Problems solved by technology
Since the display devices are independent of each other, when a certain display device fails, the display interface it should provide may fail. If the display device with high importance in the system fails, the failure of the corresponding display interface may be will seriously affect the reliability of the system

The invention discloses a distributed display method, which is applied to N display devices, including: reading its own hardware code when starting; wherein, the hardware codes of each display device are different from each other, and different hardware codes correspond to different priority; determine the corresponding priority according to the read hardware code as the current priority of its own display module and communication module; send its own life signal and display module priority to the remaining N-1 display devices; when judging When the life signal of any display module whose priority is higher than that of its own display module is abnormal, and the preset switching condition is met, switch the priority of its own display module and communication module to the priority of the abnormal display device. display modules have the same priority. By applying the scheme of the present invention, the reliability of the system can be improved. The present invention also provides a distributed display system, equipment and computer-readable storage medium, which have corresponding effects.
Description
technical field [0001] The present invention relates to the technical field of industrial control, in particular to a distributed display method, system, equipment and computer-readable storage medium. Background technique [0002] In industrial control and rail transit, there are usually multiple display devices for human-computer interaction, and each display device works independently to provide its own display interface. That is, each display device independently provides operation and information display functions. [0003] However, since different display devices provide different display interfaces, each display device has different importance. For example, in the on-board system of rail transit, the importance of the display device that provides the on-board signal display interface is much higher than that of the display device that provides the monitoring screen. Since the display devices are independent of each other, when a certain display device fails, the dis...
