This model data is, for example, measurement information indicating the power consumption of the smart home appliance 131 measured in each of a plurality of homes, and is updated every 24 hours, for example.

  Note that the storage unit 23 may not be included in the power management server 102, and may be provided outside the power management server 102 as a storage device, for example.

  Here, air conditioner and lighting are included in the type information of the non-smart home appliance 132, and “multiple people live”, “home at daytime”, “many types of electrical devices” ”And“ being a saver ”are assumed to have been identified.

  In this case, the data extraction unit 26 is the air conditioner model data among the plurality of model data stored in the data storage unit 22, and is “at home in the daytime”. Model data associated with lifestyles such as “has a lot of types of electrical equipment” and “is a saver”. The data extraction unit 26 is illumination model data among a plurality of model data stored in the storage unit 23 and is “home to multiple people” or “at home during the daytime”. ", Model data associated with lifestyles of" many types of electrical equipment "and" is a saver "are extracted.

The received estimation result is stored (step S17).

  Next, when the user transmits an acquisition request for power consumption information of each non-smart 132 to the device management apparatus 101 using, for example, a terminal device (step S18), the device management apparatus 101 stores the estimation result stored therein. Specifically, the power consumption information for 24 hours of each non-smart 132 is transmitted to the terminal device (step S19).

(Power consumption estimation process)
FIG. 7 is a flowchart showing an operation procedure in the power consumption estimation process shown in FIG.

  With reference to FIG. 7, first, the power management server 102 receives the type information of the non-smart home appliance 132, the total power consumption information, and the power consumption information of each smart home appliance 131 from the device management apparatus 101 (step S21). .

  Next, the power management server 102 specifies the lifestyle of the user based on the received information.

  For example, based on the received information, the power management server 102 determines whether or not it is living with a plurality of people, whether or not it tends to be at home during the daytime, whether it is a saving home or a waste home, and installation A life style such as whether there are many types of electric devices being used is specified (step S22).

  Next, for each type of electrical device included in the type information of the non-smart home appliance 132, the power management server 102 stores model data of the same type of electrical device that is associated with the identified lifestyle. Extract (step S23).

  Next, the power management server 102 calculates, based on the total power consumption information and the power consumption information of each smart home appliance 131, for example, the total power consumption of the plurality of non-smart home appliances 132 included in the type information of the non-smart home appliance 132, The extracted model data is corrected so as to be equal to the difference between the total power consumption of the electrical device group and the power consumption of the smart home appliance 131 (step S24).

  And the power management server 102 acquires the power consumption shown by each model data after a correction process as an estimation result of the power consumption of each non-smart home appliance 132 (step S25). Then, the power management server 102 transmits the acquired estimation result to the device management apparatus 101 (step S16 illustrated in FIG. 5).

  The power management server 102 specifies, for example, an electric device that consumes more power than the model data of the same type of electric appliances among the smart appliance 131 and the non-smart appliance 132, and the specified electric appliance is set as a power saving target. It is possible to create a comment indicating that the device is an effective electrical device and notify the device management apparatus 101 together with the estimation result.

(Specific examples of correction processing)
(I) Specific example 1
FIG. 8 is a diagram for explaining a specific example 1 of the correction process shown in FIG. In FIG. 8, the horizontal axis indicates time, and the vertical axis indicates power consumption with the unit “Wh”.

  With reference to FIG. 8, first, the power management server 102 determines the total power consumption M of the electrical device group and the power consumption M1 of the smart home appliance 131 based on the total power consumption information and the power consumption information of each smart home appliance 131. Power consumption M2 (= M−M1) is calculated as the sum of the power consumption of the plurality of non-smart home appliances 132 included in the type information of the non-smart home appliances 132. It is assumed that the temporal transition of the total M2 of the power consumption of the plurality of non-smart home appliances 132 obtained in this way is as shown in FIG.

  Here, it is assumed that the type information of the non-smart home appliance 132 includes an air conditioner and lighting. In this case, the power management server 102 extracts model data associated with the same lifestyle as the user's lifestyle for each of the air conditioner and the lighting. Specifically, as shown in FIG. 8B, the power management server 102 extracts air conditioner model data indicating the temporal transition of the power consumption Ma and lighting model data indicating the temporal transition of the power consumption Mb. To do.

  Then, the power management server 102 consumes the non-smart home appliance 132 based on the total power M2 of the non-smart home appliance 132 shown in FIG. 8A and the power consumptions Ma and Mb shown in FIG. A correction process is performed to distribute the total power M2 between the power consumption of the air conditioner and the power consumption of the illumination.

In the correction process, first, the power management server 102 calculates the sum of the power consumption Ma shown in the air conditioner model data and the power consumption Mb shown in the lighting model data (Ma + Mb) and the power consumption of the non-smart home appliances 132. A difference D from the total M2 is calculated according to the following equation (1). Note that the difference D may be a negative value.
D = M2- (Ma + Mb) (1)

Next, the power management server 102 distributes the difference D calculated by Expression (1) between the air conditioner and the lighting. At this time, the power management server 102 consumes the difference D to satisfy the following formula (2), where Da is the power consumption of the air conditioner in the difference D and Db is the power consumption of the illumination in the difference D. It distributes to electric power Da and power consumption Db.
D = Da + Db
Da: Db = Ma: Mb (2)

From the expression (2), the following expressions (3) and (4) are established.
Da = D × Ma / (Ma + Mb) (3)
Db = D × Mb / (Ma + Mb) (4)

Next, the power management server 102 uses the power consumption Da and the power consumption Db to change the power consumption Ca of the air conditioner and the power consumption Cb of the lighting, as shown in FIG. It calculates according to Formula (6).
Ca = Ma + Da (5)
Cb = Mb + Db (6)

  By performing such correction processing, the power management server 102 acquires the power consumption Ca of the air conditioner and the power consumption Cb of the lighting as the estimation result of the power consumption of the air conditioner and the estimation result of the power consumption of the lighting, respectively.

(Ii) Specific example 2
FIG. 9 is a diagram for explaining a specific example 2 of the correction process illustrated in FIG. 7. In FIG. 9, the horizontal axis indicates time, and the vertical axis indicates power consumption with the unit “Wh”.

  9 (a) and 9 (b) are the same as FIGS. 8 (a) and 8 (b).

  The power management server 102 is different from the specific example 1 described above by using the total power consumption M2 of the non-smart home appliances 132 shown in FIG. 9A and the power consumptions Ma and Mb shown in FIG. 9B. The correction process for distributing the total power consumption M2 of the non-smart home appliances 132 to the air conditioner and the lighting by the method is performed.

  For example, the power management server 102 can perform the correction process in consideration of the time variation of the power consumption indicated in the model data.

  Specifically, the standard deviation of the power consumption Ma of the air conditioner shown in the model data is σa, and the standard deviation of the power consumption Mb of the illumination shown in the model data is σb. Further, the average value of the power consumption Ma of the air conditioner indicated by the model data is μa, and the average value of the power consumption Mb of the illumination indicated by the model data is μb.

In this case, the power management server 102 assumes that the standard deviation with respect to the average value μa of the power consumption Ma of the air conditioner is Sa, and the standard deviation with respect to the average value μb of the power consumption Mb of lighting is Sb. The variation Sa and the variation Sb are calculated according to the following equations (7) and (8).
Variation in power consumption of air conditioner Sa = σa / μa (7)
Variation in illumination power consumption Sb = σb / μb (8)

  When a plurality of air conditioner model data are extracted, the power management server 102 sets the average value of the air conditioner power consumption variation Sa obtained from each model data as the air conditioner power consumption variation Sa. Similarly, when a plurality of illumination model data is extracted, the power management server 102 also calculates the average value of the illumination power consumption variation Sb obtained from each model data and the illumination power consumption variation Sb. And

Next, the power management server 102 calculates the difference D between the total power consumption Ma and the total power consumption Mb (Ma + Mb) and the total power consumption M2 of the plurality of non-smart home appliances 132 by Expressions (7) and (8). Using the variations Sa and Sb calculated by the above, the air conditioner and the lighting are distributed. That is, the power management server 102 sets the difference D to the power consumption so as to satisfy the following equation (9), where Da is the power consumption of the air conditioner in the difference D and Db is the power consumption of the illumination in the difference D. Distribution is made between Da and power consumption Db.
D = Da + Db
Da: Db = Ma × Sa: Mb × Sb (9)

From the equation (9), the following equations (10) and (11) are established.
Da = (Da × Sa) / (Da × Sa + Db × Sb) × (Da + Db) (10)
Db = (Db × Sb) / (Da × Sa + Db × Sb) × (Da + Db) (11)

Next, the power management server 102 uses the power consumption Da and the power consumption Db to calculate the power consumption Ca of the air conditioner and the power consumption Cb of the lighting, as shown in FIG. Calculate according to (13).
Ca = Ma + Da (12)
Cb = Mb + Db (13)

  By performing such correction processing, the power management server 102 acquires the power consumption Ca of the air conditioner and the power consumption Cb of the lighting as the estimation result of the power consumption of the air conditioner and the estimation result of the power consumption of the lighting, respectively. Can do.

(Model data update process)
FIG. 10 is a flowchart showing an operation procedure in the update process of the model data stored in the storage unit shown in FIG.

  Referring to FIG. 10, first, the power management server 102 receives power consumption information (measurement) of each smart home appliance 131 measured, for example, every 15 minutes from the device management apparatus 101 provided in one or a plurality of homes. Information) and save the received power consumption information. The power management server 102 receives the power consumption information of each smart home appliance 131 from another device such as the device management device 101 other than the device management device 101 that is the transmission destination of the estimation result of the power consumption of the non-smart home appliance 132. (Step S31).

  Next, the power management server 102 checks whether or not a predetermined time such as 24 hours has elapsed since the previous update process (step S32). If the predetermined time has not elapsed since the previous update process (“No” in step S32), the power management server 102 receives and stores the power consumption information of each smart home appliance 131 until the predetermined time has elapsed. repeat.

  On the other hand, when the predetermined time has elapsed since the previous update process (“Yes” in step S32), the power management server 102, for example, based on the power consumption information of each smart home appliance 131 for the last 24 hours, The life style of the corresponding user is specified from the stored power consumption information. In addition, when the power management server 102 receives the power consumption information of each smart home appliance 131 from the device management apparatus 101 provided in each of a plurality of homes, the power management server 102 identifies the lifestyle of the user for each home (step S33).

  Next, the power management server 102 associates the received power consumption information of each smart home appliance 131 with the identified lifestyle, thereby determining the measured power consumption information of the smart home appliance 131, that is, model data, and the lifestyle. Create multiple combinations of. Then, the power management server 102 performs an update process in which the plurality of combinations are classified for each type of electrical equipment and are newly stored in its own storage unit 23 (step S34).

  Then, the power management server 102 repeats reception and storage of the power consumption information of each smart home appliance 131 until a predetermined time elapses again (step S31).

  Note that the power management server 102 is not limited to the configuration in which the power consumption information itself of each smart home appliance 131 is stored in its own storage unit 23, but information after performing some arithmetic processing or the like on the power consumption information of each smart home appliance 131.

Further, the estimation unit 22 uses the power consumption information of the smart home appliance 131, the total power consumption information, and the type information of each non-smart home appliance 132 acquired by the acquisition unit 21. Estimate power. In addition, the presentation unit 24 presents the power consumption of each non-smart home appliance 132 estimated by the estimation unit 22.

  As described above, by using the power consumption information of the smart home appliance 131 and the information for identifying the non-smart home appliance 132, the power consumption of each non-smart home appliance 132 that does not have the power consumption notification function is estimated. Even when the non-smart home appliance 132 is included in an electrical device provided in the house or the like, the power consumption of the non-smart home appliance 132 can be presented to the user.

  Moreover, in the power management server 102 in the power management system 201 according to the first embodiment of the present invention, the estimation unit 22 calculates the breakdown of the difference between the total power consumption of the electrical device group and the power consumption of the smart home appliance 131. The power consumption of each non-smart home appliance 132 is estimated.

  In this way, complicated calculation processing is performed by a configuration that estimates the breakdown of the difference between the total power consumption of the electrical device group and the power consumption of the smart home appliance 131, that is, the total power consumption of the plurality of non-smart home appliances 132. Therefore, the power consumption of each standard device can be estimated more accurately.

  In addition, in the power management server 102 in the power management system 201 according to the first embodiment of the present invention, the estimation unit 22 removes the non-smart home appliance 132 from the storage unit 23 that stores model data of power consumption of the electrical device. Based on the type information for identification, model data of the same type of electrical device as the non-smart home appliance 132 is acquired, and the acquired model data, the power consumption information of the smart home appliance 131, and the total power consumption information of the electrical device group Based on this, the power consumption of the non-smart home appliance 132 is estimated.

  With such a configuration, the arithmetic processing for estimating the power consumption of each non-smart home appliance 132 can be further simplified.

  Further, in the power management server 102 in the power management system 201 according to the first embodiment of the present invention, the estimation unit 22 determines that the total power consumption indicated in the acquired model data of each non-smart home appliance 132 is an electrical device. Correct the model data of each non-smart home appliance 132 acquired so as to be equal to the difference between the total power consumption of the group and the power consumption of the smart home appliance 131, that is, the total power consumption of the plurality of non-smart home appliances 132, The power consumption indicated in each model data after the correction process is estimated as the power consumption of each non-smart home appliance 132.

  With such a configuration, the power consumption indicated in the model data can be brought close to the power consumption of the non-smart home appliance 132 to be estimated, and the estimation accuracy of the power consumption of the non-smart home appliance 132 can be improved.

  Moreover, in the power management server 102 in the power management system 201 according to the first embodiment of the present invention, the estimation unit 22 takes into account the time variation of the power consumption indicated in the acquired model data of the non-smart home appliance 132. Perform correction processing.

  With such a configuration, for example, when the time variation of the power consumption indicated in the model data is different for each type of electric device, the time variation of the power consumption for each type of the electric device is reflected in the correction process of the model data. It is possible, and the estimation accuracy of the power consumption of each non-smart home appliance 132 can be further enhanced.

  In the power management server 102 in the power management system 201 according to the first embodiment of the present invention, the storage unit 23 includes the type of electrical device, the lifestyle of the user of the electrical device, and model data of the electrical device. The correspondence relationship is stored. In addition, the estimation unit 22 determines the corresponding user's power based on at least one of the power consumption information of the smart home appliance 131, the total power consumption information of the electrical device group, and the type information of the non-smart home appliance 132. A life style is specified, and model data corresponding to the specified life style is acquired from a plurality of model data stored in the storage unit.

  With such a configuration, model data indicating power consumption closer to the power consumption of the non-smart home appliance 132 that is the estimation target can be acquired from the plurality of model data, and thus the power consumption of each non-smart home appliance 132 is estimated.
