Carbon emission metering system combined with factory business digital model

The invention relates to the technical field of carbon metering, in particular to a carbon emission metering system combined with a factory business digital model, which comprises a digital model, a sensor, a monitoring device, a data processing module and a data output module, and comprises the following metering steps: S1, establishing the factory business digital model, sensors and monitoring equipment are placed in a factory, initial data of energy consumption and waste gas components of all links in the factory are collected, a digital full-quantity database is formed, and the data are transmitted into a data processing module. According to the method, indirect carbon emission in a factory business operation process can be comprehensively considered by combining a factory business digital model, so that the carbon emission condition of a factory is reflected more accurately; the carbon emission is displayed in a visual form, so that a user can be helped to understand the carbon emission condition more vi
