摘　　要：该文以STM32芯片为核心,设计了一套基于近红外光谱技术(Near-infrared Spectroscopy,NIRS),可用于临床的脑血氧数据采集与显示系统。首先介绍了脑血氧(Sa O2)检测的基本原理,阐述了系统方案,介绍由光源、光源驱动、光电检测及信号处理等模块组成的硬件系统,以及基于u C/OS-III的软件系统。最后通过前臂阻断实验和3D电视实验验证了本系统的可行性和有效性。本系统具有无创伤,体积小,数据存储,方便移动,使用便捷等特点。A system was designed in this paper, which can be used in clinical cerebral oxygen data acquisition and display, it is based on STM32 and NIRS(Near-infrared Spectroscopy). First of all, this paper introduced the basic principle of Sa O2 detection, and system scheme. Next, it illustrated the hardware system which is composed of the modules of LED, light source driver, photoelectric detection, and the signal processing. Then, the software system based on u C/OS-III of the system was presented. At last, the feasibility and effectiveness of the system were verified by forearm occlusion and 3-D TV experiment. This system is noninvasive, small-volume, mobile-convenient, easy to use and can storage data.
