Atmospheric pollutant tracing method based on longicorn beard search algorithm

Abstract

The invention provides an atmospheric pollutant tracing method based on a longicorn beard search algorithm. The atmospheric pollutant tracing method is used for quickly and accurately positioning atmospheric pollutants under the condition that wind direction information is unknown. At present, most existing smell source positioning algorithms need to depend on wind direction information upwind search to track smoke plume, the algorithms have strong dependence on wind direction information, the fluctuation amplitude of actual wind speed and wind direction is large, the diffusion of odor sourcesin the air is greatly influenced, so referring the wind direction information and positioning the odor sources by utilizing the wind tendency, the search effect is poor, the robot is easy to fall into local optimum in the search process, and the search efficiency is low. According to the atmospheric pollutant tracing method based on a longicorn beard search algorithm, gas sensors are carried at the left end and the right end of an unmanned aerial vehicle respectively, pollutant concentrations at the left end and the right end of the unmanned aerial vehicle are read in real time, the next position of the unmanned aerial vehicle is judged through the longicorn beard search algorithm, and then continuous iteration is performed to gradually approach a pollution source. According to the algorithm, under the condition of not depending on wind direction information, the unmanned aerial vehicle is effectively prevented from falling into local optimum in the searching process, and the positionof a pollution source is accurately and rapidly positioned.

Description

technical field [0001] The present invention relates to a method for locating pollution sources, in particular to a method for tracing the source of air pollutants based on a beetle beetle search algorithm. Background technique [0002] In recent years, the problem of air pollution has become increasingly serious. Up to now, there are more than one billion urban residents in the world who live in different levels of air pollution. This atmospheric environment can induce a variety of respiratory and even other diseases, which is harmful to the health of residents posed a serious threat. Due to the strong mobility of the air, and in order to discharge the exhaust gas to a farther place and avoid local pollution, factories in various places adopt the method of high chimney and remote emission, which expands the scope of air pollution. It is difficult to control the flow of polluted air, and the whole world is under the threat of air pollution. Therefore, the location of air p...
