基于LabVIEW的脉搏检测系统设计

Based on LabVIEWMeasurement and Control Technology and Instrument,Measuring 2014 class Wei Cai LianSupervisor Gan Yong-jingAbstractThis topic to STC15 single-chip microcomputer as core control system of the heartrate meter design,by using infrared tube to pulse signal,the amplification filter circuit forfilter and amplification processing,the pulse signals using LM328 as op-amp designcontrol circuit to realize the collection of signal processing,the processing of signal intothe MCU A/D sampling and processing algorithm,the final realization of pulse waveformon the LCD panel and pulse frequency display.In addition,LabVIEW is used to design theupper machine to communicate with MCU.The measurement of human pulse and thereal-time monitoring of pulse waveform are realized.The design measuring pulse ratemethod is simple,the test result is accurate,the display interface is friendly,has therelatively good development prospect.Keywords:Pulse detection system,STC15W408AS,infrared emission receivingsensor,serial port,LabVIEW
