Automatic variable pesticide spraying system and control method thereof

Abstract

The invention discloses an automatic variable pesticide spraying system and a control method thereof. The automatic variable pesticide spraying system comprises a moving trolley, a pesticide box and a variable frequency pump, wherein the pesticide box and the variable frequency pump are mounted on the moving trolley. The pesticide box is connected with an inlet of the variable frequency pump through a pesticide conveying pipeline, an outlet of the variable frequency pump is connected with N pesticide conveying branch pipes through a pesticide conveying main pipe, and a shower nozzle is mounted at the end of each pesticide conveying branch pipe. Liquid pesticide output by the variable frequency pump can be further conveyed back into the pesticide box through a return pipe, the return pipe is provided with a first flow valve, and a flow sensor and a pressure sensor are further arranged on the pesticide conveying main pipe between the return pipe and each pesticide conveying branch pipe. A second flow valve is arranged on each pesticide conveying branch pipe. The automatic variable pesticide spraying system and the control method thereof have the obvious advantages that a variable pesticide application technology can be used for spraying pesticide as required according to acquired small-area difference information of farmland injurious insects, the pesticide spraying amount can be controlled accurately, pesticide waste can be avoided, the environment can be prevented from being polluted, and the system is even in pesticide spraying and good in atomization effect.

Description

technical field [0001] The invention relates to the technical field of precision agriculture, in particular to an automatic variable spraying system and a control method thereof. Background technique [0002] In our country, agriculture has always been the foundation of national economy, national self-reliance and social stability. People's vital interests and social stability are always affected by agricultural development. In recent years, precision agriculture has become a hot topic in the field of international agriculture. The definition of precision agriculture is: at the micro level, according to the specific conditions of each field operation unit, finely and accurately adjust various management measures of soil and crops, optimize various agricultural inputs to the greatest extent, and protect the natural ecological environment and land. Under the premise of using natural resources and so on, in order to obtain the maximum economic, ecological and environmental ben...

Problems solved by technology

However, my country has not yet realized the precise and variable spraying machinery. The traditional spraying method is to treat the crops on a whole piece of land as objects with the same degree of pests and diseases for spraying.

The uniform spraying of crops can prevent and control pests, but it is easy to cause waste of pesticides, pollute the environment, and is not conducive to ecological development
