摘要
基于STM32单片机的模块化设计,构建了一套老年人健康监测与跌倒定位报警系统。该系统集成了SIM800C移动通信模块和GPS定位模块,配备了体温、心率、步数等传感器,实时监测老年人的健康数据,在数据异常时快速报警;基于E4A平台开发了远程云监测应用程序,实时监测老年人的身体状态;在老人意外摔倒且在一定时间内未能起身时,会自动呼叫被绑定监护人的手机,并发送短信显示老人的位置和状态。实验结果表明,该系统能较好地保障老年人的健康,能正确识别大部分跌倒状态,虚警报率和漏警报率较低,可有效判别跌倒和日常生活行为,具有较高的稳定性和可靠性。
A set of elderly health monitoring and fall location alarm system is constructed based on the modular design of STM32 microcontroller.The system integrates a SIM800C mobile communication module and a GPS positioning module,equipped with sensors such as body temperature,heart rate,and step count,to monitor the health data of the elderly in real-time and quickly alert when the data is abnormal.A remote cloud monitoring application is developed based on the E4A platform to monitor the physical condition of elderly people in real-time.When an elderly person accidentally falls and fails to get up within a certain period of time,the phone of the bound guardian will be automatically called and a text message will be sent to display the elderly persons location and status.The experimental results show that the system can effectively protect the health of the elderly,accurately identify most fall states,have low false alarm rates and missed alarm rates,and can effectively distinguish falls and daily life behaviors,with high stability and reliability.
