Automatic source searching system for environmental pollution

The utility model discloses an automatic source searching system for environmental pollution, and belongs to the technical field of automatic control trajectory tracking. According to the utility model, the detection module, the high-precision positioning module and the wireless communication module are carried at the 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 pollutants at each point is calculated through a pollutant concentration formula, a pollutant diffusion path is analyzed, and the 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 limit
