【摘要】 针对目前大多数多生理参数监测产品存在的体积大、价格高的弊端,将智能手机与人体生理参数监测相结合,基于Android平台设计了一种多生理参数监测系统。系统采用集成芯片ADS1292R实现心电和呼吸信号的采集与模/数转换,采用AFE4400实现血氧信号的采集和模/数转换,完成了多生理参数监测系统的硬件和软件设计。设计的系统可实现3个主要功能:信号采集;将信号通过蓝牙模块发送到手机终端;在手机终端实现心电、脉搏波波形的绘制以及心率、呼吸、血氧和脉搏值的实时显示。更多还原

【Abstract】 Aiming at shortcomings of large volume,high price of most multi-physiological parameters monitoring products,combine intelligent mobile phone with human physiological parameters monitoring,a multi-physiological parameters monitoring system based on Android platform is designed. The system uses an integrated chip ADS1292 R to realize the acquisition of electrocardiogram( ECG) and respiratory signal and analog-to-digital conversion( ADC),and uses AFE4400 to realize the acquisition of blood oxygen signal and analog-to-digital conversion. The hardware and software designs of multi-physiological parameters monitoring system are completed.The system can realize three main functions: the acquisition of signals; transmit signals by Bluetooth module to mobile phone terminal; realize waveform drawing of ECG and pulse wave and the real-time display of heart rate,respiration,blood oxygen and pulse value.更多还原
