基于多传感器与无线通信的空巢老人智能监护系统

Intelligent Monitoring System for Empty Nesters Based on Multi-sensor and Wireless Communication

针对现有监护设备存在功能单一、应用场景局限和人机交互不足等问题,研发了一种空巢老人智能监护系统。该系统综合利用多传感器和无线通信技术,设计了可穿戴的主机和固定在床边的从机。主机具备心率、跌倒与定位监测等功能,而从机可监测老人的睡眠质量与环境安全,如有异常及时报警。主从机监测数据可通过近端液晶屏显示和远程手机应用程序端显示,便于老人自己查看和监护人远程监护。测试结果表明,该系统能有效对空巢老人的日常生理参数和生活状态进行实时监测,总体准确率高达98.75%,误报警率仅0.57%。该系统具有多功能、多场景、人机交互多样化等优点,应用前景广泛。

Aiming at the problems of existing monitoring equipment,such as single function,limited application scenarios and insufficient human-computer interaction,an intelligent monitoring system for empty nesters was developed.The multi-sensor and wireless communication technology was applied in the system to design the wearable host module and slave module fixed at the bedside.The host module has the functions of heart rate,fall and positioning monitoring,while the slave module can monitor the sleep quality and environmental safety of the elderly,and gives an alarm in time if there is any abnormality.The monitoring data of master-slave computer can be shown on the near LCD screen and the remote mobile application,which is convenient for the elderly to view and the guardian to monitor.The test results show that the system can effectively monitor the daily physiological parameters and living conditions of empty nesters in real time.The overall accuracy rate is as high as 98.75%,and the false alarm rate is only 0.57%.The system has many advantages,such as multi-function,multi-scene and diverse human-computer interaction,and has a wide application prospects.
