Introduction
Technical background of the standard
This standard is the first special specification for dam safety information management issued by the power industry. It responds to the requirements of the National Energy Administration for the "14th Five-Year Plan" hydropower intelligent construction and solves the problems of information islands and inconsistent interface standards in the existing system. By establishing a unified information classification and coding system, data connectivity throughout the dam's life cycle can be achieved.
Core content analysis
3.1 Information classification system
| Major categories | Number of subcategories | Key attributes | Typical data |
|---|---|---|---|
| Engineering construction category | 6 | Structural parameters | Design flood level, seismic standard |
| Operation and management category | 9 | Dynamic monitoring data | Seepage monitoring, gate operation |
Practical application examples
A hydropower station connected the data of the strong vibration monitor to the management system through a standard interface, triggering the emergency plan linkage mechanism and automatically generating a structural safety assessment report 30 minutes after the earthquake.
System Interface Technical Requirements
4.3 Interface Technology Selection Matrix
| Technology Type | Applicable Scenarios | Transmission Efficiency | Security Level |
|---|---|---|---|
| Restful API | Real-time Monitoring Data | High | AES-256 |
| Web Service | Business Collaboration between Systems | Medium | WS-Security |
4.5 Security Protection Points
- Access control: Four-level permission system based on RBAC model
- Data encryption: Transport layer TLS1.3 + application layer SM4
- Intrusion detection: Deploy AI behavior analysis engine
Implementation suggestions
- Phase-based construction: Prioritize the connection with monitoring automation system
- Metadata governance: Establish a unified coding comparison table
- Performance optimization: Use Kafka message queue to buffer high-concurrency data
Implementation experience of China Three Gorges Corporation
By deploying an interface gateway cluster, the water situation data synchronization time that originally took 2 hours was shortened to 5 minutes, and the flood control dispatch response efficiency was improved by 80%
