Design and Implementation of Integrated Control System of Water and Fertilizer for Facilities Based on Cloud Platform

传统设施园艺生产过程中水资源的管理方式粗放,灌溉施肥方式落后、水肥资源浪费严重,不合理的施肥方式会造成土壤中残留肥料,对环境造成污染。为提高设施作物的水肥利用效率和作物产量,本研究围绕设施精准灌溉施肥技术研究基于云平台的设施水肥一体化控制系统。采用模块化的思想,设计了以STM32为控制终端的智能水肥一体化控制系统,实时采集水肥参数,利用灌溉施肥控制算法,实行闭环反馈控制,保证水肥溶液配制的精确性;采用触摸屏组态技术,设计了人机交互系统,拥有手动、定时定量、配肥等多种操作模式;利用物联网技术,设计了水肥一体化远程监控EMCP云平台,实现了云平台间的实时通信,满足了设施作业的网络化管理和智能化控制要求。

The management of crop water resources in the production process of traditional protected horticulture is extensive,the irrigation and fertilization methods are backward,and the water and fertilizer resources are wasted seriously.The unreasonable fertilization methods will cause residual fertilizer in the soil and cause pollution to the environment.In order to improve the water and fertilizer utilization efficiency and crop yield of facility crops,this research focuses on the integrated control system of water and fertilizer in facilities based on cloud platform around the technology of precision irrigation and fertilization in facilities.Using the idea of modularization,the intelligent water-fertilizer integrated control system with STM32 as the control terminal is designed to collect water and fertilizer parameters in real time,and implement closed-loop feedback control using irrigation and fertilizer control algorithm to ensure the accuracy of water and fertilizer solution preparation.The EMCP cloud platform for integrated remote monitoring of water and fertilizer is designed by using the Internet of Things technology.The real-time communication between cloud platforms is realized through ModBus protocol,and the network management and intelligent control of facility operation are realized.
