Establishment of Intelligent Integrated Fertilizer and Irrigation Management System Based on Internet of Things

目前的水肥一体化系统普遍存在监测参数少,形成的植物生长模型及混肥算法精准度较低,控制系统运算能力较弱且功能单一,不能实现智能控制等缺点。利用物联网构建无线传感器网络是水肥一体化系统的发展趋势。为提高农业生产上肥料与水资源的利用率,促进现代农业发展,通过采用视觉采集技术、无线传感器物联网监控技术和自动控制系统技术相结合,建成基于物联网,利用机器视觉测量植物生长参数,无线传感器物联网监测环境和土壤参数,以植物生长模型和模糊神经网络算法形成精准水肥混合方案,以ARM11嵌入式系统为核心的农作物智能水肥一体化管理系统。

The current integrated fertilizer and irrigation system is deficient in less monitoring parameters,low accuracy of formed plant growth model and mixed fertilizer algorithm,weak operational capacity and single function of control system,and non-realization of intelligent control.Wireless sensor network based on Internet of Things is the development trend of integreated fertilizer and irrigation system.In order to enhance the utilization rates of fertilizer and water in agricultural production,and promote modern agriculture development,through the combination of vision acquisition technology,wireless sensor Internet of Things monitoring technology and automatic control system technology,the authors built an intelligent integrated fertilizer and irrigation management system with the ARM11 embedded system as the core.In this system plant growth parameters were measured with machine vision,environment and soil parameters were monitored with wireless sensor Internet of Things,and accurate fertilizer and irrigation integration scheme was formed by plant growth model and fuzzy neural network algorithm.
