摘　　要：为了提高分光光度计的智能化水平,开发了一种基于S3C2410嵌入式系统的可见光分光光度计。该系统以基于ARM9微处理器的S3C2410为核心,在其上移植了嵌入式Linux操作系统,开发了Linux下信号采集模块驱动程序和数据分析处理算法。利用MiniGUI进行软件界面的开发。实际应用表明:该系统能够实现光电信号的采集处理,透光率、吸光度、浓度等的自动计算,以及多种光谱图、标准曲线的绘制。系统界面友好、操作简单、功能较强、准确度高。This paper introduced the design of visible spectrophotometer based on ARM embedded system.The system was based on the S3C2410 micro-controller and the minimum Linux RTOS was transplanted.The data acquisition device driver and data processing algorithm was developed under Linux.The software interface was developed by using MiniGUI.The practical application shows that the system can achieve the signal real-time collection,the automatic calculating of the transmittance of light,absorbance,concentration,and the draw of standard curve.To apply the embedded system in visible spectrophotometer makes the operation easy,improves the veracity of calculation,and the system hsa a friendly interface.
