Description

System and method for extinguishing fires using drones The present invention relates to a fire extinguishing system and method using a drone, and more specifically, to a fire extinguishing system and method using a drone that enables rapid fire extinguishing using fire extinguishing equipment after rapidly moving a drone equipped with fire extinguishing equipment to a fire site. Traditionally, when a fire occurred, personnel near the point of origin would extinguish it directly using fire extinguishers, or fire trucks and other vehicles would be dispatched to put out the fire. However, there were frequent instances where small fires were left unattended and escalated into large-scale fires due to a lack of personnel near the point of origin, or because, even when personnel were present, firefighting equipment was unavailable or not properly utilized. Furthermore, even when fire trucks are dispatched, they frequently face difficulties and delays in reaching the fire site due to urban traffic conditions and other obstacles. In suburban areas, when fires occur due to the burning of farmland, it often takes a significant amount of time for fire trucks to arrive and extinguish the fire due to the absence of nearby fire stations. Recently, electric vehicle fires have emerged as a significant concern, while internal combustion engine vehicles also pose a fire risk due to high summer temperatures. Furthermore, small fires frequently occur during activities such as cooking while camping or burning on farmland; if not extinguished in the early stages, these fires pose a risk of escalating into large-scale blazes. However, traffic conditions and other obstacles have frequently hampered fire trucks from responding to fires. Many inventors recognize the importance of being able to quickly reach the source of a fire and prevent its spread into a large-scale fire and additional human and material damage, and are researching and developing solutions to address this, but satisfactory results have not yet been achieved.
