Research And Application Of Active Service Technology Based On ZigBee

With the development of wireless sensor network and data processing technology in big data,active service technology has been paid more and more attention.Different applications of active service technology have been proposed.Applications of active service technology can provide various types of active services without any artificial operations.The optimization of active service technology and active service application architecture is helpful to improve the quality of service.Therefore,the research of active service technology and its application has practical value.To solve problems of the architecture of active service applications such as waste of the capability of gateway and inflexible service,this paper presents an architecture based on ZigBee sensor network and an intelligent gateway,which providing local and remote active service.Also,an outlier detection algorithm of temperature and humidity based on clustering of difference is proposed,which can adapt to the application of low performance nodes.This paper designs and implements an active service prototype system based on ZigBee network.In the system proposed,the problem of data caching in sensor network is solved and a solution of data communication in active service applications is proposed.The test result of the prototype system show that the outlier detection algorithm of temperature and humidity based on clustering of difference proposed work well with less physical resources,which meet the performance requirements of nodes with low computing capacities.The proposed active service prototype system based on ZigBee network can work active and provide service such as abnormal event records,environmental monitoring and other related services.
