Real time power monitor and management system

1. A power monitor and management system comprising:

an automatic modulation device including multiple frequency converters electrically connected multiple transformers, respectively, a first power supply connected to the frequency converters and a second power supply connected to the transformers;

a monitoring device;

multiple USP (uninterrupted power system) modules; and

an eCAN BUS (enhanced controller area network) connected to the monitoring device and the UPS modules to enable the monitoring device to communicate with the UPS modules, wherein the automatic modulation device determines a dominating module of the UPS modules according to registration sequences of the UPS modules logging on the power monitor and management system and other UPS modules becoming subordinating modules, and adjusts an overall power output in accordance with a number of the UPS modules, and

wherein load variation and power output are monitored by the dominating module and a monitor result is regularly reported back to the monitoring device to modulate power output between the dominating module and the subordinating modules in real-time.

2. The system as claimed in claim 1 , wherein the monitoring device sends out a command to synchronize a clock signal between the dominating module and the subordinating modules.

3. The system as claimed in claim 2 , wherein the eCAN bus receives a command and sends out decode command to the modules to enable the modules to operate according to the decoded command.

4. The system as claimed in claim 3 , wherein the eCAN bus sends out an executable command to update the monitoring device.

5. The system as claimed in claim 1 , wherein the first power supply is a DC power supply and the second power supply is an AC power supply.
