System and method of flow rate management and control within an irrigation corner assembly

Abstract

The present invention provides a system and method for irrigation management and, more particularly, to a system and method for managing and controlling flow rate within an irrigation corner assembly. According to a first preferred embodiment, the present invention teaches a method comprising the steps of: recording irrigation system and irrigation field data; performing a simulated pass around a field and executing a simulated irrigation plan along a selected guidance path; determining the current and maximum sprinkler areas for at least one corner sprinkler at selected points/increments along the selected guidance path; determining the current and maximum extension ratios for the selected sprinklers at the selected increments; calculating the duty cycle for each sprinkler at each selected increment along the corner guidance path based on the determined sprinkler areas and extension ratios; recording calculated duty cycles in a look-up table for each corner sprinkler at each referenced pivot angle; executing the irrigation plan; and setting the valve duty cycles for each corner sprinkler to the tabulated values at each referenced pivot angle.
