Description

[Technical field]

[0001] The present invention relates to an information providing system for providing information on electricity usage, such as electricity usage amount and electricity bill. [Background technology]

[0002] Currently, conventional mechanical watt-hour meters (mechanical meters) or electronic watt-hour meters (electronic meters) are being gradually replaced by smart meters. Smart meters are equipped with communication functions and can measure and store the amount of power used (electricity used) every 30 minutes, so many services that utilize these functions have been proposed.

[0003] For example, a power data processing system has been proposed that estimates a user's activity state using the amount of power measured by a smart meter. In this power data processing system, power amount attribute data is added to the power data, and the relationship between this and the user's activity state is learned by machine learning, thereby estimating the user's activity state (see, for example, Patent Document 1).

[0004] There is an energy diagnostic system that provides information about the energy desired by a consumer in response to the consumer's request to understand his or her own energy usage or to determine a rate plan for each energy source that is suitable for the consumer (see, for example, Patent Document 2).

[0005] Furthermore, in order to increase the interest of consumers in their electricity usage and in electric power companies, an electricity rate discount system and method have been proposed that provides consumers with a discount on their electricity usage charges for a specified period of time (see, for example, Patent Document 3). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2020-28208 A [Patent Document 2] JP 2016-66363 A [Patent Document 3] JP 2020-201838 A Summary of the Invention [Problem to be solved by the invention]

[0007] Consumers may have mistrust for their electricity usage, solar power generation, etc., and may make inquiries about this to power suppliers (electricity businesses). For such inquiries, it is important to provide information in a timely manner, and smart meter power usage every 30 minutes (30-minute value) can be used. For such inquiries accompanied by mistrust, it is preferable to provide information that is easy to see and understand, but the 30-minute value on a smart meter is just a list of numbers, which is not easy to see or understand.

[0008] In addition to inquiries about electricity usage and solar power generation, consumers also make inquiries about electricity bills, rate plans, rate discounts, points given for electricity usage, etc. On the other hand, in order to increase consumers' interest in electricity, electric power companies sometimes provide consumers with information that is useful to them, and it is expected that the provision of information about electricity usage will increase in the future.

[0009] An object of the present invention is to provide an information providing system capable of providing useful information on electricity usage, such as electricity usage amount and electricity charges, to consumers in a timely manner. [Means for solving the problem]

[0016] Fig. 1 is a configuration diagram of an information providing system 1 according to a first embodiment of the present invention. Fig. 2 shows a menu list 21 provided by a web server 20 of the information providing system 1 according to the first embodiment of the present invention. Fig. 3 is a functional configuration diagram of an information management server 40 of the information providing system 1 according to the first embodiment of the present invention.

[0017] The information provision system 1 of the first embodiment of the present invention is an information provision system that provides information related to electricity usage such as electricity usage and electricity bills, and includes a meter data management server 10 that stores power usage (electricity usage) data of consumers (customers) transmitted from smart meters, a web server 20 that provides a website, and an information management server 40 that creates or provides materials related to electricity usage such as electricity usage and electricity bills.

[0018] A smart meter is an electricity meter equipped with a communication function that measures the power usage of a consumer and stores the power usage for 30 minutes as 30-minute value data. This 30-minute value data is linked to a smart meter identification number (meter number) and is transmitted to the meter data management server 10 via an aggregation device, a wireless base station, a communication system (HES), etc.

[0019] The meter data management server 10 includes a communication means for transmitting and receiving data, a storage means for storing data, and a control means for controlling the communication means and the storage means, and stores the 30-minute value data for each date and time of use transmitted from each smart meter in the storage means.The meter data management server 10 also transmits the 30-minute value data to be stored in response to a request from the information management server 40.

[0020] The web server 20 is a computer equipped with a CPU, memory, storage means, input / output interface, and input / output means, and provides the website of an electric power company (electric utility). The web server 20 also connects to an information management server 40 via a network 100, and requests the information management server 40 to create and provide information corresponding to a menu requested via the electric power company's website.

[0021] The electric power company's website has a site exclusively for web members, and provides information on electricity usage such as electricity usage and electricity charges through this site exclusively for web members. Specifically, the site exclusively for web members has a login screen for web members to log in, an input screen for inputting an ID and password, and a menu list screen from which menus can be selected, and provides the login screen, etc. to the consumer terminal (customer terminal) 200 that accesses the site.

[0022] Here, the web member is a customer (consumer) of the electric power company who has registered as a member in advance. The customer terminal 200 is a terminal managed and used by the customer, such as a personal computer or a mobile terminal (smartphone).

[0023] The menu list 21 provided to the consumer terminal 200 is composed of electricity usage, "electricity usage message" 26, and "price plan" 27, as shown in Fig. 2, and the power usage is composed of "electricity usage record" 22, "comparison with past usage record" 23, "comparison with local electricity usage" 24, and "relationship between environment and electricity usage" 25, providing information on electricity usage such as electricity usage and electricity charges. These menus are configured so that not only one menu but all menus can be selected at once.

[0024] "Record of electricity usage" 22 provides the electricity usage record of the consumer, and by specifying the year and month, the record of electricity usage for that month is displayed. "Comparison with past usage record" 23 provides a comparison table of the electricity usage for the month specified by the consumer with the electricity usage for that month in the previous year. At this time, it is a good idea to display the temperature difference and the hours of sunshine together with the comparison table. The hours of sunshine can also be expressed as the monthly ratio of sunny, cloudy, rainy, snowy, etc. Any suspiciousness regarding the consumer's electricity usage (electricity bill) or solar power generation can be resolved by using this "Record of electricity usage" 22 or "Comparison with past usage record" 23.

[0025] "Comparison with local electricity usage"24 provides a comparison of the electricity usage of the consumer with that of the consumer's neighboring area. The 30-minute value data is collected by area, for example, by area code such as postal code, or by apartment complexes with a certain number of rooms or more, and the average value including user data and the fluctuation range over time are used as "area coefficients" to ensure anonymity and are used as big data. By comparing the average value for any area that reflects the layout, load equipment, and use classification (residential, commercial, industrial, etc.) of the apartment complex with the consumer's electricity usage, it becomes possible to propose more accurate rate plans and give advice to solve problems.

[0026] "Relationship between the environment and electricity usage" 25 provides data showing the relationship between the environment and electricity usage. It extracts locations with little fluctuation in usage, such as contracts where people are likely to be absent for long periods of time and there is no use of electrical appliances, by specifying arbitrary conditions, and uses the fluctuation in usage as the "environmental coefficient." It defines the fluctuation in usage as the change in outside temperature in the area, and if the calculated "environmental coefficient" is higher than the average, it displays that usage tends to be higher than in other areas.

[0027] The "electricity usage message" 26 provides information for making good use of electricity. Specifically, it provides information on home appliances, their power consumption, and how to use them well. For example, it provides a list of temperature settings, deterioration over time, and other information on representative home appliances, divided into summer and winter. As another method, it is also possible to provide a list of home appliances configured so that home appliances can be selected, and provide information on how to use the selected home appliances well.

[0028] "Price Plan" 27 provides a fee trial calculation service that is tailored to the consumer's actual situation. After setting a fee unit price different from the one currently used by the consumer, the amount of usage for any period is saved as "new actual results" and a fee trial calculation service that is tailored to the consumer's actual situation is provided. Fee trial calculations are performed based on, for example, actual usage over the past year and assumed monthly usage (profiling) based on a uniform coefficient.

[0029] The web server 20 also includes a consumer database 30. The consumer database stores contract numbers, contract holder names, contract types, addresses, telephone numbers, facsimile numbers, email addresses, etc. The contract numbers are linked to smart meter identification numbers (meter numbers). In this embodiment, the consumer database 30 is provided within the web server 20, but a separate data server connected to the network 100 may also be provided to store consumer data therein.

[0030] The information management server 40 is a computer equipped with a CPU, memory, storage means, input / output interface, and input / output means, and has programs for causing the computer to function as the following means, and automatically creates information regarding electricity usage, such as electricity usage and electricity charges, in a predetermined procedure in response to a request from the web server 20.

[0031] The information management server 40 is provided with, as means for creating materials relating to electricity usage such as electricity usage and electricity charges, actual result data creation means 41 for creating materials relating to electricity usage, comparison data creation means 42 for creating materials comparing the electricity usage for a specified month with the electricity usage for that month in the previous year, regional result data creation means 43 for creating materials comparing the electricity usage records of a consumer with the electricity usage records of the region, environmental impact data creation means 44 for creating materials showing the relationship between the environment and electricity usage, and fee estimate data creation means 45 for calculating fees in accordance with the actual situation of the consumer and creating materials relating thereto.

[0032] The information management server 40 also includes a material / template providing means 46 that stores materials such as electricity utilization messages for making good use of electricity and templates such as delivery instructions for sending various materials, and provides materials in response to requests from the web server 20. The material / template providing means 46 also includes templates for creating materials on actual electricity usage, etc. Each means of the information management server 40 creates and provides materials corresponding to the menu list of the web server 20.

[0033] The result data creation means 41 is a means for creating a document when "Electricity usage record" 22 is selected from the menu list of the web server 20. The result data creation means 41 specifies the meter number and the year and month linked to the contract number for the consumer information and the requested year and month of electricity usage sent from the web server 20, and acquires the corresponding 30-minute value data from the meter data management server 10. Additionally, the result data creation means 41 reads out a template used to create a result table of electricity usage from the document / template providing means 46, and creates a result table of electricity usage by inputting data into the template.

[0034] Figures 4 and 5 show the electricity usage record table created by the information management server 40. Here, it is divided into Figures 4 and 5, but in reality it is a single A3-sized vertical document with Figure 4 oriented vertically and Figure 5 oriented vertically below it. The record table lists the relevant year and month of the record table at the top, followed by the contract number and contract name, and below that is a data table for the relevant month. This data table lists the hourly electricity usage for each day and the daily usage, and time periods that exceed twice the average electricity usage are displayed in yellow, and time periods that exceed four times the average electricity usage are displayed in red.

[0035] Below the data table is a bar graph showing the amount of electricity usage per day, and below that is a bar graph showing the amount of electricity usage by time of day. The bottom row is a 3D bar graph showing the electricity usage. This is accompanied by supplementary explanations such as "About usage trends" which explains the average usage per hour and other trends in electricity usage, "About power consumption" which shows the power consumption of major home appliances, and "For smart use of electricity" which provides advice on how to use electricity smartly.

[0036] The format of the electricity usage record is not limited to the above format, but if the electricity usage record is in the above format, it is preferable because the printed paper can be folded in the middle to make a comparison between the 30-minute value data in the upper half of the paper and the 3D graph in the lower half. Also, a record in the above format makes it easy to visualize monthly usage.

[0037] The comparison data creation means 42 is a means for creating data when "Comparison with past usage records" 23 is selected from the menu list 21 of the web server 20. The comparison data creation means 42 specifies the meter number and year and month linked to the contract number for the consumer information and electricity usage amount for the requested year and month sent from the web server 20, and acquires 30-minute value data for the relevant month and the relevant month of the previous year from the meter data management server 10. Additionally, the comparison data creation means 42 reads out a template used for creating a "comparison table with past usage records" from the data and template providing means 46, and creates a comparison table with past usage records by inputting data into the template.

[0038] When creating the "comparison table with past usage records," the comparison data creation means 42 preferably also displays supplementary information using temperature differences and hours of sunshine, etc., in comparison with past years. Meteorological data such as temperature and hours of sunshine may be made from commercially available data published by the Japan Meteorological Agency.

[0039] The regional performance data creation means 43 is a means for creating data when “Comparison with regional electricity usage” 24 is selected from the menu list 21 of the web server 20. The regional performance data creation means 43 identifies the neighboring addresses of the consumers from the consumer information transmitted from the web server 20, accesses the web server 20, and reads out the consumer information of the neighboring addresses from the consumer database 30.

[0040] Thereafter, the regional performance data creation means 43 designates the meter number and year and month linked to the contract number of the consumer and consumers at neighboring addresses, and acquires the corresponding 30-minute value data from the meter data management server 10. The regional performance data creation means 43 adds up the acquired 30-minute value data of consumers at neighboring addresses, divides this by the number of contracts, and calculates the regional electricity usage record. Next, the template used to create a "regional performance comparison table" is read from the document / template providing means 46, and the regional performance comparison table is created by inputting data into the template.

[0041] The environmental impact document creation means 44 is a means for creating documents when "Relationship between the environment and electricity usage" 25 is selected from the menu list 21 of the web server 20. When the environmental impact document creation means 44 receives a command to create "Relationship between the environment and electricity usage" from the web server 20, it extracts, by specifying arbitrary conditions, contracts for locations with little fluctuation in usage, such as contracts where people are likely to be absent for long periods of time and there is no use of home appliances, and obtains the corresponding 30-minute value data from the meter data management server 10. Next, it reads out a template used to create the "environmental impact document" from the document / template providing means 46, and creates environmental impact documents by inputting data into the template.

[0042] Here, fluctuations in usage are used as an "environmental coefficient," and fluctuations in usage are defined as changes in the outside temperature in the region. If the calculated "environmental coefficient" is greater than the average, it shows that usage tends to be higher in that region than in other regions.

[0043] The fee trial calculation material creation means 45 is a means for performing trial calculations of fees based on the actual circumstances of the consumer and creating related materials. When the fee trial calculation material creation means 45 receives a command to create the "fee plan" 27 from the web server 20, it specifies the meter number from the consumer information sent from the web server 20 and obtains 30-minute value data for the past year from the meter data management server 10. It sets a new fee unit price based on this usage record and performs a fee trial calculation with the usage amount for an arbitrary period as the "new record." The fee trial calculation material creation means 45 reads a template used to create the "fee trial calculation material" from the material / template providing means 46 and creates fee trial calculation materials by inputting data into the template.

[0044] When the information management server 40 receives a command to provide the "Electricity Use Message" 26 from the web server 20, it reads out the "Electricity Use Message" materials from the material / template providing means 46 and transmits them to the web server 20. If the "Electricity Use Message" 26 materials are created separately for summer and winter, or if materials are created for each home appliance, it reads out the requested materials from the material / template providing means 46 and transmits them to the web server 20. An example of the "Electricity Use Message" materials is shown in FIG. 6.

[0045] Next, a procedure for providing information by the information providing system 1 according to the first embodiment of the present invention will be described with reference to FIG.

[0046] A consumer who is a member of the electric power company's website accesses a web member-only site set up by the electric power company through a consumer terminal 200 (step S1). The web server 20 provides the consumer terminal 200 with a screen (login screen) for logging in to the web member-only site (step S2). The consumer inputs an ID and a password to log in to the web member-only site (step S3).

[0047] The web server 20 provides the customer terminal 200 with a screen of the menu list 21 (step S4), and the customer selects one or more menus from the menu list 21 (step S5). Here, it is assumed that "Record of electricity usage" 22 has been selected. When "Record of electricity usage" 22 is selected, the web server 20 provides a screen for inputting the year and month of the "Record of electricity usage" 22 (step S6), and the customer inputs the year and month of the requested "Record of electricity usage" 22 from the screen (step S7).

[0048] When the year and month of the requested "electricity usage record" 22 is input, the web server 20 reads the consumer data from the consumer database 30 and transmits the consumer data together with the year and month of the requested "electricity usage record" 22 to the information management server 40 (step S8). When the information management server 40 receives the data from the web server 20, it specifies the meter number and year and month, and requests 30-minute value data from the meter data management server 10 (step S9). The meter data management server 10 reads the requested 30-minute value data from the storage means, and transmits it to the information management server 40 (step S10).

[0049] When the information management server 40 receives the 30-minute value data, it reads out a template for creating a performance table of electricity usage from the material / template providing means 46, inputs data into the template, creates a performance table of electricity usage, and transmits it to the web server 20 (step S11). When the web server 20 receives the performance table from the information management server 40, it provides the customer terminal 200 with a screen on which the performance table can be viewed (step S12).

[0050] As a result, a consumer who is a member of the electric power company's website can check the actual amount of electricity usage through the consumer terminal 200 (step S13). The information providing system 1 basically operates in the same manner for other menus in the menu list 21 provided by the web server 20.

[0051] As described above, the information providing system 1 of the first embodiment of the present invention provides information on electricity usage such as electricity usage and electricity charges that is useful to consumers through the electricity utility's website, so that web members can easily check the actual electricity usage amount through their own terminals. In addition, the information providing system 1 is convenient for consumers because it is configured to be able to provide multiple pieces of information on electricity usage such as electricity usage and electricity charges.

[0052] Furthermore, the information providing system 1 basically creates information on electricity usage, such as electricity usage and electricity charges, based on the actual electricity usage of the consumer who requested the information. This is preferable because it allows consumers to obtain practical information that is in line with the actual situation. This also helps to eliminate doubts about electricity usage, solar power generation, etc. Furthermore, the information providing system 1 of the first embodiment of the present invention can provide information using data on electricity usage and weather of consumers in neighboring areas, so consumers can obtain a variety of useful information.

[0053] In addition, the information providing system 1 of the first embodiment of the present invention automatically creates and transmits information (documents) regarding electricity usage, such as electricity usage and electricity charges, in accordance with a predetermined procedure, and therefore can provide information requested by consumers in a timely manner.

[0054] Fig. 8 is a configuration diagram of an information providing system 2 according to a second embodiment of the present invention. The same components as those in the information providing system 1 according to the first embodiment of the present invention shown in Figs. 1 to 7 are denoted by the same reference numerals and will not be described.

[0055] An information providing system 2 according to the second embodiment of the present invention has a configuration in which an operator terminal 50 is added to the information providing system 1 according to the first embodiment of the present invention. The operator terminal 50 is a computer connectable to the network 100 and managed by an operator who responds to inquiries by phone from consumers. The operator is usually a person in charge of an inquiry center established by an electric power company.

[0056] Consumers who have a contract with an electric power company and are members of the website provided by the electric power company (web members) can log in to a website for web members from their own terminal 200 and obtain information and data such as a performance table of electricity usage from the information provision system 1 of the first embodiment, as explained in the information provision system 1 of the first embodiment. Conversely, consumers who are not web members cannot obtain a performance table of electricity usage from the information provision system 1 of the first embodiment.

[0057] The information providing system 2 of the second embodiment is a system for allowing consumers other than web members to obtain information and data such as actual electricity usage, and an operator who responds to inquiries from consumers by phone hears the request from the consumer and logs in to a site exclusively for web members from an operator terminal 50. After that, the procedure for creating a table of actual electricity usage and the like is the same as that of the information providing system 1 of the first embodiment.

[0058] For consumers who make inquiries by phone, the requested information and data, such as a performance table of the electricity usage, must be printed out on paper and mailed. For this reason, in the information provision system 2 of the second embodiment, a delivery guide is created together with the requested information and data, such as a performance table of the electricity usage, and sent to the operator terminal 50 in the following manner.

[0059] When the web server 20 determines from the ID and password that the terminal logged in to the web member-only site is an operator terminal 50, it requests the information management server 40 to create and return a delivery guide in addition to an electricity usage record table, etc. In response to the request from the web server 20, the information management server 40 reads out a template for creating an electricity usage record table, etc., and a delivery guide template from the material / template providing means 46, and creates and returns a delivery guide together with the electricity usage record table, etc.

[0060] The operator uses the operator terminal 50 to print out the requested information and data, such as the actual electricity usage table, on paper and mails it to the customer. If the customer wishes to receive the materials by facsimile, they are sent by facsimile. The operator may also transfer the information and data, such as the actual electricity usage table, received through the operator terminal 50 to a responsible department, and the responsible department may mail or facsimile the materials to the customer. The responsible department may be, for example, an office of the electric power company that has jurisdiction over the customer's area.

[0061] As described above, according to the information providing system 2 of the second embodiment of the present invention, a consumer can apply for information on electricity usage such as electricity usage and electricity charges by telephone or facsimile to the electric power company's inquiry center, and receive the requested information by mail or facsimile. In this way, even consumers who are not members of the electric power company's web site can conveniently obtain information on electricity usage such as electricity usage and electricity charges.

[0062] The above describes the information provision system of the present invention using the information provision systems 1 and 2 of the first and second embodiments of the present invention. However, the information provision system of the present invention is not limited to the above embodiments and can be modified and used within the scope that does not change the gist of the invention.

[0063] The documents describing information on electricity usage such as electricity usage and electricity charges and their forms may be other than those of the above embodiment. For example, the electricity usage records shown in Fig. 4 and Fig. 5 show electricity usage in 1-hour units, but may show electricity usage in 2-hour units, 6-hour units, etc. On the other hand, it is preferable that the documents describing information on electricity usage such as electricity usage and electricity charges have a visually appealing structure such as graphs and colors so that the content can be understood at a glance, as in the electricity usage records shown in Fig. 4 and Fig. 5.

[0064] Also, the procedure and instructions for creating the documents may be in other formats as long as they can be created automatically. Furthermore, it is advisable to enclose the electric power company's website and its membership information, etc., in the documents sent by the operator or the responsible department via mail or fax.

[0065] In the above embodiment, the electricity usage data of the consumer measured by the smart meter is used to provide information on electricity usage such as electricity usage and electricity charges. However, in cases where gas / water systems are equipped with meters having functions similar to those of smart meters, the information provision system according to the present invention can be used to provide information on gas / water usage such as gas / water usage and charges.

[0066] Although the preferred embodiment has been described above with reference to the drawings, a person skilled in the art will easily imagine various changes and modifications within the obvious scope upon reading this specification. Therefore, such changes and modifications are interpreted as falling within the scope of the invention as defined by the claims. [Explanation of symbols]
