Atmospheric pollutant real-time analysis and accounting method and system based on electric power and big data

The invention provides an atmospheric pollutant real-time analysis and accounting method and system based on electric power and big data, and the method comprises the steps: determining a user group range of monitoring analysis, and recognizing a target enterprise in the system; acquiring data of the target enterprise at a fixed time period; preprocessing the data, and controlling factors in each link; constructing a model according to the existing power consumption, the real-time discharge capacity and the list discharge capacity data, and training a BP neural network model; inputting meteorological data of a to-be-tested enterprise into the trained model, and outputting a fitting result of atmospheric pollutants of the day; and calculating AQI (air quality index) by using the calculated discharge amount of each atmospheric pollutant in combination with meteorological data, comparing the AQI with a unified early warning grading standard, and performing early warning. According to the calculation method provi
