Design of Missile Borne Data Recovery System Based on Accelerometer

According to the requirements of real-time high precision and high speed acquisition for the multi channel signals in projectile penetrating, a kind of missile-borne recovery system based on MEMS acceleration sensor was designed in this paper. This system used FPGA chip XC3S400 as the main control unit of the circuit. The analog to digital conversion was realized by controlling the A/D converter( AD7934 ), and the collected data was cached by the FIFO and uploaded to the PC for display and analysis through USB3.0 interface chip CYUSB3014. The experimental result showed that the missile-borne recovery system had the features of rapid and accurate data transmission, no wrong frame and lost frame, and it can satisfy the need of the actual project. The proposed system has been successfully applied to the projectile penetration test with small size, low power consumption and high reliability.
