Variable fertilization control system and method

Abstract

The invention relates to the field of an automatic control system. The invention uses a variable fertilization control system which comprises a singlechip used for receiving external storage information, input information, feedback information and communication information and outputting control information and display information after internal arithmetic processing, and the control information is the control towards the fertilizer quantity of a fertilizing machine. The singlechip is connected with an electro-hydraulic proportional valve by a converter. An input end of the electro-hydraulic proportional valve is connected with the converter, and an output end is connected with a hydraulic motor. The output end of the hydraulic motor is connected with a fertilizing shaft of the fertilizing machine. One end of the fertilizing shaft is equipped with a photo-electricity coder, an electrical signal of which is fed back to the singlechip. The singlechip is also connected with an adjustment knob circuit. The electro-hydraulic proportional valve and the adjustment knob circuit are controlled by the singlechip and are used for adjusting the fertilizer quantity of the fertilizing shaft of the fertilizing machine. The integral manual and automatic variable fertilization control system has high practical value, simple structure and convenient operation.

Description

technical field [0001] The invention relates to the field of automatic control systems, in particular to a variable fertilization controller that integrates manual and automatic design, can automatically receive or manually input the amount of fertilization, and utilizes a closed-loop control algorithm in a single-chip microcomputer to accurately realize the output of control signals. Background technique [0002] Precision agriculture is one of the hot fields of agricultural science research in the world in recent years. The meaning of precision agriculture is to finely and accurately adjust various soil and crop management measures according to the specific conditions of each operating unit in the field, and to maximize the optimization of various agricultural inputs in order to obtain the highest yield and maximum economic benefits, while protecting the agricultural ecological environment , Protect land and other agricultural natural resources. Precision agriculture is a...

Problems solved by technology

[0009] The current variable fertilization controllers are often some independent control modules, or communicate with other modules through serial ports, which have poor scalability and cannot form a complete system

[0010] The variable fertilization controller in our country is still in its infancy. At present, it mainly relies on the introduction of foreign technology for digestion and absorption, and the imported equipment is expensive, complex in structure and difficult to operate.
