文档介绍：摘要脉搏传感器采样脉搏信号,采用 STC89C51 单片机作为控制器,脉搏传感器输出方波传入单片机,单片机每接收一个脉冲波形,数码管就计数一次。脉搏次数超限时用蜂鸣器报警。三极管加大功率,驱动器件工作。单片机软件设计, 设置中断向量, 编程执行。关键词:STC89C51 单片机、脉搏测量仪、软件设计 A bstract : Pulse sensor sampling pulse signal, using STC89C51 MCU as controller, pulse sensor output square wave into single chip puter chip, each receiving a pulse waveform, digital tube counting time.
