Controller redundancy for a display system

Abstract:

A display system comprises a plurality of displays each comprising an array of light-emitting elements to display a corresponding message, a primary controller that controls the array of light-emitting elements of each display to control the content of each message, a communication network to transmit control signals from the primary controller to the displays, a remote manager in communication with the primary controller via a primary manager communication link, and a redundant controller configured and able to control the array of light-emitting elements of each display to control the content of each message if it is determined that there is a malfunction of the primary controller, an interruption in the communication network between the primary controller and at least one of the displays, or an interruption in the primary communication link.
