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. In the present embodiment, a plurality of devices such as air conditioners (air conditioners) and washing machines included in the plurality of branch circuits are registered as the target device 50.

  The measurement unit 21 measures at least one of power consumption and power consumption as resource consumption data 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 consumption data measured by the measurement unit 21 to the controller 23. 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 consumption data measured by 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 consumption data may be power consumption that represents instantaneous power, or may be power consumption that represents power consumption (usage) for a certain period of time. Further, the consumption data may be both power consumption and power consumption. In the present embodiment, as an example, the consumption data is a power consumption amount obtained by integrating the power consumption for a certain time (for example, one 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 the operation status of the target device 50 according to a predetermined algorithm. There are various items as the operation status of the target device 50 that can be determined by the server device 3. In the present embodiment, as the operation status of the target device 50 determined by the server device 3, whether or not the target device 50 is operating (running), the start and end of the operation of the target device 50, the continuous operation time of the target device 50, and the like. There is.

  However, since it is not necessary to notify all the operation statuses of the target device 50, the server device 3 is configured to determine only a specific operation status that needs to be notified among the operation statuses of the target device 50. In other words, the server device 3 determines the operation status of the target device 50 including the necessity of notification. For example, the server device 3 determines that a specific operation situation has occurred when the target device 50 is not simply started to operate but when the continuous operation time of the target device 50 has reached a set time or more. The “continuous operation time of the target device 50” here means a time during which the target device 50 operates continuously. However, not only the time during which the operation is completely continuous, but also the time during which the operation is temporarily stopped for the target device 50 such as an air conditioner performing intermittent operation, for example. May be included.

  In the present embodiment, at least one branch circuit among the plurality of branch circuits in the customer facility 5 is used as a determination circuit, and the server apparatus 3 changes the consumption data with respect to the determination circuit with time (change with time). ). Here, the server device 3 has a function of accumulating consumption data measured by the measurement system 20 for a certain period (for example, for one month), and the operation status of the target device 50 is determined based on the accumulated consumption data. judge.

  For example, if the power consumption of a determination circuit including a plurality of branch circuits including a certain target device 50 is greater than or equal to a predetermined threshold, the server device 3 determines that the target device 50 is operating (operating). . On the other hand, if the power consumption of a determination circuit including a plurality of branch circuits including a certain target device 50 is less than a predetermined threshold, the server device 3 determines that the target device 50 is stopped. In addition, regarding a determination circuit including a plurality of branch circuits including a certain target device 50, when the power consumption increases from approximately zero to a predetermined threshold or more, the server device 3 indicates that the target device 50 has started operating. judge. On the other hand, when the power consumption of a determination circuit including a plurality of branch circuits including a certain target device 50 is reduced from a predetermined threshold value or more to substantially zero, the server device 3 determines that the target device 50 has finished operating. judge. By comprehensively using these determination results, the server device 3 can determine, for example, the continuous operation time of the target device 50.

  In addition, the server device 3 may have a function of determining the operation status of the target device 50 based on information acquired from the target device 50 by the controller 23 through communication with the target device 50, for example. For example, regarding the air conditioner as the target device 50, the controller 23 acquires information on whether or not it is operating (driving), and the operation status such as the set temperature, and the server device 3 acquires this information via the network 4. Determine the operating status of the air conditioner.

  In addition, the server device 3 may have a function of determining the operation status of the target device 50 based on a resident's operation on the input reception 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 as the target device 50, when the resident taps a washing start icon displayed on the display unit 81 of the input reception device 8, the server device receives the operation (tap operation). 3 determines that the washing machine has started operation (driving).

  By the way, the server device 3 has a function of generating status information based on the determination result (the operation state of the target device 50) obtained as described above. That is, in this embodiment, the status information displayed on the display unit 11 of the information terminal device 1 is generated by the server device 3. Here, the server device 3 generates a message to be notified to the customer as status information based on the operation status of the target device 50. The status information is standardized over various patterns, and is registered in the server device 3. The server device 3 generates status information by selecting a status information pattern from the determination result of the operation status of the target device 50 according to a predetermined algorithm and substituting time, time, and the like into variables.

  Furthermore, in the present embodiment, the status information is classified into one of a plurality of types. In the present embodiment, four types of status information are exemplified: “energy saving”, “housework”, “house and electricity”, and “family”. Status information classified as “energy saving” is status information closely related to the suppression of resource consumption. The status information classified as “housework” is status information closely related to the housework (cooking, washing, cleaning, etc.) of the resident (user of the customer facility 5). The status information classified as “house and electricity” is status information closely related to the current state of the target device 50. The status information classified as “family” is status information closely related to the resident (user of the customer facility 5).

  As specific examples of status information, four items of “energy-saving one-point advice”, “household support”, “keep leaving notification”, and “weather information” are illustrated.

  The status information of “energy saving one-point advice” is classified as “energy saving”, and is, for example, a result of comparing the operation status of the same target device 50 in the first period and the second period. As an example of “energy-saving one-point advice”, there is a result of comparing the electricity consumption (power consumption) of the target device 50 made of an air conditioner between last week and last week. The status information of “energy saving one-point advice” includes a result of comparing the total power consumption in the entire customer facility 5 between the first period and the second period (for example, last week and last week). The status information of “housework support” is classified as “housework” and is, for example, notification of at least one of the start and end of the operation of the target device 50 related to the housework of the resident. As an example of “housework support”, there is a notification of the end of the operation of the target device 50 made of a washing machine.

  The status information of “keep notification” is classified as “house and electricity”, and is, for example, a notification that the continuous operation time of the target device 50 is longer than the set time. As an example of the “keep-notifying notification”, there is a notification that the continuous operation time of the target device 50 made of an air conditioner is longer than the set time, that is, forgetting to turn off the target device 50. The status information of “weather information” is classified as “family” and is, for example, a notification that the temperature is less than a specified value. As an example of “weather information”, there is a notification that the weather condition is likely to catch a cold. The “weather information” as the status information is information based on, for example, the operating state (measurement value) of the temperature sensor as the target device 50.

(2.4) Relevance between systems With the configuration described above, the information terminal device 1 of the display system 10 acquires consumption data from the measurement system 20 via the network 4, and from the determination system 30. It is possible to obtain status information. However, in this embodiment, since the server device 3 has a function of accumulating consumption data for a certain period, the information terminal device 1 does not directly acquire the consumption data from the measurement system 20, but the server device 3 Get from. In other words, the information terminal device 1 acquires consumption data measured by the measurement system 20 via the server device 3. 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 (consumption data, status information) from each of the measurement system 20 and the determination system 30.

  The information terminal device 1 causes the display control unit 12 to control the display unit 11 to display a desired screen on the display unit 11 using the acquired consumption data and status information. In this embodiment, as an example, the information terminal device 1 acquires status information upon receiving a push notification from the determination system 30, and acquires consumption data by performing a predetermined operation in a state where the status information is received. . However, the trigger for the information terminal device 1 to acquire these data (consumption data, status information) may be, for example, a push notification from the determination system 30 or a predetermined operation on the input unit 14 of the information terminal device 1. It may be. The push notification from the determination system 30 is preferably switchable between on (valid) and off (invalid) in the information terminal device 1.

(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 sets a first region 101 and a second region 102 on the screen 100 of the display unit 11. The display control unit 12 displays consumption information based on consumption data of resources (here, power) in the customer facility 5 in the first area 101. In the second area 102, status information 111 to 114 based on the operation status of the target device 50 in the customer facility 5 is displayed in time series. Hereinafter, when each of the plurality of status information 111 to 114 is not distinguished, it is simply referred to as “status information 110”.

  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, for example, as shown in FIG. 3, a first area 101 where consumption information is displayed and a second area where status information 110 is displayed in time series. 102 is set.

  That is, on the display unit 11 of the information terminal device 1, consumption information based on resource consumption data in the customer facility 5 and status information 110 based on the operation status of the target device 50 in the customer facility 5 are displayed together. Is done. Thereby, the customer (owner of the information terminal device 1) visually sees two pieces of information (consumption information and status information 110) related to the customer facility 5 by looking at the screen 100 displayed on the display unit 11. Can be confirmed. Moreover, the status information 110 is displayed on the display unit 11 in time series. Therefore, the customer can know how the target device 50 is used from the status information 110 displayed in chronological order, including the concept of time, from when to when. Further, by comparing the status information 110 with the consumption information displayed together, the customer can know information such as how the resource is consumed when the target device 50 is used. it can. That is, the customer can find a causal relationship between how the target device 50 is used and the consumption of resources in the customer facility 5 from the screen displayed on the display unit 11. As a result, the customer can make a use plan of the target device 50 so as to suppress the consumption of resources.

  Therefore, according to the program of this embodiment, there exists an advantage that the display of the consumption information based on the consumption data of the resource 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) Consumption 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 first area 101 where consumption information is displayed is set above the second area 102 on the screen 100. In the example of FIG. 3, the left half of the range of about ¼ from the top in the vertical direction of the screen 100 is the first region 101.

  The consumption information is a cumulative value of consumption data in a predetermined measurement period. In the present embodiment, as an example, the measurement period is a period from midnight on the current day to the current time. The consumption data is, for example, the power consumption of the main line, that is, the total power consumption of the customer facility 5 as a whole. However, in the customer facility 5 where the private power generation facility such as the solar power generation facility is installed, the total power consumption in the customer facility 5 as a whole is the power consumption amount of the main line and the power generation amount of the private power generation facility. The sum of Therefore, in the customer facility 5 where the private power generation facility is installed, the consumption data may be only the power consumption amount of the main line, or the sum of the power consumption amount of the main line and the power generation amount of the private power generation facility. May be.

  The consumption information is displayed in the first area 101 of the screen 100 in the form as shown in FIG. In the example of FIG. 3, the consumption information is a numerical value indicating the amount of power consumption (“6.0 kWh” in the example of FIG. 3). Furthermore, in the example of FIG. 3, the consumption information includes a form of an electricity bill that is a product of the amount of power consumption and the unit price of electricity bill. Accordingly, in the first area 101, as “electricity used today”, the accumulated power consumption amount of the customer facility 5 on the current day and the electricity charge of the customer facility 5 on the current day are displayed as consumption information.

  By the way, in this embodiment, the display control part 12 changes the display mode of the consumption information in the 1st area | region 101 with the magnitude | size of the consumption of the resource which consumption data represents. Therefore, the display mode of the consumption information in the first area 101 is not fixed, and changes according to the amount of consumption of resources (here, power) in the customer facility 5. The display mode here is, for example, the background color of consumption information in the first area 101. Specifically, the background color changes from a cold color (for example, light blue) to a warm color (for example, red) as the power consumption included in the consumption information increases. Note that the display mode is not limited to the background color, and may be, for example, the size or shape of a figure serving as the background of consumption information.

  Further, the display control unit 12 may change the display mode of the consumption information in the first area 101 according to the comparison result with the past data of the consumption amount of the resource represented by the consumption data.
