Abstract: A mobile irrigation system including a number of spans, a number of mobile irrigation towers supporting the spans, and a control system. The control system includes a position switch configured to be triggered and transmit a trigger signal and a controller configured to receive the trigger signal from the position switch. Upon receiving the trigger signal, the controller is configured to determine whether a current position of the mobile irrigation system equates to an auto-reverse position. If the current position equates to the auto-reverse position, the controller is configured to transmit a reverse direction signal to a drive motor of one of the mobile irrigation towers to reverse direction so that the drive motor reverses direction.

Abstract: An alignment control system for controlling an alignment of a plurality of mobile towers, each mobile tower supporting a section of conduit in an irrigation system comprises a plurality of tower angle measurement devices and a control processing element. Each tower angle measurement device is associated with a successive one of the mobile towers and is configured to measure an angle value which varies according to a rotation angle of the associated mobile tower relative to one or more of the other mobile towers. The control processing element is configured or programmed to receive the angle value from each tower angle measurement device, compare the angle value to a threshold angle value, and generate and transmit control signals, data, or both that include an activation hysteresis value to a drive motor associated with each mobile tower that has an angle value greater than the threshold angle value.

Abstract: An irrigation control panel, an irrigation system, and a method of monitoring operations of the irrigation system are provided. The irrigation control panel comprises a display and a processing element. The display comprises an electrophoretic portion. The processing element is configured to determine an operating condition of the irrigation system, and display an indication representative of the operating condition on the electrophoretic portion so that the indication representative of the operating condition displayed on the electrophoretic portion persists after disconnecting power.

Abstract: A tilt monitoring system for a mobile irrigation system including a sensor and a controller. The sensor is configured to detect a tilt magnitude of the span and generate a corresponding tilt signal. The controller is configured to receive the tilt signal representing the tilt magnitude, generate a deactivation signal representing an instruction to deactivate the drive motor if the tilt magnitude is greater than a tilt threshold, transmit the deactivation signal to the drive motor, generate a notification signal representing a notification that the drive motor has been deactivated due to the tilt magnitude, transmit the notification signal, receive a follow-up input signal representing a follow-up input, generate a follow-up command signal representing a command for implementing the follow-up input, and transmit the follow-up command signal so that the mobile irrigation system implements the follow-up input.

Abstract: A smart irrigation system including a mechanized irrigation machine having a main machine controller, a plurality of distributed controllers, and a communications network. The distributed controllers may be located at a plurality of spaced apart locations on the mechanized irrigation machine. The communications network may communicably couple the plurality of distributed controllers, the main machine controller, and local or remote cloud storage. Furthermore, the main machine controller and the plurality of distributed controllers may retrieve or store information from the local or remote cloud storage for maintenance, firmware updates, or troubleshooting of the mechanized irrigation machine. The distributed controllers may perform the following functions: individual tower motor control, span joint control, corner arm control, GPS guidance or positioning of one or more actuatable features of the smart irrigation system, and/or valve control of individual sprinklers for variable rate irrigation.

Abstract: An irrigation system comprises a plurality of towers, a time domain reflectometry (TDR) unit, and a central controller. Each tower includes a successive one of a plurality of safety switches, with each safety switch being either closed or open. The safety switch of each tower is electrically connected to at least one safety switch of another tower. The TDR unit is electrically connected to at least one safety switch and is configured to output data regarding an open safety switch. The central controller is configured to receive data from the TDR unit, and determine, according to the data from the TDR unit, at least one of a location of the open safety switch and an identifier of the tower associated with the open safety switch.

Abstract: A control system for use with an irrigation system that includes a plurality of towers comprises a plurality of node controllers and a main controller. Each node controller is associated with a successive one of the towers and is configured to monitor operation of a plurality of components of the tower and to transmit data that includes a node identification number which corresponds to a positional number of the associated tower. The main controller is configured to receive the data. The control system executes a configuration process in which each node controller is assigned the node identification number in a sequence.
