Greenhouse Remote Intelligent Control System Based On Cloud Service

In view of the shortcomings of the traditional greenhouse monitoring system in China in terms of terminal access and remote management,as well as the limitations in water-saving automatic control performance,this paper combines mobile technology and cloud server to study an embedded intelligence Control System.The system realizes intelligent control,real-time observation,remote control and user grading management of environmental factors in the greenhouse,which can not only improve irrigation and cultivation efficiency,but also promote the integration of agricultural planting,management and management processes,and promote the modern agricultural Internet of Things industry.development of.This system consists of three parts: on-site controller,cloud server and client.The main research work is as follows:First,the software and hardware development of the field controller side was completed.In terms of equipment hardware,the circuit design of the main controller module,power supply module,data acquisition module and 4G communication module based on STM32 is mainly carried out,and the optimal layout design of the data acquisition unit and irrigation pipe network is carried out;in terms of software Based on different functional units,the software design was carried out,and the fuzzy PID algorithm was studied for the soil irrigation control part.Secondly,the server design and deployment based on the Io T cloud platform have been completed.After a comparative analysis of the currently popular Io T cloud platform,the design plan for deploying the server on the Alibaba Cloud platform based on the MQTT communication protocol was determined.Then,from the aspects of data structure and API packaging,the construction design of device management service,data development service,business logic development service and rule engine data transfer service are introduced respectively.Then,the design and implementation of the Web client and mobile APP are completed.Among them,the Web client has designed subsystems according to different user levels,and can enter the page by scanning the QR code.Finally,the system was built at the experimental base,the server was deployed on the Alibaba Cloud platform,and on this basis,various system monitoring,network transmission,Web and mobile phone App operation and control functions were tested and analyzed,and the functions of each module were proved.And the feasibility of control strategies.
