  FIG. 3 is a functional block diagram illustrating a schematic configuration of the management apparatus 12 according to the present embodiment. The management device 12 is, for example, a HEMS, and includes a receiving unit 23 and a control unit 24.

  The receiving unit 23 is, for example, an interface, and transmits and receives control signals and various information from the control unit 24 to and from the display device 11, the smart meter 13, the power conditioner 14, and the load device 18.

  For example, the receiving unit 23 can acquire power for purchasing power and / or power for selling from the commercial power supply 50 from the smart meter 13. Further, the receiving unit 23 can acquire demand response (DR) information from, for example, an electric power company or the like via the smart meter 13. In addition, the receiving unit 23 receives power supplied from the power conditioner 14 to the load device 18 through the solar power generation system 15, the power storage unit 16, and a branch branched from the commercial power supply 50 by the distribution board 17. Can be obtained through sensors provided in each branch. In addition, the receiving unit 23 can directly acquire the amount of power (that is, charging power) charged in the power storage unit 16 from the power conditioner 14. The receiving unit 23 can also directly acquire power consumption from each load device 18. In addition, the receiving unit 23 can acquire various information from the network 70.

  Further, the receiving unit 23 can acquire a control signal from the display device 11, and the receiving unit 23 notifies the display device 11 of information indicating the state of power control and management in the power control system 10.

  The control unit 24 generates a control signal for controlling the power of each device in the power control system 10 and / or information to be notified to the display device 11 based on various information acquired by the reception unit 23. In addition, the control unit 24 accumulates information acquired by the reception unit 23 in order to manage the power of each device in the power control system 10.

  The control unit 24 has a database 25 in order to accumulate various collected information. The database 25 can be configured by an arbitrary memory device or the like, and may be connected to the outside of the management device 12 or may be built in the management device 12.

  The control unit 24 accumulates the instantaneous power value acquired by the receiving unit 23 in the database 25 as the instantaneous value. Further, the control unit 24 calculates an integrated value of electric power based on the instantaneous value. The control unit 24 accumulates the calculated integrated value in the database 25 separately from the instantaneous value.

  Next, a specific example of a graph image created by the control unit 24 of the management apparatus 12 according to the present embodiment will be described.

  As an example, the control unit 24 creates a graph image showing a history of the amount of power supplied from the commercial power supply 50 as shown in FIG. The control unit 24 notifies the display device 11 of the created graph image and causes the display unit 19 to display the graph image.

  The horizontal axis of the graph image created by the control unit 24 is an axis indicating time. The horizontal axis shown in FIG. 4 indicates the time range for one day on January 1, 2012. When the input detection unit 20 of the display device 11 detects an operation of changing the time range by the user, the control unit 24 receives the information (detailed power consumption data for each hour or minute on the day) via the reception unit 23. Acquire and create a graph image with the horizontal axis time range changed.

  The input detection unit 20 of the display device 11 can detect two kinds of operations as an instruction to change the time range of the horizontal axis by the user.

  The first operation is an operation of selecting one object from a plurality of objects indicating the time range displayed below the horizontal axis in FIG. In the example illustrated in FIG. 4, the display device 11 displays five objects “hour”, “day”, “week”, “month”, and “year” as objects indicating the time range. When the user selects (touches) one object from the plurality of objects, the input detection unit 20 detects the selection and notifies the control unit 24 of the selection. The control unit 24 acquires the notification via the reception unit 23 and creates a graph in which the horizontal axis is changed to the time range corresponding to the selected object. At this time, the control unit 24 changes the display mode of the selected object. For example, the control unit 24 changes the selected object to an object on which an image of “leaves” is superimposed, such as an object indicating “day” in FIG.

  The second operation is an operation of touching two different locations on the graph image of the display unit 19 and further approaching or separating the two contact positions while touching. Hereinafter, the operation of bringing the two contact positions closer together is also referred to as “pinch-in”, and the operation of separating the two contact positions is also referred to as “pinch-out”.

  In the graph image as shown in FIG. 4, when the input detection unit 20 detects a pinch-in operation, the control unit 21 notifies the control unit 24 of the detection result or a drawing data change request corresponding to the detection result via the interface 22. The control unit 24 acquires the notification via the receiving unit 23 and creates a graph image with a reduced time range. For example, the control unit 24 creates a horizontal axis with a time range of one week, and further changes the display mode of the object indicating “week”. For example, the control unit 24 changes the object indicating “week” to an object on which an image of “leaves” is superimposed.

  Further, in the graph image as shown in FIG. 4, when the input detection unit 20 detects a pinch-out operation, the control unit 21 sends the detection result or a drawing data change request corresponding to the detection result to the control unit 24 via the interface 22. Notice. The control unit 24 acquires the notification via the reception unit 23 and creates a graph image in which the time range is expanded. For example, the control unit 24 creates a horizontal axis with a time range of 1 hour, and further changes the display mode of the object indicating “hour”. For example, the control unit 24 changes an object indicating “time” to an object on which an image of “leaves” is superimposed.

  In the above description, as an example of changing the aspect of the object, from the viewpoint of power saving, an example of superimposing an image designed as a natural object “leaves” is shown, but this is only an example, The method of changing the object mode is not limited to this.

  The vertical axis of the graph image created by the control unit 24 is the instantaneous value or integrated value of power. FIG. 4 shows an example in which the vertical axis represents the transition of the instantaneous value of power. The control unit 24 determines which of the instantaneous value and the integrated value of power is the vertical axis according to the time range on the horizontal axis.

  FIG. 5 shows an example in which the control unit 24 creates a graph image showing the history of the amount of power supplied from the commercial power supply 50 with the vertical axis as the integrated value of power. The control unit 24 has a predetermined threshold value, and when the time range is less than the threshold value, creates a line graph graph image with the vertical axis as the instantaneous power value, and when the time range is equal to or greater than the threshold value, A graph image of a bar graph is created with the axis as the integrated value of power. FIG. 5 shows a case where the control unit 24 creates a graph image with the vertical axis as the integrated value of power when the time range on the horizontal axis is as long as one month. FIG. 4 shows a case where the control unit 24 sets the vertical axis to an instantaneous value of power when the time range on the horizontal axis is as short as one day. Thereby, the control part 24 can produce the graph image which improved visibility according to the time range. The control unit 24 can arbitrarily change the threshold value by setting.

  Next, a process in which the control unit 24 of the management device 12 creates a graph image whose time range has been changed and displays the graph image on the display device 11 will be described with reference to the flowchart shown in FIG.

  The control unit 24 determines whether or not the input detection unit 20 has detected an operation for changing the time range by the user (step S101). When it determines with No in step S101, the control part 24 repeats step S101.

  If it is determined Yes in step S101, the control unit 24 detects whether the operation detected by the input detection unit 20 is (a) a pinch-in / pinch-out operation or (b) an operation for selecting an object indicating a time range. It is determined whether or not there is (step S102).

  If it is determined in step S102 that (a) a pinch-in / pinch-out operation has been detected, the control unit 24 reads data in a time range corresponding to the pinch-in / pinch-out operation from the database 25 (step S103).

  The control unit 24 creates a graph image in which the time range is changed using the data read in step S103. At this time, the control unit 24 changes the display mode of the object indicating the changed time range (step S104).

  The control unit 24 transmits the graph image created in step S104 to the display device 11 and causes the display unit 19 to display the graph image (step S105).

  If it is determined in step S102 that (b) an operation for selecting an object indicating a time range has been detected, the control unit 24 reads data in the time range corresponding to the selected object from the database 25 (step S106). .

  The control unit 24 creates a graph image in which the time range is changed using the data read in step S106. At this time, the control unit 24 changes the display mode of the selected object (step S107).

  The control unit 24 transmits the graph image created in step S107 to the display device 11 and displays it on the display unit 19 (step S108).

  As described above, according to the management device 12 of the first embodiment, the user can flexibly change the time range of the graph image that displays the history of variables regarding energy in the consumer by two operation methods.
