Spray control method and system based on volume feature pre-judging

Abstract

The invention discloses a spray control method based on volume feature pre-judging. The method comprises the following steps: the distance detection of the plant canopy on one side or both sides of the sprayer is carried out by using some distance detection points based on the center line of the sprayer body when the spray zone begins; the canopy width corresponding to the detection point is calculated; the maximum canopy width of a canopy partition is used as the width of the discrete spray volume of the canopy partition; the discrete canopy volume of each canopy partition is calculated; theamount of spray and air volume required for the next spray partition is calculated. The invention also discloses a spray control system based on volume feature pre-judging. The method can adjust the spray amount in time and accurately by detecting the spray object and pre-judging the volume in advance and add the precise bypass air regulation fuction which can increase the penetration and deposition amount of the liquid and reduce the spray waste.

Description

technical field [0001] The invention belongs to the technical field of agricultural spraying operations, and in particular relates to a spraying control method and system based on volume characteristic prediction. Background technique [0002] At present, most of the agricultural pesticide spraying methods in my country are manual, and some pesticide application methods are mechanical spraying. The common problem in the existing agricultural spraying technology is that the utilization rate of pesticides is low, and most of the pesticides are lost in the air after spraying. Neutralize or deposit on the ground, resulting in the waste of pesticides and environmental pollution. Therefore, it is an important task to improve the level of pesticide spraying in my country and to conduct research on pesticide spraying technologies with high efficacy, low spray volume, and high deposition. Variable variable spray technology is an advanced spray technology in the world at present, but f...

[0002] At present, most of the agricultural pesticide spraying methods in my country are manual, and some pesticide application methods are mechanical spraying. The common problem in the existing agricultural spraying technology is that the utilization rate of pesticides is low, and most of the pesticides are lost in the air after spraying. Therefore, it is an important task to improve the spraying level of pesticides in my country and to carry out research on pesticide spraying technology with high efficiency, low spray volume and high deposition.

Variable variable spray technology is an advanced spray technology in the world at present, but for the situation of spraying in progress, the spray object is constantly changing, which leads to many problems in the existing variable spray technology. First, the variable adjustment is relatively There is a lag in the change of the spray object, and it is impossible to adjust the spray variable in time according to the change of the spray object; second, the perception of the shape or size of the spray object is not accurate enough, which makes the variable adjustment less targeted and reduces the spray effect to a certain extent The third is that although the spray variable adjustment can be carried out to a certain degree, it is still unsatisfactory in terms of improving the penetration and deposition of the liquid medicine, reducing spray waste, etc.
