Therefore, the application of unit centralized control technology around the three parts of the electromechanical furnace system layout, system principle, fixed value parameters, operation mode, logic and operation procedures control can improve the power generation stability of thermal power plants. Based on this, this paper first summarizes the concept of centralized control of thermal power plants and generating units, and then focuses on the principles and technical solutions of the application of centralized control technology of generating units.展开更多

This paper mainly discusses how to automatically identify the train state by ultrasonic ranging technology, and upload the train state information to the centralized control unit through PLC, so as to automatically control the lighting circuit in the tunnel to turn on or off, thus achieving the purposes of energy saving, low carbon and environmental protection, and prolonging the service life of equipment.展开更多
