An intelligent pesticide spraying method and system for plant protection drones

Abstract

The invention provides an intelligent pesticide spraying method and system for a plant protection drone. Through the pesticide concentration sensors scattered on the surface of the crops in each farmland area to detect which farmland areas need to spray pesticides, and then cooperate with the general PLC control unit and the first wireless sending unit to realize the intelligent positioning of the farmland areas that need to be sprayed with pesticides; through the image The identification unit is used to determine the planting range and crop types in the farmland area. At the same time, it can locate the plant protection drone's own position, and then cooperate with the MCU to generate a flight trajectory that can spray pesticides covering the entire farmland area, thereby improving the efficiency of pesticide application. Reduce the waste of liquid medicine; intelligently adjust the unit spraying amount and spray droplet size of the plant protection drone through the crop planting type, real-time temperature, and real-time light intensity, so that the crops in each farmland area can be sprayed with a reasonable amount of medicine, At the same time, it effectively reduces the excessive volatilization of pesticides, thereby effectively improving the overall quality of crops in each farmland area.

Description

technical field [0001] The invention relates to a system and method of a plant protection drone, in particular to an intelligent pesticide spraying method and system for a plant protection drone. Background technique [0002] At present, agricultural diseases, insect pests and weeds are restrictive factors affecting world food security and supply of agricultural products. The use of vector pesticides can effectively prevent and control crop pests and diseases, and can also effectively eliminate weeds to increase crop yields. However, the pesticide application machinery and technical level in most countries are relatively backward, which has caused the problems of low utilization rate of pesticides and excessive environmental pollution. [0003] With the rapid development of the drone industry, a large number of plant protection drones for spraying pesticides have been born. The plant protection UAV has the advantages of strong mobility, flexible control, low operating cost...

AI Technical Summary

Problems solved by technology

At present, in large-scale farmland areas, some crops have different local temperature and illuminance due to the influence of geographical location, and most of the current plant protection drones only rely on certain software algorithms to achieve coverage spraying in a certain area. In turn, this part of the crops is under-sprayed or over-sprayed, resulting in large deviations in crop yields in farmland areas.

At the same time, due to the distribution of farmland areas, covering spraying will cause a lot of waste, so it is necessary for plant protection drones to intelligently locate and spray the farmland areas that need to be sprayed to save resources.
