Locating method and device and storage medium

Abstract

The embodiment of the application discloses a locating method for accurately locating an emission source. The embodiment method of the application comprises the following steps: obtaining first pollutant concentration information of a first monitoring point; calculating a first azimuth line, wherein the first azimuth line is a connecting line of the first monitoring point and a first high pollution point, the first high pollution point is in the first pollutant concentration information, and the difference value of a concentration value and an environmental background concentration value is greater than a preset threshold point; obtaining second pollutant concentration information of a second monitoring point, wherein the second monitoring point is a monitoring point determined by the first monitoring point and the first high pollution point; calculating a second azimuth line, wherein the second azimuth line is a connecting line of the second monitoring point and a second high pollution point, the second high pollution point is in the second pollutant concentration information, and the difference value of the concentration value and the environmental background concentration valueis greater than a preset threshold pollution point; determining the position of the emission source, wherein the position of the emission source is a crossing point of the first azimuth line and the second azimuth line, therefore, the accuracy of position locating for the emission source is improved.

Description

technical field [0001] The present application relates to the field of measurement, and in particular to a positioning method, device and storage medium. Background technique [0002] Air pollution is a phenomenon that plagues most parts of the world, especially developing countries, seriously affecting the health and visibility of the population. Generally speaking, the spatial distribution of air pollution sources is dense, and the emission time and behavior are extremely variable. Once air pollutants are emitted, they quickly diffuse in the atmosphere, which means that the emissions from pollution sources are quickly diluted by low-concentration background gases, resulting in a rapid drop in concentration. [0003] At present, domestic and international air quality monitoring mainly relies on traditional government-controlled atmospheric monitoring stations. These monitoring stations realize most of the above-mentioned problems by using traditional equipment and the prin...

Problems solved by technology

[0004] In the existing technology, a single monitoring station indirectly infers the location of the emission source by monitoring the concentration of pollutants, but this method cannot accurately locate the source of pollution
