[0002] The energy consumption of equipment in the production workshop is directly related to production efficiency, cost control and resource utilization efficiency. The equipment in the production workshop usually includes various mechanical equipment, electronic equipment, lighting equipment, etc. By comprehensively monitoring the energy consumption status of the equipment in the production workshop, abnormalities can be discovered in time, equipment operation plans can be optimized, energy utilization efficiency can be improved, and production costs can be reduced. At the same time, by formulating effective energy-saving measures, the goal of reducing energy consumption and improving production efficiency can also be achieved.

[0003] Under the current technical background, the energy consumption of equipment in the production workshop usually only counts the overall power consumption of the production workshop. In the work of troubleshooting equipment with abnormal energy consumption, there is a lack of comprehensive consideration of factors such as the service life and continuous operation of the production equipment, which has an adverse impact on the efficiency of energy consumption optimization. Therefore, how to achieve intelligent processing of production energy consumption in the production workshop on the basis of ensuring the efficiency of abnormal elimination is the current problem; To this end, we propose a method and system for optimizing production energy consumption in a production workshop. Summary of the invention

The values ​​of r include 1, 2, and 3. r=1 corresponds to gas consumption, r=2 corresponds to electricity consumption, and r=3 corresponds to steam consumption and water vapor consumption. The equipment energy efficiency value NXi of the production equipment is calculated according to the formula. The specific formula is as follows: ; The equipment energy efficiency value of the production equipment is compared with the energy efficiency definition interval. If the equipment energy efficiency value of the production equipment belongs to the first energy efficiency definition interval, the energy efficiency level of the production equipment is judged to be unqualified; if the equipment energy efficiency value of the production equipment belongs to the second energy efficiency definition interval, the energy efficiency level of the production equipment is judged to be qualified; wherein, the values ​​of the first energy efficiency definition interval and the second energy efficiency definition interval are both greater than zero, and the values ​​of the first energy efficiency definition interval are both less than the values ​​of the second energy efficiency definition interval.
