The Applied Research Of The Internet Of Things Technology In The Greenhouses Environment

The internet of things is a new technology, it is technology which are acombination of wireless sensors, RFID, computer network and embedded system, andwidely used in many fields, such as mine surveying, underground monitoring, etc. theThe internet of things has obtained a good application effect, brought better benefits.The application of the internet of things in the field of agricultural production is still arelatively new subject for our country. The greenhouses were built in village many yearsago, they are managed and monitored manually. As an important project of increasingthe farmers’ income, greenhouses intensive management is necessary, and can save a lotof manpower, material resources and the cost of production. The research content of thisarticle is mainly about the Internet of things used in the facility agriculture greenhouses.Automation technology applied in agricultural production has made some progress inour country in recent years, the more mechanization planting and harvesting areincluded, but, for automated maintenance and management, we do so little. Somerelated research has been done in the automation technology applied in greenhouses,Including the collection of greenhouse environment parameters, thencollected data aretransformed to the PC for monitoring, The more work is the monitoring of temperatureand humidity, but it is also at the experimental stage, and has not still been widespreadpopularized. The research contents of this paper are based on the actual project as thebackground, and its aims is to get more extensive application.The main content of this paper is to apply the internet of things for greenhousesenvironment monitoring system, design the overall architecture of the system, thissystem is mainly composed of data acquisition terminal and server. We design theterminal model, the data acquisition part mainly includes the temperature, humidity, illumination and carbon dioxide concentration. We choose acquisition chip, design themeasurement circuit, the data is acquired by wireless sensors network, here we relatethe network forming process, we use the S3c2410based on arm core board as theconvergence node in the wireless sensor network, S3c2410has strong data processingability. The system kernerl can be compiled according to the needs, and burned into theborad. S3c2410uses the power supply. The data collected are transformed to the serverfor storage and processing, this paper design the display terminal for real-time dataacquisition and management, gives the prompt warning information for exceptionemergence. As a part of the server work, the Field Support includes two aspects:Domain Knowledge Base and the Prediction Model. With the help of experts, thedomain knowledge base is constructed. The Domain Knowledge Base is made up oftwo parts: words and reasoning, which records the growth characteristics of some cropsdetaily, and can do a state reasoning about the present characteristics of the crops. Thispaper use data from the server as the main sample data, and applys the least-squaremethod from engineering mathematics to achieve the acquisition parameters predictionfitting curve, this is also an innovative point in this paper, it is more advantageous to theinstruction of greenhouse planting technology. This system will link to the coolingsystem, adding and subtracting humidity system, adjusting the lighting system andadjusting the co2concentration system effectively in the future, it will realize the finalautomation management for greenhouses environment.
