Intelligent Evacuation System for Building Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smoke detection systems in buildings often fail to effectively guide individuals to safe evacuation routes during emergencies, leading to casualties due to confusion, poor visibility, and unfamiliarity with the building layout.
Innovation Solution
An intelligent evacuation system that uses sensory nodes to detect occupancy and evacuation conditions, determining and conveying safe evacuation routes through audible messages and integrating with emergency response centers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional smoke detectors are used to detect fires, then fire detection capability is provided, but individuals cannot effectively evacuate due to confusion, poor visibility, and lack of evacuation route information
Solution Approach 1:
The patent introduces an intermediary intelligent evacuation system that includes occupancy sensors, route determination algorithms, and communication devices. This intermediary system bridges the gap between fire detection and safe evacuation by providing real-time occupancy information and directing individuals to optimal evacuation routes, thereby preventing information loss about evacuation paths.
2Reliability
If no intelligent evacuation system is implemented, then device complexity is low, but individuals suffer casualties due to inability to evacuate effectively
Solution Approach 1:
The intelligent evacuation system is segmented into distinct functional modules: occupancy detection units, fire detection units, route determination processors, and communication devices. Each module performs a specific function, allowing the system to achieve high evacuation effectiveness while maintaining manageable complexity through modular design and clear separation of concerns.
3Measurement precision
If occupancy information is collected and processed to determine evacuation routes, then evacuation guidance accuracy is improved, but system complexity and processing requirements increase
Solution Approach 1:
The system employs self-service mechanisms where occupancy sensors automatically detect and report occupancy status, the processor autonomously determines optimal evacuation routes based on real-time data, and communication devices automatically disseminate route information to occupants. This automation reduces the need for complex manual intervention while maintaining high measurement precision and route determination accuracy.
Data Source
AI summary
A method includes reading a digital signal from a sensing device in an area of a structure, where the digital signal is configured to be present periodically. A trailing edge of the digital signal is determined. An analog signal from the sensing device is read, where the analog signal includes an output from a sensor included in the sensing device, and where the sensor is configured to detect an aspect of an environment. The analog signal is read after the trailing edge of the digital signal.
