Introduction
Analysis of the standard core framework
| Intelligence level | Key technical features | Typical application scenarios |
|---|---|---|
| Ontology intelligence (I1) | Basic parameter configuration, local data storage, functional self-test | Traditional industrial field independent instruments |
| Basic intelligence (I2) | Two-way communication, firmware upgrade, time synchronization | DCS system basic layer equipment |
| System intelligence (I3) | Remote configuration, interoperation, process diagnosis | Smart factory central control system |
| Autonomous Intelligence (I4) | AI Algorithms, Edge Computing, Predictive Maintenance | Industrial Internet Edge Nodes |
Detailed Explanation of Key Technical Requirements
1. Communication Protocol Matrix
The standard requires that the instrument support at least one of the following three types of communication protocols:
- Industrial Bus: HART/Modbus/PROFIBUS, etc.
- Industrial Ethernet: EtherCAT/PROFINET, etc.
- Industrial Wireless: WirelessHART/5G, etc.
Typical Case: A Smart pressure transmitter achieves a 99.5% communication success rate by integrating HART+WirelessHART dual protocols
2. Diagnostic capability classification requirements
| Diagnostic type | I2 level requirements | I4 level requirements |
|---|---|---|
| Hardware diagnosis | ≥8 basic diagnosis items | ≥20 items + prediction model |
| Process diagnosis | Basic anomaly detection | Pattern recognition + trend prediction |
| Accuracy | No clear requirements | ≥90% |
Recommendations for the implementation of the standard
Enterprise upgrade path planning
- Current situation assessment: Conduct intelligent level diagnosis according to Appendix A of the standard
- Gap analysis: Focus on checking core indicators such as communication interface and diagnostic function
- Step-by-step implementation: It is recommended to follow the step-by-step upgrade path of I2→I3→I4
A valve manufacturer achieved the leap from I2 to I3 within 6 months by adding FDT/DTM interface and friction torque analysis algorithm
Key points of testing and certification
- Third-party test report is valid for ≤3 years
- The autonomous intelligence level requires the provision of algorithm training data sets and verification reports
- Key items: quantitative indicators such as communication success rate and diagnosis accuracy
