Single-chip-microcomputer-based intelligent control system and control method of plant culturing box

Abstract

The invention relates to a control system for a plant culturing box, particularly to a single-chip-microcomputer-based intelligent control system and control method of a plant culturing box. The control system is composed of a detection module, an environmental control module, a memory module and an input output module, wherein the detection module, the environmental control module, the memory module and the input output module are connected with a single-chip microcomputer module. The environmental control module is used for controlling the temperature, humidity, light intensity and CO2 concentration inside a plant culturing box. The control system and control method have advantages of convenience is operation, complete functions, high efficiency, energy conservation, and high extensibility; and intelligent simulation and control of parameters like the illumination, temperature, humidity and CO2 concentration and other parameters in a greenhouse environment can be realized. The temperature and humidity control systems used a PID control mode; the maximum absolute error of temperatures is 1 DEG C and the maximum humidity relative error control is + / -5%; the constant temperature and humidity fields are realized; the light intensity and CO2 concentration can be controlled accurately; and the growth needs of plants can be met.

Description

technical field [0001] The invention relates to a control system of a plant cultivation box, in particular to an intelligent control system and a control method of a plant cultivation box based on a single-chip microcomputer. Background technique [0002] Plant tissue culture is an important node in the industrial chain of facility agriculture. Temperature, humidity, light, CO 2 It is the most important external condition affecting plant tissue culture. At present, the fluorescent light source used in plant tissue culture does not completely match the banded spectrum emitted by the plant's selective absorption spectrum. It is used to supplement light in plant tissue culture, which has poor pertinence, low light efficiency, large heat generation, and high energy consumption; The heating device is mainly based on electric heating, but the electric heating elements are mostly side-heating electric heating tubes and electric heating plates, which have the disadvantages of large...

Problems solved by technology

At present, the fluorescent light source used in plant tissue culture does not completely match the banded spectrum emitted by the plant's selective absorption spectrum. It is used to supplement light in plant tissue culture, which has poor pertinence, low light efficiency, large heat generation, and high energy consumption; The heating device is mainly based on electric heating, but the electric heating elements are mostly side-heating electric heating tubes and electric heating plates, which have disadvantages such as large thermal inertia, low conversion efficiency, and high energy storage.
