基于MSP430的低功耗脉象信号采集系统

Low Power Pulse Signal Acquisition System Based on MSP430

脉象信号包含了许多生理病理信息,可以为医生诊断疾病提供重要依据。针对当前脉象仪功耗大、成本与仪器精度不可兼得等缺陷,设计了一种低功耗、微型化、可实时通讯的脉象信号采集系统。该系统采用HK-2000B脉象传感器进行采集,以MSP430单片机为核心,对信号进行分析、处理与结果显示,实现了脉象信号实时、连续的检测。通过多次实际测试,结果表明该系统可以适用于不同人群,能够准确显示脉象信号和相关参数,为医生对病情诊断提供有用信息。

Pulse signal contains many physiological and pathological information,an important basis to diagnose the disease for the doctors can be provided.Due to the defects of the pulse instrument such as power consumption and the balance between price and instrument accuracy,a kind of low power,miniaturization,real-time communication pulse signal acquisition system is presented in this paper.The system which used HK-2000 B pulse sensor to acquire the pulse signal,the MSP430 chip is taken as its CPU to process the collected signal and the results is displayed on the screen;the detection of pulse signal real-time continuous is realized.After repeating the experiment,the testing result shows this system can be applied to different groups of people;the pulse signal and the related parameters can be accurately displayed;the useful information to disease diagnosis for the doctor is provided.
