Problems solved by technology

Although there are many cases of photovoltaic greenhouses, most of them simply install photovoltaic modules on the top of the greenhouse. Either transparent photovoltaic modules are used, and the power generation efficiency is not high, or the photovoltaic power generation and plant lighting cannot be effectively balanced.
In addition, my country's greenhouses generally have a low degree of automation and cannot achieve online monitoring and self-regulation. Not only can they not provide the best production environment for plants, but also waste energy.

Abstract

The invention discloses an energy self-supplying type intelligent greenhouse control system. The system comprises a data acquisition unit composed of an illuminometer, a temperature sensor, an air humidity sensor, a soil humidity sensor, an air pressure sensor and a soil fertilizer tester, a central control unit and a functional module composed of a solar cell panel, an LED (Light Emitting Diode) light supplementing system, a ground source heat pump, a water curtain, a fan, a water pump and a fertilizing device. The solar cell panel is mounted at the top of a greenhouse, is in a foldable structure and is used for providing a power supply to the central control unit and other functional modules. The invention further discloses an energy self-supplying type intelligent greenhouse control method. Solar photovoltaic power generation is used for providing electric energy to greenhouse power consumption equipment, and parameters including temperatures, humidity, light illumination, soil fertilizers and the like in the greenhouse are monitored online and intelligent adjusted, so that crops are in the optimal growth environment all the time, and the aims of high yield, high efficiency and energy conservation and environment friendliness are realized.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a control system and method for an energy self-sufficient intelligent greenhouse. Background technique [0002] At present, with the rapid development of greenhouses in my country, there are also extremely prominent problems, and the energy consumption of greenhouse production remains high. Although there are many cases of photovoltaic greenhouses, most of them simply install photovoltaic modules on the top of the greenhouse. Either transparent photovoltaic modules are used, and the power generation efficiency is not high, or the photovoltaic power generation and plant lighting cannot be effectively balanced. In addition, my country's greenhouses generally have a low degree of automation and cannot achieve online monitoring and self-regulation. Not only can they not provide the best production environment for plants, but also waste energy. Contents of the invention ...
