A New Distributed Measurement Architecture for Applications of Networked Smart Sensors

A new distributed measurement architecture specially designed for applications of networked smart sensors over Internet is presented in this paper. The architecture covers three key areas for developing high-level distributed measurement applications, including: standardized transducer interfacing, open network communications and implementation of Internet access. With a reference to IEEE 1451, a networked sensor prototype has been developed to serve as the lowest level of the proposed architecture. Experiment results of a demonstration project have proved that the architecture can facilitate interfacing smart sensors with various field buses and enable Internet access of networked sensors. The original Website of this demonstration project is offline now, but a video of the demonstration project can be downloaded from http://robotsensor.3322.org/websensor/
