摘要
基于脉搏检测原理,以STC89C52单片机为硬件处理核心,采用红外对管传感器,利用单片机内部的定时器来计算时间,经过单片机定时累加得到脉搏数据,检测数据由液晶显示同时进行语音播报。系统的软件程序由C语言编写。
Through the research of pulse detection principle, using STC89C52 microcontroller as the core hardware, using infrared tube sensor to measure time using MCU internal timer, after timing was obtained by adding pulse data, test data from the liquid crystal display and voice broadcast. The software program of the system is written by C language.
