An intelligent agricultural irrigation system based on the Internet of Things

Abstract

The invention discloses an intelligent agricultural irrigation system based on the Internet of Things. The intelligent agricultural irrigation system comprises an environmental parameter detection module, a soil humidity detection module, a soil temperature detection module, an environmental data preprocessing module, a management database, an irrigation parameter analysis module, a management server, a display terminal and an irrigation control module. According to the intelligent agricultural irrigation system based on the Internet of Things, the temperature, humidity, carbon dioxide concentration, soil humidity and soil temperature in each acquisition time period in the greenhouse are acquired and processed; the irrigation proportionality coefficient of the soil in the greenhouse is analyzed, the amount of water required to be irrigated per square meter corresponding to each irrigation proportionality coefficient is extracted according to the irrigation proportionality coefficient of the soil; the irrigation amount corresponding to the area occupied by the greenhouse is obtained, the accuracy of the soil irrigation amount is improved, the water demand of the greenhouse can be reasonably analyzed according to the current environmental parameters in the greenhouse, the soil is prevented from being too dry or too wet, and the accurate control over the soil irrigation amount ineach time period is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation and relates to an intelligent agricultural irrigation system based on the Internet of Things. Background technique [0002] Agricultural irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation and micro-irrigation. Traditional surface irrigation includes border irrigation, furrow irrigation, flood irrigation and flood irrigation, but these irrigation methods often consume a lot of water and have low water utilization, which is an unreasonable agricultural irrigation method. Ordinary sprinkler irrigation technology is more common in agricultural production in China However, the water use efficiency of ordinary sprinkler irrigation technology is not high, and modern agricultural micro-irrigation technology includes micro-sprinkler irrigation, drip irrigation, infiltration irrigation, etc. These irrigation technologies generally ...

AI Technical Summary

Problems solved by technology

[0003] At present, the above-mentioned irrigation methods cannot be used to irrigate the crops in the greenhouse according to the amount of water required by the actual growth environment, resulting in too much or too little water for irrigation, and it is impossible to accurately control the amount of irrigation. The accuracy of the amount of irrigation is poor and cannot Provide the best irrigation amount for the crops in the greenhouse during each growth process, which affects the growth of the crops. At the same time, it is impossible to judge whether the carbon dioxide, temperature, humidity and other parameters in the greenhouse are in line with the growth of the crops. Once the concentration of carbon dioxide in the greenhouse is too high, photosynthesis is affected, the temperature is too high to increase the emission of water vapor, which makes the crops dry, and the humidity is too high to increase the diseases of the crops. Therefore, timely ventilation and heat dissipation in the greenhouse play an important role in the growth of crops, but At present, the cultivation personnel rely on their experience to ventilate and dissipate the greenhouses. It is impossible to comprehensively analyze whether the greenhouses need ventilation and heat dissipation according to the actual environmental conditions in the greenhouses. The timeliness of ventilation and heat dissipation is poor, and it is impossible to perform different levels of ventilation and heat dissipation on the greenhouses in time, resulting in crop damage. The output is reduced. In order to solve the above problems, an intelligent agricultural irrigation system based on the Internet of Things is now designed.
