  In this electricity quantity management system, the classification unit compares the model pattern registered in advance in association with each of the groups and the change pattern of the number of people at home of each of the houses, It is desirable to classify into the group corresponding to the model pattern having the most similar change pattern of the number of people at home.

  In this electricity amount management system, the system further comprises a reference calculating unit that calculates, for each group, the amount of electricity used as a reference amount based on the amount of electricity used for the plurality of houses in the same group. More preferably, the unit compares the amount of electricity used in the target house with the reference amount of the group to which the target house belongs.

  In this electricity quantity management system, a special storage unit that stores a period in which the change pattern of the number of people at home is different from a daily period for each individual house as a special period, and the special period stored in the special storage unit are input. And the classification unit classifies the houses into a plurality of groups based on the change pattern of the number of people at home within the monitoring period excluding the special period of each of the houses. Is more desirable.

  In this electricity quantity management system, a special storage unit that stores a period in which the change pattern of the number of people at home is excluded from the group classified by the classification unit for each individual house as a special period, and a special storage unit that stores the period It is more preferable to further include an input unit for inputting the special period to be performed, and a special exception excluding unit for excluding the house in the special period from the group classified by the classification unit.

Further, the center server of the present invention, a measuring device for measuring the electricity consumption for each individual house, the number monitoring unit for monitoring a home number for each individual of the housing is provided for each of the housing, a plurality of the A center server used in an electricity amount management system that compares the electricity usage amount between houses, and collects the number of people at home monitored by the number monitoring device from a plurality of houses as person number information according to time zones A collecting unit, a storage unit for storing the number of people information collected by the collecting unit, and a change pattern of the number of people at home with a lapse of time within a predetermined monitoring period from the number of people information of each house A classifying unit that classifies the houses into a plurality of groups so that the houses with similar change patterns are in the same group; and one of the houses as a target house. The serial electricity consumption, characterized in that it comprises a comparison unit for comparing said electricity consumption of the housing within the group to which the target housing belongs.

  The present invention has an advantage that it is possible to classify houses into appropriate groups in consideration of the life patterns of the householders and to compare the amount of electricity used within each group.

1 is a schematic system configuration diagram showing a configuration of an electricity quantity management system of Embodiment 1. FIG. It is a figure which shows the transition of the number of people used at home used in the same as the above. It is a figure which shows the transition of the electric usage-amount used above. It is a figure which shows the model pattern used in the same as the above. It is a schematic front view which shows the storage box used in the same as the above.

(Embodiment 1)
As shown in FIG. 1, the electricity amount management system 1 of the present embodiment includes a measuring device 2 that measures the amount of electricity used, a number monitoring device 3 that monitors the number of people at home, and a presentation device 4 that presents the amount of electricity used. The storage device 5 and various equipment 6 are provided for each of the plurality of houses 10. In the present embodiment, the presentation device 4 and the storage device 5 are integrated and realized by a home terminal 11 provided in each house 10.

  The measuring device 2, the number monitoring device 3, the home terminal 11, and the equipment 6 provided for each house 10 construct a home network using a general-purpose communication protocol in each house 10. Although only one house 10 is shown in FIG. 1, a similar measuring device 2, person monitoring device 3, home terminal 11 and equipment 6 are provided in other homes (not shown) to construct a home network. The

  Further, the electricity quantity management system 1 includes a center server 8 connected to the Internet 7 as a wide area network. A home network constructed in each house 10 is connected to the Internet 7 via a home gateway 9.

  The measuring device 2 measures the amount of power consumed in each house 10 as the amount of electricity used. Specifically, the measuring device 2 detects a current flowing through a main breaker (not shown), calculates the power (main power) of the entire house 10 supplied through the main breaker, and accumulates the main power. To measure the amount of electricity used. The amount of electricity used is not limited to the amount of power that is an integrated value of the main power, and may be a numerical value obtained by converting the amount of power into an electricity bill, for example.

  The measuring device 2 is configured to measure the amount of electricity used by integrating branch power supplied via a branch breaker (not shown) to a plurality of electric circuits branched from the secondary side of the main breaker. There may be. In this case, the amount of electricity consumed in a specific place such as a living room, for example, instead of the entire house 10 is measured as the amount of electricity used.

  The number monitoring device 3 detects the number of people currently in the house 10 as the number of people at home. Specifically, the person monitoring device 3 has an electric lock (not shown) attached to the entrance door, and the electric lock is unlocked and unlocked using a card key to which an individual identifier is assigned. Thus, the number of people at home is estimated by monitoring the entrance and exit of people into the house 10.

  That is, for example, in the case of a family of five, “Father”, “Mother”, “Sister”, “Brother”, “Brother”, if the electric lock is unlocked using the “Father” card key, the number monitoring device 3 judges that “father” has returned home and increases the number of people at home by one. On the other hand, if the electric lock is locked using the card key of “sister”, the number monitoring device 3 determines that “sister” has gone out and reduces the number of people at home by one.

  In addition, if there is an equipment 6 in which the individual to be used is specified, such as an air conditioner in the study of “Father” or a TV in the room of “Sister”, the number monitoring device 3 will check the usage status of these equipment 6. A configuration may be used in which the home situation of the householder, that is, the number of homes is estimated.

  As will be described in detail later, the presentation device 4 has a function as a Web browser that receives Web content from the center server 8 and displays the Web content. The presentation device 4 may be any device that can display Web content provided from the center server 8, and may be a television, a portable terminal device, a control panel, or a display device dedicated to the electric quantity management system 1, for example. Good.

  The home terminal 11 periodically obtains the number of people at home monitored by the number of people monitoring device 3 and stores the obtained number of people at home in the storage device 5 as number of people information according to time zones. In this embodiment, the home terminal 11 acquires the monitoring result (the number of people at home) from the number monitoring device 3 every hour, and stores the acquired number of people at home in a predetermined monitoring period (here, 1 day). Store in 5. As a result, the number of people information stored in the storage device 5 represents the hourly transition of the number of people at home during the monitoring period (one day) as shown in FIG.

  The number of people at home that the home terminal 11 periodically acquires from the number monitoring device 3 is the number of people who have been at home during most of the period from the previous acquisition time to the current acquisition time. Even if there is a temporary increase / decrease in the number of people at home between the previous acquisition time and the current acquisition time, this temporary increase / decrease is not reflected in the number of homes stored in the storage device 5. For example, even if one out of a family of five people temporarily goes out from 6 to 7 o'clock, such as taking out trash, the number of people at home for most of the period between 6 and 7 o'clock (for example, 40 minutes or more) If there are five, the number of people at home from 6 to 7 o'clock is stored as “5 people”.

  Here, in this embodiment, the number monitoring device 3 counts only the number of householders as the number of people at home, and does not count the number of visitors as the number of people at home. Therefore, for example, in the case of a family of five, the number of people at home changes within a range of five or less as shown in FIG. 2 within the monitoring period, and never exceeds six.

  The home terminal 11 also periodically acquires the amount of electricity used measured by the measuring device 2 and stores the acquired amount of electricity used in the storage device 5 as electricity amount information for each time period. In the present embodiment, the home terminal 11 acquires a measurement result (electric usage) from the measuring device 2 every hour, and stores the acquired electric usage in units of a predetermined monitoring period (here, 1 day). Store in device 5. As a result, the electricity amount information stored in the storage device 5 represents the hourly transition of the electricity usage during the monitoring period (1 day) as shown in FIG.

  The electricity usage amount that the home terminal 11 periodically acquires from the measuring device 2 is a cumulative value of the main power from the previous acquisition time point to the current acquisition time point. For example, if the main power between 5 and 6 o'clock is constant at 500 W, the amount of electricity used at 5 to 6 o'clock is 500 Wh.

  As shown in FIG. 1, the center server 8 includes a classification unit 81 that classifies the homes 10 into a plurality of groups, a comparison unit 82 that compares the amount of electricity used in the group, and a comparison result of the comparison unit 82. A presentation control unit 83 to be presented, and a storage unit 84. The functions of the classification unit 81, the comparison unit 82, and the presentation control unit 83 in the center server 8 are realized by, for example, a computer executing a predetermined program.

  The classification unit 81 obtains a change pattern with the passage of time within the monitoring period (here, 1 day) of the number of people at home from the number of people information stored in the storage devices 5 of the plurality of houses 10, and based on this change pattern A plurality of houses 10 are classified into a plurality of groups. Here, the classification unit 81 uses a plurality of groups prepared in advance to perform grouping so that the houses 10 having similar change patterns become the same group. In the present embodiment, it is assumed that a plurality of groups such as a double-working type, a full-time housewife type, a nighttime working type, and a non-going out type are prepared in advance for each household.

  Specifically, the center server 8 has a collection unit (not shown) that collects information on the number of persons by communication from a plurality of houses 10 having a home network connected to the Internet 7. The number information collected is stored in the storage unit 84. The classification unit 81 groups the plurality of houses 10 whose number information is stored in the storage unit 84 in the following procedure.

  That is, the classification unit 81 first grasps the number of households of each house 10 from the number information. For example, as shown in FIG. 2, for a house with a maximum of five people at home, the classification unit 81 determines that the number of households is five. In order for the classification unit 81 to grasp the number of households, a number storage unit (not shown) that stores the number of households, and a number input unit (not shown) that inputs the number of households stored in the number storage unit May be provided in the home terminal 11 for each house 10. In this case, when the user inputs the number of households in the number input unit in advance, the classification unit 81 can use the numerical value stored in the number storage unit as the number of households.

  Next, the classification unit 81 compares the model pattern registered in advance in association with each group with the change pattern of the number of people at home based on the number of people information acquired from the house 10. In the present embodiment, the change pattern of the number of people at home compared to the model pattern is a pattern in which the change pattern of the number of people at home on weekdays is averaged based on the number of people information for the past week, for example. The model pattern is a change pattern that serves as a model of the number of people at home in the monitoring period (here, one day) for each of the plurality of groups in order to classify the home 10 into a plurality of groups.

  That is, if the number of households in the target house 10 is five, the classification unit 81 includes, for example, four types of groups prepared in advance in association with the number of households “5” as illustrated in FIG. Contrast with model pattern. As a specific comparison method, the classification unit 81 superimposes the change pattern of the number of people at home based on the number of people information acquired from the house 10 and each of the model patterns as shown in FIG. Judgment is based on the difference between the two. That is, the classification unit 81 takes the difference in the number of people at home for each time zone between both patterns (graphs), and determines that the smaller the integrated value of the difference, the more similar.

  For example, the difference from a certain house 10 is “20” in the first model pattern (FIG. 4A), “30” in the second model pattern (FIG. 4B), and the third model pattern ( Assume that “70” in FIG. 4C and “100” in the fourth model pattern (FIG. 4D). In this case, the classification unit 81 determines that the change pattern of the number of people in the house 10 has a minimum difference from the first model pattern shown in FIG. 4A and is similar to the first model pattern. Note that the number of groups prepared in advance is not limited to four and may be any number.

  The classification unit 81 classifies each house 10 into a group corresponding to the model pattern that is determined to have the most similar change pattern of the number of people at home. As a result, the houses 10 having similar change patterns are classified into the same group.

  For example, when the change pattern of the number of people at home in a certain house 10 is similar to the first model pattern as described above, the classification unit 81 determines that the house 10 is a group of the first model pattern (hereinafter referred to as “first group”). "). The classification unit 81 performs the same grouping process as described above for all the houses 10 in which the electricity quantity management system 1 is constructed, thereby classifying all the houses 10 into one of the groups.

  However, the classification unit 81 is configured not to classify any house for which the difference between the change pattern of the number of people at home and the model pattern is larger than a predetermined threshold for any model pattern. There may be. That is, since the house 10 in which the change pattern of the number of people at home is not similar to any model pattern cannot be classified into any group, the classifying unit 81 sets such a house 10 as unclassified.

  Here, the classification unit 81 groups the houses 10 using the number of people information accumulated in the initial setting period (for example, one week) after the start-up of the electricity quantity management system 1, and thereafter periodically (for example, Regroup the group (on a monthly basis). That is, the classification unit 81 groups the homes 10 by comparing the change pattern of the number of people staying at home 10 in the initial setting period with the model pattern, and then periodically changing the number of people staying at home 10 in the model pattern. In contrast, the housing 10 is regrouped. Further, when the housing 10 is newly added to the electricity amount management system 1 or when a request from the user is met, the classification unit 81 performs a predetermined operation on the home terminal 11 or the center server 8 to thereby form a group. The structure which reassembles may be sufficient.

  By the way, in the present embodiment, the center server 8 calculates a reference for calculating, for each group, the amount of electricity used as a reference in the group based on the amount of electricity used by a plurality of houses 10 belonging to the same group. Part 85. The reference amount is the amount of electricity used as a reference when comparing the amount of electricity used within the group, and in this embodiment is the average value of the amount of electricity used by the houses 10 belonging to each group. The storage unit 84 has a function as a reference storage unit that stores the reference amount calculated by the reference calculation unit 85 for each group.

  For example, as shown in Table 1 above, for the first group to which four households, “A's house”, “F's house”, “G's house”, and “K's house” belong, are obtained by the standard calculation unit 85. The reference amount is (8.5 + 10.5 + 12.0 + 8.0) /4=9.75 (kWh / day).

  The comparison unit 82 compares a specific one house among the plurality of houses 10 as the target house, and compares the amount of electricity used in the target house with the reference amount of the group to which the target house belongs. For example, when “A's house” in Table 1 is a target house, the comparison unit 82 compares the amount of power used by “A's house” with the reference amount of the first group. In this case, the comparison unit 82 determines that the electricity usage (8.5 kWh / day) of “A's house” is 1.25 kWh / day less than the reference amount (9.75 kWh / day), and “A's house” Judges that electricity usage is the second lowest among the four households belonging to the first group.

  The presentation control unit 83 causes the presentation device 4 of the target house to present the comparison result of the comparison unit 82. In the present embodiment, the presentation control unit 83 generates a result screen representing the comparison result of the comparison unit 82 as content information (Web content), and provides the content information to the home terminal 11 to display the result screen. To display. For example, when “A's house” in Table 1 is set as the target house, the presentation control unit 83 generates content information representing the comparison result in the comparison unit 82 described above, and this content information is expressed as “A's house”. Provided to the customer's home terminal 11.

  Here, the timing at which the presentation control unit 83 presents the comparison result of the comparison unit 82 to the presentation device 4 may be a system-driven type that is automatically determined or a user-driven type that is manually determined by the user. It may be.

  In the case of the system initiative type, the presentation control unit 83 periodically provides content information to the home terminal 11 at regular intervals (for example, every day). Alternatively, in the case of the system initiative type, the presentation control unit 83 provides content to the home terminal 11 of the house 10 that has a larger amount of electricity usage than the other houses 10 in the group, for example, according to the comparison result of the comparison unit 82. It may be configured to provide information.

  In the case of the system-driven type, the center server 8 also executes the calculation of the reference amount by the reference calculation unit 85 and the comparison by the comparison unit 82 on the basis of the electric quantity information in the fixed period every fixed period (for example, one day). To do.

  On the other hand, in the case of the user-driven type, the home terminal 11 provided in the house 10 receives a user operation and transmits a request signal to the center server 8, and the presentation control unit 83 uses the request signal as a trigger to make a request. The content information is provided to the home terminal 11 that is the signal transmission source. In this case, the center server 8 also uses the request signal as a trigger for the calculation of the reference amount by the reference calculation unit 85 and the comparison by the comparison unit 82. That is, the center server 8 performs the calculation of the reference amount by the reference calculation unit 85 and the comparison by the comparison unit 82 based on the electric quantity information for a certain period (for example, one day) before receiving the request signal.

  Further, in the presentation device 4 of the house 10, as a comparison result of the comparison unit 82, for example, how much (or more) the amount of electricity used in the target house is smaller than (or more than) the reference amount, and The order of the target houses when they are arranged in ascending order of electricity usage is displayed. Alternatively, as the comparison result of the comparison unit 82, the electricity usage amount and the reference amount of the target house may be displayed together. The home terminal 11 may be configured to switch these displays in response to an operation from the user.

  The presentation device 4 may be any device that can present the information (comparison result) provided from the presentation control unit 83 to the householder. For example, the presentation device 4 is a device that presents the comparison result to the householder by voice regardless of the display device. May be.

  According to the electricity amount management system 1 having the configuration described above, the homes 10 having similar patterns of changes in the number of people at home with the passage of time are classified into the same group by the classification unit 81, and the electricity usage of each home 10 is the same group. It is compared with other houses 10 in the comparison unit 82. Since the comparison result of the comparison unit 82 is displayed on the presentation device 4 of each house 10 by the presentation control unit 83, the comparison result of the amount of electricity used with each house 10 belonging to the same group is presented in each house 10. Will be.

  Here, the homes 10 belonging to the same group are homes in which the change pattern of the number of people at home with the passage of time is similar. The change pattern of the number of people at home with the passage of time is closely related to the life pattern of each household, so if the change pattern of the number of people at home is similar, the life pattern tends to be similar. In many cases, there is no significant difference in the number of people at home or the time when the family members return home. Therefore, according to the electricity amount management system 1, the householder (user) of each house 10 can compare the amount of electricity used between his / her own household and other households in consideration of life patterns, and the tendency of the electricity usage of his / her household This makes it easy to obtain an action index for energy saving.

  That is, in the electricity amount management system 1 of the present embodiment, the user can save energy by classifying the homes 10 into appropriate groups in consideration of the life patterns of the householders and comparing the amount of electricity used within each group. Therefore, there is an advantage that an appropriate index can be obtained.

  Further, in the present embodiment, the comparison unit 82 compares the amount of electricity used in the target house with the reference amount calculated by the reference calculation unit 85, so the tendency of the amount of electricity used by a plurality of houses 10 belonging to the same group. Can be notified to the resident of the target house. In other words, the user (household) can know the tendency of the electricity usage of other households whose life patterns are similar to that of their own household by presenting the comparison result between the electricity usage of their own household and the reference amount. It can be used as an index for energy saving.

  By the way, the configuration of the electricity quantity management system 1 is not limited to the configuration described in the above embodiment, but can be appropriately changed as described below.

  For example, the reference amount to be compared in the comparison unit 82 is an average value of the amount of electricity used by the houses 10 belonging to the same group in the above embodiment, but is not limited to this, and the minimum amount of electricity used in the same group. It may be an amount.

  In addition, changes in the number of people at home (number information) and changes in electricity usage (electricity information) are stored in the storage device 5 in units of one day (monitoring period), but the monitoring period is not limited to one day. For example, the number of people information and the amount of electricity information may be stored in units of weeks, months, or years. Furthermore, in the above-described embodiment, changes in the number of people at home and the amount of electricity used are recorded in increments of 1 hour. However, the present invention is not limited to this. For example, changes may be recorded in increments of minutes or hours.

  Further, the method in which the classification unit 81 compares the change pattern of the number of people at home and the model pattern for grouping may be a method using a known statistical pattern classification method. Further, the classification unit 81 uses a statistical pattern classification method without using a pre-registered model pattern, and makes a relative similarity determination among the plurality of homes 10 to be similar. You may classify | categorize so that the houses 10 may become the same group.

  By the way, in the said embodiment, since the electric number lock is unlocked using a card key, the number monitoring apparatus 3 monitors the entrance / exit of the person to the house 10, and estimates the number of people at home, or the individual who uses it. The number of people at home is estimated on the basis of the usage status of the equipment 6 for which is specified. However, in these configurations, the detection accuracy of the number of people at home by the number monitoring device 3 may be lowered.

  For example, when a plurality of householders go out or go home together, when one of them locks / unlocks an electric lock, the number of people at home actually varies for a plurality of persons, An erroneous determination is made that the number of people at home has changed by one person. In addition, when estimating the number of people at home based on the usage status of the equipment 6, if there are cases where the householder is not using the equipment 6 even when he / she is at home, the number of people at home detected by the person monitoring device 3 and the actual home There is an error between the number of people.

  Therefore, the number monitoring device 3 includes a footwear detection unit (not shown) that detects the presence or absence of footwear for going out, and an estimation unit (not shown) that estimates the number of people at home based on the detection result of the footwear detection unit. The structure which has may be sufficient. This configuration has an advantage that the number of people at home detected by the number monitoring device 3 is high.

  As illustrated in FIG. 5, the footwear detection unit is provided in a storage box (clogs box) 31 in which footwear 12 for all the householders is stored, and the storage box depends on whether or not the footwear 12 is taken out from the storage box 31. The presence or absence of footwear 12 in 31 is detected. In the storage box 31, a predetermined space 32 is allocated to each householder. When each householder stores his / her footwear 12 in the storage box 31, the storage box 31 allocates to each space 32 allocated to himself / herself in the storage box 31. Rules are set to store the footwear 12. The footwear detecting unit detects who has lost the footwear 12 by detecting the presence or absence of the footwear 12 for each space 32 allocated to each householder in the storage box 31. For example, in the case of a family of six people, “Father”, “Mother”, “Sister”, “Brother”, “Brother”, and “Grandfather”, if the footwear 12 disappears from the space 32 assigned to “Father” The detection unit detects that the “father” footwear 12 has been lost.

  The footwear detection unit is connected to the home network, and the detection result of the footwear detection unit is notified to the estimation unit connected to the home network. The estimation unit estimates that “Father” has gone out when the “Father” footwear 12 disappears as in the above example. At this time, if all the footwear 12 of the householder other than “Father” is stored in the fixed position of the storage box 31, the estimation unit estimates that the number of people at home is five because the householder other than “Father” is at home. To do. The space 32 allocated to each householder in the storage box 31 is not limited to one foot (a pair of left and right), but may be a plurality of feet. The allocation of the space 32 in the storage box 31 to each householder may be arbitrarily changed along with a change in the family structure.

  Further, the storage box 31 is provided with an invalid switch (not shown), and the person monitoring device 3 may be configured to ignore the entry / exit of the footwear 12 in the storage box 31 while the invalid switch is on. Good. In this configuration, when taking out the footwear 12 from the storage box 31 for purposes other than going out, such as when the householder is washing the footwear 12, the person monitoring device 3 erroneously detects the going-out of the householder by pressing the invalid switch. Can be prevented.

  The number monitoring device 3 may be a device that estimates the number of people at home by cooperating with a schedule system that manages the schedule of going out of each householder, or a device that monitors the number of people at home by other methods. May be.

  In addition, even if the change pattern of the number of people at home is the same, the amount of electricity used may vary greatly depending on the environment (temperature, humidity, sunshine duration, etc.) depending on the area where the house 10 is located. Therefore, it is desirable for the electricity management system 1 to compare the amount of electricity used for the house 10 in the same region (city, ward, etc.).

(Embodiment 2)
The amount of electricity management system 1 of this embodiment, the change pattern of the home number of people in such as a family member of the travel and business trip and quantity of electricity management system 1 of a different period points is also capable of handling configuration according to the first embodiment is the day-to-day Is different.

  In the present embodiment, the storage device 5 of the home terminal 11 has a function as a special storage unit that stores, as a special period, a period in which the change pattern of the number of people at home for each individual home 10 is out of the group classified by the classification unit 81. Have. The special period memorize | stored in the memory | storage device 5 (special example memory | storage part) is input by the householder of each house 10 using the input part (not shown) with which each in-home terminal 11 is equipped for every house 10. FIG.

  Furthermore, in this embodiment, the center server 8 includes a special exception excluding unit (not shown) that excludes the house 10 in the special period from the group classified by the classification unit 81. In other words, the special exception excluding unit excludes, from the group, any home 10 that is in the special period if any one of the plurality of homes 10 classified in a certain group is in the special period. Therefore, the calculation of the reference amount by the reference calculation unit 85 and the comparison by the comparison unit 82 are performed only for the homes 10 that remain after the special case excluding unit 10 excludes the homes 10 during the special period.

  Hereinafter, a specific example of the operation of the electric quantity management system 1 having the above configuration will be described.

In the case where the “A's house” family member is absent in the medium term or long term due to travel or business trip, the “A's house” family member is requested to enter the period and number of persons to be absent at the input section of the home terminal 11. input. For example, in the period from October 1 to October 10, 2009, when two people are absent due to travel, the family member sets the special period to “October 1 to October 10, 2009” and the number of people to “2 people” "Enter the schedule at the input section. Special time and number input in the input unit is stored in the storage device 5 of the home terminal end 1 1. In this case, the special exception excluding unit excludes “A's house” from the group already classified by the classification unit 81 for the special period of “October 1 to October 10, 2009”.

  Moreover, the special exception exclusion unit may be configured not only to exclude the house 10 in the special period from the group but also to regroup the group by the classification unit 81 in consideration of the number of people who are absent. In this case, if two “A's house”, which is a family of five, is absent in the special period, the classification unit 81 assigns “A's house” to the number of households “3” in the special period of “A's house”. Reclassify to the “people” group.

  According to the electric quantity management system 1 having the above-described configuration, it is possible to cope with a period in which the change pattern of the number of people at home is different from that of daily life due to a family member's trip or business trip. Therefore, the householder (user) of each house 10 can compare the amount of electricity used between his / her household and other households in consideration of a life pattern that is closer to the actual situation, and can grasp the trend of the electricity usage of his / her household. Thus, it becomes easy to obtain an action index for energy saving.

  As another example of the present embodiment, when the classification unit 81 classifies the plurality of houses 10 into a plurality of groups based on the change pattern of the number of people at home, a period designated as a special period for each house 10 A configuration that considers In this configuration, when the classification unit 81 classifies the homes 10, if there is a home 10 for which a special period is set in the storage device 5 (special storage unit), the home unit 10 is within a monitoring period excluding the special period. Classification based on the change pattern of the number of people at home.

  As a result, the home 10 is classified based on the change pattern of the number of people at home excluding a period in which the change pattern of the number of people at home is different from that of daily life due to a family trip or business trip, so the classification is based on the change pattern including the special period. Compared to the case, the reliability of classification by the classification unit 81 is improved. As a result, even if there is a period in which the change pattern of the number of people at home is different from that of daily life due to travel or business trips, according to the electric energy management system 1, the home 10 is classified into an appropriate group, and the user is in the same group. As a result of comparison, an appropriate index for energy saving can be obtained.

  The input unit for special period input is not limited to the home terminal 11 and may be provided in, for example, a television, a portable terminal, a control panel, or the like.

  Other configurations and functions are the same as those of the first embodiment.

  By the way, in each said embodiment, the measuring device 2, the number-of-people monitoring apparatus 3, and the in-home terminal 11 are provided in the house 10, the classification | category part 81, the comparison part 82, the presentation control part 83, and the memory | storage part 84. The reference calculation unit 85 is provided in the center server 8, but is not limited to this configuration.

  That is, for example, some or all of the measuring device 2, the number of people monitoring device 3, and the home terminal (presentation device 4, storage device 5) 11 may be provided in the center server 8. In addition, some or all of the classification unit 81, the comparison unit 82, the presentation control unit 83, the storage unit 84, and the reference calculation unit 85 may be provided in the house 10. A distributed electricity quantity management system 1 in which the classification unit 81, the comparison unit 82, the presentation control unit 83, the storage unit 84, and the reference calculation unit 85 are all provided in the house 10 and the center server 8 is omitted. Then, the in-home terminals 11 communicate with each other between the plurality of houses 10.
