The Study on Remote Virtual Measurement Technology Based on Wireless Sensor Networks

In modern measurement technology, wireless sensor network has been widely used in the industrial and other fields. Threrinto,remote virtual measurement technoligy which use wireless network technology to obtain remote measuring data is a hot topics.In this paper,we ues wireless sensor networks to achieve remote measuring data,its emphases is the remote data transfer after measurement ,storing and using virtual instrument to data processing and analysing.we first give the typical structure of wireless sensor netwok measurement system,which includes four layers:node layer,network layer,communication layer and data layer. Thereinto,we use data fusion technology to achieve data compressing.Second,we analyse the basic principles of remote virtual measurement and give the P2P network communication flow based on DataSocket.Last,we give the double layer network measurement model based on P2P and the simulation structure. This proposed technique is well suited for various applications in remote data measurement and has good prospects.
