Wireless Indoor Environment Monitored Control System Based On ZigBee Technology

Agricultural environment sensor serves as one of the main techniques in the modernagricultural development. With the rapid development of technology, the method ofgreen-house environment monitored control system had been changed a lot. Many reasons,like the cable corruption and complicated arrangement of wire, make the traditional wiredcontrol system not use in the future. But the wireless sensor networks technology can avoidthose problems. Wireless sensor networks green-house environment monitored control systemadopts the modern communication technology to the control system. It can avoid thelimitations of the wire arrangement in the presence and make the process convenient,real-time and low-cost. This technology has well adaptability and development potential.We made environment control system as research object, developed programs accordingto the feature green-house, and designed the green-house environment monitored controlsystem of wireless sensor networks technology based on Zigbee. This system achieved thecommunication among the sensor nods, gathering nodes and executive nodes. Among them,the sensor nodes are using to collect information, gathering nodes are using to summarizethem, and the executive nodes are using to execute simple control instructions. The coredevice of the nodes which we used in this paper is the Chip CC2430produce by TexasInstruments (TI), study the Z-Stack protocol and fulfill the application program withIARworkbench. We apply Visual Studio2005to programme the software which makes peopleacquire the information of the green-house easily. This software has a visualized interface,and the data from which makes a scientific proof to the green-house environment regulation.In the future, the green-house environment monitored control system of wireless sensornetworks technology based on Zigbee will apply to the agriculture more and more. With theimprovement of its function, this technology will provide scientific basis in the developmentof modern precision agriculture.
