Abstract:

In view of the feature of greenhouse environment, this paper proposed a greenhouse remote tele-monitoring system based on 3G wireless communications technology and VPN (Virtual Private Network) network technology. The system can establish a wireless virtual private network between greenhouse field devices and central server, realizing automatic collection of data, remote transmission, storage management, web publishing, analysis and achieving the remote auxiliary control of greenhouse equipment control at the same time. The results showed that: the system was designed reasonable, reliable and can meet data acquisition of a variety of environmental factors and multiple remote control of greenhouse accessories. View of the universal framework used in design techniques, the system extended to use to other agricultural areas, such as agricultural condition monitoring, meteorological disaster monitoring and early warning and so on, had huge application demand.
