This article introduces the severe fire situation in China, and clarifies the limitations of the existing fire-fighting solutions. In view of the limited range and the limitation of the use of pyrotechnics, it is proposed to use the electromagnetic coil launcher to launch the fire-extinguishing bomb to extinguish fire. Based on the current filament circuit model, a 10-stage electromagnetic coil launcher is designed. Pulse capacitor is used as the initial energy source and the coil is discharged sequentially by a crowbar circuit. The 7.2 kg projectile could be accelerated to the maximum speed of 171 m/s and the muzzle speed of 154 m/s. The efficiency will be over 15%. It shows that the electromagnetic coil launcher can meet the launching needs of fire-fighting project's needs. An intelligent unmanned electromagnetic launch fire-fighting system is proposed. The intelligent command and control system dispatches drones to collect fire information, then formulates fire-fighting strategies. The unmanned electromagnetic fire-extinguishing vehicle will be controlled to launch fire-extinguishing bombs to achieve accurate and efficient fire extinguishing. The system will adjust the fire extinguishing plan according to the evaluation results of fire extinguishing efficiency until the task is completed.
