Greenhouse Monitoring System Based On Embedded

As the indispensable composition in facility agriculture,greenhouse has become the main force of agricultural counter-season production.Because the growing status of greenhouse crops is greatly influenced by indoor environment factors,so the topic that how to use modern science and technology to real-time,networked and intelligent monitor greenhouse becomes more and more important.Based on the practical need of greenhouse monitoring,this study utilizes embedded technology,computer control technology,wireless communication technology and transducer technology to design the greenhouse monitoring system based on embedded.The system hardware is made up of acquisition control terminal and embedded controller.The system monitoring software is designed by Qt Creator.The system has the advantage of flexible wiring,simple operation,strong adaptability,etc.The acquisition control terminal mainly realizes the work of data collection and equipment control.Modular design the terminal and detail the hardware and circuit.The terminal runs Z-Stack to form a Zigbee wireless communication network and realize established function.Introduce the specific communication protocol.Build the Linux development environment for the embedded controller.The controller completes the transplantation of Linux operating system,cross-chip driver and Qt.Writing a program to realize serial port communication,equipment control,data display and video capture and other functions to real-time monitor the greenhouse.The controller uses TCP / IP protocol to communicate with PC to transmit the data information.The system monitoring software runs remotely through the TCP/IP protocol to receive the data transported from the embedded controller according to the user command.The system monitoring software mainly realizes real-time monitoring,video monitoring,data storage and other functions.
