Traditional manual care methods not only rely on the experience and alertness of caregivers but also have problems such as delayed response and untimely care, which are difficult to meet the needs of modern families for refined and intelligent infant care.The baby crib monitoring system based on the STM32F103C8T6 microcontroller integrates SY sound sensor, DHT11 temperature and humidity detection module, YS liquid detection module, BZ infrared sensor, GP2Y10 dust sensor, 3 independent buttons, OLED display, JQ6500 music player module, ECB02 Bluetooth module and executive devices (heating sheet, fan, humidifier, purifier, crib shaking device, etc.), realizing comprehensive monitoring and intelligent response of the environment around the baby crib and the babys state. The core functions of the system include: detecting the babys cry through the SY sound sensor, when the sound is greater than the maximum value, the JQ6500 music player module automatically plays music, the crib shaking device starts to shake the baby crib, and sends a baby cry prompt through Bluetooth; monitoring the ambient temperature and humidity with the DHT11 temperature and humidity detection module, controlling the heating sheet or fan for heating or cooling when the temperature is abnormal, and using the humidifier or fan for humidification or dehumidification when the humidity is abnormal; detecting whether the baby wets the bed with the YS liquid detection module, and sending a prompt message through Bluetooth when the humidity is greater than the maximum value; detecting whether the baby sits up or stands on the bed through the BZ infrared sensor, and sending a prompt through Bluetooth if so; detecting the PM2.5 content around the baby through the GP2Y10 dust sensor, turning on the purifier when it exceeds the threshold, and sending a prompt through Bluetooth; supporting the setting of temperature and humidity upper and lower limits, maximum sound value, maximum humidity value through 3 independent buttons, as well as manual control of music playback, heating, cooling, humidification, dehumidification, and crib shaking; real-time display of various measured values through the OLED display; transmitting data to the mobile phone through the ECB02 Bluetooth module, and also setting temperature and humidity thresholds, maximum sound value, and maximum liquid level on the mobile phone.The implementation of this system effectively improves the automation and intelligence level of infant care, reduces manual intervention, ensures timely response to various needs of infants, creates a safe and comfortable environment for infants, provides an efficient and reliable auxiliary tool for family caregivers, and also provides a reference for the research and development of similar infant care equipment, with high practical application value.Keywords:STM32F103C8T6; Baby crib; Monitoring system; Sensor; Intelligent response; Bluetooth communication目录第 1 章 绪论1.1 研究的目的及意义1.2 国内外发展情况1.3 本文主要研究内容第2章 设计思路与方案论证2.1 主要元器件选择2.1.1 主控芯片选择2.1.2 声贝传感器选择2.1.3 温湿度检测模块选择2.1.4 液体检测模块选择2.1.5 红外传感器选择2.1.6 粉尘传感器选择2.1.7 音乐播放模块选择2.1.8 显示模块选择2.1.9 蓝牙模块选择2.1.10 按键模块选择2.2整体设计方案第 3 章 硬件设计3.1 主控电路模块3.2 声贝传感器电路3.3 温湿度检测模块电路3.4 液体检测模块电路3.5 红外传感器电路3.6 粉尘传感器电路3.7 音乐播放模块电路3.8 显示模块电路3.9 蓝牙模块电路3.10 按键模块电路3.11 执行设备驱动电路第4章 系统程序设计4.1 编程软件介绍4.2 系统主流程设计4.3 独立按键4.4 OLED显示流程设计4.5 蓝牙模块子流程4.6 ADC模数转换子流程设计4.7 温湿度检测模块子流程设计第 5 章 实物测试5.1 整体实物测试5.2 声贝传感器功能测试5.3 温湿度检测模块功能测试5.4 液体检测模块功能测试5.5 红外传感器功能测试5.6 粉尘传感器功能测试5.7 蓝牙模块功能测试5.8 按键设置与显示功能测试第 6 章 总结与展望6.1 总结6.2 展望致谢参考文献附录附录一原理图附录二PCB附录三主程序
