基于FPGA的国产MSA009加速度计测试系统设计

Design of Testing System for Domestic MEMS Accelerometer MSA009 Based on FPGA

针对国产MEMS加速度计MSA009的工作原理和输出特性,设计了一种测试系统,以SpartanⅡ系列的XC2S30为主控芯片,并结合外围电路搭建了测试系统;基于ISE 8.1平台,采用VHDL硬件描述语言实现了对A/D转换芯片和Flash的控制,完成了加速度计输出信号的实时采集与存储;利用高精度三轴位置速率转台对测试系统进行试验验证,并对所采集的数据进行分析处理;经试验论证,该测试系统实现了对MSA009加速度计的测试,具有良好的实用性、稳定性。

In this dissertation, according to the principle and the output property of the domestic MEMS accelerometer MSA009, a measurement system is designed, which used Xilinx company＇s XC2S30 as the main control chip combine with peripheral circuit. On the basis of ISE 8. I development tool, the design realized the control of the A/D chip and Flash and completed collection and storage of the output sig- nal of accelerometer. The measurement system is experimentally demonstrated by use of high precision three axis position turntable and the collected data were analyzed. As is shown in the test, the measurement system achieves the test of MSA009 accelerometer and has the guid- ing role in the late work.
