[First Embodiment]
Hereinafter, an example of the first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing an example of an energy consumption display system according to an embodiment of the present invention.

  In the present embodiment, the power from the grid power 12 is supplied to the distribution board 14 of the house 10 via the main breaker 100.

  On the system power side of the main breaker 100, a main breaker current sensor 110 that detects the current value of the power supplied from the system power 12 is provided. The power supplied from the grid power 12 to the distribution board 14 is distributed to the power load means provided in the living room 56 and the kitchen 58 and the electric lock 52 provided in the door 66 via the branch circuits 20A to 20E. .

  In the present embodiment, as an example, branch circuits 20A and 20B are led to living room 56, branch circuit 20A is connected to air conditioner 18, and branch circuit 20B is connected to lighting 26. The branch circuits 20C and 20D are led to the kitchen 58, the branch circuit 20C is connected to the microwave oven 32, and the branch circuit 20D is connected to the illumination 28. The branch circuit 20E is connected to the electric lock 52.

  The branch circuits 20A to 20E are provided with current sensors 22A to 22E for measuring the current values of the branch circuits 20A to 20E, respectively. The information lines from the current sensors 22 </ b> A to 22 </ b> E are information for controlling the distribution board 14 by the information line from the main breaker current sensor 110 and the HEMS (Home Energy Management System) 30 that manages and controls the energy in the house. It is connected to the HEMS 30 together with the line. In FIG. 1, the broken line is an information line through which measurement data or control information flows. The current values detected by the current sensors 22A to 22E are associated when the current values are detected, and are stored in the memory of the HEMS 30 as detection results of the current sensors 22A to 22E.

  The branch circuits 20A to 20E of the distribution board 14 are respectively provided with branch breakers 24A to 24E for switching the branch circuits 20A to 20E to an on state or an off state, and the branch breakers 24A to 24E are controlled by the HEMS 30. .

  In FIG. 1, for simplicity of description, only five branch circuits are shown, but in this embodiment, the number of branch circuits may be five or more and five or less, and the number of branch circuits is not particularly limited. .

  An electric lock 52 is connected to the HEMS 30. The HEMS 30 determines whether or not the authentication information input to the electric lock 52 with a card key or the like is appropriate, and locks or unlocks the electric lock 52 if the determination is affirmative. Also, human sensors 34A and 34B are connected to the HEMS 30. The human sensor is a sensor that detects the presence or absence of a person using infrared rays or ultrasonic waves. In the present embodiment, a human sensor using infrared rays is used as an example. As described later, the HEMS 30 can also grasp the trends of residents in the house based on the results detected by the human sensors 34A and 34B.

  The HEMS 30 is connected to a termination device 54 that is a gateway, and is connected to the network 60 via the termination device 54. An information server 120 for the grid power 12 is connected to the network 60, and the HEMS 30 can appropriately acquire information related to the electricity bill from the information server 120.

  FIG. 2 is a block diagram showing a schematic configuration of the HEMS 30 according to the energy consumption display system according to the present embodiment.

  As shown in FIG. 2, the HEMS 30 includes a CPU 36, a ROM 38, a RAM 40, and an input / output port 42. These include a bus 44 such as an address bus, a data bus, and a control bus. Are connected to each other.

  A display unit 46, an operation unit 48, and a memory 50 are connected to the input / output port 42 as various input / output devices. The display unit 46 and the operation unit 48 are integrally configured, and a touch panel provided on the display unit 46 can be applied to the operation unit 48.

  The display unit 46 can display a time-series change in the power consumption amount on the designated date of the house 10. In addition, the display unit 46 includes power consumption in each area which is a plurality of areas in the house 10 such as a living room and a kitchen, power consumption in each of the branch circuits 20A to 20E, and a specific time zone. The details of the power consumption can be displayed. In addition, the display unit 46 can also display information such as the unit price of charges by hourly electric lights and the trend of residents. The operation unit 48 is, for example, an “outing mode” that is energy management for energy saving that stops power supply to lighting and the like that are unnecessary when a resident of the house 10 goes out and goes out and the house 10 becomes unattended. Can be turned on or off. When the “outing mode”, which means that the resident has gone out, is turned on, the HEMS 30 is connected to a device that does not require power supply when going out, such as lighting, by turning off the branch breaker, etc. Stop supplying power to the branch circuit.

  The memory 50 includes a program for controlling the branch breakers 24A to 24E, a program for calculating power consumption in the house 10 based on the detection results of the current sensors 22A to 22E, and various information for executing these programs. It is remembered. The HEMS 30 expands a program stored in the memory 50 to the RAM 40 or the like and executes the program by the CPU 36, thereby performing various controls such as control of power supplied to the house 10 and calculation of power consumption.

  The power consumption of the house 10 can be calculated from the current values detected by the current sensors 22A to 22E. Since the voltage supplied from the distribution board 14 is approximately 100 V, in this embodiment, the current value detected by each current sensor is multiplied by 100 to calculate the power consumption. However, in a branch circuit with a large voltage fluctuation, a means for measuring the voltage may be provided separately. The detection results of the current sensors 22A to 22E and the data of the power consumption based on the detection results are accumulated in the memory 50 in association with the date and time when the current sensors 22A to 22E detect the current value. In addition, the memory 50 also stores an on / off history of the “outing mode” and detection results of the human sensors 34A and 34B.

  The input / output port 42 of the HEMS 30 is connected to the distribution board 14, human sensors 34 </ b> A and 34 </ b> B, the electric lock 52, the terminal device 54, and the like.

  Subsequently, control of the HEMS 30 according to the present embodiment will be described. FIG. 3 is a flowchart showing an example of processing for displaying the power consumption amount of the HEMS in the energy consumption display system according to the present embodiment.

  In step 300, it is determined whether the day, month or year for displaying the power consumption amount is specified from the operation unit 48. If the determination is affirmative, the day, month or year specified from the memory 50 in step 302 is determined. The current value records detected by the current sensors 22A to 22E are acquired. In this embodiment, it is assumed that a record of the current value is acquired from the memory by specifying the day.

  In step 304, information on electricity charges such as unit prices of electricity charges is acquired. Since the electricity charge can vary from day to day, in the present embodiment, it is assumed that the latest information can be acquired from the information server 120 of the grid power 12. Details of the acquisition of information on the electricity bill will be described later with reference to the flowchart of FIG.

  In step 306, the power consumption is calculated by calculating the power consumption for each unit time, area, and branch circuit on the specified day, and multiplying it by the unit price of the electricity bill.

  In step 308, an action history, which is a history of trends of residents on a specified day, is calculated. Details of the calculation of the action history will be described later with reference to FIG.

  In step 310, the display unit 46 displays the calculated electricity bill, information on the electricity bill such as the unit price of the hourly lamp, the behavior history of the resident, and the like.

  In step 312, it is determined whether or not a specific time zone has been specified. If the determination is affirmative, an electricity bill based on the power consumption by area and branch circuit in the time zone specified in step 314 is calculated. Then, the electricity cost calculated in step 316 is displayed on the display unit 46, and the process is terminated. If the determination in step 312 is negative, the process ends without calculating the electricity bill based on the power consumption in a specific time zone.

  In FIG. 3, the electricity cost based on the power consumption is displayed in steps 310 and 316. However, in this embodiment, the power consumption (KWh) may be displayed instead of the electricity cost (yen). .

  FIG. 4 is a diagram illustrating an example of a screen display in the energy consumption display system according to the present embodiment. In FIG. 4, a period unit selection button 72 is provided on the upper left side for selecting the unit of the period for displaying the power consumption or the electricity bill by “year”, “month”, and “day”. In the present embodiment, the screen display in the present embodiment will be described in terms of “day” units that are most frequently used.

  There is a date display 74 on the right side from the upper center of FIG. 4, and the displayed date can be changed by touching the date selection button 76. Below the period unit selection button 72, there is a display unit selection button 80 for switching the display between electricity (yen) and power consumption (kWh). Next to the display unit selection button, a graph display selection button for selecting whether to display only the date data displayed in the date display section 74 as a graph or whether to display the previous data as a line graph. There are 82.

  In the present embodiment, the case where the electricity bill (yen) is displayed for the day displayed on the date display unit 74 and the previous day will be described with reference to FIGS.

  The electricity bill in the time series of the day displayed in the date display part 74 is a bar graph for each unit time, and the change in the electricity bill in the time series of the day before the day displayed in the date display part 74 Is a line graph and is displayed on the entire display unit 84.

  Below the overall display section 84 is an action history display section 86 that shows the time zone where the resident is out as a colored portion. Under the action history display section 86, the unit price of the electricity rate changes depending on the time zone. There is an electricity unit price display section 88 that shows the unit price of the electricity charge of the electric lamp according to time zone. The action history display unit 86 and the electricity unit price display unit 88 share the time series scale with the whole display unit 84 and are displayed on the same time axis. Therefore, what is the relationship between the change in the electricity bill displayed in the whole display unit 84 in time series and the resident's going out or staying at home, or what relationship is with the unit price of the electricity bill that changes depending on the time zone? It is designed to help you figure out if there is. Note that at least one of the action history display unit 86 and the electricity unit price display unit 88 may be displayed.

  In the present embodiment, the bar portion of the bar graph in the whole display portion 84, the time zone displayed in the action history display portion 86, and the unit price of the electricity rate for each time zone displayed in the electricity rate unit price display portion 88. Can be selected by touching, and the display color of the selected portion changes.

  For example, when some of the bars of the bar graph are selected on the entire display unit 84, the color of the selected bar changes from a blue-based cold color to a warm color such as orange. As an example, when the resident of the action history display unit 86 touches the time zone when the resident is out, the bar graph of the corresponding time zone on the overall display unit 84 changes from cool color to warm color. Similarly, when the unit price of the electricity charge is arbitrarily selected on the electricity charge unit price display unit 88, the bar graph of the time zone to which the unit price is applied on the overall display unit 84 changes from cool color to warm color.

  On the right side of the whole display section 84, there is provided a detailed display section 90 that can display the electricity bill by area such as a living room, by the branch circuits 20A to 20E of the distribution board 14, or by time zone. In the present embodiment, the area means another living room 56 or kitchen 58 in FIG. In FIG. 1, power is supplied to the living room 56 via the branch circuits 20A and 20B, and the kitchen 58 via the branch circuits 20C and 20D. The electricity bill in the area in the present embodiment is based on the result of consuming the power supplied through the branch circuit connected to the area. In the present embodiment, the correspondence relationship between each area such as a living room and the branch circuit connected to each area is stored in the memory 50.

  In FIG. 4, as an example, the electricity charges for each area are displayed in descending order. In FIG. 4, the electricity bill is high in the living room, but it is possible to take energy saving measures such as encouraging power saving of power load means such as home appliances provided in the area where the electricity bill is high. .

  In addition, the maximum value of the electricity bill for each area is displayed in a certain length over the range that can be displayed on the screen.

  At the upper part of the detailed display section 90, there is a display content switching button 92 for switching the electricity bill to display by area, branch circuit, and time zone, and the time zone display is adjacent to the display content switching button 92. There are a section 94 and a time zone selection button 96. In the present embodiment, by touching the time zone selection button 96, an arbitrary time zone of the day displayed on the year / month / day display unit 74 can be selected, and the selected time zone is displayed on the time zone display unit 94. Then, the electricity bill for each area or branch circuit in the selected time zone is displayed. When a time zone is not selected, the electricity fee for each time zone, the electricity fee for each area, or for each branch circuit on the date displayed on the date display unit 74 is displayed.

  When a time zone is selected with the time zone selection button 96, the bar graph of the corresponding time zone in the left overall display portion 84 changes from cool color to warm color. Similarly, when an arbitrary area is touched on the action history display section 86 or the electricity unit price display section 88, which touches a bar graph of an arbitrary time slot on the entire display section 84, the time slot corresponding to the touched area is displayed in the detail display section. 90 is also selected.

  FIG. 5 is a diagram illustrating an example of a display when “branch” is touched on the display content switching button 92. Unlike FIG. 4, the electricity bills are displayed in descending order for each branch circuit. In this way, by displaying the electricity bill for each branch circuit instead of for each area, it is possible to identify a branch circuit that consumes a large amount of power and a power load means such as a home appliance connected to the branch circuit. It is possible to take energy-saving measures such as encouraging power saving. Note that the maximum electricity cost for each branch circuit is also displayed in a certain length over the entire displayable range on the screen.

  FIG. 6 is a diagram showing an example of display in the default state in the present embodiment when none of the entire display unit 84, action history display unit 86, or electricity unit price display unit 88 is selected. . Electricity charges are displayed for each time zone related to the charge category of the hourly electric lights on the date displayed on the date display unit 74. Any area of the entire display unit 84, the action history display unit 86, or the unit price display unit 88 is selected, and the electricity bill for the selected time zone is displayed on the detailed display unit 90 as shown in FIGS. In this case, the display content switching button 92 can select “area” and “branch”, and cannot select “time zone”.

  Next, the electricity rate information acquisition process in step 304 in FIG. 3 will be described. FIG. 7 is a flowchart showing an example of the electricity bill acquisition process in the energy consumption display system according to the present embodiment. In the present embodiment, the information on the electricity rate such as the unit price is basically obtained by using the information stored in the memory 50. However, since the unit price of charges may change suddenly, it is desirable that the latest information can always be acquired.

  In step 700, the identifier of the information on the electricity bill stored in the memory 50 is confirmed. For example, the identifier may be a time stamp, version information, or the like of information on stored electricity charges.

  In step 702, the information server 120 of the grid power 12 is inquired about the presence / absence of the latest electricity bill information. In step 704, it is determined whether or not there is an update of information on electricity charges. The determination is made, for example, by comparing the identifier of the electricity bill information stored in the memory 50 with the identifier of the electricity bill information uploaded to the information server 120.

  If the determination in step 704 is affirmative, the electricity rate information updated in step 706 is obtained, and the electricity rate information acquisition process is terminated. If the determination in step 704 is negative, the electricity rate information acquisition process is terminated without obtaining the electricity rate information from the information server 120.

  Next, the action history calculation process in step 308 of FIG. 3 will be described. FIG. 8 is a flowchart showing an example of an action history calculation process in the energy consumption display system according to the present embodiment. In the present embodiment, the action history is basically created based on the history in which the “outing mode” is turned on. However, as described below, the detection results of the human sensors 34A and 34B are used together. It is possible to create an action history that more closely matches the actual situation.

  Step 800 acquires the history of “outing mode” on the specified date from memory 50, and in step 802, it is determined whether there is a record in which “outing mode” is turned on in the acquired history. If the determination in step 802 is affirmative, a record in which “outing mode” is turned on is extracted in step 804.

  In step 806, the detection records of the designated dates of the human sensors 34A and 34B are acquired from the memory 50, and the human sensor non-detection time which is the time when the human sensors 34A and 34B did not detect the presence of a person in step 808. It is determined whether or not there is. If the determination in step 808 is affirmative, the human sensor non-detection time is extracted in step 810, and the human sensor non-detection time extracted in step 812 is overlaid on the specified date. The action history is calculated, and the action history calculation process is terminated.

  If the determination in step 808 is negative, the action history calculation process ends with the record of “outing mode” being extracted in step 804 being the action history of the resident.

  If the determination in step 802 is negative, in step 814, the detection records for the designated dates of the human sensors 34A and 34B are acquired from the memory 50, and in step 816, the human sensors 34A and 34B detect the presence of a person. It is determined whether or not there is a human sensor non-detection time which is the time that has not existed. If the determination in step 816 is affirmative, the human sensor non-detection time is extracted in step 810, and the behavior history calculation process is terminated with the extracted human sensor non-detection time as the action history of the specified date.

  If the determination in step 816 is negative, the resident assumes that the designated date has existed for all days in the house 10 and ends the action history calculation process.

  As described above, according to the present embodiment, the transition of the electricity bill in the time series of all days, the resident's going-out status, and the unit price of the electric light according to time zone on one screen based on the time display of the same scale. indicate. Such display makes it possible to contribute to energy saving based on the trend of residents, corresponding to hourly electric lights.

  Furthermore, according to the present embodiment, it is possible to display the electricity rate for each area or branch circuit of the house 10 in the selected time zone. With such a display, it is possible to specify an area or branch circuit to save power in each time zone, and to save energy in the power load means related to the specified area or branch circuit.

[Second Embodiment]
Next, an example of the second embodiment of the present invention will be described in detail with reference to the drawings. FIG. 9 is a schematic diagram showing an example of the energy consumption display system according to the present embodiment. Compared with the first embodiment, the present embodiment can communicate with the information processing server 62 and the information processing server 62 that distribute information processed and processed information, and receives information from the information processing server 62. The difference is that a portable information terminal 64 that can be displayed on a display is provided. In the present embodiment, the HEMS 30 transmits the detection results of the current sensors 22A to 22E to the information processing server 62 via the termination device 54, receives information from the information processing server 62, and displays the information on the display unit 46. This is also different from the first embodiment. However, since the other configuration is the same as that of the first embodiment, detailed description thereof is omitted.

  Note that the portable information terminal 64 has a communication function by wireless communication such as a tablet computer or a smartphone, and can communicate with the information processing server 62 according to a processing request. A display capable of displaying

  FIG. 10 is a flowchart showing an example of processing of the information processing server 62 in the energy consumption display system according to the present embodiment.

  In step 100, it is determined whether the day, month or year for displaying the power consumption amount is designated from the HEMS 30 or the portable information terminal 64. In the case of an affirmative determination, the detection result of the day, month or year designated from the HEMS 30 or the portable information terminal 64 from the data of the detection results of the current sensors 22A to 22E transmitted from the HEMS 30 and stored in step 102. Get a record of In the present embodiment, it is assumed that records relating to the detection results of the current sensors 22A to 22E are acquired from the memory by specifying the day.

  In step 104, information on the electricity charge such as the unit price of the electricity charge is acquired. Since the electricity charge can vary from day to day, in the present embodiment, it is assumed that the latest information can be acquired from the information server 120 of the grid power 12. Since the acquisition of information on the electricity bill is the same as the processing in the flowchart of FIG. 7, detailed description thereof is omitted.

  In step 106, the power consumption is calculated for each unit time, area, and branch circuit on the specified day, and multiplied by the unit price of the electricity charge. It is assumed that the information processing server 62 grasps the correspondence between the area in the house 10 and the branch circuit and stores it in the memory.

  In step 108, an action history, which is a history of the resident's trend on the specified date, is calculated based on the “outing mode” history transmitted from the HEMS 30 and the detection results of the human sensors 34A and 34B. In this behavior history calculation process, the information processing server 62 stores the transmitted “outing mode” history and the detection results of the human sensors 34A and 34B, and the stored “outing mode” history and human sensor 34A. , 34B is different from FIG. 8 in that the action history is calculated based on the detection result of 34B. However, the rest of the processing is the same as the processing of FIG. The behavior history may be calculated by the HEMS 30 as in the first embodiment, and the information processing server 62 may receive the behavior history from the HEMS 30.

  In step 110, the calculated electricity bill, information on the electricity bill such as the unit price of the hourly lamp, the behavior history of the resident, etc. are transmitted to the HEMS 30 or the portable information terminal 64.

  In step 112, it is determined whether or not a specific time zone has been specified. If the determination is affirmative, an electricity bill based on the power consumption for each area and branch circuit in the time zone specified in step 114 is calculated. Then, the electricity bill calculated in step 116 is transmitted to the HEMS 30 or the portable information terminal 64, and the process is terminated. In the case of a negative determination in step 112, the process ends without calculating the electricity bill based on the power consumption amount in a specific time zone.

  In FIG. 10, the electricity bill based on the power consumption is transmitted in steps 110 and 116. However, in this embodiment, the power consumption (KWh) may be transmitted instead of the electricity bill (yen). .

  As described above, according to the present embodiment, it is possible to reduce the load on the HEMS 30 by substituting the information processing server 62 instead of the HEMS 30 for the calculation of the electricity bill and the result calculated by the information processing server 62. It can be transmitted and displayed not only on the HEMS 30 but also on the portable information terminal 64 via the network 60. In the case where display is possible on the portable information terminal 64, the HEMS 30 may not include the display unit 46 as long as it has a function of collecting data in the house and transmitting data to the information processing server 62.
