《GB/T 38637.1-2020物联网 感知控制设备接入 第1部分：总体要求》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
Analysis of the core content of the standard
GB/T38637.1-2020, as the basic standard for access to the perception layer of the Internet of Things, establishes the communication framework between perception control devices and the platform. The standard clearly defines for the first time:
- Dual-mode architecture of indirect access (through IoT gateway) and direct access
- Uniform Application Layer Access Protocol (AAP) message format
- Four types of message interaction models (notification/request response/selective response/delayed response)
Access method comparison
| Dimensions | Indirect access | Direct access |
|---|---|---|
| Applicable devices | Non-intelligent/intelligent devices | Only intelligent devices |
| Network topology | LAN+WAN two-level architecture | Direct connection from end to cloud |
| Protocol conversion | Gateway completes protocol conversion | Device natively supports AAP |
Key technologies of AAP protocol
Message structure
The protocol adopts a three-part structure:
- Protocol line: Contains J/1.0 format identifier
- Message header: Must contain message type, serial number, and timestamp
- Message body: Supports JSON/binary encoding
Security mechanism
Standard mandatory requirements:
- TLS/SSL transmission encryption
- Two-way account and password authentication
- Enhanced encryption for sensitive operations
Implementation recommendations
Device selection
Give priority to smart terminals that support MQTT 3.1.1 and above to ensure native AAP compatibility.
Protocol stack development
It is recommended to adopt a layered architecture:
[AAP layer] │ ├── [MQTT adaptation layer] ├── [HTTP adaptation layer] └── [Websocket adaptation layer]
Test verification
Key verifications:
- Message integrity in selective response mode
- TLS1.2+ encryption performance
- Gateway concurrent access capability
