Abstract:  By analyzing the current situation of high- rise building fire-fighting equipment , the shortcomings were pointed out and a new type of fire-fighting equipment that uses electromagnetic force to launch fire- fighting bombs was proposed and designed. The principle of fire extinguishing bomb launching, the overall composition of equipment and the working process were introduced. The electromagnetic force is simulated by ANSYS Electronics. The research and development of electromagnetic ejection system makes up for the deficiencies of existing firefighting equipment for high- rise buildings, and provides a new solution for rapid fire- fighting and rescue for high- rise buildings. 

Key words:  , fire fighting, fire cannon, electromagnetic ejection, high-rise building, fire-extinguishing shells
