《GB/T 5094.1-2018工业系统、装置与设备以及工业产品 结构原则与参照代号 第1部分：基本规则》由TC27（全国电气信息结构、文件编制和图形符号标准化技术委员会）归口，主管部门为国家标准化管理委员会。
Introduction
Analysis of the core framework of the standard
| Version comparison dimensions | GB/T 5094.1-2002 | GB/T 5094.1-2018 |
|---|---|---|
| Terminology system | 15 basic terms | 4 new key terms (process/component/location/identifier) |
| Chapter structure | 8 chapters + 4 appendices | 10 chapters + 8 appendices, new reference code description and marking chapter |
| Structural principles | Mainly unilateral structure | Multi-dimensional structural integration (functional/product/location coordination) |
Evolution of key technologies
Taking substation control system as an example, the structural changes before and after the implementation of the standard are:
- Functional surface structure: =P1 (protection function) →=M1 (measurement function)
- Product surface structure: -Q1 (circuit breaker) →-T1 (transformer)
- Location surface structure: +A1 (distribution room) →+B2 (control cabinet)
Three core structural systems
1. Functional surface structure
Prefix =, example: =C3 (cooling system function), applicable to:
- Process flow chart design
- System function decomposition
2. Product surface structure
Prefix -, example: -M5 (motor component), advantages include:
- Bill of materials (BOM) management
- Supply chain collaboration
3. Location surface structure
Prefix +, example: +F12 (second floor of factory building), implementation points:
- Compatible with ISO 4157 building code
- Support 3D coordinate positioning
Implementation and application suggestions
- Multi-system integration: It is recommended to adopt PDMS and other 3D design platforms to achieve structure mapping
- Data governance: Establish an enterprise-level reference code master database
- Life cycle management: Embed PLM system from the design stage
