[Outline of power consumption estimation device 1]
FIG. 1 is a diagram showing an outline of a power consumption estimation device 1 according to this embodiment. The power consumption estimation device 1 is a server that estimates the power consumption of each device installed in a predetermined facility.

The power consumption estimation apparatus 1 is communicably connected to the smart meter 2 and the mobile terminal 3 via a communication network such as the Internet or a mobile phone line. The smart meter 2 is a device that measures power consumption in a predetermined facility. The mobile terminal 3 is, for example, a mobile phone such as a smartphone carried by a user who uses a predetermined facility. Here, the predetermined facility is, for example, a detached house or a space corresponding to one household in an apartment house. In the present embodiment, the description will be made assuming that the predetermined facility is a detached house and the user who uses the predetermined facility is a resident of the house. Further, in the following description, the predetermined facility is also simply referred to as a facility.

The power consumption estimation device 1 specifies the in-facility power consumption by acquiring from the smart meter 2 the information indicating the in-facility power consumption that indicates the amount of power consumed in the facility in a predetermined period ((1 in FIG. 1 )). The power consumption estimation device 1 is installed in a facility and estimates a constant power consumption amount which is a power amount consumed in a predetermined period by a first device which operates by constantly consuming power ((2) in FIG. 1). ).

The power consumption estimation device 1 estimates the operating time and the power consumption of each device installed in the facility in a predetermined period based on the power consumption in the facility and the constant power consumption (see FIG. 1). (3)). The power consumption estimation device 1 outputs information indicating the ratio of power consumption of each device to the mobile terminal 3 ((4) in FIG. 1). By doing so, the user can grasp the breakdown of each device estimated with respect to the power consumption amount actually consumed in the facility, and the user can save power.

[Configuration of Power Consumption Estimation Device 1]
Then, the structure of the power consumption estimation apparatus 1 is demonstrated. FIG. 2 is a diagram showing a configuration of the power consumption estimation device 1 according to the present embodiment. As shown in FIG. 2, the power consumption estimation device 1 includes a communication unit 11, a storage unit 12, and a control unit 13.

The communication unit 11 is a communication interface for transmitting and receiving data between the smart meter 2 and the mobile terminal 3.
The storage unit 12 is a storage medium including a ROM (Read Only Memory) and a RAM (Random Access Memory). The storage unit 12 stores a program executed by the control unit 13. For example, the storage unit 12 controls the control unit 13 to include the specifying unit 131, the first power amount estimating unit 132, the first operating time estimating unit 133, the second power amount estimating unit 134, the second operating time estimating unit 135, and the third operating time. A power consumption estimation program that functions as the power amount estimation unit 136, the third operating time estimation unit 137, the fourth power amount estimation unit 138, and the output unit 139 is stored.

The control unit 13 is, for example, a CPU (Central Processing Unit). The control unit 13 executes the power consumption estimation program stored in the storage unit 12 to specify the identification unit 131, the first power amount estimation unit 132, the first operating time estimation unit 133, the second power amount estimation unit 134, The second operation time estimation unit 135, the third power amount estimation unit 136, the third operation time estimation unit 137, the fourth power amount estimation unit 138, and the output unit 139 function.

The identifying unit 131 identifies the in-facility power consumption that indicates the amount of power consumed in a predetermined facility during a predetermined period. For example, the identifying unit 131 uses, from the smart meter 2 installed in the facility, facility identification information for identifying the facility at predetermined intervals and consumption consumed by the facility in each of a plurality of time frames obtained by dividing the predetermined period. Get the amount of electricity and. The facility identification information is, for example, the identification information of the smart meter 2 or the customer identification information set by the power company for the user. The identifying unit 131 identifies the in-facility power consumption by calculating the sum of the power consumptions in each of the acquired time frames. The identifying unit 131 associates the in-facility power consumption with information (for example, date) indicating a predetermined period and stores the information in the storage unit 12 as power consumption information.

Here, the predetermined period is a period corresponding to the life cycle of the user, and is, for example, one day. One time frame is, for example, 30 minutes. The identifying unit 131 acquires, from the smart meter 2 every other day, the amount of power consumption of the previous day consumed in the facility in each of 48 time frames obtained by dividing the day into 30 minutes. Then, the identifying unit 131 identifies the in-facility power consumption by totaling the power consumptions of the 48 time frames.

The first power amount estimation unit 132 estimates the constant power consumption amount indicating the amount of power consumed in a predetermined period by the first device installed in the facility and operating by constantly consuming power.
The first device is, for example, a refrigerator. The first power amount estimation unit 132 estimates the power consumption amount with the highest appearance ratio among the power consumption amounts corresponding to each of the plurality of time frames as the constant power consumption amount per time frame.

FIG. 3 is a diagram illustrating an example of the power consumption amount of a predetermined facility in a predetermined period. For example, in the time zone during which the user is sleeping, such as 0:00 to 6:00 and 23:00 to 24:00, shown in FIG. High power consumption is likely. Therefore, the power consumption estimation apparatus 1 can accurately estimate the constant power consumption per time frame based on the power consumption with the highest appearance rate.

It should be noted that the first power amount estimation unit 132 performs rounding processing such as rounding down or rounding up of fractional values of the power consumption amount corresponding to each of the plurality of time frames when specifying the power consumption amount having the highest appearance ratio. Good. By doing so, the power consumption estimation apparatus 1 suppresses that the power consumption with the highest appearance ratio cannot be specified because the power consumptions corresponding to the plurality of time frames are all slightly different. You can

Further, the first power amount estimation unit 132 estimated the power consumption amount with the highest appearance ratio as the constant power consumption amount per time frame, but the present invention is not limited to this. The first power amount estimation unit 132 may estimate the minimum power consumption amount among the power consumption amounts corresponding to each of the plurality of time frames as the constant power consumption amount per time frame. By doing so, the power consumption estimation apparatus 1 estimates the constant power consumption per time frame based on the power consumption with the highest appearance ratio, similarly to the constant power consumption per time frame. Can be accurately estimated.

Then, the first power amount estimation unit 132 estimates the constant power consumption amount in the predetermined period based on the constant power consumption amount per time frame. For example, when the predetermined period is one day and one time frame is 30 minutes, the first power amount estimation unit 132 is the constant power consumption amount per time frame and the number of time frames in one day. The constant power consumption in one day is estimated by multiplying by.

In addition, the first power amount estimation unit 132 may determine whether or not the facility is used by the user based on the relationship between the power consumption amount in the facility and the constant power consumption amount in a predetermined period. For example, the first power amount estimation unit 132 determines that the facility is not used by the user when the difference between the power consumption amount in the facility and the constant power consumption amount in the predetermined period is within the predetermined threshold value. Here, the predetermined threshold is, for example, 5% of the constant power consumption. When the first power amount estimation unit 132 determines that the facility is not used by the user, the first power amount estimation unit 132 estimates that the in-facility power consumption amount in the predetermined period is the constant power consumption amount in the predetermined period.

For example, when the user is not in the facility for a long trip or the like, it means that only the first device consumes power in the facility. Therefore, the power consumption estimation device 1 can accurately estimate the constant power consumption in the predetermined period based on the power consumption in the facility when the facility is not used by the user.

When estimating the constant power consumption amount, the first power amount estimation unit 132 associates the constant power consumption amount with information indicating a predetermined period (for example, date), and stores it in the storage unit 12 as power consumption amount information.

The first operating time estimation unit 133 is installed in the facility based on the in-facility power consumption identified by the identification unit 131 and the constant power consumption estimated by the first power consumption estimation unit 132. The operating time of the device in a predetermined period indicating the period corresponding to the life cycle of the user is estimated. The second device is a device used at a specific time regardless of the season, for example, a lighting device. The first operating time estimation unit 133, for example, based on the time corresponding to night, the in-facility power consumption specified by the specification unit 131, and the constant power consumption estimated by the first power consumption estimation unit 132, Estimate the operating hours of lighting equipment.

Specifically, first, the first operating time estimation unit 133 selects one time frame from the plurality of time frames in the predetermined period. The first operating time estimation unit 133 specifies whether the selected time frame is a night time frame or a daytime time frame.

For example, the control unit 13 functions as a reception unit, receives the facility identification information and the position information indicating the position of the facility from the user in advance from the mobile terminal 3 used by the user of the facility, and the facility identification information and the position. The information is associated and stored in the storage unit 12 as facility position information. The first operating time estimation unit 133 refers to the facility location information, identifies the location information associated with the facility identification information acquired by the identification unit 131 together with the power consumption amount consumed in the facility, and determines the location information. Specify the area to include. The first operating time estimation unit 133 refers to, for example, an external server that stores the sunrise and sunset times by region and day, and corresponds to the identified region and the power consumption amount acquired by the identifying unit 131. The sunrise time and sunset time corresponding to the date (previous day) to be specified are specified.

When the selected time frame is included in the time range from the sunrise time to the sunset time, the first operating time estimation unit 133 determines that the time frame is the daytime time frame, and selects the selected time frame. Is not included in the time range, it is determined that the time frame is the night time frame. In addition, at the sunrise time or the sunset time, the area around the facility is not bright, and the first operating time estimation unit 133, when the selected time frame includes the sunrise time or the sunset time, The time frame is determined to be the night time frame.

And is stored in the storage unit 12 as the first power estimation element information. The first operating time estimation unit 133 refers to the first power estimation element information, and identifies the element for estimating the power consumption of the lighting device, which is associated with the facility identification information acquired by the identification unit 131. .. Then, the first operating time estimation unit 133 estimates the power consumption amount per unit time of the lighting device installed in the facility based on the estimated elements. By doing so, the power consumption estimation device 1 can improve the estimation accuracy of the power consumption of the lighting device per unit time. For example, it is estimated that the larger the size of the facility, the number of rooms in the facility, and the number of users of the facility, the greater the amount of power consumption per unit time.

Further, the first operating time estimation unit 133 receives product identification information such as a model number for identifying a lighting device used in the facility from the mobile terminal 3 used by the user of the facility, and stores the product identification information in the storage unit 12. It may be stored in. The first operating time estimation unit 133 refers to, for example, an external server that stores the catalog information of the lighting device, specifies the catalog information corresponding to the product identification information of the lighting device stored in the storage unit, and the catalog information. On the basis of the specification information of the lighting device posted in, the power consumption of the plurality of lighting devices installed in the facility in the time frame may be specified. Then, the second operating time estimation unit 135 may estimate the power consumption amount per unit time of the lighting device installed in the facility based on the specified power consumption amounts of the plurality of lighting devices.

For example, when the unit time is 1 hour and one time frame is 30 minutes, and the power consumption of the lighting device per unit time is Plu, the power consumption of the lighting device in the time frame is Pl/2. .. Let Pss be the power consumption amount consumed in the facility corresponding to the selected time frame, Pcs be the constant power consumption amount corresponding to the time frame, and the unit time is 1 hour, and one time frame is 30 minutes.

Pss-Pcs-Plu/2≧0...(1)

When the time frame is the daytime time frame, the first operating time estimation unit 133 determines that the lighting device is not operating in the time frame. Then, the first operating time estimation unit 133 estimates the operating time of the lighting device in the predetermined period by summing the time frames determined that the lighting device was operating.

The storage of the operation determination information in the storage unit 12 is repeated.

The second power amount estimating unit 134 calculates the operating time estimated by the first operating time estimating unit 133 and the power consumption per unit time of the second device (lighting device) predetermined by the first operating time estimating unit 133. The amount of power consumption of the second device in a predetermined period is estimated based on the amount. Specifically, the second power amount estimation unit 134 estimates the power consumption amount of the lighting device in a predetermined period by multiplying the power consumption amount of the lighting device per unit time by the estimated operating time.

When estimating the power consumption amount of the lighting device, the second power amount estimation unit 134 associates the power consumption amount of the lighting device with information (for example, date) indicating a predetermined period, and stores the power consumption amount information as the storage unit 12 Memorize.
