摘　　要：设计了一种基于嵌入式Linux和ARM的可见分光光度计。该系统以ARM处理器为控制核心,采用均值法和比例式处理检测数据,数字显示透射比和吸光度,自动计算溶液浓度和绘制光谱图。实验表明:系统不仅操作简单,功能齐全,且能准确检测溶液的透射比和浓度。A visible spectrophotometer based on embedded linux and ARM is designed. The system uses the ARM processor as its control core, adopts average method and proportion formula to handle the testing data. It can digitally display transmittance and absorbance, automatically calculate solution concentration and draw spectrogram. The result of experiment shows that the system not only has the advantage of easy operating and complete functions, but also can inspect transmittance and concentration accurately.
