Field test of an automatic controller for solid-set sprinkler irrigation

摘要: The application of new technologies to the control and automation irrigation processes is becoming very important, automatic generation execution schedules receiving growing attention. In this paper, a prototype controller for solid-set systems presented. device composed by software hardware developments. was named Ador-Control it integrates five modules: first four modules simulate drop trajectories, water distri- bution, crop growth yield, last module ensures bidirectional communication between hard- ware. Decision variables based on soil, crop, performance indexes were used make real-time irriga- tion decisions. A randomized experimental design designed validate over corn during two seasons. Three treatments analyzed: T0) manual programmer or advanced farmer; T1) auto- matic scheduling controlled soil simulated content performance; T2) simu- lated thresholds indexes. Experi- mental results in 2009 2010 indicated that resulted similar maize yield but using less than (10 % T0 T1, 18 T2).
