Description

[Technical field]

[0001] The present invention relates to a recycling support system and a recycling support method. [Background technology]

[0002] Conventionally, in recycling, a method is known in which an identification code or the like is assigned to a product to facilitate access to a database (DB) and the database is shared with a third party (for example, Patent Document 1). Patent Document 1 describes a recycling device that "has an input means for reading first product information attached to the equipment, a storage means for storing an equipment recovery and dismantling information database of information for matching, dismantling, and sorting the equipment corresponding to the first product information attached to the equipment, and a matching means for matching the first product information of the equipment obtained by the input means with the equipment corresponding to the equipment recovery and dismantling information database."

[0003] [Patent Document 1] JP 2002-197147 A Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional methods such as that described in Patent Document 1, changing the scope of information to be disclosed about various recyclable items, including products and parts, according to the access authority of the person accessing the item is not taken into consideration. Information about recyclable items, such as the composition of products and parts, as well as the efficient order of disassembly or the method of sorting, can be said to be information that has added value in itself. In conventional methods, such added-value information is disclosed without limit, for example, to third-party dismantler companies that do not do business with the company. As a result, it was not possible to meet the needs of dividing the levels of information to be disclosed about recyclable items and changing the scope of disclosure of the information, such as providing information preferentially to dismantler companies that do business with the company.

[0005] An object of the present invention is to provide a technique that makes it possible to change the scope of disclosure of information about a recyclable object depending on the authority of a person accessing the recyclable object. [Means for solving the problem]

[0006] The recycling support system of the present invention is a recycling support system that supports the recycling of recycling items by disclosing information about the recycling items using a computer having a processor and memory, wherein the processor authenticates the user based on the user's authentication information and the user's registered authentication information inputted to the computer, and changes the range of information about the recycling items to be disclosed in accordance with the access level of the authenticated user using identification information attached to the recycling items and access authority information that defines the access level to information about the recycling items for each user. Effect of the Invention

[0007] According to the present invention, the scope of information regarding a recyclable object to be made public can be changed depending on the authority of the person accessing the recyclable object. [Brief description of the drawings]

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The examples are illustrative for explaining the present invention, and are omitted and simplified as appropriate for clarity of explanation. The present invention can be implemented in various other forms. Unless otherwise limited, each component may be singular or plural. The position, size, shape, range, etc. of each component shown in the drawings may not represent the actual position, size, shape, range, etc., in order to facilitate understanding of the invention. Therefore, the present invention is not necessarily limited to the position, size, shape, range, etc. disclosed in the drawings.

[0010] As examples of various information, the various information may be described using expressions such as "table," "list," and "queue," but the various information may be expressed using data structures other than these. For example, various information such as "XX table," "XX list," and "XX queue" may be expressed as "XX information." When describing identification information, expressions such as "identification information," "identifier," "name," "ID," and "number" are used, but these are mutually interchangeable.

[0011] When there are multiple components having the same or similar functions, they may be described by using the same reference numerals with different subscripts, or when there is no need to distinguish between these multiple components, the subscripts may be omitted.

[0012] In the embodiments, a process performed by executing a program may be described. Here, a computer executes the program using a processor (e.g., CPU, GPU), and performs the process defined by the program while using a storage resource (e.g., memory) and an interface device (e.g., communication port), etc. Therefore, the subject of the process performed by executing the program may be the processor. Similarly, the subject of the process performed by executing the program may be a controller, device, system, computer, or node having a processor. The subject of the process performed by executing the program may be a calculation unit, and may include a dedicated circuit that performs specific processing. Here, the dedicated circuit is, for example, an FPGA (Field Programmable Gate Array), an ASIC (Application Specific Integrated Circuit), or a CPLD (Complex Programmable Logic Device), etc.

[0013] The program may be installed in the computer from a program source. The program source may be, for example, a program distribution server or a computer-readable storage medium. When the program source is a program distribution server, the program distribution server may include a processor and a storage resource that stores the program to be distributed, and the processor of the program distribution server may distribute the program to be distributed to other computers. In addition, in the embodiment, two or more programs may be realized as one program, and one program may be realized as two or more programs.

[0014] 1 is a diagram showing the functional configuration of a recycling support system according to an embodiment of the present invention. The recycling support system 1000 according to this embodiment includes a terminal 100 for acquiring identification information C attached to various products and parts T (hereinafter simply referred to as recycling objects) to be recycled, an authentication server 200 for providing information about the recycling object T based on authentication of the terminal 100 and a determination of the access level to information about the recycling object T, and an information server 300 for storing information about the recycling object T. In the following, the recycling object T is described on the assumption that it is a product or part, but this system is not limited to these, and can be applied to various items determined as recycling target items such as switchboards, electrical equipment, and cars.

[0015] The terminal 100, the authentication server 200, and the information server 300 shown in Fig. 1 can be realized by a general computer 1600 including a CPU 1601, a memory 1602, an external storage device 1603 such as a hard disk drive (HDD), a reading / writing device 1607 for reading and writing information from a portable storage medium 1608 such as a compact disk (CD) or a USB memory, an input device 1606 for receiving input of various information such as a keyboard, a mouse, a reader, and a scanner, an output device 1605 such as a display for outputting various information inputted and used for processing, a communication device 1604 such as a network interface card (NIC) for connecting to a communication network, and an internal communication line (called a system bus) 1609 such as a system bus connecting them, as shown in Fig. 2 (schematic diagram of a computer). If the computer 1600 is a mobile terminal such as a smartphone, it does not necessarily have to include the reading / writing device 1607.

[0016] Moreover, various data stored in these terminals and servers or used for processing can be realized by the CPU 1601 reading and using it from the memory 1602 or the external storage device 1603. Moreover, each unit of these terminals and servers (for example, the access range determination unit 202 of the authentication server 200) can be realized by the CPU 1601 loading a predetermined program stored in the external storage device 1603 into the memory 1602 and executing it.

[0017] The above-mentioned predetermined programs and data may be stored (downloaded) in the external storage device 1603 from the storage medium 1608 via the reading / writing device 1607 or from the network via the communication device 1604, and then loaded onto the memory 1602 and executed by the CPU 1601. Alternatively, the programs and data may be directly loaded onto the memory 1602 from the storage medium 1608 via the reading / writing device 1607 or from the network via the communication device 1604, and executed by the CPU 1601.

[0018] In the following, an example is given in which these terminals and servers are configured by one computer, but all or part of these functions may be distributed among one or more computers, such as a cloud, and similar functions may be realized by communicating with each other via a network. Also, the information server 300 may be a single physical server that also serves as the authentication server 200. First, the terminal 100 will be described.

[0019] The terminal 100 is a terminal for requesting information about a recycling object T identified by identification information C attached to the recycling object T, and displaying the information obtained by the request. For example, a smartphone may be used as the terminal 100.

[0020] As shown in FIG. 1, the terminal 100 includes a screen display unit 101, a reading unit 120, and a control unit 103.

[0021] The screen display unit 101 displays, on a screen of the output device 1605 or the like, various types of information used in the present system, such as an authentication screen for a user to perform authentication for the present system, and information received from the authentication server 200.

[0022] Fig. 3 is a diagram showing an example of an authentication screen displayed by screen display unit 101. As shown in Fig. 3, authentication screen 305 has an ID input field 301 in which the user inputs a user ID for identifying the user in this system, a password input field 302 in which the user inputs a password for the user ID, an authentication button 303 for executing authentication using the user ID and password, and an inquiry button 304 for making an inquiry when the user ID and password are unknown. The user ID and password are determined in advance before using this system.

[0023] Returning to FIG. 1, the reading unit 120 reads the identification information C attached to the recycling object T. As the identification information C, for example, a QR code (registered trademark) in which product information or parts information (for example, product number, part number, model number, serial number, manufacturing date, etc.) of the recycling object T is recorded can be used. In addition to the QR code, for example, a barcode or character information indicating a product model number may be used as the identification information C. In the case of a QR code, the address of the authentication server 200 is set as an access point as the linked Uniform Resource Locator (URL). In the case of the identification information C being character information, the user may separately obtain the URL of the authentication server 200 and access it.

[0024] The control unit 103 controls each unit and the entire terminal 100. As described above, the functions of these units are realized by the CPU 1601 executing a program. Specific processing performed by the terminal 100 will be described later using a flowchart. Returning to FIG. 1, the authentication server 200 will be described.

[0025] The authentication server 200 is a server for determining the range of information that a user can disclose as accessible information to a recycling target, and for providing the information within the range to an authenticated user. As shown in FIG. 1, the authentication server 200 has an access authority database (DB) 201 and an access range determination unit 202.

[0026] The access authority DB 201 is a database that defines the level of authority that allows a user to access information related to a recycling object T.

[0027] FIG. 4 is a diagram showing an example of the access authority DB 201. As shown in FIG. 4, the access authority DB 201 stores a serial number indicating the order of registration in the access authority DB 201, a user name of a user who uses the system, a password used by the user with the user name for access, and an access level of the user in association with each other. FIG. 4 shows that, for example, a user identified by a user ID "0001" can access the system with a password "XXX1", and the level of the range of disclosure of information accessible to recycling targets is "0". The access level "0" is the lowest access level, that is, the access level with the narrowest range of disclosure of information accessible to recycling targets. A user with this access level is a user other than the users described below, such as a purchaser of a product or part to be recycled. An example of the range of information disclosed to a user with this access level is wiring material and its material (A).

[0028] Similarly, for example, a user identified by user ID "0002" can access this system with password "XXX2", which indicates that the level of disclosure of accessible information on recyclable items is "1". This access level "1" is the next lowest level after access level "0", that is, it is the access level with the second narrowest range of disclosure of accessible information on recyclable items. A user with this access level is, for example, a general dismantler of products and parts that are subject to recycling, other than the specific dismantler described below. The information disclosed to a user with this access level includes, for example, the above (A) as well as various materials other than wiring and their materials (B).

[0029] Similarly, for example, a user identified by a user ID "0003" can access the system with a password "XXX3", and the level of disclosure of information accessible to recyclable objects is "2". The access level "2" is the next lowest level after the access levels "0" and "1", that is, the access level with the third narrowest disclosure of information accessible to recyclable objects. A user with this access level is, for example, a specific dismantler who is a dismantler with which the company has existing transactions. Examples of information disclosed to a user with this access level include, for example, the above (B) as well as a recommended dismantling order and a sorting method (C). Examples of the recommended dismantling order and sorting method include information on an efficient dismantling order for products and information on a sorting method after dismantling. By providing such information, it is possible to provide the specific dismantler, who is the user, with the efficiency of dismantling and parts sales work.

[0030] Similarly, for example, a user identified by user ID "0004" can access this system with password "XXX4", and the level of disclosure of information accessible to recycling targets is "3". This access level "3" is the next highest level after the access level "4" described later, that is, it is the access level with the second widest disclosure of information accessible to recycling targets. A user of this access level is, for example, a sales company of products or parts that are recycling targets. Examples of information disclosed to a user of this access level include, in addition to the above (C), recommended replacement parts and expected life spans (D). An example of the use of recommended replacement parts and expected life spans is when a sales company, which is a user, accesses this system during regular inspection of products or parts that are recycling targets, and checks parts with replacement deadlines, life span information, and part information and price information after replacement while visiting customers sold by the sales company. Providing such information can contribute to revitalizing sales and marketing activities during regular inspections.

[0031] Similarly, for example, a user identified by a user ID "0005" can access the system with a password "XXX5", and the level of the disclosure of information accessible to recycling targets is "4". The access level "4" is the highest level, that is, the access level with the widest disclosure of information accessible to recycling targets. A user of this access level is, for example, a manufacturer of products or parts that are recycling targets. Examples of information disclosed to a user of this access level include, in addition to the above (D), linkage to a design database and access to the design database (E). An example of linkage to a design database and access to a design database is when a manufacturing company, which is a user, can directly access the design database when a product defect occurs, and refer to product details, manufacturing history, and event information. Providing such information can support the rapid isolation, identification, and resolution of the cause of a product defect. Returning to FIG. 1, the access range determination unit 202 will be described below.

[0032] The access range determination unit 202 uses the user ID and password input from the terminal 100, the identification information C read by the reading unit 120, and the above-mentioned access authority DB 201 to determine the range of information accessible to the user for the recycling object, and provides the user with information on the recycling object within the determined range. Specific processing performed by the access range determination unit 202 will be described later using a flowchart. As described above, the function of the access range determination unit 202 is realized by the CPU 1601 executing a program. Next, the information server 300 will be described.

[0033] The information server 300 is a server that stores information on products and parts to be recycled. As shown in FIG. 1, the information server 300 has a recycle DB 301, a product DB 302, a price DB 303, and a design DB 304.

[0034] The recycle DB 301 is a DB that stores whether a product or part is eligible for recycling.

[0035] FIG. 5 is a diagram showing an example of the recycle DB 301. As shown in FIG. 5, the recycle DB 301 stores a recycle number for identifying a recycled product or part (i.e., a product or part registered as a recycle target), the name of the product or part identified by the recycle number, and the registration time of these data in association with each other. In FIG. 5, for example, the product identified by the recycle number "R001" is "product A", and "part a" composed of material X, which constitutes the product, is also a recycle target like "product A". In addition, it is shown that the data regarding the recycle number "R001" was registered on June 1, 2023.

[0036] The product DB 302 is a DB that stores detailed information about recycled products and parts.

[0037] Fig. 6 is a diagram showing an example of the product DB 302. As shown in Fig. 6, the product DB 302 stores a recycle number for identifying a product or part registered in the recycle DB 301, the name of the product or part identified by the recycle number, configuration information of the product or part, maintenance information of the product or part, and the registration time of these data in association with each other. The recycle number is linked to a product number and part number for identifying the product or part.

[0038] In FIG. 6, for example, the recycling target identified by the recycling target number "T001" is "Product A" with product number "P001", and the detailed configuration information of the product is stored as "Model number: 2022-XA01", "Serial number: A2022-001023", and "Manufacturing date January 23, 2022". It also shows that the product is composed of "Part a", "Part b", "Part c", "Insulating oil A", etc., and that the expected lifespans of each are 10 years, 10 years, 20 years, and 5 years. It also shows that these will be replaced on June 1, 2023, and that at the time of the replacement, the expected lifespans will be reached in 3 years, 3 years, 17 years, and 2 years, respectively.

[0039] The price DB 303 is a DB that stores information about the prices of products and parts.

[0040] FIG. 7 is a diagram showing an example of the price DB 303. As shown in FIG. 7, the price DB 303 stores product numbers and part numbers for identifying products and parts, the names of products and parts identified by the product numbers and part numbers, the purchase prices and maintenance prices of the products and parts, and the registration dates of these data in association with each other. FIG. 5 shows, for example, that "Product A" identified by product number "P001" has a purchase price of "AAAA yen", and the subsequent maintenance costs are "A1 yen" for the first three years from the time of purchase, and "A11 yen" every year from the fourth year onwards. In addition, it shows that the data on the product number "P001" was registered on June 1, 2023.

[0041] The design DB 304 is a DB that stores information related to the design of products and parts.

[0042] FIG. 8 is a diagram showing an example of the design DB 304. As shown in FIG. 8, the design DB 304 stores the product numbers and part numbers of the products and parts registered in the recycle DB 301, the assembly procedure of the products and parts identified by the product numbers and part numbers, the substitute products and substitute parts of the products and parts, the presence or absence of detailed information of the substitute products and substitute parts, and the registration time of these data in association with each other. FIG. 8 shows, for example, that "product A" identified by product number "P001" needs to be assembled in the order of part a (p001), part b (p002), and part c (p003). It also shows that a product identified by product number "P001'" can be acquired as a substitute product for "product A" identified by product number "P001".

[0043] Furthermore, since the detailed information of the alternative product is "available", this indicates that the access range determination unit 202 can obtain detailed information about the alternative product from another system (not shown) that cooperates with this system. For example, the access range determination unit 202 searches for information about the procurement and inventory of alternative products and alternative parts, and information about the number of days from ordering the alternative products and alternative parts to delivery date from an inventory management system (not shown) that is connected to this system via a network, using the product number "P001'" of the alternative product, and obtains this information as the above detailed information. It also indicates that the data about the product number "P001" was registered on June 1, 2023.

[0044] Next, the processing performed in this system will be described.

[0045] FIG. 9 is a diagram showing an example of a procedure of the recycling support process performed in this system.

[0046] First, the reading unit 102 of the terminal 100 accepts an operation from a user and reads the identification information C attached to the recycling object T (S901). Since the identification information C includes a QR code related to the recycling object T, the control unit 103 accesses the address of the authentication server 200 indicated by the QR code read by the reading unit 102 via a communication unit that communicates according to a predetermined standard (not shown) (S902).

[0047] When the authentication server 200 is accessed, the screen display unit 101 displays the authentication screen shown in Fig. 3 and accepts input of authentication information including a user ID and a password from the user. Thereafter, the control unit 103 transmits to the authentication server 200 the product information and parts information (e.g., product number, part number, model number, serial number, manufacturing date, etc.) read from the identification information C together with the authentication information. The access range determination unit 202 of the authentication server 200 refers to the authentication information received from the terminal 100 and the access authority DB 201 shown in Fig. 4, and determines what access level the user using this system has (S904).

[0048] The access range determination unit 202 reads out information about the recycling object T corresponding to the access level determined in S904 from the information stored in the information server 300, and transmits it to the terminal 100. The screen display unit 101 of the terminal 100 displays the information about the recycling object T received from the authentication server 200 (S905).

[0049] FIG. 10 is a diagram showing an example of a provided information display screen on which the screen display unit 101 of the terminal 100 displays information about the recycling object T provided by the authentication server 200 according to the access level to the information about the recycling object T.

[0050] As shown in FIG. 10, the provided information display screen 310 displays basic information 311 such as product information and parts information of the recycling target T recorded in the identification information C. In FIG. 10, the model number "2022-XA01", serial number "A2022-001023", and manufacturing date "2022 / 1 / 23" of the recycling target T recorded in the identification information C are displayed as the basic information 311. Since the basic information 311 is information recorded in the identification information C, it can be provided to, for example, a user with an access level "0", that is, all users registered in this system.

[0051] Furthermore, the provided information display screen 310 displays, for example, information other than the basic information 311, such as maintenance information related to parts. In this example, a list of parts with a limited life span 312 is displayed as an example of maintenance information. In FIG. 10, the list of parts with a limited life span 312 indicates that, among the parts constituting the product to be recycled T recorded in the identification information C, parts a and b have an expected life span of 10 years, with three years remaining until the expected life span. Similarly, the list indicates that part c has an expected life span of 20 years, with 17 years remaining until the expected life span, and that insulating oil A has an expected life span of 5 years, with two years remaining until the expected life span.

[0052] The information displayed in the limited life parts list 312 may be acquired as follows. For example, the access range determination unit 202 uses the product number or part number recorded in the identification information C received from the terminal 100 together with the user ID and password to read the product number or part number that matches the product number or part number from the product DB 302 shown in Fig. 6. The access range determination unit 202 can read and acquire the maintenance information stored in association with the read product number or part number.

[0053] The information displayed in the limited life parts list 312 is information stored in the product DB 302. Therefore, the information can be provided to users with an access level of "3," that is, to sales companies and their salespeople who are registered in the system and need to know maintenance information such as the lifespan and replacement timing of products and parts.

[0054] Also, on the provided information display screen 310, for example, information other than the basic information 311, such as replacement information related to parts, is displayed. In this example, a replacement parts list 313 is displayed as an example of replacement information. In FIG. 10, the replacement parts list 313 shows that, among the parts constituting the product of the recycling target T recorded in the identification information C, the replacement parts for part a are three types of parts, MT02, MT03, and AX04, and the replacement parts for part b are three types of parts, MT03, MT04, and AX05. Also, it shows that the replacement parts for part c are three types of parts, F25, F26, and R14, and the replacement oils for the insulating oil A are two types of oils, OL05 and OL08.

[0055] The information displayed on the alternative parts list 313 may be acquired as follows. For example, the access range determination unit 202 uses the product number or part number recorded in the identification information C received from the terminal 100 together with the user ID and password to read the product number or part number that matches the product number or part number from the design DB 304 shown in Fig. 8. The access range determination unit 202 can read and acquire the alternative products and parts stored in correspondence with the read product number or part number.

[0056] The information displayed on the substitute parts list 313 is information stored in the design DB 304. Therefore, for example, the information can be provided to a user with an access level of "4," that is, among the users registered in this system, a manufacturing company or its employees who need to know design information such as the design procedure, assembly procedure, and manufacturing method of a product or part.

[0057] Although the basic information 311, the limited-life parts list 312, and the alternative parts list 313 have been described with reference to FIG. 10, various pieces of information stored in the information server 300 may be combined and displayed on the provided information display screen 310 according to the access level.

[0058] For example, for a user with access level "1", in addition to the basic information 311, the access range determination unit 202 may further use the product number or part number recorded in the identification information C to read and acquire the material (e.g., material X) of the part name corresponding to the product number or part number stored in the recycle DB 301 shown in Fig. 5. This makes it possible to provide the general dismantling contractor with information on the work environment to be prepared during dismantling, such as tools, work clothes, and protective clothing required during dismantling.

[0059] Also, for example, for a user with access level "2", in addition to the basic information 311 and the above-mentioned component materials, the access range determination unit 202 may further use the product number and component number recorded in the identification information C to read and acquire the dismantling procedure of the product or component corresponding to the product number or component number stored in the design DB 304 shown in FIG. 8. The access range determination unit 202 reads the assembly procedure stored in the design DB 304 and sets the reverse order as the dismantling procedure. This makes it possible to present a specific dismantling procedure to the specified dismantler, and as a result, it becomes possible to dismantle products and parts efficiently.

[0060] As described above, the recycling support system according to this embodiment, as described with reference to Figs. 1, 9, etc., is a recycling support system that supports the recycling of a recycling object by disclosing information about the recycling object by a computer having a processor and a memory. The processor authenticates the user based on the authentication information (e.g., user ID and password) of the user input to the computer and the registered authentication information (e.g., user ID and password registered in advance as a regular user), and changes the range of information about the recycling object to be disclosed according to the access level of the authenticated user using the identification information (e.g., QR code) attached to the recycling object and the access authority information (e.g., access authority DB201) that defines the access level to the information about the recycling object for each user. This meets the need to change the range of information about the recycling object to be disclosed according to the authority of the person accessing the recycling object.

[0061] Specifically, when a user accesses a recycling-related database, it becomes possible to control the scope and content of access, or the scope and amount of scheduled information and public information according to the authority granted in advance. This makes it possible, for example, to provide incentives to businesses that do business with the company, and to facilitate replacement and update proposals for individual parts as necessary.

[0062] As described with reference to Figs. 9 and 10, the computer has a display device (e.g., output device 1605), and the processor outputs the information on the recycle target with the changed range to the display device. This allows the information on the recycle target to be presented to the user. The user can easily check the information on the recycle target according to his / her authority.

[0063] As described with reference to FIG. 1 and the like, the computer has a reading device (e.g., input device 1606), and the processor obtains information about the recycling target by reading the identification information with the reading device. This allows the user to easily obtain information contained in the identification information.

[0064] 4, 9, etc., the computer holds in the memory a table (e.g., access authority DB201) in which the registered authentication information of the user, the access level to the information on the recycling object, and the range of the information on the recycling object corresponding to the access level are associated with each other as the access authority information. This makes it easy to perform maintenance such as registration, change, and deletion of users and their access levels.

[0065] As described with reference to Figures 8, 10, etc., the computer holds in the memory a table (e.g., design DB 304) that associates information about the substitute product to be recycled with the presence or absence of detailed information about the substitute product, and the processor obtains and outputs the detailed information (e.g., information about the procurement and inventory of substitute products and substitute parts) from another system (e.g., an inventory management system) when the authenticated user's access level to the information about the recycled product meets a predetermined condition (e.g., a condition that the access level is "4" or higher) and there is detailed information about the substitute product for the recycled product (e.g., when the presence or absence of detailed information in design DB 304 is "present"). This makes it possible to grasp not only direct information such as the configuration of the substitute product or substitute part, but also information about the cost of replacing a product or part with a substitute product or substitute part.

[0066] The present invention is not limited to the above-described embodiment as it is, and in the implementation stage, the components may be modified and embodied within the scope of the gist of the invention, or multiple components disclosed in the above-described embodiment may be appropriately combined and implemented. For example, in the above embodiment, user authentication is performed using a user ID and a password. However, in an environment where the user ID and password may be leaked or circulated, secure authentication may not always be possible. Therefore, in order to take measures against leakage, etc., when the access level is above a certain threshold level (for example, level 2 or level 3 or higher), a mechanism for performing authentication each time, such as a one-time password, may be additionally introduced.
