Abstract
The invention relates to the field of pollutant prediction, in particular to a method and system for estimating atmospheric pollutant emission based on economic big data. The method comprises the steps of obtaining first prediction data through a first prediction algorithm based on economic data; calculating through a second prediction algorithm based on the pollutant satellite data to obtain second prediction data; determining pollutant emission prediction data according to the first prediction data and the second prediction data, wherein the first prediction algorithm comprises a neural network algorithm obtained by training historical economic data and historical pollutant emission data; and the second prediction algorithm comprises a prediction algorithm obtained through regression analysis of historical pollutant satellite data and pollutant emission statistical data. According to the method and system, pollutant emission data is monitored in a prediction mode, and the situation of monitoring failure caused by human factor interference is reduced or eradicated.
Description
technical field [0001] This patent relates to the field of pollutant prediction, specifically to a method and system for estimating air pollutant emissions based on economic big data. Background technique [0002] At present, the monitoring of air pollutant emissions at home and abroad is mainly to install a variety of different sensors in each link, and then collect and analyze multiple parameters of each link. For different pollution-producing enterprises, the pollutant monitoring sensors that need to be placed in each link may be different. By collecting and comparing the data of each sensor to meet the national discharge standards, it is determined whether the pollution control effect of the pollution-producing enterprises meets the standards. [0003] In the prior art, the use of sensors to monitor pollutant emissions has the following problems. The environment of the enterprise's sewage pipes and production links is complex, and it is difficult to install sensors, whic...
