Title
(EN) SYSTEM AND METHOD FOR ADJUSTING IRRIGATION SYSTEM SCHEDULING
(FR) SYSTÈME ET PROCÉDÉ POUR LE RÉGLAGE DE PLANIFICATION DE SYSTÈME D'IRRIGATION
Abstract
(EN)
An irrigation system and method of controlling operations of the irrigation system are provided. The method includes determining, via a control system, a soil water depletion at a first location based on soil data captured via a sensor; determining, via the control system, a difference in irrigation amounts at the first location and a second location; determining, via the control system, a difference in precipitation amounts at the first location and the second location; determining, via the control system, a difference in evapotranspiration values of crops at the first location and the second location; calculating an estimated soil water depletion at the second location based, at least in part, on the soil water depletion at the first location, the difference in irrigation amounts at the first location and the second location, the difference in precipitation amounts at the first location and the second location, and the difference in evapotranspiration values of crops at the first location and the second location; and directing, via the control system, the irrigation system to apply an amount of water at the second location based, at least in part, on the estimated soil water depletion at the second location. The irrigation system may comprise a fluid-carrying conduit, a plurality of support towers with one or more controllable motors, water emitters, a controllable valve, and a control system that performs one or more of the aforementioned method steps.

L'invention concerne un système d'irrigation et un procédé de commande d'opérations du système d'irrigation. Le procédé consiste à déterminer, par l'intermédiaire d'un système de commande, un épuisement d'eau de sol à un premier emplacement sur la base de données de sol capturées par l'intermédiaire d'un capteur ; à déterminer, par l'intermédiaire du système de commande, une différence de quantités d'irrigation au premier emplacement et à un second emplacement ; à déterminer, par l'intermédiaire du système de commande, une différence de quantités de précipitations au premier emplacement et au second emplacement ; à déterminer, par l'intermédiaire du système de commande, une différence de valeurs d'évapotranspiration de cultures au premier emplacement et au second emplacement ; à calculer un épuisement d'eau de sol estimé au second emplacement sur la base, au moins en partie, de l'épuisement d'eau de sol au premier emplacement, de la différence de quantités d'irrigation au premier emplacement et au second emplacement, de la différence de quantités de précipitation au premier emplacement et au second emplacement et de la différence de valeurs d'évapotranspiration de cultures au premier emplacement et au second emplacement ; et à diriger, par l'intermédiaire du système de commande, le système d'irrigation pour appliquer une quantité d'eau au second emplacement sur la base, au moins en partie, de l'épuisement d'eau de sol estimé au second emplacement. Le système d'irrigation peut comprendre un conduit de transport de fluide, une pluralité de tours de support avec un ou plusieurs moteurs pouvant être commandés, des émetteurs d'eau, une vanne pouvant être commandée, et un système de commande qui effectue une ou plusieurs des étapes de procédé mentionnées ci-dessus.
