System and method for moving spans of an irrigation system

摘要

A method of moving at least two irrigation spans across a ground surface of a field may include receiving an initial movement control signal corresponding to a user-selected fluid application rate, determining the user-selected fluid application rate from the initial movement control signal, determining a position of at least one span in the field, modifying the initial movement control signal to a modified movement control signal according to a predetermined modification factor, with a value of the modification factor varying according to a position of the span in the field such that the modification factor varies among span positions, and sending the modified movement control signal to the drive motor control. A system is also disclosed.

1. A method of moving at least two irrigation spans across a ground surface of a field, at least one tower supporting the spans, the at least one tower having a wheel driven by a drive motor controlled by a drive motor control, the method implemented on a movement modification device comprising:
receiving an initial movement control signal corresponding to a user-selected fluid application rate indicating a rate of movement for the span; determining the user-selected fluid application rate from the initial movement control signal; determining a position of at least one span in the field; modifying the initial movement control signal to a modified movement control signal according to a predetermined modification factor, a value of the modification factor varying according to a position of the span in the field such that the modification factor varies among span positions; and sending the modified movement control signal to the drive motor control to thereby modify the rate of movement of the span.
