However, for the existing energy efficiency management, on the one hand, the data source is based on monitoring instruments such as electric energy meters installed on site. The data of electric energy meters are minute-level voltage, current, and electric energy data, with few data types and low data resolution. , so that the energy efficiency management system based on this kind of data source lacks the possibility of deep mining and analysis of data; on the other hand, the evaluation of energy consumption is only based on basic energy consumption parameters such as electric energy and thermal energy. And management is one-sided, belongs to the narrow sense of energy efficiency management, does not meet the actual requirements of the user's energy efficiency monitoring and management
