Development And Implementation Of Intelligent Agriculture System Based On Internet Of Things Technology

Traditional agricultural models have inherent shortcomings such as delayed dynamic feedback and large errors in control accuracy,which have severely affected my country’s agricultural modernization and wisdom in multiple dimensions such as energy consumption and benefits.Therefore,it is of great significance to carry out research on modern agricultural monitoring equipment with Internet of Things technology as the carrier.However,due to the complex environment in the greenhouse and the mutual influence of temperature,humidity and light intensity in the greenhouse,there is a certain coupling relationship,and the establishment of the control model is more complicated.Therefore,in order to ensure the stable operation and precise control of smart greenhouses,this paper introduces fuzzy control theory to provide a theoretical basis for the realization of smart agriculture by the Internet of Things technology.Greenhouses are a key part of my country’s agriculture,and its efficient development is critical to the national economy and people’s livelihood.Therefore,this article follows the smart development concept of replacing traditional manpower with remote monitoring,grasps the main environmental factors of crop growth through field research and access to data,selects the corresponding sensors reasonably,and fully analyzes the simplicity of operation requirements and cost factors.The development and design plan of smart agricultural system based on Internet of Things technology.For the greenhouse where plants grow out of season,the design and realization of the environmental data in the greenhouse are transmitted to the touch screen client through the RS485 communication protocol,and the switch of the exhaust fan in the greenhouse is directly controlled through the PLC and the touch screen integrated machine.At the same time,temperature and humidity sensors are used to collect environmental data of crops in the greenhouse.On the one hand,use the serial port module to transmit and collect environmental data and couple it through fuzzy control to achieve the optimal effect of plant growth.On the other hand,use the communication module to transmit the control commands sent by the touch screen to the PLC module,and then through PLC controls and monitors the status of various equipment in the greenhouse,and realizes the refined and systematic control of the greenhouse environment.This paper verifies the effectiveness and feasibility of the proposed strategy by building a smart agricultural monitoring system platform based on the Internet of Things technology and using Zig Bee communication technology to develop wireless sensors and mobile terminal applications.The experimental results show that compared with the traditional control scheme,the control strategy proposed in this paper can monitor the environmental factors in the shed in real time,and couple the collected environmental factors.It has the advantages of fast response speed,strong anti-interference ability,and high control accuracy.Users benefit from multiple perspectives such as output and labor cost input,and at the same time can achieve the optimal effect of plant growth,meet the intelligent control requirements of greenhouses,and facilitate engineering practice.
