| 摘要 |
The present invention relates to an energy management system for a whole factory or a building comprising: an energy consumption collecting unit for detecting energy consumption of each equipment in real time from various kinds of equipment consuming energy; an energy management server unit for calculating and storing energy consumption of various kinds of equipment for each system and entire energy consumption by adding the energy consumption of each equipment transferred from the energy consumption collecting unit; a monitor unit for displaying a graph, text, or number which can be visually recognized according to the energy consumption for each system and the entire energy consumption calculated by the energy management server unit and data or control command transferred by the energy management server; and an input unit for selecting a GUI element displayed on the monitor unit or inputting data or command, wherein a graph displayed on the monitor unit displays the energy consumption of each system by divaricating the entire supplied energy by sizes according to their proportions, thereby, allowing users to visually identify an entire energy flow of the equipment for each system. [Reference numerals] (AA) Monthly trend; (BB) Increase and decrease of each system; (CC) Change in a component ratio; (DD) Basis for detailed analysis by eliciting main energy consumption |
