摘要

为实现谐振式光学陀螺中现场可编程门阵列(FPGA)主控芯片与上位机之间的数据传输需求,便于实时调整陀螺的各项参数、优化陀螺的工作状态。该文采用全双工通信RS422串口与USB接口实现了基于FPGA的谐振式光学陀螺数字检测系统与MATLAB上位机的连接。在分析了陀螺的工作原理的基础上,重点开展了RS422串口在陀螺系统中的软硬件和上位机通信功能设计。实验结果表明,该数据传输系统工作稳定,灵活可靠,能较好地实现谐振式光学陀螺与MATLAB上位机间的数据传输。
        In order to realize the data transmission between the FPGA master control chip and the host computer in the resonant optical gyro,and be convenient for the real-time adjustment of various parameters of the gyro and optimize the working state of the gyro,the full-duplex communication RS422 serial port and USB interface are used to realize the connection between the digital detection system of the FPGA-based resonant optical gyroscope and MATLAB host computer.Based on the analysis of the working principle of the gyro,the software and hardware of the RS422 serial port in the gyro system and the communication function design of the host computer are emphasized.The experimental results show that the data transmission system is stable,flexible and reliable,and can realize the data transmission between the resonant optical gyroscope and the MATLAB host computer.
