Abstract
The invention discloses a light ray control light-emitting diode (LED) display screen. The light ray control LED display screen is characterized by comprising an optical sensor, a data collecting module, a data processing module, a data transmission module and an LED display screen control system, wherein the optical sensor is installed on the surface of the light ray control LED display screen, the optical sensor is used for detecting a light ray signal of the outside, the data collecting module is used for collecting an optical sensor signal, the optical sensor signal is transmitted by the data collecting module to the data processing module to be processed, a processed signal is obtained, a control signal is sent to the LED display screen control system through the data transmission module, and the light ray control LED display screen control system is used for controlling the LED display screen to automatically adjust parameters to work in different external environments. Energy sources are saved.
Description
Technical field
The present invention relates to the LED display field, be specifically related to a kind of LED display of light control.
Background technology
Increasing LED manufacturer constantly releases the LED display of own company both at home and abroad.With regard to current position analysis, the LED display function ratio on the market is more single, and most of display screens all are the differences according to external environment, manually controls the parameter such as brightness, gray scale of display screen.Though the domestic LED display that also has some companies to release automatic control parameter, but this display screen is to add timer in master system mostly, the operation regular hour changes parameter, though this system has remedied the deficiencies in the prior art to a certain extent, but the display screen system of the real energy-conserving and environment-protective of distance also has a certain distance.
Summary of the invention
Technical matters to be solved by this invention is: the LED display that a kind of light control is provided, automatically regulate the parameters such as brightness, gray scale of display screens according to extraneous light different, solve LED display and can not change the problem that parameter is moved in real time automatically, improve the LED display intelligent level, saved the energy.
The present invention adopts following technical scheme for solving the problems of the technologies described above:
A kind of light control LED display is characterized in that: comprise optical sensor, data acquisition module, data processing module, data transmission module, LED display control system; Wherein, optical sensor is installed in the surface of LED display, for detection of extraneous light signal; The data collecting module collected photosensor signal, and transfer to the data processing module processing; Data processing module compares according to the signal and the predefined value that receive, judges extraneous light environment, and sends control signal according to judged result, by data transmission module control signal is sent to the LED display control system; The LED display control system is according to the work of the signal controlling LED display of receiving.
Described LED display control system adopts Serial Port Line or netting twine to be connected with data transmission module; Described optical sensor is the sunshine sensor; Described data processing module comprises at least a among single-chip microcomputer, FPGA, the ARM.
Compared to existing technology, the beneficial effect that has of the present invention is:
The present invention adopts the sunshine sensor, by the signal of the extraneous light of real-time collection, the control LED display is moved under different parameters automatically, regulates brightness, gray scale etc. automatically, improved the intelligent level of display screen, under the strong environment of extraneous light, improve brightness, suitable human eye is watched, under the dark environment of extraneous light, reduce brightness of display screen, saved electric energy, reduced the light pollution of LED display simultaneously.
Description of drawings
Fig. 1 is the block diagram of system of the present invention.
Embodiment
Be elaborated below in conjunction with the technical scheme of drawings and Examples to invention:
System architecture diagram of the present invention comprises optical sensor, data acquisition module, data processing module, data transmission module, LED display control system as shown in Figure 1; Wherein, optical sensor is installed in the surface of LED display, detect extraneous light signal, the data collecting module collected photosensor signal, and transfer to data processing module and handle, data processing module compares according to the signal and the predefined value that receive, judge extraneous light environment, and send control signal according to judged result, by data transmission module control signal is sent to the LED display control system, the LED display control system is according to the work of the signal controlling LED display of receiving.
Described LED display control system adopts Serial Port Line or netting twine to be connected with data transmission module; Described optical sensor is the sunshine sensor; Described data processing module comprises at least a among single-chip microcomputer, FPGA, the ARM.
The present embodiment data processing module adopts 51 series monolithics, and concrete model is AT89C51, and the course of work of the present invention is as follows:
AT89C51 compares data acquisition module block signal and the predefined value that receives, and the difference after will comparing is input to the LED display control system, the LED display control system is according to the signal value of receiving, select the parameter of coupling to be sent to LED display, realize LED display adjusting parameter operation automatically under the different light rays environment.
