Hebei PM2.5 cloud detector debut

In the future, conventional PM2.5 monitoring, which is currently sampling every 45 minutes, can be broken down to achieve PM2.5 second-level monitoring. At the PM2.5 grid monitoring and real-time warning technology exchange conference recently held by the Hebei Environmental Protection Federation, a new “PM2.5 cloud monitor” was unveiled, and PM2.5 can realize second-level monitoring, that is, monitoring once per second. .

“This kind of real-time warning system can comprehensively, accurately and timely grasp the state and trend of environmental air quality through the deployment of grid-wide city grid control, and achieve rapid response and precise control of atmospheric pollution sources.” Vice President of Hebei Environmental Protection Federation Wang Luguang, the secretary-general, said.

According to reports, the current regular PM2.5 monitoring, sampling once every 45 minutes, released once a hour concentration value. The "PM2.5 Cloud Monitor" sampling time is defined as seconds and the monitoring radius is 1 to 2 kilometers. Because of the high frequency of sampling, it is possible to discover areas where PM2.5 concentration is increasing too fast or the concentration level is too high in the formation of smog. Monitoring data can be transmitted to the cloud computing platform in time through the mobile network and real-time early warning of relevant regions can be achieved. , Take targeted measures, environmental monitoring and other directions for action, improve the accuracy of preventive and control measures, and the accuracy of environmental monitoring.

According to reports, the Hebei Provincial Environmental Protection Federation has launched the “Introducing Intelligence to Build a Beautiful Hebei” project and established a science and technology committee and expert database consisting of top-ranking experts in China. It plans to introduce 10 items within 3 years. The above-mentioned first-class environmental protection high-tech and products at home and abroad. The exchange activity for “PM2.5 Cloud Monitor” was the first technical exchange meeting held by Hebei Environmental Protection Federation.
