摘要

人体的血氧信息和脉搏信号是衡量人体健康状况的两个重要参数，是维持人体生命活动的重要前提。因此不管是在突发的紧急情况还是医疗领域甚至运动保健等生活中的常见场景下，对血氧和脉搏信号的测量和监测都显得至关重要。

本设计以51单片机为核心，主要包括光电传感器采集模块，数模转换器模块，LED显示模块和蓝牙模块以及手机端。单片机是一种集成多种功能的微控制器，在我们日常生活中的各个领域的应用都相当普遍。指套式光电式传感器的物理基础是光电效应，精度高、反应快且非接触，能在各种光电检测系统中实现光电转化。由发光二极管和光敏二极管组成，能够有效采集人体信号，为人体的血氧和脉搏信息的提取和分析提供良好的数据来源。

通过单片机结合光带传感器测量人体的血氧和脉搏数据，并且能够实现在手机端的实时监测，这一设计将会对患有血管或呼吸系统疾病的病人、60岁以上的老年人、进行极限运动长期酗酒等人群带来福音，及早发现危险，减少意外发生。

Abstract

The blood oxygen information and pulse signal of human body are two important parameters to measure the health status of human beings, and they are the important premise to maintain the human life. Therefore, the measurement and monitoring of blood oxygen and pulse signals are very important, whether in emergency situations or in the medical field, or even in the common situations of sports, health care and so on.

The design of the 51 single-chip microcomputer as the core, including photoelectric sensor acquisition module, digital to analog converter module, LED display module and Bluetooth module, as well as mobile terminals. SCM is a micro controller integrated with various functions. It is widely used in every field of our daily life. The physical basis of the fingertip photoelectric sensor is the photoelectric effect, high precision, fast response and non-contact, can realize photoelectric conversion in photoelectric detection system. It is composed of light emitting diode and photosensitive diode, which can effectively collect human signals, and provide a good data source for the extraction and analysis of human blood oxygen and pulse information.

With the band sensor measuring the body's oxygen saturation and pulse data through the microcontroller, and can achieve real-time monitoring in the mobile phone terminal, the design will have vascular or respiratory disease patients, 60 years of age or older, extreme sports long-term drinking crowd to bring the gospel, early detection of risk, reduce accidents.
