摘要
脉搏波的波形特征与心血管疾病密切相关,为此用户需要一种简单、实时的便携装置。通过安装在正常使用鼠标时大拇指触摸到的鼠标位置的反射式脉搏波光电传感器采集脉搏波信号,信号经过滤波、放大和A/D转换后,利用单片机对脉搏波信号处理并得出心率数据,最后通过USB接口连接电脑端软件显示。将鼠标和反射式光电传感器结合制成成品之后,经过实际测试,传感器能够很好的测得手指脉搏波并输出。这种可监测人体脉搏波及心率的健康鼠标可以在用户使用鼠标的不经意状态时检测并记录脉搏波及心率。
Cardiovascular disease is closely linked to pulse waveform,so a simple and real-time portable pulse waveform detecting device is necessary for users.To collect PPG signals,a reflective PPG sensor is placed on the mouse where the thumb touching during mouse using.,Through filtering,enlarging and A / D converting the pulse signal,it was transformed into SCM and computed heart rate,and then data was transferred into computer to display by USB connector.The mouse and reflective PPG sensor were combined into finished products,the sensor measured the PPG signals well and outputted after the actual test.The healthy mouse monitoring PPG and heart rate can affect the user inadvertently using the mouse to detect and record the pulse and heart rate.
