Automatic irrigation system

Abstract

The invention relates to an automatic irrigation system, which comprises a main control device, multiple irrigation pipelines, an electromagnetic valve device, a sensor device and a wireless communication device, wherein the sensor device is arranged on a piece of land requiring irrigation; a water pump is arranged on each irrigation pipeline, and is positioned at one end close to a water source; a pressure gauge is arranged in each irrigation pipeline, and is positioned at one end close to an irrigation sprayer; the pressure gauges are connected with the main control device; the main control device controls the water pumps to open or close as per high and low water pressure values from the pressure gauges; the main control device is in wireless communication with a control mobile phone and the internet. The automatic irrigation system has the benefits as follows: the system can be controlled manually or automatically, and a more accurate effect can be obtained through combination of the two control manners; the manner that one water pressure control device is matched with one irrigation pipeline is adopted, so that the energy is saved on one hand, and the impact on the pipelines by high water pressure can be reduced and the pipelines are protected on the other hand.

Description

technical field [0001] The invention relates to the field of agricultural irrigation, in particular to an automatic irrigation system. Background technique [0002] With the development of modern agriculture and horticultural industry, large-scale planted crops or horticultural crops must rely on automatic irrigation systems to complete irrigation operations. Existing irrigation systems are divided into traditional irrigation and automatic irrigation. The traditional irrigation system is actually semi-automatic. It is opened and closed by manually opening and closing the valve. Its defects are obvious, time-consuming, laborious and inefficient; The automatic irrigation system is divided into a timing irrigation system and a timely irrigation system. The advantage of the timing irrigation system is that it is more efficient, but because it does not actively detect the humidity of the irrigated land, the probability of mis-irrigation is high, so it is easy to cause waste of wa...

Existing irrigation systems are divided into traditional irrigation and automatic irrigation. The traditional irrigation system is actually semi-automatic. It is opened and closed by manually opening and closing the valve. Its defects are obvious, time-consuming, laborious and inefficient; The automatic irrigation system is divided into a timing irrigation system and a timely irrigation system. The advantage of the timing irrigation system is that it is more efficient, but because it does not actively detect the humidity of the irrigated land, the probability of mis-irrigation is high, so it is easy to cause waste of water; timely The sensor used in the irrigation system detects the parameters of the irrigated land, and the main control system automatically selects the irrigation times and time according to the detected parameters. The judgment method is relatively simple, but at the same time, there is often a certain error between the judgment result of a single parameter and the actual soil condition, and the probability of mis-irrigation is high. If multiple parameters are used as the judgment standard at the same time, for example, an automatic The fertilizer and water irrigation system with control function provides nearly ten parameters. How to combine and automatically judge so many parameters to obtain the actual situation close to the irrigated land is also a difficult problem

[0003] A common defect of all the above-mentioned automatic irrigation systems is that they cannot effectively detect mis-irrigation and waste caused by pipe ruptures in practical applications.

resulting in large economic losses for growers
