National bodies that are members of ISO or

17、 IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, g

18、overnmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives

19、, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the nati

20、onal bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 24753 was prepared by Joint Technical Committee ISO/IEC J

21、TC 1, Information technology, Subcommittee SC 31, Automatic identification and data capture techniques. BS ISO/IEC 24753:2011 ISO/IEC 24753:2011(E) vi ISO/IEC 2011 All rights reservedIntroduction The technology of radio frequency identification (RFID) is based on non-contact electronic communication

22、 across an air interface. The structure of the bits stored in the memory of the RFID tag is invisible and accessible between the RFID tag and the interrogator only by the use of the appropriate air interface protocol, as specified in the corresponding part of ISO/IEC 18000. Since the initial publica

23、tion of ISO/IEC 18000, it has become possible to add sensors to the RFID tag using various physical methods, but always using the air interface protocol as a consistent means of communicating between the RFID tag and the interrogator. For sensor information, functional commands from the application

24、and responses from the interrogator are processed in a standard way. This allows equipment to be interoperable and, in the special case of the sensor attached to or integrated within an RFID tag, enables configuration parameters to be encoded in one systems implementation with the resultant sensory

25、information to be read at a later time in a completely different and unknown systems implementation. The data bits stored on each RFID tag and sensor must be formatted in such a way as to be reliably read at the point of use if the sensor is to fulfil its basic objective. The integrity of this is ac

26、hieved through the use of an application protocol, for example as supported by the functional commands specified in ISO/IEC 15961 and as specified in ISO/IEC 24791. Manufacturers of radio frequency identification equipment (interrogators, RFID tags, etc.), manufacturers of sensors, and users of RFID

27、 technology supporting sensors each require a publicly available application protocol. This International Standard specifies the sensor encoding and processing rules, which are independent of any of the air interface standards defined in the various parts of ISO/IEC 18000. As such, the sensor encodi

28、ng and processing rules are consistent components in the RFID system that can, independently, evolve to support additional air interface protocols and different types of sensors. This International Standard specifies the overall process and methodologies developed to format and process sensory infor

29、mation in a standardized manner and provide an interface with the appropriate air interface protocol. The transfer of sensory information and other related data to and from the application is supported by the use of the object identifiers standard, as defined in this International Standard. BS ISO/I

31、nimum application protocol to support sensors and the monitoring of batteries in conjunction with RFID tags utilizing the air interface as defined in the ISO/IEC 18000 series. This application protocol for sensors applies to RFID tags irrespective of their operating frequency. This application proto

32、col is agnostic to how the sensor(s) are connected to or integrated within the RFID tag; however, the communication between the interrogator and the sensor(s) is always through the RFID tag. This will allow the interrogator and application to understand a compliant sensors characteristics and proces

33、s its information without prior knowledge of that sensor. This will allow sensors to announce their sense activity and the units of measurement to the interrogator. This International Standard provides common encoding rules for identifying sensors, their functions, and their delivered measurements.

34、It also defines the process rules to support the following functions: selecting and de-selecting a particular sensory function when more than one is supported by the RFID tag; NOTE The measurement of time or battery life can be considered as separate sensory functions. setting sensor parameters both

35、 initially and ongoing; starting and stopping the monitoring function of a sensor; accessing sensor data; and carrying out basic processing of sensor data and interpreting this into a format that is meaningful for an application. 2 Normative references The following referenced documents are indispen
