Integrated system and method for automatically regulating luminance after LED display screen gets out of control

Abstract

Provided are an integrated system and method for automatically regulating luminance after an LED display screen gets out of control. The system comprises a set of LED display units, a control computer and a set of wireless communication instruments; the control computer sends control and configuration commands to all the LED display units in a periodic mode; the control computer is in real-time wireless communicated with the LED display units through the communication instruments; LED display screen safety luminance automatic regulation software modules are embedded into all the LED display units, and by monitoring the operation state of a signal automatic identification control system from the control computer, a safety luminance regulation mode or a normal work mode is started correspondingly. The LED display units analyze control signals, and when the control signals are normal, the LED display units are driven to work and receive various types of configuration and control; when the control signals are abnormal, the LED display units enter the self safety protection state, and actively regulate the self luminance and the work state, therefore, traffic accidents and light pollution caused by high luminance when the LED display screen gets out of control can be effectively avoided, and other relative problems are resolved.

Description

technical field [0001] The invention relates to an integrated system and method for an LED display screen that can turn into a self-safe working state and actively adjust its own brightness when it is out of control. Background technique [0002] LED display is a new type of information display media that developed rapidly in the world in the late 1980s. It uses dot matrix modules or pixel units composed of light-emitting diodes to form a display screen. It has high reliability, long service life, strong environmental adaptability, and low price. With the characteristics of high performance ratio and low cost of use, in just a few decades, it has rapidly grown into the mainstream product of flat panel display, and has been widely used in the field of indoor and outdoor information display. [0003] In recent years, my country's LED display industry has formed a number of backbone enterprises with a certain scale after several years of development. While my country's LED dis...

Problems solved by technology

[0005] However, the LED display unit may also lose control for some reason, so that the display screen may maintain extremely high brightness even at night, which is a great safety hazard for night drivers, and traffic accidents caused by it are also heard from time to time.
