摘要
文中介绍采用微波作为传媒并结合单片机的控制处理完成心律测量的“微波心律测量仪”的研制。这种心律测量仪的特点就在于它采用非接触方式来测量心律,利用微波的散射效应,通过检测经过人体散射以后的被心动信号调制了的散射波从而获得心动信号,进而得到所需的心律。
In this paper,the working principle,structure,circuit and software of “Microwave HBR Meter”is introduced.This kind of HBR Meter can be used in the case where non-connected manner is necessary for getting heart beat rhythm information.It gets HBR information by detecting scattering wave modulated by heart beat signal.
