Description / Abstract:
This part of ISO/IEC/IEEE 21451 defines communication methods
and data formats for transducers (sensors and actuators)
communicating with RFID tags. This part of ISO/IEC/IEEE 21451 also
defines Transducer Electronic Data Sheet (TEDS) formats based on
the ISO/IEC/IEEE 21451 series of standards and protocols for
accessing TEDS and transducer data. It adopts necessary interfaces
and protocols to facilitate the use of technically differentiated,
existing technology solutions. It does not specify transducer
design or signal conditioning.
There is currently no openly defined independent interface
standard between transducers and RFID tags. Each vendor builds its
own interface. Without such a standard, transducer interfacing and
integration to RFID tags and systems are time-consuming and all
vendors' duplicated efforts are economically unproductive. The
purpose of this part of ISO/IEC/IEEE 21451 is to provide interfaces
and methods for interfacing transducers to RFID tags and reporting
transducer data within the RFID infrastructure. It also provides
the means for device and equipment interoperability.
