Therefore, the improvement direction is gradually adjusted by technicians to improve the control system of the whole machine, so that the system efficiency is improved, and the purposes of energy conservation and emission reduction are achieved.

Analysis and verification show that at present, a lot of factors influencing energy conservation need to be comprehensively considered, and if only a single influence factor is adjusted, the improvement is very slight, even the integral operation is influenced, and the adverse situation is caused. However, the current common energy-saving measures are to adjust through some simple strategies and assistance of manual work, which not only has poor practical effect, but also wastes a large amount of manpower. The system has the advantages that a part of energy-saving systems exist, a complex strategy is adopted, analysis, regulation and control are carried out by combining big data, although a good effect is obtained, the computing capacity of the system is limited, only a small amount of key data can be analyzed, and a good solution cannot be obtained.
