[0053] In order to more clearly understand the purpose, technical solutions and advantages of the present application, the present application is described and illustrated below in conjunction with the accompanying drawings and embodiments.

[0054] Reference Figure 1 As shown, in this embodiment, a method for calculating carbon emissions in an electronic equipment recycling process is provided, and the method comprises steps S110 and S120.

[0057] For example, when collecting energy consumption data during the production and processing of an enterprise, the difficulty of data collection during the production and processing of the enterprise is divided into simple stable working conditions, sub-stable working conditions, and mixed working conditions. Among them, the simple stable working condition is a production unit with a relatively single energy use and a stable single process duration. The energy consumption fluctuations in the process of processing a single identical component are stable, and direct carbon emission data can be obtained by installing relevant simple monitoring devices (such as robot handling and stacking processes); the sub-stable working condition is a production unit with a clear type of energy use and a relatively stable single process duration. There are small fluctuations in the energy consumption in the process of processing a single identical component. Direct carbon emission data can be obtained by installing a dynamic energy consumption collection device and field sampling detection (such as manual disassembly or welding of the same component); the mixed working condition is a production unit with a relatively unstable single process duration. The energy consumption for processing a single identical component varies greatly. The data is obtained by installing precise energy consumption collection devices, work logs, reports and multiple field surveys. For data that are difficult to monitor directly, they are estimated through thermodynamic or kinetic related equations (empirical formulas), and the energy consumption curve of the production and processing parts is fitted according to the real-time energy consumption collection through mathematical induction to obtain indirect carbon emission data. The corresponding relevant carbon emission factors are queried through policies and industry specifications, and these data are integrated and updated to the carbon-related database.
