Abstract

The invention provides a variable irrigation control method, device and system based on a large sprinkler. The method includes the steps that configuration information input by a user is sent to a constant-pressure water supply unit, a geographical point monitoring unit and a nozzle array control unit and / or a pump valve control unit, and therefore the units can set their running parameters according to the configuration information input by the user; geographical point information sent by the geographical point monitoring unit is received, and land parcel partitions of a current irrigation area are determined according to the geographical point information and current running parameters of the sprinkler; the running parameters of the sprinkler are adjusted according to preset configuration information corresponding to the land parcel partitions, and the preset configuration information corresponding to the land parcel partitions is sent to the nozzle array control unit so that the nozzle array control unit can adjust its running parameters according to the preset configuration information. By means of the method, the partitions can be recognized, the number of nozzles for work is adjusted or the water spraying amount is changed, partition irrigation is performed, and variable irrigation saving water and energy and reducing runoff and leakage is achieved.

Description

technical field [0001] The invention relates to the technical field of precision agriculture, in particular to a variable irrigation control method, device and system based on a large sprinkler irrigation machine. Background technique [0002] Variable irrigation is an important content and core component of the theoretical research and practice of precision agriculture. With its "high yield, high quality, high efficiency" modern agricultural production mode and technical system, it has become a hot field of sustainable agricultural development today. [0003] Sprinkler irrigation is currently one of the most widely used and fastest-growing high-efficiency water-saving irrigation technologies, saving 30% to 50% of water compared with flood irrigation. In recent years, my country's large-scale and intensive agricultural production has been accelerating, and large-scale sprinkler irrigation machines have been rapidly promoted and applied due to their advantages such as strong ...
