41 results about "Center pivot irrigation" patented technology

Center-pivot irrigation (sometimes called central pivot irrigation), also called water-wheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers. A circular area centered on the pivot is irrigated, often creating a circular pattern in crops when viewed from above (sometimes referred to as crop circles). Most center pivots were initially water-powered, however today most are propelled by electric motors.

GPS-based control system and method for controlling mechanized irrigation systems

A GPS-based control system for irrigation systems includes a power supply, a nonvolatile memory for storing a first set of coordinates corresponding to a reference position for the irrigation system, circuitry for receiving GPS data and using the data to generate a second set of coordinates corresponding to a current position of the irrigation system, and a microprocessor for calculating the azimuth and the distance between the reference position and the current position using the first and second sets of coordinates. The control system communicates with a main controller of the irrigation system to control a function of the irrigation system, such as stopping, reversing, end gun operation, application rate, or other auxiliary output, at a selected distance or azimuth value of the current position relative to the reference position. The control system can be used with either a center pivot irrigation system or a linear move irrigation system.

Swing arm guidance system

A guidance system for controlling the steering of a swing arm on a center pivot irrigation system is provided through the use of two satellite signal receiving antennas associated with a drive tower for the swing arm. The signal receiving antennas are mounted from the swing tower so that one of the antennas is in a position forwardly of a steerable wheel for the tower and the other antenna is located in a position rearwardly of the steerable wheel. The signal receiving antennas are mounted in such fashion that they rotate in a direct relation to the steering of the steerable wheel so as to provide position information for the steering of the drive tower that more efficiently and effectively maintains the drive tower on a desired path of travel.

Irrigation positioning system

A means of accurately determining the position of a selected location such as at the end of a center-pivot irrigation system by using two Global Positioning System (GPS) receivers. The first GPS receiver is located at a fixed, known position such as at the center of the pivoting irrigation system while the second GPS receiver is located on a moving portion of the irrigation system. The first GPS receiver compares the GPS receiver reported position against the actual position and reports by wire or radio link the position differences to the second GPS, where the differences are used to remove errors from the second receiver's measured position.

Center pivot irrigation system position sensing system

A system and method for determining a position of a center pivot irrigation system includes positioning a tower unit on the rotatable arm of the irrigation system, determining a distance between the arm's rotation center and the tower unit, calculating coordinates of the tower unit along a path of the tower unit as the arm rotates, and associating an action of the irrigation system with coordinates of the tower unit location that correspond to the position of the arm where the action is to occur. Optionally, the action of the irrigation system and the coordinates of the location of the tower unit are downloaded to a remote unit located adjacent to the irrigation system. Optionally, current location coordinates of the tower unit are determined using a GPS receiver at the tower unit. Optionally, the current location coordinates are transmitted from the tower unit to the remote unit. Optionally, the current location coordinates are compared to the coordinates of the location of the action. If a substantial match of the current location coordinates with the location coordinates associated with an action is detected, the action may be initiated by the remote unit through controls of the irrigation system.
