Description

  The present invention relates to a power consumption analysis system, and more particularly to a system for totaling, comparing and analyzing power usage in a plurality of similar facilities such as a chain store group.

  With the recent increase in interest in energy saving or environmental conservation, there is an increasing need for grasping the details of power usage. As part of this, equipment that has the function of measuring and recording the power consumption of facilities at any time is prevalent, especially in factories and buildings. Some of these power measuring devices have a communication function and a function of transmitting measurement values to other information devices. Power meters equipped with these communication functions are connected to the LAN in the facility, so that the history of measured values is accumulated in information devices such as personal computers and servers, and the accumulated data is imported into application software such as spreadsheet software. Therefore, there is an advantage that various analyzes can be performed.

  When measuring and recording the power consumption using the equipment as described above, not only the power consumption of the entire facility is measured, but also the individual power usage such as “lighting” and “cooling / heating” or individual equipment By measuring the amount, useful data can be obtained. In order to measure the breakdown of the amount of power used in this way, it is necessary to select a plurality of locations from the power supply equipment provided in the facility and measure the power. A multi-circuit power measuring instrument capable of measuring power at a plurality of locations with one unit has been commercialized so that it can be used for such applications.

  Generally, a power measuring instrument includes a voltage sensor and a current sensor, and takes a configuration in which power is calculated internally while simultaneously measuring voltage and current. The above-described multi-circuit power measuring device includes one voltage sensor and two or more current sensors, and can measure the power used by two or more circuits having the same voltage. Many existing products can calculate and output power by simply adding power measurements at regular intervals in addition to a simple measurement function. In many cases, the measuring instrument main body is installed near the distribution board of the facility, and is installed so as to measure the voltage of the main circuit in the distribution board. In addition, a current sensor will be installed near the earth leakage breaker in the distribution board to measure the total power consumption. When measuring the breakdown of power consumption using a multi-circuit power meter, install a current sensor in the branch circuit near the safety breaker.

  FIG. 1 shows an example of installation of a multi-circuit power meter that can measure the power consumption of the main and six branch circuits of a single-phase two-wire distribution board at a hypothetical restaurant (store A). It is a schematic diagram. In the figure, 1 denotes a distribution board, and 2, 3, 4a to 4f, and 5a to 5f are parts of the distribution board. 2 is a leakage breaker, and 3 is a main circuit. Reference numerals 5a to 5f denote branch circuits, and reference numerals 4a to 4f denote safety breakers provided in the respective branch circuits.

  6a and 6b are multi-circuit power meters of the same type, and are assigned ID numbers of ID = 1 and ID = 2, respectively. This multi-circuit power meter has four current sensor connection terminals. By connecting current sensors to these connection terminals, the power of up to four circuits can be measured. In addition, this multi-circuit power meter includes a set of voltage input terminals connected to a built-in voltage sensor. In the installation example shown in the figure, the voltage input terminals of both the two measuring instruments are connected to the main circuit by the electric wire 7a so that the voltage of the circuit can be measured. Reference numerals 8a to 8g denote current sensors. 8a to 8f are installed in the branch circuits 5a to 5f, respectively, and 8g is installed in the main circuit. 8g and 8a to 8c are connected to current sensor connection terminals 1 to 4 of the multi-circuit power measuring instrument 6a, and 8d to 8f are connected to current sensor connection terminals 1 to 3 of the multi-circuit power measuring instrument 6a. By this connection, the multi-circuit power measuring device 6a can measure the power of the main circuit and the branch circuits 5a to 5c. The multi-circuit power measuring device 6b can measure the power of the branch circuits 5d to 5f.

  This distribution board has a branch circuit other than 5a to 5f, but does not have a current sensor. For the branch circuit in which the current sensor is not installed as described above, the total sum of the used power can be calculated by subtracting the sum of the measured values of all the branch circuits in which the current sensor is installed from the measured value of the main circuit.

  Note that a CT (Current Transformer) widely used as a current sensor has two conductors and requires two terminals on the measuring instrument side. However, in the example of FIG. 1, only one conductor is omitted. Show.

  Although the power consumption of the main trunk and the six branch circuits can be measured by the installation as described above, a means for the user to see the power value obtained by the measurement is necessary. Although the multi-circuit power meter itself may have a display function, the multi-circuit power meter of FIG. 1 is not included. Instead, this multi-circuit power meter has a communication function and can provide a power value to a personal computer via a network. FIG. 2 is a schematic diagram of connections in which the multi-circuit power measuring devices 6a and 6b are connected to the personal computer 10 via a network. In the figure, 9 is a network hub that connects the three parties. By connecting in this way and operating appropriate software on the personal computer 10, it is possible to display measured values on the screen of the personal computer 10 and to store a history of measured values in the storage device of the personal computer 10. When measuring a plurality of circuits as shown in FIG. 1, since the amount of information increases, it is more convenient to connect to an information device such as a personal computer in this way. For example, by performing data processing on a personal computer, it is possible to easily display a history of measured values as a graph as shown in FIG. In the graph of FIG. 3, the total power used in the branch circuit where no current sensor is installed is displayed as “others”.

  As shown in FIG. 3, when the measurement data is displayed with a circuit name, the user must input the correspondence between the current sensor and the circuit name and store it in the personal computer. This correspondence is held in a tabular data structure as shown in FIG. Here, this data structure is called a measurement circuit table. By referring to the measurement circuit table, software running on a personal computer can display the circuit name as a graph legend. Note that the main flag column in the measurement circuit table indicates whether the corresponding circuit is the main by a logical value.

  In order to display a time-series graph of power consumption as shown in FIG. 3, it is necessary to store a history of measured values of power consumption in a personal computer. This history is held in a tabular data structure as shown in FIG. Here, the table of FIG. 5 is referred to as an electric energy measurement value history table.

  Further, as shown in FIG. 1, when measuring the power of a plurality of circuits, there is an existing product having a function of collecting the measured values of two or more current sensors as a group and displaying the added value. In the case of FIG. 1, for example, the branch circuits 5a and 5b are both air conditioners, 5d and 5e are illumination facilities, and 5c and 5f are wiring to facilities related to cooking. When these are added as a group and displayed in a graph, the result is as shown in FIG.

  In order to display the circuits in groups as shown in FIG. 6, in addition to the measurement circuit table in FIG. 4, the user needs to input how the circuits are grouped and store them in the personal computer. . Such correspondence between groups and circuits is held, for example, with two types of table-type data structures shown in FIGS. Here, the table of FIG. 7 is called a group table, and the table of FIG. 8 is called a group-circuit relation table. The group table shows all groups and their IDs. The group-circuit relationship table indicates which circuits belong to each group. The value in the group ID column of the group-circuit table matches the ID of the column of the same name in the group table. The value of the circuit ID column matches the ID of the column with the same name in the measurement circuit table. In the table of FIG. 8, there are two rows with a group ID of 2 and the circuit IDs are 6 and 7, respectively. This is because the circuit ID is assigned to the “lighting” group with the group ID of 2. This means that “kitchen lighting” of 6 and “guest room lighting” of circuit ID 7 belong. By referring to these three tables by software operating on a personal computer, it is possible to add the measured values of the same group and display them with the group name in the process of creating a graph.

  Thus, when displaying a circuit in a group collectively, it is necessary to install a current sensor in all the circuits corresponding to a group. If a current sensor is not installed in the circuit 5b, the amount of power of the kitchen air conditioner cannot be measured. At this time, if only the circuit ID 4 indicating the room air conditioner is registered in the air conditioner group and addition is performed for each group, a graph in which the power consumption by the kitchen air conditioner is included in “others” is output. As a result, the power used by the air conditioner in the entire store is displayed too small, and the value of “others” is displayed excessively.

  In the above description, in order to store data in the personal computer, tabular data such as the measurement circuit table in FIG. 4, the measured electric energy history table in FIG. 5, the group table in FIG. 7, and the group-circuit relation table in FIG. The structure was introduced. For the purpose of storing data based on these structures, a relational database (RDB) can be used.

  In the above, the system for measuring, recording, and analyzing the electric power used in one store was explained. On the other hand, companies that have business bases scattered around the country, such as the retail and restaurant industries that develop chains, do not complete the analysis of energy use for each store, but accumulate measurement results at multiple facilities. This enables more useful analysis. In order to do this, a system that collects and aggregates data measured at each store in a central data center facility is proposed in Patent Document 1 and the like.

  FIG. 9 is a configuration example of a system for collecting and analyzing measurement data in a plurality of stores as described above. In this figure, it is assumed that the restaurant chain X is a fictitious restaurant chain X, and the store A assumed in the above description of the measurement system at a single store is one of the stores operated by the restaurant chain X.

  In FIG. 9, store A is indicated by reference numeral 18a. Restaurant chain X has store B (18b), store C (18c), and store D (18d) in addition to store A, and has a total of four stores. Stores other than store A are also equipped with power measurement equipment similar to store A.

  In the figure, reference numeral 11 denotes a data center owned by the restaurant chain X, in which a relational database 12 for storing trial electricity of each store is stored and operated in a storage device of the data center 11. The stores 18a to 18d and the data center 12 are connected to the wide area network 13 and can communicate with each other. Here, as the wide area network 13, a public line provided by a communication company, a service such as a wide area Ethernet (registered trademark), the Internet, or the like can be considered. Each store transmits measurement data of power consumption to the data center 11 at a predetermined time interval. The data center 11 adds the received measurement data to the database 12.

  The PC 16 installed in the energy management department 14 of the restaurant chain X is connected to the data center 11 via the intranet 15. Further, analysis software 17 is installed in the PC 16. The analysis software is application software that supports analysis of the power usage history by appropriately extracting data from the database 12 and displaying it in a form such as a table or a graph in accordance with a user operation. The employees of the energy management department can go to the PC 16 and operate the analysis software 17 to perform various analyzes while extracting measurement data from the database 12.

  In the database 12, in addition to the measurement data, data corresponding to the above-described measurement circuit table, group table, and group-circuit relation table is recorded. However, information for store identification is added to the measurement circuit table and the group-circuit relation table so that data in a plurality of stores can be handled.

  The database 12 also stores the store table shown in FIG. This is a table in which stores are registered, and a store ID is assigned to each store in this table.

  Next, tables corresponding to the measurement circuit table and the group-circuit relation table in the database 12 have the structures shown in FIGS. 11 and 12, respectively. 11 is referred to as a central measurement circuit table, and FIG. 12 is referred to as a central group-measurement circuit relationship table. A store ID field is added to each table so that it is possible to identify which store circuit each record indicates.

  As for the table corresponding to the electric energy measurement value history table to which measurement data is added as needed, a store ID field is added to the database 12 as shown in FIG. This table will be referred to as a central electric energy measurement value history table.

  The group relating to the classification of power usage is not unique to each store, so the group table in FIG. 7 can be used as it is in the central data center 12 as well.

  With the mechanism described above, the energy management department 14 can operate the PC 16 and make full use of the database 12 to analyze the amount of power used in the chain store from various viewpoints such as by store and by use.

  The analysis software 17 extracts data from the store table, group table, central measurement circuit table, central group-measurement circuit relationship table, and central power measurement value history table, and presents the table and graph to the user.

JP 2008-9466 A

  By measuring the amount of power used for each branch circuit on the distribution board, accumulating the history, and introducing the group table of FIG. 7 described above, the power used can be classified and analyzed by application. However, as described above, it is necessary to install current sensors for all branch circuits included in each group. This fact does not change even in a large-scale system that aggregates the amount of power used in many stores as shown in FIG.

However, since the investment scale is large in the multi-store aggregation system, the restriction that “all branch circuits for applications to be grouped and analyzed must be measured” becomes more serious.
In chain stores, it is not always reasonable to install a measurement system for power consumption at all stores with a single investment. Rather, there are many cases where it is practical to gradually increase the equipment, such as sequentially installing measurement equipment from stores where it is thought that more useful data can be obtained from analysis. . In addition, there may be a situation in which a difference in the degree of fulfillment of measurement equipment occurs between stores. For example, while it is measured at all stores for guest room lighting, an investment decision can be made to reduce the investment amount by limiting the measurement to kitchen lighting for only some stores.

In this way, when the total value for each application as shown in FIG. 6 is graphed in a situation where there is a difference in the degree of fulfillment of the equipment used to measure the power used for lighting, the following options can be considered for the user.
(1) Remove the power consumption of lighting from the subject of aggregation. At this time, in order to show the total power used, the power used for the lighting application to be measured may be displayed in addition to “Others”. In any case, the output of the analysis software 17 is a graph with no lighting items.
(2) Stores that do not have sufficient lighting measurement equipment will be excluded from aggregation.

  The user needs to grasp the installation status of the equipment in each store and make an appropriate selection for the intention of the analysis. In addition, if the measurement required for performing the desired analysis has not been performed, it is necessary to consider increasing the measurement equipment.

  In order to perform the above (1) and (2), it is necessary for the analysis software 17 to have a function that allows some groups or some stores to be excluded from the analysis target in accordance with the operation of the user. This function can be realized by a known technique, but the user must perform an operation of designating a group or store to be excluded. The operation is made possible by the analysis software 17 having a user interface as shown in FIG.

  In the case of the restaurant chain X shown in the example, since the number of stores is small, the burden on the user is not large. However, the larger the number of stores, the more difficult it is to unify the level of measurement facilities for each store, so there is a high possibility that the above choices (1) and (2) will be forced. In addition, if the number of stores is large and the scale of electrical equipment is large, the burden of operating a personal computer to select a store or application becomes heavy. In addition, the task of formulating a plan to increase the measurement equipment is also burdensome for companies with many stores.

  In view of the above problems, an object of the present invention is to provide a power consumption analysis system for totalizing power usage in a plurality of facilities and improving the convenience for comparison and analysis.

  In order to achieve the above object, the power consumption analysis system according to the present invention can display the measurement values obtained by measuring the power consumption for each use in a plurality of facilities where electrical equipment is used, by a computer via a network. And a facility-based total amount measurement flag table for each facility indicating whether a measurement facility is installed so that the total amount of power used in each application is measured in each facility. When the computer aggregates and displays the amount of power used for each application, it refers to the facility-specific total amount measurement flag table for each application, and the facility does not measure the total amount of power used for the application specified by the user. Processing to automatically exclude the measured values from aggregation. This eliminates the need for the user to input which store to exclude each time the data is tabulated.

  In addition, the power consumption analysis system of the present invention is a power consumption analysis capable of totaling and displaying measured values obtained by measuring the power consumption for each use in a plurality of facilities where electrical equipment is used by a computer via a network. A storage device storing a facility-specific total amount measurement flag table indicating whether or not a measurement facility is installed so that the total amount of power used in each application is measured in each facility; , When totaling and displaying power usage by application, refer to the facility-specific total measurement flag table by application, and automatically measure the measured value in applications where the total power consumption is not measured at the facility specified by the user. In other words, the processing is excluded from aggregation. As a result, the user does not need to input usages to be excluded every time data is aggregated.

  In addition, the power consumption analysis system of the present invention is a power consumption analysis capable of totaling and displaying measured values obtained by measuring the power consumption for each use in a plurality of facilities where electrical equipment is used by a computer via a network. A storage device storing a facility-specific total amount measurement flag table indicating whether or not a measurement facility is installed so that the total amount of power used in each application is measured in each facility; , When displaying the total amount of power used for each application and displaying it, the measured value in the application where the total amount of power used is not measured at the facility designated by the user, referring to the total amount measurement flag table for each application by facility, While not shown as an independent item, a process of adding to the “others” item is performed. As a result, the user can obtain a totaling result in which the measured values for uses that cannot be totaled are added to “others”.

  In addition, the power consumption analysis system of the present invention is a power consumption analysis capable of totaling and displaying measured values obtained by measuring the power consumption for each use in a plurality of facilities where electrical equipment is used by a computer via a network. A storage device storing a facility-specific total amount measurement flag table indicating whether measurement facilities are installed so that the total amount of power used in each application is measured in each facility; With reference to the facility-specific total amount measurement flag table by facility, the facility has a function of displaying a list of facilities where the total amount of power used in the application specified by the user is not measured. Thus, the user can easily grasp which facility is not added to the desired analysis due to the lack of measurement equipment.

  ADVANTAGE OF THE INVENTION According to this invention, the convenience of the electric power usage analysis system which totals and compares and analyzes the electric power usage in a some institution can be improved.

It is a schematic diagram in the case of installing equipment for measuring power usage on the distribution board of store A, which is an imaginary restaurant. This is a connection example in the case where the multi-circuit power measuring devices 6a and 6b and the personal computer 10 are network-connected in the LAN of the store A. It is an example of the bar graph which shows the log | history of the electric power consumption in the shop A. It is a measurement circuit table in the store A. It is an example of the electric energy measurement value history table in the store A. It is an example of the bar graph which shows the log | history of the used electric energy in the shop A created by grouping a branch circuit for every use. It is a group table in the restaurant chain X which manages the store A. It is a group-measurement circuit relation table in the store A. It is a schematic diagram of the structural example of the system which totals the electric power usage of several stores in the restaurant chain X which is an imaginary restaurant chain company. It is a store table in the restaurant chain X. It is a central measurement circuit table in the restaurant chain X. It is a central group-measurement circuit relationship table in the restaurant chain X. It is a central electric energy measurement value history table in the restaurant chain X. In the analysis software, it is an example of a user interface for a user to select a store or a group to be excluded from aggregation. It is an example of the total amount measurement flag table according to use according to facility. It is an example of a non-total amount measurement facility-use table. It is a table contained with the relational database used in the Example of this invention. It is the total amount measurement flag table according to store according to group in restaurant chain X. It is a measurement circuit setting window in the store A. It is a measurement circuit setting window in the store D. It is a display example of a total condition setting window. It is a store status display window regarding the store D. It is an example of the aggregation result window of the restaurant chain X. It is an example of a display of a total condition setting window after operating so that a lighting group may be excluded from a total object. It is an example of the total result window displayed in the state which excluded the lighting group from the total object.

  In the present invention, for each application of power, a series of logical values indicating whether measurement equipment is installed so that the total amount of power used in each facility is measured is stored in the system. This series of information has, for example, a data structure in a table format as shown in FIG. This table will be referred to as a facility-specific total amount measurement flag table. One record of the facility-specific use-based total amount measurement flag table includes a value for identifying a facility (shown as “facility ID” in the figure) and a value for identifying a use (shown as “use ID” in the figure). There is one record for each facility-use combination. Therefore, the number of records in the facility-specific use-based total amount measurement flag table is equal to a value obtained by integrating the number of facilities and the number of uses.

  Each record has a total amount measurement flag. The total amount measurement flag indicates, as a logical value, whether or not the total amount of power used in the application indicated by the use ID of the same record is measured in the facility indicated by the facility ID of the same record. For records whose total amount measurement flag is FALSE, the power for the corresponding use in the corresponding facility is not measured, so it can be determined that it is inappropriate to add to the tabulation.

  The data format for storing information corresponding to the facility-specific usage-specific total amount measurement flag table is not limited to the format shown in FIG. For example, as shown in FIG. 15, it is possible to store in such a manner that only a set of facilities and uses whose total amount has not been measured is registered in the table. When such a format is adopted, it can be determined that it is inappropriate to add to the tabulation the combination in which the corresponding record exists in this table.

  Consider applying the present invention to the example of the restaurant chain X described above. The overall configuration is the same as in FIG. Moreover, the structure of the facility in each store is the same as FIG. 1 and FIG. However, for the store D, only one multi-circuit power meter is installed.

  The present invention is realized by improving the database 12 and the analysis software 17 in FIG.

  FIG. 17 is a list of tables included in the database 12.

  The store table 20 has the structure shown in FIG. 10, and the recorded contents are as described above.

  The group table 21 has the structure shown in FIG. 7, and the recorded contents are as described above.

  The central measurement circuit table 22 has the structure shown in FIG. 11, and the recorded contents are as described above.

  The central group-measurement circuit relationship table 23 has the structure shown in FIG. 12, and the recorded contents are as described above.

  The central electric energy measurement value history table 25 has the structure shown in FIG. 13, and the recorded contents are as described above.

  The store-specific group total amount measurement flag table 24 corresponds to the facility-specific total amount measurement flag table in this system, and has a structure as shown in FIG. The store ID and group ID in FIG. 18 correspond to the facility ID and usage ID in FIG. 15, respectively.

  Among these tables, a new record is added to the store table 20 when the number of stores equipped with measurement facilities increases. A record is added to the group table 21 when a new group is set according to the energy management policy in the restaurant chain X or the like. Records are added to the central measurement circuit table 22 and the central group-measurement circuit relation table 23 when a measurement facility is newly established or expanded at a chain store. Further, when adding a record to the store table 20 or the group table 21, it is necessary to add a corresponding record to the store-specific group total amount measurement flag table 24. It is also necessary to add a record to the central group measurement circuit relation table 23. In addition, as a result of adding a record to the central group-measurement circuit relationship table 23, when all the power of a certain group can be measured in a certain store, the corresponding record in the total amount measurement flag table 24 for each group by store It is necessary to rewrite the total amount measurement flag from FALSE to TRUE.

  A new record is added to the central electric energy measurement value history table 25 every time a measurement value is transmitted from each store.

  Next, the function of the analysis software 17 will be described. The main function of the analysis software 17 is to analyze the power usage history in the chain store, and as an accompanying function, it has a function of inputting the installation status of the measurement equipment.

  The user goes to the PC 16 and operates the user interface of the analysis software 17 to input the installation status of the measurement equipment at each store in the chain. In response to the input, the analysis software 17 creates a new record for the store table 20, the group table 21, the central measurement circuit table 22, the central group-measurement circuit relation table 23, and the store-specific group total amount measurement flag table 24. Add or rewrite existing records.

  Various functions are required for the user interface for inputting the installation status of the measurement equipment, but many of them are similar to the same kind of functions provided in the existing application software, and therefore will not be described in detail here. Here, the user interface for inputting the grouping of the measurement circuit, in which the features of the present invention appear, will be described.

  FIG. 19 is a display example of a user interface for the user to input the installation state of the measurement equipment in a specific store and the grouping of the circuits to be measured. In the figure, the installation status in the store A of the restaurant chain X described so far is displayed.

  The analysis software 17 is assumed to be executed by an operating system having a graphical user interface, and the user interface of FIG. 19 is displayed as one window on the screen of the PC 16. This window is called a measurement circuit setting window 31. The main part of the window is largely divided into left and right. On the right side is a measurement circuit setting unit 32, and the user first operates this to input in which circuit the current sensors 8a to 8g of the power measuring devices 6a and 6b installed in the store are installed. The content input to this part is finally reflected in the central measurement circuit table 22.

  On the other hand, the left grouping setting unit 33 is used to set which group each measurement circuit belongs to. The user registers each circuit as a member of the group by dragging and dropping each circuit name in the measurement circuit setting unit 32 to an area of each group in the grouping setting unit 33. The contents of this operation are finally reflected in the central group-measurement circuit relationship table. There is a total amount measurement check box 34 at the corner of each group area of the grouping setting unit 33. The user checks this check box when all branch circuits to be included in the corresponding group of the target store are included as a member of the group. The state of the total amount measurement check box 34 of each group is finally reflected in the store-specific group total amount measurement flag table 24.

  FIG. 20 shows the same user interface but the state of the store D. Since store D is smaller than other stores, the air conditioner and cooking power are supplied from one branch circuit. However, for lighting, the branch circuit is divided between the kitchen and the seat. Moreover, only one power meter is installed. Since no more than four current sensors can be connected to a single power meter, no current sensor is installed in the branch circuit for kitchen lighting. As a result, all of the power that should be included in the lighting group cannot be measured. Therefore, it is necessary to uncheck the total amount measurement check box for the lighting group in the user or the grouping setting unit 33.

  Next, an operation for analyzing the current usage amount using the analysis software 17 will be described.

  The analysis software 17 has a function of extracting measurement data in a range specified by the user from the database, totaling the extracted data, and displaying the total result in a table or a graph. In order to view the total result, the user first opens a total condition setting window which is a user interface for designating a range of data to be totaled and inputs a condition. Thereafter, when the aggregation start button in the aggregation condition setting window is clicked, the analysis software 17 performs aggregation and the result is displayed as a table or a graph.

  FIG. 21 is a display example of the aggregation condition setting window 41. The aggregation condition setting window 41 includes a group setting unit 42, and the user can designate which group is displayed in the aggregation by operating a check box in the group setting unit 42.

  In the store list section 43, all registered stores are displayed in a table format. Among the stores displayed here, the stores that cannot be included in the total are displayed in gray so that the background in the column is gray and is canceled with diagonal lines so that it cannot be included in the total. In FIG. 21, the column of the store D where the lighting groups cannot be counted is gray. The number of stores display section 44 displays the total number of stores and the number of stores automatically excluded from the aggregation. In FIG. 21, since only the store D is excluded, the number of excluded stores is one.

  At this time, when the user clicks the area of the store D in the store list section 43, the store status display window 50 of the store D appears on the screen. As shown in FIG. 22, the display content of this window indicates that the measurement equipment of the “lighting” group at the store D is insufficient, and the user can confirm the cause of the store D being excluded from the aggregation. From this display, in order to include the store D in the aggregation, the user can grasp that the measurement facility must be increased so that the store D can measure the power for lighting use.

  In the state of FIG. 21, when the aggregation start button 45 in the aggregation condition setting window 41 is clicked, the personal computer 16 causes each table of the database 12 (store-based group total amount measurement flag table 24, central power amount measurement value history table 25, etc.). Referring to Fig. 23, the tabulation process is performed, and a tabulation result window 60 as shown in Fig. 23 is displayed on the screen. This graph shows the total amount of power used by summarizing each group of “air conditioner”, “lighting”, “cooking”, and “others” for each hour. The graph shown here does not include the measured value at the store D. In the lower part of the counting result window 60, “number of target stores: 3” and “number of excluded stores: 1” are displayed.

  From this state, when the user unchecks the illumination of the group setting unit 42, the display is switched as shown in FIG. In conjunction with the operation on the group explanation unit 42, the display of the store list unit 43 and the store number display unit 44 is also automatically updated. By excluding the lighting group from the target, the store D can be included in the tabulation, so the number of excluded stores is zero.

  In the state shown in FIG. 24, when the aggregation start button 45 is clicked, the personal computer 16 refers to each table in the database 12 (total amount measurement flag table 24 for each store group, central power measurement value history table 25, etc.) Processing is performed to display on the screen a count result window 60 that is tabulated so that the measurement values of the illumination group as shown in FIG. 25 are included in the “other” group. In the graph shown here, the measured values in all stores are tabulated.

  In addition, the structure in implementation of this invention and the point which arrange | positions each function are not restricted to the form of FIG.

  For example, not all the functions of the analysis software 17 need be arranged in the PC 16. An arrangement form is also possible in which most of the processing is arranged in an application server installed separately and used from the personal computer 16 in the energy management department 14 via the intranet 15.

  The database 12 is not operated at the data center 11 owned by the restaurant chain X itself, but is operated at the data center of the information service company entrusted by the restaurant chain X. The restaurant chain X is a wide area network such as the Internet. An arrangement form in which a service is used via a connection means is also possible.
