Introduction
Interpretation of the core content of the standard
As a programmatic document for the application of RFID technology in the field of intelligent manufacturing, this standard systematically stipulates the technical requirements of the radio frequency identification system in industrial environments for the first time. Its technical framework covers three core components: RFID tags, readers and middleware, forming a complete intelligent manufacturing data collection system.
System architecture requirements
| Components | Core functions | Key technical indicators |
|---|---|---|
| RFID tag | Production factor identification, data storage | HF/UHF dual-frequency support, anti-metal interference, compliance with GB/T36365 |
| Reader/writer | Data collection, command issuance | Multi-tag processing capability, industrial bus access, compliance with GB/T34996 |
| Middleware | Data preprocessing, system docking | Support GB/T34047 interface, multi-reader management |
Key technical specifications
Tag technical requirements
The standard clearly requires that tags must have the ability to uniquely identify production factors. Typical application scenarios include:
- Employee badge identification (anti-metal interference design)
- Work-in-progress tracking (high temperature environment tolerance)
- Equipment asset management (long-life battery design)
Reader performance indicators
Special provisions for smart manufacturing environments:
- Industrial protection level (above IP65)
- Multi-reader collaborative anti-collision mechanism
- Support PROFINET/Modbus and other industrial protocols
Implementation recommendations
Application practices in automobile manufacturing scenarios show that:
- Frequency band selection: UHF band is more suitable for long-distance identification of assembly lines
- Tag installation: Metal parts require special packaging tags
- System integration: Connect with MES system through OPC UA
The standard places special emphasis on electromagnetic compatibility testing requirements, and it is recommended to conduct on-site field strength mapping before implementation.
