Embodiment Construction

[0054] A simple water and fertilizer integrated automatic control fertilizer injection system for orchards, which includes an Arduino-based data acquisition subsystem, a Raspberry Pi-based control system, and an App remote control unit.

[0055] Based on the Raspberry Pi control system, it is connected with the Arduino data acquisition subsystem and the pump respectively, and communicates with the App remote control unit. The user inputs the standard water and fertilizer ratio parameters through key input or App remote control. The standard water-to-fertilizer ratio, the water speed and fertilizer speed fed back by the Arduino data acquisition system are used to adjust the fertilizer absorption rate of the pump and control the water-to-fertilizer ratio.

[0056] The Arduino data acquisition subsystem includes a microcontroller Arduino and a Hall flow sensor. The Arduino collects water speed and fertilizer speed data through the Hall flow sensor, and transmits the data to the pr...

Abstract

The invention discloses a simple water and fertilizer integrated automatically controlled fertilizer injection system and a fertilizer injection control method for an orchard. The system comprises anArduino-based data acquisition subsystem, a Raspberry-pi-based control system and an App remote control unit, wherein the Raspberry-pi-based control system can automatically complete a soil pre-wetting time control task, a water and fertilizer mixing ratio regulation and control and fertilizer injection time control task and a pipeline flushing time control task according to the acquired data. Thewhole system and method have the characteristics of simplicity and easiness in operation, high fertilizer pumping precision and accurate water and fertilizer ratio regulation and control; and the system is good in performance stability and high in safety.

Description

technical field [0001] The invention relates to an orchard agricultural automation equipment, in particular to a simple water and fertilizer integrated automatic control fertilizer injection system and method for an orchard. Background technique [0002] The traditional way of fertilizing orchards is usually to spread the fertilizer manually, and then flood the orchard fruit trees through ditches to achieve the effect of fertilizing the orchard. However, the traditional fertilization methods cannot be scientifically and rationally fertilized according to the actual needs of fruit trees and soil conditions, which may easily cause imbalance and lack of nutrient elements in the orchard soil, and may also easily cause water and fertilizer waste and soil pollution. Aiming at the problems existing in traditional orchard fertilization methods, this system designs a simple water and fertilizer integration automatic fertilizer injection machine equipment for orchards combined with wa...
