摘要
随着人们健康意识的不断提高，对个人健康状态的实时监测与及时干预变得愈发重要。传统的健康监测方式往往依赖人工记录、定期体检，存在数据滞后、无法及时预警等问题，难以满足人们对健康管理的实时性和便捷性需求。
基于 STM32F103C8T6 单片机的健康监测系统，整合了心率血氧检测模块、红外测温模块、按键、OLED 显示模块、声光报警装置及短信发送模块，实现了对人体健康状态的自动化监测与智能预警。系统核心功能包括：通过心率血氧检测模块实时监测用户的心率和血氧水平，当心率或血氧不在设定范围内时，启动声光报警装置进行提醒，并发送短信告知相关人员；通过红外测温模块获取用户体温，当体温超出设定阈值时，触发声光报警且发送短信；支持通过按键设置心率、血氧、体温的各参数阈值，以及控制监测的启动和关闭；通过 OLED 显示模块实时显示心率、血氧、体温的测量值。
该系统的实现，有效提升了健康监测的自动化与便捷性水平，减少了人工操作，确保了健康数据的实时监测与及时预警，为个人健康管理提供了高效、可靠的解决方案，同时为同类健康监测设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the continuous improvement of people’s health awareness, real-time monitoring and timely intervention of personal health status have become increasingly important. Traditional health monitoring methods often rely on manual recording and regular physical examinations, which have problems such as delayed data and inability to warn in a timely manner, making it difficult to meet people’s needs for real-time and convenient health management.
The health monitoring system based on the STM32F103C8T6 microcontroller integrates a heart rate and blood oxygen detection module, an infrared temperature measurement module, buttons, an OLED display module, an acousto-optic alarm device, and a short message sending module, realizing automatic monitoring and intelligent early warning of human health status. The core functions of the system include: real-time monitoring of the user’s heart rate and blood oxygen levels through the heart rate and blood oxygen detection module, and when the heart rate or blood oxygen is not within the set range, activating the acousto-optic alarm device for reminder and sending a short message to relevant personnel; obtaining the user’s body temperature through the infrared temperature measurement module, and when the body temperature exceeds the set threshold, triggering the acousto-optic alarm and sending a short message; supporting the setting of various parameter thresholds for heart rate, blood oxygen, and body temperature through buttons, as well as controlling the start and stop of monitoring; real-time display of the measured values of heart rate, blood oxygen, and body temperature through the OLED display module.
The implementation of this system effectively improves the level of automation and convenience of health monitoring, reduces manual operations, ensures real-time monitoring and timely early warning of health data, provides an efficient and reliable solution for personal health management, and also offers a reference for the research and development of similar health monitoring equipment, with high practical application value.
