Fecha de publicación: 17/06/2015 Fuente: Wipo "precision agriculture" The utility model discloses a precise agriculture control system of utilizing distributed control for automatic fertilization and water supply. The system comprises a plurality of field subsystems, an irrigation execution subsystem and an upper-level monitoring subsystem. The field subsystems are connected with the irrigation execution subsystem through a communication bus and send irrigation demands to the irrigation execution subsystem. The field subsystems are connected with the upper-level monitoring subsystem through the communication bus for transmitting working states of the field subsystems. Each field subsystem is mainly composed of a field control computer, and a temperature sensor, a shallow soil humidity sensor, a deep soil humidity sensor, an ion concentration sensor and a weather station which are connected with the field control computer. The irrigation execution subsystem is composed of an irrigation control computer, and a water pump, filtration equipment, a fertilizer applicator and a flow monitoring device which are connected with the irrigation control computer. The irrigation execution subsystem carries out quantitative watering or fertilization according to a demand after receiving the irrigation demand sent by a filed irrigation subsystem. The precise agriculture control system is high in flexibility, operational reliability and working efficiency.
