Virtual transducers in service-oriented smart transducers network

Implementation of the Service Oriented Architecture (SOA) in the IEEE 1451 smart transducers network enables efficient data exchange and simple integration of new devices. The existing IEEE 1451 Web service implementation prototypes are normally developed using a general purpose platform. This paper presents a model of service-oriented network relying on the embedded smart transducers with integrated IEEE 1451 Web services. New entities such as algorithms and data displays are integrated in the network in a form of virtual transducers, and they also act as service providers. Network configuration and data exchange are controlled by the central server, while support for the configuration of individual devices is provided by the service-oriented content modification of Transducer Electronic Data Sheets (TEDS). A configuration example is demonstrated in a form of the service-oriented display presenting the same set of measured data using three different instances of the format-customized presentation TEDS.
