Pesticide liquid deposition parameter monitoring system and method for aviation pesticide application

Abstract

The embodiment of the invention provides a pesticide liquid deposition parameter monitoring system and method for aviation pesticide application. The system comprises an aviation spraying device, a sensor monitoring node, data acquisition equipment, and a system management computer; a mixed solution of fluorescent tracer and the pesticide application solution is placed in the aviation spraying device, and the aviation spraying device is used for spraying the mixed solution to a target region; the sensor monitoring node is used for collecting fogdrop of the mixed solution sprayed by the aviation spraying device and acquiring a fogdrop fluorescence image according to the fluorescence emitted by the fluorescent tracer under the irradiation of the laser light source at the preset waveband, andsending the fogdrop fluorescence image to the system management computer through the data acquisition equipment; the system management computer is used for processing the fogdrop fluorescence image,and acquiring a fogdrop deposition parameter corresponding to each fogdrop fluorescence image. The system provided by the embodiment of the invention is convenient for operation, good in continuity, high in collection efficiency, precise in a collection result, strong in instantaneity, and capable of quickly acquiring and analyzing the change process of the fogdrop deposition parameter.

Description

technical field [0001] The embodiments of the present invention belong to the technical field of intelligent agriculture, and more specifically, relate to a system and method for monitoring deposition parameters of aerial pesticide solution. Background technique [0002] In the spraying process of aerial plant protection operations, the ground deposition characteristics of liquid spray droplets, such as droplet coverage, droplet size and distribution, drift distance, deposition rate, etc., directly affect the final control effect of pests and diseases. Therefore, obtaining and analyzing the ground deposition characteristics information of droplets provides a basis for optimizing aerial spraying equipment and technical solutions. [0003] At present, the acquisition methods of ground deposition characteristics of aerial pesticide spray droplets mainly include coloring method and elution method. Among them, the coloring method is to lay water-sensitive paper on the ground, sa...
