Agricultural automatic-variable fertilizer applicator control system

Abstract

The invention relates to an agricultural automatic-variable fertilizer applicator control system, and belongs to the technical field of agricultural engineering. The agricultural automatic-variable fertilizer applicator control system is mainly composed of a GIS decision support system, an IC card, a central processing chip, a GPS module, a rotation speed acquisition module and a stepping motor controller. The agricultural automatic-variable fertilizer applicator control system in the invention can perform automatic-variable fertilizer application when judging an operation unit, where a fertilizer applicator is, by receiving a GPS position signal, and control the rotation speed of a fertilizer discharging shaft on the fertilizer applicator by monitoring the advancing speed of the fertilizer applicator and reading the fertilizer application amount stored on the IC card.

Description

technical field [0001] The invention relates to an agricultural automatic variable-variable fertilizer control system, which belongs to the technical field of agricultural engineering. Background technique [0002] In my country, the application of chemical fertilizers, especially nitrogen fertilizers, has problems such as low utilization rate and environmental pollution. In order to solve these problems, precise variable fertilization must be carried out. There are many achievements and progress in the research of variable fertilization control system at home and abroad. Although foreign molding systems have excellent performance, their overall cost is very expensive, and the climate and soil conditions on which they are based are not quite the same as those in our country, so they are not suitable for promotion in our country. However, the variable fertilization system studied in China has the disadvantages of complex mechanical mechanism, great influence on the physical...

Problems solved by technology

Although foreign molding systems have excellent performance, their overall cost is very expensive, and the climate and soil conditions they are based on are not quite the same as those in my country, so they are not suitable for promotion in my country.

However, the variable fertilization system studied in China has the disadvantages of complex mechanical mechanism, greatly affected by the physical characteristics of fertilizers, and high cost.
