Control method and system of intelligent irrigation

Abstract

The invention relates to a control method and system of intelligent irrigation. The method comprises the steps as follows: environmental parameters of an irrigation area are collected by a meteorological station and transmitted to a cloud server; the cloud server calculates water requirement of crops according to the environmental parameters and determines the walking speed of a sprinkling machineaccording to the water requirement of crops; the cloud server sends a walking speed instruction of the sprinkling machine to a centralized control station; the centralized control station receives the walking speed instruction of the sprinkling machine, starts the sprinkling machine and sends a water pump start instruction to a pump station; the pump station receives the water pump start instruction, starts a water pump and opens a hydraulic control valve, so that precise irrigation with self-adaptive capacity for weather and terrain is realized, agricultural condition acquisition and intelligent irrigation are combined scientifically and effectively, different irrigation schemes are formulated according to different irrigation requirements of crops and different geographical environments, the irrigation precision and resource utilization rate are increased, the labor cost is reduced, and the method can save 15% of water or above as compared with traditional irrigation manners.

Description

technical field [0001] The invention relates to the field of remote irrigation control, in particular to an intelligent irrigation control method and system. Background technique [0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry. The science that studies agriculture is agronomy. The labor objects of agriculture are living animals and plants, and the products obtained are animals and plants. Agriculture provides the basic products that support the construction and development of the national economy. In the cultivation of agricultural crops, it is necessary to irrigate the crops to promote the growth of the crops and replenish the water needed for the growth of the crops. The traditional irrigation methods are mostly based on the experience of farmers in the field, and even flood irrigation, which is time-consuming and laborious. Th...

In the cultivation of agricultural crops, it is necessary to irrigate the crops to promote the growth of the crops and replenish the water needed for the growth of the crops. The traditional irrigation methods are mostly based on the experience of the farmers in the field, or even flood irrigation, which is time-consuming and laborious. The pertinence is poor, and precise irrigation cannot be carried out according to the water demand of the crops, which will easily lead to the leaching of inorganic nitrogen in the plant and layer, and increase the loss of crop nutrients, thereby greatly increasing the incidence of plant disease and restricting growth, which will bring damage to plants and soil. immeasurable loss
