Telemetry system and method of pesticide mist distribution and drift trend in aerial pesticide application

Abstract

Disclosed are a remote measurement system and method for pesticide fog distribution and drifting tendency in aerial pesticide application, which relate to the technical field of hazardous substance monitoring. The system comprises: a collection module, used for collecting infrared radiation in a detected area, and enabling the infrared radiation to be incident on an optical module; the optical module, used for obtaining, according to the incident infrared radiation, an infrared imaging spectrum in the detected area where a pesticide fog cloud cluster is distributed, and sending the infrared imaging spectrum to a processing module; the processing module, used for analyzing the infrared imaging spectrum, identifying the pesticide fog cloud, obtaining a concentration image of the pesticide fog cloud through inversion, and predicting a drifting tendency of the pesticide fog according to the concentration image. The system and method of the present invention can comprehensively reflect the drifting condition of the pesticide fog in the air in real time, and can obtain the concentration and components of the pesticide fog. The method and system improve the pesticide application efficiency, and prevent damages on the environment and residential areas while saving the cost.

Description

Technical field [0001] The invention relates to the technical field of hazardous substance monitoring, in particular to a system method for remotely measuring the distribution and drifting trend of pesticide mist in aerial pesticide application. Background technique [0002] Pesticide drift during aerial application is one of the important factors that pollute the environment. Pesticide drift refers to a physical movement in which pesticide droplets or particles migrate from the target area to the non-target area in the air under uncontrolled conditions during the application process or a period of time after the application. Pesticide drift includes evaporation drift and wind drift. drift. The former is caused by the volatility of the effective ingredients of pesticides, while the latter mainly refers to the process in which the fine droplets in the mist flow are carried out of the target area by the airflow and then disappear or settle again. The drift of droplets always inev...

AI Technical Summary

Problems solved by technology

Drift seriously affects the effect of pesticide application and the natural environment: (1) If a uniform circuit spraying method is used, it may cause unevenness of the spraying amount, some areas are not treated with medicine, and some areas are overdosed

To a certain extent, it has caused the waste of pesticides and the incomplete application effect

(2) Most pesticides are toxic, or produce toxic substances and greenhouse gases after degradation

When the gasified mist clouds invisible to the human eye drift outside the spraying area, it will pollute water quality, healthy vegetation, forests, generate greenhouse gases, and cause immeasurable impact on the environment

(3) The drug mist will drift to residential areas under unknown circumstances, causing harm to the health of residents

[0006] (1) Only the drug receiving level of a certain area on the ground can be obtained, which cannot fully reflect the drift of the drug mist in the air;

[0007] (2) poor effectiveness;

[0008] (3) The concentration and composition of dense fog cannot be obtained;

[0009] (4) Unable to detect tiny fog droplets that are always suspended in the air

[0011] (1) Only the collected gas can be analyzed, and the distribution of the drug mist cannot be fully reflected;

[0012] (2) Real-time and continuous monitoring cannot be carried out;

[0013] (3) The sampling and pre-processing process is complicated, time-consuming and laborious;

[0014] (4) It is difficult to complete sampling analysis of high-altitude pesticide mist
