Design Of Greenhouse Microclimate Environmental Management App Based On Android Platform

This topic is part of new type agricultural machinery and equipment development project.The main purpose of the research is to apply the greenhouse environmental management system to the smart phone App,which facilitates the user's real-time monitoring and management of the greenhouse's internal environment.This will not only improve farmers'efficiency in agricultural production,but also promote to reduce the waste of manpower,financial and natural resources.Which popularizes the smart mobile devices in the greenhouse environment management technology.This paper designs the greenhouse microclimate management App based on the Android platform.Through analysis of the functional requirements and architecture of the system,the feasibility scheme of the App is determined,and the functional modulea and database system of the mobile App is designed.The functional modules include data monitoring module,irrigation management module and planting environment management module.Through the greenhouse environment management App,users can check the changes of environmental factors in any time period in the greenhouse,obtaining the data of environmental factors,such as:CO₂ concentration,light intensity,soil temperature and humidity,temperature and humidity in the air.The users can water and fertilize the plants of greenhouse by selecting different irrigation routes.In which the pH value of the soil in the greenhouse,the EC value of water and fertilizer,the proportion of fertilizer absorption and the time of water and fertilizer irrigation can be set.The irrigation strategies are selected according to the soil types and needs of crops in the greenhouse.In this paper,the edge folding algorithm is used to simplify the carbon dioxide control model based on the light and temperature coupling of the greenhouse.When the monitoring system breakdown,the parameters of environmental factor in the greenhouse can be obtained by the simplified algorithm,which can reduce the bad effect of that.The design of the greenhouse microclimate management software based on the Android platform enables the user to obtain the data of various environmental factors of the greenhouse in a period of time provided by the background server through the App application software at any time and anywhere.According to the obtained Data,the system regulates the internal environment of the greenhouse including the water and fertilizer regulation process.Which solve the problem of non-real time regulation of the internal environment of the greenhouse when manually managed,so that the crops of the greenhouse are in a good growing environment.
