基于数字化动物体脉搏计电路设计实现研究

Study on the Circuit Design and Implementation on the Basis of the Digital Animal Sphygmometer

通过设计由压电传感器采集非电量生物信号,经过放大、整形后,输入单片机内进行相应的控制,从而测量出1min内的动物体脉搏跳动次数,并以数字显示的脉搏计,测量的脉搏数范围40-200次/min,适用于各种哺乳动物机体。通过观测脉搏信号,检查动物体的健康状况,能够判断心率不齐且进行告警显示。

The sphygmometer was designed by piezoelectric sensors to collect the non-electric biological signals which can be amplified and shaped,then the treated signals are input to the single-chip microcomputer with corresponding control.Furthermore,people can measure pulse beat frequency of animals in a minute,and the frequency can be showed by numbers.This digital animal sphygmometer can measure pulse beat at 40 - 200times/min,which can be suitable for all kinds of mammals.Through observing the pulse signals and checking the status of animals＇ health,people can determine whether animals are arhythmia and send warnings.
