Public Address Event Log Auditing for Message Delivery Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current public address systems lack a mechanism to verify that predefined actions are properly executed during events, such as emergencies, leading to potential faults in message delivery and evacuation instructions.
Innovation Solution
A system and method for public address system action auditing that includes a computing device to compare an event log with a predefined configuration file, generating a report to verify that the system's actions align with predefined settings, identify faults, and provide troubleshooting suggestions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a public address system is used to emit noises for announcements and emergencies, then the system can provide audible warnings and information to occupants, but there is no mechanism to verify that the system actually executed the predefined actions during events
Solution Approach 1:
The patent implements a feedback mechanism by comparing the event log (actual system actions) with the predefined configuration file (expected actions). This closed-loop verification ensures that the public address system executed its predefined actions correctly during events, providing reliability without significantly increasing operational complexity.
Solution Approach 2:
The system performs preliminary action by pre-defining configuration files that specify expected actions for various events. These configuration files are prepared in advance, allowing the auditing mechanism to verify whether the system executed the correct predefined actions when events occur, thereby ensuring message delivery reliability.
2Illumination intensity
If the public address system emits noises over large areas at high volume, then emergency warnings can be heard clearly, but faults in message delivery may go undetected
Solution Approach 1:
The auditing system provides feedback by systematically comparing what the system was supposed to do (predefined configuration) with what it actually did (event log). This verification mechanism ensures precise detection of any deviations in message delivery, regardless of the audible intensity of the emergency warnings.
Solution Approach 2:
The patent introduces an intermediary auditing mechanism that acts as a mediator between the public address system's operations and the verification process. The event log serves as an intermediary record that captures actual system actions, allowing for accurate measurement and verification without affecting the system's audible output capabilities.
3Adaptability or versatility
If the system is designed to perform multiple functions (announcements, music, emergencies), then the public address system is versatile, but it becomes difficult to audit and verify specific actions during different event types
Solution Approach 1:
The patent applies segmentation by dividing the auditing process into distinct components: event logs that record actual actions, predefined configuration files that specify expected actions for different event types, and a comparison mechanism. This segmented approach allows the system to handle multiple functions (announcements, music, emergencies) while making each action type auditable and verifiable through structured comparison.
Solution Approach 2:
The auditing mechanism itself is designed with universality, using a single comparison framework that can verify actions across all event types and system functions. The predefined configuration files and event log structure accommodate multiple functions (announcements, music, emergencies) within a unified auditing system, making verification straightforward regardless of the specific event type.
