Design And Research Of Intelligent Farm Monitoring System Based On ZigBee

As we all know,China has been a large agricultural country since ancient times,whose peasant population accounts for 56%of the total,so the traditional agricultural model has been unable to meet the demands of today's development.With the rise of wireless technology and the popularity of intelligent farms,wireless technology has been well used in intelligent farms.The system uses the ZigBee module to monitor the environmental changes and parameter information in the farm including tests of temperature and humidity,soil moisture and light intensity by combining the ZigBee network with the farm,and then transmits the detected informiation data to the PC through the RS232 serial port and the detected data information is displayed through the upper computer software,so that managers can remotely view and monitor the farm environment parameters,and adjust the environmental parameters of the farm through the remote control equipment.At the same time,the system can also adopt self-adjustment.When the detected environmental information is higher than a certain threshold,the control equipment automatically works;instead,it stops working.This thesis first describes the relevant theory of ZigBee network technology.According to the functional requirements of the system,it is divided into two parts:slave computer and host computer.The lower computer sets the ZigBee module in different areas of the farm,and the ZigBee module realizes the connection between ZigBee modules by Ad-Hoc Network,further realizing the data detection and transmission.Then,the ZigBee module sends the data detected by the ZigBee network to the PC through the RS232 serial port.The upper computer is to process and display the collected data,so that managers can clearly understand the changes in environmental parameters within the farm,and adjust or self-adjust the environment parameters of the farm through the remote control.The design tasks completed in this thesis are as follows:1.ZigBee module layout.The network connection between ZigBee modules uses mesh topology,and coordinator node realizing network creation and maintenance,router implementing forwarding and network development,the terminal nodeachieving information detection capabilities.The thesis also contains sensors Node selection and software design.2.Based on the ZigBee network in this thesis,a dynamic multiple cluster-head clustering algorithm based on energy balance is proposed,which can effectively reduce the energy consumption of the ZigBee module and make the ZigBee network longer.3.This thesis also realizes the upper computer software,well storing and displaying the data transmitted by the ZigBee module.Users can use the software for real-time monitoring and remote adjustmenton the farm environment,but also to realize automatic control of the intelligent farm.By setting the threshold to control the opening or closing of the adjustment equipment,intelligent farms unattended will be realized.
