The Signal Processing and Time-Sequence Controlling Based on FPGA in FOG

在光纤陀螺数据处理系统中,干涉信号数据转换处理及其时序控制是非常关键的,它们是系统设计的核心。以FPGA为技术背景,针对光纤陀螺原理和干涉信号的特点以及高速A/D转换器件性能与工作特点,采用VHDL语言设计A/D采样控制电路,精确实现光纤陀螺高速数据的采样与转换。实际工程应用表明,系统工作可靠,结构合理,具有很高的实用价值。

The date pocessing and time-sequence controlling of interference signals are very crucial in FOG's date processing system, they are the heart in the system design. According to FOG's principle interference signals' characters and A/D converter's performance, the design in this article realizes the sampling and conversation of FOG's high-speed data precisely by using VHDL. Practice shows that the design system has great practical value with reliable performance and reasonable structure.
