《GB/T 33474-2016物联网 参考体系结构》由TC28（全国信息技术标准化技术委员会）归口，TC28SC41（全国信息技术标准化技术委员会物联网分会）执行，主管部门为国家标准化管理委员会。
Introduction
Overview of IoT Reference Architecture
Core Architecture and Technical Framework
| Dimension | Entity Category | Interface Type |
|---|---|---|
| System Architecture | Combined 6 major business domains (user/perception control, etc.) | 21 types of SRA interfaces |
| Communication Architecture | Support wireless cellular/private networks | 17 types of CRA communication interfaces |
| Information Architecture | Establish a data hierarchical processing system | Data encryption and QoS guarantee |
Key entity interaction model
Intelligent equipment interface system realizes the control closed loop through the SRAT05/06 interface with the intelligent gateway.
- Execution control delay: The overall jitter from the sensor network node (CRA01) to the user system service response is less than 500ms
- Data processing service Multiple edge nodes implement federated learning preprocessing through the IRS interface
Implementation recommendations and evolution analysis
- Security enhancement: The new version strengthens the multi-factor authentication mechanism of the operation and maintenance control domain
- Interoperability: The system reference architecture adds resource exchange domain external service docking specifications
| Key static parameter comparison (industrial grade VS consumer grade) | ||
|---|---|---|
| Indicator items | Industrial Internet of Things | Smart Home System |
| Terminal Operating Environment | -40~85℃ | 0~55℃ |
| Encryption Certification Level | AES256+PME | WPA3 Basic Protection |
Model Access Certification Recommendations
- Core nodes must pass GA/T 1363-2017 safety certification
- Gateway equipment must obtain IP65 protection grade certificate
