Automatic source searching method for environmental pollution

The invention discloses an automatic source searching method for environmental pollution, and belongs to the technical field of automatic control trajectory tracking. According to the invention, a detection module, a high-precision positioning module and a wireless communication module are carried at an unmanned aerial vehicle end, so that beyond-visual-range monitoring of pollutants is realized;meanwhile, the data acquired by the unmanned aerial vehicle is analyzed and processed by combining MATLAB software; concentration of the pollutants at each point is calculated through a pollutant concentration formula, a pollutant diffusion path is analyzed, and a flight path of the unmanned aerial vehicle is controlled in combination with concentration gradient information, so that position information of a pollution source is determined and fed back, an automatic source searching process is completed, the maneuverability is high, the detection range is wide, and the unmanned aerial vehicle is not limited by sites. 本
