标准摘要
[中文适用范围]: 本国际标准和 ISO/IEC 15962 中规定了用于在 RFID 系统中交换信息以进行物品管理的数据协议。 要完全理解整个数据协议,需要这两个国际标准;但每个标准都侧重于一个特定的接口: •本国际标准涉及与应用系统的信息接口。 • ISO/IEC 15962 涉及数据处理及其向RF 标签的呈现,以及从RF 标签捕获的数据的初始处理。 该国际标准重点关注应用程序和数据协议处理器之间的接口,包括传输语法的规范以及应用程序命令和响应的定义。 它允许以标准化方式指定数据和命令,而与 ISO/IEC 18000 的特定空中接口无关。 该国际标准 • 提供了有关如何将数据呈现为对象的指南; •根据ISO/IEC 9834-1 定义对象标识符的结构; •指定支持在应用程序和RF 标签之间传输数据的命令; •指定支持在RF 标签和应用程序之间传输数据的响应; •按照 ISO/IEC 8824-1 的规定,使用 ASN.1 提供所有流程的正式描述; •根据ISO/IEC 8825-1 的基本编码规则,指定从应用程序传输数据和向应用程序传输数据的传输语法。 预计本国际标准将用作开发适合特定应用或特定射频设备的软件的参考。 注: 按照惯例,在国际标准中,长数字由空格字符分隔,作为“千位分隔符”。 本国际标准未遵循此约定,因为对象标识符的弧是由空格分隔符定义的(根据 ISO/IEC 8824 和 ISO/IEC 8825)。 由于这些弧的正确表示对于本国际标准至关重要,因此除了表示对象标识符的两个弧之间的节点之外,所有数值都没有空格分隔符。 [外文原描述]: The data protocol used to exchange information in a radio-frequency identification (RFID) system for item management is specified in ISO/IEC 15961:2004 and in ISO/IEC 15962:2004. Both are required for a complete understanding of the data protocol in its entirety; but each focuses on one particular interface: ISO/IEC 15961:2004 addresses the information interface with the application system.ISO/IEC 15962:2004 deals with the processing of data and its presentation to the RF tag, and the initial processing of data captured from the RF tag. ISO/IEC 15961:2004 focuses on the interface between the application and the data protocol processor, and includes the specification of the transfer syntax and definition of application commands and responses. It allows data and commands to be specified in a standardized way, independent of the particular air interface of ISO/IEC 18000. ISO/IEC 15961:2004 provides guidelines on how data shall be presented as objects;defines the structure of object identifiers, based on ISO/IEC 9834-1;specifies the commands that are supported for transferring data between the application and the RF tag;specifies the responses that are supported for transferring data between the RF tag and the application;provides a formal description of all the processes using ASN.1, as specified in ISO/IEC 8824-1;specifies the transfer syntax, based on the Basic Encoding Rules of ISO/IEC 8825-1, for data to be transferred from and to the application. It is expected that ISO/IEC 15961:2004 will be used as a reference to develop software appropriate for particular applications, or for particular RF equipment.
