DETAILED DESCRIPTION OF THE INVENTION

[0013] Embodiment 1 FIG. 1 is a diagram illustrating an example of the functional configuration of a certification expiration date management device 100 according to the first embodiment. As shown in FIG. 1, the certification expiration date management device 100 is a device for managing the certification expiration date of an installed electric meter 30B, and includes a first information acquisition unit 101, a second information acquisition unit 102, and an expiration date identification unit 103. The certification expiration date management device 100 also includes a storage unit 104 in which various data is stored. As shown in FIG. 1, the certification expiration date management device 100 is connected to a network 10 so as to be able to communicate with a manufacturing management system 20 having a manufacturing database 21 and a terminal 40 operating near the installation location of the installed electric meter 30B. Here, the electric meter is a meter used for measuring electricity, such as a watt-hour meter, a current transformer, a voltage transformer, or a voltage-current transformer.

[0014] The first information acquisition unit 101 acquires manufactured meter information 50A from the manufacturing database 21. The manufactured meter information 50A is information including a serial number (corresponding to meter identification information) that identifies an individual product of the manufactured electric meter 30A, and certification expiration date information. This manufactured meter information 50A is pre-stored in the manufacturing database 21. Note that in this embodiment and each of the following embodiments, a case will be described in which the manufacturing management system 20 has the manufacturing database 21, and the certification expiration date management device 100 communicates with the manufacturing management system 20 to acquire necessary information from the manufacturing database 21, but this is not limiting. For example, the certification expiration date management device 100 may be configured to be able to directly access the manufacturing database 21.

[0015] Here, the meter identification information is information that identifies an individual electric meter product, such as a serial number that is uniquely assigned to each individual electric meter product. The certification expiration date information is information on the expiration date that is set when an electric meter passes a certification to determine whether it complies with standards. An electric meter must be renewed before the certification expiration date expires. The certification expiration date varies depending on the type and use of the electric meter.

[0016] The manufacturing database 21 stores various information related to the manufactured electric meter 30A. Specifically, it stores various information related to the electric meter obtained in the process from receiving an order, manufacturing the electric meter, to shipping the electric meter. This information includes, for example, the serial number (meter identification information) of the manufactured electric meter 30A, certification expiration date information, a product name that identifies the product type or model, a number or code (product ID) that is uniquely assigned to the product type or model, rating, size, price, order acceptance, etc.

[0017] When the first information acquisition unit 101 acquires manufactured meter information 50A including the serial number (meter identification information) and certification expiration date information of the manufactured electric meter 30A from the manufacturing database 21, the first information acquisition unit 101 may acquire information such as the product name, product ID, rating, size, price, and order acceptance / cancellation as the manufactured meter information 50A in addition to the serial number and certification expiration date information of the manufactured electric meter 30A. FIGS. 2 and 3 show examples of information stored in the manufacturing database 21. FIG. 2 shows individual product information 51A, which is information for each individual manufactured electric meter 30A. This individual product information 51A includes, for each manufactured electric meter 30A, information on the serial number, product ID, and certification expiration date. FIG. 3 shows product specification information 52A, which is specification information for each product (product type and model). This product specification information 52A includes, for each product ID, information on the product name, rating, size, price, and order acceptance / cancellation. In this embodiment, the first information acquisition unit 101 is assumed to acquire the product individual information 51A and product specification information 52A as manufactured meter information 50A. By further referring to the product specification information 52A corresponding to the product ID included in the product individual information 51A, information regarding the specifications of the manufactured electric meter 30A can be obtained.

[0018] The first information acquisition unit 101 periodically and / or non-periodically acquires the manufactured instrument information 50A. For example, the first information acquisition unit 101 may acquire the manufactured instrument information 50A by requesting the manufacturing database 21 or the manufacturing management system 20 to transmit information at any timing, or may acquire the manufactured instrument information 50A when there is a change in the manufactured instrument information 50A in the manufacturing database 21. Alternatively, the first information acquisition unit 101 may acquire the manufactured instrument information 50A periodically.

[0019] The second information acquisition unit 102 acquires installed meter information 60A from a terminal 40 operating near the installation location of the installed electric meter 30B, the installed meter information 60A including the serial number (corresponding to meter identification information) of the installed electric meter 30B obtained from the installed electric meter 30B and related party identification information that identifies related parties involved in the management of the installed electric meter 30B.

[0020] The installed electric meter 30B is provided with a serial number (corresponding to meter identification information) that can be read electrically, optically, or electromagnetically. For example, the installed electric meter 30B is provided with text information including the serial number, a QR code (registered trademark), a barcode, an IC chip, an RFID (Radio Frequency Identification) tag, or the like.

[0021] The related party refers to a person or organization directly or indirectly involved in the management of the installed electric meter 30B. Examples of related parties include the owner of the electric meter, the manager of the electric meter, and the construction company contracted to install the electric meter. Related party identification information broadly refers to information that can be used as a clue to identify the related party. The related party identification information may be unique identification information that identifies the related party, such as a number or code (manager ID) identifying the manager or a number or code (construction company ID) identifying the construction company. The related party identification information may also be the related party's email address, telephone number, company name, or name. Furthermore, if the related party managing the installed electric meter 30B in each section is known, the related party can be identified based on the location information of the installed electric meter 30B. Therefore, the location information of the installed electric meter 30B itself or the GPS (Global Positioning System) information of the terminal 40 used when reading the meter identification information from the installed electric meter 30B can also be used as the related party identification information.

[0022] The terminal 40 broadly includes terminals that operate near the installation location of the installed electric meter and can electrically, optically, or electromagnetically read the serial number from the installed electric meter 30B. The terminal 40 is a mobile terminal carried and operated by a person involved with the installed electric meter 30B or a worker of the expiration date management service provider, or an autonomous mobile robot with terminal functions. The terminal 40 has, for example, a camera function, an NFC (Near Field Communication) function, and a Bluetooth communication function, and uses these functions to read the serial number from the installed electric meter. In addition, person-identifying information is manually or automatically input into the terminal 40.

[0023] Fig. 4 shows an example of the installed meter information 60A acquired from the terminal 40. Fig. 4 shows the installed meter information 60A including the serial number (meter identification information) and the administrator ID (related party identification information) of the installed electric meter 30B. By acquiring this installed meter information 60A, when it is necessary to contact a related party regarding the installed electric meter 30B, the related party can be identified based on the related party identification information and contacted.

[0024] The second information acquisition unit 102 periodically or non-periodically performs the process of acquiring the installed meter information 60A. For example, the second information acquisition unit 102 may acquire the installed meter information 60A sent from the terminal 40 at any time, or may periodically communicate with the terminal 40 to acquire the installed meter information 60A. Alternatively, the second information acquisition unit 102 may request the terminal 40 to send information at any time and acquire the installed meter information 60A.

[0025] The expiration date specification unit 103 specifies the certification expiration date of the installed electric meter 30B based on the manufactured meter information 50A obtained by the first information obtaining unit 101 and the installed meter information 60A obtained by the second information obtaining unit 102. Specifically, the manufactured meter information 50A including meter identification information common to the installed meter information 60A is specified, and the certification expiration date of the installed electric meter 30B is specified by referring to the certification expiration date information included in the manufactured meter information 50A. When the first information acquisition unit 101 acquires the individual product information 51A and product specification information 52A shown in FIG. 2 as manufactured meter information 50A, and the second information acquisition unit 102 acquires the installed meter information 60A shown in FIG. 3, the manufactured meter information 50A "product information (meter identification information): A1, product ID: B1, certification expiration date: D1" is identified, which includes the meter identification information "A1" that is common to the installed meter information 60A, and the certification expiration date "D1" included in the manufactured meter information 50A is identified as the certification expiration date of the installed electric meter 30B.

[0026] Next, an example of processing performed by the certification expiration date management device 100 will be described with reference to the flowchart shown in Fig. 5. First, the first information acquisition unit 101 acquires manufactured meter information 50A including a serial number (meter identification information) that identifies an individual product of the manufactured electric meter 30A and certification expiration date information from the manufacturing database 21 (step S11). The first information acquisition unit 101 acquires, for example, individual product information 51A shown in Fig. 2 and product specification information 52A shown in Fig. 3 as manufactured meter information 50A.

[0027] Next, the second information acquiring unit 102 acquires the installed meter information 60A from the terminal 40 (step S12). Since electric meters shipped by the electric meter manufacturer are installed at locations designated by an administrator, the installed meter information 60A is acquired from the terminal 40 at the time of installation or at a predetermined timing after installation. For example, near the installation location of the installed electric meter 30B, a person involved with the installed electric meter 30B or another worker reads the serial number from the installed electric meter 30B using the terminal 40, such as a mobile terminal, and transmits the installed meter information 60A, which includes the read information and previously input person-specific information for the installed electric meter 30B, to the certification expiration date management device 100. The second information acquiring unit 102 of the certification expiration date management device 100 then acquires the installed meter information 60A and proceeds to the next step of processing. In addition, if the terminal 40 is an autonomous mobile robot with terminal functions, the autonomous mobile robot may be configured to sequentially execute a process of reading the serial number from the installed electric meter 30B near the installation location of the installed electric meter 30B, a process of automatically or manually obtaining related party identification information, and a process of transmitting the installed meter information 60A including this information to the certification expiration date management device 100 using a function that is pre-installed in the autonomous mobile robot.

[0028] Next, the expiration date specification unit 103 specifies the certification expiration date of the installed electric meter 30B based on the manufactured meter information 50A obtained by the first information obtaining unit 101 and the installed meter information 60A obtained by the second information obtaining unit 102 (step S13). Specifically, the manufactured meter information 50A including meter identification information common to the installed meter information 60A is specified, and the certification expiration date of the installed electric meter 30B is specified by referring to the certification expiration date information included in the manufactured meter information 50A. For example, if in step S11 the first information acquisition unit 101 acquires the individual product information 51A shown in Fig. 2 and the product specification information 52A shown in Fig. 3 as manufactured meter information 50A, and in step S12 the second information acquisition unit 102 acquires the installed meter information 60A shown in Fig. 4, in step S13 the expiration date determination unit 103 identifies the manufactured meter information 50A “product information (meter identification information): A1, product ID: B1, certification expiration date: D1” that includes the meter identification information “A1” that is common to the installed meter information 60A, and identifies the certification expiration date “D1” included in the manufactured meter information 50A as the certification expiration date of the installed electric meter 30B. Then, the process ends.

[0029] Each component of the validation expiration date management device 100 is configured by a computer having a processor 900, a memory 901, and a signal input / output unit 902, as shown in Figure 6. The functions of the first information acquisition unit 101, the second information acquisition unit 102, and the expiration date identification unit 103 are realized by this computer. That is, the memory 901 of the computer stores a program (validation expiration date management program) for realizing the functions of the first information acquisition unit 101, the second information acquisition unit 102, and the expiration date identification unit 103. In addition, various information stored in the storage unit 104 is stored in the memory 901. The processor 900 executes arithmetic processing for controlling the operation of the validation expiration date management device 100, based on the program stored in the memory 901.

[0030] As described above, the certification expiration date management device 100 of the first embodiment includes a first information acquisition unit 101 that acquires manufactured meter information 50A, including meter identification information that identifies an individual product of the manufactured electric meter 30A and certification expiration date information, from the manufacturing database 21; a second information acquisition unit 102 that acquires installed meter information 60A, including the meter identification information of the installed electric meter 30B obtained from the installed electric meter 30B and related party identification information of the installed electric meter, from a terminal 40 that operates near the installation location of the installed electric meter 30B; and an expiration date determination unit 103 that determines the certification expiration date of the installed electric meter 30B based on the manufactured meter information 50A and the installed meter information 60A, including the common meter identification information. This makes it possible to easily obtain and manage information about the certification expiration date of the installed electric meter 30B, even if the certification expiration date of the installed electric meter 30B is not known in advance.

[0031] In the above embodiment, the case where the first information acquisition unit 101 acquires the individual product information 51A and the product specification information 52A as the manufactured meter information 50A has been described. However, the manufactured meter information 50A acquired by the first information acquisition unit 101 only needs to include at least the meter identification information and the certification expiration date information of the manufactured electric meter, and acquisition of other information may be omitted.

[0032] Embodiment 2 Fig. 7 is a diagram showing an example of the functional configuration of a certification expiration date management device 200 according to embodiment 2. As shown in Fig. 7, embodiment 2 differs from the first embodiment in that a first information acquisition unit 201 acquires manufactured meter information 50A from a manufacturing database 21, the manufactured meter information 50A including meter identification information that is common to installed meter information 60A acquired by a second information acquisition unit 102. The following explanation will focus on this difference, and components similar to those in the first embodiment will be assigned the same reference numerals and will not be described in detail.

[0033] When the second information acquisition unit 102 acquires the installed meter information 60A from the terminal 40, the first information acquisition unit 201 obtains the meter identification information of the installed electric meter included in the installed meter information 60A, and requests the manufacturing management system 20 to transmit manufactured meter information 50A having meter identification information that matches the installed meter identification information, thereby acquiring the manufactured meter information 50A from the manufacturing database 21. Note that the first information acquisition unit 201 may directly access the manufacturing database 21 to acquire the manufactured meter information 50A that includes meter identification information that is common to the installed meter information 60A.

[0034] Next, an example of processing performed by the verification expiration date management device 200 will be described with reference to the flowchart shown in Fig. 8. First, the second information acquisition unit 102 acquires installed meter information 60A from the terminal 40 (step S21). Next, the first information acquisition unit 201 acquires manufactured meter information 50A including meter identification information that is common to the installed meter information 60A acquired in step S21 from the manufacturing database 21 (step S22). Specifically, the first information acquisition unit 201 obtains the meter identification information of the installed electric meter included in the installed meter information 60A acquired in step S21, requests the manufacturing management system 20 to transmit manufactured meter information 50A having meter identification information that matches the meter identification information, and acquires the manufactured meter information 50A from the manufacturing database 21. Next, the expiration date specifying unit 103 specifies the certification expiration date of the installed electric meter 30B based on the installed meter information 60A obtained in step S21 and the manufactured meter information 50A obtained in step S22 (step S23). Then, the process ends.

[0035] As described above, the certification expiration date management device 200 of embodiment 2 includes a second information acquisition unit 102 that acquires installed meter information 60A, which includes the meter identification information of the installed electric meter 30B obtained from the installed electric meter 30B and the relevant person identification information of the installed electric meter 30B, from the terminal 40 operating near the installation location of the installed electric meter 30B; a first information acquisition unit 201 that acquires manufactured meter information 50A, which includes the meter identification information and certification expiration date information of the manufactured electric meter 30A, from the manufacturing database 21 in which the manufactured meter information 50A is pre-stored, the manufactured meter information 50A including meter identification information common to the installed meter information 60A; and an expiration date identification unit 103 that identifies the certification expiration date of the installed electric meter 30B based on the manufactured meter information 50A including the common meter identification information and the installed meter information 60A. This makes it possible to easily obtain and manage information about the certification expiration date of the installed electric meter 30B even if the certification expiration date is not known in advance. Furthermore, since the first information obtaining unit 201 does not need to obtain manufactured meter information about electric meters that are not subject to management, the amount of information to be obtained can be reduced.

[0036] Embodiment 3 Fig. 9 is a diagram illustrating an example of the functional configuration of a verification expiration date management device 300 according to embodiment 3. As illustrated in Fig. 9, embodiment 3 differs from the first embodiment in that the manufactured electric meter 31A and the installed electric meter 31B include multiple types of electric meters, such as a watt-hour meter with a transformer, and in that the first information acquisition unit 301 acquires manufactured meter information 50B related to each of the multiple types of electric meters included in the manufactured electric meter 31A from the manufacturing database 21. The certification expiration date management device 300 also differs from the first embodiment in that the second information acquisition unit 302 acquires, from the terminal 40, installed meter information 60B including meter identification information obtained from at least one of the electric meters included in the installed electric meter 31B and related party identification information that identifies a related party of the installed electric meter 31B, and in that the expiration date identification unit 303 identifies the certification expiration date for each of the multiple types of electric meters included in the installed electric meter 31B based on the manufactured meter information 50B acquired by the first information acquisition unit 301 and the installed meter information 60B acquired by the second information acquisition unit 102. The following explanation will focus on these differences, and the same components as those in the first or second embodiment will be denoted by the same reference numerals and will not be described in detail.

[0037] The first information acquisition unit 301 acquires manufactured meter information 50B related to a manufactured electric meter 31A by making a request to the manufacturing database 21 or the manufacturing management system 20. In this embodiment, the manufactured electric meter 31A refers to a watt-hour meter and, if the watt-hour meter is equipped with a transformer, a voltage transformer and a current transformer used in combination with the watt-hour meter. FIGS. 10, 11, 12, and 13 show examples of information stored in the manufacturing database 21. FIG. 10 shows product individual information 51B, which includes, for each watt-hour meter's serial number (meter identification information), the product ID of the watt-hour meter, the watt-hour meter's certification expiration date, the transformer's product ID, the transformer's certification expiration date, the current transformer's product ID, and the current transformer's certification expiration date. FIG. 11 shows first product specification information 52B, which includes, for each watt-hour meter's product ID, the product name, rating, size, price, and order acceptance / non-acceptance information. 12 shows second product specification information 53B, which includes information on the product name, rating, price, and order acceptance status for each transformer product ID. FIG. 13 shows third product specification information 54B, which includes information on the product name, rating, price, and order acceptance status for each current transformer product ID. In this embodiment, the first information acquisition unit 301 acquires product individual information 51B, first product specification information 52B, second product specification information 53B, and third product specification information 54B as manufactured meter information 50B. By further referencing the first product specification information 52B, second product specification information 53B, or third product specification information 54B corresponding to each product ID included in the product individual information 51A, information on the specifications of the manufactured electric meter 31A can be obtained.

[0038] The second information acquisition unit 302 acquires installed meter information 60B, which includes meter identification information obtained from at least one of the electric meters included in the installed electric meter 31B and related person identification information related to the installed electric meter 31B, from a terminal 40 operating near the installation location of the installed electric meter 31B. Fig. 14 shows an example of the installed meter information 60B acquired from the terminal 40. The installed meter information 60B shown in Fig. 14 includes the serial number (equivalent to meter identification information) of an installed electric meter that is one of the installed electric meters 31B, and the administrator ID (related person identification information) of the installed electric meter 31B.

[0039] The expiration date determination unit 303 determines the certification expiration date of the installed electric meter 31B based on the manufactured meter information 50B obtained by the first information acquisition unit 301 and the installed meter information 60B obtained by the second information acquisition unit 302. Specifically, the manufactured meter information 50B including the meter identification information of a watthour meter that is common to the installed meter information 60B is identified, and the certification expiration date of each electric meter included in the installed electric meter 31B is determined based on the certification expiration date information of each electric meter included in the manufactured meter information 50B. For example, consider a case where the first information acquisition unit 301 acquires, as the manufactured meter information 50B, product individual information 51B shown in FIG. 10, first product specification information 52B shown in FIG. 11, second product specification information 53B shown in FIG. 12, and third product specification information 54B shown in FIG. 13, and the second information acquisition unit 302 acquires the installed meter information 60B shown in FIG. 14. First, manufactured meter information 50B is identified, which includes the meter identification information "A1" of the watthour meter that is common to installed meter information 60B: "Watthour meter serial number (meter identification information): A1, watthour meter product ID: B1, watthour meter certification expiration date: D1, transformer product ID: E1, transformer certification expiration date: F1, current transformer product ID: G1, current transformer certification expiration date: H1." Then, based on the "watthour meter certification expiration date: D1, transformer certification expiration date: F1, current transformer certification expiration date: H1" included in manufactured meter information 50B, it is identified that the certification expiration date of the watthour meter, the certification expiration date of the transformer, and the certification expiration date of the current transformer are "D1," "F1," and "H1," respectively, included in installed electric meter 31B.

[0040] As described above, the certification expiration date management device 300 of the third embodiment includes a first information acquisition unit 301 that acquires manufactured meter information 50B for each of the multiple types of electric meters included in the manufactured electric meter 31A from the manufacturing database 21, a second information acquisition unit 102 that acquires installed meter information 60B from a terminal 40 that operates near the installation location of the installed electric meter 31B, the installed meter information 60B including meter identification information obtained from at least one of the electric meters included in the installed electric meter 31B and related party identification information that identifies a related party of the installed electric meter 31B, and an expiration date identification unit 303 that identifies the certification expiration date information of the installed electric meter 31B based on the manufactured meter information 50B and the installed meter information 60B, both of which include common meter identification information. This makes it possible to easily obtain and manage the certification expiration date information of the installed electric meter 31B, even if the certification expiration date of the installed electric meter 31B is not known in advance. Furthermore, the manufactured electric meter 31A and the installed electric meter 31B can manage the certification expiration dates of a plurality of types of electric meters by linking them to meter identification information relating to at least one common electric meter.

[0041] Embodiment 4 FIG. 15 is a diagram illustrating an example of the functional configuration of a certification expiration date management device 400 according to the fourth embodiment. As illustrated in FIG. 15, the fourth embodiment differs from the first embodiment in that the expiration date determination unit 403 creates managed meter information 70 that links together meter identification information common to the manufactured meter information 50A and the installed meter information 60A, the certification expiration date information of the manufactured meter information 50A that includes the common meter identification information, and the related party identification information of the installed meter information 60A that includes the common meter identification information, and determines the certification expiration date of the installed electric meter 30B based on the managed meter information 70. Furthermore, this embodiment describes a case in which a management database 405 is created in a storage unit 404, and the managed meter information 70 is registered in the management database 405 and used to determine the certification expiration date. Note that components similar to those in the first to third embodiments are designated by the same reference numerals, and detailed description thereof will be omitted.

[0042] The first information acquisition unit 101 acquires manufactured meter information 50A from the manufacturing database 21. The acquired manufactured meter information 50A is stored in the storage unit 404. The second information acquisition unit 102 acquires installed meter information 60A from a terminal 40 operating near the installation location of the installed electric meter 30B. The acquired installed meter information 60A is stored in the storage unit 404.

[0043] The expiration date specification unit 403 references the manufactured meter information 50A and the installed meter information 60A stored in the storage unit 404 to specify the manufactured meter information 50A and the installed meter information 60A that contain common meter identification information, creates managed meter information 70 by linking the relevant party identification information contained in the specified installed meter information 60A with the meter identification information and certification expiration date information contained in the specified manufactured meter information 50A, and registers the managed meter information 70 in the management database 405. In this case, the managed meter information 70 may include information such as the product name, product ID, rating, size, price, and order acceptance / non-acceptance in addition to the meter identification information, relevant party identification information, and certification expiration date information. FIG. 16 shows an example of the managed meter information 70. FIG. 16 shows the managed meter information 70, which includes the product ID, administrator ID (relevant party identification information), and certification expiration date information for each serial number (meter identification number) of each electric meter. Then, the expiration date specification unit 403 specifies the certification expiration date of the installed electric meter 30B using the managed meter information 70 registered in the management database 405.

[0044] Here, the management database 405 is a database used to manage the management instrument information 70, and is provided with a table made up of fields for storing information on the management instrument information 70. Note that, in this embodiment, a case will be described in which the management database 405 is constructed in the storage unit 404 of the certification expiration date management device 400, but this is not limiting. The management database 405 may also be constructed in the storage unit of a device other than the certification expiration date management device 400, or on the cloud.

[0045] A specific example of processing performed by the expiration date identifying unit 403 will be described below with reference to the drawings. Here, a case will be described in which the first information acquiring unit 101 acquires the product individual information 51A and product specification information 52A shown in Fig. 2 as manufactured instrument information 50A, the second information acquiring unit 102 acquires the installed instrument information 60A shown in Fig. 3, and the expiration date identifying unit 403 creates the managed instrument information 70 shown in Fig. 16. From the acquired manufactured instrument information 50A, the expiration date identifying unit 403 stores information that matches the fields of the table of managed instrument information 70 provided in the management database 405 as the managed instrument information 70. The table of managed instrument information 70 shown in Fig. 16 provided in the management database 405 is composed of fields consisting of the serial number (instrument identification number), product ID, administrator ID (related person identification information), and certification expiration date information. 2 contains information other than the administrator ID field of the managed meter information 70, the expiration date determination unit 403 registers the serial number (instrument identification number), product ID, and certification expiration date information in the management database 405 as information from the manufactured meter information 50A. Next, the expiration date determination unit 403 registers the relevant party identification information from the acquired installed meter information 60A in the management database 405. Specifically, the expiration date determination unit 403 searches the meter identification information field of the managed meter information 70 in the management database 405 to find meter identification information that matches the meter identification information in the installed meter information 60A. The relevant party identification information contained in the installed meter information 60A is registered in the managed party identification information field corresponding to the relevant meter identification information, and the managed meter information 70 shown in FIG. 16 is completed. The expiration date determination unit 403 then determines "Serial number (meter identification information): A1, Product ID: B1, Certification expiration date: D1" from the management meter information 70 registered in the management database 405, and determines the certification expiration date "D1" as the certification expiration date of the installed electric meter 30B.

[0046] As described above, the certification expiration date management device 400 of the fourth embodiment includes a first information acquisition unit 101 that acquires manufactured meter information 50A, including meter identification information for identifying an individual product of the manufactured electric meter 30A and certification expiration date information, from the manufacturing database 21, and a second information acquisition unit 102 that acquires installed meter information 60A, including the meter identification information of the installed electric meter obtained from the installed electric meter 30B and related person identification information of the installed electric meter, from an operating device near the installation location of the installed electric meter 30B. and an expiration date specification unit 403 that creates managed meter information 70 that links together meter identification information common to the manufactured meter information 50A and the installed meter information 60A, the certification expiration date information of the manufactured meter information 50A that includes the common meter identification information, and the related party specification information of the installed meter information 60A that includes the common meter identification information, and specifies the certification expiration date of the installed electric meter 30B based on the managed meter information 70. This makes it possible to easily obtain and manage information about the certification expiration date of the installed electric meter 30B even if the certification expiration date of the installed electric meter 30B is not known in advance.

[0047] In the above fourth embodiment, the case has been described in which the expiration date determining unit 403 creates the managed meter information 70 by linking the meter identification information and certification expiration date information included in the manufactured meter information 50A with the related party identifying information of the installed meter information 60A that includes common meter identification information, but the present invention is not limited to this. For example, the expiration date determining unit 403 may create the managed meter information 70 by linking the certification expiration date information of the manufactured meter information 50A that includes common meter identification information with the meter identification information and related party identifying information included in the installed meter information 60A.

[0048] In addition, in the above-described fourth embodiment, the manufactured meter information 50A and the installed meter information 60A are stored in the storage unit 404, but this storage process may be omitted. The expiration date identification unit 403 may create and register managed meter information 70 in the management database 405 using the manufactured meter information 50A acquired by the first information acquisition unit and the installed meter information 60A acquired by the second information acquisition unit.

[0049] Embodiment 5 FIG. 17 is a diagram illustrating an example of the functional configuration of a certification expiration date management device 500 according to the fifth embodiment. As illustrated in FIG. 17, the fifth embodiment differs from the first embodiment in that it further includes an update target extraction unit 505 that extracts, as an update target meter 30C, an installed electric meter whose remaining time until the certification expiration date falls below a predetermined value, based on the certification expiration date information identified by the expiration date identification unit 403, and a notification unit 506 that notifies a related party identified by the related party identification information of information related to the update of the update target meter 30C. In this embodiment, a case will be described in which related party information 80, which is referenced together with the related party identification information, is previously stored in the storage unit 504. The following description will focus on this difference, and the same components as those in the first to fourth embodiments will be denoted by the same reference numerals and will not be described in detail.

[0050] The storage unit 504 stores manufactured meter information 50A acquired by the first information acquisition unit 101 and installed meter information 60A acquired by the second information acquisition unit 102. The storage unit 504 also stores in advance related party information 80, which is related information such as contact information for each related party. The related party information 80 is referenced together with related party identification information when the notification unit 506 performs notification processing to the related party. The related party information 80 can be acquired when a contract is concluded between the expiration date management service provider and the related party. FIGS. 18 and 19 show examples of related party information 80. FIG. 18 shows administrator information 81, which includes information on the name, contact information, and construction company ID for each administrator ID. FIG. 19 shows construction company information 82, which includes information on the company name and contact information for each construction company ID.

[0051] Based on the certification expiration date information identified by the expiration date identification unit 403, the update target extraction unit 505 extracts, as the update target meter 30C, an installed electric meter whose remaining time until the certification expiration date is less than a predetermined value. Specifically, consider a case where the expiration date identification unit 403 identifies that the certification expiration date of the installed electric meter 30B (hereinafter, the installed electric meter 30B "A1") having meter identification information "A1" is "D1" based on the manufactured meter information 50A including the product individual information 51A shown in FIG. 2 and the product specification information 52A shown in FIG. 3, and the installed meter information 60A shown in FIG. 4. First, the update target extraction unit 505 determines whether the remaining time until the certification expiration date "D1" of the installed electric meter 30B "A1" is less than a predetermined value. If the remaining time is less than the predetermined value, the update target extraction unit 505 extracts the installed electric meter 30B "A1" as the update target meter 30C. There is no particular restriction on the method for determining whether the remaining time until the certification expiration date is less than a predetermined value, but for example, it can be determined by whether the difference between the certification expiration date and the current date is less than a predetermined value. The current date can be obtained by the certification expiration date management device 500 from an external time server via a network. The predetermined value can be set arbitrarily, taking into account the number of days required for the electric meter update process.

[0052] The notification unit 506 notifies related parties who are directly or indirectly involved in the management of the installed electric meter 30B of information related to the update of the update target meter 30C. Specifically, consider a case where the update target extraction unit 505 determines that the installed electric meter 30B "A1" is the update target meter 30C. First, the notification unit 506 identifies related parties involved in the management of the installed electric meter 30B based on related party identification information included in the installed meter information 60A shown in FIG. 4. Furthermore, the notification unit 506 obtains related information such as the related party's contact information by referring to the related party information 80 stored in the storage unit 504, as shown in FIGS. 18 and 19. From the installed meter information 60A shown in FIG. 4, related party identification information (administrator ID) "C1" linked to the meter identification information "A1" of the update target meter 30C can be identified. Furthermore, by further referring to the administrator information 81 corresponding to the administrator ID "C1" common to the installed meter information 60A in the administrator information 81 shown in FIG. 18, related information such as the administrator's contact information can be obtained. Furthermore, the construction company ID "K1" linked to the administrator ID "C1" in the administrator information 81 can be used to further reference the construction company information 82 corresponding to the construction company ID "K1" in the construction company information 82 shown in FIG. 19 to obtain related information such as the construction company's contact information. The obtained information can then be used to notify the administrator or construction company of information related to the update of the meter 30C to be updated. The information related to the update of the meter 30C to be updated may be any information that triggers the relevant parties to consider updating the installed electric meter 30B upon receiving the notification. For example, the information may be information about the expiration date of the certification or information that the expiration date of the certification is approaching. It may also be information indicating the need for updating, or information that is useful when considering updating. Information useful when considering updating may be, for example, information about the replacement meter 30D, information about a proposal for installation of the replacement meter 30D, etc.

[0053] Next, an example of processing performed by the certification expiration date management device 500 will be described with reference to the flowchart shown in FIG. 20. The processing content shown in FIG. 20 is assumed to be performed after the processing by the first information acquisition unit 101, the second information acquisition unit 102, and the expiration date identification unit 403. First, the update target extraction unit 505 acquires certification expiration date information for the installed electric meter 30B identified by the expiration date identification unit 403 (step S31). Next, the update target extraction unit 505 determines whether the remaining period until the certification expiration date of the installed electric meter 30B acquired in step S31 is less than a predetermined value (step S32). The installed electric meter 30B whose remaining period until the certification expiration date is less than the predetermined value is extracted as an update target meter 30C. If an update target meter 30C is found, the process proceeds to step S33; if not, the process ends. The notification unit 506 identifies a related person of the installed electric meter 30B using the related person identification information. At this time, the related person information 80 is further referenced to obtain related information such as contact information (step S33). Then, the notification unit 506 notifies the relevant parties identified in step S33 of information relating to the update of the update target instrument 30C (step S34), after which the process ends.

[0054] As described above, the certification expiration date management device 500 of the fifth embodiment includes a first information acquisition unit 101 that acquires manufactured meter information 50A, including meter identification information for identifying an individual product of the manufactured electric meter 30A and certification expiration date information, from the manufacturing database 21, and a second information acquisition unit that acquires installed meter information 60A, including meter identification information of the installed electric meter obtained from the installed electric meter 30B and related person identification information of the installed electric meter, from a terminal 40 that operates near the installation location of the installed electric meter 30B. The system includes a verification unit 102, an expiration date specification unit 403 that specifies the certification expiration date information of the installed electric meter 30B based on the manufactured meter information 50A and the installed meter information 60A, which include common meter identification information, an update target extraction unit 505 that extracts, as an update target meter 30C, an installed electric meter 30B whose remaining time until the certification expiration date is less than a predetermined value based on the specified certification expiration date information, and a notification unit 506 that notifies relevant parties of the installed electric meter 30B about information related to the update of the update target meter 30C. This makes it possible to easily obtain and manage information about the certification expiration date of the installed electric meter 30B even if the certification expiration date of the installed electric meter 30B is not known in advance. Furthermore, by including the update target extraction unit 505 and the notification unit 506, relevant parties can be notified about information related to the update of the update target meter 30C whose certification expiration date is approaching, and the relevant parties can receive the notification and take the necessary measures to update the electric meter before the certification expiration date expires.

[0055] In the fifth embodiment, the manufactured instrument information 50A, the installed instrument information 60A, and the related party information 80 are stored in the storage unit 504, but this is not limiting. For example, instead of the manufactured instrument information 50A and the installed instrument information 60A, the storage unit 504 may store the managed instrument information 70 created by the expiration date identification unit 403, and the update target extraction unit 505 and the notification unit 506 may use the managed instrument information 70.

[0056] Embodiment 6 FIG. 21 is a diagram illustrating an example of the functional configuration of a certification expiration date management device 600 according to the sixth embodiment. As illustrated in FIG. 21, the sixth embodiment differs from the fifth embodiment in that it further includes a selection unit 607 that selects a replacement meter 30D to be used to update the target meter 30C, and an order management unit 608 that has the functions of outputting order information for ordering the replacement meter 30D and outputting installation request information for requesting a contractor to install the replacement meter 30D. This embodiment also assumes that the certification expiration date management device 600 is connected to a network 10 so as to be able to communicate with an installation order receiving system 90. The following description will focus on this difference, and the same components as those in the first to fifth embodiments will be designated by the same reference numerals and will not be described in detail.

[0057] The selection unit 607 selects a replacement meter 30D to be used to update the update target meter 30C extracted by the update target extraction unit 505. The selection unit 607 selects the replacement meter 30D by referencing the manufactured meter information 50A linked to the meter identification information of the update target meter 30C. Specifically, a case will be described in which the update target extraction unit 505 extracts an installed electric meter 30B with meter identification information "A1" as the update target meter 30C from the manufactured meter information 50A made up of the product individual information 51A shown in FIG. 2 and the product specification information 52A shown in FIG. 3, and the installed meter information 60A shown in FIG. 4. The selection unit 607 identifies the product ID "B1" linked to the manufacturing number (meter identification information) "A1" in the product individual information 51A shown in FIG. 2. In the product specification information 52A shown in FIG. 3, the order availability is identified as "available" or "unavailable" based on the "Product Name: N1, Rating: O1, Size: X1, Y1, Z1 (height, width, depth), Price: P1, Order Availability: Unavailable" associated with the product ID "B1." If the order availability is "available," an electric meter with the same product ID is selected. If the order availability is "unavailable," because the same model has been discontinued, a replacement model is selected based on the rating "O1," size "X1, Y1, Z1 (height, width, depth)," and price "P1." For example, items with the same rating as the replacement target meter 30C are extracted, and from those, items with the same or smaller size as the replacement target meter 30C are extracted. If there are multiple electric meters with the same conditions, price may be used as a reference for selection. Note that size and price may simply be presented as information on the replacement product.

[0058] The order management unit 608 outputs order information for ordering the replacement meter 30D to the manufacturing management system 20 based on the intentions of the relevant parties regarding the ordering of the replacement meter 30D. Specifically, the order management unit 608 proposes ordering the replacement meter 30D to the relevant parties and inquires whether or not to place the order. Upon receiving a notification from the relevant parties agreeing to the order, the order management unit 608 outputs the order information to the manufacturing management system 20. The order information is information necessary for ordering the replacement meter 30D, such as information such as a product ID that identifies the model and product type of the replacement meter 30D, and information about the relevant parties who are the delivery destinations. In addition, the order information may include information about the meter 30C to be updated. This order information is extracted from the relevant party information 80, manufactured meter information 50A, installed meter information 60A, etc.

[0059] Furthermore, based on the intentions of the parties concerned regarding the installation of the replacement meter 30D, the order management unit 608 outputs installation work request information to the installation order receiving system 90 owned by the construction company to request an installation contractor to install the replacement meter 30D. Specifically, the order management unit 608 proposes the installation of the replacement meter 30D to the parties concerned and inquires whether or not to request the installation work. Upon receiving a message from the parties concerned agreeing to the installation work request, the order management unit 608 outputs the installation work request information to the installation order receiving system 90. The installation work request information is information required for the installation of the replacement meter 30D, such as information about the replacement meter 30D, information about the meter to be updated 30C, and information about the parties concerned at the installation site. This installation work request information is extracted from the parties concerned information 80, the manufactured meter information 50A, the installed meter information 60A, etc.

[0060] Next, an example of processing performed by the certification expiration date management device 600 will be described with reference to the flowchart shown in FIG. 22. The processing content shown in FIG. 22 is assumed to be performed after processing by the first information acquisition unit 101, the second information acquisition unit 102, the expiration date identification unit 403, and the update target extraction unit 505. First, the selection unit 607 selects a replacement meter 30D to be used to update the update target meter 30C extracted by the update target extraction unit 505 (step S41). Next, the order management unit 608 performs ordering processing for the replacement meter 30D (step S42). Specifically, the order management unit 608 proposes ordering the replacement meter 30D to the relevant parties, receives a message from the relevant parties agreeing to the order, and outputs order information to the manufacturing management system 20. Next, the order management unit 608 requests installation of the replacement meter 30D (step S43). Specifically, the order management unit 608 proposes the installation of the replacement meter 30D to the relevant parties, receives a message from the relevant parties agreeing to the installation, and outputs installation request information to the installation order receiving system 90. Then, the process ends.

[0061] As described above, the certification expiration date management device 600 of the sixth embodiment includes a first information acquisition unit 101 that acquires manufactured meter information 50A including meter identification information for identifying an individual product of the manufactured electric meter 30A and certification expiration date information from the manufacturing database 21, a second information acquisition unit 102 that acquires installed meter information 60A including meter identification information of the installed electric meter obtained from the installed electric meter 30B and related person identification information of the installed electric meter from the terminal 40 that operates near the installation location of the installed electric meter 30B, and a second information acquisition unit 103 that acquires the manufactured meter information 50A including common meter identification information and the installed meter information 60A from the terminal 40 that operates near the installation location of the installed electric meter 30B. The system includes an expiration date specification unit 403 that specifies the certification expiration date information of the installed electric meter 30B, an update target extraction unit 505 that extracts, as an update target meter 30C, an installed electric meter 30B whose remaining time until the certification expiration date is less than a predetermined value based on the specified certification expiration date information, a notification unit 506 that notifies the parties involved in the update target meter 30C about information related to the update of the update target meter 30C, a selection unit 607 that selects a replacement meter 30D to be used to update the update target meter 30C, and an order management unit 608 that outputs ordering information for ordering the replacement meter 30D and installation request information for requesting a contractor to install the replacement meter 30D. This makes it possible to easily obtain and manage information about the certification expiration date of an installed electric meter 30B even if the certification expiration date is not known in advance. Furthermore, by providing a selection unit 607 and an order management unit 608, it is possible to smoothly update electric meters whose certification expiration date is approaching by selecting a replacement meter 30D to be used to update the meter 30C to be updated whose certification expiration date is approaching, and ordering the replacement meter 30D and the installation work.

[0062] In the above embodiment, the order management unit 608 has been described as having two functions: a function to output order information for ordering a replacement meter 30D, and a function to output installation work request information for requesting a contractor to install the replacement meter 30D. However, the unit may be configured to have only one of these functions as needed.

[0063] In the above embodiment, a step of confirming the intentions of the parties involved before outputting the order information for the selected replacement meter 30D is described, but if there is a prior agreement between the parties involved, the step of confirming the intentions of the parties involved may be omitted. Similarly, when ordering installation work, if there is a prior agreement between the parties involved, the step of confirming the intentions of the parties involved before outputting the installation work request information may be omitted.

[0064] Furthermore, after the replacement meter 30D is installed, the first information acquisition unit 101 acquires manufactured meter information 50A about the replacement meter 30D, the second information acquisition unit 102 acquires installed meter information 60A including meter identification information about the replacement meter 30D, and the expiration date determination unit 403 determines the certification expiration date of the replacement meter 30D based on the manufactured meter information 50A and the installed meter information 60A. This allows certification expiration date management to be performed for the updated electric meter as well. The first information acquisition unit 101 may acquire the manufactured meter information 50A about the replacement meter 30D before the installation. For example, the manufacturing management system 20 may ship the replacement meter 30D based on order information from the order management unit 608 of the certification expiration date management device 600, and then transmit the manufactured meter information 50A about the shipped replacement meter 30D to the first information acquisition unit 101 of the certification expiration date management device 600.

[0065] Furthermore, if the product IDs of the update target meter 30C and the replacement meter 30D are the same and the storage unit 504 or the like holds the controlled meter information 70 related to the update target meter 30C, the process of identifying the certification expiration date of the replacement meter 30D by the expiration date identification unit 403 can be simplified. For example, the information in the controlled meter information 70, such as the meter identification information and certification expiration date information of the update target meter 30C, may be overwritten and updated with the information of the replacement meter 30D.

[0066] If the electric meters to be managed are watthour meters with transformers including a watthour meter, a transformer, and a current transformer, and only the watthour meter is to be updated due to differences in the certification expiration dates, manufactured meter information 50B and installed meter information 60B of the replacement watthour meter may be linked to information such as the product IDs and certification expiration dates of the transformers and current transformers combined with the watthour meter to be updated, and used to manage the expiration dates.
