All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides an intelligent irrigation system based on water and fertilizer integration, where the system includes:
the data acquisition unit is used for acquiring detection data and meteorological data; wherein the detection data includes crop data, soil data, and environmental data.
Specifically, the crop data includes a variety of crops and respective growth cycles of the crops; wherein each growth cycle corresponds to a growth condition;
the soil data comprises soil type, soil entropy, soil nutrient data and water storage capacity of soil;
the environment data comprises wind direction, wind speed, temperature and humidity, illumination and air pressure data;
the above data are merely examples, and are not intended to be limiting.
A control unit for:
sending the detection data into a pre-formed strategy model for processing to obtain a corresponding control plan; wherein the strategy model is obtained by training by using a neural network algorithm;
and correcting the control plan by using the meteorological data to obtain a corresponding irrigation plan.
Specifically, the neural network algorithm may employ a pre-stored expert knowledge base as a training set and a validation set; when the system is applied, the data acquired by the data acquisition unit is used as input, and data such as soil entropy condition, soil nutrients, water and fertilizer irrigation amount and the like are used as output to form a corresponding control plan;
meanwhile, meteorological data related to irrigation are considered, so that the influence of extreme meteorology in the later period is avoided; for example, the irrigation amount of water in the control plan needs 600L, but the meteorological data shows that the subsequent rainfall has an equivalent irrigation amount of 200L, and the subsequent rainfall is combined and correlated to avoid waste of water resources and avoid the growth influence on crops caused by excessive water amount.
The irrigation unit is used for driving the execution equipment to act according to the irrigation plan so as to carry out intelligent irrigation; wherein, the execution equipment comprises water and fertilizer integrated equipment and irrigation equipment.
Specifically, when the irrigation system is applied, the irrigation plan comprises specific irrigation data, a soil entropy index, an equipment control command and the like; the irrigation unit adopts an intermittent working mode when executing the irrigation plan; therefore, water and fertilizer can be fully combined with soil, and then the control unit updates the corresponding irrigation plan according to the periodic feedback data of the data acquisition unit, so that irrigation is more accurate.
Further, when the irrigation system is implemented, the irrigation plan comprises water and fertilizer integrated irrigation and a subsequent clear water washing plan; that is, after the irrigation is completed, the pipeline is flushed for a certain time so as to be ready for the next irrigation, and the irrigation accuracy is improved by taking the irrigation amount generated by the cleaning into consideration.
The method is used for reducing the precipitation of substances in the water manure, the blockage of pipelines and the interference between the water manure of different crops after the water manure is irrigated so as to ensure safe and effective fertilization.
From the above description, it can be seen that, in the implementation of the water and fertilizer integration-based intelligent irrigation system provided by the embodiment of the present invention, the acquired crop data, soil data and environment data are sent to a pre-formed strategic model to be processed to obtain a control plan, and the control plan is corrected in combination with meteorological data to obtain a corresponding irrigation plan, so that the irrigation plan is obtained depending on various factors and is associated with the meteorological data, thereby improving the intelligence and accuracy of the scheme, and overcoming the defects of few considered influencing factors and poor intelligence in the prior art.
In another embodiment, on the basis of the scheme, in order to comprehensively consider the correlation influence of different factors, the control plan is corrected by using the meteorological data, the soil type and the water storage capacity of the soil to obtain a corresponding irrigation plan; for example, soil can be classified into three types, sandy soil, clay soil, and loam soil. Wherein:
sandy soil: coarse-grained soil refers to soil with a large content of particles larger than 0.1 mm, and can be classified into gravel soil and sand soil. Its advantages are high sand content, coarse grains, high water seeping speed, high water-retaining performance and high air permeability.
Clay soil: it features high water-holding performance, low sand content, fine particles, low water seepage speed, high water-holding performance and poor air permeability.
Loam: the soil is characterized in that the content of clay, powder and sand in the soil particles is moderate, and the particle size is between 0.2mm and 0.02 mm. The texture is between clay and sandy soil, and has the advantages of both clay and sandy soil. Its advantages are high sand content, general grains, water seepage speed, water retention and ventilation.
