An irrigation and fertilization system based on cloud computing technology

Abstract

The invention discloses an irrigation and fertilization system based on cloud computing technology, which includes a data collection module, a data analysis module, a controller, a signal execution module, a dose analysis module, a dose collection module, a dosing action module, a concentration collection module and Signal indicating module; the present invention firstly generates each signal according to the plant growth information before spraying and fertilizing, and controls the work of spraying and fertilizing equipment accordingly, so as to adjust to a suitable spraying and fertilizing position and spraying and fertilizing amount, so as to achieve the purpose of improving the effect of spraying and fertilizing At the same time, the amount of spraying fertilizer and the remaining amount of medicine will be analyzed together with the weather temperature to determine whether to add the medicine, and the concentration change caused by the weather and temperature in the dosing liquid storage tank will be compared with the concentration of the plant at this time. Combined with growth information to reasonably control the amount of chemicals and water added, so that the growth rate and nutrient ratio of each plant are more balanced.

Description

technical field [0001] The invention relates to the technical field of fertigation systems, in particular to a fertigation system based on cloud computing technology. Background technique [0002] The process of fertilizer entering the field with irrigation water is called fertigation, that is, while drip irrigation or subsurface drip irrigation, fertilizer is applied to plants according to the nutrient needs and climatic conditions of each stage of plant growth. And fertigation can be roughly divided into three categories: surface irrigation, underground irrigation and injection irrigation. [0003] And in the document whose publication number is CN108934366A, it is only based on the meteorological sensing device to detect the rainfall information, and the controller controls the opening of the automatic door to collect rainwater. At the same time, the controller also controls the opening of the irrigation solenoid valve and the fertilization solenoid valve according to the...

Problems solved by technology

[0003] And in the document whose publication number is CN108934366A, it is only based on the meteorological sensing device to detect the rainfall information, and the controller controls the opening of the automatic door to collect rainwater. At the same time, the controller also controls the opening of the irrigation solenoid valve and the fertilization solenoid valve according to the soil moisture condition. Timely irrigation and fertilization of the soil to be irrigated; and combining it with the existing fertigation system, it is still difficult to adjust the location and amount of fertilization according to the growth of the plants before spraying and fertilization, so as to improve the spraying rate. Fertilization effect; and it is difficult to consider the impact of fertilization amount and drug residue and drug volatilization caused by weather factors together, and combine the plant growth status and drug concentration at this time to rationally add drugs and water, so that each plant The growth rate and nutrient ratio are more balanced
