Engineering Contradiction Analysis
1Measurement precision
If traditional emission evaluation methods are used, then the evaluation process is simple, but the evaluation results lack precision and cannot reflect actual emission situations accurately
Solution Approach 1:
The patent segments the emission evaluation system into multiple independent modules: data acquisition module, data processing module, emission calculation module, and reporting module. Each module handles specific tasks independently, improving measurement precision through specialized processing while managing complexity through modular architecture. The system divides emission sources into different categories (coke oven, sintering, casting, etc.) and processes each separately.
Solution Approach 2:
The patent introduces an intermediary data processing layer between raw emission data and final evaluation results. This intermediary layer includes emission factor databases, calculation models, and verification mechanisms that transform raw data into accurate emission assessments. The intermediary processing ensures precision while maintaining system manageability through standardized transformation rules.
2Reliability
If comprehensive data collection is implemented, then evaluation accuracy improves, but data security risks and system complexity increase
Solution Approach 1:
The patent implements local quality control by applying different security and access levels to different data elements within the system. Sensitive emission data, enterprise information, and calculation parameters are protected with appropriate access controls and encryption methods tailored to their specific security requirements. This approach ensures high reliability through comprehensive data protection while managing security complexity through differentiated protection strategies.
Solution Approach 2:
The patent incorporates beforehand cushioning measures by implementing pre-established security protocols, data validation rules, and error handling mechanisms. The system includes built-in verification of data authenticity, completeness checks, and security authentication before data processing. These preventive measures ensure reliability while managing security risks through automated protection mechanisms.

AI summary
Provided in the present disclosure are a carbon emission evaluation model, evaluation method and evaluation system for a long-procedure iron and steel enterprise. In the present disclosure, for iron and steel enterprise characterized by a long blast furnace-converter procedure, during carbon emission evaluation, the carbon emission evaluation of levels of the iron and steel enterprise depending on the coupling relationship between a material flow, an energy flow and a carbon flow, and process units connected thereto. In view of the coupling relationship between the material flow and the energy flow and the characteristic of the carbon flow being inseparable from the material flow and the energy flow during an iron and steel production process, a material flow-energy flow-carbon flow analysis model is invented, such that when a parameter of any link changes, the determination of other production processes affected by the link is fully realized. By means of a determined chain reaction, the effect of a change in a certain parameter during the whole production process or between links can be accurately evaluated, a defect in the aspect of repeated calculation or missing calculation is overcome, and the accurate evaluation of carbon emission during the production process in which there is a chain reaction when measures are implemented in the iron and steel enterprise is realized.
