摘要
设计了一种纽扣式无线心率监测系统,该系统采用光电容积法(PPG)设计了一款纽扣式传感器实现对心率信号的采集和预处理,利用微处理器Atmega 328进行ADC和心率计算,通过蓝牙将处理后的数据上传给基于LabVIEW设计的心率监测软件,实现对心率信号长时间实时的监测。对5名受测人员分别使用心率监测系统和人工方法进行多次重复性心率测试,心率监测系统的误差小于2%。结果表明,该系统性能稳定,实现了语音提示、语音报警、数据库建立、海量数据存储等功能。
To improve the poor flexibility and functionality of the heart rate measurement systems, a button-type wireless heart rate monitoring system is presented. In this system, the button sensor is closely related to photo plethysmography （PPG） used to collect date about heart rate and pre-process the signals. Microcontroller chip Atmega 328 is used as a core to compute ADC and heart rate and transmit the data to LabVIEW via the bluetooth. Finally, the software of the heart rate monitor is responsible for real-time receiving and monitoring of heart rate signals for a long time. Five persons were selected to test the performance of the heart rate monitoring through repeatedly test by using heart rate monitoring system and artificial method, respectively. The error of heart rate monitoring system was less than 2%. The results show that the system is reliable and realizes the functions of voice prompt, voice alarm, database building, massive data storage. It also has the characteristics of small size, good flexibility, cheap cost, multiple functions, and can be used for long time monitoring and analysis for the users, which has good application prospects in daily life.
