Abstract

The invention provides a PLC-based solar energy automatic irrigation system and an irrigation method thereof. The PLC-based solar energy automatic irrigation system comprises a photovoltaic power supply module, a detection module, a PLC control module and an irrigation module, the irrigation system is controlled by the PLC control module, a fuzzy PID controller is adopted to control opening of an electromagnetic valve, the irrigation amount can be controlled more precisely, intellectualization of the irrigation system is greatly improved, and intelligent and water-saving irrigation is achieved. The tail end of a water-outlet valve is connected with a winch type irrigation machine, self-waking, self-stopping and self-adjustment of spray irrigation height can be achieved in the spray irrigation process, limitation of the geological environment is avoided, adaptability is high, and spray irrigation tasks in different environments can be completed. The photovoltaic power supply module is utilized to provide electricity for the irrigation system, the problem concerning energy required for irrigation in the irrigation area is solved, quite good energy-saving and emission-reducing effects are also achieved, and the ecological environment is protected.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to a PLC-based solar automatic irrigation system and an irrigation method thereof. Background technique [0002] At present, most of my country's farmland irrigation uses water pumps and other equipment for drainage and irrigation or sprinkler irrigation. In greenhouse cultivation of crops, uncontrolled drip irrigation is used. In the above irrigation methods, most of them need manual operation, or control the switch water valve by timing method, which may cause crop drought due to untimely watering, or excessive watering will cause a lot of waste of water resources. In addition, the power of the water pumps for agricultural irrigation is relatively large, and electric energy needs to be provided. Usually, the areas that need to be irrigated in the vast rural areas of our country are far away from the agricultural power grid, and special lines need to be built, or diesel power g...
