Manage so that the specified storage capacity is not exceeded.

  As described above, the service providing system 110 according to the present embodiment sequentially accumulates the detection data detected by the detection device into units necessary for creating the provision information, and stores them in the information storage unit 114. Therefore, for example, information necessary for providing information over a relatively long period of time, such as “amount used this month” and “amount used this year”, can be stored in a relatively small storage capacity.

  In addition, since the service providing system 110 sequentially deletes the detection information that exceeds the predetermined holding period, the detection information can be stored so as to fit in a predetermined storage capacity.

  Further, in the service providing system 110, for example, when the number of residences 220 to be managed is increased, by setting a predetermined holding period short, the detection information of more residences 220 is stored in the same storage capacity and managed. can do.

  As described above, according to the service providing system 110 according to the present embodiment, in the service providing system 110 that provides predetermined information using the detection information detected by the detection device, it is easy to reduce the data amount of the detection information stored in the storage unit.

FIG. 7A shows an example of detection information 552 in units of 60 minutes (second period) stored in the data storage 431. In the example of FIG. 7A, the detection information 552 in units of 60 minutes includes, as items, “condominium ID”, “account ID”, “measurement date”, “measurement time”, “electricity consumption”, “gas” "Use amount", "Water use amount", etc. are included. Among these, the information of “apartment ID”, “account ID”, and “measurement date” is “apartment ID”, “account ID”, and “measurement date” of the detection information in units of 30 minutes shown in FIG. It is the same as the information of "."

  “Measurement time” is information indicating time in units of one hour. For example, the second detection information at the measurement time “15:00” includes the first detection information at the measurement time “15: 00-15: 29” in FIG. 6A and “15: 30-15: 59”. And the first detection information. That is, the second detection information at the measurement time “15:00” is information indicating the usage amount of electricity, gas, water, and the like in each residence 220 at “15: 00-15: 59”.

  FIG. 7B is an example of data on the electric usage amount 701 at the measurement time “15:00” of the detection information 552 in units of 60 minutes shown in FIG. In the example of FIG. 6B, the electric usage data 601 includes items such as “measurement time”, “main circuit”, “branch circuit 1”, and “branch circuit 2” as items. Yes.

  The item “measurement time” corresponds to the item “measurement time” in the detection information 552 in units of 60 minutes shown in FIG. The items of “main circuit”, “branch circuit 1”, and “branch circuit 2” are the same as the data 601 of the amount of electricity used shown in FIG. In the example of FIG. 7B, the data of the electricity usage amount 701 includes the first detection information at the measurement time “15: 00-15: 29” in FIG. 6A and “15: 30-15: The data on the amount of electricity used by summing up the 59th first detection information is stored. That is, the data on the electricity usage 701 stores data on the electricity usage in the main circuit, the branch circuit 1 and the branch circuit 2 at the measurement time “15: 00-15: 59”.

  As described above, the data amount of the second detection information stored in the detection information 552 in units of 60 minutes is smaller than the data amount of the first detection information stored in the detection information 551 in units of 30 minutes. .

  The second detection information stored in the detection information 552 in units of 60 minutes is, for example, information on the transition of energy usage per hour included in the provision information of “today's usage” to be described later, etc. Used to create

  Returning to FIG. 5 again, the description of the functional configuration of the energy information provision application unit 411 is continued.

  The second information creation unit (second creation unit) 522 uses a plurality of second detection information stored in the 60-minute detection information 552 of the data storage 431 as a unit of one day (third period). If the third detection information that is the detection information can be created, the third detection information is created. The second information creation unit 522 stores the created third detection information in the detection information 553 for each day in the data storage 431.

  FIG. 8 is a diagram illustrating an example of detection information in units of one day and one month according to the first embodiment.

  FIG. 8A shows an example of detection information 553 for each day stored in the data storage 431. In the example of FIG. 8A, the daily detection information 553 includes, as items, “apartment ID”, “account ID”, “measurement date”, “electricity consumption”, “gas usage”, “ Water usage "is included. Each of these items is the same as each item of the detection information 552 in units of 60 minutes shown in FIG.

  8A, for example, the third detection information of the measurement date “20xx.10.01” is, for example, the measurement time “0:00” of the measurement date “20xx.10.01” in FIG. ”To“ 23:00 ”, and is created by summing up the second detection information. In other words, the third detection information on the measurement date “20xx.10.01” is the electric power in each residence 220 from the measurement time “0:00” to “23:00” on the measurement date “20xx.10.01”. Information indicating the amount of gas, water, etc. used.

  Note that the third detection information stored in the detection information 553 for each day is, for example, information on the transition of the energy usage amount for each day included in the provision information of “usage amount for this month” to be described later. Used for creation.

  Returning to FIG. 5, the description of the functional configuration of the energy information provision application unit 411 is further continued.

  The third information creation unit 523 can create fourth detection information, which is detection information in units of one month, using a plurality of pieces of third detection information stored in the detection information 553 in units of days in the data storage 431. In such a case, fourth detection information is created. The third information creation unit 523 stores the created fourth detection information in the detection information 554 for each month in the data storage 431.

  FIG. 8B shows an example of detection information 554 for one month stored in the data storage 431. In the example of FIG. 8B, the detection information 554 for each month includes items “condominium ID”, “account ID”, “measurement month”, “electricity consumption”, “gas usage”, “ Water usage "is included. Among these items, “condominium ID”, “account ID”, “electricity consumption”, “gas consumption”, and “water consumption” are items of detection information 553 for each day shown in FIG. It is the same as each item of.

  “Measurement month” is information indicating the month of measurement in units of one month. For example, the fourth detection information of the measurement month “20xx.09” includes the third detection information from the measurement dates “20xx.09.01” to “20xx.09.30” in FIG. Created. That is, the fourth detection information of the measurement month “20xx.09” is the usage amount of electricity, gas, water, etc. in each residence 220 from the measurement date “20xx.09.01” to “20xx.09.30”. It is information which shows.

  The third detection information stored in the daily unit detection information 553 is used, for example, to create information indicating the transition of the energy usage amount for one month.

  Returning to FIG. 5, the description of the functional configuration of the energy information provision application unit 411 is further continued.

  The configuration of the information creation unit 520 illustrated in FIG. 5 is an example. For example, the first information creation unit 521, the second information creation unit 522, and the third information creation unit 523 may be one information creation unit 520. Further, the information creation unit 520 may further include, for example, a fourth information creation unit that creates detection information in units of one year, or may not include the third information creation unit 523. .

  The information management unit 530 deletes, from the data storage 431, detection information that exceeds the retention period based on information (setting value) indicating the retention period of each detection information stored in the setting information 556 of the data storage 431.

  FIG. 9 is a diagram illustrating an example of setting information according to the first embodiment. In the example of FIG. 9, the setting information 556 includes items such as “detection information”, “minimum holding period”, and “setting value” as items.

  “Detection information” is information indicating the type of detection information. In the “minimum holding period”, the service providing system 110 holds each detection information at least in the “minimum holding period”. The “setting value” is information indicating the retention period of each detection information set by an administrator who manages the service providing system 110, for example.

  Preferably, in the “setting value”, a default value of the information processing system 100 is predetermined and stored, and the administrator changes the setting as necessary.

  In the example of FIG. 9, the information management unit 530 sets a setting value (first value) corresponding to “detection information in units of 30 minutes” in FIG. 9 among the first detection information stored in the detection information 551 in units of 30 minutes. Information exceeding the detection information retention period) is deleted. In this case, since the first detection information for one week plus one day is stored in the detection information 551 in units of 30 minutes, the energy information provision application unit 411 stores the energy information for the past week (for example, the amount of electricity used). It is possible to analyze various changes and provide various information.

  Similarly, the information management unit 530 sets a setting value (second detection information) corresponding to the “detection information in units of 60 minutes” in FIG. 9 among the second detection information stored in the detection information 552 in units of 60 minutes. The information exceeding “2 days” is deleted from the detection information 552 in units of 60 minutes.

  Also, the information management unit 530 sets a setting value corresponding to “daily detection information” in FIG. 9 among the third detection information stored in the daily detection information 553 (retention of the third detection information). Period) Information exceeding “2 months” is deleted from the detection information 553 in units of one day.

  Furthermore, the information management unit 530 sets the setting value (the fourth detection information of the fourth detection information) corresponding to the “one month unit detection information” in FIG. 9 among the fourth detection information stored in the one month unit detection information 554. (Retention period) Information exceeding “2 years” is deleted from detection information 553 in units of one month.

  The setting unit 540 is a means for setting (changing) the “setting value” of the setting information 556 shown in FIG. For example, the setting unit 540 displays a setting screen for the setting information 556 on the display unit 307 and the like in FIG. 3 according to the operation of the administrator of the service providing system 110, and the input setting value is displayed in the setting information 556. Remember.

  Thereby, for example, when the number of residences 220 in which the energy information providing application unit 411 manages the detection information increases, the retention period (setting value) of each detection information is reduced without increasing the capacity of the data storage 431. This can be handled.

  As described above, in the service providing system 110 according to the present embodiment, the data amount of the detection information stored in the data storage 431 does not exceed a predetermined storage capacity by setting the “setting value” of the setting information 556. Easy to manage.

  The information providing unit 550 uses the detection information 551 in units of 30 minutes, detection information 552 in units of 60 minutes, detection information 553 in units of days, detection information 554 in units of months, and the like stored in the data storage 431. Various provision information is provided to the user of the terminal 130.

  For example, the information providing unit 550 uses the second detection information for two days stored in the detection information 552 in units of 60 minutes to obtain “today's energy usage” and “hourly energy usage transition”. Information such as “comparison with yesterday's energy consumption” can be provided.

  Similarly, the information providing unit 550 uses the third detection information for two months stored in the detection information 553 for each day to generate “energy usage amount for this month” and “transition of energy usage amount for each day”. Information such as “Comparison with last month's energy consumption” can be provided. Specific examples of provided information will be described later.

<Process flow>
FIG. 10 is a flowchart illustrating an example of detection information update processing according to the first embodiment.

  In step S1001, the acquisition unit 510 in FIG. 5 executes the processing after step S1002 when a predetermined time (first period) has elapsed since the previous acquisition of the first detection information. Here, the following description will be made assuming that the predetermined time is 30 minutes.

  In step S <b> 1002, the acquisition unit 510 acquires the first detection information from the energy information management server 121 using the external system cooperation unit 422 and stores the first detection information in the detection information 551 in units of 30 minutes in the data storage 431. At this time, the acquired first detection information includes, for example, electricity, gas, and water detected by a detection device such as a distribution board 222, a gas meter 223, and a water meter 224 installed in each residence 220 of the apartment 210. And so on.

  In step S1003, the first information creation unit 521 in FIG. 5 uses the first detection information stored in the detection information 551 in units of 30 minutes by the acquisition unit 510 as the second detection information that is in units of 60 minutes. It is determined whether or not detection information can be created.

  For example, in the detection information 551 in 30-minute units shown in FIG. 6A, when the first detection information at the measurement time “15: 30-15: 59” is newly added, the measurement time “15:00” The second detection information can be created. In this case, the first information creation unit 521 creates second detection information that is detection information in units of 60 minutes using the first detection information stored in the detection information 551 in units of 30 minutes by the acquisition unit 510. Judge that you can.

  On the other hand, in the detection information 551 in units of 30 minutes, when the first detection information at the measurement time “16: 00-16: 29” is newly added, the second detection information at the measurement time “16:00” is changed. In order to create, the measurement time “16: 30-16: 59” information is insufficient. In this case, the first information creation unit 521 creates second detection information that is detection information in units of 60 minutes using the first detection information stored in the detection information 551 in units of 30 minutes by the acquisition unit 510. Judge that it is not possible.

  If the first information creation unit 521 determines that the second detection information, which is 60-minute detection information, cannot be created, the process proceeds to step S1009. On the other hand, if the first information creation unit 521 determines that the second detection information, which is 60-minute detection information, can be created, the process proceeds to step S1004.

  In step S1004, the first information creation unit 521 uses the first detection information stored in the detection information 551 in units of 30 minutes by the acquisition unit 510 to perform second detection that is detection information in units of 60 minutes. Information is created and stored in the data storage 431.

  For example, in the detection information 551 in units of 30 minutes shown in FIG. 6A, it is assumed that the first detection information at the measurement time “15: 30-15: 59” is newly added. In this case, the first information creation unit 521 aggregates the first detection information at the measurement time “15: 00-15: 29” and the first detection information at “15: 30-15: 50”. The second detection information at the measurement time “15:00” is created. Further, the first information creation unit 521 stores the created second detection information at the measurement time “15:00” in the detection information 552 for every 60 minutes in the data storage 431.

  In step S1005, the second information creation unit 522 in FIG. 5 uses the second detection information stored in the 60-minute detection information 552 by the first information creation unit 521 as the detection information for each day. It is determined whether or not certain third detection information can be created.

  For example, in the 60-minute detection information 552 shown in FIG. 7A, when the second detection information at the measurement time “15:00” is newly added, the measurement date “20xx.10.01” In order to create the detection information of 3, the information after 16:00 is insufficient. In this case, the second information creation unit 522 uses the second detection information stored in the detection information 552 in units of 60 minutes by the first information creation unit 521, and detects third information that is detection information in units of one day. It is determined that detection information cannot be created.

  On the other hand, in the detection information 552 in units of 60 minutes, when the second detection information of the measurement times “00:00” to “23:00” on the measurement date “20xx.10.01” is prepared, the measurement date “20xx. The third detection information of “10.01” can be created. In this case, the second information creation unit 522 uses the second detection information stored in the detection information 552 in units of 60 minutes by the first information creation unit 521, and detects third information that is detection information in units of one day. It is determined that detection information can be created.

  If the second information creation unit 522 determines that the third detection information, which is detection information for each day, cannot be created, the process proceeds to step S1009. On the other hand, if the second information creation unit 522 determines that the third detection information, which is the detection information for each day, can be created, the process proceeds to step S1006.

  In step S1006, the second information creation unit 522 uses the second detection information stored in the 60-minute detection information 552 by the first information creation unit 521 as detection information for one day. Third detection information is created and stored in the data storage 431.

  For example, in the detection information 552 in units of 60 minutes shown in FIG. 7A, the second detection information of the measurement times “00:00” to “23:00” on the measurement date “20xx.10.01” is provided. Shall. In this case, the second information creation unit 522 aggregates the second detection information of the measurement times “00:00” to “23:00” on the measurement date “20xx.10.01” and the measurement date “20xx”. .10.01 "is generated. Further, the second information creation unit 522 stores the created third detection information of the measurement date “20xx.10.01” in the detection information 553 for each day in the data storage 431.

  In step S1007, the third information creation unit 523 in FIG. 5 is detection information in units of one month using the third detection information stored in the detection information 553 for each day by the second information creation unit 522. It is determined whether or not the fourth detection information can be created.

  For example, in the detection information 553 in units of one day shown in FIG. 8A, when the third detection information of the measurement date “20xx.10.01” is newly added, the number of the measurement month “20xx.10” In order to create detection information No. 4, information after “20xx.10.02” is insufficient. In this case, the third information creation unit 523 uses the third detection information stored in the detection information 553 by the second information creation unit 522 in the first day detection information 553. It is determined that detection information cannot be created.

  On the other hand, when the third detection information of the measurement date “20xx.09.30” is newly added in the detection information 553 for each day, the fourth detection information of the measurement month “20xx.09” is created. be able to. In this case, the third information creation unit 523 uses the third detection information stored in the detection information 553 by the second information creation unit 522 in the first day detection information 553. It is determined that detection information can be created.

  If the third information creation unit 523 determines that the fourth detection information, which is detection information for one month, cannot be created, the process proceeds to step S1009. On the other hand, if the third information creation unit 523 determines that the fourth detection information, which is detection information for one month, can be created, the process proceeds to step S1008.

  In step S1008, the third information creation unit 523 uses the third detection information stored in the detection information 553 by the second information creation unit 522 as the detection information for one month. Fourth detection information is created and stored in the data storage 431.

  For example, in the detection information 553 for each day shown in FIG. 8A, it is assumed that the third detection information for the measurement dates “20xx.09.01” to “20xx.09.30” is provided. In this case, the third information creation unit 523 aggregates the third detection information of the measurement dates “20xx.09.01” to “20xx.09.30” to obtain the fourth of the measurement month “20xx.09”. Create discovery information. The third information creation unit 523 stores the created fourth detection information of the measurement month “20xx.09” in the detection information 554 in units of one month in the data storage 431.

  In step S1009, the information management unit 530 in FIG. 5 determines whether there is detection information whose retention period has passed among the detection information stored in the data storage 431.

  If there is no detection information that has passed the holding period, the information management unit 530 ends the process. On the other hand, when there is detection information that has passed the holding period, the information management unit 530 causes the process to proceed to step S1010.

  In step S1010, the information management unit 530 deletes the detection information whose retention period has elapsed from the data storage 431.

  For example, the information management unit 530 includes the first detection information stored in the 30-minute detection information 551 of the data storage 431 and the first detection that has passed the setting value “1 week + 1 day” of the setting information 556. The information is deleted from the detection information 551 in units of 30 minutes.

  Similarly, the information management unit 530 includes, among the second detection information stored in the 60-minute detection information 552 of the data storage 431, the second detection information that has passed the setting value “2 days” of the setting information 556. Are deleted from the detection information 552 in units of 60 minutes.

  In addition, the information management unit 530 includes third detection information that has passed the set value “2 months” of the setting information 556 among the third detection information stored in the detection information 553 for each day of the data storage 431. Delete from the detection information 553 for each day.

  Further, the information management unit 530 includes the fourth detection information stored in the detection information 554 in units of one month in the data storage 431 and the fourth detection information that has passed the setting value “2 years” of the setting information 556. Delete from the detection information 554 for one month.

  Through the above processing, the energy information provision application unit 411 sequentially aggregates the first detection information acquired from the energy information management server 121 every 30 minutes into units necessary to create the provision information, and the data Store in the storage 431. Therefore, for example, information necessary for providing information over a relatively long period of time, such as “amount used this month” and “amount used this year”, can be stored in a relatively small storage capacity.

  In addition, the energy information providing application unit 411 sequentially deletes the detection information that exceeds the predetermined holding period from the data storage 431, and therefore manages the detection information so that it falls within a predetermined storage capacity. Becomes easier.

  Furthermore, the energy information provision application part 411 changes the setting value of the holding period memorize | stored in the setting information 556 short, for example, when the residence 220 to manage increases, By the same storage capacity, more residences 220 Detection information can be stored and managed.

  As described above, according to the service providing system 110 according to the present embodiment, in the service providing system 110 that provides predetermined information using the detection information detected by the detection device, it is easy to reduce the data amount of the detection information stored in the storage unit. Can be reduced and managed.

<Example of provided information>
Here, an example of provided information provided by the information providing unit 550 of FIG. 5 using the detection information stored in the data storage 431 will be described.

  11 to 13 are diagrams illustrating examples of information provided by the information providing unit according to the first embodiment.

  When a user registered in the service providing system 110 accesses the service providing system 110 using a web browser or the like of the information terminal 130, for example, a main menu 1100 as illustrated in FIG. 11 is displayed on the display unit 307 of the information terminal 130. Is displayed.

  In the example of FIG. 11, the main menu 1100 includes electricity usage information 1101, gas usage information 1102, water usage information 1103 and the like provided by the energy information provision application unit 411. The main menu 1100 includes, for example, information provided by the environment information providing application unit 412 such as the environment information details 1104, information provided by the apartment information providing application unit 413 such as the shared facility reservation 1105, and the like. May be.

  The user selects, for example, the electricity usage information 1101 in the main menu 1100, so that “today” electricity usage information 1200 as shown in FIG. 12 is displayed on the display unit 307 of the information terminal 130. Can be displayed.

  In the example of FIG. 12, “Today” electricity usage information 1200 includes a button 1201 for displaying “Today” electricity usage and a button 1202 for displaying “Current Month” electricity usage. It is displayed. FIG. 12 shows an example of provision information (provided information of the first format) when the button 1201 for displaying the electricity usage amount of “today” is selected.

  For example, information 1203 indicating today's electricity usage, a bar graph 1204 indicating today's electricity usage change, a line graph 1205 indicating yesterday's electricity usage change, Information about the amount of electricity used by hour 1206 and the like are included.

  Among these, the information 1203 indicating the amount of electricity used today is calculated by, for example, totaling the first detection information stored in the detection information 551 in units of 30 minutes in the data storage 431. Also, the bar graph 1204 indicating the transition of the electricity usage today and the line graph 1205 indicating the transition of the electricity usage yesterday are, for example, the second detection stored in the detection information 552 in 60-minute units of the data storage 431. Created using information. Furthermore, in the hourly electricity usage information 1206, for example, the electricity usage corresponding to the bar graph 1204 indicating the transition of today's electricity usage is displayed numerically every hour.

  Preferably, when the hourly electricity usage exceeds a predetermined target value 1207 (for example, 1.5 kWh) for each hour, the information providing unit 550 displays the bar graph 1208 with a different color. Encourage users to save power. Further, based on the transition of the electricity usage data 601 shown in FIG. 6B, for example, when the electricity usage of the branch circuit related to the air conditioner is large, the information providing unit 550 “decreases the set temperature of the air conditioner once. A message 1209 such as “Let ’s do it” is displayed. The information providing unit 550 may provide useful information to the user by such a message 1209, for example.

  In addition, the user selects the button 1202 for displaying the electricity usage amount of “this month” in FIG. 12 to thereby display information 1300 on the electricity usage amount of “this month” as shown in FIG. 13 (second format). Provided information) can be displayed.

  For example, information 1301 indicating the amount of electricity used in this month, a bar graph 1302 indicating a change in the amount of electricity used this month, a line graph 1303 indicating a change in the amount of electricity used last month, Information on the amount of electricity used by day 1304 is included.

  Among these, the information 1301 indicating the amount of electricity used this month is, for example, the first detection information stored in the detection information 551 in 30-minute units of the data storage 431 and the first detection information stored in the detection information 553 in one-day units. It is calculated by adding up the detection information of 3 and the like. In addition, a bar graph 1302 indicating a transition of electricity usage in this month and a line graph 1303 indicating a transition of electricity usage in the last month include, for example, the third detection stored in the detection information 553 for each day in the data storage 431. Created using information. Furthermore, in the daily electricity usage information 1304, for example, the electricity usage corresponding to the bar graph 1302 indicating the transition of the electricity usage for this month is displayed numerically every day.

  Similarly, the information providing unit 550 can provide information on the amount of electricity used for “this year” using the fourth detection information stored in the detection information 554 in units of one month in the data storage 431, for example. it can.

  As described above, the energy information provision application unit 411 sequentially aggregates the first detection information acquired from the energy information management server 121 every 30 minutes into units necessary for creating the provision information, 431. As a result, the energy information providing application unit 411 can store information on the amount of energy used over a long period of time within a predetermined storage capacity, and can also store information on the amount of energy used as described above. It can be easily provided.

[Second Embodiment]
In the information update process according to the first embodiment illustrated in FIG. 10, the information management unit 530 of the energy information provision application unit 411 detects that the holding period has passed after the acquisition unit 510 acquires the first detection information. The presence or absence of information was judged. However, this process is merely an example, and the information management unit 530 may execute a detection information deletion process that has passed the holding period at a timing different from the information update process.

  FIG. 14 is a flowchart illustrating an example of detection information update processing and deletion processing according to the second embodiment.

  FIG. 14A shows an example of detection information update processing according to the second embodiment. In FIG. 14A, the processing of steps S1001 to S1008 is the same as the processing of steps S1001 to S1008 of the detection information update processing according to the first embodiment shown in FIG. In the detection information update process according to the second embodiment shown in FIG. 14A, the detection information deletion process shown in steps S1009 and S1010 of FIG. 10 is performed after the processes of steps S1001 to S1008 are performed. The process ends without executing.

  FIG. 14B is a flowchart illustrating an example of detection information deletion processing according to the second embodiment.

  In step S1401, the energy information provision application unit 411 executes the processing after step S1402 when a predetermined time comes.

  In step S1402, the information management unit 530 in FIG. 5 determines whether there is detection information that has passed the holding period among the detection information stored in the data storage 431. The specific processing content may be the same as the processing in step S1009 of FIG.

  If there is no detection information that has passed the holding period, the information management unit 530 ends the process. On the other hand, when there is detected information that has passed the holding period, the information management unit 530 shifts the processing to step S1403.

  In step S1403, the information management unit 530 deletes the detection information whose retention period has elapsed from the data storage 431.

  For example, the information management unit 530 includes the first detection information stored in the 30-minute detection information 551 of the data storage 431 and the first detection that has passed the setting value “1 week + 1 day” of the setting information 556. The information is deleted from the detection information 551 in units of 30 minutes.

  Similarly, the information management unit 530 includes, among the second detection information stored in the 60-minute detection information 552 of the data storage 431, the second detection information that has passed the setting value “2 days” of the setting information 556. Are deleted from the detection information 552 in units of 60 minutes.

  In addition, the information management unit 530 includes third detection information that has passed the set value “2 months” of the setting information 556 among the third detection information stored in the detection information 553 for each day of the data storage 431. Delete from the detection information 553 for each day.

  Further, the information management unit 530 includes the fourth detection information stored in the detection information 554 in units of one month in the data storage 431 and the fourth detection information that has passed the setting value “2 years” of the setting information 556. Delete from the detection information 554 for one month.

  Note that the predetermined time in step S1401 may be, for example, once a day (for example, midnight) or multiple times a day (for example, every hour). .

  As another example, the deletion process in steps S1402 and S1403 in FIG. 14B is executed when the data amount of the detection information stored in the data storage 431 reaches a predetermined value. It may be.

[Other Embodiments]
The values for each period of 30 minutes (first period), 60 minutes (second period), one day (third period), and one month (fourth period) shown in each of the above embodiments are examples. Other values may also be used. For example, the first period may be 10 minutes or 20 minutes.

  In addition, the information creation unit 520 may further include a fourth information creation unit that creates detection information in units of one year (an example of a fifth period), for example. Furthermore, the information creation unit 520 may further include, for example, a fifth information creation unit that creates detection information in units of 10 years (an example of a sixth period).

  Furthermore, the first detection information detected by the detection device may be detection information other than energy relations such as electricity, gas, and water. For example, the first detection information may be detection information such as a distribution time of a content distribution service in each residence 220, a data amount, or the like. Further, the first detection information may be detection information of environmental information (for example, temperature, humidity, etc.) installed at a plurality of points in the city.
