Abstract

The invention relates to an air pollutant monitoring and early-warning method and an air pollutant monitoring and early-warning cloud platform. The air pollutant monitoring and early-warning cloud platform comprises a data acquisition module, a data processing platform and a communication module, wherein the data acquisition module is used for acquiring a pollutant concentration in the air, a wind direction and a wind speed; the data processing platform is used for acquiring data output by the data acquisition module, adopting a puff orbit model for conducting three-dimensional flow field simulation, correcting error data through utilizing fitted historical pollutant concentration and wind speed monitoring data, predicting a pollutant concentration at a fixed location in future and calculating an air pollution index, and conducting three-dimensional flow field simulation by means of the puff orbit model to obtain pollutant concentration planar distribution by utilizing pollutant concentrations at monitoring points and the wind speed monitoring data for tracking a pollution source precisely; and the communication module is used for connecting a management system in a wired or wireless manner, connecting a user terminal in a wireless manner, and issuing air quality inspection reports, prediction reports, pollutant distribution contour diagrams and possible pollution source locations to the user terminal.

Description

technical field [0001] The invention relates to an air pollutant monitoring and early warning method and a cloud platform. Background technique [0002] With the rapid development of the economy, people's living standards have been continuously improved, but the problem of environmental pollution has gradually become prominent. Inhalable particles and toxic gases seriously threaten people's life and health. In order to solve this problem, relevant departments have issued a series of environmental monitoring standards, such as "Ambient Air Quality Standards", "Ambient Air Quality Monitoring Specifications (Trial)", "Ambient Air Quality Monitoring Specifications (Trial)" and so on. Mature detection technology, booming Internet and cloud computing technology provide comprehensive technical support for real-time monitoring, wireless transmission, intelligent analysis, accurate early warning and timely release of air pollution. [0003] There are a wide variety of air pollution...
