Automatic control method, pesticide spraying device and control system for spraying of biological agents

Abstract

The embodiment of the invention relates to the field of agriculture and discloses an automatic control method, pesticide spraying device and control system for spraying of biological agents. The automatic control method for spraying of pesticide includes the steps of receiving pest and disease information obtained by monitoring crops in a greenhouse, wherein the pest and disease information includes the level of pests and diseases and corresponding position information of the crops; feeding back the pest and disease information to the pesticide spraying device in order to enable the pesticidespraying device to judge whether or not it is needed to carry out pesticide treatment according to the level of the pests and diseases of each crop and the position information of each crop; if yes, establishing a spraying route of the biological agents, wherein the spraying route includes spraying paths, path priorities and spraying points set on each spraying path, and the higher the level of pests and diseases of the crops in one spraying path is, the higher the corresponding path priority is; controlling the pesticide spraying device to spray the biological agents according to the established spraying paths, wherein according to the descending order of the path priorities, the pesticide spraying device is controlled to spray the biological agents along the spraying paths in sequence.

Description

technical field [0001] The embodiments of the present invention relate to the field of agriculture, and in particular to an automatic control method, a spraying device and a control system for biological agent spraying. Background technique [0002] In agricultural production, in order to prevent crops from being eroded by pests, crops are sprayed with biological agents, such as pesticides, at regular intervals. Among them, the broad definition of pesticides refers to the prevention, elimination or control of diseases, insects, grasses and other harmful organisms that endanger agriculture and forestry, as well as the purposeful regulation, control, and influence of plants and harmful organisms. Metabolism, growth, development, and reproductive processes A substance or a mixture of several substances and its preparations derived from chemical synthesis or derived from organisms, other natural products and applied biotechnology. In a narrow sense, it refers to a class of drug...

Problems solved by technology

[0003] However, the inventors have found that at least the following problems exist in the prior art: due to the absence of an automated and intelligent biological agent spraying mechanism in the prior art, targeted and accurate spraying of drugs is not possible, the effect of preventing and controlling pests and diseases is poor, and the cost is high. Drug contamination cannot be avoided
