Method for monitoring agricultural spraying involving detecting the presence of chemicals in the form of water aerosols in the atmosphere and system for implementation of this method

摘要

A method of monitoring agrotechnical spraying consisting in detection of the presence in the atmosphere of chemical substances in the form of aqueous aerosols and a system for the application of this method consisting in detecting the presence in the atmosphere of chemical substances in the form of aqueous aerosols, using a transmitter and receiver of electromagnetic waves, characterized in that at least 50 impulses of electromagnetic radiation with a wavelength from 600 to 650 nm, preferably 635 nm, modulated by a square wave, preferably with a filling of 50% and a frequency of 1 kHz is passed through the tested area, and then the amplitude of each pulse from the receiving line is determined and the attenuation of electromagnetic radiation beam is determined, and then the pre-defined coefficients of the attenuation of the radiation beam by a water aerosol of an agrotechnical substance used for spraying serve to designate the concentration of the spray in the atmosphere. The solution according to the invention uses an optical system for measuring the transmission, in which electronic modulation of the light is used.
