基于FPGA的弹载数模混合采集存储系统设计

针对弹载试验过程中传感器输出方式的不同，设计了一种基于FPGA的弹载数模混合采集存储系统。系统选用Spartan-II系列的XC2S100作为核心处理器，采用16 bit的高精度A/D转换芯片ADS8365实现模数转换。FPGA控制将传感器输出的数字量和模拟量采集编码后存储到固态存储器FLASH中，最后，为了模拟系统在飞行过程中的状态，将系统放置在三轴位置速率摇摆温控转台上进行验证，试验结果证明，所设计的数模混合采集存储系统正确可靠，具有一定的工程应用价值。

Design of the Missile-borne Analog Digital Hybird Data Acquisition and Storage System Based on FPGA

Considering the different methods of sensor output in the process of the missile test,we designed a missile data acquisition and storage system that collected mixed digital and analog signal based on FPGA. The system select?ed the Spartan-II series XC2S100 as the core processor and used 16-bit high precision A/D conversion chip ADS8365 to convert analog to digital. FPGA control the sensor output of digital and analog acquisition encoded to the solid-state FLASH memory. Finally,in order to simulate the state of the system in process of flight,we placed the sys?tem on the three axis position rate temperature control turntable for validation,it was verified that the design of the module of mixed collection storage system was accurate and reliable and has certain engineering application value.
