Novel Monitoring System for Detecting Malfunctioning In-Canopy Sprinklers on a Center Pivot Irrigation System

Abstract

The preservation of limited aquifer resources in the US Great Plains has driven the innovation and deployment of more efficient sprinkler packages for center pivot irrigation systems. One of the more efficient sprinkler packages available are in-canopy sprinkler packages, which hang low in the canopy. Although effective, they have the potential to become entangled in crop biomass and detach from the center pivot. Such detachments impact the efficiency and uniformity of the system, resulting in disrupted flow and pressure conditions, ultimately decreasing crop yield. Therefore, it is crucial that producers detect and replace missing in-canopy sprinklers immediately. A novel prototype monitoring system was designed using low-cost, publicly available technologies to monitor in-canopy sprinklers on a center pivot irrigation system and alert the user when and where an in-canopy sprinkler has become detached from the center pivot span. Later design revisions of the monitoring system introduced the ability of the monitoring system to also detect when a sprinkler became clogged. Experimental trials verified that the monitoring system operates efficiently and accurately; however, minor changes need to be made before large-scale implementation is possible.

Intelligent Control System for Monitoring the Maintenance of the Center Pivot Irrigation System

“…Agricultural output losses result from operating failures during crucial stages of crop growth, lack of qualified maintenance crew, and expensive maintenance procedures (Debauche Olivier et al, 2020;Aaron et al, 2021). Therefore, proper maintenance requires expert detection by expert system, speedy failure location discovery, decision making to stop machine movement, and manual problem-solving methods to prevent system and crop.…”
