Method for redundancy of multi-screen display function of display-control console

The invention provides a method for redundancy of a multi-screen display function of a display-control console. The method specifically includes: arranging a display link which comprises a computing unit, display modules, a switch unit and a display screen, wherein the computing unit can support multiple display signals, the display modules are connected with the computing unit, the switch unit is connected with the display modules, and the display screen is connected with the switch unit; arranging a monitoring link which comprises a monitoring chip connecting the computing unit with the switch unit; displaying normally, wherein half links of the display modules work normally at most while other links are dormant; when one display module is in a failure, positioning a failed point and cutting off a corresponding power supply link by the monitoring chip, controlling other display modules to add working links at the same time, and wakening a dormant CPU core. Compared with the prior art, the method has the advantages that a redundancy function is realized while stability in working of a host, safety and reliability in information and effectiveness in energy consumption saving are guaranteed, and the method is high in practicability and easy for popularization.
