Intelligent irrigation control system and method

Abstract

The invention discloses an intelligent irrigation control system which comprises an information acquisition module, a control module, a judgement module, an irrigation module and a fertilizer applyingmodule. The information acquisition module is used for acquiring soil related information, the control module is used for receiving the soil related information acquired by the information acquisition module and processing the soil related information; the judgement module is used for sending the soil related information which is processed and sent by the control module, comparing the processed soil related information with the preset threshold and generating control signal according to comparison result; the irrigation module is used for supplying water and supplying manure fertilizer or chemical fertilizer to soil or plant planted in the soil; the fertilizer applying module is used for adding manure or chemical fertilizer to the irrigation module. The intelligent irrigation control system can realize precise applying of fertilizer and full stirring of the fertilizer, without excessive fertilizer adding, can recover residual water to prevent plant or crop from being withered due to waterlogging, and is good for growth of plant or crop.

Description

Technical field [0001] The invention relates to the field of agricultural irrigation, in particular to an intelligent irrigation control system and method. Background technique [0002] my country is a country with severe drought and severe water shortage. Freshwater resources account for only 6% of the world. The dwindling water resources have made people realize the importance of water conservation. Among them, agricultural water accounts for as much as 80% of my country's total water volume, so how to save agricultural water has become the focus of my country's water conservation work. [0003] Since the greatest potential of agricultural water saving in our country lies in the field, at present, surface irrigation methods such as border irrigation, furrow irrigation, and flood irrigation are usually used. Although simple and easy to implement, this irrigation method takes a long time to irrigate and easily causes waste of water resources. It is easy to form compaction, and the...

Problems solved by technology

[0003] Since the greatest potential for my country's agricultural water saving lies in the field, at present, surface irrigation such as border irrigation, furrow irrigation, flood irrigation and other irrigation methods are usually used. It is easy to form compaction, and the water content of the surface soil is too high, which makes the soil permeability poor and the crop root system has difficulty breathing

In addition, people need to go to the site to observe the soil-related conditions and the growth of crops, and use experience to decide whether irrigation, fertilization, and pesticides are needed. With the development of smart agriculture, irrigation equipment in agricultural activities has also been changed to irrigation and fertilization control systems. However, The existing irrigation and fertigation control systems are not intelligent enough. Most of them are artificially mixing fertilizer and water to mix the two fully. The disadvantage is that the pesticide or fertilizer is not discharged according to the area of ​​the crops, which makes the crops not easy to absorb. unfavorable for the growth of crops
