Environmental monitoring is the foundation of environmental governance, and it has received increasing attention and national policy support. Traditional high-cost, low-density environmental monitoring stations can no longer meet today's monitoring needs. The low-cost, high-density environmental monitoring system that adopts new technology can exert high-efficiency monitoring benefits, and it has become the mainstream development trend of environmental monitoring.
The grid air environment monitoring system adopts the latest sensing technology, which effectively reduces the cost of environmental monitoring. Through the large-scale deployment of monitoring points, high-density monitoring of the regional environment is realized, a grid-based monitoring system is formed, the channel between online monitoring and government supervision is opened, and decision-making support is provided for scientific haze control and precise pollution control. It is conducive to the real-time and accuracy of environmental monitoring and the scientific nature of environmental governance.
1. Monitor multiple atmospheric environmental parameters such as PM2.5, PM10, SO2, NO2, CO, and O3;
2. 24-hour online continuous monitoring, providing all-weather air quality data at the monitoring location;
3. Environmental maps based on monitoring data and GIS technology support data playback and statistical ranking based on time and space, so that personnel can intuitively and globally grasp the environmental situation, and provide decision-making basis and technical support for environmental governance;
4. Relying on the intuitive performance and data playback of the environmental map, the source of pollution can be traced intuitively, and the trajectory of its diffusion and dissipation can be monitored, providing data basis for accurate haze prevention and ensuring data traceability;
5. Provide statistics in various forms such as histogram and line chart, and export various reports such as Excel, XML, TXT, SQL, CSV, JSON, etc.;
6. The system adopts an integrated industrial design, simple and convenient to install, beautiful and generous in appearance, and enhances the city appearance; 7. Automatic alarm, early warning, timely prevention and treatment of pollution.
The gridded atmospheric environment monitoring and management platform can realize GIS map display, historical data query, parameter comparison, time period analysis, data report, site ranking, spatial distribution, classification statistics and other functions through mobile APP and WEB.
Urban environment grid online monitoring system, micro air quality automatic monitoring station, atmospheric grid monitoring equipment product features1. Reasonable structure design, which can simultaneously monitor gas parameters, inhalable particulate matter, meteorological parameters, etc. The standard monitoring parameters are PM2.5, PM10, NO2, SO2, O3, CO, commonly known as "two dust and four gases".
