Design of analog electromagnetic launcher based on STM32

Abstract In order to improve the accuracy of the electromagnetic launching system, this paper designs a simulated electromagnetic launching device based on STM32 MCU, which takes the steering gear pylons as the motion system, the solenoid coil as the launching system, and the capacitor as the energy storage element. After collecting data, the microcontroller controls the deflection of the pylon steering gear to adjust the launching Angle or the control transformer to adjust the launching voltage, and then controls the charging or discharging of the capacitor to provide energy for the launching device to launch the projectile. Two modes, automatic and manual, are designed. The former takes OpenMV as the target identification and ranging device, and transmits data to SCM through serial communication. The latter can be displayed on the OLED screen by entering the target position through a manual key. The launcher simulates the real electromagnetic launcher and realizes the automatic and accurate launch of the projectile.
