Control system and control method for automatic blending of pesticides

Abstract

The invention discloses a control system and a control method for automatic blending of pesticides. The control system comprises a microcontroller, a flow sensor set, a solenoid valve set, a stirringmechanism, a water pump, a pesticide pump and a man-machine interaction module; one flow sensor and one solenoid valve are arranged on a connecting pipe of a water tank and a pesticide mixing tank; one flow sensor and one solenoid valve are arranged on a liquor conveying pipeline of the pesticide mixing tank; each of the rest flow sensors and the solenoid valve corresponding to each flow sensor are arranged on the connecting pipe of the corresponding pesticide box and the pesticide mixing tank; the stirring mechanism is arranged on the pesticide mixing tank; the water pump is arranged on the connecting pipe of the water tank and the pesticide mixing tank; the pesticide pump is arranged on the liquor conveying pipeline of the pesticide mixing tank. The control system disclosed by the invention is capable of effectively and accurately controlling the dosage of pesticides and inflow volume of clean water in the pesticide mixing tank, accurately measuring dilution ratio and pesticide concentration and meanwhile effectively and accurately controlling the volume of pesticide inputted to the pesticide box of a pesticide device.

Description

technical field [0001] The invention relates to a control system, in particular to an automatic pesticide mixing control system and a control method, which can be used for automatic pesticide mixing during spraying operations of plant protection spraying equipment, and belongs to the field of pesticide mixing. Background technique [0002] At this stage, the prevention and control of diseases and insect pests in my country's agriculture and forestry mainly depends on the chemical control of pesticides, and most pesticide formulations need to be diluted with water and formulated to a certain concentration or multiple before use. dilution. At present, pesticides are mixed manually in plant protection operations. Due to uneven manual mixing, the mixing accuracy cannot be guaranteed, which will lead to large errors in the dilution of pesticides, waste pesticides, and affect the operation effect. Not only that, improper operation of manual mixing of pesticides will bring great po...

Problems solved by technology

At present, pesticides are mixed manually in plant protection operations. Due to uneven manual mixing, the mixing accuracy cannot be guaranteed, which will lead to large errors in the dilution of pesticides, waste pesticides, and affect the operation effect. Not only that, improper operation of manual mixing of pesticides will bring great pollution to the environment, and will also cause harm to the health of workers

[0003] Nowadays, the operation of plant protection drones is developing rapidly and widely. Some manufacturers have produced pesticide boxes, but the existing pesticide boxes can only be mixed manually, with single functions and low accuracy, which cannot meet the requirements of spraying equipment spraying operations.
