When the current value (instantaneous current value) used exceeds the contract current value, the power supply is cut off (so-called breaker is in a broken state). When such a situation occurs, the operation of the electronic device that has been used until then is forcibly stopped, and as a result, there is a risk of causing an unintended inconvenience. Therefore, a technique for preventing the occurrence of such a situation is desired.

In the case of the technique described in Patent Document 1, inconvenience exceeding the contract current value can be suppressed by shifting the peak of power consumption by using power charged in an energy device such as a battery. However, this technology cannot be used if there are no devices such as energy devices or storage system managers. Further, when an energy device such as a battery is used for another purpose when the power consumption is large, a peak shift of the power consumption cannot be realized.

In the case of the technology described in Patent Document 2, it is necessary to construct a new breaker between the outlet and the switchboard. Such construction is troublesome.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The apparatus of this embodiment includes a CPU (Central Processing Unit) of an arbitrary computer, a memory, a program loaded in the memory (a program stored in the memory from the stage of shipping the apparatus in advance, a CD (Compact Disc) and other storage media and programs downloaded from servers on the Internet), storage units such as hard disks for storing the programs, and any combination of hardware and software, centering on the network connection interface Is done. It will be understood by those skilled in the art that there are various modifications to the implementation method and apparatus.

Further, the functional block diagram used in the description of the present embodiment shows functional unit blocks, not hardware unit configurations. In these drawings, each device is described as being realized by one device, but the means for realizing it is not limited to this. That is, it may be a physically separated configuration or a logically separated configuration.

<First Embodiment>
First, an outline of the power management apparatus of this embodiment will be described.
The power management apparatus according to the present embodiment predicts in advance the occurrence of inconvenience that the instantaneous value, which is the instantaneous power value (W) or the instantaneous current value (A), exceeds a predetermined threshold value (hereinafter referred to as a use restriction threshold value). Means to do. For this reason, when the power management apparatus predicts that the instantaneous value exceeds the use restriction threshold, the power management apparatus or the like executes some means for preventing the situation from occurring before the situation occurs. Can do.

By the way, as a means for predicting inconvenience that the instantaneous value exceeds the use limit threshold, for example, when the instantaneous value is compared with the use limit threshold, and the difference becomes smaller than a predetermined value (hereinafter, difference threshold) ( It is conceivable to determine that there is a possibility that the instantaneous value exceeds the use restriction threshold (hereinafter, the possibility of excess) when the instantaneous value approaches the use restriction threshold).

However, in the case of this means, the accuracy of prediction is not sufficient. For example, even if the difference between the instantaneous value and the use restriction threshold is smaller than the difference threshold, the instantaneous value may not exceed the use restriction threshold thereafter. Based on the difference between the instantaneous value and the usage limit threshold being smaller than the difference threshold, it is determined that the instantaneous value may exceed the usage limit threshold, and the power consumption value and current consumption value are suppressed based on the determination. When some process (such as stopping the operation of one or more electronic devices) is executed, but the actual value does not exceed the use limit threshold, the process for suppressing the power consumption value and the current consumption value is unnecessary. It becomes processing.

In the case of this means, if the difference threshold is made too small, the time from when it is determined that there is a possibility of exceeding it to the time when it actually exceeds the use limit threshold becomes extremely small, and the processing for suppressing the power consumption value and the current consumption value. Etc. may not be able to be executed. On the other hand, if the difference threshold is increased too much, it is determined that there is a possibility that the difference will be exceeded, but in reality, there is a high possibility that a situation will occur in which the instantaneous value does not exceed the use restriction threshold.

The power management apparatus according to the present embodiment predicts the occurrence of inconvenience that the instantaneous value exceeds the use limit threshold by a new means capable of suppressing such inconvenience.

Specifically, the power management apparatus acquires an instantaneous value of a predetermined monitoring target unit. The monitoring target unit includes one or more electric devices. The instantaneous value of the monitoring target unit is a total value of the power consumption value or the current consumption value of the electric equipment included in the monitoring target unit. In addition, the power management device changes the operation content from each of one or a plurality of electronic devices included in the monitoring target unit (eg, power OFF → ON, the air conditioning heating set temperature is changed from 24 ° C. to 25 ° C. Or the like) is received. When the electronic device receives an instruction input for changing the operation content from the user, the electronic device transmits the change information to the power management apparatus. When the change information is received, the power management device uses the instantaneous value and the change information, and when the operation content specified by the change information is changed, the changed instantaneous value of the monitoring target unit is used. It is determined whether or not the limit threshold is exceeded.

The predicted value (for example, the maximum predicted value) of power and current consumed by each electronic device can be predicted in advance with sufficient accuracy based on the design and the like. For this reason, when the operation content of a certain electronic device is changed, it can be predicted with sufficient accuracy how much the instantaneous value increases due to the change. As a result, when the operation content specified by the change information is changed, it can be determined with sufficient accuracy whether or not there is a problem that the instantaneous value after the change exceeds the use limit threshold.

In addition, the power management apparatus according to the present embodiment determines that the instantaneous value after the change is based on the determination result of how much the instantaneous value increases when the operation content specified by the change information is changed. Judge whether there is a possibility of exceeding. For this reason, the power management apparatus according to the present embodiment is different from the case where the difference between the instantaneous value and the use restriction threshold is determined to be “probable to exceed” based on the fact that the difference between the instantaneous value and the use restriction threshold is reduced to some extent. It can be judged that there is a possibility of exceeding at a stage where the is large. As a result, if the instantaneous value rises at the same speed after these determination points, the present embodiment can earn longer time until the use limit threshold is reached. And appropriate response processing can be performed within this time.

Next, the configuration of the power management apparatus of this embodiment will be described with reference to the drawings. FIG. 1 shows an example of a functional block diagram of the power management apparatus 10 of the present embodiment. FIG. 1 shows a distribution board 20 and an electronic device 30 in addition to the power management apparatus 10. The power management apparatus 10 can transmit / receive information to / from the distribution board 20 and the electronic device 30 by wired and / or wireless communication (indicated by a solid line in the figure). In addition, the power management apparatus 10 and the electronic device 30 are configured to receive power supply via the distribution board 20 (indicated by dotted lines in the figure). Since the configuration of the distribution board 20 can be realized in accordance with the prior art, description thereof is omitted here.

Fig. 18 shows another example. The example shown in FIG. 18 is further different from the example of FIG. 1 in that the measuring device 40 is shown. The measuring device 40 is connected to the distribution board 20 and measures an instantaneous power value and an instantaneous current value. Then, the measuring device 40 inputs the measurement result to the power management device 10. Information communication is possible between the measurement device 40 and the power management device 10 by wired and / or wireless communication. Note that all communication between the measurement device 40, the power management device 10, and the electronic device 30 may be performed wirelessly.

First, the electronic device 30 will be described. The type of electronic device 30 is not particularly limited, and includes all types of devices such as an air conditioner, a television, a refrigerator, a lighting fixture, a washing machine, a dryer, and a personal computer. The electronic device 30 can transmit / receive information to / from the power management apparatus 10 through wired and / or wireless communication. The electronic device 30 is preferably configured to be able to transmit and receive information to and from the power management apparatus 10 wirelessly via a network such as a wireless LAN or the Internet. The electronic device 30 receives power supply through the distribution board 20 and operates. There may be one electronic device 30 or a plurality of electronic devices 30.

The one or more electronic devices 30 included in the monitoring target unit are registered in the power management apparatus 10 for each monitoring target unit at a predetermined timing. By the registration, the power management apparatus 10 can specify the electronic device 30 included in each monitoring target unit, can authenticate the electronic device 30, and can transmit / receive information to / from the electronic device 30. It becomes.

The monitoring target unit includes one or a plurality of electronic devices 30. The monitoring target unit only needs to be able to specify the instantaneous value (instantaneous power value or instantaneous current value) of the unit, and what kind of unit is used is a design matter. The instantaneous value of the monitoring target unit is a total value of the power consumption value and the current consumption value of one or a plurality of electronic devices 30 included in the monitoring target unit. For example, the electronic device 30 that receives power supply through one distribution board 20 may be set as one monitoring target unit (distribution board 20 unit), or each monitoring target unit is subdivided into each monitoring target unit 20. The electronic device 30 that receives power supply by branching may be set as one monitoring target unit (a branching unit of the distribution board 20). The electronic device 30 that receives power supply through one outlet may be set as one monitoring target unit (outlet unit), or the electronic device 30 that receives power supply through one table tap may be one monitoring target unit. It is good also as (table tap unit). In addition, if a watt-hour meter (Smart Meter: Smart Meter) that measures power digitally and has a communication function in the meter is installed, the instantaneous power value or instantaneous current value is measured by the smart meter. The electronic device 30 may be a single monitoring target unit.

The means for registering the electronic device 30 is not particularly limited, but an example will be described below. For example, the user operates the power management apparatus 10 to specify one monitoring target unit (eg, distribution board unit, first outlet unit, first table tap unit, etc.) and Address information of the power management apparatus 10 is input to the electronic device 30 to be registered. Then, the electronic device 30 to be registered transmits a registration application to the power management apparatus 10 using the input address information. The power management apparatus 10 that has received the registration application determines whether to permit the application.

When permitting, the power management apparatus 10 returns a permission notification to the electronic device 30 to be registered. At this time, the power management apparatus 10 may issue identification information for identifying the newly registered electronic device 30 among the registered electronic devices 30. Then, the issued identification information and permission notification may be returned to the electronic device 30 to be registered. When permitting the application, the power management apparatus 10 registers the identification information and address information of the electronic device 30 to be newly registered in the table of the registered electronic device 30 for each monitoring target unit. The identification information may be address information, or may be identification information newly issued to the electronic device 30 to be registered as described above. Thereafter, the power management apparatus 10 authenticates the electronic device 30 using the identification information. The electronic device 30 registered in the power management apparatus 10 (hereinafter simply referred to as the electronic device 30) changes the operation content (eg, power OFF → ON, the air conditioner set temperature is changed from 24 ° C. to 25 ° C., etc.) When the input is accepted, change information indicating that the operation content is to be changed is transmitted to the power management apparatus 10.

The change information includes identification information of the electronic device 30 (identification information, address information, etc. for identifying each of the plurality of electronic devices 30 registered in the power management apparatus 10; hereinafter simply referred to as identification information. ), Information indicating the operation content after the change is included. Note that information indicating the operation content before the change may be included. For example, “Air Conditioner 1, Heating—Set Temperature 24 ° C. (Before Change), Heating—Set Temperature 25 ° C. (After Change)”, “Rice Cooker 1, Standby Mode (Before Change), Normal Rice Cooking Mode (After Change)” Or “rice cooker 1, standby mode (before change), quick cook rice mode (after change)”, “TV 1, power OFF (before change), power ON (after change)”, “TV 2, TV Broadcast reception-volume setting 18 (before change), TV broadcast reception-volume setting 22 (after change) ", etc. Although the operation details are shown here in a simplified manner, there are many settings for specifying the operation details, and if these affect the power consumption value or current consumption value, the information before the change is based on more information. In addition, the operation content of each changed electronic device 30 may be specified.

Next, the power management apparatus 10 will be described. As illustrated in FIG. 1, the power management apparatus 10 includes an acquisition unit 11, a reception unit 12, and a determination unit 13.

The acquisition unit 11 acquires an instantaneous value that is an instantaneous power value or an instantaneous current value of a monitoring target unit. That is, the acquisition unit 11 acquires the instantaneous value of the total power consumption value or the total current consumption value by one or a plurality of electronic devices 30 included in the monitoring target unit. For example, the acquisition unit 11 may be connected to the distribution board 20 as shown in FIG. In this case, the monitoring target unit can be a distribution board 20 unit, a branching unit of the distribution board 20, or the like. Or the acquisition part 11 may acquire the instantaneous value which the measuring apparatus 40 measured, as shown in FIG. In the case of the example shown in FIG. 18, the measuring device 40 is connected to the distribution board 20 and measures an instantaneous value. In addition, the measuring device 40 is installed in an outlet, a table tap, a power cord, etc. You may measure the instantaneous value of these units. Moreover, the measuring device 40 may be a watt-hour meter (Smart Meter). In this case, the monitoring target unit can be the distribution board 20 unit, the branching unit of the distribution board 20, the outlet unit, the table tap unit, or the watt-hour unit.

The receiving unit 12 receives change information indicating that the operation content in the electronic device 30 is changed from the electronic device 30 (the electronic device 30 registered in the power management apparatus 10) included in the monitoring target unit.

The determination unit 13 uses the instantaneous value of the monitoring target unit and the change information received from the electronic device 30 included in the monitoring target unit to change the operation content specified by the change information. It is determined whether or not the instantaneous value after the change exceeds a predetermined threshold (usage limit threshold). The use restriction threshold can be registered by the user, for example. The use restriction threshold may be determined based on, for example, the upper limit of the instantaneous current value determined by a contract with the power supply company, the standard value of the supplied voltage, or the like. The determination method for determining whether or not the instantaneous value exceeds the use restriction threshold is a design matter in this embodiment, but an example will be described below.

For example, the determination unit 13 may calculate an instantaneous value change value resulting from the change of the operation content based on the operation content before the change and the operation content after the change. If the sum of the calculated change value and the instantaneous value at that time does not exceed the use restriction threshold, it may be determined that the instantaneous value does not exceed the use restriction threshold. On the other hand, when the sum exceeds the use restriction threshold, it may be determined that the instantaneous value exceeds the use restriction threshold. In the present embodiment, details of the method for calculating the change value are not particularly limited. An example of a method for calculating a change value will be described in the following embodiment.

The predicted values (for example, maximum predicted values) of power and current consumed by each electronic device 30 can be predicted in advance with sufficient accuracy based on the design and the like. For this reason, when the operation content of a certain electronic device 30 is changed, it can be predicted with sufficient accuracy how much the instantaneous value increases due to the change. As a result, when the operation content specified by the change information is changed, it can be determined with sufficient accuracy whether or not there is a problem that the instantaneous value after the change exceeds the use limit threshold.

For this reason, when the determination unit 13 determines that the instantaneous value after the change exceeds the use restriction threshold, the power management apparatus 10 performs some response (for example, one or more electronic devices) to prevent the situation from occurring. Stop operation). Note that, as described above, the determination unit 13 can determine whether or not there is a problem that the changed instantaneous value exceeds the use limit threshold with sufficient accuracy. When the determination unit 13 determines that the threshold value is exceeded, there is a low possibility that the instantaneous value after the change actually does not exceed the use limit threshold value. For this reason, it is unlikely that any action taken to prevent the instantaneous value after the change from exceeding the use limit threshold is wasted.

Further, the power management apparatus 10 according to the present embodiment limits the use of the changed instantaneous value based on the determination result of how much the instantaneous value increases when the operation content specified by the change information is changed. Since it is determined whether or not the threshold value is exceeded, it can be determined that there is a possibility of exceeding the instantaneous value when the instantaneous value does not approach the use limit threshold value (the difference is sufficiently large). For this reason, it is possible to suppress the disadvantage that the time from when it is determined that there is a possibility of exceeding the time until the use limit threshold is actually exceeded becomes extremely small.

<Second Embodiment>
The power management apparatus 10 according to the present embodiment holds predicted consumption value information that identifies the predicted power consumption value or the predicted current consumption value of each electronic device 30, and uses the predicted consumption value information to change This is different from the first embodiment in that it is determined whether or not an inconvenience that the instantaneous value exceeds the use limit threshold value occurs. In addition, since the structure of the electricity distribution panel 10, the electronic device 30, and the measuring apparatus 40 is the same as that of 1st Embodiment, description here is abbreviate | omitted.

An example of a functional block diagram of the power management apparatus 10 of the present embodiment is shown in FIG. 1 or FIG. 18 as in the first embodiment. Hereinafter, the configuration of the determination unit 13 will be described. Since the configuration of the acquisition unit 11 and the reception unit 12 is the same as that of the first embodiment, description thereof is omitted here.

The determination unit 13 holds predicted consumption value information for specifying the predicted power consumption value or the predicted current consumption value of each electronic device 30 included in the monitoring target unit, and uses the predicted consumption value information to change It is determined whether or not an inconvenience occurs that the instantaneous value exceeds the use limit threshold.

2 and 3 show an example of predicted consumption value information. In these figures, predicted consumption value information indicating the predicted power consumption value is shown. The predicted consumption value information shown in FIG. 2 indicates the predicted power consumption value of each electronic device 30 when the power is turned on. The predicted consumption value information illustrated in FIG. 3 indicates the predicted power consumption value of each electronic device 30 for each operation content.

Here, an example of processing in which the determination unit 13 acquires and holds such predicted consumption value information will be described. In addition, the following is an example to the last, It is not limited to this.

The determination unit 13 determines the electronic device 30 with respect to the electronic device 30 at an arbitrary timing, for example, immediately after each electronic device 30 is registered in the power management apparatus 10 and when communication with the electronic device 30 becomes possible. Information for specifying 30 models (hereinafter referred to as model specifying information) is requested. The model specifying information may include information such as manufacturer and model number. The determination unit 13 that has acquired the model specifying information requests information indicating the predicted power consumption value or the predicted current consumption value regarding the model specifying information from a predetermined search server via a network such as the Internet. The search server holds correspondence information in which a predicted power consumption value or a predicted power consumption value is associated with each model specifying information in advance. When the search server accepts the request, the search server searches the correspondence information using the acquired model specifying information as a key, and acquires the predicted predicted power consumption value or the predicted current consumption value. Then, the acquired predicted power consumption value or predicted power consumption value is returned to the determination unit 13. The determination unit 13 associates the acquired predicted power consumption value or predicted power consumption value with the identification information of the electronic device 30 and newly stores it in the predicted consumption value information. The correspondence information can be created by the administrator of the search server based on the disclosure information or actual measurement value of each manufacturer.

Next, a process will be described in which the determination unit 13 determines whether or not there is a problem that the changed instantaneous value exceeds the use limit threshold by using the predicted consumption value information. When the determination unit 13 acquires the change information, the determination unit 13 searches the predicted consumption value information using the identification information of the electronic device 30 included in the change information and the information indicating the operation content after the change as keys, and is associated with them. The predicted predicted power consumption value or predicted current consumption value is acquired. The determination unit 13 further searches the predicted consumption value information using the identification information of the electronic device 30 included in the change information and the information indicating the operation content before the change as a key, and the predicted prediction associated with the information. A power consumption value or a predicted current consumption value may be acquired. By this process, the predicted power consumption value or predicted current consumption value before change and the predicted power consumption value or predicted current consumption value after change are acquired. By calculating these differences, the change value of the instantaneous value resulting from the change of the operation content is calculated. Note that an actual power consumption value (actual value) or current consumption value (actual value) before the change of the operation content of the electronic device 30 is grasped, and the actual power value and the predicted power consumption value or the predicted current consumption value after the change are calculated. By calculating the difference between them, the change value of the instantaneous value resulting from the change of the operation content may be calculated. Means for grasping the power consumption value (actual measurement value) or current consumption value (actual measurement value) of each electronic device 30 is not particularly limited, and a technique using teacher data (data in which a feature value and a power consumption value are associated). Any technology can be adopted.

By the way, the power consumption value and the current consumption value of the electronic device 30 in operation can vary. For this reason, as shown in FIG. 2, the predicted power consumption value or the predicted power consumption value of each electronic device 30 has a certain width. Similarly, the power consumption value and the current consumption value of an electronic device 30 may vary even when a certain electronic device 30 is operating with a predetermined operation content. For this reason, as shown in FIG. 3, the predicted power consumption value or the predicted current consumption value of each electronic device 30 that is operating with a predetermined operation content also has a certain range.

The determination unit 13 determines the maximum value of the predicted power consumption value or the predicted current consumption value after the change, and the minimum value of the predicted power consumption value or the predicted current consumption value before the change, as the change value of the instantaneous value due to the change of the operation content. A difference from the value may be calculated. Alternatively, the determination unit 13 may calculate a difference between the maximum value of the predicted power consumption value or the predicted current consumption value after the change and the intermediate value of the predicted power consumption value or the predicted current consumption value before the change. In addition, the determination unit 13 determines the actual power consumption value (actual measurement value) or current consumption value (actual measurement value) before the operation content change of the electronic device 30 and the maximum value of the predicted power consumption value or the prediction current consumption value after the change. The difference may be calculated. Thereafter, as described in the first embodiment, the determination unit 13 determines whether the changed instantaneous value exceeds the use limit threshold based on the sum of the calculated change value and the instantaneous value at that time. To do. In this way, it is possible to avoid the inconvenience of erroneously determining that the instantaneous value after the change does not exceed the use limit threshold. In particular, if the difference between the maximum predicted power consumption value or the predicted current consumption value after change and the minimum or actual value of the predicted power consumption value or current consumption value before the change is calculated and judged, It is possible to avoid the disadvantage of underestimating the value and erroneously determining that the instantaneous value does not exceed the usage limit threshold.

According to the present embodiment described above, the same effects as those of the first embodiment can be realized.

<Third Embodiment>
The power management apparatus 10 according to the present embodiment holds predicted consumption value information that identifies the predicted power consumption value or the predicted current consumption value of each electronic device 30, and uses the predicted consumption value information to change This is different from the first embodiment in that it is determined whether or not an inconvenience that the instantaneous value exceeds the use limit threshold value occurs. The configuration of the predicted consumption value information is different from that of the second embodiment. The configurations of the distribution board 10, the electronic device 30, and the measuring device 40 are the same as those in the first embodiment, and thus description thereof is omitted here.

The predicted consumption value information of the present embodiment includes, for each electronic device 30, attribute information including at least one of date, time, day of the week, weather, and temperature, and the past power consumption value or actual consumption current value. The associated information is included. Although the type of attribute information is not particularly limited, it is preferable that the attribute information is considered to have a causal relationship with the magnitude of the power consumption value or the current consumption value.

FIG. 4 shows an example of the predicted consumption value information of this embodiment. In this figure, the predicted consumption value information shown in the figure, which shows the predicted consumption value information indicating the predicted power consumption value, shows the date, day of the week, time zone, weather, temperature range, and actual value of the instantaneous value for each electronic device. Corresponds. The time zone is every hour and the temperature zone is every 5 ° C. This is a design matter. The actual value of the instantaneous value indicates the range of the instantaneous value (measured by the acquisition unit 11) measured under the condition specified by the attribute condition. In the illustrated time zone “15:00 to 16:00”, since the actual value of the instantaneous value is “0”, the electronic device 30 specified by the electronic device ID: 0001 is specified under the condition specified by the attribute condition. It can be seen that was not used.

The determination unit 13 can create such predicted consumption value information using, for example, information (instantaneous value) measured by the acquisition unit 11. Hereinafter, although an example is demonstrated, it is not limited to this. For example, when one branch of the distribution board 20 and one electronic device 30 are connected one-to-one, the power consumption value or the current consumption value of the electronic device 30 is obtained by measuring the instantaneous value of the branch. Can be calculated. The determination unit 13 holds information indicating a correspondence relationship between each branch of the distribution board 20 and each electronic device 30 and grasps a correspondence relationship between each branch and each electronic device 30 using the information. To do. Then, the instantaneous power value (or instantaneous current value) of each branch is grasped as the instantaneous power value (or instantaneous current value) consumed by each electronic device 30, and the power consumption value information is created. The attribute information acquisition unit is not particularly limited. For example, the power management apparatus 10 may include a clock unit, and may acquire information such as date, day of the week, and time from the clock unit. Moreover, the power management apparatus 10 may include a temperature measurement unit, and acquire information indicating the air temperature from the temperature measurement unit. Further, attribute information may be obtained from the providing server by making a request for the attribute information to the providing server that provides the attribute information via a network such as the Internet.

When the determination unit 13 determines whether or not a problem occurs in which the instantaneous value exceeds the use restriction threshold due to the change in the operation content of the first electronic device 30, the determination unit 13 acquires attribute information at that time. Then, the predicted consumption value information is searched using the acquired attribute information and the identification information of the first electronic device 30 as a key, and the attribute information that matches the current attribute information or the difference from the current attribute information is within a predetermined range. The result of the first electronic device 30 associated with the attribute information is acquired.

For example, the determination unit 13 may acquire a record that matches the day of the week. Alternatively, the determination unit 13 may acquire a record in which the date difference is within a predetermined date (eg, within 7 days). Or the judgment part 13 may acquire the track record in which a day of the week matches, a date difference is less than one month, and a time zone difference is less than three hours. Alternatively, the determination unit 13 may acquire a record in which the day of the week matches, the date difference is within one month, the time zone difference is within three hours, and the weather matches. Then, the determination unit 13 can set the acquired result as the predicted power consumption value or the predicted current consumption value when the power of each electronic device 30 is turned on. The processing by the determination unit 13 after specifying the predicted power consumption value or the predicted current consumption value of the electronic device 30 when the power is turned on is the same as in the first and second embodiments.

As a modification of the present embodiment, the results shown in the predicted consumption value information may be further associated with information indicating the operation content. In such a case, the determination unit 13 includes the acquired attribute information, the identification information of the first electronic device 30, and information indicating the operation content after the change included in the change information (or information indicating the operation content before the change). As a key, the predicted consumption value information is searched, and the associated operation content matches and the attribute information matches the current attribute information, or the difference from the current attribute information falls within a predetermined range. The result of the first electronic device 30 associated with certain attribute information is acquired.

For example, the determination unit 13 may acquire a record that the day of the week matches and the operation content matches. Alternatively, the determination unit 13 may acquire a record in which the date difference is within a predetermined date (eg, within 7 days) and the operation use is the same. Alternatively, the determination unit 13 may acquire a record in which the day of the week matches, the date difference is within one month, the time zone difference is within three hours, and the operation contents match. Alternatively, the determination unit 13 may acquire a record in which the day of the week matches, the date difference is within one month, the time zone difference is within three hours, the weather matches, and the operation contents match. Good. And the judgment part 13 can make the acquired performance the predicted power consumption value or the predicted current consumption value when each electronic device 30 operates with the operation content. The process by the determination unit 13 after specifying the predicted power consumption value or the predicted current consumption value of the electronic device 30 when operating with the operation content is the same as in the first and second embodiments.

In addition, the determination unit 13 of the present embodiment may further hold the predicted consumption value information described in the second embodiment. And when a track record is not acquired by the above-mentioned processing, or when a track record acquired is "0", it is 2nd implementation using the predicted consumption value information explained in the 2nd embodiment. You may perform the process demonstrated by the form. Moreover, the results of each electronic device 30 as shown in FIG. 4 do not necessarily have to be the results of all the electronic devices 30, and may be the results of some of the electronic devices 30. When the change information for changing the operation content is received from the electronic device 30 in which the record is not registered, the process described in the second embodiment is performed using the predicted consumption value information described in the second embodiment. You may go.

According to the present embodiment described above, the same operational effects as those of the first and second embodiments can be realized.

<Fourth Embodiment>
The power management apparatus 10 of the present embodiment is different from the first to third embodiments in that it includes a first output unit 14. Since the configuration of the distribution board 10 and the electronic device 30 is the same as that of the first embodiment, the description thereof is omitted here.

FIG. 5 shows an example of a functional block diagram of the power management apparatus 10 of the present embodiment. The power management apparatus 10 according to the present embodiment includes an acquisition unit 11, a reception unit 12, a determination unit 13, and a first output unit 14. Hereinafter, the configuration of the first output unit 14 will be described. In addition, since the structure of the acquisition part 11, the receiving part 12, and the judgment part 13 is the same as that of the 1st thru | or 3rd embodiment, description here is abbreviate | omitted. Note that the power management apparatus 10 of the present embodiment may be connected to the measurement apparatus 40 as shown in FIG. 18 as in the first to third embodiments.

When the determination unit 13 determines that the changed instantaneous value exceeds the use restriction threshold, the first output unit 14 outputs an alarm, transmits information indicating that to the external device, and the electronic device 30. At least one of the processes for transmitting the control information for controlling the operation is executed.

First, the process of outputting an alarm will be described. The first output unit 14 can output an alarm via any output device such as a display, a speaker, and an alarm light (light that is turned on when an alarm is output).

When the first output unit 14 outputs an alarm, the user can recognize that the instantaneous value may exceed the use limit threshold due to a change in the operation content input to the electronic device 30 immediately before that. . As a result, the user can avoid the inconvenience that the instantaneous value exceeds the use limit threshold by stopping the change of the operation content or by stopping the operation of the other electronic device 30.

Next, processing for transmitting information indicating that to an external device will be described. The user registers in advance in the power management apparatus 10 a mail address (for example, a mail address of a mobile phone) for receiving the information. When the determination unit 13 determines that the instantaneous value exceeds the use restriction threshold, the first output unit 14 may use the pre-registered mail address as the destination address and the instantaneous value may exceed the use restriction threshold. Information indicating that it is present can be transmitted. The information transmitted here may include information that can identify a change in the operation content of the predetermined electronic device 30 that causes the instantaneous value to exceed the use limit threshold. In such a case, the user can not only grasp that the instantaneous value may exceed the use restriction threshold value, but also determine which operation content in which electronic device 30 causes the instantaneous value to exceed the use restriction threshold value. Can also grasp.

When the first output unit 14 transmits information indicating the fact to the external device, the user may change the operation content input to the electronic device 30 immediately before the instantaneous value may exceed the use limit threshold. I can recognize that. As a result, the user can avoid the inconvenience that the instantaneous value exceeds the use limit threshold by stopping the change of the operation content or by stopping the operation of the other electronic device 30.

Next, processing for transmitting control information for controlling operations to the electronic device 30 will be described. The first output unit 14 can transmit control information including a change instruction for changing the operation content in a direction in which the power consumption value or the current consumption value decreases, to any one of the electronic devices 30. The electronic device 30 that is the transmission destination of the control information may be the electronic device 30 that has transmitted the change information, or may be another electronic device 30. The electronic device 30 that has received the control information changes the operation content in accordance with the change instruction. The contents of the change instruction may be, for example, a change instruction to turn off the power, a change instruction to change the set temperature of the air conditioner from 28 ° C. to 25 ° C., or the like.

The first output unit 14 holds priority information indicating the priority order of the plurality of electronic devices 30 included in the monitoring target unit, and has the lowest priority among the plurality of electronic devices 30 that are consuming power. Control information including a change instruction may be transmitted to the electronic device 30. FIG. 6 shows an example of priority order information. For example, the user operates the power management apparatus 10 to register priority order information and change the contents. In addition, the power management apparatus 10 of this embodiment can grasp | ascertain the present state of each electronic device 30 using the change information received from each electronic device 30. FIG. For this reason, it is possible to grasp whether or not each of the plurality of electronic devices 30 is operating (power is being consumed). When the priority of the electronic device 30 that has transmitted the change information is lower than the electronic device 30 having the lowest priority among the plurality of electronic devices 30 that are consuming power, the first output unit 14 The control information indicating that the change of the operation content specified by the change information is not permitted may be transmitted to the electronic device 30 that is the transmission source of the change information.

FIG. 7 is a sequence diagram illustrating an example of a processing flow of the power management apparatus 10.

The acquisition unit 11 of the power management apparatus 10 continues to acquire the instantaneous value of the monitoring target unit (S20). When the electronic device 30 included in the monitoring target unit receives an input for changing the operation content (S21), the electronic device 30 displays change information indicating the change of the operation content received in S21 as the power management apparatus 10. (S22). Then, the determination unit 13 of the power management apparatus 10 uses the instantaneous value being acquired and the change information received in S22 to change the operation content specified by the change information. It is determined whether or not the instantaneous value exceeds a predetermined use restriction threshold. Here, it is assumed that the determination unit 13 determines that the changed instantaneous value does not exceed the use restriction threshold (S23).

Then, the 1st output part 14 transmits the information (change permission notification) which shows permitting implementation of the change of the operation content specified by change information to the electronic device 30 which is the transmission source of the said change information ( S24). The electronic device 30 that has received the change permission notification then changes the operation content received in S21 (S25).

Note that during S21 to S25, the electronic device 30 is “currently processing” or “currently checking whether the usage limit threshold is exceeded due to a change in operation content” via an output device such as a display or a speaker. Information such as “Currently confirming whether the breaker will not drop due to a change in operation content” may be output.

By the way, when the change in the operation content accepted in S21 is an input for changing the main power source from OFF to ON, the electronic device 30 turns on the power source and performs the minimum function (eg: power) It may be in an energy saving mode in which only a communication function with the management device 10 and a display function for providing information to the user are activated. And if a change permission notification is received (S24), you may transfer to normal mode (mode which started the normal function) from energy-saving mode after that (S25). The assumption is the same in all the following examples.

When changing the operation content of each electronic device 30 in such a flow, it is possible to effectively avoid the inconvenience that the instantaneous value exceeds the use limit threshold.

FIG. 8 is a sequence diagram showing another example of the processing flow of the power management apparatus 10.

The acquisition unit 11 of the power management apparatus 10 continues to acquire the instantaneous value of the monitoring target unit (S10). When the electronic device 30 included in the monitoring target unit receives an input for changing the operation content (S11), the electronic device 30 displays change information indicating the change of the operation content received in S11 as the power management apparatus 10. (S12). Then, the determination unit 13 of the power management apparatus 10 uses the instantaneous value being acquired and the change information received in S12 to change the operation content specified by the change information. It is determined whether or not the instantaneous value exceeds a predetermined use restriction threshold. Here, it is assumed that the determination unit 13 determines that the changed instantaneous value exceeds the use restriction threshold (S13).

Then, the first output unit 14 transmits control information indicating that execution of the change of the operation content specified by the change information is not permitted to the electronic device 30 that is the transmission source of the change information (S14). After receiving the control information indicating that the change is not permitted, the electronic device 30 subsequently displays information indicating that the change of the operation content is not performed because the instantaneous value exceeds the use restriction threshold due to the change of the operation content. Is output via the output device (S15). Then, without changing the operation content accepted in S11 (while maintaining the previous state), the process ends (S16).

Note that during S11 to S15, the electronic device 30 is “currently processing” or “currently checking whether the usage limit threshold is exceeded due to a change in the operation content” via an output device such as a display or a speaker. Information such as “Currently confirming whether the breaker will not drop due to a change in operation content” may be output.

FIG. 9 is a sequence diagram illustrating another example of the processing flow of the power management apparatus 10.

The acquisition unit 11 of the power management apparatus 10 continues to acquire the instantaneous value of the monitoring target unit (S70). When the electronic device 30 included in the monitoring target unit receives an input for changing the operation content (S71), the electronic device 30 transmits change information indicating the change of the operation content received in S71 to the power management apparatus 10. (S72). Then, the determination unit 13 of the power management apparatus 10 uses the instantaneous value being acquired and the change information received in S72 to change the operation content specified by the change information. It is determined whether or not the instantaneous value exceeds a predetermined use restriction threshold. Here, it is assumed that the determination unit 13 determines that the changed instantaneous value exceeds the use restriction threshold (S73).

Then, the first output unit 14 outputs an alarm indicating that the instantaneous value after the change exceeds the use limit threshold (S74). The first output unit 14 continues outputting the alarm until an input indicating that the alarm has been confirmed (eg, pressing a predetermined button) is received from the user. When receiving an input indicating that the alarm has been confirmed (S75), the first output unit 14 transmits information indicating the alarm (alarm completion notification) to the electronic device 30 that is the transmission source of the change information (S76). ). The electronic device 30 that has received the alarm completion notification then changes the operation content received in S71 (S77).

Note that during S71 to S77, the electronic device 30 is “currently processing” or “currently checking whether the usage limit threshold is exceeded due to a change in operation content” via an output device such as a display or a speaker. Information such as “Currently confirming whether the breaker will not drop due to a change in operation content” may be output.

When changing the operation content of each electronic device 30 in such a flow, the instantaneous value may exceed the use restriction threshold value due to the change of the operation content before changing the operation content. Can be recognized. Then, after the user recognizes that the instantaneous value exceeds the use limit threshold, the operation content can be changed. For this reason, the time for a user to avoid the said situation can be fully earned before an instantaneous value actually exceeds a use restriction threshold value due to the change of the said operation content. Here, when the user recognizes that the instantaneous value exceeds the use limit threshold, and instructs the electronic device to change the operation content, the user may cancel the operation content change itself, The operation of the device may be controlled to reduce power consumption and current consumption. Further, when controlling other electronic devices, the control may be performed with reference to the priority order shown in FIG. 6, or the electronic control including the operation prediction within the management range based on the predicted consumption value information shown in FIG. 4. The device may be determined. Such determination may be determined by the user, or may be provided to the user by analyzing the information owned by the determination unit 13 and regarding the electronic device 30 to be controlled and the control operation. Further, the determination unit 13 may control the electronic device 30 by analyzing the information possessed and determining the electronic device 30 to be controlled and the control operation. In this case, the user is notified of information on the control and the result.

By the way, the power management apparatus 10 determines whether or not the instantaneous value exceeds the use restriction threshold by using the predicted consumption value information as shown in FIGS. In the predicted consumption value information, the predicted power consumption value or the predicted current consumption value can be defined as a power value band or a current value band having a certain width. The power management apparatus 10 uses the maximum value in the power value band or the current value band in order to avoid underestimating the change value of the power consumption or the current consumption due to the change in the operation of a certain electronic device 30. Thus, the instantaneous value after the change of the operation can be predicted. In this case, the instantaneous value may exceed the use limit threshold immediately after the operation of the electronic device 30 is changed, or may not exceed immediately after the operation limit, and may exceed at an arbitrary timing while the operation is continued. In this example, when the instantaneous value exceeds the use limit threshold instantaneously due to the change in the operation content of S77, the user can execute the process of reducing the power consumption value and the current value after S74 and before S77. The inconvenience that the instantaneous value exceeds the use limit threshold can be avoided. Further, when the instantaneous value exceeds the use limit threshold at any timing (except immediately after) after the change of the operation content in S77, the user reduces the power consumption value and the current value before reaching the timing. Can avoid the inconvenience that the instantaneous value exceeds the use limit threshold.

As a modification of the processing example, S75 to S77 are not performed, and S14 (transmission of control information indicating that no change is permitted) shown in FIG. 8 may be performed immediately before or after S74. Then, S15 and S16 shown in FIG. 8 may be performed after S14.

FIG. 10 is a sequence diagram illustrating another example of the processing flow of the power management apparatus 10.

The acquisition unit 11 of the power management apparatus 10 continues to acquire the instantaneous value of the monitoring target unit (S50). When the electronic device 30 included in the monitoring target unit receives an input for changing the operation content (S51), the electronic device 30 displays change information indicating the change of the operation content received in S51 as the power management apparatus 10. (S52). Then, the determination unit 13 of the power management apparatus 10 uses the instantaneous value being acquired and the change information received in S52 to change the operation content specified by the change information. It is determined whether or not the instantaneous value exceeds a predetermined use restriction threshold. Here, it is assumed that the determination unit 13 determines that the changed instantaneous value exceeds the use restriction threshold (S53).

Then, the 1st output part 14 transmits the information which shows that an instantaneous value may exceed a use restriction threshold to a user terminal by using the mail address registered beforehand as an address of a transmission destination (S54). When receiving the information in S54, the user terminal returns information indicating that it has been received to the power management apparatus 10 (S55).

The first output unit 14 of the power management apparatus 10 that has received the information indicating that it has been received in S55 transmits information indicating that (warning completion notification) to the electronic device 30 that is the transmission source of the change information (S56). . The electronic device 30 that has received the warning completion notification then changes the operation content received in S51 (S57).

It should be noted that during S51 to S57, the electronic device 30 is “currently processing” or “currently checking whether the usage limit threshold is exceeded due to a change in operation content” via an output device such as a display or a speaker. Information such as “Currently confirming whether the breaker will not drop due to a change in operation content” may be output.

When changing the operation content of each electronic device 30 in such a flow, the instantaneous value may exceed the use restriction threshold value due to the change of the operation content before changing the operation content. Can be notified. Then, after notifying the user that the instantaneous value may exceed the use limit threshold, the operation content can be changed. For this reason, the time for a user to avoid the said situation can be fully earned before an instantaneous value actually exceeds a use restriction threshold value due to the change of the said operation content. Here, when the user recognizes that the instantaneous value exceeds the use limit threshold, and instructs the electronic device to change the operation content, the user may cancel the operation content change itself, The operation of the device may be controlled to reduce the power consumption value or the current consumption value. Further, when controlling other electronic devices, the control may be performed with reference to the priority order shown in FIG. 6, or the electronic control including the operation prediction within the management range based on the predicted consumption value information shown in FIG. 4. The device may be determined. Such determination may be determined by the user, or may be provided to the user by analyzing the information owned by the determination unit 13 and regarding the electronic device 30 to be controlled and the control operation. Further, the determination unit 13 may control the electronic device 30 by analyzing the owned information, determining the electronic device 30 to be controlled and the control operation. In this case, the user is notified of information on the control and the result.

By the way, the power management apparatus 10 determines whether or not the instantaneous value exceeds the use restriction threshold by using the predicted consumption value information as shown in FIGS. In the predicted consumption value information, the predicted power consumption value or the predicted current consumption value can be defined as a power value band or a current value band having a certain width. And in order to avoid underestimating the change value of the power consumption or the current consumption due to the change of the operation of a certain electronic device 30, the power management apparatus 10 sets the maximum value in the power value band or the current consumption value band. It is possible to predict the instantaneous value after changing the operation. In this case, the instantaneous value may exceed the use limit threshold immediately after the operation of the electronic device 30 is changed, or may not exceed immediately after the operation limit, and may exceed at an arbitrary timing while the operation is continued. In this example, when the instantaneous value exceeds the usage limit threshold instantaneously due to the change of the operation content in S57, the user can execute a process of reducing the power consumption value and the current value after S54 and before S57. The inconvenience that the instantaneous value exceeds the use limit threshold can be avoided. Further, when the instantaneous value exceeds the use limit threshold at any timing (except immediately after) after the change of the operation content in S57, the user reduces the power consumption value and the current value before reaching the timing. Can avoid the inconvenience that the instantaneous value exceeds the use limit threshold.

As a modification of the processing example, S55 to S57 may not be performed, and S14 (transmission of control information indicating that change is not permitted) shown in FIG. 8 may be performed immediately before or after S54. Then, S15 and S16 shown in FIG. 8 may be performed after S14.

FIG. 11 is a sequence diagram showing another example of the processing flow of the power management apparatus 10.

The acquisition unit 11 of the power management apparatus 10 continues to acquire the instantaneous value of the monitoring target unit (S60). When the electronic device 30 included in the monitoring target unit receives an input for changing the operation content (S61), the electronic device 30 displays change information indicating the change of the operation content received in S61 as the power management apparatus 10. (S62). Then, the determination unit 13 of the power management apparatus 10 uses the instantaneous value being acquired and the change information received in S62 to change the operation content specified by the change information. It is determined whether or not the instantaneous value exceeds a predetermined use restriction threshold. Here, it is assumed that the determination unit 13 determines that the changed instantaneous value exceeds the use limit threshold (S63).

Then, the first output unit 14 transmits information indicating that the instantaneous value may exceed the use limit threshold to the user terminal using a pre-registered mail address as the transmission destination address (S64). Thereafter, when the user terminal receives an instruction input (for example, an email opening instruction input) for browsing the information from the user (S65), information indicating that the user has browsed the information received in S64 (information browsing processing is performed). (Information indicating that it has been executed) is returned to the power management apparatus 10 (S66).

The first output unit 14 of the power management apparatus 10 that has received the information indicating that the information browsing process has been performed in S65 transmits the information indicating the information (browsing completion notification) to the electronic device 30 that is the transmission source of the change information. (S67). The electronic device 30 that has received the browsing completion notification then changes the operation content received in S61 (S68).

Note that during S61 to S68, the electronic device 30 is “currently processing” or “currently checking whether the usage limit threshold is exceeded due to a change in the operation content” via an output device such as a display or a speaker. Information such as “Currently confirming whether the breaker will not drop due to a change in operation content” may be output.

When changing the operation content of each electronic device 30 in such a flow, the instantaneous value may exceed the use restriction threshold value due to the change of the operation content before changing the operation content. Can be recognized. Then, after making the user recognize that the instantaneous value may exceed the use limit threshold, the operation content can be changed. For this reason, the time for a user to avoid the said situation can be fully earned before an instantaneous value actually exceeds a use restriction threshold value due to the change of the said operation content. Here, after recognizing that the instantaneous value may exceed the use limit threshold, the user may cancel the operation content change when instructing the electronic device to change the operation content. The operation of other electronic devices may be controlled to reduce power consumption and current consumption. Further, when controlling other electronic devices, the control may be performed with reference to the priority order shown in FIG. 6, or the electronic control including the operation prediction within the management range based on the predicted consumption value information shown in FIG. 4. The device may be determined. Such a determination may be determined by the user, or may be analyzed from information owned by the determination unit 13 and information regarding the electronic device 30 to be controlled and the control operation may be provided to the user. Further, the determination unit 13 may control the electronic device 30 by analyzing the information possessed and determining the electronic device 30 to be controlled and the control operation. In this case, the user is notified of information on the control and the result.

By the way, the power management apparatus 10 determines whether or not the instantaneous value exceeds the use restriction threshold by using the predicted consumption value information as shown in FIGS. In the predicted consumption value information, the predicted power consumption value or the predicted current consumption value can be defined as a power value band or a current value band having a certain width. The power management apparatus 10 uses the maximum value in the power value band or the current value band in order to avoid underestimating the change value of the power consumption or the current consumption due to the change in the operation of a certain electronic device 30. Thus, the instantaneous value after the change of the operation can be predicted. In this case, the instantaneous value may exceed the use limit threshold immediately after the operation of the electronic device 30 is changed, or may not exceed immediately after the operation limit, and may exceed at an arbitrary timing while the operation is continued. In this example, when the instantaneous value exceeds the use limit threshold instantaneously due to the change of the operation content in S68, the user can execute the process of reducing the power consumption value and the current value after S65 and before S68. The inconvenience that the instantaneous value exceeds the use limit threshold can be avoided. Further, when the instantaneous value exceeds the use limit threshold at any timing (except immediately after) after the change of the operation content in S68, the user reduces the power consumption value and the current value before reaching the timing. Can avoid the inconvenience that the instantaneous value exceeds the use limit threshold.

FIG. 12 is a sequence diagram illustrating another example of the processing flow of the power management apparatus 10.

The acquisition unit 11 of the power management apparatus 10 continues to acquire the instantaneous value of the monitoring target unit (S30). When the first electronic device 30 included in the monitoring target unit receives an input for changing the operation content (S31), the first electronic device 30 uses the change information indicating the change of the operation content received in S31 as power. It transmits to the management apparatus 10 (S32). Then, the determination unit 13 of the power management apparatus 10 uses the instantaneous value being acquired and the change information received in S32 to change the operation content specified by the change information. It is determined whether or not the instantaneous value exceeds a predetermined use restriction threshold. Here, it is assumed that the determination unit 13 determines that the changed instantaneous value exceeds the use restriction threshold (S33).

Then, the first output unit 14 uses the priority order information as shown in FIG. 6 and has the lowest priority among the plurality of electronic devices 30 included in the monitoring target unit and consuming the power. The electronic device 30 (second electronic device 30) is specified. Then, the identified second electronic device 30 is determined as a target for transmitting control information including a change instruction (S34). Thereafter, the power management apparatus 10 transmits control information including a change instruction to change the operation content in a direction in which the power consumption value and the current consumption value are reduced (S35). Here, the reduction amount of the power consumption value or the current consumption value of the second electronic device 30 due to the change specified by the change instruction transmitted in S35 is A, and the first electronic device due to the change specified by the change information received in S32 When the increase amount of the power consumption value or the current consumption value of 30 is B, and the instantaneous value at the present time is C, the power management apparatus 10 makes sure that the value of (B + C−A) does not exceed the use limit threshold value The contents of the change instruction to be transmitted to the device 30 can be determined. Note that the power management apparatus 10 may specify a plurality of electronic devices 30 as the second electronic device 30 from the lower priority in S34. In this case, the reduction amount A is the sum of the reduction amounts of the power consumption value or the current consumption value of each of the plurality of second electronic devices 30. The decrease amount A and increase amount B can be calculated using predicted consumption value information as shown in FIGS. When the second electronic device 30 changes the operation content in accordance with the change instruction received in S35 (S36), the second electronic device 30 returns information indicating the change (change completion notification) to the power management apparatus 10 (S37).

The first output unit 14 of the power management apparatus 10 that has received the change completion notification in S37 then transmits to the first electronic device 30 a change permission notification that permits the change of the operation content specified by the change information received in S31. (S38). The first electronic device 30 that has received the change permission notification then changes the operation content received in S31 (S39).

It should be noted that during S31 to S39, the electronic device 30 is “currently processing” or “currently checking whether the usage restriction threshold is exceeded due to a change in the operation content” via an output device such as a display or a speaker. Information such as “Currently confirming whether the breaker will not drop due to a change in operation content” may be output.

FIG. 13 is a sequence diagram illustrating another example of the processing flow of the power management apparatus 10.

The acquisition unit 11 of the power management apparatus 10 continues to acquire the instantaneous value of the monitoring target unit (S40). When the electronic device 30 included in the monitoring target unit receives an input for changing the operation content (S41), the electronic device 30 changes the operation content (S42). In addition, the electronic device 30 transmits to the power management apparatus 10 change information for inquiring whether or not to change the operation content received in S41 (S43). Then, the determination unit 13 of the power management apparatus 10 uses the instantaneous value being acquired and the change information received in S43 to change the operation content specified by the change information. It is determined whether or not the instantaneous value exceeds a predetermined use restriction threshold. Here, it is assumed that the determination unit 13 determines that the changed instantaneous value exceeds the use restriction threshold (S44).

Then, the first output unit 14 transmits information indicating that the instantaneous value may exceed the use limit threshold to the user terminal by using a pre-registered mail address as a transmission destination address (S45).

When changing the operation content of each electronic device 30 in such a flow, it is possible to quickly notify the user that the instantaneous value may exceed the use limit threshold due to the change of the operation content. For this reason, the user may take some measures (for example, an input to stop changing the operation content input in S41, an operation to stop the operation of the other electronic device 30 in operation, etc.) to avoid the situation. it can. Note that the first output unit 14 may output an alarm instead of transmitting information indicating that the instantaneous value exceeds the use limit threshold in S45 to the user terminal.

By the way, the power management apparatus 10 determines whether or not the instantaneous value exceeds the use restriction threshold by using the predicted consumption value information as shown in FIGS. In the predicted consumption value information, the predicted power consumption value or the predicted current consumption value can be defined as a power value band or a current value band having a certain width. The power management apparatus 10 uses the maximum value in the power value band or the current value band in order to avoid underestimating the change value of the power consumption or the current consumption due to the change in the operation of a certain electronic device 30. Thus, the instantaneous value after the change of the operation can be predicted. In this case, the instantaneous value may exceed the use limit threshold immediately after the operation of the electronic device 30 is changed, or may not exceed immediately after the operation limit, and may exceed at an arbitrary timing while the operation is continued. In this example, when the instantaneous value exceeds the use restriction threshold instantaneously due to the change of the operation content in S42, the inconvenience that the instantaneous value exceeds the use restriction threshold cannot be avoided. However, if the instantaneous value exceeds the use limit threshold at any timing (except immediately after) after the change of the operation content of S42, the notification of S45 is made before the timing is reached, and the user uses the power consumption value or If the process of reducing the current value can be executed, the inconvenience that the instantaneous value exceeds the use limit threshold can be avoided.

Hereinafter, configurations of the second output unit 15, the totaling unit 16, and the third output unit 17 will be described. The configurations of the acquisition unit 11, the reception unit 12, the determination unit 13, and the first output unit 14 are the same as those in the first to fourth embodiments, and thus description thereof is omitted here. Note that the power management apparatus 10 of the present embodiment may be connected to the measurement apparatus 40 as shown in FIG. 18 as in the first to third embodiments.

The second output unit 15 outputs information indicating an instantaneous value via any output device such as a display and a speaker. This process can be realized by using the acquisition information obtained by the acquisition unit 11. FIG. 15 shows an example in which information indicating the instantaneous power value is output to the display 100. By outputting such information, the user can recognize the current power consumption value and current consumption value. Moreover, you may display the electricity bill in the predetermined time estimated from the present power consumption value. In this case, for example, based on a general electricity rate table, the electricity rate per unit time at the present time may be displayed, or an electricity rate calculated based on contract conditions for each user may be used. As a result, effects such as power saving are expected.

The aggregation unit 16 accumulates instantaneous values and performs aggregation processing. This process can be realized by using the acquisition information obtained by the acquisition unit 11. The content of the tabulation process is a design matter. For example, the instantaneous value may be grouped for each predetermined time period, and the maximum instantaneous value may be specified for each group, or every day. Processing for grouping instantaneous values and specifying the maximum instantaneous value for each group may be performed.

3rd output part 17 outputs the total result by total part 16 via all output devices, such as a display and a speaker. FIG. 16 shows an example of outputting the total result on the display 100. In this example, the maximum instantaneous power value (maximum instantaneous value) on January 1, 2013 is shown, and the maximum instantaneous power value (hourly maximum instantaneous value) for each hour is shown. By outputting such information, the user can be made aware of what conditions (date, time zone, etc.) the power consumption is high. As a result, effects such as power saving are expected.

Note that part or all of the information acquired by the power management apparatus 10 (information described in the first to fifth embodiments) is transmitted to the HEMS server via the BBR and the Internet. The HEMS server manages the received information. For example, the user may be able to access the HEMS server using a mobile terminal and browse information managed by the HEMS server. By transmitting information from the power management apparatus 10 to the HEMS server in a shorter span (for example, real-time processing), other users who are not at home or at the office or the like can check the power usage status while away from home. Can do.

In addition, the HEMS server may analyze the past power consumption performance and perform peak prediction of power consumption from the trend. The peak prediction may be performed using the attribute information described in the third embodiment. For example, the HEMS server may analyze the state in which the power consumption increases when the condition such as the day of the week, the time zone, the weather, or the temperature zone is present. Then, peak prediction of power consumption may be performed based on the analysis result and the current condition (or future prediction condition). And a HEMS server may transmit a prediction result to a user terminal. In such a case, the user can take measures to reduce the power consumption based on the peak prediction of the power consumption sent from the HEMS server.
