Fertilization control system for round translation sprinkling machine

Abstract

The invention discloses a fertilization control system for a round translation sprinkling machine. The fertilization control system comprises a device body and a control system, wherein the device body is provided with a sprinkler irrigation tube, a distance sensor, universal wheels, a base plate, a fertilizer tank installation opening and a fertilizer tank; the control system is arranged in the device body and is provided with a master control system, a remote control module, a speed measurement sensor, an information collection module, a storage module, an intelligent control module, a circuit control system, a fertilization control system, a water pressure control unit, a drive module, a power supply module, a frequency conversion module, a distance sensing module, a fertilization pump, a pressure sensor, a servo motor and a liquid level sensor. The fertilization control system is reasonable in design and uniform in fertilization, is capable of performing automatic fertilization, is capable of automatically and accurately adjusting the sprinkling distance of fertilizer through the fertilization pump, and is simple in operation; and accurate and constant fertilization concentration and fertilization amount are ensured.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a fertilization control system for circular and translation sprinkler irrigation machines. Background technique [0002] The fertilization control system currently used in agriculture generally includes a fertilizer container for storing liquid fertilizer, and an irrigation pipe for transporting the liquid fertilizer in the fertilizer container to the farmland for fertilization. The irrigation pipe is provided with an on-off valve. According to their own practical experience, agricultural personnel purchase fertilizers and make liquid fertilizers and store them in fertilizer containers, and then fertilize by manually operating the on-off valve according to the fertilization method summarized by experience. Among them, the fertilization method refers to the specific fertilization time and fertilization amount. Factors to be considered are: fertilizing a certain crop wi...

Problems solved by technology

When the tail gun of the circular sprinkler or the corner arm system is periodically opened and closed in the corner area, the pressure of the pipe outlet changes and when the sprinkler encounters roads, rivers, buildings and other fields during walking Obstacles, when it is necessary to close some nozzles, the inflow flow of the sprinkler irrigation machine changes, but the fertilizer injection flow rate of the fertilizer injection pump remains constant, which will lead to uneven concentration of the sprayed fertilizer solution, and a decrease in the uniformity of the overall fertilizer solution spraying, affecting crop growth and yield

The existing circular and translational sprinkler irrigation machines and the technical equipment for realizing the integration of water and fertilizer are generally based on simple coupling of equipment, consisting of fertilizer tanks / fertilizer ponds, agitators, fertilizer injection pumps and supporting pipelines, without precise calculation and control devices. Only realize the generation, injection and extensive fertilization of fertilizer solution
