Emergency Exit Misuse Identification via Alarm Event Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency exits are often misused, leading to false alarms, damage, and resource wastage, making it challenging to distinguish proper from improper usage due to various influencing factors, resulting in costly and inefficient emergency procedures.
Innovation Solution
A rules-based emergency exit misuse identification system that utilizes cloud servers to store instructions for security systems to analyze data from sensors, classify burglar alarm events as delay or non-delay events, generate recommendations, and produce reports to prevent future misuse by determining door events and alarm cancellations within defined time periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If emergency exits are monitored with alarms to detect unauthorized use, then security and compliance are improved, but false alarms increase causing costly emergency procedures and resource wastage
Solution Approach 1:
The system performs preliminary classification of alarm events into delay and non-delay categories before triggering full emergency procedures. By analyzing door open/close events and alarm cancellation patterns within defined time periods, the system预先 determines whether to initiate emergency responses, preventing resource wastage from false alarms while maintaining security monitoring.
2Loss of energy
If strict monitoring rules are applied to emergency exits to prevent misuse, then false alarms are reduced, but legitimate emergency usage may be restricted
Solution Approach 1:
The system dynamically adjusts monitoring strictness based on real-time event patterns. By implementing configurable time periods and event thresholds that can be modified based on observed usage patterns, the system adapts its response criteria to distinguish between misuse and legitimate emergency usage, maintaining ease of operation for true emergencies while reducing false alarms.
3Measurement precision
If comprehensive data collection from sensors is implemented to analyze emergency exit usage, then accuracy of misuse identification is improved, but system complexity increases
Solution Approach 1:
The system extracts only the critical data elements needed for misuse identification from sensor outputs, such as door open/close events, alarm cancellation events, and timestamps. By focusing on essential parameters rather than collecting all possible sensor data, the system achieves high measurement precision for misuse identification while keeping the data processing system relatively simple and manageable.
4Measurement precision
If multiple factors influencing emergency exit use are monitored to distinguish proper from improper usage, then identification accuracy is improved, but difficulty of detection and measurement increases
Solution Approach 1:
The system segments the analysis of multiple influencing factors into distinct, manageable event types such as door open events, door close events, and alarm cancellation events. Each event type is detected and measured independently with specific criteria, then combined through logical rules to determine overall usage classification. This segmentation reduces the difficulty of detecting and measuring each individual factor while maintaining high overall identification accuracy.
