标准范围

需要识别读取器在自动识别环境中检测到的数据载体。符号系统标识符概念为从读取器接收数据的设备提供了区分数据载体的标准化方式。ISO/IEC 15424:2008主要涉及条形码符号；因此，术语符号系统标识符、符号系统和条形码在整个ISO/IEC 15424:2008中被使用，尽管它们也旨在应用于其他数据载体。这种识别是通过向阅读器添加一个可选特征来实现的，该特征使阅读器能够在数据消息前加上一个标准字符串。该前导码包含关于解码符号(或其它数据载体)和读取器已经完成的任何处理的信息。除了一些可选特征的存在可以由读取设备检测到，而其他特征需要读取器来表达之外，信息没有被编码或以其他方式显式或隐式地表示在符号中ISO/IEC 15424:2008应结合相关符号规范阅读。ISO/IEC 15424:2008适用于自动识别设备通信约定，并标准化了来自条形码阅读器和其他自动识别设备的数据载体的报告。它指定由读取器生成并可由接收系统解释的前导码消息，该前导码消息指示条形码符号系统或发送数据的其他来源，以及与数据消息相关联的某些指定的可选处理特征的细节。

The need exists to identify the data carrier a reader detects in autodiscrimination environments. The Symbology Identifier concept provides a standardized way for a device receiving data from a reader to differentiate between the data carriers. ISO/IEC 15424:2008 deals mostly with bar code symbologies; the terms Symbology Identifier, symbology, and bar code are therefore used throughout ISO/IEC 15424:2008 although they are intended to apply to other data carriers as well.

This identification is achieved by the addition of an optional feature to readers enabling the reader to prefix a standard string of characters to data messages. This preamble contains information about the decoded symbol (or other data carrier) and any processing the reader has done. The information is not encoded or otherwise explicitly or implicitly represented in the symbol, except that the presence of some optional features may be detected by the reading equipment, whereas others require the reader to be expressly configured to implement them.

ISO/IEC 15424:2008 should be read in conjunction with the relevant symbology specifications.

ISO/IEC 15424:2008 applies to automatic identification device communication conventions and standardizes the reporting of data carriers from bar code readers and other automatic identification equipment. It specifies a preamble message generated by the reader and interpretable by the receiving system, which indicates the bar code symbology or other origin of transmitted data, together with details of certain specified optional processing features associated with the data message.
