基于STM32的无负荷式睡眠监测系统设计

Design of zero-load sleep monitoring system based on STM32

近年来睡眠健康问题引起了人们的广泛关注.为了科学评估睡眠质量状况,本文基于STM32F407微处理器设计了一种无负荷式睡眠监测系统.系统主要由压电薄膜传感器模块、无线通信模块、OneNET云服务平台模块组成.传感器模块对睡眠过程中的呼吸、心跳、体动、鼾声等信息进行采集,经信号调理电路与A/D转换电路处理后由无线通信模块传输至云服务平台.监测者可通过登录云服务平台查询睡眠状态.本系统软硬件结构清晰,具有较好的应用价值.

Sleep health has attracted wide attention in recent years. In order to monitor sleep quality, this paper designs a zero-load sleep monitoring system based on STM32F407. It consists of piezoelectric film sensor module, wireless communication module and OneNET cloud service platform module. Sensor module collects breathing, heartbeat, body movement and snoring during sleep. Signals are processed by conditioning circuit and A/D conversion circuit, and transmitted by wireless communication module to cloud service platform. Monitors can log on to the cloud service platform to query sleep status. The system has clear structure and good application value.
