Design and Research of Intelligent Jet Fire Extinguishing System Based on STM32 and Image Recognition Technology

摘要

At present, the most widely used large-space automatic jet fire extinguishing system-LRB-automatic fire water cannon) is easily disturbed by sunlight in outdoor environment, resulting in accidental spray or unable to find the fire source. To address these issues, the proposed system integrates ultraviolet (UV) sensors and image recognition technology to accurately detect and extinguish flames, both indoors and outdoors, at a lower cost. The system is divided into multiple modules, including image processing, main control, mobile robot base, and power management. The camera filters visible light interference using a narrow-band filter, while the UV sensor detects open flames, enabling accurate tracking. The water cannon is mounted on a mobile robot, which can autonomously adjust its position to enhance fire-fighting efficiency. The paper highlights the modular design, allowing for easy upgrades without affecting other components. Additionally, the system can be expanded to include automatic patrol capabilities and remote monitoring for broader fire coverage in large spaces.
