Design And Implementation Of A Breathing Gas Detection System Based On Cloud Platform

With the deepening of technologies such as big data and cloud computing,cloud services can enter people's lives,People can purchase cloud services like water,electricity and gas to provide people with on-demand computing needs,and cloud services can serve people through the high-performance computing power of cloud computing and massive data storage.The continuous deepening of information technology has enabled the rapid development of intelligent mobile terminal devices,and the mobilization of PC services has become an irresistible trend.The combination of cloud computing and mobile smart devices has created a new paradigm,mobile cloud computing,which aims to use cloud computing technology to store and process data on mobile devices,thereby reducing the limitations of mobile device usage.This paper develops a respiratory gas detection system based on cloud platform for the shortcomings of the current respiratory gas detection instruments,which are expensive and not suitable for individual users.The system consists of two parts: a hardware system and a software processing system.For the hardware system part,this paper designs a breathing detection device,which includes MEMS gas sensor,differential pressure airflow sensor and various gas detection functions suitable for ergonomics,the gas data detected by the device will eventually be transferred to the software system for processing.For the software processing system,the system is divided into two parts: Android client and cloud server.Android client is developed under the Android Studio platform by using Android SDK development tools and development languages such as XML and Java,the functions of user login registration,connection to Bluetooth,saving data,tagging files,uploading data to OSS,returning data display,etc.are realized,and the function of computing using cloud service in mobile intelligent terminal is realized.The cloud server uses Alibaba Cloud Server(Ubuntu 16.04)and runs the Java Web project on the Linux system.The Java Web project uses the eclipse platform to develop using Servlet,JSP and Java frameworks,and uses BP neural network to process and Forecast data.The cloud server part also involves operations such as Putty connection ECS,Ossfs mounting OSS storage,and FileZilla viewing Linux directories.In this design,the Android client communicates with the hardware system using Bluetooth communication,and the Android client communicates with the cloud server using HTTP communication.After repeated system tests,the functional modules of each part of the software designed in this paper have met the design requirements,which has a high reference value for the improvement and practical application of the respiratory gas detection system.
