Example Embodiment

[0024] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0025] Based on the difference of time curves of different pollution source concentrations, the present invention proposes classification based on time-varying concentration characteristics. like figure 1 As shown, the classification method of hot spot grid pollution type proposed by the present invention includes:

[0026] Obtain the historical concentration data of pollutants in each hotspot grid, and calculate the concentration characteristics of each hotspot grid over time;

[0027] Determine the pollution type of each hotspot grid based on on-site monitoring;

[0028] establishing a mathematical model, and using the time-varying concentration characteristics of each of the hotspot grids and the...

Abstract

The invention discloses a classification method of hotspot grid pollution types. The method comprises the following steps: acquiring historic concentration data of pollutant of each hotspot grid, calculating concentration features of each hotspot grid varying with time; determining the pollution type of each hotspot grid according to on-site monitoring; building a mathematic model, training with the concentration features of each hotspot grid varying with time and corresponding pollution type; obtaining pollutant concentration data of each hotspot grid monitored in real time, calculating the concentration features varying with time, inputting the concentration features into the trained mathematic model, and obtaining the pollution type of the hotspot grid. The method provided by the invention can improve accuracy of pollution type classification, improve supervision efficiency and save labor force.

Description

technical field [0001] The invention belongs to the field of air pollution monitoring, and in particular relates to a method for classifying pollution types of hot spot grids. Background technique [0002] Air pollutants refer to those substances that are discharged into the atmosphere due to human activities or natural processes and have harmful effects on people and the environment, such as: particulate matter: refers to liquid and solid substances in the atmosphere, also known as dust, such as pm2.5, sulfur Oxides: the general term for sulfur oxides, including sulfur dioxide, sulfur trioxide, disulfur trioxide, sulfur monoxide, etc. Carbon oxides: mainly carbon monoxide. Nitrogen oxides: the general term for nitrogen oxides, including nitrous oxide, nitrogen monoxide, nitrogen dioxide, nitrogen trioxide, etc. Hydrocarbons: Compounds formed of carbon and hydrogen, such as methane, ethane and other hydrocarbon gases. Other harmful substances: such as heavy metals, fluori...
