Abstract

The invention discloses a detect method of droplet distribution uniformity, which can detect the droplet uniformity in the spray test of sprayer. The inventive method comprises a spray droplet collecting step for collecting the sprayed droplets of a sprayer, a droplet picture pick-up step for using a digit picture pick-up device to pick up the picture of the collected sprayed droplets, a computer droplet picture information obtaining-processing step that the digit picture pick-up device transmits the droplet picture information to the computer for image processing, and a droplet distribution uniformity information obtaining step for obtaining the droplet number and area information according to the result of the image processing to obtain the droplet distribution uniformity information.

Description

technical field [0001] The invention relates to an automatic detection technology, in particular to a detection method for the uniformity of droplet distribution when sprayed by a spray device. Background technique [0002] The uniformity of droplet distribution is one of the main indicators for evaluating spray quality. There are four main measurement methods (see the Machinery Industry Standard of the People's Republic of China JB / T9782-1999 General Test Methods for Plant Protection Machinery). The paper card method is to use 3×5cm 2 The spray liquid is prepared by adding 1% (by weight) black dye to clear water, and the paper card is horizontally clamped on a support with a height of 0.15-1m. The interval (not more than 0.5m) or continuous arrangement, spraying time 2-3s, after spraying, use a magnifying glass to manually observe and count on the paper card, within 3cm 2 Count the total number of droplets on the area, or measure the dye content on it with a spectrophotom...
