Abstract

The invention provides an air quality prediction system. The system comprises a determination unit, a training unit and a prediction unit, wherein the determination unit is configured to determine an adjacent area of a to-be-tested place according to a distance threshold; the training unit is configured to train a prediction model to obtain optimal parameters of the prediction model, and the prediction model is constructed based on a wind direction and according to spatial features of the adjacent area; and the prediction unit is configured to predict the air quality of the to-be-tested place by utilizing the prediction model with the optimal parameters. The invention furthermore provides an air quality prediction method. According to the air quality prediction method and system, a wind direction factor is combined with geographic information, so that the relevance among adjacent areas is fully utilized and the accuracy of air pollution prediction is improved.

Description

technical field [0001] This application relates to the field of data analysis, in particular to a system and method for predicting air quality. Background technique [0002] Air pollution and air quality are getting more and more attention. However, due to the high cost and troublesome operation of air pollutant detection equipment, using other environmental information (such as temperature, humidity and visibility, etc.) to predict harmful particles in the air (such as PM2.5, etc.) has extremely high social benefits and Economic Value. [0003] Usually, with the help of pollutant change information such as historical information and adjacent area information, the concentration of pollutants is predicted for future time periods and spaces without on-site detection conditions. In order to predict the concentration, it mainly relies on statistical methods to find sites with similar pollutant concentration distributions and fit the concentrations of the sites to be measured. ...
