腕带式心率体温计设计
摘 要
在生活水平日益提升的前提下，人们对自身健康状况越来越关注。心率和体温是临床检查最常规的两个生理指标，通过它们可以简单初步的了解一个人的身体情况。本设计选用单片机STC89C52作为控制单元，选用反射式光电传感器SON1303采集心率信号,并用SON3130集成运放对其进行放大整形，输出心率脉冲信号，选用温度传感器DS18B20采集人体体温数据，将获取的心率和体温通过单片机实时显示至屏幕上，同时对这两个重要的人体机能指标进行分析，在不正常范围内利用蜂鸣器报警提示，从而构成一个基于单片机的腕带式心率体温计。

Abstract
Under the premise of rising living standards, people are increasingly concerned about their own health. Heart rate and body temperature is the most conventional clinical examination of two physiological parameters, they can by simple preliminary understanding of a person's physical condition. The design uses SCM STC89C52 as the control unit, use reflective photoelectric sensors SON1303 collect heart rate signal, and put them to enlarge reshaping SON3130 integrated operational output heart rate pulse signal, the selection of the temperature sensor DS18B20 collecting body temperature data, heart rate and body temperature will be acquired through the microcontroller to display on the screen in real time, while these two important indicators to analyze body functions, using a buzzer alarm is not within the normal range, so as to constitute a microcontroller-based heart rate strap thermometer.
