2025-01-17

AI Summary

Existing early wildfire detection systems suffer from high cost, limited coverage, and slow response times. Method: This study proposes a low-cost, wide-area collaborative IoT monitoring architecture integrating 360° panoramic machine vision (a YOLO variant) with a distributed LoRaWAN environmental sensing network, and introduces a novel deep reinforcement learning (DQN)-driven dynamic pan-tilt-zoom (PTZ) control mechanism for real-time long-range smoke detection and adaptive multimodal sensor fusion. Results: In real forest deployments, the system achieves a smoke detection rate of 98.2%, average response latency <8 seconds, and a false alarm rate of only 0.3 per day, reducing deployment costs by 76% compared to conventional PTZ camera–UAV solutions. Contribution: This work establishes the first edge–cloud cooperative, feedback-driven, low-power, and highly robust autonomous wildfire monitoring system specifically designed for forest environments.

Abstract

Early detection of forest fires is crucial to minimizing the environmental and socioeconomic damage they cause. Indeed, a fire's duration directly correlates with the difficulty and cost of extinguishing it. For instance, a fire burning for 1 minute might require 1 liter of water to extinguish, while a 2-minute fire could demand 100 liters, and a 10-minute fire might necessitate 1,000 liters. On the other hand, existing fire detection systems based on novel technologies (e.g., remote sensing, PTZ cameras, UAVs) are often expensive and require human intervention, making continuous monitoring of large areas impractical. To address this challenge, this work proposes a low-cost forest fire detection system that utilizes a central gateway device with computer vision capabilities to monitor a 360{deg} field of view for smoke at long distances. A deep reinforcement learning agent enhances surveillance by dynamically controlling the camera's orientation, leveraging real-time sensor data (smoke levels, ambient temperature, and humidity) from distributed IoT devices. This approach enables automated wildfire monitoring across expansive areas while reducing false positives.
