GB/T 41780.2-2024 in English

Overview of IoT edge computing data management requirements

GB/T 41780.2—2024 "IoT edge computing Part 2: Data management requirements" is an important standard in China's IoT field, which mainly regulates the data management functions of edge computing nodes (such as IoT terminals, edge gateways, edge controllers and edge computing servers).

Background of standard formulation

With the rapid development of IoT technology, edge computing, as an important part of IoT, has a direct impact on the efficiency and reliability of the system through its data management capabilities. This standard aims to unify the data management function framework of IoT edge computing, clarify the functional requirements of various types of edge nodes, and ensure data security.

Technology Evolution Analysis

From a technical perspective, edge computing is developing in the direction of intelligence, distribution and efficiency:

• Data processing capabilities are gradually enhanced to support complex logic control;
• Communication protocols are diversified (such as TCP, UDP, MQTT, etc.) to improve data transmission efficiency;
• Data security mechanisms are continuously strengthened to ensure the protection of sensitive data.

Edge computing data management function framework

According to the standard requirements, the data management function framework of IoT edge computing includes the following core parts:

Interpretation of data collection requirements

Data collection of IoT terminals must meet the following key requirements:

• Accuracy and cycle control: Ensure the accuracy and real-time nature of the collected data.
• Multi-channel support: Support the access of multiple sensors and communication interfaces.
• Timestamp tag: Add time information to each data point for subsequent analysis.

Interpretation of data security requirements

Data security is the core concern of edge computing. The standard clearly stipulates:

• Classification and grading protection: Implement multi-level protection according to the importance of data.
• Transmission encryption: Use protocols such as HTTPS and MQTT to ensure data transmission security.
• Access control: Based on the principle of least authorization, strictly limit data access rights.

Implementation suggestions

To ensure the effective implementation of the standard, it is recommended to take the following measures:

1. Node selection and deployment optimization: Rationally configure edge computing nodes according to actual needs.
2. Data quality management mechanism: Establish a complete data quality assessment and monitoring system.
3. Security policy formulation: Combine standard requirements and customize data security solutions.
