Intelligent Agriculture Greenhouse Management System Based On Wireless Sensor Network

The development of internet of things provides a powerful technological support for the intelligent agriculture.In the intelligent agriculture,it is a crucial measures for the development of agricultural by applying various sensors to monitor and control the environment of greenhouse for building the best growth environment of crop growth.The progressiveness and advantages of the intelligent agriculture is embodied in the combination of the technology of various sensor,automatic control,network with farm infrastructure.By applying the terminal to acquire the data of production,detect and predict the problem during the growth of crop timely.Finally we can manage the crop growth process,promote agricultural productive efficiency and make the operate of farm more efficient and easy.This design studies the collection and transmission of informations which are based on wireless sensor network and choose the Zig Bee technology as the underlying communication technology and develop the terminal control system in order to achieve intelligent management of agricultural process.The whole system consists of three layers,the bottom is information acquisition layer of wireless sensor network and it uses ZigBee technology to build a star data acquisition network,every ZigBee node connected to a number of sensors for real-time data collection.The main sensors include temperature and humidity sensors,light intensity sensors,soil moisture sensors,etc..The node is also connected to a variety of implementing agencies mainly including relays,pumps,fans stepper motors and so on.The middle layer is the communicational layer,which is composed of the server with Wi-Fi support.The intelligent management database is designed in the server to realise the corresponding data management process.The top layer is the application layer.The system adapts mobile terminal control and design a friendly interface which has rich functionality for the convenient.It can effectively achieve the underlying data and the underlying implementation of the control.The system has two advantages.First,it uses ZigBee multi-hop self-organizing capabilities to form an effective self-organizing network,so that the sensor can be setand changed flexible;second,using ZigBee protocol stack and the Internet to realize the seamless data transmission,in order to achieve the data collection,processing and transmission of the three major functions.This paper introduces the planning and structure design process of the whole monitoring system,and analyzes the design and development process of hardware,database,underlying ZigBee protocol stack,server program and client program.
