Problems solved by technology

However, these potentiometer or encoder based sensors are mechanically connected to the span rope and are therefore subject to wear over time
Additionally, the potentiometers typically require initial setting by specially trained personnel and may be sensitive to temperature fluctuations or other environmental variables

Abstract

A center-pivot irrigation system having a plurality of towers interconnected by a plurality of spans actuatable about a center pivot, a plurality of solid-state sensors each mounted in fixed alignment with one of the spans or towers, and a control system communicably coupled with the solid-state sensors. The solid-state sensors may send acceleration, angular acceleration, angular rotation, heading, and/or angle measurements to the control system, which may use these measurements to calculate alignment of the spans relative to each other and/or the center pivot and to calculate locations of the spans or towers using a known location of the center pivot. The solid-state sensors may be solid-state gyroscopes, solid-state accelerometers, digital compass, and/or an inertial measurement unit (IMU).

Description

technical field [0001] The present invention relates to a system and method for use in the field of irrigation. Background technique [0002] Irrigation systems are often used to deposit water and / or pesticides in crop fields. Irrigation systems may consist of multiple spans that are connected together and move across a field on frame blocks; or "pylons" with wheels. Center pivot irrigation systems can move in a circle or semicircle around a central pivot, while lateral movement irrigation systems can move in a generally straight line over a generally square or rectangular field. [0003] Some center-pivot irrigation systems use potentiometers and / or encoder-based sensors attached to the span rope or tower via adjustable mechanical linkages to determine pitch, span alignment, and positioning in the field. However, these potentiometer or encoder based sensors are mechanically connected to the span rope and are therefore subject to wear over time. Furthermore, the potentiom...
