基于 LabVIEW 的脉搏检测系统设计摘要本心率测量仪在设计中以 STC15 单片机作为控制系统核心，先采用红外对管采集脉搏的信号，然后将 LM328 作为运放设计调理电路对所采集的信号进行处理，完成处理之后，将其送至单片机实施 A/D 采样与算法处理，其后在液晶屏上显示出脉率与脉搏波形。此外，采用 LabVIEW 进行上位机的设计从而实现与 MCU 通信。基本实现了对人体脉搏的测量，以及对脉搏波形的实时监控。此次脉率测量的设计方式较为简捷，并且具有精准的测试结果与整齐大方的显示界面，因此其发展前景是光明的。关键词：脉搏检测系统，STC15W408AS，红外光电传感器，串口，LabVIEWDesign of pulse rate detection systemBased on LabVIEWAbstractThis topic to STC15 single-chip microcomputer as core control system of the heart rate meter design, by using infrared tube to pulse signal, the amplification filter circuit for filter and amplification processing, the pulse signals using LM328 as op-amp design control circuit to realize the collection of signal processing, the processing of signal into the MCU A/D sampling and processing algorithm, the final realization of pulse waveform on the LCD panel and pulse frequency display.
