摘 要
随着人口老龄化的加剧，老人睡眠健康成为社会关注的焦点。为有效监测老人的睡眠状况，本文设计并实现了一款基于STM32F103C8T6单片机的老人睡眠检测系统。该系统集成了多种传感器，旨在全面、准确地监测老人的睡眠状态与健康参数。
系统通过心率检测模块实时监测老人的心率，反映其睡眠中的心脏健康状况；利用呼吸率传感器精确测量呼吸速度，了解老人的呼吸平稳度；DHT11传感器用于检测睡眠环境的温湿度，确保睡眠环境的适宜性；MPU6050传感器则用于监测老人的翻身次数，分析其睡眠过程中的翻身活动状况。体温监测模块与声音监测模块，分别用于监测老人的体温变化与是否打呼，为评估其整体健康状况提供重要依据。通过按键设置心率、呼吸率、体温等参数的上下阈值，一旦监测数据超出预设范围，系统将立即进行声光报警，及时提醒家属或护理人员关注老人状况。并通过WiFi模块将监测数据实时传输至手机端，用户在手机端不仅可以实时查看老人的睡眠监测数据，还可以远程设置参数阈值、控制设备的报警状态，实现老人睡眠检测系统的远程管理与监控。
该系统的设计与实现，不仅为老人提供了全方位的睡眠健康监测，还为家属和护理人员提供了便捷、高效的健康管理工具。通过实时监测与数据分析，系统能够及时发现老人的睡眠健康问题，为及时采取干预措施提供了有力支持。

Abstract
With the intensification of population aging, the sleep health of the elderly has become a focus of social attention. To effectively monitor the sleep status of the elderly, this article designs and implements an elderly sleep detection system based on STM32F103C8T6 microcontroller. The system integrates multiple sensors aimed at comprehensively and accurately monitoring the sleep status and health parameters of the elderly.
The system monitors the heart rate of the elderly in real-time through a heart rate detection module, reflecting their heart health status during sleep; Accurately measuring respiratory rate using a respiratory rate sensor to understand the stability of the elderly’s breathing; The DHT11 sensor is used to detect the temperature and humidity of the sleep environment to ensure its suitability; The MPU6050 sensor is used to monitor the number of times the elderly person turns over and analyze their turning activity during sleep. The temperature monitoring module and sound monitoring module are respectively used to monitor the temperature changes and whether the elderly are breathing, providing important basis for evaluating their overall health status. By pressing buttons to set the upper and lower thresholds for parameters such as heart rate, respiratory rate, and body temperature, once the monitoring data exceeds the preset range, the system will immediately sound and light an alarm to remind family members or caregivers to pay attention to the elderly’s condition in a timely manner. And the monitoring data is transmitted in real time to the mobile phone through the WiFi module. Users can not only view the elderly’s sleep monitoring data in real time on the mobile phone, but also remotely set parameter thresholds and control the alarm status of devices, achieving remote management and monitoring of the elderly sleep detection system.
The design and implementation of this system not only provides comprehensive sleep health monitoring for the elderly, but also provides convenient and efficient health management tools for family members and caregivers. Through real-time monitoring and data analysis, the system can promptly detect sleep health issues in the elderly, providing strong support for timely intervention measures.
