摘要
在人们对健康愈发重视的当下，身体参数的实时、精准监测对于疾病预防、健康管理具有重要意义。传统的身体参数监测方式多依赖专业设备在固定场所进行，存在检测不便、数据获取滞后、无法实时预警等问题，难以满足人们日常健康监测的需求。
基于 STM32F103C8T6 单片机的身体参数监测系统，整合了 MLX90614 体温传感器、MAX30102 心率检测模块、XGZP6847 血压监测模块、3 个独立按键、OLED 显示屏及声光报警装置，实现了对人体体温、心率、血压的自动化监测与智能预警。系统核心功能包括：通过 MLX90614 实时监测体温，当体温不在设定阈值内时触发声光报警；借助 MAX30102 检测用户心率，心率超出阈值范围时启动声光报警；利用 XGZP6847 监测血压，血压偏离阈值时进行声光报警；支持通过 3 个独立按键设置各参数阈值，以及启停体温、心率、血压的监测功能；通过 OLED 显示屏实时显示检测到的体温、心率、血压数据。
该系统的实现，有效提升了身体参数监测的便捷性与实时性，能够及时发现身体异常并预警，为个人健康管理提供了高效、可靠的解决方案，同时为同类便携式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
In the context of people paying more and more attention to health, real-time and accurate monitoring of body parameters is of great significance for disease prevention and health management. Traditional methods of monitoring body parameters mostly rely on professional equipment in fixed places, which have problems such as inconvenient detection, delayed data acquisition, and inability to provide real-time early warning, making it difficult to meet people’s needs for daily health monitoring.
The body parameter monitoring system based on the STM32F103C8T6 microcontroller integrates MLX90614 temperature sensor, MAX30102 heart rate detection module, XGZP6847 blood pressure monitoring module, 3 independent buttons, OLED display and sound-light alarm device, realizing automatic monitoring and intelligent early warning of human body temperature, heart rate and blood pressure. The core functions of the system include: real-time monitoring of body temperature through MLX90614, triggering sound-light alarm when the body temperature is not within the set threshold; detecting the user’s heart rate with MAX30102, activating sound-light alarm when the heart rate exceeds the threshold range; monitoring blood pressure using XGZP6847, and giving sound-light alarm when the blood pressure deviates from the threshold; supporting the setting of each parameter threshold through 3 independent buttons, as well as starting and stopping the monitoring of body temperature, heart rate and blood pressure; real-time display of detected body temperature, heart rate and blood pressure data through the OLED display.
The implementation of this system effectively improves the convenience and real-time performance of body parameter monitoring, can timely detect physical abnormalities and give early warning, provides an efficient and reliable solution for personal health management, and also offers a reference for the research and development of similar portable health monitoring equipment, with high practical application value.
