Digital Signage Player Automated Fault Detection and Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital signage systems with limited hardware resources face challenges in monitoring abnormal playback and performing quick troubleshooting, often resulting in costly and inefficient on-site inspections due to frequent black screens and software instability.
Innovation Solution
A maintenance method that detects processor usage statuses, activates a screen analysis module to check for abnormal images, and automatically performs troubleshooting procedures, including restarting playback software when a black screen is detected, using a monitoring module, screen analysis module, and troubleshooting module within the digital signage player.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a digital signage player has limited computing power and memory size, then hardware cost is reduced, but the system becomes unstable and frequently experiences black screens and playback failures
Solution Approach 1:
The system performs preliminary actions by continuously monitoring processor usage and detecting abnormal conditions before complete system failure occurs. The monitoring module tracks CPU usage of playback processes, and when abnormal patterns are detected (such as sustained high usage or unresponsive processes), the system proactively triggers troubleshooting procedures including automatic restart, preventing complete playback failure and extending system reliability despite limited hardware resources.
2Reliability
If personnel are dispatched for regular on-site inspection to determine whether digital signage is functioning correctly, then system reliability is monitored, but labor cost and time consumption increase significantly
Solution Approach 1:
The system implements continuous feedback mechanisms through automated monitoring modules that track processor usage, playback status, and system health metrics. This feedback is processed in real-time to detect abnormalities, triggering automatic troubleshooting procedures. The closed-loop feedback system eliminates the need for manual inspection by providing continuous system state information and automatically responding to detected issues, thereby maintaining high reliability monitoring while eliminating time loss associated with on-site personnel dispatch.
Solution Approach 2:
The digital signage player performs self-diagnosis and self-repair through automated troubleshooting procedures. When the monitoring module detects playback abnormalities or black screen conditions, the system automatically executes predefined troubleshooting steps including process restart, log analysis, and system recovery operations. This self-service capability enables continuous reliability monitoring without requiring external personnel intervention, significantly reducing both labor costs and troubleshooting time.
3Productivity
If the playback software consumes excessive processor resources, then multimedia playback quality is maintained, but the system becomes unstable and crashes frequently
Solution Approach 1:
The system dynamically adjusts to processor resource consumption patterns by continuously monitoring CPU usage of playback processes. When the monitoring module detects that processor usage exceeds predetermined thresholds or displays abnormal patterns, the system dynamically responds by triggering troubleshooting procedures such as process restart or resource allocation adjustments. This dynamic monitoring and response mechanism enables the system to maintain stable multimedia playback performance while preventing crashes caused by excessive resource consumption, adapting to varying playback demands without compromising reliability.

AI summary
Maintenance methods of digital signage applied to a player of the digital signage are provided, wherein the player performs playback software to play multimedia information through the digital signage. The method includes the steps of: detecting processor usage statuses of one or more processes corresponding to the playback software; determining whether a predetermined condition is satisfied based on the processor usage statuses of the one or more processes; activating a screen analysis module to detect whether a screen image is abnormal in response to determining that the predetermined condition is satisfied; and activating a troubleshooting module to automatically perform an automatic troubleshooting procedure in response to the screen detection module detecting that the screen image is abnormal.
