Patent number: 10285343Abstract: A center pivot irrigation system is described that includes a controller that makes use of a particular flow rate of input water to deliver a consistent depth of irrigation to user-defined areas under a pivot irrigator. The controller operates to pulse control valves for the nozzles/sprinkler heads on and off as the sprinkler arm rotates. The valve pattern along the span of the sprinkler arm is chosen during each operating cycle such that the total water flow through all the open valves matches the flow rate of the input or supply water to the pivot irrigator. To ensure a consistent depth, the speed is changed during valve duty cycles to match the density of open valves in the sprinkler arm. To ensure a consistent distribution under the sprinkler arm, each valve is monitored to ensure that the valves are given the same proportional share of the input water.Type: GrantFiled: May 6, 2015Date of Patent: May 14, 2019Assignee: TRIMBLE INC.Inventor: Mark Jonathan Whalley
