标准摘要
[中文适用范围]: ISO/IEC 15961 和本国际标准中规定了用于在 RFID 系统中交换信息以进行物品管理的数据协议。 为了全面理解数据协议,需要这两个国际标准;但每个都专注于一个特定的界面: ISO/IEC 15961 解决了与应用系统的接口问题。 ?该国际标准涉及数据处理及其向射频标签的呈现,以及从射频标签捕获的数据的初始处理。 本国际标准重点关注根据 ISO/IEC 15961 中定义的应用命令对传输语法进行编码。 编码位于逻辑存储器中,作为由询问器寻址的 RF 标签的物理存储器的软件模拟。 这个国际标准?定义对象标识符的编码结构; ?指定适用于编码数据的数据压缩规则; ?指定用于高效编码语法特征的前体; ?指定数据的格式化规则,例如取决于是否使用目录; ?定义应用程序命令(例如锁定数据)如何传输到标签驱动程序; ?定义与应用程序的其他通信。 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 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 15962:2004 focuses on encoding the transfer syntax, as defined in ISO/IEC 15961:2004 according to the application commands defined in that International Standard. The encodation is in a Logical Memory as a software analogue of the physical memory of the RF tag being addressed by the interrogator. ISO/IEC 15962:2004 defines the encoded structure of object identifiers;specifies the data compaction rules that apply to the encoded data;specifies a Precursor for encoding syntax features efficiently;specifies formatting rules for the data, e.g. depending on whether a directory is used or not;defines how application commands, e.g. to lock data, are transferred to the Tag Driver;defines other communication to the application.
