GB/T 38619-2020 in English

Analysis of the core architecture of the standard

GB/T38619-2020 has established a three-layer description system for industrial IoT data collection:

Detailed explanation of key technical elements

1. Data source identification specifications

Adopt a four-level coding system: industry type_industry field_company name_data source (such as: produce_electronic_XX_MES), among which:

• Industry type refers to GB/T4754-2017 classification
• Data sources include PLC, DCS, MES and other 20+ equipment types

2. Data composition model

{ "Data_Group": { "Name": "Draught_fan", "Accessflag": "R", "Data": { "Type": "float", "Unit": "%rh", "Upperlimit": "60%" } } }

Implementation suggestions

1. Data acquisition system transformation: Reconstruct the data dictionary according to the standard and establish a unified ID system
2. Protocol adaptation: Support standard protocol conversion such as OPC UA/MQTT
3. Quality control: Implement data verification mechanisms such as Requisite/Nocompliantmark

Evolution trend analysis

This standard lays the data foundation for the evolution of the Industrial Internet of Things to the digital twin. Subsequent attention should be paid to:

• Special processing of time series data (TSDB)
• Lightweight description in edge computing scenarios
• Cooperation with standards such as GB/T34095-2017
