【摘要】In order to achieve the low-cost, high speed and high precision fiber grating sensing demodulation, the paper designs a fiber grating sensor demodulation system based on FPGA. The system includes the data collection and A/D module, the FIR digital filter module, the data cache module based on SRAM and the display module. The system provides a global system syn-chronization clock by the FPGA control module for each sub module. Compared with the conventional fiber Bragg grating sensor demodulation device based on FPGA, the required components of design are in the same piece of FPGA development board. It not only reduces costs but also improves the tone of the instrument system integration. By system experimental verification, the fiber grating sensor demodulation system based on FPGA is successful. Last, an application is proposed about the system, it shows the system has certain practical significance.%设计一款FPGA的光纤光栅传感解调设备,实现光纤光栅传感的低成本高速解调。该光纤光栅传感解调设备由数据采集和A/D模块、FIR数字滤波模块、数据缓存模块和显示模块4大核心模块组成。系统由FPGA主控模块为各个子模块提供全局系统同步时钟。与现有的基于FPGA的光纤光栅传感解调仪相比,设计所需元件均嵌在同一块FPGA开发
