Research Of Greenhouse Intelligent Control Based On The LabVIEW And ZigBee

Intelligent monitoring becomes one of the important research hot spots with the rapid development of facility agriculture. The large area is the main characteristic of the monitoring field, so in order to get more precise environment parameters in the greenhouse of each region, It needs to deploy a large number of sensor nodes in the greenhouse to constitute a large detection network, then we can detect the air temperature and humidity, soil temperature and humidity, concentration of CO2, light intensity and soil environment PH value and so on through all kinds of sensors in the green house, and then adjust these parameters to make them suitable for the growth of the crops by all kinds of execution unit, and then realize the greenhouse intelligent monitoring.Traditional detection method is to use the instruments of greenhouse,and then to adjust and improve the environment by the execution of corresponding equipment. And the cable connection is always the method of detection and control system,It is more complicated to wiring and easier to cause cables crisscross, and even always with difficult issues such as installation and maintenance in the greenhouse.If we use wireless sensor network instead of wired network, It not only avoids the complexity and difficulty in traditional cable transmission of wiring and the malfunction inspection, and also can reduce the cost.Wireless sensor network is an important technology to meet the needs of greenhouse application and can replace the traditional way of greenhouse facilities cable connection.It goes to be the important development direction in the future to use the greenhouse intelligent control technology and the wireless sensor network technology to deploy greenhouse cluster wireless network system and realize the optimization control of greenhouse environment parameters and the wireless、networking and intelligent in the whole process of crop growth.This paper references the domestic and foreign research situation about the greenhouse intelligent control and test system application, and designs a kind of greenhouse intelligent control system based on Lab VIEW and Zig Bee by the integrated use of sensorsmonitor technology. By sensors of Zig Bee sensor nodes we can acquire the greenhouse environment parameters and transfer them to Zig Bee coordinator through the Zig Bee wireless network,and then Zig Bee coordinator communicates with PC by RS232 serial port,then the PC software can real-time dynamically display thegreenhouse environment parameters, then wecan make an intelligent control to the execute device of greenhouse.It provides the technical support for timely grasp of the crop growth environment to realize the information early warning and decision-making and management.
