(Embodiment 1)
A management support system according to this embodiment is shown in FIG. This management support system is a system for providing a power management support service by an electric power company. The power management support service is a service that calculates the predicted electricity usage for this month, the estimated monthly electricity bill, etc., graphs the usage status, and provides these as usage status information to customers who are consumers of electricity. . The management support system in FIG. 1 includes a communication control device 11, a support server 12, a database (DB) server 13 and a business terminal 14 installed in an electric power company, a communication control device 21 installed in a customer's house, and a measurement unit. 22 and a personal computer (PC) 23. The electric power company and the customer's home are in a state where data can be transmitted and received via the communication network NW.

Although there are many customers of the electric power company, the customer in FIG. 1 will be described as a representative example below. The customer's home is supplied with power from the distribution line 101 of the power company. That is, the electricity from the distribution line 101 is branched by the distribution board 112 through the watt hour meter 111 installed in the customer's house. As shown in FIG. 2, the distribution board 112 includes an overcurrent breaker 112A that detects and interrupts an overcurrent, a branch circuit 112B for branching electricity, and each distribution line through which a current branched by the branch circuit 112B flows. There are provided earth leakage breakers 112C _{1 to} 112C _n for detecting and interrupting the earth leakage. The electricity branched by the distribution board 112 is supplied to a television (TV) 121, a refrigerator 122,..., IH (Induction Heating) 123, etc., through an outlet (not shown) installed in the customer's house. IH123 is a cooking utensil using induction overheating.

  The communication control device 21 installed at the customer's home is like a router and enables data communication via the communication network NW. That is, the communication control device 21 receives data from a local area network (hereinafter referred to as “home LAN”) 21A, that is, recording data from the measurement unit 22 and data from the personal computer 23, from the communication network NW. The data is transmitted to the electric power company via, and the data from the electric power company is transmitted to the personal computer 23. The personal computer 23 is operated by a customer at the customer's house and is also used when receiving a power management support service.

The measurement unit 22 is a device that records the amount of electricity used in the customer premises. As shown in FIG. 2, the measurement unit 22 includes current sensors 22 _{1 to} 22 _n installed on the distribution board 112. The current sensors 22 _{1 to} 22 _n measure the current that flows through the branch circuit 112B of the distribution board 112 and sends the measurement results to the measurement unit 22, respectively.

When the measurement unit 22 receives the measurement results from the current sensors 22 _{1 to} 22 _n , the measurement unit 22 records data representing the amount of electricity used for a predetermined interval, for example, 10 minutes for each electric device. Moreover, the measurement unit 22 totals the electricity usage data recorded at regular intervals for each electric appliance, and records the daily electricity usage at the customer's home. Further, the measurement unit 22 uses the recorded electricity usage amount and the customer contract number as record data, and uses the record data at a predetermined interval, for example, once a day, at the customer's home LAN 21A and the communication control device 21. And to the electric power company via the communication network NW, the communication control device 11 and a local area network 11A in the company described later. In the following description, the home LAN 21A and the communication control device 21 at the customer's home through which data is transmitted and received, the communication network NW, the communication control device 11 of the electric power company, and the local area network 11A in the company described later are described. The description is omitted. These descriptions are also omitted when data is transmitted from the power company to the personal computer 23 at the customer's house.

  As with the communication control device 21, the communication control device 11 of the power company enables data communication via the communication network NW. In other words, the communication control device 11 transmits data from a local area network (hereinafter referred to as “in-house LAN”) 11A in the company, for example, data from the support server 12 to the customer's home via the communication network NW. In addition, the recording data from the customer's house is sent to the support server 12.

  The business terminal 14 is a computer dedicated to business that is operated by a person in charge of the power company. The business terminal 14 performs, for example, new registration of a power management support service to the support server 12 by the operation of the person in charge.

  The support server 12 and the database server 13 are used for providing a power management support service. The support server 12 is a dedicated computer for providing a power management support service to a customer. The support server 12 collects data required for the power management support service and stores it in the database server 13. The database server 13 is a dedicated computer for storing and managing data. The support server 12 uses the data stored in the database server 13 to calculate a predicted electricity usage amount, a predicted monthly electricity bill, and the like. For this purpose, the database server 13 stores the following various data.

  The data stored in the database server 13 includes a customer registration table. The customer registration table records customers who receive the power management support service, an example of which is shown in FIG. In the customer registration table of FIG. 3, as the identification information for identifying the customer who applied for the service use, the “contract number” when the customer contracts with the electric power company, the “name” and “e-mail address” of this customer. Is recorded. The e-mail address is used when an electric power company sends usage information such as a predicted electricity usage amount and a predicted monthly electricity fee to the customer by e-mail. Furthermore, in the customer registration table, “user ID” and “password” for ensuring security when the customer receives the power management support service using the personal computer 23 are recorded. The user ID (IDentification) and the password are for confirming the identity of the customer when the support server 12 provides the power management support service to the customer. In addition to this, the customer registration table records “start date” for starting the power management support service.

  The data stored in the database server 13 includes a contract table. The contract table records the contents of the contract made by the customer with the electric power company, and an example thereof is shown in FIG. In the contract table of FIG. 4, “contract number” when the customer contracts with the electric power company, and “monthly meter reading date” for measuring the electricity usage amount of the customer are recorded. In the contract table, “setting fee” set by the customer is recorded. The set charge is a monthly electricity charge targeted by the customer. Further, in the contract table, when a customer uses a device to be discounted, this device is recorded as “discount”. For example, “microcomputer type” indicates that the customer is using a device energization control type (microcomputer type) regenerative electric heater that is a discount target. In addition, the “contract type” used for calculating the electricity bill is recorded in the contract table. The contract type represents the type of electricity contract, such as metered light A or metered light B.

  The data stored in the database server 13 includes a usage table. The usage amount table records the power used by the customer every day, and an example thereof is shown in FIG. The usage amount table of FIG. 5 is created for each customer, and FIG. 5 shows an example of a customer whose contract number is “9801”. In the following description, the contract number “9801” will be described as the customer shown in FIG. In the usage amount table of FIG. 5, each electric usage amount is recorded in order from day to day. The electricity consumption recorded in this way can be recorded for several years.

  The support server 12 is a dedicated computer that performs a power management support service. Each time the support server 12 receives the record data of the previous day from the measurement unit 22 at the customer's house, the support server 12 records the amount of electricity used represented by the received data in the database server 13. At this time, the support server 12 records the amount of electricity used in the usage table (FIG. 5) corresponding to the contract number.

  When the support server 12 receives an instruction to use the power management support service from the personal computer 23 at the customer's home, the support server 12 starts power management support processing. An example of this power management support process is shown in FIGS. When the support server 12 starts the power management support process of FIG. 6, the support server 12 displays an input screen on the personal computer 23 that has issued a service use instruction (step S <b> 1). The input screen is a screen for a customer to input a user ID and a password. After step S1, when the support server 12 receives the user ID and password from the personal computer 23 (step S2), the registration contents registered in the customer registration table (FIG. 3), the user ID received in step S3, and The password is compared (step S3). If the support server 12 determines that the two match as a result of the comparison (step S4), the support server 12 checks the contract number corresponding to the user ID and password from the registered content of the customer registration table (FIG. 3) (step S5). Thereafter, the support server 12 refers to the usage table (FIG. 5) corresponding to the contract number checked in step S5, and checks the number of recording days in which the amount of electricity used is recorded (step S6). It is determined whether it is within a day (step S7). The 15th day, which is the criterion for determining the number of recording days, is a value arbitrarily set by the business terminal 14. If it is determined that the number of recording days is within 15 days, the support server 12 performs a first calculation process (step S8).

  An example of the first calculation process is shown in FIG. When the support server 12 starts the first calculation process, the usage server (FIG. 5) is referred to read the daily electricity usage up to the previous day (step S41), and the daily usage is added to the previous day. The amount of electricity used up to is calculated (step S42). The amount of electricity used calculated in step S42 is the actual value up to the previous day, and is the amount of electricity used most recently for the day. When step S42 ends, the support server 12 calculates an average value of the amount of electricity used per day from the amount of electricity used (actual value) up to the previous day calculated in step S42 and the number of days for which the amount of electricity used is calculated. (Step S43).

For example, as shown in FIG. 9, when the customer's meter reading date is the 25th of every month, when the power management support service starts on the 28th, the electricity usage from the 27th is recorded in the database server 13 respectively. Is done. If the customer inputs a service usage instruction to the personal computer 23 on the 30th day of the current month, the support server 12 adds the electricity usage amount for the 27th to 29th days most recently on the 30th day to the previous day, that is, the 29th day. The amount of electricity used is calculated. Thereafter, the support server 12 divides the calculated electricity usage by three days, 27th, 28th, and 29th, and calculates an average value of the electricity usage per day. In this way, when step S43 is completed, the support server 12 checks the number of days remaining from the day following the previous meter reading date to the next meter reading date, that is, the remaining meter reading period (step S44). In the case of FIG. 9 described above, the support server 12 examines the remaining number of days in the meter-reading period, with the remaining days checked in step S44 being January 26 and January 30 to February 25. When step S44 ends, the support server 12 calculates the amount of electricity used for the remaining days of the meter reading period from the average value of the electricity usage and the remaining days.
(Average electricity usage) x (remaining days)
(Step S45). The electricity usage calculated in step S45 is a predicted value calculated using the latest average value. When step S45 ends, the support server 12 adds the actual value calculated in step S42 and the predicted value calculated in step S45 to calculate an added value (step S46). Thereby, the amount of electricity predicted to be used during the meter reading period, that is, the predicted amount of electricity used is calculated.

When step S46 ends, the support server 12 refers to the contract table (FIG. 4), and checks the discount from the contract contents (step S47). Thereafter, the support server 12 calculates each electricity rate by applying the discount checked in step S47 (step S48). In step S48, the support server 12 calculates the electricity charge corresponding to the amount of electricity used up to the previous day calculated in step S42 by applying a discount. The electricity bill calculated at this time is
Basic charge (including discount) + actual electricity charge. This electricity charge is the actual electricity charge. In step S48, the support server 12 calculates the electricity rate corresponding to the addition value of the actual value and the predicted value calculated in step S46 by applying a discount. The electricity bill calculated at this time is
Basic charge (including discount) + actual value of electricity charge + predicted value of electricity charge. This electricity charge is the estimated monthly electricity charge. When step S48 ends, the support server 12 ends the first calculation process.

  When the first calculation process ends, the support server 12 checks the set fee with reference to the contract table (FIG. 4) (step S9). Thereafter, the support server 12 compares the actual electricity price and the predicted monthly electricity charge calculated in the first calculation process with the set charge checked in step S9 (step S10). In step S10, the support server 12 calculates, for example, the difference between the set charge and the actual electricity charge, and calculates the difference between the set charge and the predicted monthly electricity charge. In addition, in step S10, there are various comparison methods. When step S10 is completed, the support server 12 transmits the calculated fee and the comparison result to the customer's personal computer 23 by e-mail as usage status information (step S11). In step S11, the support server 12 creates various graphs from the data in the usage table (FIG. 5) and adds them to the usage status information. Then, the support server 12 ends the power management support process when the transmission of the e-mail is completed in step S11 or when the user ID and the password do not match in step S4.

  On the other hand, when the support server 12 determines in step S7 that the number of recording days has passed, the second calculation process is performed (step S12). An example of the second calculation process is shown in FIG. When the support server 12 starts the second calculation process, the usage server (FIG. 5) is referred to read out the daily electricity usage up to the previous day (step S61), and the daily usage is added to the previous day. The amount of electricity used, that is, the actual value is calculated (step S62). When step S62 ends, the support server 12 collects the daily electricity usage read in step S61 for each day of the week (step S63). Further, the support server 12 calculates an added value of the electricity usage collected for each day of the week, and calculates an average value for each day of the week (step S64).

  For example, as shown in FIG. 10, when the meter reading date of the customer is 25th of every month, if the service use instruction is issued, that is, if that day is December 15, the support server 12 Using the electricity usage amount on December 14th, an additional value for each day of the week is calculated. Then, an average value for each day of the week is calculated using this added value. When step S64 ends, the support server 12 checks the remaining days of the meter reading period (step S65). In the case of FIG. 9 described above, the support server 12 sets December 15 to December 25 including the current day as the remaining days of the meter reading period. When step S65 ends, the remaining days examined are collected by day of the week (step S66).

  For example, when the meter reading period is the same as that in FIG. 10, if the current day is December 15, as shown in FIG. 11, the December 15 to December 25 examined in step S65 are collected by day of the week. Calculate the number of days for each day of the week.

When step S66 ends, the support server 12 calculates the electricity usage used for the remaining days of the meter reading period from the average value for each day of the week and the remaining days for each day of the week.
(Average value of electricity usage on Monday) x (Number of remaining days on Monday)
+ (Average value of electricity usage on Tuesday) x (Remaining days on Tuesday)
+ (Wednesday electricity usage average) x (Wednesday remaining days)
+ (Average value of electricity usage on Thursday) x (Number of remaining days on Thursday)
+ (Average value of electricity usage on Friday) x (Number of remaining days on Friday)
+ (Average value of electricity usage on Saturday) x (Number of remaining days on Saturday)
+ (Average value of electricity usage on Sunday) x (Number of remaining days on Sunday)
(Step S67). The amount of electricity used calculated in step S67 is a predicted value calculated using the average value of the amount of electricity used by day of the week. When step S67 ends, the support server 12 calculates an addition value of the actual value calculated in step S62 and the predicted value calculated in step S67 (step S68). Thereby, the amount of electricity predicted to be used during the meter reading period, that is, the predicted amount of electricity used is calculated.

When step S68 ends, the support server 12 refers to the contract table (FIG. 4) and checks the discount from the contract contents (step S69). Thereafter, the support server 12 calculates each electricity rate by applying the discount determined in step S69 (step S70). In step S70, the support server 12 calculates the electricity rate corresponding to the amount of electricity used up to the previous day calculated in step S62 by applying a discount. The electricity bill calculated at this time is
Basic charge (including discount) + actual electricity charge. This electricity charge is the actual electricity charge. Further, in step S70, the support server 12 calculates the electricity rate corresponding to the addition value of the actual value and the predicted value calculated in step S68 by applying a discount. The electricity bill calculated at this time is
Basic charge (including discount) + actual value of electricity charge + predicted value of electricity charge. This electricity charge is the estimated monthly electricity charge. When step S70 ends, the support server 12 ends the second calculation process.

  When the second calculation process of step S12 ends, the support server 12 performs the processes of steps S9 to S11, and ends the power management support process.

  Next, a management support method using the management support system of this embodiment will be described. When the customer applies for the use of the power management support service to the power company, the person in charge of the power company operates the business terminal 14, registers the customer in the customer registration table (FIG. 3) of the database server 13, and applies for the customer. Accept. Thereafter, when the power management support service is started, the measurement unit 22 at the customer's home transmits the electricity usage of the previous day to the power company once a day. When receiving the electricity usage amount from the customer, the power company support server 12 records the electricity usage amount in the usage table (FIG. 5) of the database server 13.

  In such a state, when the customer operates the personal computer 23 to instruct use of the power management support service and inputs a user ID and password, the power company support server 12 uses the received user ID and password as the customer. The registration table (FIG. 3) is collated, and if these are appropriate, power management support processing is performed. At this time, if it is within 15 days since the customer applied for the service, the support server 12 calculates the actual and estimated monthly electricity charges calculated based on the first calculation process, and these charges and the set charges. The comparison result and the graph are transmitted to the customer's personal computer 23 as usage status information. In addition, when 15 days have passed since the customer applied for the service, the support server 12 calculates the actual and estimated monthly electricity charges calculated based on the second calculation process, and these charges and the set charges. The comparison result and the graph are transmitted to the customer's personal computer 23 as usage status information.

  When the customer's personal computer 23 receives the usage status information from the power company, the customer's personal computer 23 displays and outputs the actual electricity price represented by the usage status information, the predicted monthly electricity price, and the comparison result between these charges and the set price. To do. In this way, the customer manages the electricity bill for the current month. For example, when there is still a number of days until the next meter reading date, but the estimated monthly electricity charge is close to the set charge, the use of the electric equipment is refrained. Manage electricity charges such as refraining from using electrical equipment that uses a lot of electricity.

  Thus, according to this embodiment, the actual electricity charge up to the current day, the predicted monthly electricity charge for the current month, and the comparison result between these charges and the set charge are provided to the customer as usage status information. It is possible to support the management of electricity charges and electricity usage. Further, if the date when the instruction to use the power management support service is input to the personal computer 23 is within 15 days from the start date of this service, the predicted monthly electricity charge is calculated using the latest average electricity usage. . As a result, immediately after the customer applies for the service, the support server 12 can provide the customer with a comparison result between the predicted monthly electricity charge and the set charge. Furthermore, since the average amount of electricity used by day of the week is used after 15 days from the start date of the service, the electricity usage according to the lifestyle pattern of the customer's day of the week is reflected, and a highly accurate predicted monthly electricity charge In addition, the support server 12 can provide the set fee and the comparison result to the customer.

(Embodiment 2)
In the first embodiment, every time the previous day's recording data is received from the measurement unit 22 at the customer's house, the support server 12 records the electricity usage amount represented by the received data in the database server 13. On the other hand, in this embodiment, the recording data for the previous day is received from the measurement unit 22 at the customer's house. This recorded data records the amount of electricity used for each electrical device used at the customer's home, and records the amount of electricity used every short time. An example of the recording data is shown in FIG. In the recorded data of FIG. 12, electricity used on the previous day in the television 121, refrigerator 122,..., IH123 is recorded every 10 minutes.

  The support server 12 aggregates the previous day's recorded data stored in the database server 13 and creates a usage table (FIG. 5). Thereafter, in step S10 of the power management support process, the support server 12 uses the recorded data (FIG. 12) to visualize the electricity usage by the television 121, the refrigerator 122,. Add graphs to usage information.

  Thus, according to this embodiment, since the support server 12 visualizes and sends the amount of electricity used for each electrical device used in the customer's home to the customer, the customer can manage the amount of electricity used when It is possible to visually grasp which device uses a lot of electricity.

(Embodiment 3)
In the first embodiment and the second embodiment, the support server 12 is used by using the customer registration table (FIG. 3), the contract table (FIG. 4), and the usage table (FIG. 5) stored in the database server 13 of the electric power company. Performed the power management support processing, but in this embodiment, the following is performed. That is, the personal computer 23 at the customer's home stores items corresponding to this customer from the contents of the contract table (FIG. 4), and also stores a use table (FIG. 13). In this embodiment, the personal computer 23 receives data representing the amount of electricity used from the measurement unit 22. Then, the personal computer 23 records the daily electricity usage in the usage table (FIG. 5).

  In this state, when the customer operates the personal computer 23 to activate the power management support service, the personal computer 23 performs power management support processing. At this time, since the customer uses the personal computer 23 at home, the processes of steps S1 to S3 performed in the power management support process of the first embodiment are omitted. When the personal computer 23 performs the power management support process, the personal computer 23 obtains the actual electricity charge, the predicted monthly electricity charge, the comparison result between these charges and the set charge, and outputs these.

  Thus, according to this embodiment, it is possible to manage the amount of electricity used and the electricity bill using the personal computer 23 at home. Further, the use of the communication network NW is not required for these managements. In other words, even customers who do not use the communication network NW can manage the amount of electricity used and the electricity charge.

  As mentioned above, although each embodiment of this invention has been described in detail, the specific configuration is not limited to each embodiment, and even if there is a design change or the like without departing from the gist of this invention, It is included in this invention. For example, using each usage table (FIG. 5), the ranking result of the customer receiving the power management support service may be provided as information indicating the usage status. In addition, when the database server 13 receives and stores the amount of electricity used for each electrical device from the measurement unit 22 at the customer's home, the replacement status of the electrical device is determined based on the amount of electricity used for each electrical device as the usage status. You may be advised. Moreover, you may make it advise the achievement level etc. of the energy saving currently performed at the customer's house based on the electric usage amount for every electric equipment as a use condition. Further, based on the amount of electricity used for each electrical device as the usage status, the situation of a person living alone may be monitored, and the monitoring result and the like may be communicated to a distant party. Further, based on the amount of electricity used for each electrical device as the usage status, the customer's house may be monitored, and the monitor result may be communicated to the householder as security information. In each embodiment, the supply is electricity. However, in addition to electricity, the amount of use such as water supply can be added to the present invention as a use situation. Furthermore, information on the amount of carbon dioxide emission may be provided to the customer corresponding to the amount of electricity used.
