Design And Implementation Of Air Pollution On-line Monitoring System

In recent years,China’s economy has developed rapidly and the process of urbanization has accelerated,which has made a qualitative leap in people’s quality of life,but the country has also paid a high environmental price.For example,environmental pollution is becoming more and more serious.Among them,the problems of air pollution are becoming more and more prominent,and smog weather occurs frequently.Serious smog weather will not only have a great impact on the normal social production and living order,but also do great harm to human health.Therefore,the problem of air pollution has attracted extensive attention of the whole society,and the financial support from the central government to the local government is increasing,Promote the increasing research in air pollution related fields.In 2020,the Ministry of ecology and environment has started the preparation of the special plan for the prevention and control of air pollution in the 14th five year plan.In terms of goal setting,it will continue the ideas of "ten articles for the atmosphere" and "three-year action plan for the defense of the blue sky",further improve the ability of environmental monitoring,law enforcement and supervision,and promote the modernization of atmospheric environment management system and governance ability.Under the above background,entrusted by the researchers of a metrology research institute,this thesis designs and implements a set of air pollution online monitoring system based on HJ 212-2017 pollutant online monitoring(monitoring)system data transmission standard,which realizes the effective monitoring and data analysis of air pollutant concentration.This thesis designs and implements a data acquisition micro service based on HJ 212-2017 transmission standard.All atmospheric environment monitoring equipment using the transmission standard can communicate with the system by setting the IP address and port number of sending monitoring data packets,and adding thread pool technology to solve the problem of data concurrency.After obtaining the monitoring data packets,according to HJ 212-2017 transmission standard,Finally,the unstructured data package is parsed and stored into the corresponding unstructured data table through the command.Based on these data,the web page and applet of the system are designed and implemented.Springboot+JPA framework is adopted in the background of web side and applet side,and Vue.js technology is adopted in the foreground of web side,the foreground of the applet side uses uni-app technology to design and implement.The function of the web side is comprehensive,and the basic information management module is designed and implemented to realize the information management of users,locations,monitoring equipment and filter membrane weighing data;The command message is sent by assembling the data packet,and the system is used to remotely set the parameters of the monitoring equipment;Add the exception handling function to alarm and prompt the abnormal monitoring data through the front-end or short message;Visually display the statistical data and the obtained monitoring data to help users better analyze and monitor the atmospheric environment;Design concentration prediction model to predict hourly PM2 5 concentration and give early warning of air pollution.The applet side is convenient and fast.Its main purpose is to facilitate researchers to view monitoring data in real time,manage basic information and view abnormal record history.Up to now,the function points in this platform have been realized and basically meet the needs in the actual use process.It can better serve the researchers’ needs for pollutant concentration monitoring and data analysis in the air.I believe this platform will play a greater role in the future.
