Here, activating the electronic device may change the state of at least one electronic device in an inactive state to an active state.

The state of the electronic device may be classified into G0 (working), G1 (standby mode), G2 (soft shutdown), and G3 (mechanical shutdown) states according to ACPI (Advanced Configuration and Power Interface (ACPI)) standards. The active state may correspond to the G0 state and the inactive state may correspond to the G1, G2 or G3 state, respectively.

In detail, the active state may include a state in which a switch of the electronic device is turned on or a state G0 in which some function of the electronic device is being performed.

In addition, the activation request obtained by the power management device 100 may be obtained from the electronic devices 102 included in the power management device 100 or the system 103. For example, the activation request may be a control signal (or data) transmitted from one electronic device to the power management device 100 based on a user input input to one of the electronic devices 102. Can be. Alternatively, the activation request may be obtained through a user interface provided by the power management apparatus 100.

Alternatively, the power management device 100 may obtain an activation request from an electronic device (not shown) outside the system 103. Here, the electronic device outside the system 103 may be an electronic device that is pre-registered in the power management device 100, and may be a device that provides a user interface for controlling the power management device 100. For example, the external electronic device may transmit an activation request to the power management device 100 based on a user input input through the user interface.

In operation 204, the power management apparatus 100 At least one Predict the power consumption of the electronic device. Here, the at least one electronic device may be at least one electronic device corresponding to the activation request.

According to an embodiment of the present disclosure, the power management device 100 may estimate the power consumption of the electronic device corresponding to the activation request based on the usage history of the electronic device. Hereinafter, for convenience of description, the power consumption predicted by the power management apparatus 100 is referred to as 'predicted power consumption'.

According to an embodiment, the power management apparatus 100 may monitor power consumption and power usage time of the electronic devices 102. For example, the power management apparatus 100 may monitor a current power consumption of the system 103, a current power consumption for each electronic device, a peak power consumption, a time when the electronic device is activated (or deactivated), and the like. In addition, the power management device 100 may obtain the usage history of the electronic devices 102 by analyzing the monitored information. For example, the power management device 100 analyzes the monitored information to accumulate power consumption, average power consumption, power consumption per hour, recent usage time, average usage time, and cumulative usage time of the system and the electronic device. It is possible to obtain a usage history including information on the back. In addition, the power management apparatus 100 may store and / or manage information on the obtained usage history.

The power management device 100 may determine the estimated power consumption of the electronic device from which the activation request is obtained, using the average power consumption and the average usage time of the electronic device for a predetermined period of time. For example, when an activation request for the display device is obtained, the power management device 100 may determine the predicted power consumption of the display device using the average power consumption and the average usage time for one week of the display device.

Meanwhile, in the above description, the power management apparatus 100 monitors power consumption and power usage time of the electronic devices 102, but the present disclosure is not limited thereto. For example, the power management device 100 may receive the power consumption and the power usage time monitored by the power supply, the smart outlet, or the electronic devices 102.

In addition, according to an embodiment, the power management apparatus 100 may determine the predicted power consumption amount of the electronic device by using a look-up table stored inside or outside the power management apparatus 100. Here, the look-up table may include identification values, average power consumption, average usage time, and the like of the electronic devices 102. In addition, the lookup table may be updated at regular time intervals (eg, 24 hour intervals, weekly intervals, etc.). Therefore, when the activation request is obtained, the power management device 100 may determine a predicted power consumption amount of the electronic device corresponding to the activation request by accessing the lookup table.

Alternatively, the power management device 100 may receive the estimated power consumption of the electronic device from the electronic device corresponding to the activation request. For example, the activation request received by the power management device 100 from the display device may include a predicted power consumption value of the display device.

Meanwhile, the power management apparatus 100 may update the predicted power consumption whenever the activation request is obtained. Therefore, the updated predicted power consumption may exclude the predicted power consumption of the electronic device that is pre-activated at the update time.

If the power consumption of the system 103 exceeds the amount of power provided from the outside, the power supply may cut off the power supplied to the system 103. Accordingly, the power management apparatus 100 may control an operation of controlling a state (eg, an active state or an inactive state) of an electronic device that has sent an activation or deactivation request in order to prevent the power supply from blocking power supply. Can be done.

In operation 206, the power management apparatus 100 determines schedule information for activating at least one electronic device based on the predicted power consumption and the current power consumption of the system 103. Here, the at least one electronic device may be at least one electronic device corresponding to the activation request. In addition, the current power consumption of the system 103 may be a real time power consumption consumed by the electronic devices 102 of the system 103.

In addition, the schedule information may include at least one of information on the order of activating the electronic device corresponding to the activation request and information on time.

According to an embodiment, the power management apparatus 100 may compare the total power consumption, which is the sum of the current power consumption and the predicted power consumption of the system 103, with the threshold power amount. In this case, the threshold power amount may be determined according to at least one of a maximum acceptable power amount and a safety index indicating the maximum amount of power supplied to the system 103 from the outside.

When the total power consumption of the system 103 exceeds the threshold power amount, the power management device 100 is in an active state included in the system 103 based on at least one of the priority and usage history of the electronic devices 102. Schedule information for deactivating the electronic device and activating the electronic device corresponding to the activation request.

For example, the power management device 100 compares the priority of the first electronic device corresponding to the activation request with the priority of the electronic devices in the active state, and among the electronic devices in the active state, the priority of the first electronic device. The schedule information for deactivating the second electronic device lower than the rank and activating the first electronic device may be determined. If the priority of the electronic devices in the active state is the same as the priority of the first electronic device, the power management device 100 uses the average usage among the electronic devices in the active state based on the usage history of the electronic devices in the active state. The third electronic device having the longest time may be deactivated and schedule information for activating the first electronic device may be determined.

Or, when an activation request is obtained from two or more electronic devices having the same priority, the power management device 100 schedules to first activate one of the electronic devices according to a usage history of the electronic devices for which the activation request is obtained. Information can be determined. For example, the power management apparatus 100 may determine schedule information for activating the electronic device having the lowest average power consumption first based on the average power consumption of each electronic device. Alternatively, when an activation request is obtained from two or more electronic devices having the same priority, the power management device 100 schedules to first activate the electronic device having the shortest average use time based on the average use time of the electronic devices. Information can be determined. A method of determining the schedule information by the power management apparatus 100 will be described later in detail with reference to FIGS. 3 to 5.

In addition, the power management device 100 may control a state (eg, an active state or an inactive state) of the electronic devices 102 of the system 103 based on the schedule information. According to an embodiment, the power management apparatus 100 may control the states of the electronic devices 102 by transmitting a control signal to the electronic devices 102 based on the schedule information. Alternatively, the power management device 100 may control the states of the electronic devices 102 by transmitting a control signal to the smart outlet or the power supply device based on the schedule information.

According to an embodiment, the power management apparatus 100 may provide a user interface including schedule information. In addition, the power management apparatus 100 may update, change, and delete schedule information in response to a user input through a user interface.

Meanwhile, when the total power consumption of the system 103 is less than or equal to the threshold power of the system 103, the power management device 100 may transmit a control signal for activating a state of the electronic device corresponding to the activation request to the electronic device.

Meanwhile, according to an embodiment, when the system 103 includes at least one non-intelligent electronic device, the power management device 100 may use a non-intelligent electronic device using a control device such as a switch connected to a smart outlet or a power device. You can control the state of. Here, controlling the state of the non-intelligent electronic device may be that the power management device 100 controls the amount of power supplied to the non-intelligent electronic devices by using the control device. In this case, the power management apparatus 100 may cut off or supply power to the non-intelligent electronic device according to the schedule information by performing the operations of steps 202 to 206.

Alternatively, when the power management device 100 does not include a control device for controlling the power supplied to the non-intelligent electronic devices, the power management device 100 activates the non-intelligent electronic devices. Can be assumed. Accordingly, the power management apparatus 100 may determine schedule information based on the estimated power consumption, the current power consumption of the system 103, and the average power consumption of the non-intelligent electronic devices in step 206. Meanwhile, the average power consumption of the non-intelligent electronic devices may be monitored by the power management device 100. As such, the power management apparatus 100 may prevent the power consumption of the system 103 from exceeding the threshold power amount even when the system 103 cannot directly control the state of the electronic device.

3 is a flowchart illustrating a method of determining schedule information based on a priority of a power management apparatus according to an exemplary embodiment.

Referring to FIG. 3, in operation 302, the power management apparatus 100 may determine whether the total power consumption exceeds a threshold power amount. Here, the total power consumption may be the sum of the predicted power consumption of the electronic device corresponding to the activation request and the current power consumption of the system 103.

According to an embodiment, the power management apparatus 100 may determine the threshold power amount based on at least one of the maximum power capacity and the safety index of the system 103. The maximum amount of power received may be obtained from a power supply device or an external server (eg, a server operated by the power management corporation). In addition, the safety index may be a default value set in the power management device 100 or a value determined by a user input.

For example, when the safety index is 10%, the power management device 100 may determine 90% of the maximum amount of power received by the system 103 as the threshold power amount. According to one embodiment, when the power supply includes a protection device such as a circuit breaker or a fuse, the maximum amount of received power may be a value at which the function of the protection device is activated.

According to an embodiment, the power management apparatus 100 may determine the threshold power amount according to a user input. For example, the power management apparatus 100 may provide a user interface for determining the threshold power amount. Alternatively, the power management device 100 may receive a threshold power amount determined by a user input input from another electronic device.

According to an embodiment, the power management apparatus 100 may compare the total power consumption with the threshold power and determine whether the total power consumption exceeds the threshold power.

If the total power consumption exceeds the threshold power amount, in step 304, the power management device 100 may compare the priority of the electronic devices in the active state with the priority of the electronic device corresponding to the activation request.

According to an embodiment of the present disclosure, the power management apparatus 100 may assign the priorities to the electronic devices 102 included in the system 103 based on a predetermined criterion. For example, the power management device 100 may include the characteristics of the system 103, the acquisition frequency of activation requests for each electronic device, the preference of the electronic device according to a user input, the characteristics of the electronic device, the function of the electronic device, and the average of the electronic devices. The priority may be allocated according to the power consumption amount or a combination thereof. The characteristics of the system may include information about the environment (eg, home, kitchen, company, etc.) where the system is located. In addition, the characteristic of the electronic device may include information on whether the activated electronic device may be changed to an inactive state while performing a predetermined task.

For example, the power management device 100 may assign priority to the electronic devices 102 according to the characteristics of the system 103. If the system 103 is located at home, the power management apparatus 100 may assign a high priority (eg, a first priority) to home appliances such as a dishwasher or a washing machine. On the other hand, when the system 103 is located in an office, the power management apparatus 100 may assign a low priority (eg, a tenth rank) to the home appliance.

Alternatively, the power management device 100 may assign a priority according to the functions of the electronic devices 102. For example, since the dishwasher and the washing machine have the same washing function, the power management device 100 may assign the same priority (for example, the third rank) to the dishwasher and the washing machine.

According to an embodiment, the power management apparatus 100 may compare the priorities of the electronic devices in the active state with the priorities of the electronic devices corresponding to the activation request, based on the predetermined priority. For example, the power management apparatus 100 may compare the priority of the washing machine in the active state with the priority of the display device, which is an electronic device corresponding to the activation request.

In operation 306, the power management apparatus 100 may determine schedule information for activating an electronic device corresponding to the activation request, based on the result of the priority comparison in operation 304.

According to an embodiment, if the priority of the second electronic device in the active state is lower than that of the first electronic device corresponding to the activation request, the power management device 100 selects the second electronic device having a lower priority. Schedule information for deactivation may be determined. For example, when the priority of the display device, which is an electronic device corresponding to the activation request, is 'first priority', and the priority of the active washing machine is 'third priority', the power management device 100 may turn on the washing machine. Deactivation and schedule information for activating the display device may be determined.

Meanwhile, the power management apparatus 100 may update schedule information whenever a new activation request is obtained. For example, the power management device 100 may obtain an activation request for a display device assigned a higher priority than the dishwasher while the activation request of the dishwasher is waiting according to the schedule information. In this case, the power management apparatus 100 may update the schedule information to determine schedule information for activating the display device first.

Meanwhile, when the total power consumption is less than or equal to the threshold power in step 302, the power management device 100 may transmit a control signal for sequentially activating electronic devices corresponding to the activation request according to priority.

As described above, the power management apparatus 100 may determine schedule information for efficiently performing a function of an electronic device having a high priority without exceeding the maximum amount of power received by the system 103.

In operation 402, the power management apparatus 100 may determine whether the total power consumption of the system 103 exceeds a threshold power amount. Since the embodiment of step 302 of FIG. 3 may be applied to step 402, a detailed description thereof will be omitted.

When the total power consumption exceeds the threshold power amount, in step 404, the power management device 100 may predict the time when the electronic devices in the active state are deactivated based on the usage history of the electronic devices in the active state.

As described above with reference to FIG. 2, the usage history may include an average usage time, an average power consumption amount, and a recent usage start time.

The power management device 100 may obtain relationship information between the electronic devices, state information of the electronic device for each time, time information when the electronic device is activated, and the like based on the usage history of the electronic devices.

According to an embodiment of the present disclosure, the power management device 100 may predict a time for deactivating an electronic device that is in an active state, based on state information of the electronic device for each time. For example, the power management apparatus 100 may predict that the washing machine in the active state will be deactivated at 11 pm based on the state information of the washing machine for each hour.

Alternatively, the power management device 100 may estimate a time when the electronic device in an active state is deactivated based on the average usage time and the latest usage start time for each electronic device. For example, the power management device 100 is based on the average usage time of the cleaner (eg, 30 minutes) and the latest usage start time (eg, 10:40 pm), so that the active washing machine is in the afternoon. We can expect it to deactivate at 11:20.

Information can be determined. The power management device 100 may select one electronic device from among the electronic devices in the active state by comparing the current time with the time when the electronic devices in the active state are expected to be deactivated.

For example, when the activation request is obtained from the display device at 10:50, the power management device 100 may compare the current time (that is, 10:50) with the estimated time when the washing machine and the cleaner in the active state are deactivated. Can be compared. In addition, the power management apparatus 100 may determine schedule information for deactivating the washing machine at 11 pm and activating the display apparatus at 11 pm. Also, according to the schedule information, the power management apparatus 100 may transmit a control signal for changing the washing machine to an inactive state to the washing machine at 11 o'clock, and transmit a control signal for changing the display device to the active state to the display device.

Meanwhile, the power management device 100 may provide a user interface including schedule information indicating that the washing machine is deactivated at 11 o'clock and the display device is activated at 11 o'clock. In this case, the power management device 100 may change the schedule information to deactivate the washing machine at 11:10 and activate the display device at 11:10 in response to a user input to the user interface.

In operation 402, when the total power consumption is less than or equal to the threshold power amount, the power management device 100 may transmit a control signal for activating a state of the electronic device corresponding to the activation request to the electronic device.

On the other hand, the power management device 100 has been described as determining the schedule information by estimating the time when the electronic device in the active state is deactivated, but is not limited thereto. According to an embodiment, the power management apparatus 100 may determine schedule information based on a relationship between an electronic device in an active state and the electronic device corresponding to the activation request.

For example, based on the relationship between the lighting device and the security device, the power management device 100 may determine schedule information for deactivating an active lighting device and activating the security device when an activation request for the security device is obtained. have.

In addition, the power management device 100 may deactivate the second electronic device having the lowest priority among the extracted electronic devices. For example, the power management device 100 may generate a control signal for deactivating the second electronic device and transmit the generated control signal to the second electronic device. For example, when an activation request for the display device is obtained, the power management device 100 may deactivate the cleaner having a lower priority than the display device among the electronic devices in the active state.

In operation 504, the power management apparatus 100 may transmit a control signal for activating the electronic device corresponding to the activation request.

According to an embodiment, the power management device 100 may generate a control signal for activating the first electronic device corresponding to the activation request, and transmit the generated control signal to the first electronic device. For example, the power management device 100 may transmit an activation control signal to the display device.

In operation 506, the power management device 100 may estimate a time when the electronic device corresponding to the activation request is deactivated based on the usage history of the electronic device corresponding to the activation request. For example, the power management device 100 may predict a time at which the electronic device is deactivated based on state information of the electronic device for each time, an average usage time for each electronic device, or a recent usage start time.

For example, the power management device 100 may predict that the display device will be deactivated after a predetermined time (or a specific time) based on the usage time information for each electronic device of the display device.

In operation 508, the power management apparatus 100 may determine schedule information for reactivating the deactivated electronic device according to the priority comparison result based on the information about the estimated time.

According to an embodiment, the power management apparatus 100 may determine schedule information for reactivating the electronic device deactivated in operation 502 at the estimated time in operation 506.

In operation 606, the power management apparatus 100 may compare a change in power consumption of the system 103 with a predetermined predicted power consumption.

For example, the power management apparatus 100 may compare the predicted power consumption determined in step 204 of FIG. 2 with the amount of change in power consumption of the system to determine schedule information of the electronic device.

For example, after transmitting the control signal to the display device, the power management device 100 may compare the difference in power consumption of the system 103 with the predetermined predicted power consumption before and after the display device is activated.

In operation 608, the power management apparatus 100 may determine whether the comparison result is within a predetermined range. For example, the predetermined range may be an error range (eg, + 10% to -10%) with respect to the predicted power consumption. However, the present invention is not limited thereto, and the power management apparatus 100 may determine a predetermined range based on a default value stored in the power management apparatus 100 or a value set by a user.
