Introduction
Analysis of the standard core framework
| System level | Core functions | Key technical indicators |
|---|---|---|
| Management layer | Energy target setting, energy efficiency analysis, optimized scheduling | MTBF≥30000h, data storage≥30 days |
| Analysis layer | Energy consumption prediction, fault diagnosis, energy efficiency benchmarking | Prediction model error≤5%, response time＜2s |
| Perception layer | Data collection, equipment monitoring, secure transmission | Metering accuracy 1.0, AES256 encryption |
Detailed explanation of key technical requirements
1. System architecture design
In the three-layer architecture specified in the standard:
- The management layer needs to establish an energy benchmark (5.4.3), and requires the use of a SCADA system to achieve target decomposition and dynamic adjustment
- The analysis layer should include prediction models, balance models, and optimization models (5.4), and needs to integrate PLC and DCS data
- The perception layer equipment must comply with the GB17167 measurement standard (6.3.1.5), and the communication protocol supports Modbus/DL/T645
2.
| Phase | Work Content | Period |
|---|---|---|
| Infrastructure Construction | Equipment of Measuring Instruments and Deployment of Data Collection Network | 3-6 Months |
| System integration | Three-level system integration, model development | 6-12 months |
| Optimized operation | Energy efficiency benchmarking, continuous improvement | Ongoing |
2. Risk prevention and control
- Network security:It is necessary to configure an industrial firewall (6.3.3.1) and implement VLAN division
- Data security:Use AES encrypted transmission (6.3.2.6) and establish a dual-machine hot standby mechanism
- Operational security:Set three-level control permissions (6.3.4.2) and retain hard switches on site
