Intelligent pesticide spraying method and system for plant protection unmanned aerial vehicle

Abstract

The invention provides an intelligent pesticide spraying method and system for a plant protection unmanned aerial vehicle. By pesticide concentration sensors scattered on surfaces of crops in each farmland area, detection of farmland areas requiring pesticide spraying can be realized, and by the aid of a master PLC control unit and a first wireless transmitting unit, intelligent positioning of thefarmland areas requiring pesticide spraying is realized. By an image recognition unit, planting ranges and crop planting types in the farmland areas are determined, the own position of the plant protection unmanned aerial vehicle can be determined, a flight path covering the whole farmland areas in pesticide spraying can be generated by virtue of MCU, and accordingly pesticide spraying efficiencyis improved, and liquid pesticide waste is reduced. The unit spray amount and spray mist size of the plant protection unmanned aerial vehicle can be adjusted intelligently according to crop plantingtypes, real-time temperature and real-time illumination intensity, so that pesticides in reasonable quantity can be sprayed to the crops in each farmland, excessive volatilization of the pesticides iseffectively reduced, and integral quality of the crops in each farmland area can be effectively improved.

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.
