基于 LabVIEW 的脉搏检测系统设计 摘要本课题以 STC15 单片机作为控制系统核心的心率测量仪的设计，以红外光电传感器作为检测人体心率脉搏的元件，采集到的心率脉搏信号再传送到单片机电路进行处理，得出的数据在 LCD12864 显示出来。当系统运行时，LCD12864 显示是当前人体的脉搏心率跳动次数、脉搏波形，测量结束后显示的是最后一次测量脉搏心率跳动次数和脉搏波形。再通过单片机采集脉搏信号，利用功能强大的虚拟仪器LabVIEW 设计出脉搏的采集与分析系统。在单片机上实现了采集脉搏传感器的模拟信号，然后通过串口将数据传输到上位机进行处理与分析，实现远程监控的功能。实验结果表明，系统工作正常，测量灵敏度高，实现了设计功能。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 LabVIEW Abstract This topic for this STC15 single-chip microcomputer as a control system for the core of the heart rate meter design, with infrared receiving sensor as the detecting element of human pulse of heart rate, heart rate were collected pulse signal transmit to MCU circuit for processing, the data in LCD12864 display. When the system is running, the LCD12864 display is the current pulse rate of the pulse rate of the human body and the pulse waveform. After the measurement, the pulse rate of the pulse rate and pulse pulse are measured. By single-chip microcomputer to collect the pulse signal, the use of powerful LabVIEW virtual instrument design pulse acquisition and analysis system, on the single chip microcomputer to realize the collection of the analog signal of the pulse sensor and then through a serial port to transmit data to PC for processing and analysis, realizes the remote monitoring function. The experimental results show that the system works normally, the measurement sensitivity is high, and the design function is realized.Keywords:Pulse detection system, STC15W408AS,i...
