Power management in service-oriented smart transducers network

IEEE 1451.0 standard defines common smart transducers characteristics and interfaces, as well as the electronic specification known as Transducer Electronics Data Sheet (TEDS). Introduction of Web services based on the IEEE 1451.0, further improves interoperability in smart transducers network. On the other side, energy consumption represents an important aspect in the transducer application and algorithm design, especially in the case of devices with battery power supply. In this paper, we propose a general TEDS format for low-power mode configuration, with independent activation/deactivation of device segments, and we describe how energy can be saved in the service-oriented smart transducers network. Test example is given in the form of service-oriented smart transducer with independent power control of temperature sensor channel.
