Fault early warning system for LED display screen

Abstract

The invention discloses a fault early warning system for an LED display screen, which comprises a signal receiving module, a detecting module, a processing module, a display module and a warning module, wherein the signal receiving module is used for receiving target control signal data and generating target display signal data of the LED screen; the detecting module is used for detecting actual display signal data of the LED screen in a real-time manner; the processing module is provided with a preset input end and an analysis sub-module and used for presetting structural data of the LED screen, carrying out comparative analysis on the target display signal data and the actual display signal data, generating display comparative analysis data of the LED screen according to structural data of the LED screen, and sending to the display module for displaying; and the processing module can further generate warning signal data and sending to the warning module for warning when the target display signal data is different from the actual display signal data. The fault early warning system can provide the fault early warning, find fault hidden troubles of the LED screen in time, actively maintain the LED screen and prevent faults in advance.

Description

technical field [0001] The invention relates to a lighting device, in particular to an LED display screen fault warning system. Background technique [0002] With the holding of large-scale events such as the World Expo and the Asian Games in my country, it has provided a good display platform for China's LED industry. LED displays have played a more important role in large-scale events and important occasions. The reliability and stability of display applications are extremely important. [0003] In the prior art, among the failures of LED screens, problems caused by aging account for the vast majority, such as loose solder joints and loose signal connection lines. These failures are gradually developed from occasional failures to continuous failures. In the existing LED display fault detection technology, the fault is generally detected and repaired after the fault occurs, and the sporadic instability of the components of the LED display cannot be found in the early stage...

AI Technical Summary

Problems solved by technology

In the existing LED display fault detection technology, the fault is generally detected and repaired after the fault occurs, and the sporadic instability of the components of the LED display cannot be found in the early stage of the fault, so that the corresponding parts cannot be repaired in advance. Maintenance, but can only do passive maintenance work, causing the LED display to be unstable during use in some large-scale activities or important places, and prone to use interruptions
