Intelligent greenhouse irrigation system

Abstract

The invention relates to an intelligent greenhouse irrigation system. The intelligent greenhouse irrigation system includes a central control module, a data acquisition module, a data analysis module, an execution module, and a monitoring module; the data acquisition module includes a soil constituent detection module, a soil water content module, a soil pH module, a soil saline and alkaline module, and a greenhouse temperature and humidity module; the data analysis module includes a soil analysis module and a greenhouse temperature and humidity analysis module; the execution module includes an irrigation module, a greenhouse climate regulation module, and a water drain module; and the irrigation module includes a water supply module, a water storage module, a water quality purification module, a water source supply module, a water pressure regulation module, a pipe irrigation module, a spraying irrigation module and a drop irrigation module. Through the improvement, the intelligent greenhouse irrigation system can intelligently acquire and analyze soil information and greenhouse environment information and can perform intelligent automatic timing irrigation; the manual power and the water source can be saved, irrigation is scientific, and the irrigation efficiency can be improved; and the intelligent greenhouse irrigation system has safety and is easy to use.

Description

technical field [0001] The invention relates to the field of greenhouse plant irrigation, in particular to an intelligent greenhouse irrigation system. Background technique [0002] my country is a country with severe drought and water shortage. my country's total fresh water resources are 2.8 trillion cubic meters, accounting for 6% of global water resources, ranking fourth in the world after Brazil, Russia and Canada. However, my country's per capita water resources are only 2,300 cubic meters, only 1 / 4 of the world's average level, and it is one of the countries with the poorest per capita water resources in the world. However, China is the country with the largest water consumption in the world. In 2002 alone, the country’s fresh water intake reached 549.7 billion cubic meters, accounting for about 13% of the world’s annual intake, which is about 1.2 times that of the US’s 470 billion cubic meters of fresh water supply in 1995. my country is also a large agricultural c...

In 2002 alone, the country’s fresh water intake reached 549.7 billion cubic meters, accounting for about 13% of the world’s annual intake, which is about 1.2 times that of the US’s 470 billion cubic meters of fresh water supply in 1995. my country is also a large agricultural country, and agricultural irrigation is It plays a pivotal role in agricultural production. At present, many areas in my country still use traditional border irrigation, furrow irrigation, submerged irrigation and flood irrigation for agricultural irrigation. Although this irrigation method can play the role of irrigation, there is serious waste of water and easy Lead to water level drop, land salinization and other problems
