The Research On Ganoderma Environmental Monitoring In Wireless Sensors Networks

Wireless sensor network ( Wireless Sensor Network, WSN) is a kind of newly arisen network technique, It has a certain function of information transport network which is made by several and dozens or even hundreds of sensors nodes by wireless communications technology . With the development of wireless communications technology, wireless sensor network has been able to realize to provide users with real-time information service. People can collect and monitor the information of temperature and humidity, light intensity and carbon dioxide levels in the monitoring environment by wireless sensor network technology Wireless sensors network is widely used in the army, agriculture, industry and medical care. This text mainly studies a kind of wireless sensors network system that used for monitoring Ganoderma cultivation environment.Firstly, this article introduces the study of background and meaning of wireless sensor network, the application of advantages of wireless network sensor in Ganoderma environmental monitoring and home and abroad to study the status quo. Secondly, in analyzing the characteristics and demanding foundation of the monitor system, according to the system actual target and principle, the research designed a kind of wireless sensors network that used for monitoring Ganoderma cultivation environment, it mainly studies the system structure of that system. This article introduced detailed the designs of network nodes processors, wireless communication modules and the sensor module, and proposed design solution of the use of Atmegal28 processor modules of ATMEL company and CC1000 communication modules of Chipcon company integration in the same piece of chip design. Thirdly, it mainly introduces the dynamic wireless network formation protocol and network topology, mainly introduced IEEE802. 15.4 and ZigBee protocol, and the research system uses the cluster of trees topology structure and static methods and with certainty the area of the working methods. Fourthly, adopt the TinyOS operate system establishment system platform to carry on a data to deliver a test to the node chip and process simulation in topology structure of system. The results indicate that the system have great value in use in real-time data collection of Ganoderma cultivation environmental monitoring. Finally, on the work carried out summary is at the next step forward looking.
