A kind of greenhouse micro-spray irrigation facility based on environmental information and its control method

Abstract

The invention provides a greenhouse micro-spray irrigation facility based on environmental information and a control method thereof. The facility includes an outdoor monitoring system for measuring total irradiation amount; an indoor monitoring system for measuring soil humidity and air temperature; an automatic film roller ; A micro-sprinkler irrigation system for irrigation and a control module for receiving the measured value output by the outdoor monitoring system and the indoor monitoring system and controlling the automatic film roll and the micro-spray irrigation system according to the measured value. The control method provided by the present invention utilizes the measured environmental information, adopts a control module to compare and analyze whether the temperature and soil moisture meet the preset value when the total irradiation amount reaches a predetermined value, thereby controlling the operation of the irrigation system and realizing the facility production. Precision irrigation and automated irrigation save a lot of labor and improve production efficiency. At the same time, because of the linkage method of micro-spray irrigation and electric film roll, the influence of wind on micro-spray irrigation is reduced.

Description

technical field [0001] The invention belongs to the field of agricultural irrigation, and relates to a micro-spray irrigation facility and a control method thereof, in particular to a greenhouse micro-spray irrigation facility based on environmental information and a control method thereof. Background technique [0002] Plastic greenhouses, commonly known as cold sheds, are a type of facility commonly used in facility agriculture. The skeleton of the plastic greenhouse is made of galvanized pipe, aluminum alloy pipe or steel pipe and other materials to form an arched shed, and the skeleton is covered with a plastic film. Plastic greenhouses are often used for the cultivation of vegetables, flowers and fruits, which enables the supply of these agricultural products to be earlier or delayed, while increasing the yield per unit area, which is more conducive to preventing natural disasters. Plastic greenhouses can be divided into single greenhouses and multi-story greenhouses. ...

AI Technical Summary

Problems solved by technology

In the production of normal greenhouse facilities, it generally takes 5-10 minutes to complete the irrigation of a greenhouse. When there are many plastic greenhouses that need to be irrigated, it takes a lot of manpower

Moreover, judging whether to irrigate and controlling the irrigation time mainly depends on the user's experience, so it is difficult to achieve precise irrigation
