Greenhouse micro-spraying irrigation facility based on environmental information and control method thereof

Abstract

The invention provides a greenhouse micro-spraying irrigation facility based on environmental information and a control method thereof. The facility comprises an outdoor monitoring system used for measuring the total irradiation amount, an indoor monitoring system used for measuring soil humidity and air temperature, an automatic film rolling device, a micro-spraying irrigation system used for irrigation, and a control module used for receiving measured values output by the outdoor monitoring system and the indoor monitoring system and controlling the automatic film rolling device and the micro-spraying irrigation system to work according to the measured values. According to the control method provided by the invention, the measured environment information is utilized, the control module is adopted to compare, analyze and judge whether the temperature and the soil humidity meet the preset values or not when the total irradiation amount reaches the preset values, so that the irrigationsystem is controlled to work, accurate irrigation and automatic irrigation of facility production are achieved, a large amount of labor force is saved, and the production efficiency is improved. Meanwhile, due to the fact that the method of linkage of micro-spraying irrigation and the electric film rolling device is adopted, the influence of wind on micro-spraying 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 and a control method based on environmental information. 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 materials such as galvanized pipes, aluminum alloy pipes or steel pipes to form an arched shed, and the skeleton is covered with a plastic film. Plastic greenhouses are often used to cultivate vegetables, flowers and fruits, so that these agricultural products can be supplied earlier or later, and at the same time increase the output per unit area, which is more conducive to the defense against natural disasters. Plastic greenhouses can be divided into single-span greenhouses and multi-span greenhouses. It...

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
