Agricutural Greenhouse Monitoring System Based On Embedded

China is a traditional agricultural country,but at present most of the agricultural management has to rely on manual completion,which is not only time-consuming and laborious,but also inefficient.The monitoring system of agricultural greenhouse based on embedded technology makes use of the most advanced embedded technology and Internet technology to achieve the acquisition of field environmental information and timely feedback to farmers.At the same time,farmers can remotely control the hardware equipment in greenhouse at any time and anywhere,which not only improves the efficiency of agricultural management,but also greatly saves the cost of agricultural production.Firstly,the research background and development trend of embedded intelligent agricultural system are consulted.On this basis,a monitoring system for agricultural greenhouse based on embedded technology is designed,which combines the computer skills acquired during the postgraduate period.The application of sensor technology,Zigbee technology,embedded technology,combined with Qt to realize remote network monitoring of client.This design has four modules:client,embedded network server,data acquisition terminal,client program and interface design are implemented in Qt Creator development tool.TCP/IP connection is established with embedded network server,which mainly provides login and annotation.Books,forgetting passwords,modifying passwords and other functions.Embedded network server takes Exynos 4412 as its core processor and Linux as its operating system.Its main function is to process the registration,login,request and control commands of multiple clients.Zigbee wireless transmission module adopts enhanced 8051 CPU to realize wireless transmission of embedded network server and data acquisition terminal.The data acquisition terminal module adopts LPC11C14 chip,which mainly realizes the acquisition of temperature and humidity information,illumination information and equipment control request through Zigbee wireless transmission module,and completes the control of related hardware.After testing,the system can run steadily,the data can be displayed accurately in the client interface,and the network transmission rate is stable.Users monitor the field environment at any time,and control the hardware of the planting site.
