Abstract

The invention discloses an LED screen control system featuring diplonema redundancy fault-tolerance and an application method thereof. The system comprises a first video controller, a second video controller, a first video distributor, a second video distributor, a module control panel and an LED screen module; the first video controller and the first video distributor construct a first video channel, the first video channel is connected with a first video input port and inputs the signals into the first video input port, the second video controller and the second video distributor construct asecond video channel, the second video channel is connected with a second video input port and inputs the signals into the second video input port, the first video channel and the second video channel are mutually independent, a video detection processing module detects the video data of the first video channel and that of the second video channel in real time and carries out channel switch according to the detection result, thus ensuring the video data received by the module control panel to be normal and outputting normal signals to drive the LED screen module to display. The invention overcomes the poor fault-tolerance capacity of the existing LED screen control systems, long-time stable running of an LED screen can be realized by the method with higher practicability.

Description

technical field [0001] The invention relates to the technical field of LED display, and in particular to a dual-line redundant fault-tolerant LED display control method. It can be used to improve the reliability of the display system. Background technique [0002] Due to the promotion of the demand of the information dissemination industry, the demand for LED display screens is increasing. [0003] Most of the LED display screens are located in the harsh outdoor environment, and the data lines between the various components are prone to natural or man-made damage. Once such damage occurs, the receiving card will not be able to receive video data, and the corresponding display module will also be damaged. Just can't display image, then need manual intervention to repair in order to restore display, the self-adaptive performance of the system is relatively poor, therefore, prior art work reliability is relatively low. [0004] Redundancy refers to the repeated configuration ...
