System and method for monitoring a signage system of a transit vehicle
First Claim
1. An electronic monitoring system comprising:
- a pixel array comprising a plurality of pixels;
wherein the pixel array comprises a plurality of printed circuit boards (PCBs), each PCB providing a sub-array of the pixel array; and
an embedded controller coupled to the pixel array operable to;
analyze the pixel array as a single matrix; and
determine a number of malfunctioning pixels in at least one of;
a row of the single matrix, wherein the row spans more than one PCB of the plurality of PCBs; and
a column of the single matrix, wherein the column spans more than one PCB of the plurality of PCBs; and
transmit diagnostic information to a controller, the diagnostic information comprising information related to the determined number.

Abstract
A sign-monitoring system includes at least one electronic sign and a controller comprising a processor and memory. The electronic sign includes a pixel array, the pixel array including a plurality of pixels. The electronic sign further includes an embedded controller coupled to the at least one electronic sign. The embedded controller develops diagnostic information for the at least one electronic sign, the diagnostic information including information related to a number of malfunctioning pixels in the plurality of pixels. The controller is communicably coupled to the embedded controller and receives at least a portion of the diagnostic information from the embedded controller. In addition, the controller assesses the at least a portion of the diagnostic information to develop health information. The assessment involves evaluating the information related to the number of malfunctioning pixels.
