1、 摘 要 随着社会的飞速发展，人们的生活方式和膳食结构发生了巨大的变化，与此 同时，人类因各类突发性疾病的死亡率逐年提高，心血管疾病已成为威胁人类健 康的多发病，而且发病率逐年提高，发病年龄也出现下降趋势。心脏病是人们难 以预防的突发性疾病，所以自身的健康也被越来越多的人所重视。本设计要解决 的就是可以测量心率，预防心脏病等心血管方面的疾病的心跳监控系统。 本设计采用以 AT89S52 单片机为核心控制器件的低成本、高精度、体积小的 数字显示的心率计。心率监控系统的工作原理是利用 SC0073 型压电传感器接收 到人体信号，通过电路中的放大电路将信号放大、整形处理，最后再传给单片机 AT89S

2、52 处理，处理完成后由三位数码管显示出来。整个监控系统采用模块化设 计，由主程序、预置子程序、信号采集子程序、信号放大处理子程序、显示子程 序等模块组成。 传感器探头采集的信号经单片机分析处理， 实现心率测量的功能。 在此基础上设计了心跳监控系统的总体方案， 通过硬件和软件来实现各个功能模 块。 该心跳监控系统可以便捷的测量出人体的心跳，基本实现预定的目标，大大 降低测量心跳的时间，且方便携带。 关键词：关键词：AT89S52；SC0073；心率；监控系统 Abstract With the rapid social development, peoples lifestyle and di
