脉搏血氧检测仪软件设计优化

摘要

The design of software for pulsoximeter based on MSP430FG4618 single chip micro-controller bluetooth communication is introduced,which can be used for measurement in both pulse of heart and oxygen saturation in blood.On the foundation of theory of the solution,software modules runing on the microcontroller such as sample and computation,algorithm of ⅡR for low pass dc-track filter,algorithm optimization of FIR for low pass filter,computation of oxygen saturation of blood and pulse of heart,and self-conduct of dc-voltage.In addition,bluetooth software module used for data communication is also gaven out.%为了实现基于蓝牙的脉搏血氧仪的设计,给出了基于MSP430FG4618单片机为核心控制器的脉搏血氧监测仪解决方案的整体设计.在阐述解决方案原理的基础之上结合单片机的具体特征,提出了软件方案的设计实现和优化,如数据采样的中断、无限长脉冲响应低通滤波器的算法优化设计、有限长脉冲响应低通滤波器的优化设计、计算血氧饱和度和脉搏的设计方案、直流电压的自我调节以及蓝牙通信的软件设计.
