Research On Test System For Modern Greenhouse Environment Parameters Based On ZigBee Wireless Communication Technology

Agricultural environment sensor serve as one of the main techniques in the modern agricultural development . Adopt wireless sensor networks technology to monitor environment in the greenhouse , solving the problem of traditional trivial wiring , rearrange the seating in the greenhouse when the crop is change and other disadvantage factors , realized to automatic monitoring the environment parameter in the greenhouse based on wireless has wide application . The article based on typical greenhouse environment feature and long-range environmental monitoting control requirement , work out a system design scheme . Based on this scheme , The work including selection for sensor ; sensor acquisition node disign ; terminal collection node design ; and controller design of hardware and software .In this measurement and control system , a single greenhouse as a measurement control area for wireless sensor networks . It takes ZigBee production solutions CC2430 single-chip wireless node devices as a core hardware which is produced by TI(chipcon) recently .This networks adoptiong different sensor measure node and node which can sinmply executive control , that form the wireless sensor networks . sensor measure node is used to mesure the parameter of soil temperature , soil moisture , air temperature , air moisture and so on , as for to know the environmental state of greenhouse; gathering node is used to communication with end-upper computer .After introduced the wireless sensor networks and the node principle , take use of IAR workbench to programing the acquisition node and collection node . Take use of Visual C++ to realize the serial port software design , and compiled transmission and the receive procedure , as to achieve man-computer interaction , it provided scientific basis for proper control of greenhouse environment . And the experiments verified the design is feasible.At the end ,there is a summary of this paper and what things need to be done in the near future . The critical technique of the modern greenhouse including acquisition , transmission , procession and control in environment parameter , the modern greenhouse based on ZigBee wireless networks technology examination system provide a scientific basis for installation agricultural complex environment exactly regulate .
