Dhwani Fire: Aerial System for Extinguishing Fire

Abstract

Fire is among the most feared dangers. Therefore, a fire extinguisher is necessary equipment. Unfortunately, conventional fire extinguishers have certain disadvantages, such as the use of hazardous chemical ingredients that leave a residue. The current extinguishers use a variety of chemicals depending on the types of fires to be extinguished. They are usually pressurized with nitrogen or carbon dioxide and when this pressure is released on fire, they extinguish it. Water, potassium bicarbonate, foam, and other asphyxiating and extinguishing agents are commonly used materials in the current fire extinguishers. All of these agents leave behind some byproducts that are toxic and pollute the environment. The proposed firefighting system consists of an Unmanned Aerial Vehicle (UAV), a drone that has two sets of sensors, an image capturing unit, a sound wave generator, a cooling assembly, and a processing unit onboard. The first set of sensors is configured to detect heat parameters of the fire, while the second set of sensors detects one or more airborne particulates in the fire area. The image capturing unit navigates and captures images of the fire area. The sound wave generator and the cooling assembly are controlled by the processing unit configured to actuate them and enable the system to extinguish fire. The system usability test exhibits that this sound wave-based firefighting extinguisher is a novel, cleaner, safer, and user-friendly firefighting solution.
