Intelligent irrigation system and control method thereof

Abstract

The invention discloses an intelligent irrigation system and a control method thereof. The intelligent irrigation system comprises a controller, a meteorological data acquisition module, an environmental information sensor and a water irrigation module, wherein the meteorological data acquisition module, the environmental information sensor and the controller are in data connection, the controllersets water-stress duration according to current environmental information detected in real time and current meteorological data, and according to the water-stress duration, turning on or off of the water irrigation module is controlled to achieve intelligent irrigation. The controller adopts a Raspberry Pi embedded computer, the soil temperature and humidity detected in real time, rainfall rate and the water-stress duration are taken as input information. The information is input into an adaptive expert decision module, and opening and closing states of a solenoid valve are controlled to achieve intelligent irrigation. A user further can utilize a remote terminal to detect the real-time temperature and humidity of soil through a cloud platform and control the irrigation module, the reliability and instantaneity are very high, and the convenience and accuracy of irrigation are effectively improved, and the production cost is reduced.

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 and rainfall).
