Abstract

A method for operating a power management device. The power management device controls a state of a plurality of electronic devices included in a system. The method includes obtaining an activation request to activate at least one electronic device from among the plurality of electronic devices. The method also includes predicting power consumption of the at least one electronic device. The method further includes determining schedule information to activate the at least one electronic device based on the predicted power consumption and current power consumption of the system.

First claim

The invention claimed is:

1. A method of operating a power management device configured to control a state of a plurality of electronic devices included in a system, the method comprising:
obtaining an activation request to activate at least one electronic device from among the plurality of electronic devices;
predicting power consumption of the at least one electronic device;
identifying schedule information to activate the at least one electronic device based in part on a comparison of a threshold to a sum of the predicted power consumption of the at least one electronic device and a current power consumption of the system;
transmitting, to the at least one electronic device, a control signal for activating the at least one electronic device, based on the schedule information;
identifying a first value, wherein the first value is a difference in the current power consumption of the system before the at least one electronic device is activated and after the at least one electronic device is activated;
identifying a second value, wherein the second value is a difference between the first value and the predicted power consumption of the at least one electronic device;
determining whether the second value is within a predetermined range; and
updating the schedule information based on a result of the determination,
wherein the schedule information includes information about predicted times of activation of the at least one electronic device corresponding to the activation request and predicted times of inactivation of active electronic devices among the plurality of electronic devices.

2. The method of claim 1 , wherein, if a sum of the predicted power consumption and the current power consumption of the system is greater than a predetermined threshold power, identifying the schedule information comprises inactivating at least one of the active electronic devices included in the system and activating the at least one electronic device corresponding to the activation request based on at least one of a priority or a usage history of the plurality of electronic devices.

3. The method of claim 2 , wherein identifying the schedule information further comprises:
comparing a priority of the active electronic devices with a priority of the at least one electronic device corresponding to the activation request and inactivating the at least one of the active electronic devices;
activating the at least one electronic device corresponding to the activation request;
predicting a time when the at least one electronic device corresponding to the activation request is inactivated based on a usage history of the at least one electronic device corresponding to the activation request; and
identifying the schedule information to reactivate the inactivated at least one electronic device based on a result of comparing the priorities by using the predicted time.

4. The method of claim 1 , further comprising:
when the system includes at least one other power management device, receiving power consumption-related information of electronic devices managed by the at least one other power management device from the at least one other power management device, and
wherein identifying the schedule information comprises identifying the schedule information based on power consumption of the electronic devices managed by the at least one other power management device, the predicted power consumption, and the current power consumption of the system.

5. The method of claim 1 , further comprising:
comparing a current power consumption of the at least one electronic device and an average power consumption of the at least one electronic device;
identifying occurrence of a defect in the at least one electronic device according to a result of the comparing; and
providing notification information on the occurrence of the defect according to a result of identifying the occurrence of the defect.

6. The method of claim 1 , further comprising:
when the system includes at least one non-intelligent electronic device, obtaining power consumption of the non-intelligent electronic devices,
wherein identifying the schedule information comprises:
identifying the schedule information based on the power consumption of the non-intelligent electronic devices, the predicted power consumption, and the current power consumption of the system.

7. The method of claim 1 , further comprising:
providing a user interface including the schedule information of the at least one electronic device corresponding to the activation request.

8. The method of claim 7 , further comprising:
updating the schedule information in response to a user input through the user interface.

9. A power management device configured to control a state of a plurality of electronic devices included in a system, the power management device comprising:
at least one processor configured to:
obtain an activation request to activate at least one electronic device from among the plurality of electronic devices;
predict power consumption of the at least one electronic device;
identify schedule information to activate the at least one electronic device based in part on a comparison of a threshold to a sum of the predicted power consumption of the at least one electronic device and current power consumption of the system;
control to transmit, to the at least one electronic device, a control signal for activating the at least one electronic device, based on the schedule information;
identify a first value, wherein the first value is a difference in the current power consumption of the system before the at least one electronic device is activated and after the at least one electronic device is activated;
identify a second value, wherein the second value is a difference between the first value and the predicted power consumption of the at least one electronic device;
determine whether the second value is within a predetermined range; and
update the schedule information based on a result of the determination,
wherein the schedule information includes information about predicted times of activation of the at least one electronic device corresponding to the activation request and predicted times of inactivation of active electronic devices among the plurality of electronic devices.

10. The power management device of claim 9 , wherein, if a sum of the predicted power consumption and the current power consumption of the system is greater than a predetermined threshold power, the at least one processor is further configured to inactivate at least one of the active electronic devices included in the system and activate the at least one electronic device corresponding to the activation request based on at least one of a priority or a usage history of the plurality of electronic devices.

11. The power management device of claim 10 , wherein the at least one processor is further configured to:
compare a priority of the active electronic devices with a priority of the at least one electronic device corresponding to the activation request and inactivate the at least one of the active electronic devices;
activate the at least one electronic device corresponding to the activation request;
predict a time when the at least one electronic device corresponding to the activation request is inactivated based on a usage history of the at least one electronic device corresponding to the activation request; and
identify the schedule information to reactivate the inactivated at least one electronic device based on a result of comparing the priorities by using the predicted time.

12. The power management device of claim 9 , further comprising:
