<Measurement information>
The measuring device 400 basically measures the power consumption (unit: W or kW) consumed by the connected electrical device. By integrating the power consumption over a predetermined time, the power consumption amount (unit: Wh or kWh) of the electric device is calculated.

The home controller 100 can display both the power consumption and the power consumption of each electric device. Furthermore, the home controller 100 can display the total power consumption of these electric devices (that is, the power consumption of the entire power system 1) and the breakdown of the power consumption of the power system 1. Note that the home controller 100 may group a plurality of electric devices and display the power consumption and the power consumption for the entire group.

Therefore, for example, an implementation example of measurement information about the corresponding electrical device 200 transmitted from the measuring device 400 is as follows (however, it is not limited to the following example).

(1) The measuring device 400 measures the power consumption in the electric device 200 at a predetermined cycle (for example, every second), and transmits the measured power consumption as measurement information at the same transmission cycle as the measurement cycle.

(2) The measuring device 400 measures the power consumption in the electric device 200 at a predetermined cycle (for example, every second), and is measured between the previous transmission and the current transmission at a transmission cycle longer than the measurement cycle. The plurality of power consumptions are transmitted as measurement information.

(3) The measuring device 400 measures the power consumption in the electric device 200 every predetermined cycle (for example, every second), and is measured between the previous transmission and the current transmission at a transmission cycle longer than the measurement cycle. The average power consumption obtained by averaging the plurality of power consumptions is transmitted as measurement information.

(4) In (2) or (3), transmission is performed after adding the power consumption obtained by integrating a plurality of power consumptions measured from the previous transmission to the current transmission to the measurement information. Furthermore, you may add the average value, minimum value, maximum value, etc. of some power consumption.

Although time information acquired by the measuring device 400 by some means may be added to the measurement information, generally, when the home controller 100 receives the measurement information, the time at that time is acquired from the clock 112, The data is stored in the hard disk 109 in association with the received measurement information.

Any protocol can be adopted for the exchange of measurement information between the home controller 100 and the measuring instrument 400. Typically, a configuration is adopted in which the measuring device 400 broadcasts a packet including its own measurement result, and the home controller 100 receives this packet. However, the home controller 100 may periodically poll each measuring device 400.

Next, each embodiment related to the display of power information by the home controller 100 will be described. Various types of information and data necessary for displaying the screen described below are stored in the hard disk 109 or an external server. Hereinafter, the hard disk 109 that is a data storage location or an external server is collectively referred to as “hard disk 109”.

The CPU 101 controls the display 103 using information stored in the hard disk 109. Thereby, a screen described below is displayed on the display surface of the display 103.

FIG. 6 is a diagram illustrating display on home controller 100 according to the first embodiment. Referring to FIG. 6, home screen 500 includes a calendar display area 501, a month display area 502, a scroll button display area 503, and a current day information display area 504.

In the calendar display area 501, the calendar is displayed in a table format. By default, the calendar for this month is displayed in the calendar display area 501.

In the month display area 502, the year and month of the calendar displayed on the home screen are displayed. The scroll button display area 503 displays a plurality of buttons for changing the displayed calendar. These buttons are operated by the user. Specifically, in the scroll button display area 503, a current month button 503a, a next month move button 503b, a last month move button 503c, a next year move button 503d, and a last year move button 503e are displayed.

In the current day information display area 504, information on today is displayed. If information related to the schedule of the day is registered, the schedule is also displayed in the current day information display area 504. The schedule may be scroll-displayed in the day information display area 504. When a calendar of a month different from the current month is displayed, nothing is displayed in the current day information display area 504.

The calendar is displayed in the form of a two-dimensional table (a table with dates arranged vertically and horizontally). Therefore, the calendar display area 501 includes a plurality of date display areas 510 arranged two-dimensionally. FIG. 6 shows an example in which the current day (today) is December 25, 2012. In order to show the date display area 510 corresponding to the current day, for example, the display area is surrounded by a bold frame.

The background color is set in the date display area 510 corresponding to the day before the previous day. The background color represents performance information indicating the power saving performance on that day. That is, the date display area 510 corresponding to the day before the previous day is painted in a color indicating the record information. The term “before the previous day” includes the previous day. The term “after that day” includes that day.

On the other hand, the background color of the date display area 510 corresponding to the day from the current day to the end of the month is set to, for example, white. Further, the background color of the display area corresponding to the date of the month other than the current month (November 2012 and January 2013 in the example of FIG. 5) is, for example, gray.

In the example shown in FIG. 6, the date display area 510 is color-coded based on the performance information for each of a plurality of dates from December 1, 2012 to December 24, 2012. The performance information indicates the degree (level) of power saving. In this embodiment, the performance information is defined as the ratio of the actual power consumption to the power consumption reference. In FIG. 6 and the drawings described below, the background color is expressed by hatching. Different hatching means different colors.

In this embodiment, there are four background colors indicating the degree of power saving: green, yellow-green, yellow, and red. As for each background color, green indicates the highest degree of power saving. Red indicates the lowest power saving level.

各 Each background color is associated with a power saving level (result information value). For example, green indicates that the degree of power saving is 15% or more. Yellow-green indicates that the degree of power saving is 5% or more and less than 15%. Yellow indicates that the degree of power saving is -5% or more and less than 5%. Red indicates that the degree of power saving is less than -5%. In the example shown in FIG. 6, the background color of the display area 510a (December 6, 2012) is green, the background color of the display area 510b (December 8, 2012) is yellow-green, and the display area The background color of 510c (December 7, 2012) is yellow, and the background color of the display area 510d (December 15, 2012) is red.

The above background color types, the number of background colors, and the like are merely examples, and do not limit the present invention. However, when the number of background colors increases, it becomes difficult for the user to see the calendar, and thus it is difficult for the user to understand the difference in the degree of power saving for each day. In addition, when the number of background colors decreases, the degree of power saving can only be roughly indicated, which may weaken the effect of encouraging the user to save energy. The number of background colors and the association between the background color and the degree of power saving are set in consideration of these points, for example.

The standard for calculating the degree of power saving (result information) can be set by various methods. Examples of power consumption standards are given below. Only one of the following examples may be adopted, and the reference may be arbitrarily changed by the user.

In one example, a target value is input by a user, for example. This target value is the reference power consumption.

In another example, the past performance is set as the reference power consumption. For example, performance information on the same day of the same week of the same month of the previous year is set as the reference power consumption.

”In the previous year and this year, the corresponding day of the week is shifted. Therefore, for example, even if today is a weekday (for example, Monday), the same day of the previous year may be a holiday (for example, Sunday). For reasons such as lifestyle, there is a possibility that a difference is likely to occur between Sunday and Monday depending on the amount of power consumption. In this embodiment, the performance information on the same day of the same week of the same month of the previous year is set as the reference power consumption. Thereby, power consumption can be compared on the premise of the use condition of the same electric equipment.

In yet another example, the actual power consumption of a household having a similar family structure can be used as the reference power consumption. For example, the power consumption of the home where the power system 1 is installed is collected in an external server. The home controller 100 accesses an external server, and acquires, for example, power consumption data of a home having a similar family structure in the same region. This data is used as a reference power consumption. More preferably, the average power consumption of a plurality of households is set as the reference power consumption.

In the date display area 510, a weather icon 512 is displayed. The weather icon 512 indicates the weather of the day corresponding to the date display area 510 where the weather icon 512 is arranged. When weather information is input in an action log application (described later), a weather icon 512 corresponding to the information is displayed in the date display area 510. On the other hand, when weather information is not input to the action log application, a weather icon 512 corresponding to the weather forecast information is displayed in the date display area 510.

A weather icon 512 corresponding to the weather forecast information is displayed in the display area of the date on and after that day. The user inputs weather information for dates before the previous day to the home controller 100. When the weather information is input to the home controller 100, the weather forecast information is updated to the information input by the user.

Furthermore, when the user selects a date display area 510 corresponding to a date before the previous day and inputs a log using the action log application, a log icon 514 is displayed in the date display area 510 corresponding to the date. When the user selects a date display area 510 corresponding to a date after the current day and inputs a schedule for that day in advance, a schedule icon 516 is displayed in the date display area 510 corresponding to that date.

According to the first embodiment, the calendar is displayed in different colors according to the power saving performance of the day. By expressing the degree of power saving by color, it is possible to visually impress the user on the results of power saving. Furthermore, the user can easily grasp the transition of the degree of power saving.

The following describes multiple examples of calendar color-coding patterns. FIG. 7 is a diagram showing a color-coding pattern of a calendar when the power saving effect is high. FIG. 8 is a diagram showing a color-coded pattern of the calendar when the power saving effect is moderate. FIG. 9 is a diagram showing a color coding pattern of a calendar when the power saving effect is low.

7 to 9, when the power saving effect is high (when there are many days when the power saving performance is high), the green display area and the yellow-green display area are relatively large. On the other hand, when the power saving effect is low, the yellow display area and the red display area are relatively increased. By showing the user that there are many yellow display areas and red display areas, for example, the user can be given an opportunity to work on power saving. By indicating that there are many green display areas and yellow-green display areas, it is possible to prompt the user to continue the power saving efforts. Therefore, the user's interest in energy saving can be increased and the interest can be maintained.

Furthermore, in the date display area 510, an icon indicating the weather information (weather icon 512) is displayed. Thereby, the user can know the correlation between the performance of power saving and the weather. Therefore, the user can work to increase the power saving degree (or maintain a high degree of power saving) in consideration of the weather information (weather forecast) of today or tomorrow. The weather information is not limited to the weather of the day such as sunny or rainy, and may include other information related to the weather. For example, in addition to the weather, the highest temperature and the lowest temperature of the day may be displayed in the date display area 510.

In addition, the calendar is displayed on the home screen. Since the user confirms today's date or schedule, it is considered that there are relatively many opportunities for the user to view the calendar. In this embodiment, when the user confirms the schedule, the user can intuitively grasp the results of power saving. Thereby, the effect of prompting the user to save power can be achieved.

FIG. 10 is a diagram for explaining the screen transition of the home controller 100. Referring to FIG. 10, the home screen 500 can transition to a past log screen 600, an action log screen 700, and a schedule screen 800. The past log screen 600, the action log screen 700, and the schedule screen 800 may be able to transition to each other without going through the home screen 500.

The calendar shown in FIG. 6 is displayed on the home screen 500. The past log screen 600 is a screen for browsing information (hereinafter also referred to as “log”) and power data recorded by the user. When there is no log record, only the power data for the day is displayed on the past log screen 600.

The action log screen 700 is a screen for the user to enter a log. A user inputs a log into the action log screen 700 using the action log application. The input log is stored in, for example, the hard disk 109 (see FIG. 3) and displayed on the past log screen 600.

The schedule screen 800 is a screen for the user to enter a schedule. The entered schedule is stored in, for example, the hard disk 109 (see FIG. 3) and displayed on a browsing schedule screen.

When the user selects a date on the calendar displayed on the home screen 500, the home screen 500 changes to the past log screen 600, the action log screen 700, or the schedule screen 800. The operation for changing the screen is not particularly limited.

For example, when the user touches the log icon 514, the home screen 500 changes to the past log screen 600. For example, when the user touches the schedule icon 516, the home screen 500 changes to the schedule screen 800. These operations correspond to date selection by the user. For example, when the user touches the date display area 510 of the date before the previous day for a long time, the home screen 500 transitions to the action log screen 700.

The operation for returning to the home screen 500 from the screen after the transition is not particularly limited. For example, when there is no user operation on each screen for a predetermined time or longer, the display 103 of the touch panel 102 is temporarily hidden to save power. Next, when the user operates the tablet 104, the screen of the display 103 changes from the original screen to the home screen 500.

Alternatively, a home button may be arranged on each screen, and when the user operates the home button, transition from the original screen to the home screen 500 may be performed. Alternatively, when the user operates the operation button 105 illustrated in FIG. 3, the screen may transition from the current screen to the home screen 500.

In this specification, the screen on which the calendar is displayed is called the “home screen”. The name of the screen on which the calendar is displayed is not limited. For example, a screen similar to the home screen may be called a “top screen”. The “home screen” may be a screen that is first displayed on the home controller 100 when the user logs in, for example.

Next, each screen transitioned from the home screen will be described.
FIG. 11 is a diagram illustrating an example of a past log screen. Referring to FIG. 11, past log screen 600 includes a date display area 602, log display area 604, weather display area 606, electric energy data display area 608, and action log display area 610.

In the date display area 602, the date (year / month / day) selected in the calendar is displayed. A one-line diary is displayed in the log display area 604. A one-line diary is a text with a small number of characters (including pictograms) of about one line. The user inputs a one-line diary through an action log screen (described later). The inputted one-line diary (that is, log) is displayed in the log display area 604. In the weather display area 606, weather information for the day is displayed as an icon, for example. The weather information may be displayed by characters.

In the power amount data display area 608, the power consumption amount per hour of the date selected on the calendar is displayed in a graph. For example, a bar graph shows the power consumption per hour and the breakdown of the power consumption. Furthermore, the change of the power consumption per hour of the entire power system 1 is shown by a line graph.

The electrical device shown in the graph is an electrical device to which the measuring device 400 is attached. Information regarding the power consumption of the electric device is sent to the home controller 100 through the measuring device 400. The home controller 100 collects information from the measuring device 400. This information is stored in, for example, the hard disk 109 or an external server. When the past log screen is called, the home controller 100 (CPU 101) displays the power consumption amount in a graph based on the information.

In the action log display area 610, the action of the day selected on the calendar and the time zone of the action are displayed. The time zone is color-coded according to the type of action.

Further, when the user selects a plurality of date display areas 510 respectively corresponding to a plurality of dates in the calendar, the home screen transitions to a past log screen corresponding to those dates. For example, when the user touches a plurality of date display areas 510 at the same time (multi-tap), the home screen changes to a past log screen. In the past log screen, power data for a plurality of dates is represented by a graph.

FIG. 12 is a diagram showing an example of a past log screen when a plurality of dates are selected by the user. Referring to FIG. 12, for example, two different dates (December 9, 2012 and December 15, 2012) are selected by the user. The past log screen 600 has a power amount data display area and an action log display area corresponding to the selected date. Specifically, the past log screen 600 includes power amount data display areas 608a and 608b and action log display areas 610a and 610b.

The electric energy data display area 608a and the action log display area 610a display the electric power consumption data and the action of one of the two selected dates (for example, December 9, 2012). The power amount data display area 608b and the action log display area 610b display the power consumption amount data and actions of the other of the two selected dates (for example, December 15, 2012).

In addition, in FIG. 12, the example of the past log screen in case the number of the selected dates is two is shown. However, the number of selectable dates is not limited to 2, and may be 3 or more.

Thus, in this embodiment, when the user selects an arbitrary past date on the calendar, the home screen transitions to a past log screen corresponding to the selected date. On the past log screen, the power amount data, the action log, and the weather information corresponding to the selected date are displayed. The user can associate the power saving degree of a certain day in the past with the behavior of the day. Thus, the user can analyze the cause of the degree of power saving achieved that day. For example, the user can grasp that a long time of going out is a cause of an increase in the degree of power saving. Alternatively, when the degree of power saving is low despite going out or sleeping, the user determines that, for example, the appliance is moving while going out or sleeping is the cause of the decrease in the degree of power saving. Can do.

Furthermore, in this embodiment, when the user selects a plurality of past dates on the calendar, power amount data corresponding to the selected plurality of dates is displayed on the past log screen. For example, the user can analyze the reason why the degree of power saving is low by comparing a day with a high degree of power saving with a day with a low degree of power saving. Moreover, it is possible for the user to analyze common factors that lead to a decrease in the degree of power saving, for example, by selecting two days with a low degree of power saving. Conversely, the user can analyze common factors that improve the power saving degree, for example, by selecting two days with a high power saving degree. These analyzes allow the user to spend a more energy-saving life.

Furthermore, according to this embodiment, a log icon 514 indicating registration of a past log (one-line diary) is displayed in the date display area 510 of the calendar. Thereby, the user can grasp whether or not an event on a certain past date is recorded as a one-line diary.

Even when the log icon 514 is not displayed (one-line diary is not registered), the past log screen is called by selecting a calendar date, and the power corresponding to the date is displayed. Quantity data is displayed on the past log screen.

FIG. 13 is a diagram showing an example of an action log screen. Referring to FIG. 13, action log screen 700 includes a date display area 702, a log recording area 704, a weather recording area 706, and an action display area 720.

In the date display area 702, the date selected from the calendar is displayed. Note that the date of the action log may be changed by the user operating the date display area 702 after the action log screen 700 is called.

The log recording area 704 is an area for the user to freely record contents.
The weather recording area 706 is an area for the user to record the weather. In the example shown in FIG. 13, weather information is recorded in the weather recording area 706 by characters. However, weather information may be recorded by selecting an icon. In this case, the selected icon is displayed in the weather recording area 706. In the weather display area 606 of the past log screen 600, icons corresponding to the weather information recorded in the weather recording area 706 are displayed. When weather information is recorded in the weather recording area 706 by characters, for example, icons displayed in the weather display area 606 of the past log screen 600 based on weather-related keywords such as “sunny”, “cloudy”, and “rain”. Is determined.

The action display area 720 is an area for displaying the user's action on the selected day. The user operates various buttons arranged on the action log screen 700 to record the action. In the example shown in FIG. 13, an outing button 708, a washing button 710, a cooking button 712, a washing button 714 and a cleaning button 716 are arranged on the action log screen 700. When the user selects the outing button 708, the outing marker 721 and the return home marker 722 are displayed at default positions in the action display area 720. The user inputs an outing period by sliding one or both of the outing marker 721 and the return home marker 722.

Similarly, when the user selects the washing button 710, the cooking button 712, the washing button 714, and the cleaning button 716, the washing marker 723, the cooking marker 724, the tableware marker 725, and the cleaning marker 726 are displayed, respectively. “Laundry” means washing clothes, and “washing” means washing dishes. A user slides the marker corresponding to each action, and records the action of the day. The marker can be moved to positions corresponding to, for example, 0 minutes, 15 minutes, 30 minutes and 45 minutes every hour.

Furthermore, an end button 732 and a registration button 734 are arranged on the action log screen 700. When the user operates the end button 732, the action log application ends. Before exiting, you will be asked if you want to save the recorded content. When saving the recorded contents, the user operates the registration button 734. As a result, the content recorded on the action log screen is stored in the external server or the hard disk 109.

FIG. 14 is a diagram showing an example of the schedule screen 800. When the user touches the schedule icon 516, the schedule screen 800 is called. The schedule icon 516 is displayed in the date display area 510 corresponding to today and the following days.

Referring to FIG. 14, the schedule screen 800 has a date display area 802 and a schedule display area 804. In the date display area 802, the selected date is displayed.

The schedule display area 804 includes a time display area 806, a user display area 808, a schedule display area 810, and an icon display area 812. In the time display area 806, the scheduled time is displayed. The schedule screen 800 is a screen for browsing the schedule.

In the user display area 808, the schedule registrant is displayed. The displayed name is, for example, a user name registered in the power system 1.

In the schedule display area 810, the schedule edited and registered in the schedule editing screen (described later) is displayed. In the icon display area 812, icons registered on the schedule edit screen are displayed.

A plurality of schedules are displayed in order from the top to the bottom of the schedule display area 804 in the order from the earliest scheduled time. When the user touches the area where the schedule is displayed, the schedule edit screen is called up. It should be noted that the schedule edit screen is also called when a calendar date (today and later) on which the schedule icon 516 is not displayed is selected.

FIG. 15 is a diagram showing an example of a schedule edit screen. Referring to FIG. 15, schedule edit screen 800 </ b> A includes a date display area 822, a schedule recording area 824, a start time entry area 826, an writer registration area 828, and an icon registration area 832.

In the date display area 822, the selected date is displayed. In the schedule recording area 824, the schedule is written in text.

In the start time entry area 826, the scheduled start time of the schedule is entered.
In the registrant registration area 828, a schedule writer is registered. The writer may be selected from user names registered in the power system 1.

In the icon registration area 832, an icon corresponding to the person who entered the schedule is registered. For example, an icon associated with the user name is called to the icon registration area 832. If there is no icon associated with the user name, a default icon is registered.

Furthermore, a registration button 842 and a cancel button 844 are arranged on the schedule edit screen 800A. When the user operates the registration button 842, the content recorded on the schedule edit screen 800A is stored in the external server or the hard disk 109. When the user operates the cancel button 844, the content recorded on the schedule edit screen 800A is discarded. Note that after the operation of the registration button 842 and the cancel button 844, for example, the schedule editing screen 800A transitions to the schedule screen 800 (schedule browsing screen).

<Display processing of home controller 100>
FIG. 16 is a flowchart illustrating display processing of home controller 100 according to the first embodiment. This processing is mainly performed by the CPU 101 in cooperation with the display 103 or the like based on data stored in the memory 110 and the hard disk 109. The same applies to the flow described below.

Referring to FIG. 16, first, in step S2, CPU 101 determines a period displayed by a calendar. For example, the CPU 101 acquires information about today's date. Based on the information, the CPU 101 determines this month as a period displayed by the calendar. When the operation button arranged in the scroll button display area 503 is operated by the user, the CPU 101 determines a display period (for example, a period of one month corresponding to the previous month) according to the operation.

In step S4, the CPU 101 acquires information on the degree of power saving. For the days before today within the period determined in step S <b> 2, the CPU 101 acquires information on the degree of power saving from the hard disk 109. For example, the hard disk 109 stores a reference power consumption value and an actual power consumption value. The CPU 101 acquires those values from the hard disk 109 and calculates the power saving degree. As a result, the CPU 101 acquires information on the degree of power saving (that is, performance information).

In step S6, the CPU 101 executes a calendar display process based on the acquired power saving degree information.

FIG. 17 is a flowchart illustrating the calendar display process shown in FIG. Referring to FIG. 17, in step S12, CPU 101 determines the background color of date display area 510 of each day based on the power saving degree. As described above, four colors of green, yellowish green, yellow, and red are prepared in advance as background colors. Each color is associated with a power saving degree value. The CPU 101 determines a background color corresponding to the power saving degree from the above four colors.

In step S14, the CPU 101 acquires weather information. The CPU 101 acquires the weather information for today and the following days from the weather forecast. On the other hand, the CPU 101 acquires weather information for the previous day and previous days from information registered in the past log.

In step S16, the CPU 101 determines the weather icon 512 displayed in the date display area 510 of each day based on the acquired weather information.

In step S18, the CPU 101 determines whether there is a past log on the previous day and the previous day. In step S20, the CPU 101 determines the date on which the log icon 514 is displayed. If it is determined that there is a past log for a certain date, the CPU 101 determines to place the log icon 514 in the display area for that date. On the other hand, if there is no past log for a certain date, the CPU 101 determines not to place a log icon in the display area for that date.

In step S22, the CPU 101 determines whether or not there is a schedule for today and the following day. In step S24, the CPU 101 determines the date on which the schedule icon 516 is displayed. Since the processes in steps S22 and S24 are the same as the processes in steps S18 and S20, detailed description thereof will not be repeated.

In step S26, the CPU 101 displays each day on the display 103. The date display area 510 of each day is displayed with the background color determined by the process of step S12. Further, in each date display area 510, a weather icon 512 determined by the process of step S16 is arranged. Further, when there is a registered past log or registered schedule, a log icon 514 or a schedule icon 516 indicating the registered past log or schedule is displayed in the corresponding date display area 510.

Note that the processing order of steps S12 to S24 is not limited as shown in FIG. The order of these processes may be changed as appropriate. Alternatively, a plurality of processes may be executed in parallel.

As described above, according to the first embodiment, the CPU 101 obtains performance information (power saving degree information) indicating the power saving performance of the electrical device on the day displayed on the calendar. The CPU 101 displays the display area of the display 103 corresponding to each day of the calendar in a display color corresponding to the record information among the plurality of display colors. Thereby, the user can visually impress the degree of power saving. Further, the power saving degree for each day is displayed on the display 103 as a color distribution. Thereby, the user can be prompted to save power.

Furthermore, it can be expected that the user has many opportunities to see the calendar. The power saving results are displayed in association with the calendar. Therefore, the user's interest in the degree of power saving can be continued.

[Embodiment 2]
The second embodiment is different from the first embodiment in the configuration of the screen on which the calendar is displayed. Since the configuration of the power system is the same as that of the first embodiment, the following description will not be repeated.

FIG. 18 is a diagram for explaining the display of the home controller 100 according to the second embodiment. 6 and 18, home screen 500 according to the second embodiment is configured as a launcher screen. Specifically, home screen 500 according to the second embodiment includes operation button display area 520 and message display area 530 in addition to the configuration shown in FIG.

Referring to FIG. 19, home screen 500 includes a display area 550 for displaying a calendar, a past log, an action log, and a schedule. The screen of each application is displayed in the display area 550 in accordance with the screen transition shown in FIG. When the user operates the graph display button 522, a past log screen is displayed in the display area 550. Similarly, when the user operates each of the calendar display button 524, the action log button 526, and the schedule button 528, the screen of the corresponding application is displayed in the display area 550.

In the second embodiment, the same calendar display process as in the first embodiment is executed. Therefore, according to the second embodiment, as in the first embodiment, the degree of power saving can be visually impressed on the user.

[Embodiment 3]
In the first and second embodiments, the power saving degree of each day is expressed by the background color of the calendar. In the third embodiment, the power saving degree of each day is displayed in a manner different from the display according to the first and second embodiments. Since the configuration of the power system is the same as that of the first embodiment, the following description will not be repeated.

FIG. 20 is a diagram for explaining the display of the home controller 100 according to the third embodiment. With reference to FIG. 6 and FIG. 20, four types of symbols, double circle, single circle, triangle, and cross (x), are displayed in the display area of each day as symbols indicating the degree of power saving. A double circle indicates that the power saving degree is the highest, and a cross (x) indicates that the power saving degree is the lowest.

The symbol shown in FIG. 20 is an example for expressing the degree of power saving. The expression method of the power saving degree is not limited in this way.

Furthermore, the calendar display format may be switchable between a two-dimensional table and a one-dimensional table.

In this embodiment, a calendar for one month is displayed. However, a one-week calendar may be displayed, and the display may be switchable between a one-month calendar and a one-week calendar. Furthermore, when displaying a calendar for one month, the user may be able to set the start date and / or end date of the month.

Even in each of these examples, the date display area of each day is displayed in a manner corresponding to the degree of power saving. For example, as in the first and second embodiments, the date display area is displayed with a background color corresponding to the degree of power saving. Alternatively, as in the third embodiment, the date display area is displayed in a display mode (for example, a symbol) other than the background color.

In each of the above embodiments, both the management device and the display device of the present invention are realized by the home controller. However, the display device of the present invention is not limited to the home controller. For example, the display device of the present invention may be realized by a mobile terminal (for example, a smartphone) having a display function. An application for performing display according to each of the above embodiments is downloaded from an external server and installed on a smartphone. Thereby, the smart phone can implement | achieve the display apparatus of this invention. The smartphone obtains information related to power consumption by accessing a device in which measurement information of power consumption is stored, and performs display according to each of the above embodiments.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
