Penetration layer counting method based on stress-magnetic effect of projectile body

The invention belongs to the technical field of intelligent fuses, and provides a penetration layer counting method based on a stress-magnetic effect of a projectile body. The method is characterized in that a detonation control system is arranged in a penetration projectile body and comprises a magnetic sensor, a power supply module, an adaptive circuit module and a processing identifier circuit module, wherein when the penetration projectile body made of a ferromagnetic material penetrates through each layer of hard target plate, under the action of impact resistance, the stress-magnetic effect is generated, the magnetic field intensity of a magnetic leakage field on the surface of the penetration projectile body is changed, a magnetic signal serves as a layer penetrating signal, the generated magnetic signal is detected through the magnetic sensor, and an actually-detected sinusoidal impulse type analog voltage signal is preprocessed, subjected to analog-to-digital conversion and then sent to the processin
