Novel photovoltaic computer controlled automatic micro-irrigation system

Abstract

The invention relates to a novel photovoltaic computer controlled automatic micro-irrigation system which comprises a power supply subsystem, an irrigation subsystem, a main controller and a data acquisition unit, wherein the data acquisition unit is used for monitoring environment parameters. The irrigation subsystem comprises a water pump, a reservoir, an irrigation pipeline, an energy-storage water tower and a flow path change-over valve. The water pump pumps water from the reservoir and is communicated with the energy-storage water tower and the irrigation pipeline through the flow path change-over valve, and a water outlet port of the energy-storage water tower is communicated with the irrigation pipeline through a stop valve. A water lever sensor is arranged inside the energy-storage water tower, the main controller is electrically connected with the water level sensor and is used for testing the water level signal of the energy-storage water tower, and the main controller judges whether the water pump is driven to add water in the energy-storage water tower to converse surplus solar energy to water potential energy. According to the novel photovoltaic computer controlled automatic micro-irrigation system, solar energy is used as power, intelligent and automatic water-saving irrigation is achieveed according to the growth cycle of plants, blindness of timing irrigation is avoided, and the effects of energy conservation and emission reduction are good.

Description

technical field [0001] The invention belongs to the fields of agriculture and garden irrigation, in particular to a photovoltaic computer automatic micro-irrigation system, which can be used for automatic irrigation of crops and flowers. Background technique [0002] At present, there are three main forms of water-saving irrigation methods at home and abroad: sprinkler irrigation, micro-irrigation (drip irrigation, micro-sprinkler irrigation, small tube outflow irrigation and infiltration irrigation), and walking water-saving irrigation. In these irrigation methods, most of them need to manually switch the water valve, or control it by timing method, which is easy to cause untimely watering and damage plants, and excessive watering will cause a lot of waste of water resources. For cash crops, foreign countries have adopted microcomputer-controlled greenhouse planting methods, including water delivery, fertilizer delivery, temperature control, and dry and wet control.
