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.
