For example, high-efficiency motors improve the efficiency of the motors and reduce power consumption by optimizing the motor design and manufacturing process. For example, industrial permanent magnet assisted reluctance synchronous motors improve the motor efficiency and power factor through the design of the rotor high salient pole ratio magnetic circuit structure. Industrial heat exchangers such as shell-and-tube enhanced heat exchangers and plate heat exchangers can transfer heat between fluids at different temperatures, realizing the recovery and utilization of heat energy, improving energy utilization efficiency, and more energy conservation and emission reduction equipment;

[0003] When these energy conservation and emission reduction devices are working, they all need to be controlled by a control device for their overall operation to realize the overall operation of the device. However, when the existing industrial energy conservation and emission reduction control devices are in use, their overall control method is relatively fixed, and it is impossible to flexibly and conveniently adjust the working state of the device efficiently for different working scenarios. Thus, it may cause energy consumption and reduce the energy conservation and emission reduction effect during work. Summary of the Invention
