摘要
生物脉搏可在一定程度上反映心脑血管疾病的先兆信息,该信息的精确程度直接影响临床病情诊断的准确性.文章设计了一款以AT89C51单片机为核心的智能生物脉搏检测系统,采用ST188红外光电传感器获取生物脉搏信号,经过放大和整形等处理后,由单片机对脉搏信号进行定时累加计算,获得生物脉搏跳动次数,并通过LCD1602液晶屏显示测量结果.仿真及测试结果表明,与传统的脉搏检测方法相比,该系统使用便捷,具有较高的准确性.
Abstract
Biological pulse can reflect the precursor information of cardiovascular and cerebrovascular diseases to a certain extent,and the accuracy of the information directly affects the accuracy of clinical diagnosis.An intelligent biological pulse detection system with MCU AT89C51 as the core is designed.The biological pulse signal is obtained by using ST1 88 infrared photoelectric sensor.After amplification and shaping,the pulse signal is regularly accumulated by the single chip microcomputer to obtain the number of biological pulse beats,and the measurement results are displayed by LCD1602.The simulation and test results show that compared with the traditional pulse detection method,the system is convenient to use and has high accuracy.
