when the cannonball 2 passes through an ignition point, the infrared imaging sensor 4 receives a heat source signal, and then the electromagnetic valve 42 in the opposite direction is controlled to be opened, so that compressed air in the air storage chamber 23 is sprayed out through the guide hole 41, the cannonball 2 is further steered and hits the ignition point, and the accurate fire extinguishing efficiency of the cannonball 2 is improved; the stop lever 47 extends into the air storage chamber 23 in an initial state and abuts against the piston 25, so that the phenomenon that the thimble 26 slides and is falsely triggered due to vibration in the transportation process of the shell 2 is avoided, the slide ring 45 of the shell 2 slides towards the direction close to the tail part of the shell 2 due to inertia during launching, then the contact pin 5 pushes the sealing gasket 49 open, the compressed air in the rear slide hole 46 is discharged, the stop lever 47 resets under the action of the tension spring and releases the limitation on the piston 25, and the normal operation of the piston 25 is further ensured; the fin 51 and the slide rod 52 are pressed when the slide ring 45 slides, so that the slide rod 52 is inserted into the cylinder 27, and the stirring effect of the slide rod 52 on the mixture in the cylinder 27 is further increased; the gear 55 is driven to rotate by the servo motor, so that the rack 54 and the electromagnet 53 are driven to slide, the shell 2 is adsorbed by the electromagnet 53, the position of the shell 2 in the gun tube 13 is adjusted, the emission speed of the shell 2 is accurately controlled under the condition that quantitative compressed air is filled into the air inlet hole 15, and the fire extinguishing efficiency of the shell 2 is improved; when compressed air is filled into the gun barrel 13 through the air inlet hole 15, part of the compressed air is filled into the air cylinder 56 through the overflow hole, the driving gear 55 is further separated from the rack 54, meanwhile, the pressure spring 58 ejects the rack 54, so that the electromagnet 53 slides along with the shell 2 for a certain distance, and meanwhile, the abrasion between the shell 2 and the inner wall of the gun barrel 13 is reduced through the repulsion effect of the electromagnet 53 on the magnetic ring 44, and the efficiency of propelling the shell 2 by the compressed air is further increased.
