基于MSP430G2452单片机的便携式脉搏测试仪设计

摘要

人体脉搏测试仪在我们日常生活中已经得到了非常广泛的应用。设计一种基于MSP430G2452单片机的脉搏测试仪。系统采用了红外发射与接收二极管充当脉搏传感器来采集脉搏信号，通过信号调理与放大后，送至单片机处理，在LCD屏中显示出脉搏跳动波形，并设有脉搏次数上下门限报警功能。通过试验表明，该系统各项技术指标达到了设计要求，并能有效地抑制干扰提高精度，具有低功耗低成本的特点。%This paper designs a puIse tester based on MSP430G2452 microcontroI er.In the system it uses the infrared transmit-ting and receiving diode and acts as puIse sensor to coI ect the puIse signaI.The signaI is processed and ampIified and sent to the microcomputer processing,LCD wiI dispIay the puIse waveform.It is equipped with puIse frequency fIuctuation threshoId aIarm function.The test resuIt shows that aI the indicators can meet the design requirements.
