Airborne variable pesticide application system and method for agricultural unmanned aerial vehicle

Abstract

The invention relates to the technical field of agricultural pesticide application, in particular to an airborne variable pesticide application system and method for an agricultural unmanned aerial vehicle. The airborne variable pesticide application system comprises the unmanned aerial vehicle, a prescription map aerial pesticide application system, a monitoring center, a GPS positioning mechanism and a meteorological station. The prescription map aerial pesticide application system is installed on the unmanned aerial vehicle and used for decision making of pesticide application prescriptions of the unmanned aerial vehicle. Decision making signals are sent to a lower computer through an upper computer, and the lower computer is used for carrying out online dynamic adjustment on the pesticide application mechanism of the unmanned aerial vehicle. The monitoring center is used for monitoring the work speed and the drifting condition of the unmanned aerial vehicle. The GPS positioning mechanism is used for positioning the geographic position of the GPS positioning mechanism. According to variable pesticide application, the system combines the advantages of equipment and decision making software to carry out prescription map generation and research on guiding variable work of pesticide application equipment, and use and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of agricultural pesticide application, in particular to an agricultural drone airborne variable pesticide application system and method. Background technique [0002] China is a large agricultural country, and its pesticide production technology has reached the international advanced level, but the current situation of pesticide use technology is seriously backward and its rapid development of pesticide level is extremely disproportionate. The irrational use of pesticides has caused a series of negative effects and has become a restrictive factor for the development of my country's agricultural economy. At present, the development of agricultural equipment such as drones is very rapid, and research on variable spraying is carried out through hardware innovations.

AI Technical Summary

Problems solved by technology

The irrational use of pesticides has caused a series of negative effects and has become a restrictive factor for the development of my country's agricultural economy.

At present, the development of agricultural equipment such as drones is very rapid. Research on variable spraying is carried out through hardware innovation, but the current airborne pesticide application system does not have the functions of field positioning and prescription map information execution. Sufficient information on pests and weeds is supported, which makes it impossible to achieve real precision drug use in the actual application process, and the control effect is not obvious or even inferior to traditional pesticide application methods; Although these research results have played an important guiding role in the actual application process and greatly improved the efficiency of drug use, but because their design and application are only limited to providing information to the operator, they have not participated in the actual application process. Therefore, the best control effect cannot be achieved

Moreover, there are very few studies on the instant automatic spraying system combining these two parts at present.
