Urban Buildings Fire Extinguishing System Based on Unmanned Aerial Vehicles is composed of Ground Transportation Command and control vehicle, small and medium-sized UAV and fire extinguishing bomb. It is suitable for fire extinguishing of high-rise buildings in cities.

        When the ground transportation command and control vehicle receives the emergency fire alarm, it quickly drives to the fire area. UAVs are deployed on the ground, equipped with photoelectric reconnaissance equipment and fire extinguishing bombs, and then UAVs take off. The image is transmitted to the control vehicle in real time. When the UAV arrives in the air about 20 meters from the window of the burning room, the aircraft hovers. Fire extinguishing bombs are fired at the fire-fighting room. Fire extinguishing bombs break windows and enter the fire-fighting room. After entering the room and landing stably for 5 seconds, the fire extinguishing bombs slowly releases ultra-fine dry powder from the top side nozzle of the extinguisher. The fire was extinguished rapidly under the continuous physical and chemical action of dry powder particles. When the fire is serious, several UAVs can take off to extinguish a fire together.

System characteristic

        ① The system has complete functions and is easy to use: The system uses medium and small UAVs, which can take off and land vertically. It is convenient to shuttle between high-rise buildings in cities and is not restricted by ground traffic. UAVs can hover near the window of the fire room for short range launching without high aiming accuracy.

       ②No hidden danger of personnel safety, small incidental loss: The fire extinguishing bombs use rocket engines, which have small recoil force and will not cause damage to UAV. At the same time, The fire extinguishing bomb does not explode when it enters the room, but quietly sprays dry powder, which will not cause secondary damage to the buildings and the unexplored persons or indoor objects in the room.

        ③ Low cost: Launcher and UAVs can be used repeatedly, greatly reducing the cost of fire extinguishing.
