2.1.4 Study and establish a draft standard for related technologies of electronic labels for domestic trade containers

A new electronic label structure system suitable for containers in my country is proposed as a standard for automatic identification of port containers. The goal is to create a migration path between ports to help people transition from the existing containerless electronic labelling method to adopting the new electronic labelling method. The electronic label structure system adopts the basic structure of the Global Trade Number (GTIN).

In the design of electronic label system, advanced, mature and practical technology is adopted. The adopted hardware equipment and software system meet the requirements of standardization and openness, and have expansibility and flexibility. In addition to this standard, the design of the electronic label system should also comply with the relevant national and local design specifications and regulations. The protocols, buses, interfaces, etc. used in the electronic label equipment should adopt the corresponding industry standards and be in line with international standards.
