Embodiment Construction

[0026] Below in conjunction with accompanying drawing, structure and working process of the present invention will be further described.

[0027] Such as figure 1As shown, a LED display fault self-recovery control system includes a sending card, a receiving card, a signal distributor, a video processor, and a host computer. The host computer sends video signals to the video processor for processing, and the video processor Send the processed video signal to the sending card, the sending card packs and compresses the video signal and sends the compressed package to the receiving card through the signal distributor, the receiving card decompresses the received compressed package and performs image processing, and then sends the processed The video signal is sent to the LED display screen for display. The receiving card includes a processor, an address signal interface, a control signal interface, a data signal interface, and a programming interface. The processor includes a data...

Abstract

The invention discloses an LED display screen fault self-recovery control system. According to the control system, a storage unit is divided into two independent storage areas, one storage area is used for storing a program currently running on an LED display screen and display data of the LED display screen, the other storage area is used for storing a backup program, when the program currently running on the LED display screen has a fault or is updated, and the LED display screen automatically switches to the other storage area so that the backup program can run and the display data can be stored. The control system carries out automatic switching on the programs, a receiving card can be replaced without powering off the whole LED display screen, normal work of the LED display screen is not influenced, and the problems that in the prior art, an LED display screen control system cannot be updated on line when the programs are updated, and cannot recover by itself when having a grogram fault or data fault are solved.

Description

technical field [0001] The invention belongs to the field of LED display screen control, in particular to an LED display screen failure self-recovery control system. Background technique [0002] In the rapid development of today's modern information society, large-screen display has penetrated from commercial applications such as public information display to consumer multimedia applications. With the development of broadband networks, digital multimedia content will occupy the mainstream in the information world, and new large-screen display devices will replace traditional TV sets as the center for people to enjoy information and multimedia content. [0003] LED display control system (LED Display Control System), also known as LED display controller, LED display control card. It is the core component of the LED display screen. It is mainly responsible for receiving the picture and video display information from the computer serial port or DVI interface, putting it into ...
