Remote Display Control Board Failure Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic displays in advertising, information, and point of sale applications often experience downtime due to failures, leading to lost revenue and ineffective communication, as existing systems require user intervention to address issues.
Innovation Solution
A system and method for monitoring remote electronic displays for failures, utilizing heartbeat signals, status messages, LED light signals, and network communications to make near-instantaneous changes and reduce or eliminate downtime without user intervention, by simulating power button presses and power supply connections through the system control board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual user intervention is used to address display failures, then the system structure remains simple, but downtime increases and revenue is lost
Solution Approach 1:
The system enables self-service by allowing the control board to automatically detect failures through heartbeat signals and status messages, then autonomously execute recovery sequences including simulating power button presses and reinitializing components without requiring human intervention, thereby maintaining continuous operation
Solution Approach 2:
The system implements preliminary action by continuously monitoring heartbeat signals and status messages before failures manifest, enabling early detection and automatic initiation of recovery sequences that switch to backup video players or reinitialize components proactively to prevent complete system downtime
2Loss of time
If automated monitoring and recovery systems are implemented, then downtime is reduced, but device complexity increases
Solution Approach 1:
The system implements feedback by continuously receiving and analyzing heartbeat signals and status messages from display components, comparing them against expected operational parameters, and automatically triggering recovery sequences when deviations indicate failures, thereby minimizing downtime through real-time monitoring and response
Solution Approach 2:
The control board serves multiple functions including normal display control, failure detection through monitoring, automatic recovery execution, and simulation of physical user actions, consolidating these diverse functions into a single multi-functional component that reduces overall system complexity despite the enhanced automation capabilities
3Measurement precision
If continuous monitoring of heartbeat signals and status messages is performed, then failure detection precision improves, but energy consumption increases
Solution Approach 1:
The system implements periodic action by monitoring heartbeat signals and status messages at regular intervals rather than continuously, checking for failures at predetermined frequencies that provide sufficient detection accuracy while allowing the system to enter lower-power states between monitoring cycles, thereby balancing precision with energy efficiency

AI summary
A system and method for addressing failures in electronic display assemblies is provided. Each of a plurality of electronic display assembles include an electronic display, one or more components for operating the electronic display assembly, and a control device. A network operations center is located remote from, but in electronic communication with, each of the electronic display assembles. If the control devices determine that any of the components are not operating properly, the control device is configured to remove the power supplied to the components, wait a predetermined amount of time, and resume applying power.
