《GB/T 38662-2020物联网标识体系 Ecode标识应用指南》由TC287（全国物品编码标准化技术委员会）归口，主管部门为国家标准化管理委员会。
Introduction
Analysis of the core content of the standard
| Technical elements | Traditional identification system | Ecode identification system |
|---|---|---|
| Coding capacity | Limited | Theoretically unlimited expansion |
| Carrier compatibility | Single carrier | Support one-dimensional barcode, two-dimensional code, RFID, etc. |
| Management architecture | Centralized | Distributed registration analysis |
Technical Specifications of Coding Structure
Ecode adopts a three-section structure of V+NSI+MD:
- Version number (V): Identifies the version of the coding rules
- Coding system identifier (NSI): 4 digits identifying different industry systems
- Master code (MD): Variable length entity code
Key points for the implementation of data carriers
One-dimensional barcode storage case
Barcode of a salt product class=instrument>6901234567892 is converted to Ecode: 100036901234567892, and its symbol structure strictly follows:
- Left blank area (≥10 modules)
- Start character (11 modules)
- Ecode start character
- Encoding content area
- Check character
Industry application implementation suggestions
Manufacturing implementation path
It is recommended to deploy in three stages:
| Stage | Work content | Cycle |
|---|---|---|
| 1. System docking | Complete the development of the interface between enterprise ERP and Ecode platform | 2-4 weeks |
| 2.Coding migration | Convert existing product codes to Ecode structure | 4-8 weeks |
| 3.Carrier deployment | Production line transformation supports RFID tag writing | 8-12 weeks |
Security and compliance requirements
Must meet the three-level protection specified in GB/T38660-2020:
- Coding security: Prevent malicious tampering
- Transmission security: Use TLS1.2+ encryption
- Resolution Security: Implementing DNSSEC Protection
