Design And Implementation Of Indoor Air Quality Monitoring Information System In Public Places

At the same time as public environmental thinking and awareness of indoor air pollution,indoor air pollution has also received high attention.However,traditional air purifiers generally use several different colors of light to qualitatively display the current air quality,ignoring the actual amount of the harmful substances in the air and the trend of the dynamic change of the air in the air with the passage of time.Such an air quality display method cannot visually display the specific conditions of the indoor air environment,and is also inconvenient for the collection and subsequent analysis of these indoor gas content data.The continuous maturation of the Internet of Things,sensors,and big data processing technologies in recent years has provided new solutions to solve the existing problems in air detection and purification equipment.That is,we can connect sensors of all kinds of harmful substances into the network,collect and analyze the monitoring data through the server,and finally show the real-time data and dynamic change trend in front of the user.The indoor air quality monitoring information system based on WEB mode uses the monitoring formaldehyde,benzene gas sensor,fine particulate matter(PM2.5),humidity,temperature sensor to collect air monitoring information.Through the network protocol,the collected data are sent to the designated server on the Internet to store and analyze the information.Finally,the data and dynamic charts are updated in the browser end in the form of a comprehensive and intuitive display in front of the users.Through such means and methods,it can more effectively deal with the shortcomings and defects that the traditional air purifier can only qualitatively display the current air quality,and provide evidence for future prediction and control air quality,and realize the air quality data.The ability to collect,monitor,and analyze.The system uses JDK1.8 on the Eclipse platform to develop the JAVA programming language,uses Tomcat as the Web application server and My SQL as the database in Window 7 operating system.
