Autonomous fire extinguishing system

Abstract

Fires are very dangerous and detrimental to life, property, and the environment. They spread rapidly and indiscriminately obliterate all things in their path. Fighting fires entails undeniable danger to life and the majority of suppression systems used to control them is at a broad-spectrum or macro scale. We present the design, fabrication, and testing of an autonomous fire extinguishing system. This system provides a unique solution to the problem of fires and their destruction by targeting the initial ignition of the fire and suppressing it before it starts to increase in intensity and range. The presented system detects, targets, and extinguishes a fire within a working space by using heat sensors, a flow control system, servo motors, and a water extinguishing gun. The system scans its workspace through motors and uses thermopile arrays to detect heat concentration gradients in its range. After the detection of the fire, the system then locks on to the target by extrapolating its location. Efficiency of the system, suppression accuracy, response time, power consumption, and work space area are also documented and presented in this paper. Future considerations and recommendations are highlighted to advance the system's design, efficiency, and scope. This is an indigenous solution to fire fighting in world and it is to make environment a healthier and safer place for the future.
