Design And Development Of Agricultural Greenhouse Intelligent Control System

Agricultural greenhouse is of great significance for our country's agricultural production,it not only can improve the income of farmers,can also satisfy the anti-season cultivation of crops and south north,summer winter wheat,let the consumer was able to safety in all the year round to eat fruit and vegetables,so agricultural greenhouse is an indispensable part in the facility agriculture.However,most of them are traditional agricultural greenhouses at the present stage,which are characterized by relatively low construction cost and can meet the basic conditions such as crop off-season growth.With the development of Internet of things technology and the proposal of agriculture 4.0,it is necessary to design and build agricultural greenhouses with intelligent control functions.Intelligent agricultural greenhouse not only needs advanced intelligent control system,but also needs a variety of sensor systems.Sensor system can be implemented on agricultural greenhouse air temperature and humidity,soil temperature and humidity,light intensity affect plant growth environment of key parameters,such as monitoring,at the same time through the DL-LN33 wireless networks to control panel,control panel sends commands to the control system,a control system to control,irrigation,ventilation,heating,etc.At the same time,users can observe the environment inside the agricultural greenhouse through the client in real time and manually intervene the control system.This paper is based on the rapid development of agricultural information,using mature sensor technology and ARM development board,through the analysis of plant growth environment,combined with the Internet of things to achieve the monitoring and control of the environment of agricultural greenhouse.The design is based on agriculture greenhouse intelligent control as the goal,by designing a sensor can monitor environment factor in greenhouse control system provide the environment parameter,ARM control surface parameters is analyzed and complete display,upload client,send commands to control system,control system receives instructions to finish the work,achieve can realize the intelligent management of agricultural greenhouse,also can realize visualization of agricultural greenhouse.Relative to the control system design of the existing agricultural greenhouse,compared to not only integrated intelligent monitoring of the greenhouse environment factor,can also according to the detected data are analyzed and intelligent control,through the sensor and the wireless network,make the management of agricultural greenhouse and production to be more precise,reduce the waste of resources and human resources,so in the future of agriculture greenhouse has a good prospect in development and advantage.
