基于FPGA的MIMU信号处理技术研究

摘要

In order to use low-cost MEMS inertial measurement unit used in existing applications or test system,the signal conversion technology of MIMU based on FPGA is designed in this paper.The system can capture RS422 digital signal that MIMU output,and convert it to impulse signal that the fiber optic gyroscope output.The application show that this system is able to achieve the desired functionality,and achieve the design requirement.%为了实现低成本的MEMS惯性测量组合应用于现有应用系统或测试系统,提出了一种基于FPGA的MIMU信号处理技术方案,并完成系统的软硬件设计.该系统实现了采集现有MIMU输出的RS422数字信号,将其转换为目前激光或光纤陀螺的脉冲调制频率信号,使之能够应用于现有应用系统或测试系统.实际应用表面,该系统能够实现预期功能,达到了设计要求.
