Design And Application Of Environmental Intelligent Monitoring System For Greenhouse

Greenhouse technology widely used in agriculture has become an important part of efficient agriculture.In this paper,for the current situation of large vegetable growing plants,is aimed to monitor growth environment of crops in greenhouse,especially the temperature,humidity and light conditions of crop growth,according to the actual needs of the situation and the existing technology,the greenhouse intelligent monitoring system design projects was suggested.This paper designs and analyzes a comprehensive embedded system to realize the collection and display of various environmental data(including temperature,humidity and light intensity)in the greenhouse.The main function of the system is to automatically collect the dynamic indicators(temperature,humidity and light intensity)of the commonly used plants in the greenhouse,and to show the convenience of the growers to control the growth environment of the vegetables in real time.The greenhouse data collection terminal mainly implements the data collection,data display and data transmission of the greenhouse environment.First use different sensors,the temperature in the shed,humidity and light intensity of these analog conversion can be processed by the microcontroller digital,and the various data displayed on the digital tube to facilitate the user real time query,and for the remote transmission of data.The temperature display environment receives the data from the data acquisition terminal,then processes the data accordingly,and finally displays the data in the form of characters and curves on the LCD screen.System also has the human-computer interaction capability,and the relevant parameters setting.Embedded WEB server receives the data from data acquisition terminal;the server can be accessed from the computer at any time on the site to observe the greenhouse environment.At the end of this paper,through the overall system debugging,the system is stable,complete the expected function,and can show the experimental results.
