摘 要

本设计的人体脉搏检测的系统是基于51单片机，从实用价值和性价比性能方面作为参考依据，本课程决定红外光电传感器人体脉搏检测装置的收集信号模块，体表温度的采集模块决定用18b20温度传感器，再外加LCD显示模块。人体的心率检测及体表温度采均使用指尖轻触的方式，采集的数据和信号经过单片机处理完善后再由LCD显示模块显示示数。最后通过手机WIFI连接上传到手机数据显示APP。

Human Pulse Sleep Detection Device Based on Single Chip Microcomputer

Abstract

This design of the human pulse detection system is based on 51 single-chip microcomputer, from the practical value and cost-effective performance as a reference basis, this course decided to infrared photoelectric sensor human pulse detection device signal collection module, body surface temperature collection module decided to use 18b20 temperature sensor, plus LCD display module. The heart rate and body surface temperature of the human body are measured by fingertip touch, and the collected data and signals are processed and improved by single chip microcomputer, and then displayed by LCD display module. Finally, the data is uploaded to the mobile phone data display APP through the mobile phone WIFI connection.

Keywords: 51 Single-chip Microcomputer；WIFI Module；Heart Rate；Body Temperature
