Automatic control system and method for variable pesticide spraying of unmanned aerial vehicle

Abstract

The invention provides an automatic control system for variable pesticide spraying of a rice unmanned aerial vehicle based on image processing. The automatic control system comprises a field information acquiring module, an information processing module, an information management decision-making module and an unmanned aerial vehicle variable spraying control module. The automatic control system and the automatic control method for variable pesticide spraying of the rice unmanned aerial vehicle based on image processing can set different dose prescription values according to disaster severity degrees of different plots so as to achieve better pest control effect, reduces agricultural cost and reduces dose. By combining the unmanned aerial vehicle pesticide spraying with a variable pesticide spraying technology, the pesticides are sprayed according to the practical damage condition changes of crops, so that the operation efficiency is improved, the dose of pesticides is reduced, the environmental pollution is relieved, the crop growth is facilitated, and the visual operation is realized by virtue of a real-time monitoring and display system.

Description

technical field [0001] The invention relates to an automatic control system for variable-variable pesticide application by an unmanned aerial vehicle for rice, belonging to the technical field of agricultural plant protection. Background technique [0002] Compared with traditional manual pesticide application in the field, drone spraying has high efficiency, less harm to operators, less labor and labor intensity, and can meet increasingly higher environmental protection requirements, achieving low-volume, high-precision pesticide application. Spray volume, less pollution, high efficiency, high control requirements. [0003] Agricultural drones have been used earlier in developed countries such as the United States and Japan, and play an important role in farmland monitoring and pesticide spraying. U.S. aerial spraying uses large fixed-wing agricultural aerial spraying equipment, which has poor flexibility and is not suitable for the characteristics of China's small agricul...

AI Technical Summary

Problems solved by technology

American aerial spraying uses large fixed-wing agricultural aerial spraying equipment, which has poor flexibility and is not suitable for the characteristics of small agricultural planting area, scattered land plots and complex terrain in China.

Domestic drone pesticide spraying has become an emerging field that has developed rapidly in recent years. Multi-rotor drones are mostly used, which have good maneuverability, but they all use uniform spraying methods, and it is impossible to set different levels according to the severity of disasters in different plots. Prescription value of drug dosage, so as to achieve better pest control effect, reduce agricultural costs, and reduce drug dosage
