Hereinafter, “user of customer facility 5” is also simply referred to as “resident”.

  Moreover, the information terminal device 1 is connected to the determination system 30 via the network 4 as shown in FIG. The determination system 30 is a system that determines whether or not the power consumption for a specific circuit of the customer facility 5 is greater than or equal to a threshold value.

  Based on the measurement value measured by the measurement system 20, the information terminal device 1 causes the display unit 11 to display usage information indicating the power usage status for the specific circuit. Thereby, the display system 10 of this embodiment can present the information (usage information) showing the usage condition of the electric power in the customer facility 5 to the customer who is the owner of the information terminal device 1. . That is, the customer can visually confirm the power usage status in the customer facility 5 by looking at the screen displayed on the display unit 11.

  Furthermore, the information terminal device 1 displays the unit price information on the display unit 11 together with the usage information. The “unit price information” here is information representing the unit price of the electricity charge applied to the customer facility 5. In the present embodiment, it is assumed that the unit price of the electricity bill applied to the customer facility 5 is not the same throughout the day, but varies depending on the time zone. However, it is not essential that the unit price of the electricity rate varies depending on the time zone, and this embodiment is applicable even when the unit price of the electricity rate is the same throughout the day, or when the unit price of the electricity rate varies depending on the day of the week or the season. Is possible.

  Then, the information terminal device 1 displays the above-described usage information and unit price information in time series on the screen of the display unit 11 in association with each time zone.

Unit price information indicating the unit price of the applied electricity bill is displayed together. Moreover, the usage information and the unit price information are displayed in time series in association with each time zone. Therefore, the customer can also confirm the unit price of the electricity bill in each time zone when confirming the power usage status in the specific circuit. That is, the customer can check the usage status of the power in the specific circuit from the screen displayed on the display unit 11 in association with the unit price of the electric charge for each time zone. As a result, the customer can make a use plan of the equipment so as to keep the electricity bill low by, for example, so-called time shift that shifts the equipment usage time zone to a time zone where the unit price of the electricity bill is low.

  The customer who receives the service provided by the display system 10 (the owner of the information terminal device 1) may be the same person as the resident (user of the customer facility 5), or lives away from the resident, for example. The relative may be a different person from the resident.

(2) System Configuration Next, the configuration of the display system 10, the measurement system 20, and the determination system 30 according to the present embodiment will be described.

(2.1) Display System First, the configuration of the display system 10 of the present embodiment will be described with reference to FIGS. 1 and 2. In the present embodiment, the display system 10 is configured by the information terminal device 1 as described above.

  The information terminal device 1 is a smartphone including the display unit 11 as an example. The information terminal device 1 has a computer having a CPU (Central Processing Unit) and a memory as a main component, and causes the computer to function as the display control unit 12 when the CPU executes a program stored in the memory. Here, the program is provided through an electric communication line such as the Internet or recorded in a recording medium such as a memory card, but may be recorded in advance in a memory of a computer. The display control unit 12 here has a function of creating a screen to be displayed on the display unit 11 and controlling the display unit 11 to display the created screen on the display unit 11. That is, the information terminal device 1 including a smartphone implements a function as the display control unit 12 for controlling the display unit 11 by installing dedicated application software and starting the application software.

  The information terminal device 1 further includes a communication unit 13, an input unit 14, and a storage unit 15 in addition to the display unit 11 and the display control unit 12.

  The communication unit 13 is connected to the network 4 to enable communication between the information terminal device 1, the measurement system 20, and the determination system 30. Here, since the information terminal device 1 is a smartphone, the communication unit 13 is connected to the network 4 made of the Internet, for example, via a mobile phone network (carrier network) provided by a communication carrier. Examples of the mobile phone network include a 3G (third generation) line and an LTE (Long Term Evolution) line. The communication unit 13 may be connected to the network 4 via a public wireless LAN (Local Area Network).

  The input unit 14 has a function of accepting an operation of a customer (owner of the information terminal device 1). In the present embodiment, the information terminal device 1 is a smartphone equipped with a touch panel display, and the touch panel display functions as the display unit 11 and the input unit 14. Therefore, in the following description, various touch operations on icons on the screen displayed on the display unit 11 are expressed as “tap”, “swipe”, “drag”, and the like. However, the input unit 14 is not limited to a touch panel display, and may be a keyboard, a pointing device, a mechanical switch, or the like.

  Storage unit 15 is configured by an electrically rewritable nonvolatile semiconductor memory such as a flash memory.

(2.2) Measurement system Next, the structure of the measurement system 20 of this embodiment is demonstrated.

  As shown in FIG. 1, the measurement system 20 includes a measurement unit 21, a communication adapter 22, a controller 23, and current sensors 24 and 25. Among these, the measurement unit 21, the communication adapter 22, and the current sensors 24 and 25 are disposed in the cabinet of the distribution board 6. The distribution board 6 includes a main breaker 61 electrically connected to the system power supply 9 and a plurality of branch breakers 62 electrically connected to the secondary side of the main breaker 61 in the cabinet.

  The measurement unit 21 is electrically connected to the current sensors 24 and 25. The current sensor 24 is provided on the primary side of the main breaker 61 and measures the value of the current flowing through the main line. The current sensor 25 is provided corresponding to the plurality of branch breakers 62 and measures the value of the current flowing through the plurality of branch circuits. Here, the “branch circuit” means each circuit branched from the main line by a plurality of branch breakers 62. The “branch circuit” includes wiring connected to the branch breaker 62, devices such as lighting equipment and cooking appliances, outlets, wall switches, and the like. Such a branch circuit is used in a customer facility 5 made of a house as in the present embodiment, for example, in a living room, bedroom, entrance, toilet, child room, kitchen, etc. It is provided for each type of equipment such as air conditioner.

  The measurement unit 21 measures at least one of the power consumption and the power consumption amount for each of the trunk line and the plurality of branch circuits using the outputs of the current sensors 24 and 25. The communication adapter 22 transmits the measurement value measured by the measurement unit 21 to the controller 23 as the measurement value of the measurement system 20. The controller 23 is connected to the network 4 via the router 7. Note that the power consumption and power consumption of the trunk line correspond to the total power consumption and the total power consumption of the customer facility 5 as a whole.

  In short, the measurement value of the measurement system 20 includes at least one of the power consumption and the power consumption measured by the measurement unit 21 for each of the plurality of branch circuits in the customer facility 5. That is, the measured value may be power consumption representing instantaneous power, or may be power consumption representing power consumption (usage) for a certain period of time. Further, the measured value may be both power consumption and power consumption. In the present embodiment, as an example, the measured value is a power consumption amount obtained by integrating the power consumption for a certain time (for example, 1 minute).

(2.3) Determination System Next, the configuration of the determination system 30 of the present embodiment will be described.

  As shown in FIG. 1, the determination system 30 includes a server device 3 in the present embodiment. The server device 3 is connected to the information terminal device 1 via the network 4.

  The server device 3 determines whether or not the power consumption in the specific circuit is equal to or greater than a threshold according to a predetermined algorithm. Here, at least one branch circuit among the plurality of branch circuits in the customer facility 5 is registered in the determination system 30 as a specific circuit.

  If the power consumption in the specific circuit is equal to or greater than the threshold, the server device 3 determines that the power consumption in the specific circuit is “present”. On the other hand, if the power consumption in the specific circuit is less than the threshold, the server device 3 determines that the power consumption in the specific circuit is “none”. As a result, the server device 3 ignores the standby power of the device, and “exists” power consumption in a specific circuit including the device only when the device is actually operating (used). Can be determined. In the server device 3, whether or not the power consumption in the specific circuit is determined is determined in units of determination time by determining whether or not the power consumption for each predetermined determination time in the specific circuit is equal to or greater than a threshold value. For example, this determination time (“8:30” to “9:00”) is used for a specific circuit in which the power consumption during the determination time of 30 minutes from “8:30” to “9:00” is equal to or greater than the threshold value. Is determined to be “present”. In this embodiment, as an example, the determination time is 30 minutes. However, the determination time is not limited to this example, and the determination time may be 10 minutes, 1 hour, or the like.

  In the present embodiment, the server device 3 has a function of accumulating the measurement values measured by the measurement system 20 for a certain period (for example, for one month), and based on the accumulated measurement values, It is determined whether the power consumption is equal to or greater than a threshold value.

  Note that the threshold used by the server device 3 for the determination may be individually set for each of the plurality of branch circuits so that the thresholds are different among the plurality of branch circuits. For example, when the threshold value for determining operation or non-operation differs depending on the type of equipment (lighting appliance, cooking appliance, etc.), a different threshold is set depending on the type of equipment included in the branch circuit. The threshold used by the server device 3 for determination may be set by the user of the customer facility 5.

  Further, the server device 3 may have a function of determining the presence or absence of power consumption in the specific circuit based on a resident's operation on the input receiving device 8 connected to the network 4. Here, the input reception device 8 is a smartphone provided with a display unit 81 formed of a touch panel display like the information terminal device 1, and is close to the router 7 in accordance with, for example, Wi-Fi (registered trademark). It has a wireless communication function. As a result, the input receiving device 8 can be connected to the network 4 via the router 7. For example, when a resident uses a washing machine included in the specific circuit, when the resident taps a washing start icon displayed on the display unit 81 of the input reception device 8, the resident receives this operation (tap operation), The server device 3 determines that the power consumption in the washing machine is “present”.

  By the way, in this embodiment, the server apparatus 3 has the function to generate | occur | produce the information (unit price information) showing the unit price of the electricity bill applied to the consumer facility 5. FIG. That is, in this embodiment, the unit price information displayed on the display unit 11 of the information terminal device 1 is generated by the server device 3. The unit price information varies depending on the contract (charge menu) between the customer facility 5 and an electric power company such as an electric power company. Therefore, when there are a plurality of customer facilities 5, the server device 3 generates individual unit price information for each customer facility 5. In this case, the server device 3 generates unit price information corresponding to the customer facility 5 based on, for example, customer information input by a user (or customer) of the customer facility 5.

(2.4) Relevance between systems With the configuration described above, the information terminal device 1 of the display system 10 acquires a measurement value from the measurement system 20 via the network 4, and from the determination system 30. The determination result and unit price information can be acquired. However, in the present embodiment, since the server device 3 has a function of accumulating the measurement values for a certain period, the information terminal device 1 does not directly acquire the measurement values from the measurement system 20, but the server device 3 Get from. In other words, the information terminal device 1 acquires the measurement value measured by the measurement system 20 via the server device 3. Here, the server device 3 transmits the measurement value of the measurement system 20 and the determination result as to whether or not the power consumption for the specific circuit is greater than or equal to the threshold value to the information terminal device 1 as usage information. That is, the usage information transmitted from the server device 3 to the information terminal device 1 includes the measurement value of the measurement system 20 and the determination result of the server device 3 (determination result as to whether or not the power consumption amount is greater than or equal to the threshold for the specific circuit). It is information including. As a result, the processing amount in the information terminal device 1 is reduced as compared with the case where the information terminal device 1 separately acquires data (use information and unit price information) from each of the measurement system 20 and the determination system 30.

  About the measured value of the measurement system 20, the information terminal device 1 acquires as time series data at least for every branch circuit. And the information terminal device 1 controls the display part 11 by the display control part 12 using the acquired usage information and unit price information, and displays a desired screen on the display part 11. In this embodiment, as an example, the information terminal device 1 transmits a request (request) to the server device 3 by performing a predetermined operation on the input unit 14, and uses usage information and unit price information as a response to the request. Obtained from the server device 3. However, the trigger for the information terminal device 1 to acquire these data (usage information and unit price information) may be a push notification from the determination system 30, for example.

(3) Detailed description Hereinafter, the control method of the information terminal device 1 which concerns on this embodiment is demonstrated in detail. However, the configuration described below is only an example of the present invention, and the present invention is not limited to the following embodiment, and the technical idea according to the present invention is not deviated from this embodiment. Various changes can be made in accordance with the design or the like as long as they are not.

(3.1) Program The program according to the present embodiment is a program for causing the computer of the information terminal device 1 having the display unit 11 to function as the display control unit 12.

  As shown in FIG. 3, the display control unit 12 displays usage information 101 indicating the usage status of power for a specific circuit including at least one branch circuit among a plurality of branch circuits in the customer facility 5 on the display unit 11. It is displayed on the screen 100. Further, the display control unit 12 displays unit price information 102 representing the unit price of the electricity bill applied to the customer facility 5 on the screen 100 of the display unit 11. Here, the display control unit 12 displays the usage information 101 and the unit price information 102 in time series on the screen 100 of the display unit 11 in association with each time zone.

  In short, the computer of the information terminal device 1 functions as the display control unit 12 by executing the program of the present embodiment, and can display an arbitrary screen on the display unit 11. According to this program, on the screen 100 of the display unit 11, as shown in FIG. 3, for example, usage information 101 and unit price information 102 are displayed in time series in association with each time zone.

  That is, the display unit 11 of the information terminal device 1 includes usage information 101 that indicates the usage status of power for a specific circuit including at least one branch circuit among a plurality of branch circuits, and electricity applied to the customer facility 5. Unit price information 102 representing the unit price of the fee is displayed together. Moreover, the usage information 101 and the unit price information 102 are displayed in time series in association with each time zone. Therefore, the customer can also confirm the unit price of the electricity bill in each time zone when confirming the power usage status in the specific circuit. That is, the customer can check the usage status of the power in the specific circuit from the screen displayed on the display unit 11 in association with the unit price of the electric charge for each time zone. As a result, the customer can make a use plan of the equipment so as to keep the electricity bill low by, for example, so-called time shift that shifts the equipment usage time zone to a time zone where the unit price of the electricity bill is low.

  Therefore, according to the program of this embodiment, there exists an advantage that the display of the usage information 101 showing the usage condition of the electric power in the consumer facility 5 can be utilized more effectively.

(3.2) Screen Configuration Hereinafter, the configuration of the screen 100 of the display unit 11 will be described in more detail.

(3.2.1) Usage Information and Unit Price Information In the present embodiment, the screen 100 is displayed in a vertical orientation so that the longitudinal direction of the display area of the display unit 11 is vertical. That is, the screen 100 is a vertically long screen. The usage information 101 is displayed below the unit price information 102 on the screen 100. In the example of FIG. 3, usage information 101 is displayed in a range of about 5/6 from the bottom in the vertical direction of the screen 100.

  In the example of FIG. 3, the usage information 101 represents the power usage status in the specific circuit with the horizontal direction of the screen 100 as the time axis. Specifically, time information 103 corresponding to the time axis is displayed above the unit price information 102. Here, as an example, the time information 103 is graduated at predetermined time intervals in the time zone from “8:00” to “13:30”. The scale is given in increments of the above-described determination time, and in this embodiment, it is in increments of 30 minutes as an example.

  The time axis in the horizontal direction of the screen 100 is common to the usage information 101 and the unit price information 102. Further, the time in the usage information 101 is not the time when the information terminal device 1 acquires the measurement value, but the time when the measurement value is measured by the measurement system 20.

  Here, the specific circuit includes two or more branch circuits among the plurality of branch circuits. That is, the specific circuit is not only one circuit, but at least two or more circuits. The usage information 101 is information representing the power usage status for each of two or more branch circuits as specific circuits. In this embodiment, a plurality of branch circuits including at least “living room air conditioner”, “western room 1 air conditioner”, “IH heater”, “living room / lighting”, “rice cooker”, “western room 3 air conditioner” are specified. Assume that it is registered as a circuit. In other words, a plurality of specific circuits are set in this embodiment.

  Further, in the example of FIG. 3, at the left end of the usage information 101, circuit names of each specific circuit (“living / air conditioner”, “western room 1 / air conditioner”, “IH heater”, “living / lighting”, “rice cooker” ”,“ Western room 3 / air conditioner ”) is displayed. Further, below the circuit name of each specific circuit, information on the power consumption amount in the target period in the specific circuit is displayed. Here, the information regarding the power consumption is text information obtained by converting the power consumption into an electricity bill. That is, in the example of FIG. 3, the electricity charge for the “living room / air conditioner” period is “201 yen”. In the present embodiment, as an example, the target period is a period from midnight to the current time on that day.

  The display control unit 12 uses, as usage information 101, information indicating the power usage status for each of a specified number of branch circuits from a branch circuit that consumes a large amount of power in the target period among two or more branch circuits as specific circuits. It is displayed on the screen 100. That is, the power usage status is displayed on the screen 100 as the usage information 101 only for a specific number of specific circuits from the side with the largest amount of power consumption in the target period among the plurality of specific circuits. As for the specified number of specific circuits, information indicating the power usage state is displayed in the vertical direction (direction orthogonal to the time axis) as shown in FIG. In the example of FIG. 3, the specific circuits of “living / air conditioner”, “western room 1 / air conditioner”, “IH heater”, “living / lighting”, “rice cooker”, “western room 3 / air conditioner” Information indicating the power usage status is displayed. In this embodiment, as an example, the specified number is “6” (6 circuits).

  Furthermore, in this embodiment, the display control unit 12 arranges information indicating the power usage status for each of the specified number of branch circuits in order from the branch circuit with the largest amount of power consumption in the target period, and displays the screen 100 as the usage information 101. To display. In the example of FIG. 3, the amount of power consumption in the target period is the largest in the branch circuit displayed in the uppermost stage, and is smaller in the lower branch circuit. In other words, in the example of FIG. 3, “living room / air conditioner”, “western room 1 / air conditioner”, “IH heater”, “living / lighting”, “rice cooker”, “western room 3”・ In order of “air conditioner”.

  In the present embodiment, switching buttons 104 and 105 for switching the target period are displayed on the screen 100. The switching buttons 104 and 105 are displayed above the time information 103 on the screen 100. That is, by default, the target period is a period from midnight on the current day to the current time as described above. When the switching button 105 labeled “Yesterday” is tapped in this state, the target period is switched from yesterday's midnight to 24:00. When the target period is switched, the usage information 101 and the unit price information 102 displayed on the screen 100 are switched to information on the target period (here, yesterday). At this time, the specific circuit displayed as the usage information 101 and the arrangement order of the specific circuit may change. Further, when the switching button 104 labeled “today” is tapped, the target period returns to the period from midnight to the current time on that day. Accordingly, the usage information 101 and the unit price information 102 displayed on the screen 100 are switched to information on the target period (here, the current day).

  In the present embodiment, the usage information 101 includes a determination result as to whether or not the power consumption for the specific circuit is greater than or equal to the threshold value. That is, the usage information 101 includes the determination result of the presence / absence of power consumption in the specific circuit determined by the determination system 30. In the usage information 101, for example, as shown in FIG. 3, the display mode of each time zone divided in units of 30 minutes varies depending on whether or not the specific circuit consumes power. The display mode here is, for example, a display color. When the power consumption is “present”, a predetermined color (such as orange) is displayed, and when the power consumption is “none”, (white) is displayed. .

  Thus, in the example of FIG. 3, the usage information 101 is a specific circuit in each of the plurality of bar graphs B1 to B7 that represents the time zone in which the horizontal direction of the screen 100 is the time axis and the power consumption is “present”. It represents the usage status of the power. In other words, each of the plurality of bar graphs B1 to B7 represents a period during which the devices included in the plurality of specific circuits are in the operating state (operating state). For example, the bar graph B1 represents that the devices included in the specific circuit (here, “living / air conditioner”) are in an operating state from “8:30” to “13:00”. Therefore, from the usage information 101, it is possible to grasp the presence / absence of power use and the duration of power use in each time zone.

  Further, the usage information 101 includes information representing an electricity bill for the specific circuit. In the example of FIG. 3, a plurality of rate information F1 to F7 representing an electricity rate is displayed in a one-to-one correspondence with the plurality of bar graphs B1 to B7. That is, each of the plurality of charge information F1 to F7 is text information obtained by converting the power consumption generated by the power consumption in the specific circuit represented by the corresponding bar graphs B1 to B7 into an electric charge. For example, the charge information F2 corresponding to the bar graph B2 indicates that the electricity charge for the power consumption from “9:00” to “13:00” in the specific circuit (here, “Western room 1 / air conditioner”) is “105 yen”. It represents something. Here, as an example, the fee information F1 to F7 is displayed over the corresponding bar graphs B1 to B7.

  The unit price information 102 is displayed above the usage information 101 on the screen 100. In the example of FIG. 3, unit price information 102 is displayed between the time information 103 and the usage information 101 in the vertical direction of the screen 100. The unit price information 102 is text information representing the unit price of the electricity charge in each time zone, and is displayed along the time axis common to the usage information 101 so as to correspond to the usage information 101 for each time zone. Here, it is assumed that the unit price of the electricity charge of “7:00 to 10:00” is “26 yen”, and the unit price of the electricity charge of “10:00 to 17:00” is “32 yen”. Therefore, the unit price information 102 includes text information in which “10:00” is a boundary and the time zone before “10:00” is “26” and the time zone after “10:00” is “32”. .

  Further, in the present embodiment, the display control unit 12 displays the main information indicating the power usage status of the main circuit including the main circuit breaker 61 of the customer facility 5 on the screen 100 together with the usage information 101 and the unit price information 102. Is possible. That is, information representing at least one of power consumption and power consumption of the trunk line can be displayed on the screen 100 as main information. The trunk information is information corresponding to at least one of the total power consumption and the total power consumption in the customer facility 5 as a whole. The main information is displayed in a graph format in which, for example, the horizontal axis is a time axis and the vertical axis is a measured value, unlike the usage information 101 that represents the power usage status in the bar graphs B1 to B7. Alternatively, the main information may be only text information (numerical value) representing a measurement value. The trunk information can be folded (that is, not displayed) by a customer's predetermined operation on the input unit 14 of the information terminal device 1, and FIG. 3 shows a state in which the trunk information is folded.

  By the way, in this embodiment, the display control unit 12 can scroll the usage information 101 and the unit price information 102 displayed on the screen 100 by the customer's slide operation on the input unit 14 of the information terminal device 1. . In the present embodiment, as described above, the touch panel display functions as the display unit 11 and the input unit 14. Therefore, when a swipe operation in the horizontal direction (time axis direction) is performed on the screen 100 in a state where the screen 100 is displayed, the usage information 101 and the unit price information 102 on the screen 100 are changed according to the swipe operation. Scroll in the axial direction, that is, in the horizontal direction. As a result, the usage information 101 and the unit price information 102 displayed on the screen 100 are shifted along the time axis, and the past usage information 101 and the unit price information 102 can be displayed retrospectively. Since the usage information 101 and the unit price information 102 are displayed in association with each time zone, of course, when the usage information 101 scrolls, the unit price information 102 also scrolls in accordance with the usage information 101. The time information 103 is also scrolled together with the usage information 101 and the unit price information 102.

  However, since the usage information 101 and unit price information 102 in the future cannot be displayed as a matter of course, the upper limit (upper end) of the scrollable range is the current time. Note that the usage information 101 and unit price information 102 displayed first when the screen 100 is displayed are the latest usage information 101 and unit price information 102. Note that the slide operation is not limited to a swipe operation, and may be a drag operation on a slider on a scroll bar, for example.

  Further, the usage information 101 may be scrollable in the vertical direction (direction perpendicular to the time axis) by a sliding operation on the input unit 14 of the information terminal device 1. That is, as in the present embodiment, when the number of specific circuits displayed on the screen 100 as the usage information 101 is a specified number (here, “6 circuits”), the specific circuits that exceed the specified number are used. The information 101 cannot be displayed on the screen 100 at a time. Therefore, by enabling vertical scrolling, the usage information 101 can be displayed on the screen 100 even for specific circuits that are not displayed at a time, that is, exceeding a specified number.

  Further, with the customer touching the screen 100 with two fingers, the display mode of the screen 100 can be changed by “pinch in” that reduces the interval between the two fingers or “pinch out” that increases the interval between the two fingers. It may be changed. For example, the pitch in the time axis direction may be narrowed by a pinch-in operation, and the range in the time axis direction of the usage information 101 and unit price information 102 displayed on the screen 100 may be widened. In this case, the pitch in the time axis direction is widened by the pinch-out operation, and the ranges in the time axis direction of the usage information 101 and the unit price information 102 displayed on the screen 100 are narrowed. Also for the time information 103, the range displayed on the screen 100 changes together with the usage information 101 and the unit price information 102.

  Further, the display mode of the screen 100 that is changed by the pinch-in operation and the pinch-out operation is not limited to the display range in the horizontal direction (time axis direction) of the screen 100, and may include the vertical display range of the screen 100. . When the display range in the vertical direction of the screen 100 changes, for example, the usage information 101 changes the number of specific circuits displayed on the screen 100. Here, the direction in which the display range of the screen 100 changes may be limited to only one of the horizontal direction and the vertical direction of the screen 100. That is, both the horizontal and vertical display ranges of the screen 100 may change, only the horizontal display range of the screen 100 may change, or only the vertical display range of the screen 100 may change. It may change. In this case, it is preferable that the customer can set the direction in which the change in the display range of the screen 100 is allowed. Thereby, at the time of pinch-in operation or pinch-out operation, it can avoid that the display range of the screen 100 changes to the direction which a customer does not intend, and operativity improves.

(3.2.2) Breakdown Information In the present embodiment, the display control unit 12 sets the electricity charge for the specific circuit for each unit price of the electricity charge by a predetermined operation of the customer with respect to the input unit 14 of the information terminal device 1. The breakdown information to be displayed is displayed on the screen 100. Hereinafter, the breakdown information 106 will be described with reference to FIG.

  In the present embodiment, each of the plurality of bar graphs B <b> 1 to B <b> 7 in the usage information 101 also serves as an icon for displaying the breakdown information 106. That is, when any one of the plurality of bar graphs B1 to B7 is tapped, detailed information related to the tapped bar graphs B1 to B7 is popped up on the screen 100 as the breakdown information 106. For example, when the bar graph B2 indicating the power usage state of a specific circuit (here, “Western-style room 1 / air conditioner”) is tapped, the breakdown information 106 corresponding to the bar graph B2 is popped up.

  The breakdown information 106 displayed in this way is text information that represents the electricity bill for the specific circuit (here, “Western room 1 / air conditioner”) for each unit price of the electricity bill. Specifically, the breakdown information 106 illustrated in FIG. 4 includes power from “9:00” to “13:00” on October 10 (“10/10”) in “Western-style room 1 / air conditioner”. This shows the breakdown of electricity charges related to consumption. According to the breakdown information 106, in “9:00 to 10:00” where the unit price is “26 yen”, the amount of power used is “600 Wh” and the electricity rate is “15.6 yen”. In addition, in “10:00 to 13:00” where the unit price is “32 yen”, the amount of power used is “2800 Wh” and the electricity bill is “89.6 yen”.

  The breakdown information 106 includes a close button 107 for closing the breakdown information 106. Therefore, when the close button 107 of the breakdown information 106 is tapped, the display of the breakdown information 106 is terminated and the original screen 100 is restored. In FIG. 4, the state in which the screen 100 is switched is schematically represented by arrows.
