In addition, a time period in which the home appliance is used at least within a certain period (one week in the example of FIG. 7) is denoted as “B”, and a time period when the home appliance is not used within a certain period is denoted as “C”. In the example of FIG. 7, assumed power consumption patterns are shown for each time zone for televisions, air conditioners, lighting, and the like. For example, the power consumption pattern of the refrigerator is “A” in all time zones, and it is assumed that the refrigerator is continuously operated without being turned off every day.

<3 operation>
Next, the operation of the display device 30 will be described with reference to FIGS. FIG. 8 is a flowchart illustrating a process in which the CPU 37 of the display device 30 determines whether the setting of the association between the tap 20 and the home appliance indicated in the tap connection setting information 100 is appropriate. CPU37 specifies the kind of apparatus connected to the tap 20, based on the tap connection setting information 100, and compares with the threshold value of the power consumption defined for every apparatus. That is, a threshold value of power consumption is set for each home appliance, and if the device connected to the tap 20 exceeds this threshold value, it is determined that the setting for associating the tap 20 with the device is an error. Furthermore, the CPU 37 compares the device connected to the tap 20 with the power consumption pattern for each device, and determines whether the setting of the association between the tap 20 and the device is appropriate according to the degree of coincidence with the power consumption pattern.

  In step S <b> 103, the CPU 37 initializes a tap ID to be determined in order to determine whether each tap indicated by the tap ID 101 of the tap connection setting information 100 is sequentially matched with the home appliance.

  In step S <b> 105, the CPU 37 reads out the type of device connected to the tap from the home appliance ID 102 for the determination target tap. The CPU 37 refers to the power consumption history information 110 and reads the power consumption amount of the device connected to the tap from the power consumption amount 112.

  In step S107, the CPU 37 compares the threshold value of power consumption determined for each type of device read in step S105 with the maximum value indicated in the history of power consumption stored in the power consumption 112. In this history, it is determined whether the maximum value of power consumption is equal to or less than the above threshold.

  If the maximum value of power consumption is not less than or equal to the above threshold value (exceeds the threshold value) (NO in step S107), CPU 37 executes the process of step S119, and the tap and home appliance indicated in tap connection setting information 100 Is determined to be incorrect. When the maximum value of power consumption is equal to or less than the above threshold value (YES in step S107), CPU 37 executes the process of step S109.

  In step S109, the CPU 37 refers to the tap connection setting information 100, acquires the type of device associated with the determination target tap from the home appliance ID 102, and acquires the acquired power consumption pattern of the device from the power consumption pattern information 120. read out. For example, in the example of FIG. 5, when the tap ID of the determination target tap is “1”, the CPU 37 sets the home appliance type corresponding to the tap ID “1” of the tap ID 101 (the home appliance ID 102 is “22”). , A device whose home appliance name 103 is “microwave oven”) and the home appliance ID 102. The CPU 37 reads out the power consumption pattern of the device whose home appliance ID is “22” and the home appliance name is “microwave oven” from the home appliance name 122.

  In step S111, based on the power consumption history information 110 and the power consumption pattern information 120, the CPU 37 compares the power consumption history of the devices connected to the tap with the power consumption pattern for each time slot. As a result of executing this comparison for each time zone, the CPU 37 calculates the coincidence ratio between the history of power consumption and the pattern of power consumption.

  In step S113, it is determined whether or not the calculation result in step S111 (the matching ratio between the power consumption history and the power consumption pattern) is equal to or greater than a threshold (for example, matches 80% or more). In step S113, when the coincidence ratio between the power consumption history and the power consumption pattern is equal to or greater than the threshold (YES in step S113), the CPU 37 executes the process of step S117. In step S113, when the coincidence ratio between the power consumption history and the power consumption pattern is not equal to or greater than the predetermined threshold (NO in step S113), the CPU 37 executes the process of step S115.

  In step S115, the CPU 37 determines whether or not the power consumption history information 110 has sufficient power consumption history stored for the determination target tap (for example, data for 7 days or more is recorded). . In step S115, when the power consumption history is not sufficiently stored in the power consumption history information 110 (NO in step S115), the CPU 37 executes the process of step S117. In step S115, when the power consumption history information 110 is sufficiently stored in the power consumption history information 110 for the determination target tap (YES in step S115), the CPU 37 executes the process of step S119 to determine the determination target tap. About a tap, it determines with the setting of matching with the tap and household appliances which are shown in the tap connection setting information 100 being an error.

  In step S117, the CPU 37 determines that the setting for associating the determination target tap with the device connected to the tap indicated in the tap connection setting information 100 is appropriate.

In step S121, the CPU 37 updates the determination target tap.
In step S123, the CPU 37 determines whether the determination process has been executed for all the determination target taps based on the update result in step S121. If there is an undetermined tap in step S123 (NO in step S123), CPU 37 executes the process of step S105. In step S123, when determination processing has been completed for all the determination target taps (YES in step S123), the CPU 37 executes processing in step S125.

  In step S <b> 125, the CPU 37 displays a possibility that the tap setting is incorrect on the display 38 for the tap that is determined to have an incorrect association setting between the tap and the home appliance shown in the tap connection setting information 100. Notify the user. A display example of step S125 will be specifically described.

  FIG. 9 is a diagram illustrating a display example in which the display device 30 displays the confirmation of the setting of the association between the tap and the home appliance on the display 38. As illustrated in FIG. 9, the CPU 37 displays in the message display area 81 a possibility that the setting of the association between the tap and the home appliance is incorrect and a guidance message for prompting the user to change the setting of the association. .

  The selection area 82 is an area for displaying a tap in which the setting of the association between the tap and the home appliance is determined to be incorrect in step S119. For example, referring to the tap connection setting information 100 and the power consumption history information 110, “tap 1” is associated with a microwave oven, and power is consumed over all time zones. The “tap 2” is associated with a refrigerator, and power is consumed only during a certain time period. On the other hand, referring to the power consumption pattern information 120, the refrigerator consumes power over all time zones, and the microwave oven has a limited time zone during which power is consumed. Therefore, in step S119, the CPU 37 determines that the setting of association between “tap 1” and “tap 2” and the home appliance is an error. The CPU 37 displays that the setting of association with the home appliance is determined to be incorrect for “tap 1” in the selection area 82A and “tap 2” in the selection area 82B.

  The setting change button 83 is an area for accepting an operation for changing the setting of a tap for which it is determined that the setting of the association between the tap and the home appliance is incorrect. The unchangeable button 84 is an area for accepting an operation that does not change the tap setting from the user. Note that when the CPU 37 receives an operation that does not change the tap setting using the unchangeable button 84, the CPU 37 may not notify the possibility that the setting is incorrect thereafter.

  Next, the operation of the CPU 37 for facilitating the setting of the correspondence between the tap and the home appliance by the user by notifying the user of the home appliance candidate to be connected to the tap will be described using FIG. . FIG. 10 is a flowchart illustrating a process of notifying a user of a device candidate connected to a tap.

For example, based on the power consumption history information 110 and the power consumption pattern information 120, the CPU 37 compares the power consumption amount history of the device and the power consumption pattern of each home appliance for each time slot. As a result of executing this comparison for each time zone, the CPU 37 calculates a matching rate between the history of power consumption and the power consumption pattern, and extracts the home appliance having the highest matching rate.

  In step S <b> 211, as a result of the processing in step S <b> 209, the CPU 37 has a matching ratio equal to or higher than a threshold (for example, 80% or higher) for the home appliance having the highest matching ratio between the power consumption history and the power consumption pattern. ). When the coincidence ratio between the power consumption history and the power consumption pattern is equal to or greater than the threshold (YES in step S211), the CPU 37 executes the process of step S213, and selects the home appliance corresponding to the power consumption pattern. , And memorize as a candidate for home appliances connected to the tap. When the coincidence ratio between the power consumption history and the power consumption pattern is not equal to or greater than the threshold (NO in step S211), the CPU 37 executes the process of step S215 and stores that the candidate of the device connected to the tap is unknown. To do.

In step S217, the CPU 37 updates the determination target tap.
In step S219, the CPU 37 determines whether the determination process has been executed for all the determination target taps based on the update result in step S217. If there is an undetermined tap (NO in step S219), CPU 37 executes the process of step S205. When the determination process has been completed for all the determination target taps (YES in step S219), CPU 37 executes the process of step S221.

  In step S <b> 221, the CPU 37 notifies the user of the tap in which the candidate for the home appliance connected to the tap is stored in the process of step S <b> 213 by displaying the candidate on the display 38 for each tap.

  FIG. 11 is a diagram illustrating a display example of the display 38 for the display device 30 to notify the user of a device candidate connected to the tap. As shown in FIG. 11, when the setting of the device connected to the tap is determined to be incorrect, the CPU 37 recommends a device candidate and displays a guidance text for accepting a setting change operation from the user in the message display area. 91.

  The selection area 92 is an area for displaying candidate devices connected to the tap by the process of step S221. In the change target display area 95, the CPU 37 displays a tap for which it is determined that the association setting of the device connected to the tap is incorrect. In the example of FIG. 11, the CPU 37 displays “tap 1” in the change target display area 95A and “tap 2” in the change target display area 95B. CPU37 displays the household appliances memorize | stored as a candidate of the apparatus connected to a tap by the process of step S213 in the household appliance candidate display area 97. FIG. In the example of FIG. 11, the CPU 37 displays a candidate for a device connected to “tap 1” in the home appliance candidate display area 97A, and displays a candidate for a device connected to “tap 2” in the home appliance candidate display area 97B. .
