This invention discloses an
intelligent decision-making
system for precise water allocation in
agricultural irrigation districts based on
crop water requirement coefficients. The
system comprises three main modules: hardware acquisition and execution,
software algorithms and modeling, and digital twin
simulation and decision-making. These modules operate in a closed-loop logic of acquisition,
processing,
simulation, decision-making, execution, and feedback. The hardware module employs a four-dimensional collaborative acquisition, dual-mode transmission, and
edge computing scheme. The
software module incorporates algorithms and
adaptation rules such as dual-factor
coupling and dynamic
water requirement coefficient correction. The digital twin module completes instruction issuance and parameter correction through full-
element modeling, LOD optimization, and multi-objective decision-making. This invention, through dual-path feedback, digital twin
collaboration, and multi-
algorithm coordination, combined with dynamic
water requirement coefficient correction, terraced field spatial
adaptation, and
soil water-salt
coupling modeling, accurately matches plot requirements, balancing
water conservation,
crop adaptation, and
energy consumption, thereby reducing
irrigation district management costs and adapting to complex
irrigation district operations.
