Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with specific examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] 1. Data table construction method based on automatic identification identifier

[0021] (1) Sequential storage structure based on automatic identification identifier

[0022] The sequential storage structure is the basis of the data table storage structure. The following uses the identifiers in GB / T 16986-2009 "Commodity Barcode Application Identifiers" to construct an example of the sequential storage structure (using data identifiers is also similar).

[0023] 1. Format and Application Identifier Standards

[0024] According to the ISO / IEC 15434 standard "Information Technology Large-capacity Automatic Data Collection Media Syntax", the data format in the label is a double-layer encapsulation structure, th...

Abstract

The invention discloses a data table storage method based on an automatic identification identifier. A data table based on an automatic identification identifier comprises data table header construction and data table recording construction; during the data table header construction, a data table header defines a data table identifier field at a starting line, and the data table identifier field meets the requirement of the automatic identification identifier on constructing data format; during the data table recording construction, for a plurality of data records of a storage data table after the data table head, the data records are stored by adopting a variable-length identifier field data table or a fixed-length identifier field data table. Compared with the identifier sequential storage structure, the variable-length identifier field data table or fixed-length identifier field data table storage scheme has the advantages that the storage space is saved, and great significance is realized on the automatic identification identifier with the limited storage space.

Description

technical field [0001] The invention relates to the technical field of barcode and radio frequency identification, and more specifically relates to a data table storage method in an automatic identification label based on identifier technology. Background technique [0002] Automatic identification labels based on various barcodes and radio frequency identification technologies are generally pasted / installed on items and flow in various links of logistics, from the initial item sender writing relevant data information into the label, to the subsequent receiver To read the data information in the label, it is necessary for multiple parties to agree on an understandable way to construct the data format in the label so that it can be read and analyzed by multiple parties to obtain correct information. Initially, people directly write a variety of information based on the ASCI I character code to form a string of characters and write it directly into the label, and the reader ca...
