Farmland water-saving irrigation system with remote control function on basis of solar energy technology

Abstract

The invention discloses a farmland water-saving irrigation system with a remote control function on basis of a solar energy technology. The system comprises a photovoltaic component, an electric energy storage device, a water pump and a water storage tank, wherein the photovoltaic component is electrically connected with a header box; the header box is electrically connected with a direct-current cabinet; the direct-current cabinet is electrically connected with a controller; the controller is connected with the electric energy storage device and an inverter; the inverter is electrically connected with the water pump and a water level sensor; a water inlet end of the water pump is connected with a water feeding pipe; a signal receiver is arranged at the top part of the water storage tank; the water storage tank is connected with a drip irrigation device through a duct; the drip irrigation device comprises a plurality of drip irrigation pipes and a plurality of drippers; the drip irrigation pipes are communicated with the duct; the drippers are arranged on the drip irrigation pipes. The system disclosed by the invention has the advantages that water can be automatically supplemented to the water storage tank, so that a large amount of time is saved; a user can send an instruction to the controller through a remote terminal for irrigating plants according to an actual weather condition, so that not only is convenience brought to the user, but also the water resources are greatly saved by adoption of a drip irrigation manner.

Description

technical field [0001] The invention relates to the technical field of application of photovoltaic power generation systems, in particular to a farmland water-saving irrigation system that can be remotely controlled based on solar energy technology. Background technique [0002] Water-saving irrigation is an irrigation measure to obtain the maximum yield or profit with the minimum amount of water, that is, to maximize the crop yield and output value per unit of irrigation water. At present, the main measures of water-saving irrigation in various countries in the world include channel anti-seepage, low-pressure pipe irrigation, sprinkler irrigation, micro-irrigation, etc. After the water-saving irrigation project is implemented, the labor allocation in the irrigation process can be reduced. Drip irrigation can be used for local moist irrigation, the field soil is loose, and the air permeability is good. Soluble fertilizers, plant growth regulators, systemic insecticides, etc....

AI Technical Summary

Problems solved by technology

[0003] However, most traditional water-saving irrigation systems use mains electricity to drive water pumps for pumping operations. This not only requires the installation of circuits, which consumes a lot of electricity, but also consumes a lot of water resources by flood irrigation, making it difficult to achieve the purpose of water saving.

In the prior art, although there is an irrigation method that uses solar power generation for sprinkler irrigation, the water consumption of sprinkler irrigation is still very large, which requires a large amount of electric energy to supply water pumps for pumping operations, resulting in users having to invest a lot of money to buy more photovoltaics. components, making the system unfavorable for popularization; in addition, the traditional solar power irrigation system cannot realize remote control, and users need to spend a lot of time to operate the irrigation site. Once the distribution of the irrigation system is too scattered, it will be difficult to manage.
