Equipment power management system
First Claim
1. An equipment power management system comprising:
- a plurality of electrical devices having multiple operational states different from each other in power consumption of a commercial power source, each electrical device operable in an operational state of the multiple operational states; and
a control device including;
a comparator to compare a receiving power amount of the plurality of electrical devices to a first threshold value and to a second threshold value lower than or equal to the first threshold value;
a switch to switch the operational states of one or more electrical devices to that of a smaller power consumption in ascending order from the electrical device of a lowest priority when the comparator determines that the receiving power amount exceeds the first threshold value until the comparator determines that the receiving power amount falls below the second threshold.

Abstract
An equipment power management system in accordance with the present invention has a plurality of electrical devices and a control device. The electrical devices can operate in any one of multiple operational states different from each other in power consumption of a commercial power source. The control device switches the operational state of an electrical device to that of a smaller power consumption of the commercial power source in ascending order from the electrical device of the lowest priority when a receiving power amount of the whole equipment including the plurality of electrical devices exceeds a first threshold value until the receiving power amount falls below a second threshold value which is lower than or equal to the first threshold value.

17. A control device comprising:
-
a communication interface unit to communicate with a plurality of electrical devices having multiple operational states different from each other in power consumption of a commercial power source, each electrical device operable in an operation state of the multiple operational states; and a power reduction control unit including; a comparator to compare a receiving power amount of the plurality of electrical devices to a first threshold value and to a second threshold value lower than or equal to the first threshold value; a switch to switch the operational states of one or more electrical devices to that of a smaller power consumption in ascending order from the electrical device of a lowest priority when the comparator determines that the receiving power amount exceeds the first threshold value until the comparator determines that the receiving power amount falls below the second threshold.
