Embodiment Construction

[0053] The embodiment of this application provides a method for determining the source of azimuth information. In the embodiment of this application, parameters such as wind speed and wind direction are monitored, and the concentration contribution of local emissions and the concentration contribution of regional transmission are respectively compared with parameters such as wind speed and wind direction. Combined, and then draw the corresponding vector diagram to analyze the orientation of the pollution source, this method is helpful to analyze the real emission source and the orientation of the emission source.

[0054] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present invention and the above drawings are used to distinguish similar objects, and not necessarily Used to describe a specific sequence or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the...

Abstract

The embodiment of the invention discloses an information source determination method comprising the steps that the time period to be analyzed is determined; the pollutant concentration information ofthe target monitoring point in the time period to be analyzed is acquired; the regional background concentration of each sampling moment obtained through the interpolation method within the time period to be analyzed is acquired; the local emission contribution observed by the target monitoring point is determined according to the pollutant concentration information and the difference value of theregional background concentration of each sampling moment within the time period to be analyzed; the two-dimensional wind vector information of the time period to be analyzed is acquired; and the location of the pollutant is determined according to the regional background concentration of each sampling moment within the time period to be analyzed, the local emission contribution and the two-dimensional wind vector information. The local emission concentration contribution and the regional transmission concentration contribution are combined with the wind speed, the wind direction and other parameters and then the corresponding vector diagram is drawn so that the real emission source and the location of the emission source can be analyzed by the method.

Description

technical field [0001] The present application relates to the field of environmental monitoring, in particular to a method for determining an information source and an information source determining device. Background technique [0002] Atmospheric environment is closely related to human life, so air pollution is an important problem facing human beings to be solved. As a kind of fluid, the atmosphere is always flowing and moving, which makes the air pollutants quickly mix with the ambient background atmosphere once they are discharged from the pollution source. [0003] Parameters affecting atmospheric flow include wind speed, wind direction, turbulence intensity, etc. During the flow of the atmosphere, the pollutants emitted by the pollution sources will quickly be mixed with the background atmosphere, thereby increasing the environmental concentration of the pollutants and causing air pollution. When the environmental concentration exceeds a certain value, it will also ...
