Title:
REMOTE INTELLIGENT VARIABLE-RATE IRRIGATION APPARATUS FOR PHOTOVOLTAIC-DRIVEN TRANSLATIONAL SPRINKLER
Document Type and Number:
WIPO Patent Application WO/2023/173903
Kind Code:
A1
Abstract:
A remote intelligent variable-rate irrigation apparatus for a photovoltaic-driven translational sprinkler. The apparatus is composed of a translational sprinkler truss (1), a solar driving apparatus (2), a plant water deficit diagnosis apparatus (3), a variable-rate spraying flow measurement and control apparatus (4), and a remote intelligent irrigation control system (5). A photovoltaic driving system alternately provides power for travel driving and irrigation pressurization. When a sprinkler operates, water deficit information of crops is acquired in real time, an irrigation volume for the crops is calculated in real time, and precise rapid measurement and regulation and control over a spraying flow are achieved. The remote intelligent variable-rate irrigation apparatus combines decision information with device actions, such that unsupervised autonomous operation can be achieved; and the apparatus is incorporated into a cloud by means of an Internet-of-Things gateway, such that the apparatus can be remotely monitored and managed, and stable operation of the apparatus is ensured. The remote intelligent variable-rate irrigation apparatus for a photovoltaic-driven translational sprinkler achieves efficient utilization of optical energy, intelligent decision making, autonomous operation and stable operation.
