摘要
采用MSP430超低功耗单片机实现对光电容积脉搏波的检测,并根据反射式测量原理设计了光电容积脉搏波的反射式检测探头。由MSP430单片机控制LED的发光、数据的采集以及Zigbee无线通信模块的收发功能,并采用数字信号处理技术去除噪声干扰。实验表明,所设计的光电容积脉搏波检测模块能准确地实现脉搏波信号的检测、数据传输及脉率输出。该模块适合在日常环境下容积脉搏波的实时监测。
The reflective photoplethysmography（PPG） detection module is realized by the ultra-low power consume MSP430 processor.For this module,the wireless data transmission is realized by the Zigbee module and noise is removed by filtering signal processing.Experiments show that the designed module can detect photoplethysmography correctly and data can be transmitted wirelessly in real-time,and pulse rate can also be obtained accurately.The wireless PPG detection module is applicable in everyday environment.
