Mobile Fire Detection Robot for Outdoor Zone Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire protection systems in large outdoor areas face challenges due to the limitations of stationary fire detectors, which are unreliable in harsh environmental conditions and require extensive installation, leading to potential blind spots and delayed fire detection, especially in areas with high fire risks. Additionally, existing systems rely heavily on user intervention, making them error-prone and time-consuming.
Innovation Solution
A fire protection robot system that autonomously navigates along a predefined or dynamically adjusted path using a control unit, equipped with fire sensors and communication units to detect fires and trigger firefighting devices, reducing the need for manual intervention and enhancing detection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stationary fire detectors are installed in large outdoor areas, then fire detection coverage is improved, but installation complexity and cost increase significantly
Solution Approach 1:
The large outdoor area is divided into multiple fire protection zones, each monitored by a mobile robot that sequentially visits different zones. This segmentation approach replaces the need for comprehensive stationary detector installation across the entire large area, reducing installation complexity while maintaining detection coverage through systematic zone-by-zone monitoring.
2Reliability
If stationary fire detectors are used in outdoor areas, then fire detection is enabled, but detection reliability deteriorates due to environmental influences
Solution Approach 1:
The system employs a mobile robot that dynamically moves through different outdoor locations rather than using fixed stationary detectors. This dynamic approach allows the robot to seek shelter or adjust its position when environmental conditions like rain or fog interfere with detection, thereby maintaining detection reliability despite harsh outdoor conditions.
3Ease of operation
If users manually monitor and respond to fire incidents, then fire protection actions can be initiated, but response time increases and errors occur
Solution Approach 1:
The mobile robot is equipped with autonomous capabilities to detect fire incidents, navigate to the incident location, and trigger fire protection devices without requiring continuous manual user intervention. The robot independently processes detection data, determines navigation paths, and executes fire suppression actions, dramatically reducing response time and eliminating human error while maintaining operational simplicity through centralized monitoring.
4Ease of manufacture
If fixed fire sensors with limited aperture angles are used, then installation is simplified, but detection range is reduced creating blind spots
Solution Approach 1:
The mobile robot serves multiple functions: it acts as a detection platform with sensors, a navigation system that moves to optimal detection positions, and a communication hub. This multi-functional design allows the use of simpler sensors with limited aperture angles on the robot, while the robot's mobility compensates for the limited sensor range by physically moving to cover the entire fire protection zone, eliminating blind spots without requiring complex fixed sensor installations.
