System and method for controlling fertilization by intelligent amount changing

Abstract

The invention provides a system and a method for controlling fertilization by intelligent amount changing. In the fertilization control system, a submerged soil deep rotary tilling, stubble cleaning and filling integrating machine serves as a carrier, an ARM serves as a control core, and a global positioning system is combined with a plurality of sensors and controllers, precise amount changing fertilization of a fertilizer is realized, and layered selection of a seed fertilizer and a seedling fertilizer is also realized. The method comprises the following steps: before operation, adjusting a furrowing blade to select a fertilization depth, performing data processing on a fertilization prescription chart required by a plot, and writing in a USB (universal serial bus) memory card; during work, detecting fertilizer distributor positioning information, an equipment traveling speed state and motor feedback information in real time, controlling rotation speed of a fertilizer discharging shaft of a fertilizer distributor through a corresponding mathematical logic operation by the ARM, changing a fertilizer discharging amount of a fertilizer discharging machine, and distributing a fertilizer into a fertilization layer requiring the fertilizer; and archiving and storing a fertilizer distributing amount in an operation process for post analysis. The problems of uneasy control on fertilizer distributing and discharging amount, low utilization rate, waste, pollution and the like of the fertilizer are solved, and the aims of reducing investment, improving benefit and increasing yield of crops are realized.

Description

technical field [0001] The present invention relates to. The invention relates to agricultural automation and intelligence, in particular to an intelligent variable fertilization control system and control method for precision variable fertilization. Background technique [0002] "Precision agriculture" is a new trend in the development of agriculture in the world today. It is a system that implements a complete set of modern agricultural operation technology and management system in a fixed, fixed and quantitative manner based on spatial variation supported by information technology. Variable fertilization technology is an important part of precision agriculture. It is based on the actual needs of crops, based on scientific fertilization methods, and uses computers to guide fertilization and determine variable inputs to crops. To achieve the same income or higher income with the least or most economical input, improve the environment, efficiently use various agricultural r...

Problems solved by technology

Most of the high-efficiency variable fertilization controllers currently used at home and abroad are field computers, but due to high cost and large size, it not only increases the input cost, but also increases energy consumption. The relatively popular single-chip and PLC controllers have low efficiency and low function. Limited and unable to adapt to the market
