An intelligent irrigation system and its control method

Abstract

The invention discloses an intelligent irrigation system and a control method thereof, comprising a controller, a meteorological data acquisition module, an environmental information sensor and a water irrigation module. The detected environmental information, as well as the current meteorological data, set the duration of water stress, and control the opening or closing of the water irrigation module according to the duration of water stress, so as to realize intelligent irrigation. The controller uses a Raspberry Pi embedded computer, according to the real-time detection of soil temperature and humidity, combined with rainfall rate and water stress duration as input information. And input the above information into the adaptive expert decision-making module to control the switching state of the solenoid valve to realize intelligent irrigation. Users can also use the remote terminal to detect real-time soil temperature and humidity and control the irrigation module through the cloud platform, which has extremely high reliability and real-time performance, effectively improves the convenience and accuracy of irrigation, and reduces production costs.

Description

technical field [0001] The invention relates to the field of irrigation, in particular to an intelligent irrigation system and a control method thereof. Background technique [0002] Crop irrigation technology is an important support for national food. my country's agricultural irrigation water consumption accounts for about 60% of the total water. The overall efficiency of agricultural irrigation is relatively low, and waste is still common. [0003] The current irrigation system is mainly based on manual control, timed irrigation, or irrigation only by detecting soil moisture. Manual irrigation is troublesome and requires a certain amount of labor costs, while regular irrigation or irrigation when the soil moisture is insufficient has certain limitations, and there are still other factors such as wasting water resources, excessive or insufficient irrigation, and not being able to adapt to the environment (such as changes in soil moisture, rainfall). Contents of the inve...
