摘　　要：傅里叶红外光谱仪高效、可靠地获得光谱数据对于后续定性和定量分析物质有着重大的意义。使用FPGA的并行处理能力和可自定义外设构建灵活的片内系统,配合外部硬件电路设计,提出了一种基于FPGA的可定制高效稳定地采集、存储和传输光谱数据的系统实现方法。阐述了基于FPGA完全使用硬件实现干涉信号采集和存储的方法,用以提高数据采集的可靠性。通过最终的实验结果表明,系统可以长时间稳定的运行,解决了使用ARM进行数据采集和传输出现数据丢失的问题。The efficient and reliable acquisition of spectral data by Fourier infrared spectrometer is significant for the subsequent qualitative and quantitative analysis of substances. Using the parallel processing capability of FPGA and the characteristic of building flexible in-chip system with customizable peripheral and combining with the design of external hardware circuit,a system implementation method based on FPGA can be customized and efficiently and stably collect,store and transmit spectral data was proposed. The method of interference signal acquisition and storage based on FPGA was described to improve data acquisition reliability. The final experimental results show that the system can run stably for a long time and solve data loss in ARM data acquisition and transmission.
