Problems solved by technology

[0002] In recent years, small unmanned aerial vehicles have been widely used in agricultural production activities such as spraying chemical pesticides and liquid fertilizers due to their maneuverability, flexibility, and high control precision. , short battery life, etc.
For example, CN201811031041.1 patent application document discloses a "Unmanned Aircraft Intelligent Spraying System and Method Based on Prescription Map". The manned aircraft survey system can realize the precise operation of unmanned aircraft, but it still has problems such as small load, serious fog droplet drift, and short battery life.
Conventional ground spraying machines, such as boom sprayers, have the advantages of wide spray width, long battery life, high operating efficiency, large payload, uniform spraying, and less droplet drift, but the "carpet" spraying mode adopted , quantitative application of pesticides per mu of land, uniform spraying, resulting in a large amount of waste of pesticides, but also a greater threat to the safety of the ecological environment

Abstract

The invention discloses a selective spraying system suitable for a ground spraying machine. A flexible spraying rod capable of being rolled and stretched is used for applying pesticides to weed partsin a targeted mode, the pesticide consumption can be reduced, pollution to the surrounding environment or damage to crop health can be avoided, drip leakage can be effectively prevented, pesticide waste can be reduced, and the operation quality can be improved. The invention discloses a cooperative pesticide application system and a cooperative method. The aerial survey capability of an unmanned aerial vehicle is utilized for farmland information sampling and establishing crop spatio-temporal spectral data, an onboard industrial personal computer is used for inverting the health condition of the crop, and information such as position coordinates, disease types and grades of health abnormal areas is sent to the ground spraying machine, so that the unmanned aerial vehicle and the ground spraying machine can collect and share information in a unified environment model, the advantages of wide spraying width, long endurance time and high operation efficiency of the ground spraying machine are utilized, the unmanned aerial vehicle and the ground spraying machine can carry out operation at the same time, the operation efficiency is greatly improved, and the use amount of pesticides / chemical fertilizers is reduced.
