The Applied Research Of The Internet Of Things Technology In The Greenhouse

People have higher demands for the quantity and quality of fruits and vegetables with the improvement of the living standard in our country.Greenhouse planting has still been a major way for agricultural production in our country,which was popularized in as early as the early 80 s in last century,but the backward mode of production and management has become the main factor restricting the further development.Therefore,it is urgent to achieve more scientific and efficient greenhouse production and management.In this situation,the concept of agricultural Internet of Things application will be an more important way to solve the greenhouse problems.Farms are the principal parts of greenhouse management.Their main demands,which were gained by field trip,data research and questionnaire analysis,for the greenhouse management system are that the system should collect the data of soil temperature and humidity,range of concentrations of carbon dioxide,the system should be automated on the basis of crop growth law,and the system transformation should have low costs and easy to operate,which can save manpower and material resources.Taking good advantage of agricultural Internet of Things Technology,a low cost and efficient monitoring and control system for greenhouse is designed,which Adopts a low cost,low power consumption and convenient data transmission of wireless transmitting module CC2530 Zigbee as an Intermediate data transmission control module,and its communication mode is mainly peer-to-peer and point-to-multipoint with Transmission reliability and Simple network.Samsung 4412 core board,which operates a simple and built-in WIFI function,serves as an embedded gateway.After evaluating,once the system is widely used in agricultural production,it will greatly reduce production cost and improve the quantity and quality of agricultural products.The overview: First,this paper introduces the background of the application technology of greenhouse.Second,it describes the technology,equipment and system of agricultural Internet of Things.Third,it elaborates the greenhouse detective and control system composed of data acquisition terminal,server and automatic control.The data acquisition part mainly collects the parameters which is transmitted to the embedded gateway via wireless network.Based on the above data,the server provides accurate and reliable basis for production and management.Operators can connect the server at any time and understand the parameters.To realize the production process automation,the automatic control system can be connected to the greenhouse heating system,sprinkler irrigation system and the canopy control system.Forth,it sets up an Internet greenhouse experiment platform and conducts experiments.The experimental results show that the design of the system is reasonable,with a network stability,accurate data collection and accurate management system.The design goal of the greenhouse iot system will be realized.
