标准摘要
[中文适用范围]： 本国际标准适用于自动识别设备通信公约，规范了条码阅读器和其他自动识别设备的数据载体报告。 它规定了由阅读器生成并可由接收系统解释的前导码消息，该消息指示条码符号或以太坊传输数据的来源，以及与数据消息相关的某些指定的可选处理特征的细节。 [外文原描述]： 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.
