management can make the utilization rate of LED outdoor-screen reach maximization, especially be the flows of the people such as non-period on day off and the time after midnight
Rare situation, and the power consumption of LED outdoor-screen is all several myriawatts~tens myriawatts, and such power supply control not only reduces
The working strength of LED screen administrative staff, and more optimize the service efficiency of LED outdoor-screen, effective control reduces energy consumption.
