In such a case, unless the wording of a device capable of selecting a plurality of air conditioners is used, that is, unless the plurality of air conditioners are selected as different devices, accurate association with the branch circuit cannot be performed. When a plurality of devices made of the same home appliance are connected to the same distribution board, devices different from each other can be sorted by, for example, a model number.

(First Embodiment)
FIG. 1 is a schematic configuration diagram illustrating an outline of a user registration support system (hereinafter, simply referred to as a support system) 1 that executes the display method according to the first embodiment of the present disclosure. In the following, first, the flow of power consumption (power consumption) data of the device will be described with reference to FIG. 1.

Two voltage lines (not shown) made of high-voltage and low-voltage electric wires are electrically connected to the distribution board 10 from, for example, a transformer of a utility pole via a power meter (not shown). The distribution board 10 includes one main switch (leakage breaker), a plurality of branch switches, and a plurality of branch circuits. The above two voltage lines are electrically connected to each branch switch via the main switch. Each branch switch is electrically connected to a corresponding branch circuit. Each branch circuit includes wiring from the corresponding branch switch to one or more outlets. Each branch switch has an overcurrent circuit breaker, which blocks the application of voltage to the branch circuit when an overcurrent flows through the corresponding branch circuit, and protects the wiring to the end of the branch circuit.

One or more devices are electrically connected to each branch circuit via an outlet included in the branch circuit. A power measuring instrument (not shown) is installed in each branch circuit. The power measuring instrument measures the power consumption and the amount of power consumed by one or more devices connected to the branch circuit, and a signal containing the information on the power consumption and the amount of power consumption is transmitted from each power measuring instrument via a wire or wirelessly. Is output to the home adapter 20. The home adapter 20 outputs a signal including power consumption and power consumption information to the center server 22 via the Internet 21, and the power consumption and power consumption information is stored in the storage unit 23 of the center server 22. To.

The information terminal 30 is composed of, for example, a mobile personal computer, a mobile phone, a control viewer, or the like. The information terminal 30 includes a display unit 31 composed of a touch panel or the like, and the display unit 31 displays information and also serves as an operation unit. The information terminal 30 exchanges bidirectional signals with the center server 22 using at least one of wireless and wired. A dedicated application (software) for associating a branch circuit with a device is stored in the storage unit of the information terminal 30.

Next, a method of registering the device in the selected branch circuit will be described with reference to FIGS. 2 to 4. FIG. 2 is a flowchart showing an example of a procedure for associating a device with a branch circuit, and FIG. 3 is a diagram showing an example of a target selection screen that appears on the display unit 31 when the above procedure is performed. Further, FIG. 4 is a diagram showing an example of a candidate presentation screen that appears on the display unit 31 when the above procedure is performed.

With reference to FIG. 2, when the application for associating the branch circuit with the device is started by using the operation unit of the information terminal 30, the procedure is started. For example, the display unit 31 shows the branch circuits 1 to N shown in FIG. A target selection screen for selecting one of these appears (step S1). The target selection screen has, for example, a plurality of operation units corresponding to the number of branch circuits, and the user can select a desired branch circuit by touching the operation unit corresponding to the branch circuit desired to be selected. It is preferable to add a subtitle to each branch circuit. The subtitle corresponds, for example, to the wording of the label affixed to the distribution board by the contractor to roughly indicate the area where the outlet corresponding to each branch circuit exists at the time of construction. The subtitle guides the user in selecting a branch circuit. It is not necessary to write the subtitle together on the target selection screen.

When the user selects a specific branch circuit, the center server 22 acquires the power data of the branch circuit from the storage unit 23 (step S2), and subsequently, the control unit of the center server 22 obtains the power data and the power data. The device connected to the branch circuit is extracted by using the device estimation software stored in advance in the storage unit 23 (step S3).

The extraction of the device is executed based on, for example, the amount of power consumption, the waveform of the power consumption related to the time, and the like. More specifically, the range of power consumption can be specified for each device. In addition, the power consumption waveform also shows the characteristics peculiar to the device. For example, when the device is a rice cooker, the amount of electric power consumed from the start to the end of rice cooking falls within a certain range even when individual differences are taken into consideration. Further, the rice cooking time is about 1 hour, and the power consumption becomes the largest near the middle of the rice cooking period. The storage unit 23 of the center server 22 stores the data in advance as rice cooker data. When the measured power data is similar to the power data of the rice cooker, the center server 22 extracts the rice cooker as a device connected to the branch circuit.

More mathematically, for example, the center server 22 has one or more parameters from the measured power data, namely, the magnitude of power consumption, the duration of power consumption, the time average of power consumption, and the highest in operating period. Calculate at least one of power consumption, distribution in the power consumption waveform, and time-series changes in power consumption. Then, at least one of them and the corresponding data of each device stored in advance in the storage unit 23 are subtracted to calculate the degree of separation for each device. The parameter used for estimation may be one, but it is more preferable to use two, and further preferably to use three or more.

The degree of hanare is represented by the number of levels at which the calculated value of the subtraction increases each time the hanare is deviated from a predetermined value. The above predetermined value is set for each parameter. The estimation is performed based on the average of the number of levels calculated for each parameter in each device, and one or more devices whose average value of the number of levels is equal to or less than a predetermined value are extracted.

It is assumed that devices that are always in operation, such as a refrigerator and an alarm, are registered in the selected branch circuit. At this time, the center server 22 specifies, for example, the data (power consumption, power consumption) of the device from the past accumulated data and the typical power data of the registered device, and the power data of the selected branch circuit. The data may be calculated by subtracting the power data of the device from. Then, based on the calculated data, an unregistered device connected to the branch circuit and not registered may be estimated. The center server 22 can extract one or more unregistered devices for each power waveform. It should be noted that different devices may be operating at different times at different times, in which case the power waveform has two or more power waveform portions that appear at time intervals. In this case, the unregistered device may be extracted for each power waveform portion.

Further, the device may be extracted by determining whether or not the calculated data based on the measurement data matches the condition of the corresponding data in each device stored in advance in the storage unit 23. For example, if there is a condition that the power distribution of a certain device for a certain period of time is within a certain threshold value, whether or not to extract the device by determining whether or not the calculated data satisfies the condition. May be determined.

The center server 22 outputs a signal including the information representing the extracted unregistered device and the information of the power data measured by the selected branch circuit to the information terminal 30. The control unit of the information terminal 30 receives a signal from the center server 22 and causes the display unit 31 to display a candidate presentation screen for presenting one or more device candidates presumed to be connected to the selected branch circuit (the display unit 31). Step S4). Further, the control unit of the information terminal 30 may display the power data measured by the selected branch circuit on the display unit 31 in addition to one or more device candidates on the candidate presentation screen.

FIG. 4 is a diagram showing an example of a candidate presentation screen. In the example shown in FIG. 4, the branch circuit 1 is selected, and the rice cooker is extracted as an unregistered device connected to the branch circuit 1. Then, on the candidate presentation screen, along with the illustration of the rice cooker, the magnitude of the power consumption consumed by the selected branch circuit is displayed in association with the time. Further, on the candidate presentation screen, an operation unit as to whether or not to register the rice cooker in the branch circuit 1 is displayed (step S5 in FIG. 2). The operation unit for registering or not registering the rice cooker constitutes an execution selection image for selecting whether or not to execute the association between the branch circuit and the device. The user can determine whether or not the extraction is correct by checking the consistency between the power waveform and the time when the rice cooker is operated, for example. Then, if it is determined that the extraction is correct, the rice cooker can be registered as the connection device of the branch circuit 1, and if it is determined that the extraction is incorrect, non-registration can be selected. When this registration or non-registration procedure is completed, the device registration procedure is completed.

Further, the display method includes a step of displaying a target selection screen for selecting one of one or more branch circuits provided in the facility on the display unit 31. Further, the display method is one or more candidates consisting of one or more devices estimated to be connected to the selected branch circuit based on the information regarding at least one of the power consumption and the electric energy consumption in the facility.

Therefore, the user can associate the branch circuit with the candidate device based on the candidate device.

Further, on the candidate presentation screen, information regarding at least one of the power consumption and the power consumption of one or more candidates may be displayed.

As described with reference to FIG. 4, when only one device connected to the branch circuit is operating at a specific time, the power consumption information of the branch circuit at the specific time is the only operation. Matches the power consumption information of the device. Alternatively, one or more devices may be equipped with a measuring instrument that measures at least one of the power consumption and the electric energy consumption of the device. In such a case, the information terminal can display information on at least one of power consumption and power consumption in each of the devices of one or more.

The user can easily obtain information such as the power consumption of the candidate device from the device guide, the Internet, or the like. Therefore, according to this configuration, the user can more accurately associate the branch circuit with the device.

In addition, other information includes, for example, the rated power of the candidate device and the branch name given to each branch circuit, such as "kitchen", "washing machine", and "Western room 1".

The user often recognizes the operating time of the candidate device and the operating time of the candidate device, as is clear when considering the case where the candidate device is a rice cooker. Alternatively, if the power consumption is high during the midnight hours, it can be inferred that the water heater is a candidate device. In addition, the user often recognizes the place where the candidate device exists, such as a kitchen or a Western-style room, and if the branch circuit has a label such as "kitchen", a range or a dishwasher is a candidate. Become.

According to this configuration, since the information relating the branch circuit and the device is displayed, the user can more accurately associate the branch circuit with the device.

Further, the center server 22 includes a second input unit for inputting selection circuit information regarding a branch circuit selected from one or more branch circuits provided in the facility. Further, the center server 22 is a control unit (specification) that identifies one or more candidates consisting of one or more devices presumed to be connected to the selected branch circuit based on the power information and the selected circuit information. A unit) and an output unit that outputs a signal including the information of the above-mentioned one or more candidates.

Therefore, the information terminal 30 can acquire information on one or more candidates consisting of one or more devices presumed to be connected to the selected branch circuit from the center server 22, and the information terminal 30 can acquire the one or more candidates from the display unit 31. Can be displayed on.

Further, the center server 22 may output a signal including information regarding at least one of the power consumption and the power consumption of the one or more candidates.

Further, the center server 22 may output information relating the branch circuit to the device. The information may include, for example, the above-mentioned operating time of the candidate device, the operating time of the candidate device, and the like.

According to the above configuration, the information terminal 30 can display the association information, and the user can execute a more accurate association procedure.

In the first embodiment, the case where only one device candidate exists has been described, but a plurality of device candidates may exist. In this case, for example, an illustration of the device described with reference to FIG. 4 and a graph relating the time and power consumption may be displayed for each candidate device. Then, on the candidate presentation screen, an operation unit that can select one or more candidates from a plurality of candidates may be displayed.

This operation unit can be easily realized, for example, by displaying an image similar to the image shown by reference number 41 in FIG. 4 for each device in all candidate devices. According to this configuration, two or more devices can be registered, and efficient registration becomes possible.

Further, in the first embodiment, the information terminal does not display the advice on the display unit when associating the selected branch circuit with the device, but the information terminal is the selected branch circuit and the device. When associating with, advice may be displayed on the display unit. For example, suppose that when a user selects a branch circuit, the dishwasher is already registered in the branch circuit and the microwave oven is listed as a candidate device. At this time, the display unit of the information terminal may display a wording meaning that the breaker is likely to be tripped if the microwave oven and the dishwasher are connected to the same circuit. More precisely, when the sum of the maximum power consumption of each device connected to the branch circuit is equal to or greater than the predetermined power (power at which the breaker is tripped), a wording indicating that the breaker is likely to be tripped is displayed. May be good.

Further, in the first embodiment, the information output system is the center server 22, but the information output system may be HEMS. More specifically, for example, the HEMS may receive the power information of each branch circuit from the distribution board by wire or wirelessly, and the information terminal may receive the candidate device information directly from the HEMS or via the Internet.

(Second Embodiment)
FIG. 5 is a diagram showing an example of a candidate presentation screen in the display method of the second embodiment. In all of the following embodiments and modifications including the second embodiment, the same configurations as those of the first embodiment are designated by the same numbers as those of the first embodiment, and the description thereof will be omitted. Further, in all the following embodiments and modifications including the second embodiment, the same effects and modifications as those of the first embodiment will not be described.

In the second embodiment, unlike the first embodiment, the devices already registered and their information are also presented on the candidate presentation screen. That is, as in the example shown in FIG. 5, the candidate presentation screen associates the magnitude of the power consumption consumed by the branch circuit 2 with the time together with the illustration of the air conditioner already registered for the selected branch circuit 2.

Further, in addition to the display of the registered device and the operation unit for deleting the registration of the registered device, the power consumption consumed by the corresponding branch circuit may be displayed.

(Third Embodiment)
In the first and second embodiments, connection device candidates are presented for the branch circuit selected by the user. However, in the third embodiment, the user selects a device, and the connection branch circuit candidate is presented to the selected device. The display method of the third embodiment can also be applied to the user registration support system shown in FIG. FIG. 6 is a diagram showing an example of a flowchart corresponding to FIG. 2 in the display method of the third embodiment.

When the application for associating the device with the branch circuit is started with reference to FIG. 6, the procedure starts, and for example, the target selection screen for selecting the device appears on the display unit 31 of the information terminal 30 (step S11). The target selection screen may include, for example, an image displaying the names of all devices connected to the distribution board via an outlet, and the user selects a device by touching the display location of the device to be selected. But it may be. When a plurality of devices include a plurality of the same home appliances, it is preferable to distinguish the plurality of the same home appliances by a model number. The target selection screen may include a device input unit (for example, composed of a rectangular blank) in which a user can input a device to be selected, and the user selects a device by inputting a desired device in the input unit. It may be configured to be used.

When the user selects a specific device, the center server 22 extracts the device associated with the device name (step S12). Then, a candidate for a branch circuit to which the extracted device is connected is estimated and extracted (step S13). More specifically, the center server 22 is based on the power consumption of each branch circuit from the distribution board 10 and includes one or more branch circuits including a power consumption portion similar to at least a part of the general power waveform of the selected device. Select. For example, when the difference in the amount of power consumption in the same time interval between the actual measurement and the general power consumption waveform is equal to or less than a predetermined value, it may be determined that the similar power consumption portion exists.

The center server 22 outputs a signal including information representing the extracted branch circuit and information of power data measured by the extracted branch circuit to the information terminal 30. The control unit of the information terminal 30 receives a signal from the center server 22 and causes the display unit 31 to display a candidate presentation screen showing a selected branch circuit and a graph relating the time and power consumption in the branch circuit. (Step S14).

FIG. 7 is a diagram showing an example of a candidate presentation screen. In the example shown in FIG. 7, an illustration of the selected rice cooker is displayed, the branch circuit A is presented as a candidate to which the rice cooker is connected, and the magnitude of the power consumption in the branch circuit A is also displayed in association with the time. ..

Further, on the candidate presentation screen, an operation unit as to whether or not to register the rice cooker in the branch circuit A is displayed (step S5 in FIG. 6). The operation unit for registering or not registering the rice cooker constitutes an execution selection image for selecting whether or not to execute the association between the branch circuit and the device. The user can select registration or non-registration of the rice cooker in the branch circuit A in this execution selection image. When the selection of registration or non-registration is completed, the circuit registration procedure is completed.

It is assumed that devices that are always in operation, such as a refrigerator and an alarm, are registered in the extracted branch circuit. At this time, the center server 22 specifies, for example, the data (power consumption, power consumption) of the device from the past accumulated data and the typical power data of the device, and the power data of the branch circuit of the device. Data may be calculated by subtracting power data. Then, the power data of the selected device may be estimated based on the calculated data.

As described above, the display method of the third embodiment is a display method of displaying information on the display unit 31 of the information terminal 30. Further, the display method includes a step of displaying a target selection screen for selecting any one of one or more devices provided in the facility on the display unit 31. In addition, the display method is one or more candidates consisting of one or more branch circuits presumed to be connected to the selected device based on information on at least one of power consumption and power consumption in the facility. The display unit 31 includes a step of displaying a candidate presentation screen for presenting.

Therefore, the user can easily select the device on the target selection screen, and can confirm one or more branch circuit candidates to which the device selected on the candidate presentation screen is connected. Therefore, the user can associate the branch circuit with the device based on the branch circuit candidate.

Further, on the candidate presentation screen, information regarding at least one of the power consumption and the power consumption of one or more candidates may be displayed.

When only one device is operating at a specific time among the devices connected to the branch circuit, the power consumption information of the branch circuit at the specific time matches the power consumption information of the only operating device. Alternatively, one or more devices may be equipped with a measuring instrument that measures at least one of the power consumption and the electric energy consumption of the device. In such a case, the information terminal can display the branch circuit to which the device is connected and the information of at least one of the power consumption and the power consumption amount in each of the one or more devices.

The user can easily obtain information such as the power consumption of the candidate device from the device guide, the Internet, or the like. Therefore, according to this configuration, the user can more accurately associate the branch circuit with the device.

Further, on the candidate presentation screen, information relating the branch circuit and the device may be displayed. Such information may include a branch name given to each branch circuit, for example, "kitchen", "laundry place", "Western room 1" and the like. Alternatively, the information may include information on a trigger (a sharp pulsed electrical signal for stimulating the circuit to jump from one state to another) generated in the power waveform of the extracted branch circuit. At the moment when the selected device is driven or when the drive is stopped, a trigger is likely to occur in the power consumption waveform of the corresponding branch circuit. Therefore, by detecting the trigger, it is easy to determine the device connected to the branch circuit.

According to this configuration, since the information relating the branch circuit and the device is displayed, the user can more accurately associate the branch circuit with the device.

Further, the display unit 31 may further include a step of displaying an execution selection image for selecting whether or not to execute the association between the branch circuit and the device.

According to the above configuration, the procedure for linking the branch circuit and the device can be easily executed by using the execution selection image.

Further, the center server (information output system) 22 has a first input unit for inputting power information regarding at least one of power consumption and power consumption in the facility, and one or more devices provided in the facility. A second input unit for inputting selected device information regarding the selected device is provided. Further, the center server 22 has a specific unit that identifies one or more candidates including one or more branch circuits that are presumed to be connected to the selected device based on the power information and the selected device information. It includes an output unit that outputs a signal including information of one or more candidates.

Therefore, the information terminal 30 can acquire information on one or more candidates consisting of one or more branch circuits presumed to be connected to the selected device from the center server 22, and displays the one or more candidates on the display unit. Can be displayed.

Further, the center server 22 may output a signal including information regarding at least one of the power consumption and the power consumption of one or more candidates.

According to the above configuration, the information terminal 30 can display information regarding at least one of the power consumption and the power consumption amount, and the user can execute a more accurate association procedure.

Further, the center server 22 may output information relating the branch circuit to the device. The information may include, for example, the above-mentioned information on the timing of trigger generation, or may include information on a label (naming) attached to the branch circuit.

According to the above configuration, the information terminal 30 can display the association information, and the user can execute a more accurate association procedure.

In the third embodiment, the case where only one branch circuit candidate exists has been described, but a plurality of branch circuit candidates may exist. In this case, for example, an illustration of the device described with reference to FIG. 7 and a graph relating time and power consumption may be displayed for all of the branch circuit candidates. Then, on the candidate presentation screen, an operation unit that can select one or more candidates from a plurality of branch circuit candidates may be displayed. This operation unit can be easily realized, for example, by displaying an image similar to the image shown by reference number 71 in FIG. 7 for each branch circuit in all candidate branch circuits.

Further, in the third embodiment, the information terminal does not display the advice on the display unit when associating the selected device with the branch circuit, but the information terminal associates the selected device with the branch circuit. At that time, advice may be displayed on the display unit. For example, suppose that the user selects a dishwasher, and the microwave oven is already registered in the extraction branch circuit corresponding to the dishwasher. At this time, the display unit of the information terminal may display a wording meaning that the breaker is likely to be tripped if the microwave oven and the dishwasher are connected to the same circuit. More precisely, when the sum of the maximum power consumption of each device connected to the branch circuit is equal to or greater than the predetermined power (power at which the breaker is tripped), a wording indicating that the breaker is likely to be tripped is displayed. May be good.

It is also assumed that the general power waveform of the selected home appliance does not appear at all, including a part. In this way, when there is no estimated branch circuit candidate, a display indicating that the estimated branch circuit candidate does not exist may be displayed on the candidate presentation screen.

For example, suppose that the corresponding branch circuit was not found when "Yes" was selected and the refrigerator was selected as the device in the image on the target selection screen shown in FIG. 8 (a). In this case, as shown in FIG. 8B, "The branch circuit to which the refrigerator is connected cannot be found" may be displayed on the display unit 31 of the information terminal 30 on the candidate presentation screen.

Further, in such a case, information on the reason why the estimated candidate does not exist may be displayed on the candidate presentation screen.

For example, as shown in FIG. 8B, a reason such as "may not be measured" may be displayed on the candidate presentation screen. For example, when this reason is displayed, the user can know that the branch circuit to which the refrigerator is connected has not been measured for power data. According to this modification, the user can know the reason why the estimated candidate does not exist. Therefore, it is easy for the user to take the following measures.

The center server 22 selects one or more branch circuits including a power consumption portion similar to at least a part of the general power waveform of the selected device based on the power consumption of each branch circuit from the distribution board 10. I explained the case of doing. However, in addition to or instead of its selection, the center server 22 has selected, for example, information obtained from the power consumption of each branch circuit from the distribution board 10 and the model number of the selected device. Candidates for branch circuits may be extracted based on information such as device ratings.

Further, the information terminal may point out an error in the branch circuit name. For example, when the dishwasher is selected as the device, if the extracted branch circuit name is Western-style room 1, a display such as "The name of the branch circuit may be incorrect." Is displayed and the branch circuit is displayed. You may point out the mistake in the name. More precisely, the storage unit of the information terminal may store information in which the names of the branch circuit names that are acceptable for each device are listed. Then, when the branch circuit name extracted for the selected device is not included in the listed branch circuit names, a wording indicating an error in the branch circuit name may be displayed.

In addition, the program that causes the computer to execute the display method of the present disclosure helps the user to link the branch circuit and the device, and sets the environment for receiving the home appliance service at a low cost and time. Needless to say, it is useful for.
