基于物联网的地埋式渗灌水肥施用系统控制方法及装置
By using an IoT-based underground seepage irrigation and fertilization system, a dynamic control model is constructed using soil conductivity, moisture content, and pressure parameters. This solves the problem of slow salt migration detection in traditional underground water and fertilizer regulation schemes, and enables efficient water and fertilizer application and soil improvement in saline-alkali land.

Abstract
本发明提供一种基于物联网的地埋式渗灌水肥施用系统控制方法及装置，涉及地埋式水肥渗灌技术领域，本发明采集各控制区域的初始土壤电导率、含水率、管路压差与主管压力，依据压力偏离程度确定压力权重；由初始土壤电导率与耐盐阈值之差构建基础盐害项，经由含水率确定的非线性因子增益后得到盐水耦合状态量；利用管路压差构建压力反馈项，结合盐水耦合状态量修正基础渗流系数，经压力权重加权并与基础通量叠加生成压盐微水通量；依据压盐微水通量占比及主管压力引发的超压惩罚项计算淡水交替占空比，并据此驱动阀门执行动作。本发明实现了针对盐碱环境的按需给水与高效压盐，大幅提升了水肥配施的精准度。
