摘　　要：为了满足光谱仪的小型化、智能化的要求,提出了基于Linux操作系统的光谱仪数据采集系统的设计方案,可以方便后续应用研究软件的开发;该方案主要采用Intel公司的PXA270作为光谱仪的处理器,SONY公司的ILX554B高灵敏度线阵CCD作为光电探测器,设计了光谱仪的硬件采集电路,并在分析Linux设备驱动的基础上,针对光谱仪的硬件采集电路,设计了Linux操作系统下采集设备的驱动程序,实现了光谱仪的光谱数据采集功能;经过测试,该驱动能够满足Linux操作系统下应用程序的需求。In order to meet the need of miniaturization and intelligence, this paper provide a blue print for data collection system for spectrometer based on Linux system. This spectrometer is mainly based on XScale processor designed by Intel company and CCD ILX554B designed by SONY company. Based on the analysis of the design methods of device driver under Linux system and considering of hardware of collection system for spectrometer, device driver for collection based on Linux system is designed, and the collection function is implemented. After testing, the driver can meet the application＇s demand is in the Linux operating system.
