摘　　要：设计一款智能心率监测系统,主要应用于老年人和中年人的智能穿戴领域,其便携式的心率测量使用方便。采用反射式光电传感器作为前端信号采集,将得到的信号进行转换和数字滤波,经过心率计算后得到的数据无线传输给监控终端,可实现智能化和网络化的实时监测。当接收到的心率测量数据不在人体心率安全范围内时,系统会启动报警,可及时避免突发疾病因时间耽误急救。该系统设计经过多种运动状态试验对比,表明此设计的智能心率监测系统具有稳定性、高精度和可行性。An intelligent heart rate monitoring system is designed,which is mainly used in the intelligent wearable fields ofthe elderly and middle?aged people,and is convenient for portable measurement of heart rate.The reflective photoelectric sensoris used to acquire the front?end signal,then the transformation and digital filtering are performed for the received signal,andthe data calculated with heart rate monitoring system is transmitted to the monitoring terminal in the wireless form to realize theintelligent and networked real?time monitoring.If the measured heart rate data received by the signal acquisition module is out ofthe security scope of human heart rate,the system will start the alarm to timely prevent the delay before the first aid of paroxys?mal disease comes true.The experimental contrast was conducted for the system design with a variety of motion conditions.Theexperimental result shows that the intelligent heart rate monitoring system has high stability,high accuracy and strong feasibility.
