Abstract

The invention discloses a light-controlled LED display screen control system, which comprises a light sensor, a data acquisition module, a data processing module, a data transmission module and LED display screen control systems, wherein two LED display screen control systems are arranged, and one of the LED display screen control systems is a major LED display screen control system and the other one is a standby LED display screen control system; the major LED display screen control system works when an LED display screen is normal in data transmission, and the standby LED display screen control system works when the LED display screen is abnormal in data transmission. The light-controlled LED display screen control system can rapidly switch to the standby LED display screen control system so as to support continuous work; therefore, the utilization rate of the LED display screen is effectively improved.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to a light control LED display screen control system. Background technique [0002] More and more LED manufacturers at home and abroad continue to launch their own LED displays. As far as the current situation is concerned, the LED display screens on the market have relatively single functions. Most of the display screens manually control the brightness, grayscale and other parameters of the display screen according to the different external environments. Although some companies in China have introduced LED display screens that automatically control parameters, most of these display screens add timers to the host computer system and run for a certain period of time to change parameters. Although this system makes up for the existing However, there is still a certain gap from a truly energy-saving and environmentally friendly display system. [0003] LED display control system (L...
