Aircraft Cargo Fire Detection With Automated Remedial Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft fire detection systems in unoccupied compartments rely heavily on manual crew intervention for assessing and responding to fire alarms, lacking integration with other onboard systems to provide automated support and accurate remedial actions.
Innovation Solution
A holistic fire detection system integrating fire detectors, monitoring systems, cargo tracking, aircraft control systems, and display devices to provide automated assessment and recommended remedial procedures to the cockpit crew based on comprehensive data analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual crew intervention is used for assessing and responding to fire alarms, then the system structure remains simple, but the response time and decision-making efficiency are reduced
Solution Approach 1:
The patent combines multiple independent systems (fire detection, cargo monitoring, aircraft control, navigation) into an integrated fire detection system that automatically shares data and coordinates responses, reducing the time needed for crew assessment and decision-making
Solution Approach 2:
The system enables automatic self-assessment of fire alarms through the system control that evaluates fire warning data, cargo data, and aircraft status data without requiring manual crew intervention, and automatically generates recommended remedial procedures
2Productivity
If automated assessment and remedial procedures are implemented, then crew response efficiency is enhanced, but the device complexity increases
Solution Approach 1:
The system control serves multiple functions: it assesses fire warnings, analyzes cargo data, evaluates aircraft status, generates remedial procedures, and coordinates with various aircraft systems, allowing a single component to handle diverse tasks that improve overall response efficiency
Solution Approach 2:
The system continuously monitors fire warning data, cargo data, and aircraft status data, using this feedback to automatically assess situations and generate appropriate remedial procedures, creating a closed-loop control system that enhances response efficiency
3Measurement precision
If comprehensive data integration from multiple systems is performed, then the accuracy of remedial action recommendations is improved, but the loss of information processing increases
Solution Approach 1:
The system extracts only the critical and relevant data from each integrated system (fire warning data, cargo data, aircraft status data) that is necessary for assessing fire alarms and generating remedial procedures, filtering out unnecessary information to reduce processing load while maintaining assessment accuracy
Data Source
AI summary
A fire detection system for monitoring an aircraft compartment and supporting a cockpit crew with taking remedial action in case of a fire alarm with a fire detector within the compartment; a monitoring system within the compartment to provide live monitoring data on cargo; a cargo tracking system configured to provide cargo data of the cargo; an aircraft control system configured to provide aircraft status data; a system control configured to assess a fire warning data, the cargo data and the aircraft status data and to provide a recommended remedial procedure based on the assessment in case the fire detector raises a fire alarm at least in an affected portion of the compartment; and a display device configured to display the live monitoring data and the recommended remedial procedure to the cockpit crew in case of a fire alarm
