[Abstract]:The process of converting resources into products by parts processing enterprises will consume a great deal of energy, and at the same time will have a great impact on the environment, such as the emission of a large amount of carbon dioxide. Parts processing is the main process of manufacturing products. It plays an important role in energy saving and emission reduction in manufacturing industry. It is the foundation of low carbon processing in manufacturing industry. This paper makes a deep research on how to calculate the carbon emission effectively in the process of parts processing. A carbon emission assessment model based on process carbon source is established, and the error of process carbon emission is analyzed. To establish the error relationship between the processes, to provide the basis for the origin of carbon footprint anomalies and the improvement of carbon emissions in the whole processing process. Chapter 1, mainly discusses and summarizes the background, purpose and significance of the research. And summarizes and analyzes the domestic and foreign research status of carbon footprint in the process of parts processing. Chapter two analyzes the production and processing process of parts and components, and designs and processes methods based on the information of parts and components. In order to determine the process flow in the process of parts processing, and to discuss the relationship between the characteristic information of parts and the processing methods, the processing methods and the equipment. On the basis of this, the carbon emission characteristics of parts and components processing process are expounded, and the factors influencing the uncertainty of process carbon emissions are analyzed. Based on the analysis and calculation of carbon emissions in parts processing process, a carbon emission assessment model based on process carbon source is proposed. Firstly, the carbon source is constructed on the basis of the carbon emission characteristics of parts processing process. Then the paper analyzes the process characteristics, establishes the four elements of the process characteristics, establishes the calculation rules of the process carbon source, and puts forward the calculation and evaluation model of the material consumption process carbon source, the no-load working procedure carbon source, the load working procedure carbon source, and the carbon emission from the infrastructure. In chapter 4th, the source and classification of the process error are analyzed, and the independent error of the single process is introduced, and the key error source is extracted by the analytic hierarchy process (AHP). Then the error function of carbon emission in multi-process process is expounded. Correlation analysis method is used to discuss the correlation between processes, and regression algorithm is used to verify the fitting function between processes. Chapter 5th, combined with the calculation method of carbon emission in the process of parts processing, takes an electric energy meter manufacturing enterprise as an object. A carbon emission assessment system for parts processing is developed. The overall design of the system is explained from the development idea and structure, and the main function modules of the system are introduced one by one. Chapter 6th summarizes the research contents of the whole paper. The future research work is prospected.
