Abstract
The utility model discloses a light-controlled LED display screen. The light-controlled LED display screen is characterized by comprising a light sensor, a data acquisition module, a data processing module, a data transmission module and an LED display screen control system. The light sensor which is arranged on the surface of the LED display screen is used for detecting external light signals. The data acquisition module acquires light sensor signals and transmits the signals to the data processing module for processing. The data processing module processes the signals and further sends control signals out. The control signals are sent to the LED display screen control system through the data transmission module. According to the received signals, the LED display screen control system controls the LED display screen to work in a way to automatically adjust the parameters in line with different external environments. The energy is thus saved.
Description
Technical field
The utility model relates to the LED display field, is 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 problem to be solved in the utility model 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 utility model adopts following technical scheme for solving the problems of the technologies described above:
A kind of light control LED display comprises 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, and described optical sensor is connected with data processing module by data acquisition module; Described data processing module is connected with the LED display control system by data transmission module, and the output of LED display control system is connected with LED display.
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 utility model is:
The utility model 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 utility model block diagram of system.
Embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is elaborated:
The utility model system architecture diagram 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.
