Abstract

La présente invention concerne un système de commande d'irrigation intelligent, un appareil d'irrigation et un procédé de commande correspondant. Le système de commande d'irrigation intelligent comprend : un module d'acquisition de données (201), un module de réception de données (202), un module de traitement central (203), un module de gestion d'appareil d'irrigation (204), un module d'exécution de terminal d'appareil d'irrigation (205), et un module de données de rétroaction (206). Le module d'acquisition de données (201) est utilisé pour acquérir et envoyer des données associées au module de réception de données (202). Le module de réception de données (202) envoie les données reçues au module de traitement central (203) afin de les traiter et de former une requête d'irrigation. Le module de traitement central (203) envoie la demande d'irrigation au module de gestion d'appareil d'irrigation (204). L'appareil d'irrigation élabore une instruction d'irrigation, et envoie l'instruction d'irrigation au module d'exécution de terminal d'appareil d'irrigation (205). Le module d'exécution de terminal d'appareil d'irrigation (205) commande à l'appareil d'irrigation correspondant d'exécuter une opération correspondante. Le module de données de rétroaction (206) envoie une rétroaction des données d'exécution de terminal d'appareil d'irrigation au module d'acquisition de données (201). L'invention permet de commander l'irrigation automatique intégrée d'eau, d'engrais et de pesticide, ce qui permet d'éliminer la nécessité d'ouvrir des vannes manuellement, et d'économiser du temps et du travail.
