Abstract


Wireless sensor network technology integrated sensor , embedded computing , of modern network as well as wireless communications and distributed information processing technology is on the forefront in the current international hot research field . Wireless sensor network applications to greenhouse environmental monitoring systems , self-organizing network , wireless data transmission and intelligent control , can effectively solve the difficult wiring of traditional greenhouse complex networking and difficult to maintain shortcomings . At the same time , the introduction of wireless sensor network technology to agricultural production , and also has great significance for achieving the modernization of agriculture . This selection of greenhouse environment monitoring system is very high requirements for power consumption , cost and stability with a low-power , low-cost , high- stability characteristics of ZigBee wireless sensor network technology, building set for monitoring temperature and humidity greenhouse wireless sensor network model . The paper first describes the architecture of the ZigBee protocol and ZigBee networks , made ??an in-depth study and TI's Z-Stack protocol stack and workflow . The papers around three main aspects : the overall design of the system , the node hardware design node software design . (1 ) In accordance with the actual requirements of the greenhouse environment monitoring , the paper proposes a new greenhouse environment monitoring system based on ZigBee technology solutions , and the overall structure of the system is given . ( 2 ) wireless sensor network node hardware design . From the cost, power consumption , and many other considerations , we designed a CC2430 chip as the core structure of the node , and each hardware component of the component selection and related peripheral circuit design . ( 3 ) based on the Z-Stack protocol stack of wireless sensor network node software design , including the design of network programming, data transceiver programming as well as temperature and humidity acquisition program . The last to carry out experimental tests of greenhouse wireless sensor networks , including: wireless communications and networking test , temperature and humidity acquisition testing , testing , and power consumption of packet loss rate calculation . The experimental results show that the design of ZigBee in this article greenhouse environment monitoring system solution is entirely feasible .
