| For the health monitoring scenario based on the Internet of Things: Traditional health monitoring used GSM,3G or 4G transmission methods to monitor health parameters,but due to poor monitoring signals,high power consumption,and high cost,health monitoring has developed slowly,This subject designed a home remote health monitoring system based on NB-Iot.A monitoring method based on the combination of NB-Iot and cloud platform was proposed.Through experimental verification,this method can achieve wide coverage,low power consumption and low cost of the health monitoring system.Based on the research of NB-Iot transmission,combined with sensor technology and Internet technology,the system realized remote viewing of health monitoring information of elderly users,real-time recording of movement status and movement trajectory,and fall alarm.The system consisted of terminal equipment platform,OneNET,mobile phone client and PC terminal,where the terminal equipment platform included data acquisition and processing unit and NB-Iot network transmission unit.First collected blood pressure,blood oxygen,heart rate,exercise status and corresponding positioning information of elder users through blood oxygen collection sensor MAX30102,blood pressure and heart rate sensor MKB0803,BDS sensor ATGM336H-5N and motion sensor GY521-MPU6050,and realized the communication between the terminal device platform and the OneNET through NB-Iot module M5310-A.In the Altium Designer 09 hardware development environment,the circuit and PCB design of the terminal device platform with the low-power chip STM32L151C8T6 as the core was completed;secondly,the software design was completed based on KEIL5 including data collection,processing and transmission to OneNET of terminal equipment platform;again,the design and development of third-party software platforms were implemented on the basis of the OneNET,including Android application software developed based on the AndroidStudio platform and Web application software developed based on the Eclipse platform,enabling remote viewing of health monitoring information for elderly users,Real-time recording of movement status and trajectory and fall alarm and other functions;Finally,the system was tested for function and performance.The test results showed that the system can accurately collect and process data and maintain well communication with the software platform,at the same time had high reliability,and its low power consumption performance meeted the design requirements.This system had a positive research significance for the development of home-based smart old-age care under the Internet of Things environment. |
