| 摘 要： | 快速心率检测仪是通过由红外线发光二极管和光敏三极管组成的反射型红外光电传感器采集指动脉搏动波信号 ,经过放大和整形处理 ,送入单片机进行计算 ,快速地转换为一分钟心率 ,并将结果予以显示。该仪器能快速检测并显示被测者的心率 ,完成一次测量仅需2～3秒钟。本文详细介绍了快速心率检测仪的设计思路。

| Abstract: | The fast photoelectricitical instrument for examing heartbeat (FPIEH) is able to collect the wave signal of a finger artery by a reflecting infrared photoelectricitical sensor made up of LED and photoelectric dynatron, and then to magnify and plasticize the signal. We send the final signal to single chip micyoco(SCM), the SCM will change the signal to a rate of per minute and the result is showed. FPIEH can exam and show the heartbeat rate of a tester in a very short time. This article introduce the idea of FPIEH in detail. |
