Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forest fire early detection systems face challenges such as inefficiency at night, high costs, and environmental impact due to satellite-based monitoring, and time-consuming manual installation of sensors in difficult-to-access areas.
Innovation Solution
A method and system for a forest fire early detection system that uses a network of inexpensive, self-sufficient terminals with communication and flight control devices, allowing for rapid and cost-effective installation and configuration. The terminals are scattered densely throughout the monitoring area, with their exact positions unknown, and communicate via LoRaWAN or satellite networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite-based monitoring is used for forest fire detection, then detection coverage is improved, but cost and environmental impact increase
Solution Approach 1:
The patent divides the monitoring system into multiple ground-based terminal units distributed throughout the forest area, replacing the single satellite-based approach. Each terminal independently monitors its local area, collectively providing comprehensive coverage without requiring expensive satellite infrastructure.
Solution Approach 2:
The patent employs inexpensive terminal units that can be easily deployed and replaced, contrasting with the costly satellite system. These terminals use simple sensors and communication modules that are economically viable for large-scale deployment in remote areas.
2Manufacturing precision
If manual installation of sensors is used in difficult-to-access areas, then installation precision is improved, but installation time increases
Solution Approach 1:
The terminal units are designed to be self-deploying through aerial dispersal, eliminating the need for manual installation in difficult-to-access areas. The units automatically activate and integrate into the monitoring network upon deployment, providing both speed and adequate positioning precision.
3Measurement precision
If terminals are manually arranged in forest areas, then position accuracy is improved, but installation cost increases
Solution Approach 1:
The terminal units automatically determine their own positions using GPS or other location systems after aerial deployment. This self-positioning capability eliminates the need for manual placement while maintaining sufficient position accuracy for effective fire detection and localization.
