| In recent years,the development of Internet of Things has atrracted a more and more attention from many countries.As one of core technology of IoT,wireless sensor networks is becoming more and more important.The 6LoWPAN sensor network combine by IPv6 protocol and IEEE 802.15.4 standard,with low power consumtion,rich IP resourses and high stability,which leads the way of wireless network envolving and expands the scope of application of the Internet of thingsThe IoT system described in this paper can be applied to many environment,such as smart home,greenhouse,agricultural or industrial environment,providing data of humility,temperature and illumination.This paper starts with studying existing 6LoWPAN sensor network,including relative protocol,hardware and circuit,trying to reduce the comsumption of senser node.The integrated gate way is designed on open source development kit Beaglebone Black,which provide many ways for managing data from sensors by programming,such as Modbus and Web.The IoT system includes sensor network node design,integrated gateway design,server application and web server design based on Nodejs.At the end of this paper,the test of the comsumption of senser node,socket connetction,Modbus communication and performance of web server reaches the expectation and requirements. |
