摘　　要：针对卧床老人的监测需求,以及目前监测系统通信距离短、功耗大和成本高等缺点,提出了一种基于NB-IoT的卧床老人监测系统。系统以GD32F103C8T6单片机为控制器,使用多传感器检测卧床老人的血压、心率、体表温度及居室环境参数。当采集的数据超过预设值时,报警器报警。采用NB-IoT技术,通过LwM2M协议与OneNET云平台连接,将采集的体征和居室数据上传至OneNET云平台,OneNET云平台可接收和下发数据。客户端可实时监测卧床老人的体征参数、居室安全信息,以及进行远程报警控制。经过测试,系统能够实现对卧床老人的远程监测,具有功耗低、成本低等特点。Aiming at the needs of monitoring the bedridden elderly and the shortcomings of the current monitoring system,such as short communication distance,high power consumption and high cost,a monitoring system for the bedridden elderly based on NB-IoT is proposed.The system uses the GD32F103C8T6 single chip microcomputer as the controller,and uses multi⁃sensor to detect the blood pressure,heart rate,body surface temperature and room environment parameters of the bedridden elderly.When the collected data exceeds the preset value,the alarm will alarm.NB-IoT technology is adopted to connect with OneNET cloud platform through LwM2M protocol,and the collected physical signs and room data are uploaded to OneNET cloud platform,which can receive and send data.The client can real⁃time monitor the physical parameters and room safety information of the bedridden elderly,and carry out remote alarm control.After the system test,it can realize the remote monitoring of the bedridden elderly,and has the characteristics of low power consumption and low cost.
