Description

  The present invention relates to a resource management system, an information providing apparatus, and a program for causing a computer to execute a process for managing the consumption of the resource in an aggregate of a plurality of consumption units that consume the resource.

  Resources consumed at homes and offices include power, gas, and water. There is provided a resource management system for managing resources by displaying the usage amounts of these resources and promoting the saving of the usage amounts. As one of them, an energy management system (EMS) for managing electric power is known. EMS has been developed under the names HEMS for residential buildings, BEMS for commercial buildings, FEMS for factories, CEMS for the entire region, and MEMS for condominiums, depending on the management target.

  For example, as a resource management system (MEMS) for multi-family housing, a system has been proposed that uses a housing information panel to instruct a change in the operating state of equipment when requested to reduce resource usage. (For example, refer to Patent Document 1). Here, the collective housing refers to a collective of residences that constitute one building, such as a condominium or an apartment, or an aggregate of residences (sections) that constitute one region, such as a condominium.

  However, in the above system, since the power consumption is managed in units of apartments, there is a problem that the management is not necessarily appropriate for the residents of individual sections as consumption units that consume resources. This is because the resource consumption that should be the management target in each section is not known, and therefore it is not possible to manage appropriately in each section.

  Accordingly, it has been desired to provide a system that can manage the consumption of resources even in individual consumption units.

  In view of the above problems, the present invention is a resource management system for managing consumption of a resource in an aggregate of a plurality of consumption units that consumes the resource, and measuring the consumption of the resource for each of the plurality of consumption units. A plurality of measurement units, a storage unit that stores consumption amounts of resources of a plurality of consumption units measured by the plurality of measurement units as history information, and a target consumption amount of resources based on the history information stored in the storage unit A target determination unit for determining a consumption target by calculating the consumption target, and the one or more consumption units by transmitting the consumption target determined by the target determination unit to one or more consumption units requesting acquisition of the consumption target A resource management system is provided, including an information providing unit that provides information.

  According to the present invention, it is possible to manage resource consumption even in individual consumption units.

  The resource management system manages resource consumption in an aggregate of a plurality of consumption units that consume resources. Resources are consumer goods that are uniformly provided over a wide area, such as electricity, gas, and water, and whose consumption can be measured. The unit of consumption that consumes resources is the housing (classification) that consumes resources, and the aggregate is a collection of residences that constitute one area, such as a collection of residences that constitute a condominium or an apartment, or a condominium. It is. Hereinafter, the resource is assumed to be electric power, the collective is assumed to be a collective housing, and the consumption unit is classified into detail.

  FIG. 1 is a diagram illustrating a configuration example of a resource management system. The resource management system is connected to the measurement units 11 to 13 and the display units 14 and 15 installed in the respective sections 1, 2 and 4 in the apartment house 100, the communication network 16 such as a LAN or the Internet, and the communication network 16. And an information providing device 17.

  In the example illustrated in FIG. 1, the display unit is not installed in the category 1, and neither the measurement unit nor the display unit is installed in the category 3, but is not limited thereto. Therefore, a display unit may be installed in the category 1, and either a measurement unit or a display unit, or both may be installed in the category 3. In addition, the display unit is not limited to being in the section, and may be disposed outside the section, or may be disposed outside the collective housing 100 like the display unit 15. The display unit can be provided only with a section that requires display.

  When the measurement units 11 to 13 and the display units 14 and 15 are connected to the communication network 16 by radio, an access point can be provided in the communication network 16. Thereby, it is possible to communicate with the information providing apparatus 17 via the access point. The plurality of measuring units 11 to 13 and the display units 14 and 15 and the information providing device 17 may be directly connected by a cable or the like without using the communication network 16. The communication network 16 is not limited to one communication network, and may be composed of two or more communication networks connected by a relay device such as a router or a proxy server.

  The measuring units 11 to 13 installed in each of the sections 1, 2, and 4 measure the amount of power consumed in each of the sections 1, 2, and 4, and provide the measured power amount via the communication network 16. 17 to send. Each measurement part 11-13 measures the electric energy consumed per time, for example. Here, the power consumption of each section is measured, but the power consumption of each individual device or room in each section may be measured. The individual devices may be air conditioning devices, lighting devices, or other devices.

  The measurement units 11 to 13 include a power consumption sensor for measuring the power consumption, and a controller and an interface that transmit the measured power consumption to the information providing device 17. The measurement and transmission of the power consumption can be performed at regular time intervals, for example, every 5 minutes. In addition, the measurement and transmission in the measurement units 11 to 13 are performed independently in parallel in each section of the apartment house 100.

  The information providing apparatus 17 stores the power consumption amount transmitted from each of the measurement units 11 to 13 as history information. And the information provision apparatus 17 determines the power consumption target with respect to each division by calculating the power consumption (target consumption) used as a management target for each division based on the stored history information. This consumption target is a target value for daily power consumption or monthly power consumption in each category.

  The information providing device 17 provides the consumption targets determined for the respective categories 2 and 4 by transmitting them to the display units 14 and 15 via the communication network 16. The reason for limiting to categories 2 and 4 is that only categories 2 and 4 have a display unit that can receive and display the consumption target. The display units 14 and 15 receive the consumption target, and present it to the residents of the sections 2 and 4 by displaying them on the screen. Thereby, the resident of each division 2 and 4 can know the target value of own power consumption.

  The information providing device 17 is, for example, a server device, and has a hardware configuration as shown in FIG. 2 in order to perform the above processing. The information providing device 17 has the same configuration as a general PC and includes a CPU 20, ROM 21, RAM 22, HDD 23, and communication I / F 24. The CPU 20 controls the information providing device 17 as a whole. The ROM 21 stores a program for starting up the information providing device 17 and a program for controlling hardware connected to the information providing device 17. The RAM 22 provides a work area when the CPU 20 performs processing. The HDD 23 is a non-volatile memory and stores a program and various data for realizing the above processing. The communication I / F 24 is an interface that is connected to the plurality of measurement units 11 to 13 and the display units 14 and 15 via the communication network 16 and enables communication with them.

  The display units 14 and 15 shown in FIG. 1 also include hardware similar to that of the information providing device 17, and in addition, a display screen for displaying a consumption target, and an interface for controlling display on the display screen Can be configured. Examples of the display units 14 and 15 include PCs, tablet terminals, portable terminals such as smartphones, interphones, and the like.

  The information providing apparatus 17 can include a functional unit as shown in FIG. 3 in order to realize the function. These functional units can be realized by the CPU 20 reading out and executing the HDD 23 or a program stored in the HDD 23. The information providing device 17 includes an information storage unit 30, a target determining unit 31, and an information providing unit 32 as functional units.

  The information storage unit 30 stores the power consumption received from each of the measurement units 11 to 13 as history information. The history information can be stored using, for example, the table shown in FIG. 4 and can be configured on the information providing apparatus 17 using a relational database or the like.

  In FIG. 4, together with identification information (section ID) for identifying each section, the measured power consumption (Wh), the date and time when the measurement was started, and the date and time when the measurement was completed are stored in association with each other. ing. Here, only the category ID “001” is illustrated, but history information of other IDs can also be stored. A table can be provided for each section, and history information can be managed for each section.

  The information storage unit 30 may perpetuate the power consumption stored as history information. The measuring units 11 to 13 can generate a pulse signal each time a predetermined power consumption is reached, for example. Thereby, the power consumption per time can be calculated from the accumulated value of the power consumption until a certain pulse signal is generated and the next pulse signal is generated.

  The target determining unit 31 calculates a target consumption amount according to the flowcharts shown in FIGS. 5 and 6 and determines it as a consumption target. The target determination unit 31 determines a consumption target for each category. The information providing unit 32 provides each consumption target determined by the target determining unit 31 to each division by transmitting it to each division. The display unit installed or arranged in each section receives the consumption target and displays it to the resident by displaying it.

  With reference to FIGS. 5 and 6, the process for determining the target consumption will be described in detail. First, the overall flow of the processing will be described with reference to FIG. The target consumption can be, for example, a daily target that is a target value of power consumption consumed on a day and a monthly target that is a target value of power consumption consumed on a month. The time unit is not limited to days and months, but may be a fine time unit that divides a day into daytime or nighttime, or a long time unit such as a climate classification such as four seasons or one year. There may be. Hereinafter, the target consumption will be described as a daily target and a monthly target.

  The process starts from step 500, and in step 505, it is determined whether it is the beginning of the month. That is, it is determined whether or not the day on which this processing is performed is the first day of the month (○ is an arbitrary number from 1 to 12) on the calendar. If it is the beginning of the month, the process proceeds to step 510. If it is not the beginning of the month, the process proceeds to step 520, and this process ends.

  In step 510, a daily target is calculated. The calculation of the daily target will be described in detail with reference to FIG. The daily target is calculated as a daily target numerical value. In step 515, the calculated daily target numerical value is integrated by the number of days in the current month to calculate a monthly target numerical value, which is set as the monthly target. These daily goals and monthly goals are stored and accumulated in the information storage unit 30.

  The daily target is calculated using, for example, history information of an arbitrary period of the previous month stored in the information storage unit 30, but the history information of that period may not be stored in the information storage unit 30. . This is because the power consumption may not be measured due to a failure of the measuring units 11 to 13 or the like. As described above, when there is no history information for an arbitrary period of the previous month in the information storage unit 30, a predetermined daily target numerical value is set as a daily target, and the monthly target numerical value is used by using the daily target numerical value. Numerical values can be calculated. When the calculated monthly target numerical value is set as the monthly target and the daily target and the monthly target are stored in the information storage unit 30, the process proceeds to step 520, and this process is terminated.

  With reference to FIG. 6, the process which calculates the daily target in step 510 is demonstrated in detail. In step 605, the daily average of power consumption at the end of the previous month is calculated for each category. Specifically, the daily average of power consumption for the 7th day of the previous month is calculated. For example, if the previous month is August, the power consumption for 7 days from August 25 to August 31 is calculated using the history information stored in the information storage unit 30, and the calculated 7 days The daily average is calculated from the power consumption.

  In step 610, it is determined whether or not calculation has been performed up to the last category. If not calculated up to the last category, the process returns to step 605 to calculate the daily average of the next category that has not yet been calculated. If it has been calculated up to the last category, the process proceeds to step 615. In step 615, a representative value is calculated from a plurality of daily averages calculated for a plurality of categories, and the representative value is set as a daily target numerical value. In step 620, the process is terminated.

  The representative value can be, for example, the median value of a plurality of daily averages calculated for a plurality of categories. The representative value is not limited to this, and may be a statistically calculated representative value such as a quartile or an average value. Here, the median is the value of data located at the center when the sample data are arranged in ascending order. The quartile is a value of data located at 1/4, 1/2, 3/4 from the smallest when sample data are arranged in ascending order.

  The sample data used for the above calculation takes into consideration the change in conditions that affect the consumption of resources such as the climate, and as shown in the above example, the daily average calculated from the power consumption for the end of the previous month that is as recent as possible is used. Can be used. However, this is an example, and is not limited to the last month. In the above example, the calculation is performed using the power consumption for 7 days in order to improve the statistical reliability. However, the calculation is not limited to this, but it is for 5 days or 2 weeks. May be. In short, it is only necessary that the target is determined based on the power consumption amount for each section and the target has an appropriate content.

  As monthly target numerical values, consumption targets may be set in stages, such as the median value in the quartile being the first consumption target and the following first quartile being the second consumption target. As a result, a section that has exceeded the second consumption target can be used as the first consumption target thereafter, so that a state in which the target has been lost can be avoided as much as possible.

  The information providing unit 32 can provide the consumption target determined by the target determining unit 31 by transmitting it. It is also possible to provide it accordingly. For example, by specifying a specific URL (Uniform Resource Locator) for a consumption target, the consumption target can be copied and held in a storage area that can be referred to using HTTP (Hyper-Text Transfer Protocol). For this reason, the information provision part 32 can provide the consumption target in response to the access request to the URL.

  The display units 14 and 15 can display the daily target and the monthly target as shown in FIG. 7 as the target consumption as the management target by accessing the URL provided from the information providing unit 32. . In the example shown in FIG. 7, the target of power consumption for this month is 300 kWh, and the current target is 10 kWh. The display content shown in FIG. 7 may be generated by the information providing unit 32, or generated by the display units 14 and 15 acquiring necessary information from the information providing unit 32 and processing the information. It may be what you did.

  FIG. 8 is a functional block diagram showing a second embodiment of the information providing apparatus 17. The information providing device 17 has the same configuration as the information providing device 17 shown in FIG. 3, but further includes an attribute storage unit 33 as a functional unit. Since the information storage unit 30 and the like have already been described, only the attribute storage unit 33 will be described here. The attribute storage unit 33 stores attribute information related to resources of each section of the apartment house. Similarly to the information storage unit 30, the attribute storage unit 33 is configured using a relational database or the like, and is arranged on the information providing device 17 so that the target determination unit 31 can refer to it. The attribute information can be given as, for example, a table shown in FIG.

  As shown in FIG. 9, for each category ID for identifying a category, attribute information representing the characteristics of the category, such as the layout of the category and the floor type, is stored. The floor plan is information such as 3LDK and 4LDK, and the floor type is information such as the lowest floor, intermediate floor, and top floor. The floor type is divided into three floors, and may be information such as a lower floor, a middle floor, and an upper floor, or may be a specific floor. The attribute storage unit 33 can store not only attribute information but also index data that is likely to affect resource consumption, such as a family structure, a life type, and a standard at-home time zone.

  The family structure includes information on the number of family members and sequels. The life type is information of a morning type, a day type, and a night type classified according to a time zone in which the resident mainly operates within the category. The at-home time zone is a time zone in which at least one resident of the division is in the division, for example, from 8:00 to 8:00 the next morning.

  In determining the consumption target, the target determination unit 31 uses the history information for each category stored in the information storage unit 30 and the attribute information for each category stored in the attribute storage unit 33. In calculating the above-described daily and monthly target numerical values, the target determining unit 31 uses only the history information of the category having the attribute for each attribute, and uses the daily target numerical value and the monthly target numerical value. Is calculated. In this way, by determining the consumption target using only the history information of the category having the same attribute, it is possible to provide the consumption target reflecting the attribute.

  The information providing unit 32 can transmit and display the daily target and the monthly target shown in FIG. 8 to the display units 14 and 15 for each category. It is not limited to. For example, information on the power consumption of each section as shown in FIGS. 10 and 11 can be provided and displayed on the display units 14 and 15. FIG. 10 is a graph showing the relationship between time and accumulated power consumption together with a daily target that is a daily target numerical value. FIG. 11 is a graph showing the relationship between the date and the accumulated power consumption together with the monthly target that is a monthly target numerical value.

  The graph shown in FIG. 10 shows that the occupant suddenly consumes electric power when he / she gets up and starts working, and the electric power consumption decreases as the resident goes out to work, for example. ing. The graph shown in FIG. 11 shows that the power consumption slightly increases or decreases depending on the climate of the day, but increases at a substantially constant consumption.

  By displaying such graphs on the display units 14 and 15, it is possible to confirm whether or not the power is being used excessively at the present time. In addition, it is possible to predict how much consumption should be used in the remaining days and time. In this way, by presenting a target for each section and the residents of each section execute power saving to achieve the target, the apartment house 100 can be within the set target power consumption. As described above, the power consumption can be managed.

  The information providing device 17 can provide a message (word) as a notification for the consumption target, in addition to providing the daily goal or the monthly goal. In order to set the message, the information providing apparatus 17 can further include a notification selection unit 34 and a notification storage unit 35 that stores the notification content, as shown in FIG. The functional configuration illustrated in FIG. 12 is the same as the functional configuration illustrated in FIG. 3 except for the notification selection unit 34 and the notification storage unit 35, and thus description of similar functional units is omitted.

  The notification selection unit 34 stores, in the notification storage unit 35, a message to be transmitted for each category based on the history information for each category stored in the information storage unit 30 and the consumption target determined by the target determination unit 31. Select from messages. The notification storage unit 35 stores a plurality of messages according to the power consumption status for the notification selection unit 34 to select. The information providing unit 32 presents the content of the message by transmitting the message selected by the notification selecting unit 34 to the display units 14 and 15 of each section and displaying the message.

  FIG. 13 is a diagram illustrating the content of a message displayed on the display unit when the accumulated power consumption in a certain category exceeds the daily target numerical value, as an example of the message. The notification storage unit 35 stores a message and a selection condition serving as a reference for selecting the message in association with each other. For this reason, the notification selection unit 34 can determine which selection condition is satisfied from the history information and the determined consumption target, and can select a message associated with the satisfied selection condition. .

  The contents of the message are “I will soon exceed my goal. I will try to save.”, “I have exceeded my goal. I will do my best tomorrow (next month).” Let ’s do our best tomorrow (next month). ” These contents are examples, and are not limited to these.

  Selection conditions include: when the cumulative resource consumption exceeds 80% of the target value, when the cumulative resource consumption exceeds the target value, or when the cumulative resource consumption for the day (month) does not exceed the target value can do. These selection conditions can be stored in the notification storage unit 35 in association with the content of the message.

  Therefore, in the history information, if the power consumption exceeds 80% of the target value, but does not exceed the target value, the condition that the accumulated resource consumption above 80% of the target value is satisfied. Can be determined. For this reason, it is possible to select the message “Your goal will be exceeded soon. Let's try to save.” Associated with this condition.

  In the history information, when the target numerical value is exceeded, it can be determined that the condition that the accumulated resource consumption amount exceeds the target numerical value is satisfied. Therefore, it is possible to select the above-mentioned message “You have exceeded your goal. Let's do our best tomorrow (next month)” associated with this condition. When sending or displaying a message, if the message is related to daily, the content can be “tomorrow”, and if it is related to monthly, the content can be “next month”.

  In the history information, when the day (the month) is finished without exceeding the target numerical value, it is determined that the condition that the accumulated resource consumption on the day (month) does not exceed the target numerical value is satisfied. be able to. For this reason, the above-mentioned message “I cleared the goal. Let's do our best tomorrow (next month)” can be selected.

  When the notification selection unit 34 selects a message and the information providing unit 32 transmits and provides the message, in the case of a monthly target value, the start of the day, that is, midnight of the day is set. be able to. In the case of a daily target numerical value, it can be set at the start of each time, that is, 0:00, 0:00, etc.

  As explained above, the resource management system and the information providing device 17 are provided, and the target consumption is determined by using the resource consumption for each division of the apartment house, thereby reflecting the regional characteristics where the apartment house is located. More appropriate consumption targets can be presented. Regional characteristics include proximity to commercial facilities, weather characteristics, resource charge settings, and the like. This is because both of these affect resource consumption. In addition, the resource consumption of each category can be stored as history information for all categories, and the target consumption can be determined using the history information. Therefore, more appropriate consumption targets based on general trends in apartment buildings can be set. Can be set. Further, by using recent history information for each apartment group, it is possible to set a more appropriate consumption target that can cope with abnormal weather.

  In addition, by using the attribute information of the apartment house classification, it is possible to set a more appropriate consumption target that reflects the attribute. Also, by presenting the cumulative consumption of resources, the residents of the category can refer to the comparison results between the resource consumption of the category at that time and the target consumption, and they can control the resource consumption more appropriately. It can be carried out. In addition, it is possible to control resource consumption more appropriately by presenting recommended future correspondence contents as a message.

  In order to determine a resource consumption target and provide the target, the resource management system includes a plurality of measuring units that measure the resource consumption. When storing information other than resource consumption, determining a target from the stored information, and developing a service device that provides the target, the configuration other than the measurement unit can adopt the same configuration. It is also possible to reduce development costs.

  The present invention has been described with the above-described embodiments as a resource management system and an information providing apparatus. However, the present invention is not limited to the above-described embodiments, and other embodiments, additions, modifications, deletions, and the like can be modified within a range that can be conceived by those skilled in the art. . In addition, any aspect is included in the scope of the present invention as long as the operations and effects of the present invention are exhibited.
