By using mature computer communication technology and software development technology, the advanced energy management system idea and energy management means are integrated into the whole system platform, and the energy meters in the whole region are centralized for flatteningdynamic monitoring, in order to realize real-time automatic collection, monitoring, calculation, dynamic analysis of energy data and the output of energy statistics report forms, and realizethe statistics of output, energy consumption and unit consumption of workshop, team and machine. Timely transmission of energy operation information to the site is to enhance the transparency of information,andhelp mobilize the enthusiasm of all staff for energy-saving and enhance the awareness of energy-saving.

Centralized controller, also known as concentrator, is an embedded device used to collect data from various acquisition terminals or acquisition modules and execute various control commands of the host computer at the same time. It is the hub connecting the main station system and terminal equipment (measuring instruments). The centralized controller has a variety of communication interfaces: RS-232, RS-485, GPRS communication, optical fiber and so on.
