GS1标准条形码和通用条形码符号之间有什么关系? [英] What is the relationship between GS1 standard barcodes and generic barcode symbols?

问题描述

我们正在我们的应用程序中实现GS1线性条形码(代码128，代码39)和GS1 2D条形码(数据矩阵，PDF41 [sic])，以及GS1 DataBar条形码.由于我是新手，所以我对GS1型条形码几乎没有疑问.

1. GS1标准条形码和通用条形码符号之间有什么关系?
2. 可以将任何文本制成GS1型条形码(例如GS1 DataMatrix)还是必须遵循某种强制性格式?

谢谢.

解决方案

快速了解:没有GS1代码39或"PDF41"(I 假定您的意思是PDF417，但与Code 39一样，这不是 GS1采用的载波符号.)

除专门设计的GS1 DataBar条形码系列外，其余GS1条形码符号是各种通用ISO/IEC条形码标准的应用标准"，适用于供应链行业，并由 GS1通用规范.每种格式的创建都是针对某些预先存在的运营商符号体系(代码128，数据矩阵，QR代码)的专业化，这意味着它们可以在现有规范的范围内工作，以产生更为严格的特殊用途变体，并对其进行优化在特定应用中使用-例如，通过减少可用符号大小的范围，对数据容量施加限制并为封装的数据指定特定的结构.

关于具有强制性的数据结构，在运营商符号体系中可用的GS1专业化要求使用"FNC1处于第一位置"机制来指示是否存在符合以下要求的GS1应用程序标识符标准格式的数据: GS1规格.因此，产品数据使用这种标准格式表示，并使用与GS1符号体系大致相似的方案在载波符号内进行编码.

此答案的提取"部分提供了根据GS1 AI标准格式结构格式化数据的详细信息./p>

We are implementing GS1 linear barcodes (Code 128, Code 39) and GS1 2D barcodes (Data Matrix, PDF41 [sic]) and also GS1 DataBar barcodes in our application. Since I am new to this, I have few questions regarding GS1-type barcodes.

1. What is the relation between GS1 standard barcodes and generic barcode symbols?
2. Can any text be made into GS1-type barcode (e.g. GS1 DataMatrix) or does the text have to follow a certain mandatory format?

Thanks in advance.

解决方案

A quick nit: There is no such format as a GS1 Code 39 nor "PDF41" (I presume that you meant PDF417 but as with Code 39 this is not a GS1-adopted carrier symbol.)

With the exception of the purpose-designed GS1 DataBar family of barcodes the remaining GS1 barcode symbologies are "application standards" of various general-purpose ISO/IEC barcode standards adapted for dedicated use within the supply chain industry and are specified by the GS1 General Specifications. Each format was created as a specialisation of some pre-existing carrier symbology (Code 128, Data Matrix, QR Code), meaning that they work within the limits of the existing specification to produce a more-restricted, special-purpose variant that is optimised for use in their particular application – for example by reducing the range of available symbol sizes, applying constraints on the data capacity and specifying a particular structure for the encapsulated data.

With regard to having a mandatory data structure, where available in the carrier symbology the GS1 specialisations mandate the use the "FNC1 in first position" mechanism to indicate the presence of data that conforms to the GS1 Application Identifier standard format described by the GS1 specifications. The product data is thus represented within this standard format and encoded within the carrier symbol using a scheme that is broadly similar across the GS1 symbologies.

The "extraction" part of this answer gives details of formatting data according to the GS1 AI standard format structure.
