  The program according to the present embodiment is a program for causing the computer of the controller 1 to function as the acquisition unit 12 and the display control unit 13.

  The acquisition unit 12 controls the first communication unit 14 to communicate with the communication adapter 22, thereby measuring consumption data measured by the measurement unit 21 (measured every 30 minutes for each of the trunk line and the plurality of branch circuits 70). Power consumption data). The acquisition unit 12 acquires consumption data from the measurement system 20 regularly or irregularly.

  The acquisition unit 12 accumulates the consumption data acquired from the measurement unit 21 in the storage unit 16. The storage unit 16 has a storage capacity capable of storing power consumption data measured every 30 minutes for each of the trunk line and the plurality of branch circuits 70 for at least the past year.

  The display control unit 13 creates screen data to be displayed on the information terminal device 8 </ b> A based on the power consumption data stored in the storage unit 16. The measurement system 20 measures the power consumption of the main line and the plurality of branch circuits 70 in units of 30 minutes, and the storage unit 16 stores the power consumption data of the main line and the plurality of branch circuits 70 in units of 30 minutes for one year. Assume that more than a minute is accumulated.

  When the user (customer) of the customer facility 5 enters into an actual power supply and demand contract with the power company, the contract power is determined based on the largest value of the maximum demand power for each month in the past year including the current month. The basic charge is determined according to the contract power. Here, the maximum demand power in each month is the largest power consumption in that month among the power consumptions every 30 minutes. In the following, the 30 minutes in which the power consumption is maximized in each month is referred to as a monthly maximum period.

  If the information terminal device 8A displays an annual display screen that displays the maximum demand power for each month in the past year, the customer reviews the supply-demand contract and reviews the power usage status by viewing this screen. be able to. In the display system of the present embodiment, the display control unit 13 creates an annual display screen indicating the maximum value (maximum demand power of each month) of the power purchase amount (power consumption amount) in units of 30 minutes of each month, and the information terminal It is displayed on the device 8A. That is, in the display system of this embodiment, the first period is set to one year, the second period is set to January, and the third period is set to 30 minutes, which is a unit time for measuring power consumption. Accordingly, the first period (one year) includes a plurality of second periods (January), and each of the plurality of second periods (months) includes a plurality of third periods (30 minutes). Become.

  The display control unit 13 obtains the maximum value (maximum demand power) of power consumption for 30 minutes in each month based on the power consumption data acquired by the acquisition unit 12 and is based on the maximum demand power. Seeking power information. For example, the display control unit 13 calculates the average power consumption every 30 minutes by doubling the maximum demand power for each month and changing the unit from [kWh] to [kW]. We ask for information monthly. The display control unit 13 obtains and displays the average power used every 30 minutes as power information, that is, the 30-minute instantaneous value [kW] of power consumption for each month. The maximum value [kWh] of the electric energy may be obtained and displayed every month.

  FIG. 4 shows an example of an annual display screen created by the display control unit 13. In the screen of FIG. 4, the reference numerals and the alternate long and short dash line surrounding the region are only described for explanation, and are not displayed on the actual screen. The same applies to the screens of FIGS. 6, 7A, and 7B.

  The screen 100 of FIG. 4 is a screen showing monthly power information (average power consumption obtained from the maximum value of power consumption for 30 minutes) for the past year. The screen 100 is displayed horizontally so that the longitudinal direction of the display area of the display unit 81 is horizontal. That is, the screen 100 is a horizontally long screen. In the center of the screen 100, an area 101 for displaying a bar graph is provided. The horizontal axis of the bar graph is the month. The vertical axis of the bar graph is power information, that is, the average power used every 30 minutes. In the bar graph, power information (average power consumption) based on the amount of power consumption is displayed in a graph for each month in the past year (in the example of FIG. 4, one year from November 2014 to October 2015). ing. In the following description, 30 minutes in which the amount of power consumption is maximized in each month is referred to as a monthly maximum period, and the bar graph displays power information in the monthly maximum period in each month of one year.

  Here, the display control unit 13 may display the power information of the month having the maximum size (for example, June) among the power information of each month while changing the display mode of the power information of other months. Good. For example, the display control unit 13 changes a display mode such as a color and a pattern between a bar indicating power information of a month (for example, June) with the maximum power consumption and a bar indicating power information of another month. Therefore, the power information of the month (for example, June) with the maximum power consumption can be made conspicuous.

  In the screen 100, an area 102 for displaying the current date and time is provided at the upper right of the bar graph area 101. On the lower side of the bar graph area 101 on the screen 100, a button 103 for selecting a desired month from the past year and a button 104 for displaying a breakdown of power consumption in the selected month are arranged. Has been.

  When the display control unit 13 generates the screen 100 of FIG. 4, the display control unit 13 transmits the data of the generated screen 100 from the second communication unit 15 to the information terminal device 8 </ b> A via the router 7. When the data of the screen 100 transmitted from the controller 1 is received by the communication unit 83 of the information terminal device 8A, the processing unit 82 controls the display unit 81 based on the data of the screen 100 and the display unit 81 The screen 100 is displayed.

  A resident who has seen the screen 100 displayed on the information terminal device 8A can grasp the power information in the monthly maximum period in each month in the past year based on the bar graph displayed in the area 101 of the screen 100. it can.

  Here, the display control unit 13 may display a boundary line 105 indicating a threshold value to be compared with power information (average power usage) on a bar graph displayed in the area 101 of the screen 100. For example, when the maximum demand power is divided into a plurality of categories according to the amount of power, and the basic charge of the electricity rate is determined for each category, the boundary value of each category may be set as the “threshold value”. When the maximum value of the average power consumption exceeds the threshold value, the basic charge increases. Therefore, the resident who looks at the bar graph in the area 101 can grasp the difference between the boundary line 105 indicating the threshold value and the maximum value of the average power consumption. For example, if the maximum value of average power consumption exceeds the boundary 105, the resident can grasp how much the average power consumption can be reduced to reduce the basic charge, and the occupant will try to save power. .

  Further, when the user of the information terminal device 8A taps the button 103 while the screen 100 of FIG. 4 is displayed on the display unit 81 of the information terminal device 8A, the processing unit 82 is a tap input from the input unit 84. A selection screen for selecting the month is displayed on the display unit 81 based on the operation information.

  FIG. 5 is an example of a selection screen 110 for selecting a month. On the selection screen 110, 12 buttons 111 for selecting each month of one year and a button 112 for performing a cancel operation are arranged. The twelve buttons 111 for selecting the month are arranged in four rows, and three are arranged in each row. The button 112 for performing the cancel operation is arranged below the twelve buttons 111 and below the selection screen 110.

  When the user of the information terminal device 8A taps the button 111 of any month while the screen 110 of FIG. 5 is displayed on the display unit 81 of the information terminal device 8A, the processing unit 82 displays the figure on the display unit 81. 4 screen 100 is displayed again. At this time, the processing unit 82 causes the button 103 to display characters indicating the selected month on the screen 100 displayed on the display unit 81.

  Thereafter, when the user of the information terminal device 8A taps the button 104 while the screen 100 of FIG. 4 is displayed on the display unit 81 of the information terminal device 8A, information on the tap operation is input from the input unit 84 to the processing unit 82. Is output. At this time, the processing unit 82 causes the controller 1 to transmit a request signal for requesting the display of the breakdown screen based on the tap operation information. The breakdown screen is a screen that displays branch power information (for example, average power consumption) based on the power consumption in the plurality of branch circuits 70 in the maximum monthly period of the selected month, and shows the power consumption in the maximum monthly period. This is a screen that displays the breakdown.

  When the second communication unit 15 of the controller 1 receives the request signal transmitted from the information terminal device 8A, the display control unit 13 receives the request signal, and the power consumption of each branch circuit 70 in the monthly maximum period of the selected month. The amount of data is read from the storage unit 16. Then, the display control unit 13 creates the breakdown screen data indicating the branch power information (for example, the average power used for each branch circuit 70) based on the power consumption of each branch circuit 70 in the monthly maximum period. The screen data is transmitted from the second communication unit 15 to the information terminal device 8A. In the information terminal device 8A, when the communication unit 83 receives the breakdown screen data, the processing unit 82 causes the display unit 81 to display the breakdown screen.
