High-rise building firefighting method and system

The invention discloses a high-rise building firefighting method and system. The high-rise building firefighting system comprises a firefighting truck, a fire hose, connection bushes, connection components, unmanned gyroplanes, fixed bases, firefighting nozzles and a control system, and is characterized in that two ends of the fire hose are separately connected with the firefighting truck and thefirefighting nozzles; the unmanned gyroplanes are connected with firefighting water hose through the connection components and the connection bushes; long-time hovering of the unmanned gyroplanes is ensured through electric wires; control signals of the unmanned gyroplanes are not affected by ambient magnetic fields through data cables; and the control system controls the firefighting nozzles to finish firefighting work in high-rise buildings by controlling positions of the unmanned gyroplanes. By adopting the high-rise building firefighting method and system, through effective combination ofthe multiple unmanned gyro
