摘要
在日常健康管理和疾病预防中，体温作为人体重要的生理指标，其变化能及时反映身体的健康状态。无论是家庭日常监测、学校集体体检，还是疫情期间的体温筛查，准确、便捷的体温监测都至关重要。若体温异常不能被及时发现和关注，可能会延误疾病的诊断与治疗，尤其是对于儿童、老人等特殊群体，潜在风险更大。因此，研发一种操作简便、监测精准且具备异常提醒功能的体温监测设备具有重要意义。
本设计提出一种基于 STM32F103C8T6 单片机的体温监测系统。系统主要功能包括：通过MLX90614 体温监测模块非接触式监测当前用户的体温；用户通过按键设置体温的最大值和最小值阈值，并启动测量流程；当监测到体温大于最大值或小于最小值时，系统触发声光报警模块发出提醒；通过OLED 显示屏实时显示当前用户的体温数值；同时，系统通过WiFi 模块将监测数据上传至阿里云平台，平台可存储体温监测的历史数据，并支持生成折线图或表格，便于用户追溯体温变化趋势。
该系统的作用在于，为用户提供了一种精准、便捷的体温监测解决方案。通过实时监测、异常报警和数据存储分析，能够帮助用户及时掌握体温变化情况，为健康管理和疾病预防提供可靠依据，提升健康监测的效率与科学性。

Design of Body Temperature Monitoring System Based on Single Chip Microcomputer
Abstract
In daily health management and disease prevention, body temperature is an important physiological indicator of the human body, and its changes can timely reflect the health status of the body. Accurate and convenient temperature monitoring is crucial, whether it is daily home monitoring, school group physical examinations, or temperature screening during the epidemic. If abnormal body temperature cannot be detected and monitored in a timely manner, it may delay the diagnosis and treatment of diseases, especially for special groups such as children and the elderly, with greater potential risks. Therefore, it is of great significance to develop a temperature monitoring device that is easy to operate, accurately monitors, and has abnormal reminder function.
This design proposes a temperature monitoring system based on STM32F103C8T6 microcontroller. The main functions of the system include: non-contact monitoring of the current user’s body temperature through the MLX90614 temperature monitoring module; The user sets the maximum and minimum temperature thresholds for body temperature through buttons and initiates the measurement process; When the body temperature is detected to be greater than the maximum value or less than the minimum value, the system triggers the sound and light alarm module to issue a reminder; Real time display of the current user’s body temperature value through OLED display screen; At the same time, the system uploads monitoring data to the Alibaba Cloud platform through the WiFi module. The platform can store historical data of body temperature monitoring and support the generation of line charts or tables, making it easy for users to trace the trend of body temperature changes.
The function of this system is to provide users with a precise and convenient temperature monitoring solution. Through real-time monitoring, abnormal alarms, and data storage analysis, it can help users timely grasp changes in body temperature, provide reliable basis for health management and disease prevention, and improve the efficiency and scientificity of health monitoring.
