Abstract

Abstract:

In view of the current problem that active rifles can’t grasp the remaining amount of ammunition inside the magazine intuitively and accurately, a kind of equipment was designed to detect the number of remaining bullets in the magazine with MSP430F149 microcontroller as the core. According to the electrical signals generated by the displacement change of the spring which was caused by the increase or decrease of bullets in the magazine to MSP430F microcontroller, the microcontroller processed the signals and transmitted it to the monitor displaying in real time. Tests showed that the device was of high detection precision, convenient operation, and lower production costs without affecting the normal function of firearms.
