Abstract: A wheel track monitoring system for an irrigation system monitors the condition of a wheel track and alerts an operator and/or automatically takes corrective action when a wheel track develops ruts or other conditions that may adversely affect operation of the irrigation system. The wheel track monitoring system includes a wheel track condition sensor, a location sensor, and a processing system. The processing system receives and stores wheel track condition data and location data from the sensors as the irrigation system travels across a field and creates a log of wheel track condition data for multiple locations in the field. The processing system also analyzes the wheel track condition data to determine if the condition of the wheel track is unacceptable at any locations in the irrigated field and generates a corrective action signal if the condition is unacceptable.

Abstract: A fault notification system comprises a plurality of tower sensor units and a central processing element. Each tower sensor unit includes a tower safety sensor and a tower processing element. The tower safety sensor monitors a rotation angle of a mobile tower and output a signal that varies according to the rotation angle. The tower processing element is configured to receive the signal, compare a signal level of the signal with a range of signal levels indicating a normal rotation angle, and transmit a message that a fault has occurred and request that each drive motor shut down if the level of the signal is out of the range indicating a normal rotation angle. The central processing element is configured to receive the message from the tower processing element and transmit a signal to each tower processing element to output a signal to instruct each drive motor to shut down.

Abstract: A system and method for overriding an alignment circuit of an electric center pivot irrigation system. The system may include a local controller wired to the alignment circuit and a remote control wirelessly communicating with the local controller. The remote control may receive an alignment fault alert from the local controller indicating that the alignment circuit has switched to the open circuit configuration. Next, the remote control may send an auto-alignment signal to the local controller. The auto-alignment signal may instruct the local controller to command a relay to switch to a bypass mode. In the bypass mode, signals between the local controller and operational elements of the electric center pivot irrigation system bypass the alignment circuit. The auto-alignment circuit may also command the operational elements to reverse travel directions of the electric center pivot irrigation system simultaneously while the alignment circuit is bypassed.

Abstract: A control system for a low-volume irrigation system includes a plurality of valve controllers for opening and closing valves; an irrigation system controller for controlling the valve controllers in accordance with an irrigation plan; and a graphical user interface for allowing a user to interact with the irrigation controller and to create the irrigation plan. The graphical user interface displays an irrigation zone list, an irrigation set list, and an irrigation plan field. The user interface has drag and drop functionality that permits an irrigation zone listing from the irrigation zone list to be dragged and dropped into any of the irrigation set listings in the irrigation set list and that permits an irrigation zone listing or an irrigation set listing to be dragged and dropped into the irrigation plan to create irrigation steps within the irrigation plan.

Abstract: A system and method for retrofitting an electric center irrigation pivot to have a standardized user interface and remote control functionality. A local control element having a standardized local user interface is installed at a pivoting point of the pivot by bypassing an existing control logic of an original control system while using an existing transformer of the original control system. A remote control element having a standardized remote user interface is also installed at the pivoting point of the pivot, and is functionally integrated with the local control element. A position-determining element is mounted on a movable portion of the electric pivot. Retrofitting multiple pivots provides each with the same standardized user interfaces. Because existing elements of the original control system are either bypassed or used, uninstalling the system and reverting to the original control system can be quickly and easily accomplished.
