摘要当代社会，随着生活水平的提高，人们对于自己的身体更为重视，商业化的个人健康检测仪因此也越来越普及了。它已经从医院走到了我们的生活中来。本次设计的是一种基于51单片机的个人健康检测仪。它主要有2个功能，测量人体体温和脉搏跳动次数。它们都是以STC89C52芯片为核心，然后分别通过温度传感器和光电传感器来实现对体温和脉搏的测量，再通过液晶显示屏把各项数值显示出来。此次设计中，我还加入了一个关于脉搏的警报装置和一个实时观测脉搏跳动并通过小灯闪烁来显示的装置。68853

本此设计，我还添加了一个有趣的功能，即定时功能。其意义在于它可以及时提醒你使用个人健康检测仪来进行检测。它与脉搏报警装置一样通过蜂鸣器发出声音来提示你。并且，何时需要测量这也是可以自己进行设定的。它可以通过时钟模块和按键来实现。

本设计有图12张，表1张，参考文献18篇。

Design of Personal Health Detector Based on Single Chip

Abstract

In contemporary society, with the improvement of living standards, people pay more and more attention to their health. Industrial detector production for personal health becomes more and more popular. It has came to our lives from the hospital . This design is a based on 51 MCU personal health detection instrument. It has two functions, measurement of body temperature and pulse frequency. They are based on STC89C52 chip as the core respectively, then the author temperature sensor and photoelectric sensor to realize the measurement of body temperature and pulse, and through the LCD display to the values shown. I also joined a pulse the alarm device and a real-time observation of the pulse and by means of small light flashes to display in this design.

This design also add an interesting feature, the timing function. Its significance lies in that it can timely remind you of the use of personal health detection instrument to detect. The pulse of the alarm device as through the buzzer sound to prompt you. And, no matter when you measure this also can set themselves. It can be realized through the clock module and the key.

     This design has 12 figures, 1 tables, 18 references.
