Abstract: In order to solve the problem that the traditional monitoring mode can not accurately and real-time monitor the atmospheric environment data of various regions, an air environment monitoring system of Internet of things based on SCADA (Supervisory Control And Data Acquisition) system is designed. The system uses a
portable gas monitor as the slave computer to collect atmospheric pollutant concentrations, uses configuration software to build a central monitoring platform to collecting and analyzing thereceived data. The system realizes receiving data from the slavecomputer, realizes data storage with the server, and realizes real-time data monitoring and historical data inquiry. The system can monitor the changes of atmospheric environment of nodes in real time, and can also query the historical data of monitoring nodes and generate historical reports. It has the functions of collecting data, storing data and pre-warning of gas concentration. The system solves the problems that the traditional monitoring system can not refine the monitoring scope and the monitoring data can not be updated and released in real time, and it provides technical support for more convenient, real-time and efficient monitoring of the atmospheric environment.
